Abstract

The invention discloses application of a P2X7 antagonist in preparation of medicament for treating myocardial ischemia injuries and hypertension/sympathetic nervous system diseases. Myocardial ischemia causes sympathetic excitoreflex (elevation of blood pressure, acceleration of heart rate and respiration and the like), and then myocardial ischemia injuries are aggravated. Cardiac sympathetic nervous erethism can also cause the elevation of blood pressure and then cause hypertension. The invention discloses a P2X7 receptor antagonist oxATP which can be used for reducing sympathetic nervous reflex caused by myocardial ischemia injuries and avoiding the phenomenon that myocardial ischemia and hypoxia are further aggravated due to cardiac sympathetic erethism, so that the myocardial ischemia injuries are relieved or alleviated. The hypertension can be prevented and cured by inhibiting cervical sympathetic ganglion erethism transmission. Sympathetic nervous diseases can be prevented and cured by inhibiting sympathetic erethism and related pathological processes. The mechanism of action of the oxATP in preventing and treating myocardial ischemia injuries, hypertension and sympathetic nervous lesions is as follows: the sympathetic excitation transmission mediated by cervical sympathetic ganglion P2X7 accepter is blocked, and an effect of preventing and treating the myocardial ischemia injuries, hypertension and sympathetic nervous diseases is generated.

Description

technical field [0001] The invention belongs to the technical field of inventions for use of medicines, and relates to inventions for uses of medicines for myocardial ischemia injury and hypertension / sympathetic nervous system diseases. Background technique [0002] Acute myocardial ischemia is usually caused by an imbalance between myocardial oxygen demand and oxygen supply caused by coronary artery occlusion or impending occlusion. Acute coronary syndrome refers to a series of symptoms caused by acute myocardial ischemia, including myocardial infarction (ST-segment elevation and depression, Q wave type and no Q wave type) and unstable angina. Clinical studies have found that angina symptoms in 50-60% of patients with coronary heart disease can disappear after resection of sympathetic ganglia such as superior cervical ganglion (SCG) and stellate ganglion (SG), suggesting that the innervation of the heart Sympathetic involvement in myocardial ischemic injury response. The ...
