title: [Assessment of overall function after percutaneous coronary intervention by cardiopulmonary exercise testing in patients with stable coronary heart disease].
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).
  
  
  CONCLUSIONS
  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.
