Abstract

The invention discloses a medicinal composition for treating cardiovascular diseases and a preparation method thereof. The medicinal composition is prepared from the following active pharmaceutical ingredients: ginseng stem and leaf, ginkgo leaf, total saponin extract of ginseng stem and leaf, and ginkgo leaf extract. The medicinal composition can effectively resist rat infarction and myocardial ischemia injury of acute myocardial infarction, reduce the myocardial infarction area, enhance the hypoxia resistance of cardiac muscles, improve the function of vascular endothelium and resist arterial thrombosis. The synergic experiment indicates that the active pharmaceutical ingredients (ginseng stem and leaf and ginkgo leaf) medicinal composition have an synergic action, and have much better effect as compared with single ginseng stem and leaf or ginkgo leaf. The medicinal composition has the advantages of low toxicity, high safety and high stability.

Description

field of invention [0001] The invention relates to a pharmaceutical composition and a preparation method thereof, in particular to a pharmaceutical composition for treating cardiovascular diseases and a preparation method thereof. Background technique [0002] Angina pectoris of coronary heart disease is a clinical syndrome caused by temporary myocardial ischemia and hypoxia, with episodic chest pain or chest discomfort as the main manifestation. Angina pectoris often occurs when labor, emotional agitation or other factors increase myocardial oxygen consumption. The pain can often radiate to the left shoulder, neck pharynx or mandible, and can be relieved within a few minutes by rest or nitroglycerin. During the onset of angina pectoris, the electrocardiogram often shows temporary ST segment changes or accompanied by T wave changes, and coronary angiography shows narrowing of the coronary artery lumen. [0003] In the 1980s, the development and popularization of interventio...
