Statins reduce cardiovascular risk in atherosclerosis primarily through which mechanism?
From: Atherosclerosis & HypertensionCorrect answer: B. Statins inhibit HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis, lowering circulating LDL and slowing atherosclerotic progression.Subendocardial infarction preferentially affects which region of the ventricular wall, and why?
From: Ischemic Heart Disease & Heart FailureCorrect answer: D. The subendocardium is the last region to be perfused and the first to be compromised during reduced coronary flow, making it particularly susceptible to ischemic injury even without complete occlusion.Chronic rheumatic heart disease most characteristically affects which valve?
From: Valvular Disease & CardiomyopathiesCorrect answer: D. The mitral valve is by far the most commonly and severely affected valve in chronic rheumatic heart disease, often developing characteristic "fish-mouth" stenosis over time.Which congenital heart defect is most commonly associated with Down syndrome?
From: Vasculitis & Congenital Heart DiseaseCorrect answer: A. Endocardial cushion defects, including complete AV septal defects, are strongly associated with trisomy 21 and are among the most common congenital heart defects seen in Down syndrome patients.
