Treatment of Coronary Spastic Angina, Particularly Medically Refractory Coronary Spasm

Clinical Medicine Insights: Cardiology, 2008
Coronary spasm plays an important role in the pathogenesis of variant angina as well as ischaemic heart diseases. Treatment with vasodilators such as long-acting calcium channel blockers and long-acting nitrates is generally effective in preventing ...

Exercised-Induced Coronary Spasm in Near Normal Coronary Arteries

International Journal of Vascular Medicine, 2010
In contrast to effort-induced symptoms in obstructive coronary disease, spasm in normal coronary arteries is characterized by angina at rest. We describe a 44-year-old patient with minor coronary plaques and pure exercised-induced coronary spasm.

Mechanisms of Coronary Artery Spasm [PDF]

European Cardiology Review, 2023
Recent clinical trials have highlighted that percutaneous coronary intervention in patients with stable angina provides limited additional benefits on top of optimal medical therapy. This has led to much more attention being paid to coronary vasomotion abnormalities regardless of obstructive or non-obstructive arterial segments.

Complete atrio-ventricular block with coronary artery spasm due to direct laryngoscopy in a pediatric patient with laryngeal papillomatosis: a case report

JA Clinical Reports, 2021
Background Coronary artery spasm has rarely been reported in pediatric patients. Previous studies have reported comorbidities and risk factors for coronary artery spasms. We present the case of a complete atrio-ventricular (AV) block that occurred in the
