To assess the effect of Qingyu Jiuxi Pills (QYJXP) in the treatment of silent myocardial ischemia (SMI) in elder patients with coronary heart disease.
Randomized crossing self-controlled observation method was adopted. Fifty-eight patients were treated with QYJXP in treated period and isosorbide dinitrate (ISD) in control period.
Frequency and sustained time of SMI could be significantly reduced (P < 0.01) after the treatment of both QYJXP and ISD. The efficacy of QYJXP was better (P < 0.05) than that of ISD. No side effects were found in treating with QYJXP.
QYJXP is an effective and safe drug in treating SMI.
