Background: Angina with non-obstructive coronary artery disease (ANOCA) is commonly observed in patients with stable angina undergoing coronary angiography. Current guidelines recommend non-invasive stress testing as the first step in diagnosing coronary microvascular disease (CMD). This study aims to evaluate the diagnostic value of non-invasive stress testing in patients invasively diagnosed with CMD.

The eye and the heart are two closely interlinked organs, and many diseases affecting the cardiovascular system manifest in the eye. To contribute to the understanding of blood flow propagation towards the retina, we developed a method to acquire electrocardiogram (ECG) coupled time-resolved dynamic optical coherence tomography (OCT) images. This method allows for continuous synchronised monitoring of the cardiac cycle and retinal blood flow dynamics.

Cardiac MRI (CMR) is an important imaging modality in the evaluation of cardiovascular diseases. CMR image acquisition is technically challenging, which in some circumstances is associated with artifacts, both general as well as sequence specific. Recognizing imaging artifacts, understanding their causes, and applying effective approaches for artifact mitigation are critical for successful CMR.

Shih-Hua Lin is a professor, Division of Nephrology, Department of Medicine, Tri-Service General Hospital, National Defense Medical Center, Taipei.
Background: Hyperkalemia can be detected by point-of-care (POC) blood testing and by artificial intelligence- enabled electrocardiography (ECG). These 2 methods of detecting hyperkalemia have not been compared.
Objective: To determine the accuracy of POC and ECG potassium measurements for hyperkalemia detection in patients with critical illness.
Chest Pain at Rest With Unremarkable ECG and Cardiac Enzymes: Case Study Emphasising the Importance of Clinical Suspicion in the Diagnosis of Coronary Artery Disease.

December 2024
Department of Health and Care Professions, Faculty of Health and Life Sciences, University of Exeter, Exeter, U.K.;
Background: Coronary artery disease (CAD), primarily caused by atherosclerosis, is a leading cause of death, presenting as angina or myocardial infarction. Advances in cardiac imaging, angiography, and procedures like percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery have improved early detection and management of this condition. This report presents the case of a man who experienced worsening exertional chest pain and discomfort while at rest.
