Guanxinjing capsule in the treatment of chronic stable angina: study protocol for a randomized controlled trial
Abstract Background Stable angina is a common cardiovascular disease with high mortality and a poor prognosis. Although there are various interventions against stable angina, none are able to significantly reduce the mortality rate. Guanxinjing capsule (GXJ) is made from the classical Chinese prescr...
