Curative Effect Evaluation of Danlou Tablet on Coronary Artery Disease Not Amenable to Revascularization

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether Danlou Tablet is effective in the treatment of coronary artery disease not amenable to revascularization on the basis of western medicine therapy.

Detailed Description
-----------------
The western medicine treatment for CAD not amenable to revascularization is limited. Danlou Tablet, a kind of Chinese patent medicine has been used for treating coronary artery disease in clinical practice in China for many years. Danlou Tablet is applicable to phlegm-stasis syndrome in Traditional Chinese Medicine. According to recent studies, Danlou Tablet can reduce blood lipid level and myocardial necrosis area ,promote infarct healing in rats.And it can improve clinical symptoms of patients with CAD.
