heart failure Flashcards
what is HF
heart cant pump enough blood to meet metabolic demand, = decreased cardiac output
what is EF
ejection fraction = how much blood ventricle pumps out in contraction
HFw/REF
heart failure with reduced ejection fraction <40% ef means left ventricle impaired contraction
hfw/pEF
hf with preservesd ef - impairedleft ventricular relaxation w/ evidence diastolic function
normal EF
50-70%
ef calc
total amount ejected/ total blood in ventricle x 100
symptoms and risk
pink tinge cough froth, dyspnea , swollen ankle and legs , fatigue reduce exercise tolerance
DM THYROID MI , AF HTN
risk: FAILURE F= atty heart valve, arrhythmia, infarction, uncontrolled htn ,recreational drugs, evaders
diagnosis biomarker
NT pro BNP, ecg ,cxr - large heart? pulmonary crackles?

classification of HF
NYHA fuunctipnal classification defines progression Hf according to severity symptoms linked to physical activity
stable/ chronic HF
symptoms unchanged 1+ months
Tx ment algorithm LVHF <EF 40%
1)congestion? Does patient need diuretic (breathlessness and edema)
loop preferred (bumetanide, furosemide, torosemide) or
tzd (only if mild edema and egfr >30)
2) improve survival?1st line : acei/arbs +beta blocker
beta blocker licensed (candersartan valsartan) beta blocker (bisoprolol, carvedilol all stages) if mild mod stable hf age 70+ then nebivolol
(MAKE SURE TITRATE BOTH TO MAX TOLERATED DOSE)
3)patient not imPROVE add aldosterone antagonist (spiranoactone or eplerenone) to acei/arb +beta blocker
NEXT STAGES BELOW UNDER SPECIALIST
4) If patient cant tolerate acei/arb in 1st line give hydralazine and nitrate - esp in carribean and African
5) if EF <35% give sacubitirl / valsartan (entresto)
6) intensification if with standard treatment add on Ivrabradine if in sinus rhythm HR >70 BPM and ef <35- add ivrabradine
or add digoxin (in worsening or severe hF - does not reduced mortality
other options with specialist- implantable defibrillator implant or resynchronisation therapy
monitoring in HF
acei/arb and AA : K+ and Na+ renal function and bp
1-2 weeks before start and each titration once target max reach monitor every 3 months and then every 6 months (and in acute illness)
BB- hr, bp , and symptom control at intitiation and titration
ckd- lower dose and slower titration of ace, aa, and digoxin
med to avoid HF
nsaid - nephrotoxic, corticosteroid (low dose- short period) , antacid high na+, soluble analgesic, rate limit ccb avoid and short acting ccb (i.e nifedipine nicardipine diltiazem or verapamil), ANTIARRYTHMIC i.e fleicainde and dronedarone, pioglitazone
