Evidence synthesis outlines 42 recommendations for Phase II cardiac rehabilitation post-CRT in DCM.
Why the study?
A systematic summary of available evidence on Phase II exercise-based CR for patients with DCM after CRT was needed to provide an evidence-based framework for clinical nursing practice.
Does Phase II exercise-based cardiac rehabilitation improve cardiorespiratory function and quality of life in adults aged ≥18 years with dilated cardiomyopathy who have undergone cardiac resynchronization therapy?
Does Phase II exercise-based cardiac rehabilitation improve cardiorespiratory function and quality of life in adults aged ≥18 years with dilated cardiomyopathy who have undergone cardiac resynchronization therapy?
This evidence summary synthesizes 42 recommendations across 12 themes from 28 publications to provide a structured framework for Phase II exercise-based cardiac rehabilitation in patients with dilated cardiomyopathy after cardiac resynchronization therapy.

Supports Phase II CR guidance post-CRT in DCM via 12 themes; extends general HF evidence but direct data remain limited.
Background: This study aimed to systematically summarize the available evidence on Phase II exercise-based cardiac rehabilitation (CR) for patients with dilated cardiomyopathy (DCM) after cardiac resynchronization therapy (CRT), so as to provide an evidence-based framework for clinical nursing practice. Methods: A comprehensive computerized search was conducted in PubMed, Embase, Cochrane Library, CINAHL, Web of Science, CNKI, WanFang, VIP, and SinoMed, as well as guideline repositories, evidence-based databases, and professional association websites. The included document types were clinical decisions, guidelines, expert consensus or consensus documents, evidence summaries and systematic reviews. Results: Twenty-eight publications were included: 2 clinical decisions, 10 guidelines, 1 systematic review, 11 expert consensus or consensus documents and 4 evidence summaries. A total of 42 pieces of evidence items were summarized across 12 themes: multidisciplinary collaboration, indications and contraindications for exercise rehabilitation, pre-exercise assessment, pre-exercise preparation, exercise prescription, aerobic exercise, resistance training; pulmonary rehabilitation training, flexibility training, personalized adjustment, remote supervision and support, and emergency management. Conclusion: This study synthesized available evidence on Phase II exercise-based CR for patients with DCM after CRT. Most included evidence was derived from broader heart failure or cardiac rehabilitation populations; direct evidence specific to DCM after CRT remains limited. These findings may inform the development of individualized rehabilitation protocols, but recommendations should be applied with caution. Registration: This evidence summary was registered with the Fudan University Center for Evidence-Based Nursing (Registration No. ES202610091).

Wang et al. (2026) conducted a review in Dilated cardiomyopathy after cardiac resynchronization therapy. Phase II exercise-based cardiac rehabilitation was evaluated on Evidence synthesis of Phase II exercise-based cardiac rehabilitation recommendations. Phase II exercise-based cardiac rehabilitation post-CRT in dilated cardiomyopathy was synthesized into 42 evidence items across 12 themes from 28 publications.
