Radial artery spasms - angiographic morphology, risk factors and management.
Postepy Kardiol Interwencyjnej
March 2024
Article Synopsis
- Radial artery access is often preferred in coronary interventions, but spasms can occur, causing pain and complications during the procedure.
- In a study of 103 patients, the incidence of radial artery spasm was found to be 24.3%, with factors like female sex and failed puncture attempts increasing the risk, while hydrophilic sheaths seemed to prevent spasms.
- Signs of arterial spasm were frequently observed in angiographies but did not always result in significant symptoms; tight narrowing at the sheath tip was a notable predictor of symptomatic spasm.

Article Synopsis
- Each week, the Editor-in-Chief conducts a thorough review of articles before they are published online, evaluating their significance, originality, and peer reviewer ratings.
- Based on this assessment, selected papers are chosen for publication, along with proposed changes, particularly in titles, to enhance clarity and relevance.
- This meticulous process, though time-consuming, ensures high-quality publications and draws attention to important articles for readers.
The coronavirus disease 2019 (COVID-19) infected so far over 250 million people and caused the death of over 5 million worldwide. Aging, diabetes, and cardiovascular diseases, conditions with preexisting impaired endothelial functions predispose to COVID-19. While respiratory epithelium is the main route of virus entry, the endothelial cells (ECs) lining pulmonary blood vessels are also an integral part of lung injury in COVID-19 patients.

Tissue injury healing is impaired in aging, and this impairment is caused in part by reduced angiogenesis. Melatonin, a neuroendocrine hormone that regulates sleep and circadian rhythm, is also produced in the gastrointestinal tract. The expression of melatonin receptors MT1 and MT2 in gastric endothelial cells and their roles in aging-related impairment of gastric angiogenesis have not been examined.

A gastric ulcer (GU) is a deep defect in the gastric wall penetrating through the entire mucosa and the muscularis mucosae. GU healing is a regeneration process that encompasses cell dedifferentiation, proliferation, migration, re-epithelialization, formation of granulation tissue, angiogenesis, vasculogenesis, interactions between various cells and the matrix, and tissue remodeling, all resulting in scar formation.
