πŸ“‹ Key Information Summary

πŸ“‹
  • A structured cardiovascular history must systematically address the six cardinal symptoms: chest pain, dyspnoea, palpitations, syncope/pre-syncope, ankle oedema, and claudication.
  • Chest pain characterisation using SOCRATES (Site, Onset, Character, Radiation, Associated symptoms, Timing, Exacerbating/relieving factors, Severity) distinguishes cardiac from non-cardiac causes.
  • Typical angina is substernal, provoked by exertion or stress, and relieved by rest or GTN within 5 minutes; atypical features should prompt consideration of ACS, aortic dissection, or PE.
  • Acute coronary syndrome (ACS) presents with crushing/pressure-like chest pain radiating to the left arm, jaw, or back with associated diaphoresis, nausea, and dyspnoea β€” activate the ACS pathway immediately.
  • Aortic dissection classically presents with sudden-onset, tearing chest pain radiating to the back with pulse or blood pressure differential between limbs β€” this is a time-critical emergency.
  • The jugular venous pressure (JVP) is assessed at 45Β° head elevation; elevated JVP (>4 cm above the sternal angle) suggests right heart failure, fluid overload, cardiac tamponade, or SVC obstruction.
  • The normal apex beat is located in the 5th intercostal space, mid-clavicular line; displacement suggests cardiomegaly, a sustained/heaving apex indicates pressure overload (e.g., aortic stenosis, hypertension).
  • Heart sounds: S1 (mitral and tricuspid closure, louder at apex) and S2 (aortic and pulmonic closure, louder at base); S3 in systolic heart failure; S4 in diastolic dysfunction or hypertension.
  • Systolic murmurs include aortic stenosis (ejection systolic, loudest at right upper sternal border, radiating to carotids), mitral regurgitation (pansystolic, loudest at apex radiating to axilla), and VSD.
  • Diastolic murmurs include aortic regurgitation (early diastolic, left sternal edge, best heard sitting forward) and mitral stenosis (mid-diastolic rumble with loud S1, loudest at apex).
  • Peripheral examination includes bilateral radial, brachial, femoral, popliteal, dorsalis pedis, and posterior tibial pulses, plus assessment for ankle oedema, skin changes, and peripheral temperature.
  • Heart failure affects approximately 500,000 Australians; valvular disease remains prevalent in Indigenous Australians due to rheumatic heart disease (RHD) burden.
  • Aboriginal and Torres Strait Islander Australians experience cardiovascular disease at 1.7 times the rate of non-Indigenous Australians; rheumatic heart disease rates in remote NT communities are among the highest globally.
  • Always document the cardiovascular risk factor profile: smoking, diabetes, hypertension, dyslipidaemia, family history, and use the Australian cardiovascular risk calculator (AusCVDRisk) for patients aged 45–74 years.

Introduction & Australian Epidemiology

Cardiovascular disease (CVD) remains the leading cause of death in Australia, responsible for approximately 26% of all deaths annually (AIHW, 2023). A systematic approach to cardiovascular history-taking and examination is a foundational clinical skill for all medical practitioners, enabling accurate differential diagnosis, risk stratification, and timely intervention.

The cardiovascular examination integrates inspection, palpation, and auscultation to evaluate cardiac structure and function, peripheral vascular integrity, and haemodynamic status. Combined with a thorough history β€” particularly around chest pain characterisation β€” this assessment guides further investigation pathways including electrocardiography (ECG), echocardiography, cardiac biomarkers, and advanced imaging.

Australian Burden of Cardiovascular Disease

  • Prevalence: An estimated 1.2 million Australians aged 18+ have one or more conditions related to heart, stroke, or vascular disease (AIHW 2023).
  • Hospitalisation: CVD accounts for over 600,000 hospital admissions per year in Australia.
  • Ischaemic heart disease (IHD): The single leading cause of death, responsible for approximately 17,500 deaths annually.
  • Heart failure: Approximately 500,000 Australians live with heart failure, with prevalence increasing with age (affecting >10% of those aged β‰₯75 years).
  • Stroke: Over 27,000 strokes per year; a leading cause of disability.
  • Indigenous disparity: Aboriginal and Torres Strait Islander Australians experience CVD at 1.7 times the rate of non-Indigenous Australians, with rheumatic heart disease (RHD) 68 times more common in Indigenous than non-Indigenous children in the Northern Territory.
  • Gender considerations: Women are more likely to present with atypical ACS symptoms (fatigue, dyspnoea, nausea) leading to delayed diagnosis and higher in-hospital mortality.
⚠️
Red flag β€” Always consider acute coronary syndrome (ACS) in any patient presenting with acute chest pain. Initiate the local ACS pathway (aspirin 300 mg, GTN, 12-lead ECG within 10 minutes) while continuing your assessment. Time-critical conditions such as STEMI, aortic dissection, and pulmonary embolism require emergent management.

Cardiovascular History

A structured cardiovascular history must systematically address the six cardinal cardiovascular symptoms. Each symptom should be explored using a standardised approach (SOCRATES for pain, or the mnemonic "PCQRST" where appropriate) to build a comprehensive clinical picture.

The Six Cardinal Symptoms

Symptom Key Questions Diagnostic Significance
Chest pain SOCHRATES; exertional vs rest; character; radiation; duration; relieving factors ACS, stable angina, pericarditis, dissection, PE, musculoskeletal, oesophageal
Dyspnoea Onset (acute vs chronic); NYHA class I–IV; orthopnoea; PND; positional; exertional tolerance (e.g., flights of stairs) Heart failure, valvular disease, pulmonary hypertension, arrhythmia
Palpitations Onset/offset (sudden vs gradual); regularity; duration; associated symptoms (dizziness, chest pain, syncope); precipitants SVT, atrial fibrillation/flutter, ventricular ectopy, VT, panic disorder
Syncope / Pre-syncope Prodrome; position (exertional, postural); witnessed vs unwitnessed; injury; post-event confusion; medications Vasovagal, orthostatic, cardiac (aortic stenosis, HOCM, arrhythmia), pulmonary embolism
Ankle oedema Unilateral vs bilateral; pitting vs non-pitting; associated weight gain; time of day; medication (CCBs); comorbidities Right heart failure, biventricular failure, DVT, nephrotic syndrome, liver disease, medication-related
Claudication Walking distance before pain; rest pain; site (buttock/thigh/calf); time to relief; smoking history; DM Peripheral arterial disease (PAD); critical limb ischaemia if rest pain or tissue loss

Additional History Components

  • Past medical history: Previous MI, PCI, CABG, valvular surgery, rheumatic fever, endocarditis, congenital heart disease, hypertension, diabetes, CKD, dyslipidaemia, AF, DVT/PE.
  • Medications: Antiplatelets (aspirin, clopidogrel, ticagrelor), anticoagulants (warfarin, DOACs), antihypertensives (ACEi, ARBs, CCBs, beta-blockers, thiazides), statins, digoxin, diuretics, antiarrhythmics. Document adherence and recent changes.
  • Family history: Premature IHD (<55 male first-degree relative, <65 female first-degree relative), sudden cardiac death (<40 years), familial hypercholesterolaemia, HOCM, long QT syndrome, Marfan syndrome, aortopathies.
  • Social history: Smoking (pack-years, current/ex/never), alcohol intake, recreational drugs (cocaine, methamphetamine β€” important for ACS in young patients), physical activity level, occupation.
  • Allergies: Especially iodinated contrast, aspirin, heparin, latex β€” relevant for procedural planning.

NYHA Functional Classification (Heart Failure)

Class I
No Limitation
Ordinary physical activity does not cause undue dyspnoea or fatigue.
No restriction
Class II
Mild Limitation
Comfortable at rest; ordinary physical activity causes symptoms.
Slight activity restriction
Class III
Marked Limitation
Comfortable at rest; less-than-ordinary activity causes symptoms.
Marked activity restriction
Class IV
Symptomatic at Rest
Unable to carry out any physical activity without symptoms; symptoms at rest.
Bedbound / chair-bound

Chest Pain Characterisation

Chest pain is the most common presenting symptom triggering cardiovascular assessment. Accurate characterisation is essential to discriminate life-threatening causes from benign aetiologies. The differential diagnosis spans cardiac, pulmonary, vascular, gastrointestinal, musculoskeletal, and psychological causes.

SOCRATES Framework for Chest Pain

S
Site
Substernal (cardiac), left-sided (pericardial, pleuritic), epigastric (inferior MI, GI), back (dissection)
O
Onset
Sudden (dissection, PE, pneumothorax) vs gradual; exertional (angina) vs rest (unstable)
C
Character
Pressure/tightness (anginal), tearing (dissection), sharp/pleuritic (pericarditis, PE), burning (reflux)
R
Radiation
Left arm/jaw (IHD), back (dissection), shoulder (pericarditis, diaphragmatic irritation)
A
Associations
Diaphoresis, nausea, dyspnoea (ACS); fever (pericarditis); haemoptysis (PE)
T
Timing
Duration: minutes (angina), hours (MI, pericarditis), seconds (non-cardiac); constant vs intermittent
E
Exacerbating / Relieving
Exertion/relief with rest/GTN (angina); worse lying flat/pericarditis; worse inspiration (pleuritic)
S
Severity
1–10 scale; worst-ever pain (dissection); associated anxiety/fear of death ("angor animi")

Differential Diagnosis of Chest Pain

Condition Onset / Character Key Features First-Line Investigation
Stable Angina Exertional, substernal pressure/heaviness; ≀15 min; relieved by rest/GTN Predictable pattern; no rest pain; risk factors present 12-lead ECG (may be normal); exercise stress test; CT coronary angiogram
Acute Coronary Syndrome (ACS) Sudden or crescendo; crushing/pressure; >15–20 min; radiating to L arm, jaw, back Associated diaphoresis, nausea, dyspnoea, sense of doom; may be atypical in women, elderly, diabetics 12-lead ECG within 10 min; high-sensitivity troponin (hs-cTn) at 0 and 1–3 h; ACS pathway activation
Pericarditis Acute onset; sharp, pleuritic; worse lying flat; better sitting forward Recent viral illness; pericardial friction rub; widespread saddle-shaped ST elevation on ECG ECG; echocardiography (pericardial effusion); inflammatory markers (CRP, ESR)
Aortic Dissection Sudden onset; maximal at onset; tearing/ripping; radiating to back (interscapular) Hypertension history; pulse deficit; BP differential >20 mmHg between limbs; aortic regurgitation murmur CT aortogram (gold standard); CXR (widened mediastinum); TTE/TOE
Pulmonary Embolism Sudden onset; pleuritic; associated dyspnoea, tachycardia, haemoptysis DVT risk factors (immobilisation, surgery, OCP, malignancy); right heart strain CT pulmonary angiogram (CTPA); D-dimer (if low Wells score); ECG (S1Q3T3, RBBB)
Musculoskeletal Variable; reproducible with palpation/movement; positional; well-localised Costochondritis (Tietze syndrome), intercostal muscle strain; no systemic features Clinical diagnosis; CXR if indicated; no cardiac biomarkers required
Oesophageal (GORD / Spasm) Burning/retrosternal; postprandial; relieved by antacids; may mimic angina Relationship to meals; acid taste; no exertional component; responds to PPI trial PPI trial; endoscopy if recurrent; oesophageal pH monitoring if atypical
🚨
Time-critical emergency: Aortic dissection presents with sudden-onset, severe, tearing chest pain radiating to the back. Do NOT delay for imaging if clinically suspected β€” manage blood pressure urgently (target SBP 100–120 mmHg with IV labetalol or GTN), obtain CT aortogram, and activate the cardiothoracic surgical team. Mortality increases by 1–2% per hour untreated.
⚠️
Atypical presentations: Women, elderly patients (β‰₯75 years), and people with diabetes mellitus frequently present with atypical ACS symptoms β€” dyspnoea without chest pain, fatigue, nausea/vomiting, back pain, or epigastric discomfort. Maintain a high index of suspicion and obtain a 12-lead ECG and troponin in these groups with unexplained symptoms.

Cardiovascular Examination

The cardiovascular examination follows a systematic approach: general inspection, hands, face, neck (JVP and carotids), praecordium (inspection, palpation, auscultation), and peripheral vascular assessment. Always ensure patient comfort, warmth, and privacy. Expose the chest adequately while maintaining dignity.

Step-by-Step Cardiovascular Examination

1
General Inspection
End of bed: dyspnoea, central/peripheral cyanosis, malar flush (mitral sthenosis), xanthelasma, tendon xanthomas (familial hypercholesterolaemia), Marfanoid habitus, scars (CABG median sternotomy, valve replacement, pacemaker/ICD generator site)
2
Hands
Clubbing (infective endocarditis, cyanotic congenital HD); splinter haemorrhages (endocarditis, vasculitis); Osler nodes (painful, endocarditis); Janeway lesions (painless, endocarditis); peripheral cyanosis; nicotine staining; peripheral vasodilation (warm in COβ‚‚ retention, cold in low output)
3
Face & Eyes
Conjunctival pallor (anaemia β€” exacerbates heart failure); corneal arcus (premature if <50 β€” hyperlipidaemia); xanthelasma; central cyanosis (tongue, lips); dental hygiene (endocarditis risk)
4
Neck β€” JVP
Assess at 45Β° head elevation; normal JVP ≀4 cm above sternal angle; waveform (a wave = atrial contraction, v wave = ventricular filling); elevated JVP: RHF, fluid overload, tamponade, SVC obstruction, tricuspid stenosis
5
Carotid Arteries
Palpate one at a time; character (slow-rising in aortic stenosis, bounding in aortic regurgitation, bisferiens in mixed AS/AR); auscultate for bruits (carotid stenosis)
6
Praecordium β€” Inspection & Palpation
Visible apex beat; scars; pacemaker; heaves (parasternal β€” RV hypertrophy); thrills (palpable murmurs); apex beat location, character (thrusting = volume overload, heaving = pressure overload, tapping = loud S1 in mitral stenosis)
7
Auscultation
Systematic: aortic area (2nd ICS right) β†’ pulmonary area (2nd ICS left) β†’ Erb's point (3rd ICS left) β†’ tricuspid (left lower sternal edge) β†’ mitral/apex (5th ICS MCL); listen for S1, S2, added sounds, murmurs; use both bell and diaphragm

Jugular Venous Pressure (JVP)

The JVP reflects right atrial pressure and is assessed with the patient at 45Β°, head turned slightly to the left. The internal jugular vein is preferred as it runs directly to the right atrium without valves.

JVP Finding Significance
Elevated JVP (>4 cm above sternal angle) Fluid overload, right heart failure, cardiac tamponade, constrictive pericarditis, SVC obstruction, pulmonary hypertension
Giant a waves Tricuspid stenosis, pulmonary hypertension, pulmonary stenosis, right atrial myxoma
Cannon a waves AV dissociation (complete heart block, ventricular tachycardia) β€” atrial contraction against closed tricuspid valve
Giant v waves (cv waves) Tricuspid regurgitation
Slow y descent Tricuspid stenosis, right atrial myxoma
Rapid x and y descent (Friedreich sign) Constrictive pericarditis (Friedreich's sign)
Kussmaul sign (JVP rises with inspiration) Constrictive pericarditis, restrictive cardiomyopathy, right ventricular infarction, severe RHF
Abdominojugular reflux (hepatojugular reflux) Sustained pressure on the RUQ for >15 s causing sustained JVP elevation β‰₯4 cm suggests right heart failure or fluid overload

Apex Beat

Apex Character Description Suggests
Normal 5th ICS, mid-clavicular line; gentle tapping; ≀2 cm diameter Normal cardiac size and function
Displaced (>MCL) Lateral and/or inferior displacement; diffuse Dilated cardiomyopathy, LV dilatation, heart failure, large pericardial effusion
Sustained / Heaving Forceful, sustained lift; ≀3 cm; resists palpation Pressure overload: aortic stenosis, systemic hypertension, HOCM
Thrusting / Hyperdynamic Forceful but brief; diffuse; may be displaced Volume overload: aortic regurgitation, mitral regurgitation, VSD
Tapping Palpable S1 with the hand Mitral stenosis (loud S1)
Double impulse Two beats palpable per cardiac cycle HOCM

Heart Sounds β€” S1 and S2

S1 (first heart sound) β€” closure of the mitral (M1) and tricuspid (T1) valves. Best heard at the apex. Loud S1: mitral stenosis (mobile valve), short PR interval, hyperdynamic states. Soft S1: mitral regurgitation, long PR interval (first-degree heart block), poor LV function, calcified immobile mitral valve.

S2 (second heart sound) β€” closure of the aortic (A2) and pulmonic (P2) valves. Best heard at the base. Normally split (A2 before P2; wider on inspiration). Physiological splitting: normal. Fixed splitting: atrial septal defect (ASD). Paradoxical (reversed) splitting: LBBB, aortic stenosis, right ventricular pacing. Wide splitting: RBBB, pulmonary stenosis, right heart delay. Loud P2: pulmonary hypertension. Soft A2: calcified aortic stenosis.

Added Heart Sounds β€” S3 and S4

S3 (Third Heart Sound)

Low-pitched sound in early diastole (rapid ventricular filling). Best heard at the apex with the bell, patient in left lateral decubitus position. Often physiological in young adults (<35 years) and pregnant women. Pathological S3: systolic heart failure, volume overload, dilated cardiomyopathy, significant mitral/aortic regurgitation. Often palpable as the "double impulse" of the apex beat.

S4 (Fourth Heart Sound)

Low-pitched, late-diastolic sound (atrial contraction against a stiff ventricle). Best heard at the apex with the bell. Never normal in the absence of a PR interval <0.12 s. Causes: systemic hypertension (LVH), aortic stenosis (LVH), HOCM, acute MI (reduced compliance), restrictive cardiomyopathy. Not heard in atrial fibrillation (no effective atrial contraction).

Murmurs β€” Systolic

Murmur Timing & Character Location & Radiation Associated Findings
Aortic Stenosis (AS) Ejection systolic (crescendo-decrescendo); loudest in mid-systole Right 2nd ICS (aortic area); radiates to carotid arteries Slow-rising carotid pulse (pulsus parvus et tardus); narrow pulse pressure; sustained/heaving apex; soft A2; S4; may have ejection click (bicuspid valve); thrill at right sternal edge
Mitral Regurgitation (MR) Pansystolic (holosystolic); blowing quality; constant from S1 to S2 Apex (mitral area); radiates to the left axilla (posterolateral jet) or base of the heart (anteromedial jet) Displaced, hyperdynamic apex; loud S1 (unless severe); S3 (volume overload); soft S2; atrial fibrillation (LA dilatation); elevated JVP in decompensated failure
Tricuspid Regurgitation (TR) Pansystolic; increases with inspiration (Carvallo sign) Left lower sternal edge (tricuspid area); no radiation to axilla Giant v waves in JVP; pulsatile liver; elevated JVP; right heart failure signs
Ventricular Septal Defect (VSD) Pansystolic, harsh Left lower sternal border (Erb's point); may have a thrill Small VSD = loud murmur, large VSD = quieter (lower gradient); loud P2 if pulmonary hypertension develops
Pulmonary Stenosis (PS) Ejection systolic; crescendo-decrescendo Left 2nd ICS (pulmonary area); may radiate to back/left shoulder Wide splitting of S2; ejection click (valvular); right ventricular heave; elevated JVP in severe PS
HOCM (Hypertrophic Obstructive Cardiomyopathy) Ejection systolic; dynamic β€” louder with Valsalva/standing, softer with squatting Left lower sternal edge; does not radiate to carotids Double apex beat; brisk carotid upstroke with bifid pulse; S4; family history of sudden cardiac death

Murmurs β€” Diastolic

Murmur Timing & Character Location & Radiation Associated Findings
Aortic Regurgitation (AR) Early diastolic; high-pitched, blowing, decrescendo; best heard at end-expiration Left sternal edge (Erb's point); best heard with patient sitting forward Collapsing (water-hammer) pulse; wide pulse pressure; de Musset sign (head bobbing); Quincke's sign (nail bed pulsation); Austin Flint murmur (mid-diastolic rumble at apex); displaced hyperdynamic apex; S3
Mitral Stenosis (MS) Mid-diastolic; low-pitched rumble; presystolic accentuation (if sinus rhythm); opening snap (early diastole) Apex (best heard in left lateral decubitus with bell); localised β€” does not radiate Loud S1 (tapping apex); loud P2 (pulmonary hypertension); opening snap (mobile valve); right heart failure signs; AF (LA dilatation); malar flush; low-volume pulse
Pulmonary Regurgitation (PR) Early diastolic; Graham Steell murmur if secondary to pulmonary hypertension Left sternal edge (pulmonary area) Right ventricular heave; loud P2; signs of pulmonary hypertension
Tricuspid Stenosis (TS) Mid-diastolic rumble; presystolic if sinus rhythm Left lower sternal edge; increases with inspiration Elevated JVP with giant a waves; hepatomegaly; right heart failure; often associated with rheumatic mitral disease

Special Manoeuvres in Auscultation

Manoeuvre Physiological Effect Clinical Use
Left lateral decubitus position Brings the apex closer to the chest wall Best for mitral stenosis (bell at apex), S3, S4
Sitting forward, end-expiration Brings the aortic root closer to the chest wall Best for aortic regurgitation (diaphragm at left sternal edge)
Valsalva manoeuvre (strain phase) Decreases preload HOCM murmur louder; most other murmurs softer; mitral valve prolapse click moves earlier
Squatting Increases preload and afterload HOCM murmur softer; MVP click moves later; most other murmurs louder
Deep inspiration Increases venous return to the right heart Right-sided murmurs louder (TR, TS, PS); Carvallo sign in TR
Amyl nitrite inhalation Decreases afterload (vasodilation) β€” transient AS murmur louder; AR murmur softer; MR murmur softer

Grading of Systolic Murmurs

Grade 1
Barely Audible
Only audible in a quiet room with careful listening by an experienced clinician.
Grade 2
Soft
Faint but audible immediately on auscultation.
Grade 3
Moderate
Easily audible; no thrill.
Grade 4
Loud
Loud with a palpable thrill.
Grade 5
Very Loud
Audible with stethoscope partially off the chest; palpable thrill.
Grade 6
Loudest Possible
Audible without the stethoscope on the chest wall; palpable thrill.

Peripheral Signs & Common Conditions

Peripheral Vascular Examination

A comprehensive peripheral vascular assessment is an essential component of every cardiovascular examination. It evaluates arterial supply, venous return, and identifies signs of systemic disease (peripheral arterial disease, deep vein thrombosis, chronic venous insufficiency, aortic pathology).

Peripheral Pulses

Pulse Location Assessment
Radial Lateral wrist, proximal to the radial styloid Rate, rhythm (regular, irregularly irregular = AF, regularly irregular = second-degree heart block), character (slow-rising, collapsing, bisferiens), volume (low in shock/AS, bounding in AR/COβ‚‚ retention), radio-radial delay (aortic dissection/coarctation)
Brachial Medial antecubital fossa, medial to biceps tendon Blood pressure measurement; Korotkoff sounds; character assessment
Carotid Medial to sternocleidomastoid at the level of the thyroid cartilage Palpate ONE side at a time; character (slow-rising = AS, collapsing = AR, bisferiens = combined AS/AR); auscultate for bruits
Femoral Midpoint of the inguinal ligament Palpate both simultaneously; note femoral-femoral delay (coarctation of the aorta); compare with radial pulse timing
Popliteal Popliteal fossa, deep behind the knee (flex knee to ~30Β°) Bimanual technique with both hands; often the most difficult pulse to locate
Posterior tibial Posterior to the medial malleolus Present in >95% of normal individuals; absent in significant peripheral arterial disease
Dorsalis pedis Dorsum of the foot, lateral to the extensor hallucis longus tendon Congenitally absent in ~8% of the population; assess in conjunction with posterior tibial

Ankle Oedema β€” Assessment

Ankle oedema is assessed by applying firm, sustained pressure over the medial malleolus and the dorsum of the foot for 5 seconds. Pitting oedema leaves a persistent indentation and is graded on a scale:

Trace
Barely Perceptible
Minimal indentation, resolves within seconds.
1+
Mild
2 mm indentation, resolves in <15 seconds. Ankle level only.
2+
Moderate
4 mm indentation, resolves in 15–30 seconds. Up to mid-calf.
3+
Severe
6 mm indentation, resolves in 30–60 seconds. Up to the knee.
4+
Very Severe
8 mm indentation lasting >2 minutes. Extends above the knee; may involve genital oedema and ascites.

Differential diagnosis of bilateral ankle oedema: biventricular heart failure, nephrotic syndrome, chronic liver disease (hypoalbuminaemia), bilateral DVT, chronic venous insufficiency, medication-related (amlodipine and other CCBs, NSAIDs, corticosteroids, thiazolidinediones), lymphoedema (non-pitting), myxoedema (non-pitting), hypoalbuminaemia of any cause.

Differential diagnosis of unilateral ankle oedema: deep vein thrombosis (DVT β€” requires urgent assessment with Wells score and D-dimer), cellulitis, chronic venous insufficiency, popliteal cyst (Baker's cyst), lymphoedema, trauma, compartment syndrome.

⚠️
Unilateral leg swelling: Always consider DVT. Calculate the Wells score; if score β‰₯2, proceed to D-dimer or compression ultrasound. If D-dimer is elevated or Wells score is high, obtain urgent duplex ultrasound. Do not rely on D-dimer alone in patients with active malignancy, pregnancy, or post-surgical state β€” go directly to imaging.

Common Cardiovascular Conditions

Heart Failure

Heart failure (HF) is a clinical syndrome resulting from any structural or functional impairment of ventricular filling or ejection. In Australia, approximately 500,000 people live with heart failure, and the condition accounts for over 70,000 hospital admissions annually. The prevalence increases significantly with age, affecting >10% of Australians aged β‰₯75 years.

Heart Failure with Reduced Ejection Fraction (HFrEF)

LVEF ≀40%. Most common causes: ischaemic heart disease (post-MI), dilated cardiomyopathy (idiopathic, alcohol, peripartum, myocarditis), chronic hypertension. Key examination findings: displaced, diffuse, hyperdynamic apex; S3 gallop; pansystolic murmur of functional MR; elevated JVP; bilateral basal crackles; bilateral pitting ankle oedema; hepatomegaly.

Heart Failure with Preserved Ejection Fraction (HFpEF)

LVEF β‰₯50% with evidence of diastolic dysfunction. Most common in elderly women with hypertension, obesity, diabetes mellitus, atrial fibrillation, and renal impairment. Key examination findings: S4 gallop; blood pressure elevation; may have preserved apex; signs of congestion (elevated JVP, crackles, oedema) may be subtle or absent until decompensation.

πŸ“‹
Heart failure workup (first presentation): BNP or NT-proBNP (if BNP >100 pg/mL or NT-proBNP >300 pg/mL β€” further investigation indicated); transthoracic echocardiography (assess LVEF, wall motion, valvular function, diastolic parameters); FBC, UEC, LFT, TFT, HbA1c, lipid panel, iron studies (ferritin and transferrin saturation); 12-lead ECG; CXR (cardiomegaly, pulmonary congestion, pleural effusions).

Valvular Heart Disease

Valve Lesion Common Cause Key Exam Findings Investigation
Aortic Stenosis Degenerative calcification (elderly); bicuspid aortic valve (younger); rheumatic fever Ejection systolic murmur β†’ carotids; slow-rising pulse; narrow BP; heaving apex; S4; soft A2; ejection click (bicuspid); thrill at RSE TTE (valve area, gradient, jet velocity); dobutamine stress echo if low-flow, low-gradient AS
Aortic Regurgitation Bicuspid valve; endocarditis; aortic root dilation (Marfan, aortitis); rheumatic disease Early diastolic murmur (LSE, sitting forward); collapsing pulse; wide pulse pressure; de Musset sign; displaced hyperdynamic apex; Austin Flint murmur; S3 TTE (regurgitant severity, LVEF, aortic root dimensions); MRI for aortic root assessment
Mitral Stenosis Rheumatic heart disease (most common worldwide and in Indigenous Australians); degenerative; congenital (rare) Mid-diastolic rumble (apex, left lateral, bell); loud S1 (tapping apex); opening snap; presystolic accentuation (if SR); AF; elevated JVP; malar flush; pulmonary hypertension signs TTE (valve area, mean gradient, pulmonary artery pressure); TOE pre-commissurotomy
Mitral Regurgitation Mitral valve prolapse; ischaemic papillary muscle dysfunction; rheumatic disease; endocarditis; dilated cardiomyopathy (functional MR) Pansystolic murmur (apex β†’ axilla); displaced hyperdynamic apex; S3; AF; elevated JVP in decompensation TTE (mechanism, severity, LVEF, LA size); TOE pre-surgical planning

Congenital Heart Disease β€” Key Lesions in Adults

With improved paediatric cardiac surgery, increasing numbers of adults with repaired congenital heart disease (CHD) present to adult medical services. Key lesions encountered:

πŸ«€
Atrial Septal Defect (ASD)
Ostium secundum (most common) Β· Ostium primum Β· Sinus venosus
Examination Wide, fixed splitting of S2; ejection systolic murmur (pulmonary flow); right ventricular heave; diastolic rumble at LLSB (tricuspid flow); signs of pulmonary hypertension if large/repaired late
Key investigation TTE (shunt, RV dilation); bubble study (right-to-left shunt); TOE if secundum ASD being considered for device closure
πŸ«€
Ventricular Septal Defect (VSD)
Membranous (most common) Β· Muscular Β· Inlet Β· Outlet
Examination Pansystolic murmur (LLSB Β± thrill); loud P2 if pulmonary hypertension develops; small VSD = louder murmur (higher gradient); large VSD = quieter murmur (Eisenmenger syndrome if irreversible pulmonary HT)
Key investigation TTE (shunt size, gradient, RVSP); cardiac MRI for quantification
πŸ«€
Coarctation of the Aorta
Juxtaductal narrowing Β· Associated with bicuspid aortic valve in 50–85%
Examination Upper limb hypertension; radio-femoral delay; BP differential (>20 mmHg upper vs lower limbs); continuous murmur (collateral vessels β€” posterior chest); rib notching on CXR (collateral intercostal arteries); associated bicuspid aortic valve murmur
Key investigation CT or MRI aorta (gold standard); TTE (gradient, associated lesions); echocardiographic screening of first-degree relatives for bicuspid aortic valve and aortopathy

Special Populations

🀰
Pregnancy
Physiological changes Blood volume increases 30–50%; cardiac output increases 30–50%; heart rate increases 10–20 bpm; systolic flow murmur common (ejection systolic, pulmonary area); S3 may be physiological; peripheral oedema common without pathology.
Pathological murmurs New diastolic murmurs, pansystolic murmurs, or grade β‰₯3 systolic murmurs in pregnancy require echocardiography. New symptoms (exertional dyspnoea disproportionate to gestation, orthopnoea, palpitations, syncope) warrant cardiology review.
High-risk conditions Severe AS, severe MS, Marfan syndrome with aortic root dilation (>40 mm), pulmonary arterial hypertension, mechanical prosthetic valves, peripartum cardiomyopathy β€” require multidisciplinary pregnancy heart team management at a tertiary centre.
Modified WHO (mWHO) classification guides risk assessment for pregnant women with cardiac disease. mWHO Class IV (severe systemic ventricular dysfunction, severe MS, severe AS, pulmonary hypertension) β€” pregnancy contraindicated.
πŸ‘Ά
Paediatrics
Normal paediatric heart sounds Heart rate varies with age (neonates 120–160 bpm, infants 100–150, children 70–120). S3 is commonly heard in healthy children. Innocent (flow) murmurs are extremely common (up to 80% of children) β€” these are systolic, short, musical, loudest at the left sternal edge, vary with position, and have no associated signs.
Red flags in paediatric cardiac assessment Cyanosis (especially differential cyanosis β€” transposition of the great arteries with PDA); failure to thrive; feeding difficulty with diaphoresis; absent femoral pulses (coarctation); fixed widely split S2 (ASD); continuous murmur (PDA); harsh pansystolic murmur with thrill (VSD).
Rheumatic fever Remains a significant cause of acquired heart disease in Australian children, particularly in Indigenous communities. Jones criteria (revised) require evidence of preceding streptococcal infection plus either 2 major or 1 major + 2 minor criteria. Echo screening programmes exist in high-prevalence regions (Northern Territory, Far North Queensland).
All neonates should be screened for critical congenital heart disease (CCHD) using pulse oximetry at 24–48 hours of life. Pre-ductal (right hand) and post-ductal (either foot) saturations should both be β‰₯95% with ≀3% difference.
πŸ‘΄
Elderly (β‰₯75 years)
Atypical ACS presentation Up to 30% of elderly ACS patients present without chest pain β€” dyspnoea, fatigue, syncope, confusion, nausea, or back pain may be the predominant symptoms. Maintain a low threshold for 12-lead ECG and troponin testing.
Degenerative valvular disease Calcific aortic stenosis is the most common valvular lesion in the elderly; the murmur may be soft or inaudible due to reduced cardiac output ("silent AS"). Any unexplained exertional dyspnoea or syncope warrants echocardiography. Transcatheter aortic valve implantation (TAVI) is available in major Australian centres.
Atrial fibrillation Prevalence increases significantly with age (5–10% in those β‰₯65 years). Irregularly irregular pulse on examination. CHAβ‚‚DSβ‚‚-VASc score guides anticoagulation. Beers criteria caution against anticholinergic load contributing to AF.
Orthostatic hypotension is common in the elderly due to polypharmacy, autonomic dysfunction, and dehydration. Measure lying and standing blood pressure (after 1 and 3 minutes) in any patient reporting dizziness or falls. A drop of β‰₯20 mmHg systolic or β‰₯10 mmHg diastolic is diagnostic.
🫘
Renal Impairment
Fluid overload assessment Patients with CKD (particularly stage 4–5 and those on dialysis) frequently develop volume overload. Elevated JVP, bilateral crackles, ascites, and peripheral oedema are common. Assess dry weight versus current weight. Pericarditis may develop in uraemic patients (requires urgent dialysis).
Cardiovascular screening CKD is an independent risk factor for CVD. Accelerated atherosclerosis, vascular calcification, and cardiomyopathy are prevalent. Annual cardiovascular assessment recommended. Cardiac troponin is frequently chronically elevated in CKD β€” use delta troponin (change from baseline) rather than absolute values for ACS diagnosis.
Echocardiographic assessment of volume status is challenging in dialysis patients. IVC collapsibility index, lung ultrasound B-lines, and bioimpedance spectroscopy are adjunctive tools used in nephrology centres.
🫁
Hepatic Impairment
Cirrhotic cardiomyopathy Characterised by blunted contractile response to stress, prolonged QT interval, and diastolic dysfunction in the setting of cirrhosis. Clinically evident when patients develop ascites refractory to diuretics, hepatorenal syndrome, or cardiac decompensation during TIPS or liver transplantation.
Hepatojugular reflux Particularly useful in patients with coexisting liver disease and suspected right heart failure. Sustained pressure over the RUQ for >15 seconds that causes a sustained JVP rise of β‰₯4 cm is a positive test and supports right heart dysfunction rather than isolated liver disease causing ascites.
NT-proBNP may be cleared hepatically; BNP may be more reliable for heart failure assessment in patients with significant liver dysfunction. Albumin-corrected calcium should be assessed in patients on cardiac medications affecting calcium metabolism.
πŸ›‘οΈ
Immunocompromised
Infective endocarditis risk Immunocompromised patients (HIV with low CD4 count, transplant recipients on immunosuppression, patients on biologics) may present with atypical endocarditis β€” culture-negative, indolent courses, unusual organisms (Coxiella, Bartonella, fungi). Maintain a high index of suspicion with unexplained fever and new murmur.
Cardiac transplant recipients Annual coronary angiography or CT coronary angiography recommended due to cardiac allograft vasculopathy (CAV) β€” an accelerated form of coronary disease. Rejection surveillance may involve endomyocardial biopsy. Hypertension is common due to calcineurin inhibitors.
HIV-positive patients have increased cardiovascular risk (accelerated atherosclerosis, metabolic syndrome from antiretroviral therapy). Regular cardiovascular risk assessment is recommended as per Australian HIV guidelines (ASHM).

Investigations

Investigations should be guided by the clinical findings from the history and examination. The following summarises the key investigations available in Australian clinical practice, including MBS item numbers where applicable.

Essential 12-Lead Electrocardiogram (ECG) MBS Item 11100. Available in all Australian EDs, GP practices (with equipment), and hospitals.

Aboriginal and Torres Strait Islander Health Considerations

Aboriginal and Torres Strait Islander Health

Cardiovascular disease is the leading contributor to the gap in life expectancy between Aboriginal and Torres Strait Islander Australians and non-Indigenous Australians. Indigenous Australians experience CVD at 1.7 times the rate of the general population and are significantly more likely to die from cardiovascular events before the age of 65. Rheumatic heart disease (RHD), largely eliminated from non-Indigenous Australia, remains endemic in remote Northern Territory, Western Australian, and Far North Queensland communities at rates among the highest in the world.

Rheumatic Heart Disease
RHD affects Indigenous Australians at 68 times the rate of non-Indigenous Australians, predominantly in children aged 5–14 years. Acute rheumatic fever (ARF) is a notifiable disease in the NT, WA, QLD, SA, and NSW. The RHD Endgame Strategy (2020) aims to eliminate ARF and RHD in Australia by 2031. All patients with suspected ARF or RHD should be referred to the RHDAustralia register and managed in collaboration with the local RHD control programme.
Rural & Remote Access
Access to specialist cardiology services (echocardiography, stress testing, angiography) is limited in remote communities. The Royal Flying Doctor Service (RFDS) provides emergency retrieval and some outpatient clinics. Telehealth echocardiography and store-and-forward ECG interpretation are expanding through NT Cardiac and state-based programmes. Patients requiring cardiac surgery or interventional procedures must travel to tertiary centres (Royal Darwin Hospital, Fiona Stanley Hospital, Princess Alexandra Hospital, etc.), which can be culturally and logistically challenging.
Cardiovascular Risk Assessment
The AusCVDRisk calculator (National Vascular Disease Prevention Alliance) should be used for cardiovascular risk assessment in Indigenous Australians aged 30–74 years (note: lower age threshold than the general population recommendation of 45 years). Indigenous Australians qualify for a cardiovascular risk assessment from age 30 due to the earlier onset of CVD. Communicate risk using culturally appropriate tools and visual aids developed by organisations such as Menzies School of Health Research.
Social Determinants of Health
Cardiovascular disease burden in Indigenous communities is driven by social determinants including housing overcrowding (facilitating streptococcal transmission for RHD), food insecurity (limited access to affordable fresh food in remote communities β€” "healthy food basket" costs 2–3 times more), tobacco use (Indigenous smoking rate 37% vs 10% non-Indigenous), and barriers to healthcare access. Culturally safe care requires engagement with Aboriginal and Torres Strait Islander health workers, acknowledgement of intergenerational trauma, and respect for cultural practices around illness, family, and Country.
Screening & Prevention Programmes
Endocarditis: Prophylactic antibiotics before dental procedures are indicated for Indigenous Australians with RHD and prosthetic valves (as per the Australian RHD guidelines). Diabetes: The rate of type 2 diabetes in Indigenous Australians is 3.5 times higher than non-Indigenous Australians β€” cardiovascular screening should include annual HbA1c, lipid profile, renal function, and ABPI in patients with diabetes >5 years. Heart failure screening: Echocardiographic screening programmes for RHD in high-prevalence school-age children exist in the NT and QLD (register with RHDAustralia).
Culturally Safe Communication
Use clear, jargon-free language with visual aids. Be aware that some communities prefer gender-concordant clinicians for chest examination. Allow time for yarning and relationship-building before clinical assessment. Engage Aboriginal health workers/practitioners as cultural brokers and clinical partners. Recognise the concept of "sorry business" (bereavement) and its impact on appointment attendance and health engagement. Interpretation services are available through Aboriginal Interpreter Service (NT), Yalu Marringathun DhΓ€palalay (QLD), and equivalent services in other states.

Cultural safety
Engagement with Aboriginal Community Controlled Health Organisations (ACCHOs) is essential. Cultural safety training for non-Indigenous clinicians, use of Aboriginal Health Workers and Liaison Officers, and incorporation of traditional healing practices alongside Western medicine improve treatment adherence and outcomes. Avoidance of eye contact, respect for gender-sensitive examination practices, and understanding of sorry business protocols are critical elements of culturally safe care.
Medication adherence
Complex DMARD regimens with frequent monitoring requirements present adherence challenges. Long-acting depot injections (e.g., methotrexate SC) may improve adherence compared to oral regimens. Community pharmacy partnerships through the Indigenous Pharmacy Programmes improve medication management.
Specific conditions
Rheumatic heart disease (RHD) requires secondary prophylaxis with benzathine penicillin G (BPG) 1.2 MU IM every 3–4 weeks for a minimum of 10 years or until age 21 (whichever is longer). RHD registers (e.g., NT RHD Register) facilitate recall and follow-up. The Australian RHD Endgame Strategy targets elimination by 2031.
Referral pathways
Referral through ACCHOs and Aboriginal Hospital Liaison Officers (AHLOs) improves engagement. The Specialist Outreach Assistance Programme provides funded specialist visits to remote communities. NT, WA, and QLD have specific rheumatology outreach programmes targeting Indigenous communities.
