摘要: 目的: 应用症状限制极限负荷心肺运动试验(CPET)评估稳定性冠心病患者经皮冠状动脉腔内血管成形术(PCI)治疗前后的整体心肺功能变化。方法: 入选2014年8月至12月在本院经冠脉造影和心脏超声等检查诊断为稳定性冠心病患者59例,择期行PCI治疗31例(PCI组),另单纯药物保守治疗28例为对照组。患者治疗前、后均进行CPET。结果: 所有患者均安全完成CPET,无任何并发症。药物对照组治疗前后所有功能指标均无明显变化(P>0.05)。PCI组治疗后仅无氧阈、峰值摄氧量和峰值氧脉搏比治疗前明显提高(P<0.05),其他指标变化不显著(P>0.05)。CPET评估个体化分析发现PCI组治疗后升高(≥10%)峰值摄氧量和峰值氧脉搏比例明显高于对照组(P<0.05)。结论: PCI通过冠状动脉血运重建可明显改善患者心肺功能,提高运动能力。CPET是客观定量评估冠心病治疗效果的一种客观、定量、安全、有效方法。

Abstract: Objective: In order to assess the integrative cardiopulmonary function after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD), we used symptom limited maximum cardiopulmonary exercise testing (CPET). Methods: All 59 patients diagnosed stable CAD by coronary angiography and echocardiography from August to December of 2014 in our hospital, were divided two groups. PCI group, 31 patients received PCI and drugs. Control group, 28 patients received drugs therapy only. All patients performed CPET before and after the treatment. Results: All patients safely completed CPET without any complications. The control group, all functional parameters were unchanged(P>0.05). PCI group, the anaerobic threshold, peak oxygen uptake and peak oxygen pulse increased significantly (P<0.05) from baseline,but not for others (P>0.05). For individual analysis, PCI group had higher rates of increase (≥10% of baseline) in both peak oxygen uptake and peak oxygen pulse than those of control group (P<0.05). Conclusion: CPET is an objective, quantitative, safe and effective method to evaluate the clinical therapeutic efficiency. PCI can improve the integrative cardiopulmonary function in CAD patients.

Key words: stable coronary heart disease, cardiopulmonary exercise testing, percutaneous coronary intervention, drug therapy treatment, objective and quantitative evaluation
