Key result
Cytomegalovirus immediate-early gene transcripts were detected in 50% of myocytes from HIV-infected patients with cardiomyopathy, compared to 0% in controls without cardiac disease.
Why the study?
Is cardiotropic cytomegalovirus (CMV) infection associated with the development of HIV-associated cardiomyopathy?
Case-Control (n=20)
No
Is cardiotropic cytomegalovirus (CMV) infection associated with the development of HIV-associated cardiomyopathy?
This study demonstrates the expression of the CMV immediate-early gene within myocytes of HIV-infected patients with cardiomyopathy, suggesting a role for non-permissive CMV infection in its pathogenesis.
Answers are grounded in this paper and cite their sources.
CMV gene expression in HIV cardiomyopathy myocytes warrants antiviral trials; leaves open causal confirmation and practice change.

Wu et al. (1992) conducted a case-control in HIV-associated cardiomyopathy (n=20). Cytomegalovirus (CMV) infection vs. HIV-infected patients without cardiac disease was evaluated on Specific myocyte nuclear and perinuclear hybridization for transcripts of the CMV immediate-early (IE) gene. Cytomegalovirus immediate-early gene transcripts were detected in 50% of myocytes from HIV-infected patients with cardiomyopathy, compared to 0% in controls without cardiac disease.
