Abstract: Objective To summarize the best evidence of cardiac rehabilitation of patients after heart valve replacement and to provide reference for domestic cardiac rehabilitation. Methods With questions developed by PIPOST, a rigorous search strategy, inclusion criteria and exclusion criteria were developed, we searched original research for evidence of cardiac rehabilitation in adult patients after heart valve replacement, and extracted the evidence of the literatures meeting the quality standards. Two researchers used the corresponding evaluation tools to conduct quality evaluation, evidence extraction and synthesis independently. Results Nine studies were found, including three clinical practice guidelines, one systematic review, three RCTs, one CCT and one consensus. Totally 20 items of evidence were summarized and five dimensions including assessment, comprehensive respiratory function training, periodic sport training, sport observation and health education and 17 items of best evidence were extracted. Conclusion Nursing administrators should strengthen education on cardiac rehabilitation among nurses,when choosing the best evidence, clinical environment, professional judgment of nurses and patients' willingness should be taken into consideration.
