Abstract:

Oxidative stress due to an excess of reactive oxygen species (ROS) may play a role in the development and progression of cardiovascular disease (CVD). 8-hydroxy-2'-deoxyguanosine (8-OHdG) is a marker of oxidative DNA damage caused by ROS. This review aimed to assess the association between 8-OHdG and CVD by reviewing the literature. Studies in human subjects using either plasma or urine to determine 8-OHdG concentrations were surveyed. Eighteen relevant studies were found, of which 13 were case-control studies and five had a prospective design. Without exception, the case-control studies showed significant positive associations between 8-OHdG and CVD. In agreement, two prospective studies showed a significant association of 8-OHdG and heart failure. Furthermore, two prospective studies found a significant association between 8-OHdG and stroke, and finally, one prospective study showed a borderline significant (p = 0.08) association between coronary artery disease (CAD) patients developing a cardiac event and 8-OHdG concentrations. In conclusion, high levels of 8-OHdG in blood and urine are associated with atherosclerosis and heart failure, but further large prospective studies are needed to investigate 8-OHdG as a predictor for cardiovascular diseases.
