| Objective: To investigate the effects of home-based exercise rehabilitation under the guidance of remote cardiogram monitoring on exercise tolerance and life quality of patients after percutaneous coronary intervention (PCI). Methods: Totally, 71 patients who underwent PCI during 2nd week-6th month were randomly divided into the basic control group (group C，n＝38) and the observation group (group O，n＝33). Patients in group C maintained the basic medication, and those in group O received home-based exercise rehabilitation under the guidance of remote cardiogram monitoring in addition to the basic drug treatment. The follow-up time was 6 months. The changes in cardiopulmonary exercise capacity, left ventricular function, indicators reflecting the life quality including angina pectoris, anxiety, depression, and sleep quality were compared between the two groups before and after treatment. Results: Partial cardiopulmonary exercise indexes and left ventricular systolic function in group C were improved after treatment as compared with those before treatment (all P<0.05). All observed cardiopulmonary exercise indexes, left ventricular systolic and diastolic functions, scores of Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Pittsburgh Sleep Quality Index (PSQI) total score were significantly improved as compared with those before treatment (P<0.05, P<0.01). Among them, multiple cardiopulmonary exercise indexes, scores of SAQ, SAS, SDS and PSQI total scores in group O were significantly better than those in group C (P<0.05, P<0.01). There were no significant differences in the re-hospitalization rate and incidence of major cardiovascular adverse events within 6 months between the two groups. Conclusion: Home-based exercise rehabilitation under the guidance of remote cardiogram monitoring can effectively improve cardiopulmonary exercise capacity and left heart function, stabilize angina pectoris, reduce anxiety and depression, improve sleep quality, and thus improve the overall life quality of patients after PCI. |
