Answer to Pathology MCQ 485

The Correct option is D


Ischemia refers to a lack of oxygen due to inadequate perfusion. Ischemic heart disease is a condition of diverse etiologies, all having in common an imbalance between oxygen supply and demand.

When all age groups are considered, ischemic heart disease is the most common cause of death not only in men but also in women. Approximately 25 percent of patients who survive acute myocardial infarction may not reach medical attention, and these patients carry the same adverse prognosis as those who present with the classic clinical syndrome. Sudden death may be unheralded and is a common presenting manifestation of ischemic heart disease. Patients can also present with cardiomegaly and heart failure secondary to ischemic damage of the left ventricular myocardium that caused no symptoms prior to the development of heart failure; this condition is referred to as ischemic cardiomyopathy. In contrast to the asymptomatic phase of ischemic heart disease, the symptomatic phase is characterized by chest discomfort due to either angina pectoris or acute myocardial infarction.
