Claudication: Exercise Vs. Endoluminal Revascularization: What Is Intermittent Claudication

Intermittent claudication is pain, cramps, heaviness, fatigue, or other equivalent symptoms involving the muscle groups of the legs.  It typically occurs with walking or stair-climbing, is reproducible, and is relieved with rest.  It is cause by reduced blood flow to the muscles of the buttocks, thighs, and calfs during walking, usually caused by atherosclerotic blockages. The condition is present in up to 30% of older individuals. Other conditions often present in people with intermittent claudication include atherosclerosis involving the coronary artery arteries, carotid arteries in the neck, or other arteries. Risk factors for the development of atherosclerotic blockages include smoking, high blood pressure, high cholesterol, high-fat diet, sedentary lifestyle, or diabetes.
