Aortic aneurysms are often asymptomatic. However, in a dissecting aortic aneurysm , symptoms are often described as tearing or ripping in the chest, back, or abdomen.
Answer to Question 2
ANS: A
Blockage in the right coronary artery (RCA) results in damage to the posterior/inferior area of the heart. The left main coronary artery (LCA) branches off to the left anterior descending artery (LAD) and the left circumflex artery (LCX). A highly stenotic LCA or proximal LAD can cause significant heart damage and is often termed the widow maker. Blockage in the LAD results in damage to the anterior portion of the heart. Blockage in the circumflex branch artery (CFX) results in damage to the posterior and lateral areas.
