title: [Exrercise tolerance in patients with coronary artery disease after coronary artery stenting].
abstract: The aim of the research is to investigate the impact of coronary stenting on exercise tolerance after 4-8 week and after 12-15 months. The study involved total 90 patients with coronary artery disease, who underwent coronary stenting. All patients underwent clinical examination, including an assessment of their condition, the frequency of angina attacks, echocardioscopy, resting ECG was recorded in all the patients in the standard 12 -lead veloergometry. Statistical processing was performed using Statistica 6.0 for Windows, the method of Wald - Wolfowitz . Data are presented as arithmetic means and error average M ± m. We used a statistical method of calculation - the median ranks (with the median calculated by the usual rules of statistics - the arithmetic mean of the central members of the ordered series). Significant differences were assessed by t-test . The level of significance was considered significant when p <0,05. According to the monitoring data of patients have a significant increase in exercise tolerance: threshold power increased by 63% and in 12-15 months by 58 % compared with the original. The duration of the test conducted after stenting increased by almost 2 -fold. In addition, significantly reduced the proportion of patients whose test results were evaluated as positive. Stenting of the coronary arteries after 4-8 weeks promotes the significant increase in exercise tolerance that persists after 12-15 months. The factors of associated with insufficient increase in exercise tolerance after stenting according veloergometry are: female gender, diabetes, smoking cessation further contributes to the increase in the threshold of physical activity.
