Angiography conducted in 29 anginal patients has shown that coronary arteries were intact in 23 and little affected in 6 of them. Signs of myocardial ischemia were recorded at myocardial scintigraphy, bicycle ergometry, 24-h ECG monitoring in 17 patients. Esophageal lesions confirmed by endoscopy, manometry, esophageal pH-metry with Bernstein test were revealed in 20 examinees (68%). It is suggested that patients with persistent chest pain and unaffected coronary arteries who are resistant to antianginal therapy should undergo functional study of the esophagus including endoscopy, manometry and pH-metry.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

Background: Coronary Artery Spasm (CAS) often presents in the epicardial coronary arteries. The anterior septal branch is distributed within the myocardium, and occurrences of spasms are rare. Currently, there is no available literature on this topic, and the onset of symptoms remains elusive, potentially leading to misdiagnosis.

We compared chorioretinal microvascular of Slow Coronary Flow Phenomenon (SCFP) patients using Optical Coherence Tomography Angiography (OCTA) to healthy controls. We recruited 21 patients from September 2023 until January 2024 from two referral centers. We enrolled 21 age-sex-matched controls retrospectively.

Coronary artery vasospasm (CAV) is characterized by transient constriction of epicardial coronary arteries leading to angina. Its disease mechanisms are multifactorial but has centered mostly on endothelial dysfunction and smooth muscle hyperreactivity. To facilitate the investigation of these mechanisms in cell culture, we generated and characterized three induced pluripotent stem cell (iPSC) lines from patients with CAV.

Computed tomography coronary angiography (CTCA) is under-utilised in detecting coronary artery disease (CAD) in obese patients due to concerns about non-evaluable testing. We hypothesise that these concerns are predominantly related to smaller and branch coronary vessels, and CTCA remains adequate for proximal segment stenosis interpretation, which has significant clinical implications. This retrospective cohort study, on consecutive patients referred for CTCA for suspected CAD, grouped patients by body mass index.
