研究目的: |
基于N5,N10-亚甲基四氢叶酸还原酶(MTHFR)C677C/T基因多态性,探讨叶酸联合维生素B12辅助两种基础降压方案(苯磺酸氨氯地平联合阿托伐他汀 vs 非洛地平缓释片联合马来酸依那普利叶酸片)对慢性肾衰竭维持性透析(MHD)合并高血压(HTN)且确诊为冠心病患者的血同型半胱氨酸(Hcy)、血压、血压变异性(BPV)、血管内皮功能及心功能(BNP)的调控效果,筛选最优治疗组合。 |

|
Objectives of Study: |
Objective To explore the regulatory effect of folic acid combined with vitamin B12 adjuvant to two basic antihypertensive regimens (amlodipine besylate + atorvastatin vs felodipine sustained-release tablets + enalapril maleate folate tablets) on blood homocysteine (Hcy), blood pressure, blood pressure variability (BPV), vascular endothelial function, and cardiac function (BNP) in maintenance hemodialysis (MHD) patients with hypertension (HTN) and coronary heart disease (CHD), based on N5,N10-methylenetetrahydrofolate reductase (MTHFR) C677C/T gene polymorphism, and to screen the optimal treatment combination. |
