What is High output Heart Failure?
Heart is working normally but the needs of the body are higher than what the heart can supply
What Conditions cause high output HF?
Hyperthyroidism
Anaemia
Paget’s disease
AV malformation
Frank Starling Mechanism
Preload
Pump Failure
Chronic excessive afterload
Examples of Increased Preload
Mitral regurgitation
Fluid overload
Examples of Pump Failure
IHD Cardiomyopathy Constrictive pericarditis Cardiac tamponade Heart block Post-MI AF Negatively inotropic drugs: verapamil, diltiazem
Examples of chronic excessive afterload
Hypertension
Aortic Stenosis
Investigations
U: Urinalysis B: U+Es, Creatinine, FBC, TFTs, LFTs, glucose, lipids, BNP E: 12 lead ECG I: Chest X Ray, Echocardiography S: Peak flow, spirometry
HF findings on CXR
Alveolar Oedema Prominent Upper Lobe Vessels Bat's wings Kerley B lines Pleural effusions
How to confirm the diagnosis of HF?
Echocardiography
NYHA I
No limitation, physical exercise does not cause symptoms
NYHA II
Slight limitation of physical activity
NYHA III
Marked limitation of physical activity
NYHA IV
Unable to carry out any physical activity without discomfort
Conservative management of HF
Risk Factor Management Education Decrease salt Decrease weight Restrict alcohol Restrict fluid intake Pneumococcal and annual influenza vaccination
Drugs for HF w/ Reduced EF
ACE inhibitors
Beta Blockers
Diuretics if fluid overloaded
Drugs for HF w/ Preserved EF
Diuretics
No specific treatment
Examples of Loop diuretics
Furosemide
Bumetanide
