Cycle Ergometer Exercise in Phase I of Cardiac Rehabilitation After Cardiac Surgery

January 28, 2021 updated by: Ada Clarice Gastaldi, University of Sao Paulo
The prevalence of heart diseases has increased significantly in recent years and it is a health public problem due to an increased risk of death by several reasons. A cardiac surgery is an alternative of treatment for critical injuries heart valves and coronaries arteries. Changes in respiratory system resulting from cardiac surgery are well established and include a reduced functional capacity due post-surgical pain, causing increased respiratory function and increased oxygen consumption . The exercises with the cycle ergometer in phase I of cardiac rehabilitation can improve peripheral muscle strength, functional capacity and perception of dyspnea when used postoperatively and there are speculations if an earlier carried out can contribute to a better postoperative evolution of patients, but these benefits in phase I of the Rehabilitation Cardiac are not well defined in the literature. Objective: To evaluate the exercises effects with ergometer cycle in the postoperative course of patients undergoing cardiac surgery. Method: Patients will be recruited the cardiac surgery service of Polyclinic Pato Branco in the city of Pato Branco in state of Paraná, of both sexes, appropriate for the inclusion criteria, which will be evaluated by pulmonary function tests (strength of respiratory muscles, submaximal exercise test, dyspnea scales, laboratories tests and radiological exam). All patients will be randomly assigned for one of two groups: the control group (Conventional treatment) and rehabilitation group (conventional treatment +cycle ergometer), for about 7 days at postoperative period. Patients will be reevaluated on the third postoperative day and at discharge. Clinical evolution data will be collected from the records and notes of the medical staff and monitoring physiotherapist.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of six-minute walk test (6MMWT) distance
Time Frame: Before surgery ,third and seventh postoperative day
The six-minute walk test will be conducted with monitoring blood pressure, HR, RR and SpO2 in a hall plan, with distances previously marked. The patient will be accompanied by the researcher and encouraged by constant verbal stimulation, walking as fast as possible, if the patient stop walking the timer will keep triggered. Will use the oximeter with the sensor on the third finger of the right hand, and a certain reading after the signal stabilization and at the same time we get the heart rate. Will be used to calculate the expected value, and reference to distance in the 6MWT, the equations proposed by Enright and Sherrill (1998) determining the percentage of predicted for each test performed by patient.
Before surgery ,third and seventh postoperative day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change of spirometric values
Time Frame: Before surgery ,third and seventh postoperative day
Spirometry will be performed according to criteria of the American Thoracic Society and the Brazilian Consensus Spirometry. Values will be observed from CVF, VEF1 e PEF.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
