Prognostic Values of Some Cardiovascular Risk Factors in Cosmonauts
- 14 Downloads
A ten-year follow-up study was focused on comparison of risk factors of atherosclerosis and damage to target organs in a group of 40- to 65-year-old cosmonauts and volunteers in the same age range. It was shown that the incidence of supraventricular extrasystoles in the groups increased with aging by 85 and 80%, respectively, inferring the risk of supraventricular tachyarrhythmias. The primary predictors of atherosclerosis and coronary artery disease (CAD) in cosmonauts are decreased endothelium-dependent vasodilation in the right brachial artery, C-reactive protein (hsCRP) level > 2 mg/L, and high atherogenic index. These CAD predictors should be of particular concern during medical screening of candidates for cosmonauts.
