The Effect and Safety of Aerobic Interval Training According to Exercise Intensity in Acute Coronary Syndrome

Purpose: To evaluate the effect of increasing the maximal oxygen uptake ( JOURNAL/jcprh/04.02/01273116-202005000-00008/math_8MM1/v/2020-04-30T103411Z/r/image-png O2max) and the safety of maximal-intensity aerobic interval training (MAIT) compared with high-intensity aerobic interval training (HAIT). Methods: Forty-seven patients with first-ever acute coronary syndrome were assigned to MAIT or HAIT. Subjects underwent adaptation period during the first 2 wk of cardiac rehabilitation and then MAIT at 95-100% of the heart rate reserve or HAIT at 85% of the heart rate reserve, 3 d/wk for 4 wk. The primary outcome was JOURNAL/jcprh/04.02/01273116-202005000-00008/math_8MM2/v/2020-04-30T103411Z/r/image-png O2max. The secondary outcomes were major cardiovascular complications, hemodynamic responses, myocardial oxygen demand, cardiometabolic health, and echocardiographic findings. Results: A total of 670.5 hr of MAIT and HAIT were completed. After 6 wk of aerobic interval training, JOURNAL/jcprh/04.02/01273116-202005000-00008/math_8MM3/v/2020-04-30T103411Z/r/image-png O2max was significantly increased in both groups. However, the increment of JOURNAL/jcprh/04.02/01273116-202005000-00008/math_8MM4/v/2020-04-30T103411Z/r/image-png O2max was significantly greater in the MAIT group than in the HAIT group (P
