Variability of heart rhythm in patients with viral cirrhosis depending on types of portal blood flow

Abstract

The paper analyzes the results of examinations of 24 patients with viral cirrhosis of classes B and C according to Child-Pugh criteria. The control group consisted of 16 healthy patients. Patients with viral cirrhosis were divided into 2 groups: 1 group consisted of 14 patients with pseudonormokinetic type of portal blood flow; Group 2-10 patients with hyperkinetic type of portal blood flow with predominant acceleration of the linear velocity in the portal vein. The average age of patients was 35.2 ± 7.4 years. Left ventricular myocardium mass and left ventricular myocardium mass index were determined in all the patients; the diameter and the maximum linear velocity in the main portal vein were measured using an Artida pro Toshiba apparatus, Japan. Heart rate variability was studied at rest and in active orfhostasis using the «Neuro-Soth)program, Ivanovo. it was found that in patients with liver cirrhosis the sympathetic effects of the autonomic nervous system predominated, which coincided with the literature data. It was also shown that in patients with the pseudonormokinetic type of portal blood flow these effects were more pronounced. The relationship between HRV indices and the formation of left ventricular hypertrophy in patients with pseudo-normokinetic type of portal blood flow was revealed.
