  • Abstract
  • Look Inside

The aim of this study was to clarify whether the anaerobic threshold (AT) in patients with ischemic heart disease is determined by exercise-induced myocar-dial ischemia.

A) The reproducibility of the VO2 at the AT (AT VO2) were studied. In 13 patients with exercise-indu-ced myocardial ischemia, submaximal Treadmill exer-cise tests were performed twice using a cardiopulmo-nary monitoring system. The reproducibility of the AT VO2 was good (r=0.92), and the mean ± SD was -1.3±8.2%.

B) The change of the AT VO2 after percutaneous transluminal coronary angioplasty (PTCA) was stud-ied.
