Why is intermittent claudication clinically important in cardiovascular disease assessment?

• A. Indicates peripheral arterial disease and increased prevalence of coronary artery disease.
• B. Indicates aortic aneurysm.
• C. Indicates pulmonary embolism.
• D. Indicates liver disease.

Answer: (A)

Intermittent claudication reflects peripheral arterial disease, which is a manifestation of systemic atherosclerosis. When the leg muscles ache or fatigue with walking due to insufficient blood flow, it signals that arteries throughout the body are affected by atherosclerotic narrowing. Because atherosclerosis tends to involve multiple vascular beds, patients with peripheral arterial disease have a higher likelihood of concomitant coronary artery disease. That makes this symptom clinically important: it identifies patients at increased risk for heart events and prompts thorough cardiovascular risk assessment and management, including risk factor modification, antiplatelet therapy when appropriate, and consideration of further evaluation for coronary disease. The other conditions don’t fit this symptom pattern. Aortic aneurysm presents with different signs like a pulsatile abdominal mass or back pain, pulmonary embolism with sudden chest pain and shortness of breath, and liver disease with liver-specific signs and lab abnormalities.
