AIM: To study heart structure and function parameters and hepatolienal blood flow in patients with virus-induced cirrhosis (VIC).
MATERIALS AND METHODS: 95 patients with VIC (mean age, 38.6; disease duration, 4.5 years) were evaluated. Doppler EchoCG and Doppler ultrasonic examination of hepatolienal vasculature (VIVID E 95 apparatus) were performed. The control group consisted of 19 healthy individuals. Statistical analysis was performed using the Statistica 6.0 software.
RESULTS: The study of hepatolienal blood flow showed that the splanchnic artery blood flow velocity was increased by 25%, the hepatic vein blood flow velocity was increased by 13%, and splanchnic arteries and veins were dilated. 24% of VIC patients had moderate pulmonary hypertension associated with a 20% dilatation of inferior vena cava (p=0.007), a 28% increase in hepatic vein blood flow velocity (p=0.0003), and a 13% decrease in portal vein diameter (p=0.001). Four types of left ventricular (LV) geometry were identified: 40% of VIC patients had normal geometry; 17% of patients had concentric hypertrophy; 23% of patients had concentric remodeling; and 19% had eccentric hypertrophy. Features of hepatolienal blood flow were related with the LV geometry type. LV diastolic filling was impaired in 44.3% and RV diastolic filling - in 33% of patients. In patients with VIC, the disturbed diastolic function was associated with 25% reduced hepatic vein blood flow velocity (p=0.05) whereas development of RV diastolic dysfunction was associated with 6% reduced portal vein diameter (p=0.04), 17% dilated portal vein (p=0.006), and 25% decreased portal vein blood flow velocity (p=0.001). Anti-viral therapy resulted in improvement of some hepatolienal blood flow parameters. Parameters of splanchnic circulation were correlated with cardiodynamic parameters with correlation coefficients from 0.51 to 0.95 at p.
