Cardiac-cardiomyopathy Flashcards
what type of cardomyopathy
“dilation of all 4 chambers of the heart”
dilated cardiomyopathy
what is the most common type of cardiomyopathy?
dilated cardiomyopathy
what type of dysfunction does dilated cardiomyopathy result in?
systolic dysfunction
what are the complications associated with dilated cardiomyopathy
biventricular CHF
mitral & tricuspid regurg
arrhythmia
what is the most common agent involved in myocarditis that could lead to dilated cardiomyopathy
coxsacki A or B
what characterizes coxsacki myocarditis? and what are the signs/symptoms
characterized by lymphocytic infiltrate in the myocardium
results in chest pain, arrhythmia with sudden death of HF
if you don’t die, the late complication is dilated cardiomyopathy
what 2 drugs can cause dilated cardiomyopathy
cocaine
doxorubicin
what cardiomyopathy
“massive hypertrophy of L. ventricle leading to diastolic dysfunction”
hypertrophic cardiomyopathy
what is the most common cause of hypertrophic cardiomyopathy
genetic mutation in sarcomere proteins (usually auto dom)
what are the 3 clinical features associated with hypertrophic cardiomyopathy
- decreased cardiac output
- sudden death due to ventricular hypertrophy
- syncope with exercise
what is the most common cause of sudden death in young athletes?
due to ventricular arrhythmias with hypertrophic cardiomyopathy
what causes the syncope with exercise seen in ppl with hypertrophic cardiomyopathy
subaortic hypertrophy of the ventricular septum results in functional aortic stenosis
when is this biopsy seen:
“myofiber hypertrophy with disarray”
in hypertrophic cardiomyopathy
what cardiomyopathy
“decreased compliance of the ventricular endomyocardium that restricts filling during diastole”
restrictive cardiomyopathy
what disease:
“dense layer of fibrosis and elastic tissue in the endocardium that leads to restrictive cardiomyopathy”
what population is this disease seen in?
endocardial fibroelastosis
