About this study

Background:Patients with a recent myocardial infarction (MI) present a reduction in functional capacity expressed as a decrease in peak oxygen consumption (VO2 peak). The impact of a Tai Chi Chuan (TCC) cardiac rehabilitation program for patients recovering from recent MI has yet to be assessed. Our goal is to evaluate functional capacity after a TCC-based cardiac rehabilitation program in patients with recent MI.

Methods: A single-blind randomized clinical trial was conducted. The researchers who performed the tests were blinded to group allocation. Between the 14th and 21st days after hospital discharge, all patients performed a cardiopulmonary exercise testing and a laboratory blood workup. Mean age was similar (56 ± 9 years in the TCC group and 60 ± 9 years in the control group). Patients allocated to the intervention group performed 3 weekly sessions of TCC Beijin style for 12 weeks (n = 31). The control group participated in 3 weekly sessions of full-body stretching exercises (n = 30).

Treatment and study plan

Tai Chi Chuan exercise

Other

patients in this group held three weekly classes of 60 minutes during 12 weeks of Tai Chi Chuan, Yang style. The exercises will be mild to moderate (HR 60 to 75% of HR Max). Slow movements combined with exercises and maintained using your own body weight.

stretching exercise

Other

patients in this group held weekly classes of two stretching for 12 weeks.

Primary outcomes

  1. functional capacity

    Time frame: Change from Baseline in functional capacity at 90 days

    cardiopulmonary exercise testing (VO2)

Secondary outcomes

  1. respiratory muscle strength

    Time frame: Change from Baseline in respiratory muscle strength at 90 days

    PImax e PEmax were obtained using a pressure tansducer

  2. Ambulatory blood pressure in 24 hours

    Time frame: Change from Baseline in blood pressure at 90 days

    24-hour blood pressure
