A 65-year-old man was found to have a 5-cm pulsatile mass in his abdomen during a routine physical examination. Angiography reveals a marked dilation in his aorta distal to the renal arteries. Which of the following is the most likely cause of this aneurysm?

40. A 65-year-old man develops intense crushing substernal, chest pain that is not relieved by nitroglycerin. The ECG shows ST-segment elevation and abnormal Q waves. His condition rapidly worsens and he dies 2 days later. At autopsy a 2.5 cm2 necrotic area is found that involves the anterior left ventricle. What is the most likely cause of this patient's myocardial infarction?
A:Fibrinoid necrosis of main trunk of left coronary artery B:Vasospasm of the right coronary artery C:Thrombosis of the anterior descending branch of the left coronary artery D:Severe stenosis of all three main branches of coronary artery without thrombosis E:Complete occlusion of the left circumflex coronary artery 4.
A 57-year-old man has had blood pressure measurements in the range of 160/95 to 180/110 mm Hg for many years. He has taken no medications. A renal scan reveals kidneys of normal size for age. These findings with benign nephrosclerosis are most likely to occur with which of the following vascular changes?
A:Monckeberg's medial calcific sclerosis B:Hyaline arteriolosclerosis C:Arterial mural thrombosis D:Hyperplastic arteriolosclerosis E:Complex calcified atherosclerosis 5.
A 51-year-old man has the sudden onset of substernal chest pain which radiates to his left arm and neck. He becomes light-headed and diaphoretic over the next 8 hours. He goes to the emergency room. On examination he is afebrile but has a heart rate of 96/minute with an irregular rhythm. Laboratory studies show an increased serum troponin I. Which of the following features would be most prominent by histopathologic examination of his myocardium at this point in time?
A:Collagen deposition B:Macrophage infiltration C: Neutrophilic infiltration D:Coagulative Necrosis E: Capillary proliferation 6.
