摘要:
目的:探讨缬沙坦(Valsartan,Val)对高血压病左室肥厚(LVH)患者左室质量指数(LVMI)、心率校正的QT离散度(QTcd)及室性心律失常(VA)的影响。方法:高血压病LVH患者共55例,随机分为常规治疗组(Rou组,n=30),缬沙坦治疗组(Val组,n=25)。两组分别于治疗前、治疗1年后用彩色多普勒Penn法测定LVMI,分析体表标准12导联心电图QTcd并用Holter记录VA发生的情况。结果:LVH患者LVMI与QTcd间有显著相关性(r=0.36,P<0.01)。Rou组治疗前后LVMI为150±16g·m-2vs149±16g·m-2(P>0.05);Val组治疗前、后LVMI为152±17g·m-2vs139±15g·m-2(P<0.01)。Rou组治疗前后QTcd为74±12msvs72±12ms(P >0.05),Val组治疗前后QTcd为73±12msvs65±9ms(P<0.05)。治疗前Rou组与Val组间QTcd无显著性差异(P>0.05),治疗后两组间QTcd存在显著性差异(P<0.05)。Rou组及Val组治疗前VA恶性程度无显著性差异(P>0.05),治疗后两组间VA恶性程度比较有显著性差异(P<0.05)。结论:Val治疗可显著降低LVMI和QTcd,从而降低VA的恶性程度。
Abstract:
AIM:To investigate the effect of valsartan(Val) on left ventricular mass index (LVMI), heart rate corrected QT interval dispersion (QTcd) and ventricular arrhythmia(VA) in patients with left ventricular hypertrophy (LVH) caused by essential hypertension.METHODS: 55 hypertension patients with LVH were divided randomly into two groups.30 patients in Rou group were treated routinely.25 patients in Val group were treated with routine drugs plus val. LVMI,QTcd of 12-lead surface ECG and VA malignant degree recorded by Holter were analyzed before and 1 year after the therapy.RESULTS:In the Rou group,the change of QTcd before and after the therapy was not significant(74±12msvs72±12ms,P>0.05).In the Val group,the change of QTcd was significant before and after the therapy (73±12msvs65±9ms,P<0.05). Before the therapy QTcd and the malignant degree of VA between the two groups were not significantly different. But both of the two indexes between the two groups were significantly different after the therapy.CONCLUSION:Treatment with Val can significantly reduce the QTcd and the malignant degree of VA in patients with LVH caused by hypertension
