Hvpg represents gradient b/w sinusoidal pressure &I've pressure

hvpg represents gradient b/w sinusoidal pressure &I’ve pressure OR portal vein pressure & ivc pressure
&Sir is it necessary to have increased hpvg in portal hypertension

The normal HVPG value is between 1 to 5 mmHg. Pressure higher than this defines the presence of portal hypertension, regardless of clinical evidence. HVPG >or= 10 mmHg (termed clinically significant portal hypertension) is predictive of the development of complications of cirrhosis, including death.

Thank you.
