  1. Non-EX Non-Exercisers, CMD Coronary Microvascular Dysfunction, DTS Duke Treadmill Score, LBBB left bundle branch block, HR heart rate, SBP systolic blood pressure, DBP diastolic blood pressure. Time between tests represents the time between the exercise stress test and peripheral arterial tonometry in exercisers. No significant effect of exercise or CMD for all variables (All P > 0.05).
