Abstract
Considering the proved effect of regular exercise on vessels functions, the purpose of this research was to investigate the effect of eight-week endurance training on selected biomechanics parameters of blood and vessel of cardiovascular patients, 4 week after coronary artery angioplasty. In this semi-empirical research, 30 patients with coronary arteries who had percutaneous intervention (PCI) with average age of 55.43+5 years, ejection fraction of 51+5.04, functional capacity of 8.96+2.41 were selected randomly from the patients referring to Qom Rehabilitation Clinic and they were divided into two control and experimental groups. Using Doppler Ultrasound device Logiq.5 Model General Electric the diameter of vessel rested Lumen in systolic and diastolic phase and the diameter of intima-media of bilateral carotid artery were measured both before and after the performing the exercises in both groups. Endurance exercise program was performed three sessions a week during eight weeks using treadmill, arm ergo-meter, and workbench bike. Descriptive statistics was used for describing the data (average and standard deviation), K-S test was used for analyzing the normality of data natural distribution, Loon test was used to determine the variance homogeneity and independent student t-test was used for inferential analysis in order to compare the inter-group averages in 0.05 meaningfulness level. The difference of average rested lumen diameter of bilateral carotid artery was meaningful in increasing side and this difference in the intima-media ratio to the left carotid artery diameter in its decreasing side was meaningful. Considering the results of routine endurance practices, sub-maximum level could be recommended for dynamic correction of blood flow and reconstruction of vascular wall of cardiovascular patients.
