Hemodynamic effect of carvedilol vs. propranolol in cirrhotic patients: Systematic review and meta-analysis.

BACKGROUND

Carvedilol appears to be more effective than propranolol in the treatment of portal hypertension in cirrhotic patients. Aim. To compare the effects of carvedilol vs. propranolol on systemic and splanchnic haemodynamics and to evaluate the adverse events associated with these treatments.

MATERIAL AND

METHODS

We performed a systematic review following the Cochrane and PRISMA recommendations. Randomised controlled trials comparing carvedilol versus propranolol, in the treatment of portal hypertension in cirrhotic patients with oesophageal varices, with or without bleeding history were included. The primary outcome measure was the haemodynamic response to treatment.

RESULTS

Four randomised trials and 153 patients were included; 79 patients received carvedilol (6.25-50 mg/d) and 74 patients received propranolol (10-320 mg/d). The hepatic vein pressure gradient (HVPG) decreased more with carvedilol than with propranolol (MD -2.21; 95% CI: -2.83 to -1.60, I(2) = 0%, P < 0.00001). Carvedilol was superior to propranolol for reducing HVPG by ≥ 20% from the baseline value or to ≤ 12 mmHg (OR: 2.93; 95% CI: 1.50 to 5.74, I(2) = 22%, P = 0.002). Overall adverse events did not differ between. In conclusion, there is limited evidence suggesting that carvedilol is more effective than propranolol for improving the haemodynamic response in cirrhotic patients with portal hypertension. Long-term randomized controlled trials are needed to confirm this information.
