Abstract

Background

Regular exercise training has been shown to reduce mortality, improve functional capacity; and control the risk factors in myocardial infarction (MI) patients. Heart rate recovery (HRR) is a strong independent mortality predictor in patients with previous MI.

Aim

The main objective of this study was to investigate the impact of exercise training on heart rate recovery in patients post anterior myocardial infarction.

Methods

We recruited patients one month after having anterior MI who were referred to cardiac rehabilitation (CR) clinic in Ain Shams University hospital between October 2016 and July 2017. All the patients participated in exercise training sessions 3 times a week for 12 weeks. Symptom limited treadmill exercise test was done before and after exercise training program to calculate heart rate recovery in 1st minute (HRR1) and 2nd minute (HRR2).

Results

A total of 50 patients, including 44 (88%) males, completed the exercise training program. The mean age was 51 years. Statistically significant improvement in HRR1 and HRR2 was observed (p value <0.001) after completion of exercise based cardiac rehabilitation program. Significant improvement in resting heart rate was also observed (p value <0.001). Moreover, metabolic equivalent (METs) and HR reserve were improved significantly (p value <0.001). No statistically significant changes were observed in resting systolic and diastolic blood pressures and maximum HR (p value = 0.95, 0.76 and 0.31 respectively).

Conclusion

Exercise training improves HRR, resting HR, METs and HR reserve in post anterior MI patients.

运动训练对前路心肌梗死患者心率恢复的影响

有规律的运动训练已被证明可以降低死亡率，提高身体机能;控制心肌梗死(MI)患者的危险因素。心率恢复(HRR)是既往心肌梗死患者强有力的独立死亡率预测指标。目的本研究的主要目的是探讨运动训练对前路心肌梗死患者心率恢复的影响。方法招募2016年10月至2017年7月在艾因沙姆斯大学医院心脏康复(CR)诊所转诊的前路心肌梗死1个月患者。所有患者均参加运动训练，每周3次，共12次 周。在运动训练计划前后分别进行症状限制跑步机运动试验，计算第1分钟(HRR1)和第2分钟(HRR2)的心率恢复。结果50例患者均完成运动训练，其中男性44例(88%)。平均年龄为51岁 岁。完成以运动为基础的心脏康复计划后，HRR1和HRR2有统计学意义的改善(p值 <0.001)。静息心率也有显著改善(p值 <0.001)。此外，代谢当量(METs)和HR储备显著提高(p值<0.001)。静息时收缩压、舒张压及最大HR变化无统计学意义(p值 = 分别为0.95、0.76、0.31)。结论运动训练可提高心肌梗死前路后患者的HRR、静息HR、METs和HR储备。
