Abstract：Objective To observe the effect of cardiopulmonary rehabilitation exercise on exercise tolerance and quality of life in old patients with chronic obstructive pulmonary disease and chronic heart failure(COPD-CHF).Methods A total of 100 old inpatients with COPD-CHF were recruited from the First Affiliated Hospital of Qiqihar Med-ical University between March,2023 and January,2024.They were randomly divided into control group(n=50)and rehabilitation group(n=50).After discharge,both groups received routine medication treatment,while the rehabilitation group additionally underwent cardiopulmonary rehabilitation exercise,for three months.Before and after intervention,left ventricular ejection fraction(LVEF)was measured with cardiac color Doppler ultra-sound,and pulmonary function was evaluated with cardiopulmonary exercise testing;while they were assessed with the 6-minute walk distance(6MWD),COPD Assessment Test(CAT)and Minnesota Living with Heart Fail-ure Questionnaire(MLHFQ).Results Four patients dropped out from each group.Anaerobic threshold,maximum oxygen uptake,maximum voluntary ventilation,LVEF and 6MWD increased in the rehabilitation group after intervention,(t>8.328,P<0.001),and they were better than those in the control group(t>6.717,P<0.001);while the scores of CAT and MLHFQ de-creased in the rehabilitation group(t>12.070,P<0.001),and they were better than those in the control group(t>8.297,P<0.001).Conclusion Cardiopulmonary rehabilitation exercise can improve cardiopulmonary function,exercise tolerance and quality of life in old patients with COPD-CHF.
