[Abstract] Objective To investigate effects of hyperhomocysteinemia to early renal function in prehypertention.Methods Convenient selection 169 prehypertensive patients and 57 normotensive control subjects (NC group) were evaluated. All prehypertensives were divided into 2 groups: prehypertensives with hyperhomocysteinemia (HHcy) (HHcy group, n=107) and prehypertensives without hyperhomocysteinemia (NHHcy group, n=62). Homocysteine (Hcy), albumin/creatinine ratio (UACR), and glomerular filtration rate (GFR) were assessed in all subjects. And compared the differences of above indicators between all groups, and analyzed effects of hyperhomocysteinemia to early renal index UACR and GFR in prehypertention Results Hypertensive patients had the higher prevalence of HHcy and blood pressure than NC group. Compared with NC group and NHHcy group, improved Hcy and UACR while reduced GFR were found in HHcy group significantly(P<0.05). Finally, correlation analysis showed that Hcy was positive associated with UACR (r=0.485,P<0.01), while was negative associated with GFR(r=-0.348, P<0.01).Conclusion Prehypertensive patients with HHcy had early damage of renal function and higher blood pressure. Increased Hcy can be used as a alternative target for preventing target organ damage and delaying the process of blood pressure.

高血壓前期是指血壓介于正常血壓和高血壓之間的一種中間狀態(tài),是臨床高血壓和一系列與血壓增高相關(guān)的心血管事件的前期。我國35~64歲人群中高血壓前期占32.1%,與高血壓的比例為1.2∶1.0[1]。高同型半胱氨酸血癥(hyperhomocysteinemia,HHcy)是指血同型半胱氨酸(homocysteine,Hcy)超過10 mol/L[2]。Hcy促進高血壓的進展,損傷腎功能,是心腦血管疾病的獨立危險因素。該文方便選取該院自2014年8月—2015年12月,高血壓前期169例及血壓正常57例為研究對象。測定所有受試者同型半胱氨酸(Hcy)、尿微量白蛋白/肌酐(UACR)和腎小球濾過率(GFR)等指標,并比較各組上述指標的差異,現(xiàn)報道如下。……
