The effects on portal pressure of the vasodilatory drugs isosorbide dinitrate and verapamil and of an alpha and beta blocking agent, labetalol, were assessed in 21 patients with cirrhosis and portal hypertension. The wedged hepatic venous pressure gradient (wedged minus free hepatic venous pressures) was used as an index of portal pressure and was not significantly changed by treatment with labetalol (n = 5) but was significantly decreased by verapamil (n = 6; p less than 0.05) and isosorbide dinitrate (n = 10; p less than 0.01). Long term administration of isosorbide dinitrate also had a significant effect (p less than 0.01).
在21例肝硬化和门静脉高压患者中评估了血管扩张剂硝酸异山梨酯和维拉帕米以及α和β阻滞剂拉贝洛尔对门静脉压力的影响。肝静脉楔压梯度(肝静脉楔压减去自由肝静脉压)用作门静脉压力指标,拉贝洛尔治疗(n = 5)对其无显著影响,但维拉帕米(n = 6;p < 0.05)和硝酸异山梨酯(n = 10;p < 0.01)使其显著降低。长期给予硝酸异山梨酯也有显著效果(p < 0.01)。
