Catheter-induced spasm of the left main coronary artery.

, 2000
Catheter-induced spasm of the left main coronary artery is rare during catheterization. We present several cases in which the occurrence of both ostial left main and right coronary spasm suggests that multiple sites of spasm may be a clue to this ...

Severe multivessel coronary artery spasm presenting as very high-risk acute coronary syndrome

Coronary artery spasm is an important cause of myocardial ischaemia and acute coronary syndrome in the absence of obstructive coronary artery disease. Simultaneous multivessel epicardial coronary artery spasm is an uncommon presentation and may closely ...

Frequency of provoked coronary arterial spasm in 1089 consecutive patients undergoing coronary arteriography.

, 1982
We established the incidence of coronary artery spasm provoked by 0.4 mg of methergine in 1089 consecutive patients undergoing coronary angiography. The test was performed after routine coronary arteriography. Subjects included patients with angina, both

Induction of coronary artery spasm by acetylcholine in patients with variant angina: possible role of the parasympathetic nervous system in the pathogenesis of coronary artery spasm.

, 1986
We injected acetylcholine (ACh), the neurotransmitter of the parasympathetic nervous system, into the coronary arteries of 28 patients with variant angina.

Case Report: Left main coronary artery spasm in monozygotic twins patients with vasospastic angina

Frontiers in Cardiovascular Medicine
Coronary artery spasm (CAS), a known cause of myocardial ischemia that can present as variant angina, is primarily triggered by intraoperative catheter manipulation. Evidence for a genetic predisposition to coronary artery spasm is scarce.

A Review of the Role of Tests of Coronary Reactivity in Clinical Practice

European Cardiology Review
Vasoreactivity testing is used by cardiologists in the diagnosis of coronary spasm endotypes, such as epicardial and microvascular spasm. Intracoronary injection of acetylcholine and ergonovine is defined as a standard class I method according to the ...

Coronary artery spasm as a cause of ST elevation and inappropriate implantable cardioverter defibrillator intervention

, 2007
Coronary artery spasm can cause both brady- and tachyarrhythmia, through induction of AV block (usually linked to coronary spasm of the right coronary artery) or ventricular tachycardia/fibrillation linked to extensive myocardial ischemia.
