What is the methodological and reporting quality of systematic reviews evaluating traditional Chinese medicine for myocardial infarction?
What is the methodological and reporting quality of systematic reviews evaluating traditional Chinese medicine for myocardial infarction?
The methodological and reporting quality of systematic reviews on traditional Chinese medicine for myocardial infarction is poor, limiting evidence for its therapeutic value.
Insufficient evidence precludes recommending traditional Chinese medicine for myocardial infarction; leaves open any benefit pending rigorous trials.
OBJECTIVES: This overreview aimed to evaluate the methodological quality and reporting quality of the systematic reviews of Chinese herbal medicine. METHODS: Electronic literature databases, including the PubMed, Embase, Cochrane library two Chinese databases (China National Knowledge Internet and Wanfang database) from inception to November 2011 were searched. Systematic reviews and Meta-analyses of the Chinese medicine for myocardial infarction were included. Data were extracted by two independent reviewers. AMSTAR (Assessment of Multiple Systematic Reviews) and PRIMSMA Preferred Reporting Items for Systematic Reviews and Meta-Analysis were used to assess the methodological and reporting quality of the included systematic reviews. RESULTS: Ten reviews were included. One SR was concerned with ventricular remodelling after myocardial infarction, one was concerned with hypotension after myocardial infarction, and the rest related to the myocardial infarction. The interpretation of the included systematic reviews was poor. CONCLUSIONS: A number of systematic reviews have become available, but the therapeutic value of traditional Chinese medicine remains limited.

Dong-mei et al. (2013) conducted a review in myocardial infarction (n=10). Traditional Chinese medicine was evaluated on Methodological and reporting quality. Traditional Chinese medicine for myocardial infarction was evaluated in 10 systematic reviews, revealing poor methodological interpretation and limited evidence of therapeutic value.
