Seroprevalence of cytomegalovirus in patients with and without coronary artery diseases at Madani Heart Center, Iran.

Inflammation plays a major role in coronary artery disease (CAD). Currently, it is unclear, whether Cytomegalovirus (CMV) infection is associated with the risk of the atherosclerosis. The aim of this study was to determine the prevalence of anti- CMV antibodies in CAD and non CAD patients undergoing artery bypass surgery. Sera from 157 patients who underwent coronary angiography were tested for CMV by enzyme linked immunosorbent assay (ELISA) at Madani Heart Hospital, Tabriz University of Medical Sciences, Iran. Our study population was 58.6% male and 41.4% female, with an age range of 38 to 86 years. The prevalence of CMV positivity tended to be higher in coronary artery diseases patients than in those without non coronary artery diseases (83.2% versus 63.6%) (P= 0.01). This analysis demonstrated that CMV seropositivity may be a risk factor for CAD in the present study population.
