Abstract :Coronary artery disease is the main cause of death worldwide. Coronary artery bypass graft insert ignore into journalissuearticles values(CABG); is a preferred treatment option for multi-vessel disease and left main disease patients. Physical training insert ignore into journalissuearticles values(recovery); enhances exercise tolerance, an activity of daily living, and quality of life in this patient. For this, the aim of the current study was to investigate the effect of acute high-intensity interval exercise on post-exercise blood pressure in CABG patients. In this study, all patients underwent open-heart surgery at least 1 month before involvement in the study. All Subjects were included after Medical rigorous screening. Participants carried out two experimental sessions of high-intensity interval exercise insert ignore into journalissuearticles values(HIIE); and mild continuous exercise insert ignore into journalissuearticles values(MCE); with a minimum of 72 h intervals: This study employed a randomized, cross-over design, Brachial systolic blood pressure insert ignore into journalissuearticles values(SBP); and diastolic blood pressure insert ignore into journalissuearticles values(DBP); and heart rate insert ignore into journalissuearticles values(HR); were measured Immediately before insert ignore into journalissuearticles values(pre); and after insert ignore into journalissuearticles values(post); and approximately15 mininsert ignore into journalissuearticles values(post-15); and 30 min insert ignore into journalissuearticles values(post-30); after each exercise bout. The Split-Plot Analysis of Variance with repeated measures insert ignore into journalissuearticles values(group × time); was used to analyze the data. Significant post-exercise increases in SBP, and HR were seen following each protocol insert ignore into journalissuearticles values(p<0.05);. Following two bouts, SBP decreased at 15- and 30-min post-exercise in two groups but this decline was more in the HIIE group than MCE. Based on the findings of this study, both high-intensity intermittent and continuous exercise can improve heart function in CABG patients by diminishing BP.
