Cardio Flashcards
Which category of non ischemic cardiomyopathies makes up 90%?
Dilated
What are the 3 major categories of cardiomyopathies?
Dilated, hypertrophic, restrictive
…. cardiomyopathy is characterized by enlargement and dilatation of all four chambers of the heart.
dilated
Many of these cases have no known etiology and are referred to as idiopathic cardiomyopathy.
dilated
The most common cause of non-ischemic dilated cardiomyopathy in the U.S. is
chronic alcoholism
(Cardiomyopathy) nonspecific cellular abnormalities, including variations in myocyte size, myocyte vacuolation, loss of myofibrillar material and/ or fibrosis.
Dilated
Cardiomyopathy characterized by myocardial hypertrophy, abnormal diastolic filling and in about one third of cases, intermittent ventricular outflow obstruction
Hypertrophic
(cardiomyopathy) Microscopically, the heart demonstrates hypertrophy of myocardial fibers (which also have prominent dark nuclei) along with interstitial
fibrosis.
hypertrophic cardiomyopathy (HCM)
The heart becomes thick-walled, heavy, and hyper-contracting
Hypertrophic cardiomyopathy
The essential feature of …. is massive myocardial hypertrophy without ventricular dilation.
HCM
A classic appearance of…is the disproportionate thickening of the ventricular septum as compared with the free wall of the ventricle.
HCM (hypertrophic cardiomyopathy)
Marked left ventricular hypertrophy, with bulging of a very large interventricular septum into the left ventricular chamber.
HCM
In …. cardiomyopathy, the myocardium is usually infiltrated with abnormal tissue that results in impaired ventricular wall motion with abnormal ventricular wall contraction and relaxation.
restrictive
The most common causes of restrictive cardiomyopathy are …. (2)
amyloidosis and hemochromatosis.
