Which of the following atherosclerotic disease manifestations is accurately matched_____________?
Show answer Hide answer
Answer: D. All of the above
Explanation
Atherosclerosis manifests in the aorta as aneurysms and thromboembolism, damaging large elastic vessel walls. Coronary artery atherosclerosis leads to myocardial infarction and ischemic heart disease through luminal narrowing. Lower extremity involvement produces intermittent claudication and peripheral gangrene from chronic tissue ischemia. Atherosclerosis is a systemic inflammatory disease characterized by lipid-rich plaque buildup in arterial walls. Plaque rupture and subsequent thrombosis are the primary triggers for acute ischemic vascular events. Risk factors include hypertension, hyperlipidemia, diabetes mellitus, smoking, and advanced age.
Cardiovascular disease remains a leading cause of morbidity and mortality in industrialized nations worldwide. Early detection and lifestyle modifications can significantly slow the progression of atherosclerotic vascular disease. Surgical interventions like bypass grafts and stent placements restore blood flow to ischemic tissue beds. Aortic atherosclerosis causes destructive aneurysms and thromboembolism rather than isolated peripheral symptoms. Coronary atherosclerosis directly causes myocardial infarction and ischemic heart disease syndromes. Lower extremity atherosclerosis restricts arterial blood flow, causing painful claudication and eventual tissue gangrene.
