比索洛尔与卡维地洛对原发性高血压疗效及逆转左心室肥厚的对比研究

目的对比研究富马酸比索洛尔和卡维地洛治疗原发性高血压的疗效以及逆转左心室肥厚的作用。方法将106例原发性高血压伴左心室肥厚的患者随机分为富马酸比索洛尔组(49例)和卡维地洛组(46例),于服药前及服药后3、6及12个月分别监测两组患者血压、心率,并测定左心室舒张末内径、舒张期室间隔厚度、左心室后壁厚度、左心室射血分数、心排血量、A峰速度、E峰速度及A峰与E峰比值(A/E比值)。结果两组治疗后心率比治疗前减慢,差异有统计学意义(P0.05);富马酸比索洛尔组治疗后心率低于卡维地洛组,差异有统计学意义(P0.05)。两组治疗后随访3、6、9个月的血压均比治疗前降低,差异有统计学意义(P0.05)。两组治疗前后左心室射血分数、心排血量比较,差异无统计学意义(P0.05);两组治疗后A/E比值均比治疗前明显降低。两组左心室质量指数、左心室舒张末内径、舒张期室间隔厚度、左心室后壁厚度治疗后均比治疗前降低,差异有统计学意义(P0.05);富马酸比索洛尔组治疗后上述指标比卡维地洛组低,差异有统计学意义(P0.05)。结论富马酸比索洛尔和卡维地洛在降低血压的同时,均能改善左心室舒张功能,并明显减轻左心室肥厚;富马酸比索洛尔比卡维地洛减轻左心室肥厚效果更强,并可以有效控制心率。

Comparison of bisoprolol and carvedilol in antihypertensive effects and reversion of left ventricular hypertrophy in patients with essential hypertension

Objectives To compare the effects of anti-hypertension and reverse left ventricular hypertrophy by bisoprolol or carvedilol in patients with essential hypertension (EH). Methods One hundred and six EH patients with ventricular hypertrophy were divided into bisoprolol group (n=49) and carvedilol group (n=46) in random. Blood pressure,heart rate,left ventricular diastolic diameter (LVDd),interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),left ventricular ejection fraction...
