cardiomyopathy Flashcards
(54 cards)
group of diseases of the myocardium associated with cardiac dysfunction
cardiomyopathy
main types of cardiomyopathy
- dilated cardiomyopathy
- stress cardiomyopathy
- hypertrophic cardiomyopathy
- restrictive cardiomyopathy
dilated cardiomyopathy
systolic (pumping) problem, and dilated baggy ventricles
impaired contraction of one or both ventricles
reduced ejection fraction is less than ___
40%
most common etiologys of dilated cardiomyopathy
idiopathic,,most common
infectious myocarditis, coxsakie b
toxic causes; etoh, cocaine,
b1 deficiency
doxorubicin
dilated cardiomyopathy best test
echo
echo shows left ventrciular dilation, decreased ef <40%
clinical presentastion. of dilated cardiomyopathy
heart failure
left heart failure signs include, orthopnea,
right heart failure signs include, jvd, peripheral edema
lab tests in dilated cardiomyopathy
serum BNP, usually elevated
helpful to determine prognosis, and severity
physical exam for dilated cardiomyopathy will show an ___ gallop rhythm,
s3
peripheral edema, acites, jvd, crackles
pt comes in with complaints of diffculty breathing when walking, you note tachycardia on monitor, and in listeing to lungs you hear crackles, and see pedal edema, you decide to order an echo and you see left ventricular dilation and reduced ef at 35%. (1) what do you suspect? and (2) how will you treat this pt?
dilated cardiomyopathy, will tx using a combination of meds including
beta blocker, to reduce contractility (metoprolol)
ARNI- sacubitril-valsartan or ACE (pril)
spironolactione
diuretic, furosemide
also control contributin f factors
pt with dilated cardiomyopathy when to admit
with hypoxia, fluid overload, or pulmonary edema, that is not fixed in an outpt setting
stress cardiomyopathy is characeterized by a transient -______ dysfunction of the left ventricle, myocardial infarction, but is in _______of coronary artery diseas or in a plque rupture
systolic
absense
stress cardiomyopathy is also called _________ and ______
broken heart syndrome
and takomondo (octopus)
stress cardiomyopathy occurs after a major______ surge
catecholamine
(epinephrine and norepinephrine)
ecg in stress cardiomyopathy will show
st elevations similar to st elevation in mi
what other lab work is elevated in stress cardiomyopathy
cardiac enzymes, and bnp
what lab diagnostic is required in stress cardiomyopathy to exclude acute coronary syndrome due to similar symptoms
coronary angiography, needs to shows absense of a plaque ruptue or obstructive coronary disease
stress cardiomyopathy symptoms
acute substernal chest pain
dyspnea
syncope
frequently, a recent intense emotional or physcial stress, death of a loved one,
______ performed after acute coronary syndrome is ruled out via coronary angiography absense of plaque rupture or obstructive coronary disease in stress cardiomyopathy
echocardiogram
echocardiogram for stress cardiomyopathy (takotsubo syndrome) shows
transient systolic dysfunction
apical left ventricle ballooning
initial tx for stress cardiomyopathy
aspirin, nitroglycerin, beta blocker, heparin, pt comes in and appears like a heart attack
conservative and supportive care, is the mainstay treatment in most patients
a 80 year old pt with a recent loss of her husband complaint pf substernal chest pain, dyspnea, ecg highlights st elevations, and cardiac enzymes elevated troponin and bnp are elevated, what other diagnostic test will you perform
coronary angiograpohy, (CTA) first
if absense of plaque rupture then echo,
shows transient systolic dysfunction and left ventricle ballooning
stress cardiomyopathy is a type of _____ cardiomyopathy
dilated
who does stress cardiomyopathy predominantly affect
post menopausal women
