PCI术后患者平板运动试验与心肺运动试验比较研究

目的 探讨平板运动试验与心肺运动试验的相互关系及临床应用价值。方法 选取解放军总医院心血管内科38例行经皮冠状动脉介入治疗（PCI）的冠心病患者,随机交替进行心肺运动试验及平板运动试验检查,比较各项试验参数情况。结果 患者行心肺运动试验检查时静息血压及运动中最大血压均高于平板运动试验（P＜0.01）,平板运动试验中患者的运动耐量（MET）大于心肺运动试验（P＜0.01）,且两者存在相关关系。患者在平板运动试中自我感知运动强度评分量表（Borg评分）低于心肺运动试验,差异有统计学意义（P＜0.01）。心肺运动试验各参数中,男性与女性相比,运动时间、运动耐量、最大耗氧量表现出统计学差异（P＜0.05）。结论 平板运动试验与心肺运动试验同为负荷试验,两者不可互相替代,因根据患者不同情况进行不同的选择。对于PCI术后的患者而言,心肺运动试验可以提供更多运动能力评价的客观指标。

A comparative study of treadmill exercise test and cardiopulmonary exercise test in patients after percutaneous coronary intervention

Objective To explore the relationship and the clinical application between treadmill exercise test and cardiopulmonary exercise test. Methods 38 patients patients with coronary heart disease undergoing percutaneous coronary intervention (PCI) were selected from the cardiovascular department of PLA General Hospital. The cardiopulmonary exercise test and treadmill exercise test were performed randomly and alternately. The test parameters were compared. Results Resting blood pressure and maximum blood pressure in cardiopulmonary exercise test were higher than those in treadmill exercise test (P < 0.01). The exercise tolerance (MET) in treadmill exercise test was higher than that in cardiopulmonary exercise test (P < 0.01), and there was a correlation between them. The Borg score of patients in treadmill exercise test was lower than that in cardiopulmonary exercise test (P < 0.01). In the parameters of cardiopulmonary exercise test, there were significant differences in exercise time, exercise tolerance and maximal oxygen consumption between men and women (P < 0.05). Conclusion Both treadmill exercise test and cardiopulmonary exercise test are stress testing, they cannot be replaced by each other, we should chose the appropriate test according to different conditions of patients. Cardiopulmonary exercise test can provide more objective indexes to evaluate exercise ability for patients undergoing PCI.
