- Abstract:
- Introduction: Cardiovascular disease is a major health threat worldwide. Many people recovering from acute myocardial infarction or invasive cardiac treatment benefit from rehabilitation programs. Therefore, it is an important task to improve these rehabilitation programs. Aims of the study: This study investigates the effect of yoga on the cardiovascular system in a rehabilitation program for people recovering from cardiovascular disease. The purpose was to investigate whether yoga can be a useful adjunct to a cardiac rehabilitation program. This study was designed as a pilot study with a small number of participants to also investigate feasibility. Methods: 20 participants aged between 43 and 79 years were recruited. All of them started a four-week rehabilitation program at the St. Radegund Rehabilitation Clinic near Graz, Austria, to recover from an acute myocardial infarction or invasive heart surgery. Ten of them were randomly selected for the yoga group and ten for the control group. Each participant in the control group completed the recommended and standardized rehabilitation program. The participants in the yoga group also participated in supervised yoga sessions for approximately 25 minutes in the morning and evening from Monday to Friday. On the day after arrival and the day before departure, the supine-to-stand test was performed with each participant. Cardiac index (CI), total peripheral resistance index (TPRI), heart rate (HR), systolic and diastolic blood pressure (sBP, dBP), mean arterial pressure (MAP), and stroke index (SI) were calculated and analyzed. Results: 20 participants completed the entire study protocol. Applying a metric statistic revealed no significant effects for the hemodynamic parameters CI, TPRI, HR, MAP, sBP, dBP, and SI by the yoga intervention, however a trend towards an interaction was found for TRPI (p=0.077). When the groups were analyzed separately using the nonparametric Wilcoxon test, the yoga group showed more significance between pre- and post-measurements. Discussion: The present study indicated that yoga may have a positive effect on the cardiovascular system. Although no clear conclusion was to be drawn by parametric tests, analyzing the groups separately revealed a positive effect in the yoga group, but no difference in the control group. However, the present results should be viewed with caution as the statistical power was low. Larger studies are needed to make accurate statements about the effect of yoga on the cardiovascular system.
