Abstract

Human cytomegalovirus (HCMV) infection is an important risk factor for atherosclerosis (AS). Numerous studies have been conducted to analyze the association between HCMV infection and risk of AS, but no clear consensus has been reached. So the objective of this paper was aimed to demonstrate the relationship between HCMV and AS by doing a meta-analysis. Relative literature was searched through the electronic databases PubMed, Embase, and CNKI. Data were accurately assessed and analyzed independently by two investigators. Ultimately, the 30 studies, involving 3328 cases and 2090 controls were included in our meta-analysis. The positive ratio of HCMV IgG, IgM, DNA and pp65 were, respectively, 63.26% (923/1459), 25.46% (69/271), 33.69% (381/1131), and 50.32% (158/314) in case patients. Meanwhile the positive ratio of HCMV IgG, IgM, DNA, and pp65 were, respectively, 52.12% (541/1038), 1.55% (3/194), 13.72% (79/576), and 12.26% (28/229) in control subjects. The positive ratio of HCMV infection was higher in atherosclerosis group than that in non-atherosclerosis group. Especially in Asian group, calculated odds ratios for the presence of HCMV infection in IgG-based HCMV tests, IgM-based tests, PCR-based tests, and pp65-based tests, expressed as OR (95% confidence intervals, 95%CI), were 3.07(95%CI 2.09-4.51), 8.92(95%CI 3.17-25.11), 6.75 (95%CI 3.50-13.02), and 5.72(95%CI 1.51-21.58), respectively. The meta-analysis results showed that HCMV infection is significant connected with an increased risk for AS.
