- Brief Summary
Cardiac rehabilitation, which is a set of interdisciplinary interventions aimed at patient care, has been fundamental in trying to reduce the incidence of deaths and comorbidities in heart disease patients. Physical exercise, in turn, is the main component of cardiac rehabilitation, however, the effects and dose-responses still require further clarification. The objective of the present study was to compare the effect of High Intensity Interval Training in relation to Aerobic Training on the cardiac power index in patients with coronary artery disease undergoing primary angioplasty. Methods: In this Randomized Clinical Trial, 25 individuals of both sexes, aged between 40 and 65 years, were randomly distributed into a High Intensity Interval Training Group (HIIT Group) and a Moderate Continuous Training Group (MCT Group), with the training carried out three times weekly, with a total duration of 12 weeks. Results: the High Intensity Interval Training (HIIT) Group, when compared to Aerobic Training (MCT), produced an increase in Cardiac Power Production (0.94±0.05 vs. 0.95±0.04) while the MCT group showed a decrease (0.86±0.03 vs. 0.81±002) with a significant difference between groups (p<0.05). Regarding ventricular function, verified through the left ventricular ejection fraction, High Intensity Interval Training demonstrated an increase in the left ventricular ejection fraction (65.6±1.2% vs. 74.9±1.35%, p<0.05 while MCT also showed an increase (62.8±1.7 vs. 64.9±2.0, p<0.05), however with an intergroup difference with p<0.05. Conclusion: High Intensity Interval Training compared to Continuous Moderate Training, it seems have additional benefits in the Cardiac Power Index and left ventricular ejection fraction in post-infarction patients undergoing Primary Angioplasty

- Primary Outcome Measures
Name Time Method Expected outcome 1: an effect size of at least 9% was expected between High Intensity Interval Training when compared with Moderate Aerobic Training, on the Cardiac Power Index in patients undergoing Primary Angioplasty, through 12 weeks of training;Outcome found 1: High Intensity Interval Training increased the Cardiac Power Index by 14% when compared to Moderate Training, over a 12-week period of intervention
- Secondary Outcome Measures
Name Time Method Expected outcome 2: a greater effect of High Intensity Interval Training, when compared to Continuous Aerobic Training, was expected on the left ventricular ejection fraction in patients undergoing Primary Angioplasty;Outcome found 2: High Intensity Interval Training demonstrated an effect of at least 12% greater on left ventricular ejection fraction, when compared to Continuous Moderate Training
