Cardiovascular risk and subclinical atherosclerosis signs in a military contingent based in the Arctic

Abstract

We evaluated the prevalence of cardiovascular risk and signs of initial atherosclerosis in young and middle aged men, undergoing military service in the Arctic region. It have been found, that military service in the North and the Arctic zone is fraught with negative influence of climatic factors conducive to the development and progression of cardiac disease. The prevalence of classical cardiovascular risk factors had a multidirectional character. The frequency and severity of arterial hypertension was higher in men performing military service in temperate climates. Military contingent of the Arctic region was characterized by overweight, inadequate consumption of fresh fruits and vegetables combined with physical inactivity. The Systemic Coronary Risk Evaluation algorithm and Framingham risk scale have been used for estimation of the probability of cardiovascular events. There was high frequency deployed stages of fatty liver disease in the troops of the Arctic region. Identified a high occurrence of dyslipidemia and 1-hour postprandial hyperglycemia, as well as reducing the elasticity of arteries. Has been noted the hidden character of the violations of lipid and carbohydrate metabolism, which makes them difficult to diagnose through routine survey techniques. For early detection of initial atherosclerotic changes have been recommended the inclusion in the diagnostic algorithm such test as detailed lipid profile, glucose tolerance test, ultrasound examination of the carotid arteries and dynamic sphygmomanometry.
