Coronary heart disease has remained the leading cause of death worldwide over the past decades. Unstable angina is a clinical syndrome intermediate in severity between stable angina and acute myocardial infarction with high morbidity and mortality. Standard drug therapy and invasive revascularization are effective in decreasing progression to infarction, reducing symptoms and multiple hospitalizations, in most cases without a decrease in the long-term mortality rate. However, there are still many patients with persistence or recurrence of angina despite standard medical therapy and/or revascularization. Wen Xin granule, as a Chinese herbal medicine has shown great effect in patients with unstable angina in our clinical. However, there is still insufficient evidence on his specific efficacy and safety. Therefor, we'd like to evaluate the efficacy and safety of Wen Xin granule in patients with unstable angina through this multi-center, double-blind, randomized placebo-controlled trial.
