Official Title: Doppler Ultrasound Hepatic Vein Waveform as a Non-invasive Tool in the Assessment of Severity of Portal Hypertension (DPH Trial)
Brief Summary: Portal hypertension is the result of an increased hepatic vascular resistance and portal inflow. The best established method to assess portal pressures is the determination of wedged hepatic venous pressure gradient (HVPG). Ultrasound Doppler technique is non-invasive in the assessment of portal hypertension as compared with invasive technique of measurement of the hepatic venous pressure gradient (HVPG). Hemodynamic measurements (BP and pulse recording) will be done and then patient will be given tablet Carvedilol 12.5 mg in a single dose and wait till the time that 20% reduction in heart rate from the baseline occurs. Haemodynamic measurements will be repeated to assess the acute response to beta-adrenoreceptor blocker agent. The change in the HWF will be recorded post beta-adrenoreceptor blocker administration.
