Predictors of cardiovascular disorders in students at the early stage of adjustment to social and ecological environments

The intensity of cardiovascular system is an integral indicator of the body's adjustment to various factors (including living and learning environments). The purpose of the paper is to identify the predictors of cardiovascular system disorders in students at the early stage of adjustment to living and learning environments. Materials and Methods. The authors examined 99 1st-year female students living in contrasting climatic and ecological environments (in Surgut, Khanty-Mansi Autonomous Okrug-Yugra (n=48) and in Simferopol, the Republic of Crimea (n=51)). It was a parallel-group study. Angiography was used to estimate the blood flow. The analysis of the heart rhythm regulation is based on the cardiointervalography. Results. It was found out that augmentation index normalized to the pulse rate of 75 BPMs, the index of refraction and pulse rate were significantly higher in the group of female students living in the Republic of Crimea. This fact indicated increased arterial wall stiffness. Conclusion. The study made it possible to determine the predictors of cardiovascular system disorders in female students. Arterial wall stiffness, high tonus of small arteries and adaptive potential corresponding to the tension of adjustment mechanisms were among predictors observed in female students from the Republic of Crimea. In turn, small artery stiffness was the main predictor of CV disorders in female students living in Khanty-Mansi Autonomous Okrug-Yugra.
