Adapting Novel Augmented Reality Devices for Patient Simulations in Medical Education.

Extended reality (XR) simulations are becoming increasingly common in educational settings, particularly in medical education. Advancing XR devices to enhance these simulations is a booming field of research. This study seeks to understand the value of a novel, non-wearable mixed reality (MR) display during interactions with a simulated holographic patient, specifically in taking a medical history.

Prognostic utility of cardiovascular magnetic resonance upright maximal treadmill exercise testing.

Background: Left ventricular wall motion abnormalities (LVWMA) observed during cardiovascular magnetic resonance (CMR) pharmacologic stress testing can be used to determine cardiac prognosis, but currently, information regarding the prognostic utility of upright maximal treadmill induced LVWMA is unknown. Our objective was to determine the prognostic utility of upright maximal treadmill exercise stress CMR.

Methods: One hundred and fifteen (115) men and women with known or suspected coronary arteriosclerosis and an appropriate indication for cardiovascular (CV) imaging to supplement ST segment stress testing underwent an upright treadmill exercise CMR stress test in which LVWMA were identified before and immediately after exercise.

Intra-coronary bone marrow mononuclear cell transplantation in patients with ST-elevation myocardial infarction: a randomized controlled study.

Background: Stem cell transplantation is a potential treatment to improve left ventricular ejection fraction (LVEF) after ST elevation myocardial infarction (STEMI). However, the outcomes still are controversial.

Objective: To determine the 6-month LVEF of the patients who underwent intra-coronary bone marrow mononuclear cell (BMC) transplantation in patients with STEMI compared with controlled subjects.

Transcoronary infusion of bone marrow derived multipotent stem cells to preserve left ventricular geometry and function after myocardial infarction.

Background: Myocardial damage after myocardial infarction (MI) was deemed irreversible after late reperfusion. Administration of multipotent stem cell (MSC) into such infarct may regenerate the myocardium and capillary network.

Hypothesis: Transcoronary infusion of bone marrow derived multipotent stem cells into infarcted related artery after acute myocardial infarction is feasible, safe and improve left ventricular function.
