Rationale 1: Renal failure would result from atherosclerotic changes in the renal artery.
Rationale 2: Gangrene may occur if atherosclerosis reduces blood flow to the extremities.
Rationale 3: Myocardial infarction results from atherosclerosis of the coronary arteries.
Rationale 4: Transient ischemic attacks may result from atherosclerosis of the cerebral vessels. Continued development of this atherosclerosis may result in stroke.
