Interventional Effects on Myocardial Revascularization Post-surgical Patients

Study Overview
=================
Brief Summary
-----------------
The aim is to evaluate the effectiveness of physical exercise on a cycle ergometer combine with CPAP in the postoperative period after myocardial revascularization

Detailed Description
-----------------
Physical exercise on a cycle ergometer combine with CPAP as an adjunct to the rehabilitation of hospitalized subjects who will undergo myocardial revascularization will be safe, decrease the length of stay in the ICU, and help maintain functional capacity

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Conventional Therapy<br>The control program will consist of progressive exercises according to each postoperative day. Two daily sessions with an average duration of 25 min will be performed. In addition to the physiotherapeutic program standardized by the hospital's team of physical therapists, the intervention group will perform physical exercise on a cycle ergometer with CPAP. | Other: Conventional Therapy<br>* Subjects will randomly placed into intervention group and control group . In addition to the physiotherapeutic program standardized by the hospital's team of physical therapists, the intervention group will perform physical exercise on a cycle ergometer with CPAP.<br>|
| Experimental: Cycle ergometer combine with CPAP<br>Physical exercise on a cycle ergometer combine with CPAP will be performed in a single daily session from the second to the fourth postoperative days | Other: Cycle ergometer combine with CPAP<br>* Physical exercise on a cycle ergometer combine with CPAP will be performed in a single daily session from the second to the fourth postoperative days . The maximum exercise time for postoperative day 2 will be 20 min, and 30 min for the third and fourth postoperative days.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Modified Borg scale | The Modified Borg Dyspnoea Scale is most commonly used to assess symptoms of breathlessness. Despite being a subjective measure of exercise intensity, RPE scales provide valuable information when used correctly. | 4th day | 
| 6 min walk distance | The six minute walking test (6MWT) was developed by the American Thoracic Society and it was officially introduced in 2002, coming along with a comprehensive guideline. The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity | 4th day | 
| 1 min sit to stand test | Vaidya et al reported that 1-minute STS test is a simple and sensitive test and appears to be a practical, reliable, valid, and responsive alternative for measuring exercise capacity, particularly where space and time are limited | 4th day | 
| Digital Monovacumeter | The manovacuometer is a simple, quick and non-invasive test which measures the maximal respiratory pressures (MRS).Digital manovacuometer is a reliable and valid instrument for assessing maximum inspiratory pressure and maximum expiratory pressure in healthy subjects | 4th day |
