Acute and chronic hemodynamic effects of propranolol in unselected cirrhotic patients

Different and contradictory results concerning the use of propranolol in the treatment of portal hypertension have been reported. This study was designed to investigate the hemodynamic effects of short- and long-term administration of propranolol in portal hypertensive patients. Portal pressure, cardiac index, heart rate and blood pressure were obtained in 18 unselected alcoholic cirrhotic patients with esophageal varices before and 60 min after the oral administration of 40 mg propranolol and again after 106 +/- 35 days of continuous oral administration (mean dose = 158 +/- 63 mg per day). Baseline portal pressure was 21.7 +/- 7.2 mm Hg. It decreased after 60 min to 17.2 +/- 5.5 mm Hg (p less than 0.01) and after long-term administration of propranolol to 16.1 +/- 5.7 mm Hg (p less than 0.01). No decrease in portal pressure was noted in 9 of 18 (50%) patients after acute administration and 5 of 17 (30%) patients after long-term administration. Baseline cardiac index was 5.1 +/- 1.2 liters X min-1 X m-2. It decreased after 60 min to 3.9 +/- 1.4 liters X min-1 X m-2 (p less than 0.01) and to 3.6 +/- 1.0 liters X min-1 X m-2 after long-term administration (p less than 0.001). Baseline heart rate was 85 +/- 11 beats per min. It decreased after 60 min to 75 +/- 9 (p less than 0.001) and after long-term administration to 62 +/- 6 (p less than 0.001) beats per min. Baseline mean arterial pressure was 108 +/- 11 Hg. It decreased after 60 min to 97 +/- 14 mm Hg (p less than 0.01) and after long-term administration to 103 +/- 14 mm Hg (not statistically significant).(ABSTRACT TRUNCATED AT 250 WORDS)
