Abstract: ［Abstract］ Objective〖HTSS〗〓To investigate the relationship between H type hypertension and coronary heart disease(CHD).
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The 357 patients who were hospitalized in the department of cardiology and underwent coronary angiography examination were collected. According to the results of coronary angiography, they were divided into CHD group and non CHD group. plasma homocysteine(Hcy) values was determinated. Based on plasma Hcy value, basal blood pressure and coronary angiography results, we investigated the relationship between H type hypertension and CHD.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The Hcy level of the CHD group was significantly higher than the non CHD group(P＜005). The incidence of high Hcy, hypertension and H hypertension of the CHD group were higher than the non CHD group, the differences were statistically significant(P＜005). The homocysteine level and Gensini score of the AMI group were significantly higher than the SAP and UAP group. The differences were significant(P＜005). Hcy single factor correlation analysis showed that the Hcy level  was correlated with Gensini score, and the difference was statistically significant(r=0743, P=0000), through multiple regression analysis, the H type hypertension was selected as one of the CHD. Other independent risk factors were not independent risk factors for CHD.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The level of Hcy in patients with CHD is higher than that of the non CHD. H type hypertension is an independent risk factor for coronary heart disease.
