Cardiology Flashcards
murmur of mitral stenosis
low-pitched, rumbling, diastolic with loud S1 and opening snap
causes of mitral stenosis
rheumatic fever, atrial myxoma
murmur of mitral valve regurgitation
loud holosystolic murmur best heard at the apex that radiates to the base
murmur of mitral valve prolapse
early to midsystolic click with with late systolic murmur best heard at left lateral heart border
causes of acute mitral regurgitation
endocarditis, AMI, trauma
murmur of aortic stenosis
crescendo-decrescendo systolic murmur radiating to the neck
causes of aortic stenosis
calcific valve degeneration, bicuspid aortic valve
murmur of aortic regurgitation
high-pitched, blowing diastolic murmur best heard at left sternal border, decreases with valvsalva
causes of acute aortic regurgitation
endocarditis, aortic dissection
hypertrophic cardiomyopathy murmur
harsh systolic ejection murmur that increases with standing/Valsalva and decreases with squatting and handgrip
signs associated with aortic regurgitation
water hammer pulse, de Musset sign (head bobbing with pulse), Quincke sign (pulsating nailbed), wide pulse pressure, Muller sign (visible pulsations of uvula)
symptoms of mitral valve prolapse
asymptomatic or may have dyspnea, palpitations, nonexertional chest pain, fatigue
most common cause of aortic regurgitation
endocarditis
symptoms of aortic regurgitation
exertional dyspnea, angina, symptoms of heart failure
what is austin flint murmur
late diastolic murmur best heard at apex.
high intensity statins

moderate intensity statins
lovastatin 40-80 mg, pravastatin 40-80 mg, simvastatin 20-40 mg, atorvastatin 10-20 mg, rosuvastatin 5-10 mg
low-intensity statins

most common type of cardiomyopathy
dilated
most common cause of dilated cardiomyopathy (NOT in the setting of CAD)
idiopathic
most common infectious causes of dilated cardiomyopathy
Viruses (especially enteroviruses, coxsackie virus)
toxic causes of dilated cardiomyopathy
ETOH abuse, cocaine, anthracyclines (doxorubicin), radiation
metabolic causes of dilated cardiomyopathy
thyroid disorders, thiamine deficiency
less common infectious causes of dilated cardiomyopathy
postviral myocarditis, HIV, Lyme disease, Parvovirus B19, Chagas disease
echocardiogram findings of dilated cardiomyopathy
left ventricular dilation, thin ventricular walls, decreased ejection fraction, ventricular hypokinesis
hallmark PE finding for dilated cardiomyopathy
S3 gallop
Cause of S3 gallop
filling of a dilated ventricle
Agents for mortality reduction in dilated cardiomyopathy
ACE inhibitors/ARBs, beta blockers
