The Role of Intersectional Stigma in Coronary Artery Disease Among Cisgender Women Aging with HIV.

Cisgender women living with HIV experience elevated cardiovascular disease (CVD) risk that increases with age, a concern given extended life expectancies for people living with HIV. The CVD risk disparity among cisgender women aging with HIV is understudied and remains unclear. Taking a psychoneuroimmunology approach, given this group's intersecting marginalized identities, one potential driver of the disparity is intersectional stigma.

Dose Comparison Study of Allogeneic Mesenchymal Stem Cells in Patients With Ischemic Cardiomyopathy (The TRIDENT Study).

Rationale: Cell dose and concentration play crucial roles in phenotypic responses to cell-based therapy for heart failure.

Objective: To compare the safety and efficacy of 2 doses of allogeneic bone marrow-derived human mesenchymal stem cells identically delivered in patients with ischemic cardiomyopathy.

Methods And Results: Thirty patients with ischemic cardiomyopathy received in a blinded manner either 20 million (n=15) or 100 million (n=15) allogeneic human mesenchymal stem cells via transendocardial injection (0.

Randomized Comparison of Allogeneic Versus Autologous Mesenchymal Stem Cells for Nonischemic Dilated Cardiomyopathy: POSEIDON-DCM Trial.

Background: Although human mesenchymal stem cells (hMSCs) have been tested in ischemic cardiomyopathy, few studies exist in chronic nonischemic dilated cardiomyopathy (NIDCM).

Objectives: The authors conducted a randomized comparison of safety and efficacy of autologous (auto) versus allogeneic (allo) bone marrow-derived hMSCs in NIDCM.

Methods: Thirty-seven patients were randomized to either allo- or auto-hMSCs in a 1:1 ratio.

Assessment of Diastolic Function in Hypertrophic Cardiomyopathy by Computed Tomography-Derived Analysis of Left Ventricular Filling.

Objectives: Hypertrophic cardiomyopathy (HCM) is characterized by diastolic dysfunction, which is difficult to assess by noninvasive methods. We hypothesized that measurement of simultaneous left ventricular (LV) and left atrial (LA) volume changes by cardiac computed tomography would be useful in the assessment of diastolic function in HCM.

Methods: We studied 21 patients with HCM and 21 age-matched controls.

Cardiac Physiology for Radiologists: Review of Relevant Physiology for Interpretation of Cardiac MR Imaging and CT.

Cardiac computed tomography (CT) and magnetic resonance (MR) imaging provide clinicians with important insights into cardiac physiology and pathology. However, not all radiologists understand the language and concepts of cardiac physiology that are used daily by cardiologists. This review article covers basic cardiac physiology as it relates to cardiac CT and MR imaging.
