Verily in the body there is a piece of meat. If it healthy , the whole body will be healthy. If it is diseased the whole body will be diseased. Verily it is the heart ( Prophet Muhammad pbuh )
Definition of Heart Failure ( 1950s ) A state in which the heart fails to maintain an adequate circulation for the needs of the body despite a satisfactory filling pressure
Definition of Heart Failure ( 1980s) A clinical syndrome caused by an abnormailty of the heart and recognised by a characteristic pattern of haemodynamic, renal, neural and hormonal responses
Definition of Heart Failure (Packer 1998) A complex clinical syndrome characterized by abnormalities of left ventricular function and neurohumoral regulation which are accompanied by effort intolerance, fluid retention and reduced longevity

Heart Failure Aetiology( Common ) • Hypertension • Ischaemic Heart Disease • Valvular Heart Disease • LVH • Diabetes
Heart Failure Aetiology( Less Common and easily forgotten ) • Thyrotoxicosis • Dilated Cardiomyopathy ( non ischaemic; viral, post traumatic ) • Post partum cardiomyopathy • Beriberi cardiomyopathy

Symptoms • Fatique • Reduce effort tolerance • Dyspnoea • Orthopnea • PND • Cough esp. nocturnal • Symptoms of poor circulation
Symptoms • Palpitation • Angina • Giddiness/ syncope • Weight loss • Muscle wasting • Peripheral edema • ascites
Symptoms • Epigastric / right hypochondriac pain • Nausea • Anorexia • Facial engorgement • Depression
Signs • Exhausted , ill looking patient • Cool hands and feet • Peripheral cyanosis • Raised JVP • Low volume pulse • Resting tachycardia • Displaced apex
Signs • RV heave • S3 gallop • Hepatomegaly ( pulsatile ) • Ascites • Ankle edema • Bilateral crepitations • Pleural effusion
Important Reminder When ever a patient presents with decompensated heart failure, always ask yourself TWO questions What is the underlying aetiology ?? What is the precipitating factor to cause the decompensation ??
Heart Failure Precipitating/ aggravating factors • Cardiac causes – MI,arrhythmia • Non cardiac causes – anaemia, accelerated hypertension, pulmonary embolism, pneumonia, acute renal failure • Treatment related – poor compliance, NSAIDs, steroids, beta blockers if used wrongly • Salt and liquorice intake including TCM
Differential Diagnosis Pulmonary edema due to • Mitral stenosis • Atrial myxoma • Low LA pressures due to sepsis, noxious gas inhalation, severe myxedema, hypoalbuminaemia, head injury, SAH , ARDS
Differential Diagnosis RV failure • Constrictive pericarditis • SVC obstruction • Malignant ascites
Investigations • ECG - to look for aetiology and precipitant • CXR – changes can precede signs • Urea and electrolytes – renal precipitant • FBC – anaemia and infection • BNP – if the cause of acute breathlessness is unclear from physical findings • ECHO – to quantify type and contributing lesions • Thyroid function – mandatory if A Fib is present

Establishing the diagnosis of CHF • Is LV ejection fraction preserved or reduced ? • Is the LV structure normal or abnormal ? • Other structural abnormalities ?
Establishing the diagnosis of HFSystolic vs diastolic dysfunction Diagnosis of diastolic HF (up to 40%) Abnormal LV EF < 50%
Heart Failure - Classification • Acute or chronic or acute on chronic • Low- output or high- output • Left – sided or right- sided or biventricular • Systolic ( HFrEF ) or diastolic ( HFpEF )
