265
Investigations for suspected heart failure?
N-terminal pro-B-rype natriuretic peptide level (NT-proBNP): if over 2000 2 week urgent referral, between 400 and 2000 6 week referral, less than 400=HF unlikely
Arrange 12 lead ecg
Consider other tests
266
What things may lead to increased BNP?
HF, age over 70, left ventricular hypertrophy, RV overload, hypoxia, pulmonary hypertension, PE, CKD (less than 60ml/min eGFR), sepsis, COPD, diabetes mellitus, cirrhosis

General: symptom report, monitor weight at home, avoid excessive salt, severe symptomatic should limit fluid intake (less than 1.5-2L/day), smoking cessation, drink safely, regular low intensity physical exercise if stable HF, maintain healthy weight
PEF: loop diuretic -up to 80mg furosemide
REF: loop diuretic, ACEi and beta blocker (start one at a time). Consider if antiplatelet and/or statin therapy required. Influenza and pneumococcal vaccine
