急性ST段抬高心肌梗死PCI术后运动耐量及影响因素

Exercise tolerance and influencing factors with acute St-segment elevation myocardial infarction patients undergo PCI

运用心肺运动试验(CPET)探究经皮冠状动脉介入治疗(PCI)后急性ST段抬高型心肌梗死(STEAMI)患者运动耐量及影响因素。首先,根据心肺运动试验运动中最大代谢当量进行分组,然后采用单因素分析及多因素Logistic回归分析得出运动耐量减低的影响因素。结果显示,STEAMI患者PCI术后即使血运重建,运动耐量降低者仍偏多,年龄大、体质量指数高、吸烟、PSQI总分高(睡眠质量差)是运动耐量的独立危险因素,对这些危险因素应及时干预,对降低PCI术后心血管事件再发风险有重要的临床价值和意义。

To investigate exercise tolerance and influencing factors in patients with acute ST-segment elevation myocardial infarction(STEAMI)patients undergo percutaneous coronary intervention(PCI)use cardiopulmonary exercise test.First,select patientsandaccording to the maximum metabolic equivalent in cardiopulmonary exercise test,separatethem into two groups.Then,univariate analysis and multivariate Logistic regression analysis were used to screen the influencing factors of impaired exercise tolerance.Conclusion:Even undergoing PCI,exercise tolerance should be emphasized.Older age,smoking,elevated body mass index,,and high total PSQI score(poor sleep quality)were independent risk factors for exercise tolerance.Timely intervention of risk factors affecting exercise tolerance undergoing PCI has important clinical value.
