Interestingly, as we and others have shown, latent cytomegalovirus (CMV) infection is also associated with clonal expansion of CD8+ memory T cells [88], myocardial T cell infiltration, and ventricular remodelling after MI [89]; whether CMV seropositivity contributes to subclinical myocardial inflammation in HF patients is unknown. Here, CD8A is linked to myocardial infarction.
