Impaired cardiovascular responsiveness in liver disease.

Cardiovascular responsiveness to reflex impaired in patients with cirrhosis compared with control subjects. Peripheral vascular responses to exogenous noradrenaline were also impaired in cirrhotic patients, but peripheral vascular responses to infused adrenaline and to angiotensin II were similar in both groups. Impaired cardiovascular reactivity in patients with chronic liver disease could predispose them to circulatory failure after haemorrhage or surgery and should be considered when prescribing drugs which affect autonomic activity.
