Abstract
BACKGROUND: Cirrhotic cardiomyopathy has been characterized by impaired contractile response to stress and/or altered diastolic relaxation, with electrophysiological abnormalities in the absence of known cardiac disease. However, the clinical significance of diastolic dysfunction (DDF) in cirrhotic patients has not been clarified. METHODS: We studied 84 cirrhotic patients with normal systolic function to evaluate the prevalence of DDF using tissue Doppler imaging, and to investigate the possible correlation of DDF with outcomes (hospitalization, death) and with the specific causes of death. RESULTS: The mean follow-up was 10±8months. DDF was diagnosed in 22 patients (26.2%). Patients with DDF more frequently had ascites (90.9% vs. 64.5 %; p=0.026), lower levels of albumin (OR: 5.39; p=0.004), higher NT-proBNP levels, and longer QTc interval (464±23ms vs. 452±30ms; p=0.039). At follow-up, patients with DDF did not have a higher incidence of adverse events in terms of hospitalization and death. CONCLUSIONS: The presence of diastolic dysfunction has not been found to be clearly associated with outcome, and prognosis has been determined primarily by the severity of liver disease.
