Observation on the effect of respiratory training combined with cardiac rehabilitation exercise training in patients with chronic heart failure
Objective To observe the practical effect of respiratory training combined with cardiac rehabilitation exercise training in patients with chronic heart failure.Methods 66 patients with chronic heart failure were selected and divided into a control group(33 cases)and an observation group(33 cases)according to lottery method.The control group received respiratory training,and the observation group received respiratory training combined with cardiac rehabilitation exercise training.Comparison was made on cardiac function indicators[left ventricular end-systolic volume(LVESV),left ventricular end-diastolic volume(LVEDV),left ventricular ejection fraction(LVEF)],pulmonary function indicators[maximum volume per minute(MVV),forced expiratory volume in one second(FEV1),forced vital capacity(FVC)],exercise tolerance and incidence of adverse cardiovascular events before and after intervention.Results After intervention,LVESV,LVEDV and LVEF in both groups were better than those before intervention;the observation group had LVESV of(63.50±28.14)ml,LVEDV of(139.65±23.38)ml and LVEF of(49.27±3.54)%,which were better than(86.87±30.62)ml,(163.73±27.01)ml and(38.11±2.59)%in the control group(P<0.05).After intervention,MVV,FEV1 and FVC in both groups were higher than those before intervention;the observation group had MVV of(89.81±16.49)L/min,FEV1 of(2.90±0.61)L and FVC of(3.13±0.67)L,which were higher than(77.64±15.53)L/min,(2.38±0.56)L and(2.58±0.61)L in the control group(P<0.05).After intervention,the 6-min walking distance and peak oxygen uptake in both groups were higher than those before intervention;the 6-min walking distance and peak oxygen uptake in the observation group were(357.46±29.08)m and(19.81±0.73)ml/(kg·min),which were higher than(280.34±27.12)m and(15.42±0.65)ml/(kg·min)in the control group(P<0.05).The incidence of adverse cardiovascular events in the observation group was 3.03%,which was lower than 18.18%in the control group(P<0.05).Conclusion Respiratory training combined with cardiac rehabilitation exercise training as an intervention program can effectively improve the cardiopulmonary function of patients with chronic heart failure,increase their exercise tolerance,reduce the incidence of adverse cardiovascular events,and is worthy of promotion.
