Are the high levels of cytomegalovirus antibodies a determinant in the development of coronary artery disease?

In several epidemiological studies, it was suggested that a high titer of cytomegalo-virus (CMV) antibody meant CMV reactivation, and that this condition was a determinant of coronary artery disease (CAD). The purpose of this study was to investigate both the prevalence of the CMV infections in our study population and whether high CMV sero-positivity is a determinant of CAD. Blood samples from 179 (58 female, 121 male) individuals being evaluated for CAD suspicion by coronary angiography were tested for CMV seropositivity and CRP levels. Fifty-six patients had normal coronary arteries and 123 patients had CAD. Six patients did not have anti-CMV antibodies and 87 of the 173 seropositive patients had high levels of anti-CMV antibodies (> or = 8 U/mL). High CMV seropositivity (> or = 8 U/mL) was a significant CAD determinant even after adjustment for traditional CAD risk factors (odds ratio [OR] = 2.1 P = 0.04, respectively). The results indicate that the prevalence of high CMV seropositivity is an independent predictor of CAD in our study population and that our study population with CAD had a high rate of CMV infection.
