Nadolo剂量调整至降低心率25%,平均剂量为62 ± 25mg/d。中位随访时间为36月。每年行内镜检查1次。结局 事件为微小曲张静脉(F1)发展为大的曲张静脉(F2orF3) 。Nadolol组及placebo组结局事件发生率差异有统计学意义 (20%和51%,P < 0.001)。食管胃底静脉曲张破裂出血 率前者也低于后者(P = 0.02)。但生存率无差异。不良反应事 件发生前者多于后者(9vs1,P=0.01)

近几年的研究发现
预防静脉曲张发生——无效 “Beta-blockers to prevent gastroesophageal varices in patients with cirrhosis”
213 patients with cirrhosis and portal hypertension (minimal hepatic venous pressure gradient [HVPG] of 6 mm Hg)
临床疗效
许多临床研究表明非选择性beta受体阻滞剂预防肝硬 化门脉高压食管胃底静脉曲张的病人初次及再次曲张 静脉破裂出血有效。
