- Symptom-limited Exercise Duration as an Indicator of Exercise Capacity [ Time Frame: Application was 45 minutes prior to exercise ]Subjects walked on the treadmill as long as they could tolerate, symptom-limited.
- Time-to-onset of 1mm ST Segment Depression [ Time Frame: Application was 45 minutes prior to exercise ]Continuous ECG was recorded during exercise. ECG was reviewed by a board-certified cardiologist.
- Time-to-onset of Angina or Angina Equivalent Symptoms [ Time Frame: Application was 45 minutes prior to exercise ]Onset of angina or angina-equivalent symptoms was assessed from beginning of exercise.
- Maximal ST Depression [ Time Frame: Application was 45 minutes prior to exercise ]Exercise ECG data was reviewed by a board certified cardiologist to assess maximal ST depression.
- Maximal Estimated Workload (in METS) [ Time Frame: Application was 45 minutes prior to exercise ]Maximal estimated workload (in METS) was measured during exercise tolerance test (ETT).
- Magnitude of Reversible Perfusion Defect in SPECT With Wall Motion Assessment (Phase 2) [ Time Frame: Phase 2 was not done. ]Phase 2 of the study involving nuclear imaging was not done because the study was stopped early for lack of enrollment.
- Severity of Angina Was Measured. [ Time Frame: Application was 45 minutes prior to exercise ]Severity of angina was measured using numerical score 1 to 10, where 10 is the worst intensity and 1 is the least.
