Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention will commence after inpatient discharge. In the outpatient cardiac rehabilitation center
Patient with coronary bypass who will received 12 consecutive weeks of physical training, with a frequency of 3 days per week, 60 minutes per session, consisting on: 5 minutes of warm-up, 40 minutes of work in treadmill and cycloergometer, and a 5-minute cool down. An intensity between 50% and 70% of the reserve heart rate or 3-6 in the modified Borg scale.
In addition, two sessions per week of resistance training in upper extremities with moderate intensity (3-5 modified Borg) in this days the patient will receive 10 minutes of resistant training whit elastic bands of different resistances 4 sets of 8 - 10 reps 3 or 4 exercises like shoulder abduction, elbow flexion and extension and so on, this days the session will take 10 more minutes. The intervention will be delivered by a specialized physiotherapist in cardiopulmonary, and it will be provided individually.
Each day the patient will sign an attendance registry which contents the follow up.

Efficacy
Statistical methods / analysis
The Stata 12.0 software will be used. The difference between measurements will be compared between groups using the Student t-test for independent data; while the intra-group comparison of the change before and after the intervention will be made using the Student t-test for paired data. A level of 5% will be considered for the entire analysis.
Prior A Linear Mixed Model analysis (LMM) will be use to estimate the mean peak VO2
from the mean 6 MWD (minute walk distance)

Summary
Brief summary
Introduction: physical exercise within cardiac rehabilitation processes has shown a 20-25% reduction in total and cardiovascular mortality when compared to rehabilitation that does not include this type of treatment. On the other hand, the differences in their effectiveness for subjects with percutaneous revascularization and coronary bypass is not clear.
Objective: To compare the effects of cardiac rehabilitation on autonomic, hemodynamic, metabolic and physical capacity parameters among subjects undergoing percutaneous revascularization and coronary bypass for acute coronary syndrome (ACS).
Methods: Quasi-experimental study conducted in 58 subjects undergoing percutaneous coronary revascularization (n=29) and cardiac bypass (n=29). All will be evaluated at the beginning of the protocol and after 12 weeks of aerobic training within a cardiac rehabilitation program (phase II), with a frequency between 3 to 5 sessions per week and a duration of 60 minutes per session at an intensity of 50% to 70%. Heart Rate Reserve (HRF) or perception of exertion (Modified Borg3/6). The variables evaluated will be: cardiorespiratory capacity, heart rate variability, lipid profile (total cholesterol, triglycerides) and glycemia. Expected results: This work presents the opportunity to identify differences in the scope of physical exercise protocols included in phase II cardiac rehabilitation programs, on functional physical capacity, hemodynamic, metabolic and cardiovascular autonomic variables in subjects undergoing percutaneous revascularization and coronary bypass for ACS. This would support the need to continue or adjust the programs used in the institutions that provide these rehabilitation services.
The hypotesis is that Person with percutaneous revascularization will have bigger Heart Rate Variability, because by the heart manipulation in coronary bypass, is altered autonomic modulation
