Coronary Microvascular Dysfunction: Epidemiology, Pathophysiology, Diagnosis, and Treatment

MedComm, Volume 7, Issue 8, August 2026.
This visual summary illustrates the key aspects of coronary microvascular dysfunction (CMD) in angina with nonobstructive coronary artery disease (NOCAD), including epidemiology, pathophysiology (microvascular remodeling and endothelial dysfunction), the protective NRG‐1/ErbB signaling pathway, diagnostic methods, and both Western and traditional ...

A modality‐agnostic coronary artery habitat model for cardiac sparing in radiotherapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Emerging evidence suggests that the risk of cardiotoxicity increases with increased radiation dose to coronary arteries (CAs). However, robust tools to evaluate this increased burden for cancer patients are not available due to current limitations in imaging for radiotherapy treatment planning.

Experimental quantification of frame‐level active window duration and duty cycle in high frame rate x‐ray detectors

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Detector frame rate is commonly used as the primary metric to characterize the temporal behavior of x‐ray detectors in medical imaging systems. However, frame rate alone specifies only the sampling rate of image frames and does not determine how x‐ray interaction signals are temporally integrated to form the measured signal within ...

Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

VIEW Medicine, Volume 1, Issue 1, August 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

Evaluating high‐sensitivity troponin levels in people with sickle cell disease in the emergency department

British Journal of Haematology, Volume 209, Issue 2, Page 833-836, August 2026.
This study shows that sickle cell disease patients have elevated high‐sensitivity cardiac troponin I (hs‐cTnI) that is not considered clinically significant but are outside of the normal range. Elevated hs‐cTnI was associated with low haemoglobin and a history of heart failure.
