Respiratory muscle training in patients with acute MI and COPD reduced hospitalizations for heart failure (7.8% vs 14.6%) and pneumonia (2.1% vs 15.3%) over 12 months.
Does respiratory muscles training improve physical capacity and clinical outcomes in patients with acute myocardial infarction and concomitant COPD?
Early initiation of respiratory muscle training in patients with acute myocardial infarction and COPD significantly improves physical capacity, quality of life, and reduces hospitalizations at 1 year.
Absolute Event Rate: 0% vs 0%
Background: Patients with myocardial infarction (MI) and concomitant Chronic Obstructive Pulmonary Disease (COPD) often can't take part in regular physical trainings. Purpose: To study the effect of respiratory muscles trainings (RMT) in patients with acute MI andCOPD. Methods: 87 MI pts 68,1±4,3 yrs old were randomized to an exercise training group (EG) or to a control group (CG). Pts were on their 5-7 day of MI and had COPD. The EG participated in a RMT with gradual increase of inspire and expire resistance. RMT were started at the hospital on the 5-7th day after MI and were continued for 12 months at home by patients themselves. Results: In 1 year the distance of 6 min walk testincreased in EG (in1 year 285±8,7m in EG vs 275,3±9,28 m in CG,p<0,01). Peak oxygen consumption also increased in EG (in 1 year 6,84±1,55 in EG vs 4,61±1,16 ml/kg/min in CG, p<0,01). There was an increase in the maximal inspiratory mouth pressure in most of pts (5,6±0,8 kPa vs 4,1±1,1kPa; p<0,01 in 12 mths). Health related quality of life (HRQL) increased in both groups, but in EG pts it grew higher. Total score of SGRQ in 12 mths was 47,6±1,1 vs 59,5±1,2, p< 0,05, according to SF-36 results in PF, BP, VT, RE scales were higher in EG pts. In a year there were no lethal outcome in both groups. EG pts had less hospitalizations because of HF progression (7,8% in EG vs 14,6% in CG) and pneumonias (2,1% vs 15,3%). Conclusion: RMT in pts with MI and COPD can be started at their acute period. It improves physical capacity, increase HRQL and decrease number of hospitalizations during first year after MI.
