heart failure Flashcards
symptoms of heart failure
shortness of breath wheezing and coughing ankle swelling reduced exercise tolerance fatigue
reduced vs preserved ejection fraction
reduced - left ventricle loses ability to contract normally 40% reduction in ejection fraction
perseved - loses ability to relax - EF normal or mildly reduced
signs of heart failure
elevated venous jugular pressure, pulmonary crackles and pulmonary oedema
aims of heart failure treatment
reduce mortality
reduce symptoms
increase exercise tolerance
daily weighing
an increase of 1.5kg - 2.0kg in 2 days should be reported to heart failure specialist
salt and fluid intake advice
only restrict if these are high
salt intake of less than 6g a day
avoid salt substitutes containing potassium
salt and fluid intake advice
only restrict if these are high
salt intake of less than 6g a day
avoid salt substitutes containing potassium - reduce risk of hyper
What is diluteinal hyponatremia and how is it managed
the bodies consumption of water exceeds the kidneys ability to eliminate water- only limit water intake
drug treatment
ace inhibitor and beta blocker
OR hydralazine and nitrate and beta blocker to reduce mortality
ARB can be used in place of ACE
diuretics
clinical judgement used to decide which to start first and second drug only started when 1st drug is stable
aldosterone antagonist e.g. epelerone or spiralactone
what drugs should be avoided in patients with reduced EF
rate limiting CCBs, short acting dihyropryridines as they reduce cardiac contractility
what is the advice on use of thiazide diuretics in HF
only of benefit for patients with mild fluid retention and eGFR od greater than 30ml/min/1.73m2
when can anticoagulation be considered
patients in sinus rhythm with a
history of vte
left ventricular anaersym
inter cardiac thrombus
monitoring of ACE/ARB and beta blockers
ACE - ARBs, aldosterone antagonists serum potassium 1/2 weeks after starting and at each dose increment
then every 3 months, then 6 months and if acutely unwell
BB - heart rate, blood pressure, symptom control at start
How is management of HF adjusted in CKD
lower dose ACE ARB, aldosterone antagonist and digoxin
