Key result
Gated SPECT rules out CAD in HIV cardiomyopathy, sparing unnecessary invasive angiography.
Why the study?
Multimodal imaging is needed to establish correct diagnosis and avoid unjustified invasive methods in HIV patients with secondary cardiomyopathy due to combined HIV and oncologic pathology.
Case Report (n=1)
Multimodal imaging with ECG-gated SPECT successfully differentiated secondary non-ischemic cardiomyopathy from ischemic heart disease in a complex patient with HIV and lymphoma, optimizing medical management and avoiding unnecessary invasive procedures.
May support ECG-gated SPECT to avoid angiography in select HIV cardiomyopathy cases; leaves open need for prospective validation.
The article presents a clinical case of secondary cardiomyopathy in an HIV patient with plasmablastic lymphoma due to the combined pathology (HIV infection with ongoing antiretroviral therapy in combination with antitumor therapy), in which the use of multimodal imaging contributed to establishing the correct diagnosis and excluding the unjustified use of invasive methods for diagnosing ischemic heart disease.

Chanakhchian et al. (2024) conducted a case report in Secondary cardiomyopathy in HIV and lymphoma (n=1). ECG-gated SPECT myocardial perfusion imaging was evaluated on Differential diagnosis between ischemic heart disease and non-ischemic cardiomyopathy. ECG-gated SPECT myocardial perfusion imaging confirmed non-ischemic cardiomyopathy and ruled out coronary artery disease in a 48-year-old HIV patient, preventing unnecessary invasive angiography.
