Abstract

The present invention relates to a new use of 20(S)-protopanoxadiol, and in particular, to an application of 20(S)-protopanoxadiol in preparing the medicines for preventing and treating ischemic heart diseases. Pharmacodynamics studies have found that 20(S)-protopanoxadiol can reduce myocardial histological damages caused by ischemia and ischemia reperfusion, reduce enzyme indicators related to infarct size and myocardial necrosis, and reduce the drift of J-spot on an electrocardiogram.

Description

technical field [0001] The present invention relates to a new application of 20(S)-protopanaxadiol, in particular to the application of 20(S)-protopanaxadiol in the preparation of medicines for preventing and treating ischemic heart disease. Background technique [0002] In my country, cardiovascular disease (including hypertension and coronary heart disease) has become a major disease that endangers human health and life. In 2002, the mortality rate of heart disease among residents in big cities in my country was 75.68 per 100,000 people, ranking the third cause of death after malignant tumors and cerebrovascular accidents. [0003] Myocardial ischemic heart disease, also known as coronary heart disease, refers to heart disease caused by myocardial ischemia or hypoxia caused by coronary atherosclerosis, which narrows or blocks the lumen, and is caused by coronary atherosclerosis. The most common type of organ disease. Clinical manifestations include stable angina, unstabl...
