This study aimed to assess whether cardiopulmonary exercise tests contribute to the early diagnosis of myocardial ischemia and evaluate the effect of the percutaneous coronary intervention on the results of cardiopulmonary exercise tests.
Safety,Efficacy
Confirmatory
The primary endpoint was defined as the changes of VO2/WR among the ischemia and control (non-ischemia) groups. The cardiopulmonary tests were scheduled before and within 3 months after (within 3 months) of the percutaneous coronary intervention.
The secondary endpoint was defined as the changes of VO2, VCO2, AT, Peak VO2, T1/2, VO2/HR, R, VE/VO2, VE/VCO2, and VE vs. VCO2 slope among the ischemia and control (non-ischemia) groups. The cardiopulmonary tests were scheduled before and after (within 3 months) of the percutaneous coronary intervention.

Maneuver |
Cardiopulmonary exercise tests are scheduled as non-invasive evaluations for patients whose effort angina is suspected. The method of exercise load is a warm-up of 4 minutes at rest and 4 minutes of 10W, followed by a linear ramp load with a bicycle ergometer that gradually increases at 20W per minute. Ischemia is judged based on ST-segment changes on the stress electrocardiogram performed at the same time. For ischemic-positive patients, the degree of anatomical stenosis is evaluated by coronary CT, stress myocardial perfusion imaging, and coronary angiography to confirm the presence or absence of significant stenosis. Moderate stenotic lesions were evaluated functional ischemia with fractional flow reserve (FFR), resting index, FFR angiography). For patients who are indicated for revascularization and who could undergo complete revascularization by percutaneous coronary intervention, second cardiopulmonary exercise tests are performed within 1 month (ischemic group).
The control group consists of patients whose ischemia was negative in the first cardiopulmonary exercise test. The second tests are performed in 1 to 3 months.

Male and Female
Patients suspected of exertional angina by medical interview, 12-leads electrocardiogram, chest X-ray, transthoracic echocardiography.
Cases with residual lesions, coronary artery bypass surgery, and heart failure symptom of NYHA functional classification II or higher are excluded. In addition, cases with moderate or higher valvular disease, cardiomyopathy, chronic atrial fibrillation or flatter, permanent pacemaker or implantable defibrillator, and lung disease are excluded.
