Insights
Hepatitis B virus infection showed no significant association with coronary artery disease (CAD) risk in this Iranian patient cohort. Further research is needed to confirm these findings regarding viral infections and atherosclerosis.
Area of Science:
- Cardiology
- Infectious Diseases
- Epidemiology
Background:
- Coronary artery disease (CAD) has been linked to persistent infections.
- The relationship between hepatitis B virus (HBV) infection and atherosclerosis risk remains unclear.
Purpose of the Study:
- To investigate the potential association between hepatitis B virus infection and the risk of developing coronary artery disease.
Main Methods:
- Enzyme-linked immunosorbent assay (ELISA) was used to detect hepatitis B surface antigen (HBsAg) in 5,004 patients undergoing coronary angiography.
- Sera were collected from patients at Madani Heart Hospital, Tabriz University of Medical Sciences, Iran.
Main Results:
- The study included 66% males and 34% females, aged 36-86 years.
- Hepatitis B surface antigen (HBsAg) positivity was slightly higher in patients with CAD (3.28%) compared to those without (2.17%), but this difference was not statistically significant.
Conclusions:
- Hepatitis B virus infection does not appear to be associated with coronary atherosclerosis in the studied population.
- The findings suggest that HBV may not be a significant risk factor for developing coronary atherosclerosis.
Introduction:
Many studies have reported on the association between human coronary artery disease (CAD) and certain persistent bacterial and viral infections. Currently, it is unclear whether hepatitis B virus infection is associated with the risk of the atherosclerosis. The aim of this study was to investigate the possible association between hepatitis B virus infection and angiography-proven CAD.
Materials And Methods:
Sera from 5,004 patients who underwent coronary angiography were tested for hepatitis B surface antigen (HBsAg) by enzyme-linked immunosorbant assay at Madani Heart Hospital, Tabriz University of Medical Sciences, Iran.
Results:
Our study population comprised 66% male and 34% female, with an age range of 36 to 86 years. The prevalence of HBsAg positivity tended to be higher in CAD patients than in those without CAD (3.28% versus 2.17%), but the difference was not statistically significant.
Conclusion:
Our results suggest that hepatitis B virus infection is not associated with coronary atherosclerosis in this population.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
