Purpose
Study hypothesis:
Hepatic venous pressure gradient (HVPG)-directed primary prophylaxis with nonselective beta-blocker therapy (NSBB) leads to a reduction in first variceal bleeding episodes and is cost-effective in the long term.
Study design:
A multi-center randomized controlled study comparing nonselective beta-blocker therapy guided by the hemodynamic response as determined by the difference in HVPG before and after starting oral NSBB therapy, to standard heart rate-guided NSBB therapy in patients with esophageal varices due to liver cirrhosis without a history of esophageal variceal hemorrhage.
Primary study parameters/outcome of the study:
First variceal bleeding episodes occurring within the first two years.
Secondary study parameters/outcome of the study:
- Mortality
- Occurrence of other cirrhosis-related complications
- Occurrence of hepatocellular carcinoma
- Costs of treatments
- Adverse effects

| Arms | Assigned Interventions |
|---|---|
| Experimental: HVPG-propranolol arm |
Procedure: Hepatic venous pressure gradient measurement
Perform baseline HVPG measurement, then start propranolol 20 mg orally twice daily (BID), increase the dose stepwise to maximum tolerated dose. After 4 weeks a second HVPG is performed. In hemodynamic nonresponders from the study arm, repeated endoscopic band ligation is performed in daycare setting with intervals of 2-4 weeks. In hemodynamic responders (HVPG second measurement< 12 mmHg or >20% reduction in HVPG compared to baseline) beta-blockers are continued until end of follow-up. Other Names:
|
| No Intervention: Propranolol arm |
Other: standard of care primary prevention with propranolol
In control group: Start propranolol 20 mg BID, increase the dose stepwise with 3 days interval to maximum heart rate-guided tolerated dose.
Other Name: Propranolol
