The relationship between high levels of anti-Varicella Zoster Virus (VZV) IgG in cerebrospinal fluid (CSF) and cerebrovascular atherosclerosis commends a possible similar association in other vessels. We aimed to investigate the association of VZV-seropositivity with coronary artery atherosclerosis. We recruited 88 newly diagnosed patients with more than 50% stenosis in at least one of the main coronary arteries. As the control group, 99 age-matched individuals with normal/insignificant coronary artery findings were included. Clinical, paraclinical, and demographical data were gathered at the time of sampling. High‐sensitivity C‐reactive protein (hsCRP) levels were measured by nephelometry. VZV-seropositivity was determined by measuring of anti-VZV IgG level in plasma. Multivariable logistic regression was used to evaluate the correlation of data with coronary vascular atherosclerosis. The frequency of VZV-seropositivity was significantly higher in the atherosclerosis group compared to the controls (OR=1.88; 95%CI=1.03-3.44). The plasma levels of anti-VZV IgG were significantly higher in patients with atherosclerosis (Median=2.70, IQR=1.53-4.30 AU/mL) than in the controls (Median=2.10, IQR=1.70-3.10 AU/mL, p=0.034). The hsCRP levels in patients and controls were 5.19±2.00 and 1.51±1.07 mg/L, respectively. The correlation between hsCRP and anti-VZV IgG level in plasma was observed (r=0.40, p<0.001). The levels of hsCRP and anti-VZV IgG increased based on the number of diseased vessels but only the difference in hsCRP levels reached a significant level (p<0.001 and p=0.168, respectively). Our data suggest that VZV-seropositivity and hsCRP elevation jointly increase the risk of atherosclerosis. The multifactorial nature of atherosclerosis; however, leaves more options for the inflammatory milieu to be generated.
