myocardial infarction
myocardial ischemia
What can heart attacks lead to?
cardiomyopathies
atherosclerosis
arteriosclerosis
Which subtype of cardiomyopathy is seen in congestive heart failure when heart is weakened causing low stroke volume, ventricles enlarge due to higher volume of blood pumped in from the venous system in order to increase stroke volume and cardiac output, results in inability for heart to constrict
dilated cardiomyopathy (congestive cardiomyopathy)
hypertrophic cardiomyopathy
restrictive cardiomyopathy
Which cardiomyopathy subtype generally occurs after an MI leading to increase in muscle tissue around ventricles due to tissue damage and leads to lower stroke volume?
dilated cardiomyopathy (congestive cardiomyopathy)
hypertrophic cardiomyopathy
restrictive cardiomyopathy
Which cardiomyopathy subtype is a condition where the chambers of the heart become stiff over time. The heart is able to squeeze well, not able to relax. makes it harder for the heart to fill with blood. Usually caused by amyloidosis: an abnormal buildup of protein in organs and tissues.
