Abstract
Objectives
Non-alcoholic fatty liver disease (NAFLD) is a multisystem disease which can affect the cardiovascular system as well. We conducted this study to determine the cardiac effects of NAFLD such as conduction of impulse and ventricular repolarisation on electrocardiography (ECG).
Methods
In this study, we recruited patients with risk factors for NAFLD (group I; n = 23) and NAFLD patients (group II; n = 74) from Shar Hospital in Sulaimani City, Iraq. We analysed anthropometric measurements, serum fasting lipid profile, glucose levels, liver enzymes, and ECG recordings.
Results
ECG recordings showed significantly longer PR intervals, significantly shorter QTcB and JTc intervals, and a higher Tp-e/QTcB ratio in group II patients than in group I patients. These abnormalities were not associated with risk factors for diabetes. The TQ duration was significantly correlated with serum alanine aminotransferase (r = 0.411, p < 0.001) and aspartate aminotransferase (r = 0.272, p = 0.019) levels.
Conclusion
In our study, the presence of significant abnormalities in ventricular repolarisation suggests that patients with newly diagnosed NAFLD have subclinical cardiac stress and a higher risk of ventricular arrhythmias.
Non-alcoholic fatty liver disease patients are at risk of developing ventricular repolarization.
Abnormal electrocardiograph changes are related to the serum levels of liver enzymes.
People at risk of developing non-alcoholic liver disease are also have abnormal ventricular repolarization indices.
