N/A effects of exercise training on endothelium-dependent dilation in patients with CABG history. of all 40 patients intending in study, 20 cases will attend supervised aerobic moderate treadmill walking sessions(60-80% of the maximal heart rate predicted for the patient's age), three times a week. The sessions will continue for 6 weeks for each case. Before treadmill walking, 5 minutes of warm up including stretching exercises will perform for each subject. The treadmill walking starts using the Harbor treadmill protocol as follow: 3 minutes of relatively slow "warm-up" speed, followed by gradual increase in constant amount (1 to 4 percent per minute) for up to 10 minutes depending on the person’s fitness. The test will stop prior to achievement of the target heart rate if the patient develops significant chest discomfort, shortness of breath, dizziness, unsteady gait, or if the electrocardiogram shows alarming ischemic changes or serious arrhythmia's.All Patients (cases and controls) will asked to maintain their normal diet and other lifestyle behaviors, as well as their medications. Assessments will then repeat for all 40 subjects, and crossover will occur with final assessments made 6 weeks after entry..
