  Purpose

The purpose of this study was to determine the effects of exercise training on insulin resistance in subjects with coronary artery disease independent of changes in weight, diet, or the effect of an acute bout of exercise. We hypothesized that subjects with CAD and high normal or impaired glucose tolerance performing 12 weeks of aerobic exercise training while on a non weight-reducing diet, would have a greater decrease in insulin resistance than controls measured at 72 hours following their last bout of exercise.

Criteria

Inclusion Criteria:

  • men and women over 18 years of age
  • fasting plasma glucose concentration 5.4-7.7 mmol/L
  • confirmed CAD (diagnosed on the basis of a previous myocardial perfusion study or cardiac catheterization, or a history of a myocardial infarction or coronary artery angioplasty or coronary artery bypass surgery).

Exclusion Criteria:

  • known type 1 or 2 diabetes
  • clinical heart failure
  • uncorrected significant valvular or congenital heart disease
  • significant obstructive pulmonary disease (forced expiratory volume in 1 sec / forced vital capacity < 0.5)
  • uncontrolled hypertension (blood pressure > 220 / 120 mm Hg)
  • participation in a regular exercise program within the preceding three months
  • inability to perform exercise training, atrial fibrillation
  • a permanent pacemaker
  • regularly used corticosteroid
  • recent (< 3 months) myocardial infarction, unstable angina, coronary artery bypass graft surgery, or coronary artery angioplasty
  • run-in phase fasting blood glucose was < 5.4 mmol/L or > 11.1 mmol/L at 2 hours following the 75 gram oral glucose load.
