Insights
Hepatitis C virus (HCV) infection may impact heart function, potentially causing left ventricular systolic and diastolic dysfunction. This study investigated cardiac function in HCV patients, revealing significant differences compared to healthy individuals.
Area of Science:
- Cardiology
- Infectious Diseases
- Hepatology
Background:
- Hepatitis C virus (HCV) infection is a global health concern.
- HCV is linked to various extrahepatic manifestations.
- Cardiac involvement, specifically cardiomyopathy, has been noted in HCV patients, but effects on ventricular function were unclear.
Purpose of the Study:
- To assess left ventricular systolic and diastolic functions in patients with Hepatitis C virus infection.
- To identify potential cardiac dysfunction associated with HCV.
Main Methods:
- Transthoracic echocardiography and P-wave analysis were performed on 50 anti-HCV positive patients and 50 controls.
- Left ventricle diastolic parameters, ejection fraction, and P-wave dispersion (Pd) were compared between groups.
Main Results:
- HCV patients showed a lower E/A ratio (1.2 vs. 1.37) and a higher E/Em ratio (7.6 vs. 6.8), indicating diastolic dysfunction.
- Maximum P-wave duration (Pmax) and P-wave dispersion (Pd) were significantly higher in HCV patients (99.3 ms vs. 82.4 ms and 44.1 ms vs. 25.3 ms, respectively).
- No significant differences were found in left ventricle systolic parameters, including ejection fraction.
Conclusions:
- Hepatitis C virus infection is associated with impaired left ventricular diastolic function.
- HCV may contribute to the development of cardiac arrhythmias.
Background:
Hepatitis secondary to infection with the hepatitis C virus (HCV) is one of the most common causes of viral hepatitis worldwide. Multiple extrahepatic manifestations of HCV infection have been recognized. Dilated and hypertrophic cardiomyopathy associated with HCV infection have been recently described in the literature; however, the effect of HCV infection on the left ventricular systolic and diastolic functions is unknown. Therefore, in this study we aimed to examine left ventricular systolic and diastolic functions in HCV patients.
Methods And Results:
The study included 50 anti-HCV positive patients and 50 persons for control groups. We performed transthorasic echocardiography and P-wave analysis on all participants. We compared left ventricle diastolic parameters, left ventricle ejection fraction, and P-wave dispersion (Pd) between these two groups. In the group with anti-HCV positivity, the ratio of E/A was found to be lower (1.2 ± 0.7 and 1.37 ± 0.6, P = 0.003); the ratio of E/Em was found to be higher (7.6 ± 1.51 and 6.8 ± 1.72, P = 0.0001). Maximum P-wave duration (Pmax) and Pd were higher in the patient group (99.3 ± 8 and 82.4 ± 7.8, P = 0.004; 44.1 ± 0.9 and 25.3 ± 1.5, P = 0.001). No other statistically significant difference was found between the two groups with regard to the left ventricle systolic and diastolic parameters.
Conclusion:
Our findings show that HCV infection may be associated with left ventricular systolic and diastolic dysfunction and cardiac arrhythmias.
