GPT and cardiovascular disorder: Wang et al. analyzed the safety of YQFM on 106 elderly patients (≥80 years old) with cardiovascular diseases, and it was found that YQFM had little impact on the levels of serum alanine aminotransferase (ALT), AST, total bilirubin (TBil), and creatinine (Cr), and only one case (accounting for 0.94%) reported mild palpitation and precordial discomfort (Wang et al., 2018).
