Angioplasty
Conditions
Interventions
Subjects allocated to the HIIT protocol will undergo “sprints” with progressive blocks, times and speeds throughout the training period for better physiological adaptation. The total intervention time

Inclusion criteria
Inclusion criteria: The main inclusion criteria to participate in the present study are participants between 40 and 65 years old; who underwent myocardial revascularization through angioplasty with occlusion = 50%; must have preserved ejection function with an ejection fraction = 40%; no signs of moderate or severe myocardial ischemia detected by perfusion scintigraphy; do not present with angina; do not present ischemia caused by physical exercise; not participate in any type of systematic physical activity; and be classified among those irregularly active
Exclusion criteria
Exclusion criteria: Those patients who present the following symptoms during the study will be excluded from the study. unstable angina; decompensated systemic arterial hypertension with SBP=180 mmHg or DBP=110 mmHg; drop in orthostatic pressure of 20 mm Hg with symptoms, significant aortic stenosis with aortic valve area of 1.0 cm2; uncontrolled ventricular or atrial arrhythmia; sinus tachycardia =120 bpm; third-degree atrioventricular block without a pacemaker; active pericarditis or myocarditis; recent embolism; acute thrombophlebitis; uncontrolled diabetes mellitus; have orthopedic limitations or any physical or mental limitation that prevents the performance of physical exercises; not attending at least 85% of physical training sessions or missing an entire week
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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
| Measure | Time frame |
|---|---|
| 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 | — |
