Autonomic and diastolic dysfunction association with quality of life impairment in cirrhotic patients

Abstract

Background and study aims: Cirrhosis is a multisystem disorder characterized by hyperdynamic circulation which can progress to multiple organ dysfunctions. Recent studies have demonstrated autonomic dysfunction and cirrhotic cardiomyopathy including diastolic dysfunction, systolic dysfunction with electrophysiologic abnormalities in patients with cirrhosis. Due to the long and complicated course of the disease, health related quality of life is affected. We aimed to evaluate the frequency of diastolic dysfunction and autonomic dysfunction in cirrhosis, and the effects on health-related quality of life.

Patients and methods: Hundred cirrhotic patients were enrolled in the study. According to the Child-Pugh classification 35 patients were of Child A, 36 of Child B and 29 of Child C. The proportion of autonomic dysfunction was 52%, and diastolic dysfunction 51%. Autonomic dysfunction was diagnosed using bedside maneuvers and tests; diastolic dysfunction was diagnosed using the E/A ratio in echocardiographic findings. Health-related quality of life measurements was obtained from an SF-36 questionnaire.

Results: Patients with advanced Child-Pugh classifications were found to have significantly lower health-related quality of life values (p < 0.05). Likewise, health-related quality of life values were observed to be significantly lower in patients with autonomic dysfunction (p < 0.05). No significant difference was found in health related quality of life measurements between patients with and without diastolic dysfunction.

Conclusion: Our study showed that autonomic dysfunction and diastolic dysfunction are found in patients with cirrhosis. Further studies are needed to assess the effects of autonomic dysfunction and diastolic dysfunction on health-related quality of life.
