Abstract

Abstract:

Objective To explore the efficacy of a mobile patient-physician interactive platform for perioperative inspiratory muscle training（IMT） in patients undergoing heart valve replacement. Methods Using the convenient sampling method，a total of 124 patients who underwent cardiac valve replacement in the cardiovascular surgery department of a tertiary grade A hospital in Zhejiang Province from August 2023 to June 2024 were selected by convenience sampling and randomly divided into an experimental group and a control group using a random number table. The experimental group received IMT combined with a mobile patient-physician interaction platform，while the control group received conventional respiratory function exercise. Cardiopulmonary function indicators，frailty levels，cardiopulmonary function and postoperative pulmonary complications were compared between the two groups at discharge and during the one-month follow-up outpatient visit. Results A total of 122 patients were collected in this study，and one dropout each in the experimental and control groups. Patients who received mobile platform-based IMT showed significantly better frailty levels，cardiopulmonary function，and postoperative pulmonary complications at the one-month follow-up compared to the control group（P<0.05）. Additionally，interaction effects were observed in frailty score，grip strength，Five-Times Sit-to-Stand Test（FTSTS） and pulmonary function indicators（P<0.05）. Conclusion IMT delivered via a mobile patient-physician interaction platform improves cardiopulmonary function，reverses frailty，and reduces postoperative pulmonary complication rates in patients following heart valve replacement，offering a novel practical pathway for continuity of care during home-based rehabilitation.
