原发性高血压患者血压水平与早期肾损害的相关性研究

   【摘要】  目的 探讨原发性高血压患者脉压(PP)、SBP、DBP及平均动脉压(MAP)与早期肾损害的关系。方法 选择180例初诊或停药2周以上的原发性高血压患者进行PP、SBP、DBP和MAP检查,以血β2微球蛋白(β2?MG)水平>2.6 mg/L作为肾损害的标准,分为肾损害组和非肾损害组,其中肾损害组84例,非肾损害组96例。将两组血压参数进行比较,并与血β2?MG水平进行相关性分析。结果 (1)肾损害组PP[(59±10) mmHg]及SBP[(168±28) mmHg]较非肾损害组[(41±8) mmHg,(151±10) mmHg]明显增高。(2)相关分析显示血β2?MG与PP、SBP呈正相关,尿β2?MG与PP、SBP、DBP、MAP呈正相关。其中与PP、SBP相关性较好。结论 PP与SBP、DBP、MAP增高均可导致高血压患者早期肾损害,而PP、SBP增大是导致高血压患者早期肾损害的主要因素。

    【Abstract】  Objective  To investigate the relationship between different blood pressure parameters and early renal impairment in patients with essential hypertension (EH). Methods  SBP, DBP, pulse pressure (PP) and mean arterial pressure (MAP) were measured in 180 new diagnosed patients with EH. Of whom, 84 patients were assigned to early renal impairment group using the criteria of serum concentration of β2?microglobulin (β2?MG)>2.6 mg/L. The remaining 96 patients were served as normal renal function group. Results  PP and SBP were significantly higher in early renal impairment group than in normal renal function group. Blood β2?MG was positively correlated with PP and SBP, urine β2?MG was positively correlated with PP, SBP, DBP and MAP. Conclusions  PP, SBP, DBP and MAP were all risk factors for early renal impairment. PP and SBP were most important factors associated with early renal impairment.

    原发性高血压是最常见的心血管疾病之一,易导致心、脑、肾等靶器官损害。国外流行病学研究表明,脉压(pulse pressure, PP)、SBP、DBP、平均动脉压(MAP)是心脑血管疾病的预测因子[1?2]。近年来,单一的SBP、DBP、MAP、PP与肾损害已有报道,但是这4个指标同步进行研究,哪个指标对肾损害影响最大尚未见报道。本研究测定血、尿β2微球蛋白(β2 microglobulin,β2?MG)水平,旨在探讨原发性高血压患者的PP、SBP、DBP、MAP与早期肾损害的关系,为有效控制高血压及其并发症提供有效依据。
