This is followed by a lifetime of latent infection with sporadic reactivations. Thus, this study was set to examine the relationship between latent CMV infection and outcomes following STEMI. In this investigation, blood samples from 354 STEMI patients who were enrolled in T-TIME (A Trial of Low-Dose Adjunctive Alteplase During Primary PCI) were cryopreserved. Overall, a slightly reduced LVEF in the first week and three months following STEMI is linked to latent CMV infection, which is frequent in patients with STEMI. Latent Cytomegalovirus infection is associated with impaired left ventricular function after ST-segment-elevation myocardial infarction.
