Case Presentations in Heart Failure Ivor L Gerber Cardiologist Auckland Heart Group Auckland City Hospital
Case 1 82 year old woman Longstanding hypertension Treatment for UTI Otherwise well Increasing shortness of breath Leg swelling Palpitations
Clinical exam Irregular rhythm, 110bpm BP 160/90mmHg Mild pitting oedema. No murmur. JVP +4cm. Bibasal crackles ECG Atrial fibrillation, LVH. Troponin Normal N-BNP 120 CXR Mild cardiomegaly Mild interstitial oedema
Diagnosis – “ Heart failure ”
Diagnosis – “ Heart failure ” Clinical assessment Supported by investigations so far
What is the likely cause? Common things occur commonly Hypertension LVH, LV diastolic dysfunction, left atrial dilatation. Coronary artery disease LV systolic / diastolic dysfunction Valve disease LV systolic / diastolic impairment. Precipitating factors Recent UTI Atrial fibrillation Check thyroid function
What additional investigation(s) are needed? Echocardiogram LV size and systolic function - often normal LVEF LVH. LV diastolic function. LA size Valves Right heart
What additional investigation(s) are needed? Echocardiogram LV size and systolic function - often normal LVEF LVH. LV diastolic function. LA size Valves Right heart 24 hour holter monitor After rate control Exercise test Consider after acute factors managed
Treatment General Diuresis Rate control of the atrial fibrillation Ensure the UTI is controlled Optimise blood pressure Specific Depend on other results Rate vs rhythm control (LA size) Possible coronary artery disease
Case 2 24 year old man No past history of note Physical job Non-smoker Minimal alcohol Tires easily, short of breath on exertion
Clinical exam Regular rhythm 110bpm BP 95/60 mmHg Multiple murmurs No pitting oedema. JVP angle of jaw. Clear chest ECG Sinus tachycardia, LVH N-BNP 1120 CXR Moderate cardiomegaly Pulmonary oedema
Diagnosis Heart failure What is the likely cause? Common things occur commonly Valve disease – LV and/or RV impairment. Hypertension – LV diastolic dysfunction +/- atrial fibrillation Coronary artery disease – LV systolic/diastolic dysfunction What additional investigation(s) are needed? Echocardiogram Treatment General Specific
Treatment General Diuresis ACE inhibitor / ARB Beta blocker Specific Valve replacement
Heart Failure The diagnosis heralds the beginning, not the end, of the medical journey Clinical diagnosis supported by investigations Specific management depending on the cause High mortality, especially if not assessed and managed properly
Diagnosis “ Heart failure ” What is the likely cause? Always consider underlying cause and precipitating factors What investigation(s) are needed? Confirm diagnosis Mechanism – guides management Determine severity / prognosis Treatment
