【摘 要】高血压作为一种常见病严重威胁着人们的健康,近几年,针对高血压危险因素国内外学者提出H型高血压的概念,即伴有同型半胱氨酸水平升高(Hcy>10umol/l)的高血压,以此水平,H型高血压约占我国高血压患者的75﹪。研究显示同型半胱氨酸对血管内皮细胞具有毒性作用,致动脉硬化作用明显,H型高血压患者因具有高血压及高同型半胱氨酸双重致动脉硬化危险因素,对于心脑血管疾病的危险作用显著,因此逐渐受到重视,积极防治H型高血压对于心脑血管疾病的预防具有重要意义。

The correlation between H-type hypertension and cardiovascular
and cerebrovascular diseases

【Abstract】Hypertension , as a kind of common disease threat to people's health seriously.In recent years, according to the risk factors for high blood pressure, scholars at home and abroad put forward the concept of H-type hypertension, which is associated with elevated homocysteine levels (Hcy > 10 umol/l) of high blood pressure. As to this level, H-type hypertension accounted for about 75 percent of the patients with hypertension in our country. Studies have shown that homocysteine has toxic effect on vascular endothelial cells, so it has significant effect on atherosclerosis. H-type hypertension due to have high blood pressure and high homocysteine double risk factors that cause atherosclerosis, thus should be taken seriously gradually. The active prevention and treatment of H-type hypertension is of great significance for cardiovascular and cerebrovascular diseases

高血压是一种常见病、多发病,严重威胁着人类的健康,随着社会经济的发展及人们生活方式的改变,我国人群高血压患病率呈逐年增长趋势。大量研究已确定高血压的发病主要与肥胖、高盐膳食及中度以上饮酒等传统危险因素有关,同时高血压也具有一定的遗传基础。2010版《中国高血压防治指南》中高血压危险因素中增加了“糖耐量受损和(或)空腹血糖调节受损”,同时同型半胱氨酸(homocysteine Hcy)作为一种新的危险因素也纳入高血压分层中[1]。因此Hcy作为一种新发现的高血压危险因素逐渐受到国内外专家学者的重视。因Hcy具有致动脉硬化作用,高血压也为动脉硬化的独立危险因素,因此H型高血压与心脑血管疾病的发病具有显著相关性。
