Propranolol for prevention of recurrent gastrointestinal bleeding in patients with cirrhosis: A prospective study of factors associated with rebleeding
Abstract
In a previous randomized trial, we demonstrated that propranolol prevented recurrent gastrointestinal bleeding in patients with cirrhosis. We have undertaken the present study in a new group of patients to ascertain the factors associated with rebleeding. Among 232 patients with cirrhosis admitted for gastrointestinal bleeding, 127 were included. They received propranolol orally at a dose reducing the heart rate by 25%. The median follow-up period was 682 days. The following factors were studied: cause of cirrhosis; severity of cirrhosis; hepatocellular carcinoma recognized after inclusion; compliance; persistent decrease in heart rate; dose of propranolol; alcohol abstinence; previous history of hemorrhage; time interval from hemorrhage to onset of propranolol administration, and source of bleeding. The percentage of patients free of rebleeding was 71% at 1 year and 57% at 2 years. Only five factors were significantly and independently associated with rebleeding: occurrence of hepatocellular carcinoma; lack of compliance; lack of persistent decrease in heart rate; lack of abstinence, and previous history of bleeding. In conclusion, this study confirms the results of our previous trial and suggests that certain factors play a role in the mechanism of rebleeding in patients receiving propranolol.
