摘要
目的研究间歇性高强度心脏康复训练对心力衰竭患者心肌应变参数、心功能和运动耐力的影响。方法将101例心力衰竭患者随机分为对照组(n=50)和观察组(n=51)。对照组患者行常规康复运动,观察组患者行间歇性高强度心脏康复训练。两组患者均干预6个月。比较两组患者干预前后的心肌应变参数、心功能、运动耐力。结果干预6个月后,观察组患者左、右心室最大收缩期纵向应变水平均高于对照组(均P<0.05),两组患者的左、右心室最大收缩期纵向应变率水平差异均无统计学意义(均P>0.05);观察组患者的左室射血分数高于对照组(P<0.05),两组患者的左室舒张末期内径差异无统计学意义(P>0.05);观察组患者的峰值摄氧量、峰值功率、运动持续时间、无氧阈值水平均高(长)于对照组(均P<0.05)。结论间歇性高强度心脏康复训练可改善心力衰竭患者心肌应变参数和心功能,提高其运动耐力,值得临床推广应用。
Objective To investigate the effects of intermittent high-intensity cardiac rehabilitation training on myocardial strain parameters,cardiac function and exercise tolerance in patients with heart failure.Methods A total of 101 patients with heart failure were randomly divided into a control group(n=50)or an observation group(n=51).The control group patients performed routine rehabilitation exercises,while the observation group patients performed intermittent high-intensity cardiac rehabilitation training.Both groups were intervened for 6 months.The myocardial strain parameters,cardiac function and exercise tolerance were compared between the two groups before and after the intervention.Results After the 6-month intervention,the left and right ventricular maximal systolic longitudinal strain levels of the observation group were higher than those of the control group(all P<0.05),and there was no significant difference in the left or right ventricular maximal systolic longitudinal strain rate between the two groups(all P>0.05).The left ventricular ejection fraction of the observation group was higher than that of the control group(P<0.05),and there was no significant difference in the left ventricular end-diastolic diameter between the two groups(P>0.05).The peak oxygen uptake,peak power,exercise duration and anaerobic threshold levels of the observation group were higher/longer than those of the control group(all P<0.05).Conclusion The intermittent high-intensity cardiac rehabilitation training can improve myocardial strain parameters,cardiac function and exercise tolerance in patients with heart failure,which is worthy of clinical promotion and application.
