Hemodynamic effects of nifedipine on hepatic venous pressure gradient in patients with portal hypertension. 1986

A Straumann, and K Gyr, and W Kiowski, and H Bruendler, and G A Stalder

The effect of Nifedipine on hepatic venous pressure gradient (HVPG) was determined in 10 patients with portal hypertension due to cirrhosis of the liver, and in 7 control subjects, by hepatic vein catheterization. Twenty min. after sublingual application of 10 mg Nifedipine, patients and controls showed significant hemodynamic changes in the systemic circulation. In contrast, HVPG after Nifedipine was not statistically different from the basal values--neither in patients with portal hypertension (p = 16.6 +/- 5.2 mmHg vs 17.9 +/- 5.3 mmHg) nor in the control subjects (p = 2.9 +/- 1.1 mmHg vs. 1.0 mmHg). We conclude that calcium entry blockade by Nifedipine is not effective in acutely reducing portal venous pressure.
