Abstract
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.
