Cardiac Failure
A syndrome caused by any abnormality of the heart that may be characterised by a set of haemodynamic,
neural, and endocrine abnormalities
LVF
Causes:
o IHD
o Hypertension
o Valve disease
o Myocardial disease
Consequences:
o Impaired pulmonary outflow
Congestion and oedema
o Reduced renal perfusion
Salt and water retention +
ATN
o Reduced CNS perfusion
(encephalopathy)
RVF
Causes:
o Left-sided heart failure
(Congestive)
o Chronic Lung Pathology - Cor
Pulmonale
Consequences:
o Portal, systemic and peripheral
congestion
o Tricuspid regurgitation
o Renal congestion (R > L)
Cardiomyopathy
Causes
Features
Hypertrophic
Inherited (50% AD)
Sporadic cases
Pathology - heavy muscular hypertrophy with poor
compliance
Often asymmetrical septal hypertrophy
Sequelae:
- Arrhythmias - AF
- LV outflow obstruction
- CHF
- Sudden deathYoung man
Syncope, FH of sudden death, Jerky pulse and double
apical impulse, Ejection systolic murmur (+/- mild mitral
murmur)
Dilated
Idiopathic
Four-chambered hypertrophy and dilatation
