Objective: Although telemedicine interventional therapy is an innovative method to reduce public medical burden and improve heart failure, its effectiveness is still controversial. This meta-analysis evaluates the role of telemedicine interventional therapy in the treatment of patients with chronic heart failure.

Methods: Relevant literature on telemedicine in chronic heart failure treatment was screened and extracted based on predefined criteria. Quality assessment used Cochrane Handbook 5.1.0 tool, and meta-analysis was conducted using R 4.2.2 software.

Results: Fifteen English-language articles were ultimately included in this meta-analysis. The risk bias evaluation determined that 4 articles were low-risk bias and 11 articles were unclear risk bias. The meta-analysis revealed that, compared to the routine intervention group, the all-cause hospitalization rate of patients in the telemedicine intervention group decreased [OR = 0.63, 95% CI (0.41; 0.96), P =.03], and the hospitalization rate of heart failure also decreased [OR = 0.70, 95% CI (0.48; 0.85), P <.01]. However, there were no differences in mortality [OR = 0.64, 95% CI (0.41; 1.01), P =.05], length of hospitalization [MD = -0.42, 95% CI (-1.22; 0.38), P =.31], number of emergency hospitalizations [MD = -0.09, 95% CI (-0.33; 0.15), P =.45], medication compliance [OR = 1.67, 95% CI (0.92; 3.02), P =.09], or MLHFQ scores [MD = -2.30, 95% CI (-6.16; 1.56), P =.24] among the patients.

Conclusion: This meta-analysis showed that telemedicine reduced overall and heart failure-related hospitalizations in chronic heart failure patients, suggesting its value in clinical management. However, it did not significantly affect mortality, hospital stay length, emergency visits, medication adherence, or quality of life. This suggests the need to optimize specific aspects of telemedicine, identify key components, and develop strategies for better treatment outcomes.
