摘要 目的观察厄贝沙坦氢氯噻嗪片对中老年原发性高血压患者血压晨峰(MBPS)及左心室质量(LVM)相关参数的影响。方法选择120例轻中度原发性高血压患者,口服厄贝沙坦氢氯噻嗪片150mg/12.5mg,4-8周不达标者剂量加倍,治疗12个月,应用动态血压监测(ABPM)评价治疗前后MBPS的变化,应用超声心动图评价LVM相关参数的变化。结果(1)经厄贝沙坦氢氯噻嗪片治疗后,MBPS(+)的患者减少,MBPs(-)的患者增多,与治疗前比较差异有统计学意义(P〈0.01)。(2)治疗后MBPS(+)患者晨峰程度较治疗前明显降低[收缩压(SBP)差值(16.1±1.8)mmHg(1mmHg=0.133kPa)比(29.4±2.8)mmHg,舒张压(DBP)差值(10.2±2.3)mmHg比(21.2±2.2)mmHg,P〈0.01],而MBPS(-)患者晨峰程度较治疗前无明显下降[SBP差值(11.2±2.4)mmHg比(10.1±1.2)mmHg,DBP差值(5.9±1.9)mmHg比(6.8±3.2)mmHg]。(3)MBPs(+)和MBPS(-)患者治疗后LVM相关参数较治疗前均明显减小,且MBPs(+)患者治疗后左心室后壁厚度、LVM、LVM指数与MBPS(-)患者治疗后比较差异有统计学意义(P〈0.05)。结论厄贝沙坦氢氯噻嗪片能有效遏制MBPS的发生,降低晨峰程度,并能逆转左心室肥厚。 Objective To investigate the influence of combined irbesartan/hydrochlorothiazide on morning blood pressure surge (MBPS) and left ventricular mass (LVM) in essential hypertension. Methods After 4-8 weeks' run-in period,if blood pressure wasn't up to the standard,the 120 patients were given irbesartan/hydrochlomthiazide once daily from 150 rag/12.5 mg for 12 months to 300 mg/25mg for another 12 months. MBPS was conducted by ambulary blood pressure monitoring (ABPM) and LVM was determined by echocardiography at the end of placebo baseline and 12 months later. Results (1)After treatment the patients with MBPS(+) decreased and patients with MBPS(-) increased. (2) After treatment the extents of MBPS were reduced in MBPS(+) patients[systolic blood pressure (SBP) difference (16.1±1.8) mm Hg(1 mm Hg =0.133 kPa) vs (29.4±2.8) mm Hg,diastolic blood pressure (DBP) difference (10.2±2.3) mm Hg vs (21.2±2.2) mm Hg, P 〈 0.01 ] with little change in MBPS (-) patients [ SBP difference (11.2±2.4) mm Hg vs(10.1±1.2) mm Hg,DBP difference (5.9±1.9) mm Hgvs (6.8±3.2) mm Hg] compared with before treatment. (3) LVM indexes of all patients were significantly reduced. Conclusion Irbesartan/ hydrochlorothiazide can effectively attenuate the extent of MBPS, and has advantages on reversing left ventricular hypertrophy.
