CVS drugs 2 Flashcards
Heart failure drugs?
Diuretics ACE-i beta blockers mineralocorticoid receptor antagonists digoxin vasodilators
SEs of loop diuretics?
hypokalaemia, renal impairment
Indications of starting a K+ sparing diuretic in HF?
if K+ <3.2mmol/L, predisposition to arrhythmias, concurrent digoxin therapy, or preexisting
K+-losing conditions.
When to consider ACE-i in HF? major SE in HF?
in all those with left ventricular systolic dysfunction (LVSD)
raised K+
beta blocker usage in HF?
Use with caution: ‘start
low and go slow’; if in doubt seek specialist advice fi rst; wait ≥2weeks between
each dose increment.
Example of mineralcorticoid?
spironolactone
eplerenone
SE of hydralazine? Use in HF?
Drug induced lupus
should be used if intolerant of ACE-i and ARBS as it reduces mortality. It also reduces mortality when added to standard therapy (including ACE-i) in black patients with heart failure
Mx of intractable HF?
Inpatient management may include:
• Minimal exertion; Na+ & fluid restriction (1.5L/24h PO).
• Metolazone (as above) and IV furosemide.
• Opiates and IV nitrates may relieve symptoms).
• Weigh daily. Do frequent U&E (beware low K+).
• Give DVT prophylaxis: heparin + TED stockings (p578).
Mx of rheumatic fever>
benzylpenicillin IV STAT, then phenoxymethylpencillin for 10 days) - if allergic to penicillin, give erythromycin or azithromycin for 10 days
Trigger of rheumatic fever? Dx?
Lancefi eld group A -haemolytic streptococci triggers rheumatic fever
2–4wks later - due to An antibody to the carbohydrate
cell wall of the streptococcus cross-reacts with valve tissue
Dx: use Jones’ criteria (2 major/ 1major+2minor)
Jones criteria use? major criteria? minor criteria?
in Dx of rheumatic fever
major: Carditis,
arthritis (a migratory, ‘flitting’ polyarthritis)
subcutaneous nodules (small, mobile, painless nodules on extensor surfaces of joints and spine)
erythema marginatum, Sydenham’s chorea - Unilateral or bilateral
involuntary semi-purposeful movements. May be preceded by emotional lability
and uncharacteristic behaviour.
Minor: fever, raised ESR/CRP, arrthralgia, prolonger PR interval, previous rheumatic fever
