Clinical Outcomes and Provoked Epicardial Spasm Phenotypes via Intracoronary Acetylcholine Testing in 680 Patients with Angina and Nonobstructive Coronary Arteries

Life, 2022
Background: Epicardial spasm (ES) phenotypes may be related to the prognosis in patients with coronary spastic angina. Objectives: The purpose of this study was to elucidate the relationship between angiographic coronary vasomotor responses to ...

A Case of Spontaneous Multivessel Coronary Artery Spasm That Underwent Stent Implantation Accompanying ST Segment Elevation on Inferior Electrocardiographic Leads

Case Reports in Cardiology, 2016

Nitroglycerin to Ameliorate Coronary Artery Spasm During Focal Pulsed-Field Ablation for Atrial Fibrillation.

JACC Clinical Electrophysiology
BACKGROUND In treating atrial fibrillation, pulsed-field ablation (PFA) has comparable efficacy to conventional thermal ablation, but with important safety advantages: no esophageal injury or pulmonary vein stenosis, and rare phrenic nerve injury ...

Coronary Artery Spasm, Coronary Reactivity and Their Psychological Context

Psychosomatic Medicine, 2019
Symptomatic individuals suspected of having myocardial ischemia often have no obstructive atherosclerotic narrowing of epicardial coronary arteries. Abnormal coronary vascular reactivity, and in particular, coronary artery vasospasm (CAS), may be an ...

A rare case of spontaneous and simultaneous multivessel coronary artery spasm leading to multisite myocardial infarction and ventricular fibrillation

ARYA Atherosclerosis, 2018
BACKGROUND: Coronary artery spasm (CAS) can result in life-threatening arrhythmia and sudden cardiac death. Although this disorder has been known for a long time, little is known about it, and its mechanisms have been not identified yet.CASE REPORT: We ...
