原发性高血压的发病机制尚未完全阐明,目前认为下列因素在发病中有重要作用:1、交感神经兴奋、儿茶酚胺类活性物质分泌增加致心输出量及周围血管阻力增加;2、肾功能异常导致水钠潴留和血容量增加,肾素分泌异常,肾素-血管紧张素-醛固酮系统调节失常3、内分泌因素,肾上腺髓质激素分泌增加,其中去甲肾上腺素引起周围小动脉收缩,肾上腺素则增加心排血量均可使血压升高4、其他,缓激肽、前列腺素代谢异常及遗传、肥胖、摄钠过多、饮酒等因素,均能导致心输出量及外周血管阻力增加,因而引起血压升高

The pathogenesis of essential hypertension has not been fully clarified,the following factors currently considered to play an important role in the pathogenesis:1,sympathetic nerve activity,increased secretion of catecholamines caused by active substances cardiac output and peripheral vascular resistance increased; 2,renal dysfunction Shuinazhuliu and blood volume lead to increased renin secretion abnormal renin - angiotensin - aldosterone system dysregulation 3,endocrine factors,increased secretion of adrenal medulla hormones,including norepinephrine induced contraction of small arteries around,epinephrine increased blood pressure,cardiac output can be increased to 4,the other,bradykinin,prostaglandins,and genetic metabolic disorders,obesity,excessive sodium intake,alcohol consumption and other factors,can lead to cardiac output and increased peripheral vascular resistance ,thus causing high blood pressure
