Abdominal obesity (AO) is associated with a high prevalence of cardiovascular risk factors and contributes to increased cardiovascular morbidity and mortality worldwide. The aim of this study was to assess the informative value of the 6-minute walk test in determining cardiovascular risk in persons over 55 years of age with abdominal obesity. Subjects and methods: The study enrolled 70 patients, including 17 men (24 %) and 53 women (76 %) over 55 years of age. All subjects under study had collection of complaints and anamnesis, anthropometry, 6-minute walking test, biochemical blood tests for glucose, creatinine, lipoproteins and total cholesterol were performed, triplex scanning of brachiocephalic arteries, echocardiography, noninvasive angioscans on the diagnostic complex «AngioScan-01» were performed. Results: All subjects were divided into 2 subgroups: with AO – 52 patients, and without it – 18 patients. Patients with AO had a greater number of conditions associated with increased risk of death from cardiovascular complications. Smoking, hyperglycemia, hypertriglyceridemia, general obesity, diabetes mellitus, arterial hypertension, coronary heart disease, and chronic kidney disease stage 3 were statistically significantly more common in them. The study showed that distance in the 6-minute walk test is decreased in patients with AO, and the decrease in this distance correlates with lower indices of endothelium-dependent vasodilation. Conclusions: the 6-minute walk test is a simple functional test that can be used as an additional criterion of cardiovascular risk assessment in outpatient settings. Its determination is especially important in abdominal obese patients who are at high cardiovascular risk.
