Answer 31

31.  Choice A is the correct answer.  Dilated cardiomyopathy causes systolic dysfunction and systolic murmur.  Hypertrophic and Restrictive Cardiomyopathy are causes diastolic dysfunction. Think of dilated cardiomyopathy as having extra large that can fit more blood in them.  The problem is the blood gets into the ventricle and cannot be pumped out because it is much larger than the atria.  The most common cause of dilated cardiomyopathy is idiopathic.  Other causes of dilated cardiomyopathy are genetic, thyrotoxicosis, starvation, post partum, sarcoidosis, hemochromatosis, radiation, thiamine deficiency, alcohol, catecholamine induced, infectious, and radiation.   Treatment of dilated cardiomyopathy is similar to heart failure which involves increasing preload and decreasing after load.  ACE inhibitors and beta blockers are ideal for the appropriate patients.
