Comparison of epicardial coronary artery tone and reactivity in Prinzmetal's variant angina and chronic stable angina pectoris [PDF]
It has been suggested that a generalized coronary vasomotion disorder is present in variant angina and that evaluation of baseline coronary artery tone may be useful for predicting the occurrence of coronary artery spasm.

ABSTRACT Background In patients with acute coronary syndrome (ACS) and multivessel disease (MVD), complete revascularization (CR) improves clinical outcomes compared with culprit‐only percutaneous coronary intervention (PCI). However, the optimal timing of CR, immediate (ICR) versus staged (SCR), remains debated.

Introduction: The syndrome of variant angina occurs in patients with awide spectrum of coronary artery obstructions, ranging from normal coronary arteries to severe 3-vessel coronary arterydisease (CAD). Treatment of these patients is, in large part, determined by the extent and severity of the underlyingfixed coronary obstructions.

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

Vasospasm or Atherosclerotic Lesion of Coronary Arteries: Case Management
Background. Coronary artery vasospasm (CVS) is an important mechanism of myocardial ischemia which can produce any of the manifestations of coronary artery disease from silent myocardial ischemia to acute coronary syndrome including myocardial infarction

ABSTRACT Background There are limited data evaluating the association between operator−patient sex, and outcomes in patients undergoing percutaneous coronary intervention (PCI). Methods We included 138,112 consecutive PCI procedures in patients presenting with acute coronary syndrome (ACS) in England and Wales, 2017−2020.

ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

ABSTRACT Background Despite recommendations in international guidelines, Intracoronary pressure wire assessment (PWA) utilization remains limited in clinical practice. This study aims to describe (i) trends of PWA during Percutaneous coronary interventional (PCI), (ii) factors that predict its application, and (iii) association with in‐hospital ...
