Clinical Trial Summary

This is a randomized Clinical Trial to assess the effects of Tai Chi Chuan on blood pressure, respiratory muscle strength and functional capacity in patients after recent acute myocardial infarction.

Description:

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).

Intervention

Other:
• Tai Chi Chuan exercise
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
patients in this group held weekly classes of two stretching for 12 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	functional capacity	cardiopulmonary exercise testing (VO2)	Change from Baseline in functional capacity at 90 days
Secondary	respiratory muscle strength	PImax e PEmax were obtained using a pressure tansducer	Change from Baseline in respiratory muscle strength at 90 days
