Metabolic syndrome, a group of cardiovascular risk factors related to insulin resistance, is a major determinant of cardiovascular mortality.

Intermittent claudication is a symptom of an early stage of atherosclerosis.

The aim of this study is to determine the prevalence of the metabolic syndrome in patients with intermittent claudication and its correlation with age, gender, localization of arterial obstruction and association with coronary artery disease.

Intermittent claudication patients
Patients with intermittent claudication with metabolic syndrome and patients with intermittent claudication without metabolic syndrome.

Detailed Description:

Studies correlating metabolic syndrome and several illnesses are being published, especially affections associated with atherosclerosis, like coronary artery disease, cerebrovascular disease and peripheral arterial disease.

The term peripheral arterial disease, however, refers to several stages of the development of atherosclerosis in the extremities, comprising since asymptomatic patients as far as individuals with critical ischemia.

Intermittent claudication is a symptom of an early stage of atherosclerosis, when medical interventions may still prevent the progression of the disease. Despite the importance of a precocious diagnosis of metabolic syndrome to initiate adequate treatment, its prevalence among these patients is not well determined in the literature.

This is the biggest casuistic in the literature as far as we know.
