Background: A reduced prevalence of cardiovascular diseases has been reported in liver cirrhosis. However, studies focusing on supraortic district of cirrhotic patients are lacking. Methods: By ultrasound duplex scanning, the presence and severity of atherosclerotic plaques and flow pattern abnormalities were assessed in carotid and vertebral arteries of 118 cirrhotics aged 60.7 12.8 (1 standard deviation) years, and in 236 controls matched with cirrhotic patients according to age, sex and cigarette smoking. Results: Previous ischemic strokes were significantly less numerous in cirrhotic patients than in controls (0.8% vs. 10.5%; P50.0009); also the prevalence of myocardial infarction was significantly reduced (1.7% vs. 6.4%; P50.0532). Moreover, cirrhotic patients differed from controls for a lower prevalence of hypertension and hypercholesterolemia, and for a greater proportion of diabetics. Although the presence and severity of atherosclerotic plaques was similar in the two groups, liver cirrhosis was associated with a lower prevalence of abnormal flow patterns (13.6% vs. 29.2%; P50.0011). The inverse association of hemodynamic changes with liver cirrhosis persisted after all main risk factors were simultaneously taken into account by multiple logistic regression. However, in the presence of hypertension, hypercholesterolemia and cigarette smoking, the ‘protective’ effect of cirrhosis on the occurrence of abnormal flow patterns was no longer detectable. Conclusions: Advanced liver disease is associated with a reduced prevalence of ischemic stroke, which seems to be related to a decreased prevalence of abnormal flow patterns in the supraortic vessels, especially among non-smokers

Abstract

Background: A reduced prevalence of cardiovascular diseases has been reported in liver cirrhosis. However, studies focusing on supraortic district of cirrhotic patients are lacking. Methods: By ultrasound duplex scanning, the presence and severity of atherosclerotic plaques and flow pattern abnormalities were assessed in carotid and vertebral arteries of 118 cirrhotics aged 60.7 12.8 (1 standard deviation) years, and in 236 controls matched with cirrhotic patients according to age, sex and cigarette smoking. Results: Previous ischemic strokes were significantly less numerous in cirrhotic patients than in controls (0.8% vs. 10.5%; P50.0009); also the prevalence of myocardial infarction was significantly reduced (1.7% vs. 6.4%; P50.0532). Moreover, cirrhotic patients differed from controls for a lower prevalence of hypertension and hypercholesterolemia, and for a greater proportion of diabetics. Although the presence and severity of atherosclerotic plaques was similar in the two groups, liver cirrhosis was associated with a lower prevalence of abnormal flow patterns (13.6% vs. 29.2%; P50.0011). The inverse association of hemodynamic changes with liver cirrhosis persisted after all main risk factors were simultaneously taken into account by multiple logistic regression. However, in the presence of hypertension, hypercholesterolemia and cigarette smoking, the ‘protective’ effect of cirrhosis on the occurrence of abnormal flow patterns was no longer detectable. Conclusions: Advanced liver disease is associated with a reduced prevalence of ischemic stroke, which seems to be related to a decreased prevalence of abnormal flow patterns in the supraortic vessels, especially among non-smokers
