Abstract

BACKGROUND

Coronary artery bypass grafting a frequent surgical procedure to treat coronary heart disease, uses the patient's own veins or arteries to bypass narrowed areas and restore blood flow to heart muscle. Cardiac rehabilitation follows this procedure and includes psychological and nutritional support along with the regular practice of physical exercises.

OBJECTIVE

The aim of this study was to investigate the acute effects of the aerobic exercise on the blood pressure of patients after coronary artery bypass grafting.

METHODS

After 30 days of surgical procedure, 14 patients were assigned to the aerobic exercise group (exercise on the cycle ergometer for 35 minutes), while 8 patients were assigned to the control group (absolute rest for 35 minutes). Blood pressure was measured by a digital automatic device before and after 24 hours of the experiment in both groups.

RESULTS

Systolic (P = 0.639) and diastolic (P = 0.103) blood pressures were similar between CG and AEG at baseline. Regarding intragroup differences, no significant changes were observed after 24 hours for SBP in the CG (P = 0.999) and AEG (P = 0.244). On the other hand, significant changes were found for DBP after 24 hours for the CG (P = 0.007) and AEG (P = 0.015). When CG and AEG were compared after 24 hours, no significant differences were found for SBP (P = 0.999) and DBP (P = 0.054).

CONCLUSIONS

We found decreased diastolic blood pressure in the aerobic exercise group when the results for pre-training and post-training were compared. However, to support our findings further research is needed, preferably using randomized controlled trials.

摘要

背景

冠状动脉旁路移植术是治疗冠心病的常见外科手术，利用患者自身的静脉或动脉绕过狭窄区域，恢复心肌的血流。心脏康复在该手术后进行，包括心理和营养支持以及定期进行体育锻炼。

目的

本研究的目的是调查有氧运动对冠状动脉旁路移植术后患者血压的急性影响。

方法

手术30天后，14名患者被分配到有氧运动组（在自行车测力计上运动35分钟），而8名患者被分配到对照组（绝对休息35分钟）。两组在实验前和实验24小时后均使用数字自动设备测量血压。

结果

在基线时，对照组（CG）和有氧运动组（AEG）的收缩压（P = 0.639）和舒张压（P = 0.103）相似。关于组内差异，对照组（P = 0.999）和有氧运动组（P = 0.244）在24小时后收缩压未观察到显著变化。另一方面，对照组（P = 0.007）和有氧运动组（P = 0.015）在24小时后舒张压有显著变化。当在24小时后比较对照组和有氧运动组时，收缩压（P = 0.999）和舒张压（P = 0.054）未发现显著差异。
