Ethereum's public mempool exposes every pending transaction to adversaries who can reorder, insert, or censor transactions for profit — a phenomenon known as Maximal Extractable Value (MEV), and the reason practitioners describe the mempool as a "dark forest." While a substantial measurement …

BACKGROUND AND AIMS: Invasive coronary function testing (CFT) identifies coronary vasomotor disorders in up to 90% of patients with angina with non-obstructive coronary arteries (ANOCA). The ILIAS ANOCA trial hypothesized that routine ad hoc CFT would be feasible, safe, and effective in …

Background: Coronary functional disorders (CFD) are significant contributors to angina with non-obstructed coronary arteries (ANOCA). Various endotypes, such as epicardial or microvascular spasm and/or coronary microvascular dysfunction (CMD), have been identified. Previous studies have shown a high prevalence of CFD in ANOCA …

Abstract Background Approximately 5–15% of patients with acute coronary syndrome have myocardial infarction with unobstructed coronary arteries (MINOCA). Guidelines recommend invasive assessments to identify underlying causes for MINOCA such as coronary artery spasm (CAS), spontaneous coronary dissection, or microvascular disease as well …

Coronary spasm (CS), which may occur at the epicardial (focal or diffuse spasm) and/or microvascular (microvascular spasm) level, is a well-established cause of myocardial ischaemia, in particular in patients with anginal chest pain despite unobstructed coronary arteries. The diagnosis of CS can …
