The Mystery of Coronary Artery Spasm
Heart, Lung and Circulation, 2007Coronary artery spasm is an important cause of chest pain and myocardial ischaemia. It can be defined as an exaggerated contractile response of epicardial coronary artery smooth muscle to various stimuli but the underlying mechanism is not well understood.

Spasm in Ectatic Coronary Arteries
Mayo Clinic Proceedings, 1985Patients with ectatic coronary arteries often have occlusion of the affected arteries. Because ectatic arteries are considered to have medial damage, they are normally assumed to have little capacity to constrict; therefore, spasm has not been considered a factor in the occlusive process. In two patients who had diffuse coronary ectasia, no appreciable

Coronary artery spasm in hypothyroidism
The American Journal of Cardiology, 1985Abstract A previous report by Wei et al 1 documented coronary spasm possibly caused by hyperthyroidism. It was speculated that an increase in the number of α receptors secondary to hyperthyroidism may render the coronary arteries more vulnerable to spasm when transient increases in parasympathetic tone with attendant post-ganglionic catecholamine ...

Multivessel Coronary Artery Spasm
Heart, Lung and Circulation, 2012Coronary spasm is increasingly recognised as an important aetiological mechanism causing myocardial ischaemia. Occasionally cases present with evidence of ST segment elevation myocardial infarction, usually secondary to spasm confined to a solitary coronary artery.

Single coronary artery with spasm
Radiation Medicine, 2008A single coronary artery is a rare and potentially serious anomaly. We present the case of a 54-year-old woman with chest pain predominantly at rest. A single coronary artery was demonstrated by 64-row multidetector computed tomography (CT) imaging, which is useful for the diagnosis and classification of coronary anomaly.

Chest, 1984
Coronary artery spasm was virtually unknown not long ago, but the intense, ongoing interest it has generated in the past decade has produced a number of specific diagnostic techniques and therapeutic approaches, as well as considerable insight into mechanisms of coronary vascular tone and various coronary syndromes.

Coronary Artery Spasm Following Coronary Artery Surgery
The Annals of Thoracic Surgery, 1988Coronary artery spasm during the early postoperative period following cardiopulmonary bypass for coronary artery surgery can be an unrecognized cause of sudden, severe cardiopulmonary collapse. The literature regarding perioperative coronary artery spasm is reviewed, and methods of prevention, diagnosis, and treatment are suggested. Preoperative angina

Coronary Artery Spasm Following Coronary Artery Revascularization
The Annals of Thoracic Surgery, 1982Coronary artery spasm is a well-documented phenomenon in patients undergoing medial treatment. We describe coronary artery spasm occurring in the immediate postoperative period following coronary artery bypass operation. The spasm occurred in a vessel that was not operated on and that had no apparent lesion.

Mechanisms of coronary artery spasm
Trends in Cardiovascular Medicine, 1991Coronary artery spasm, the pathogenic mechanism most frequently observed in the syndrome of Prinzmetal's variant angina, appears to be caused by a local, nonspecific smooth muscle hyperreactivity. The relationship between coronary atherosclerosis, endothelial dysfunction, and coronary artery spasm is still speculative.

The electrocardiogram and coronary artery spasm
International Journal of Cardiology, 1984This discussion does not attempt to explain why the ECG of patients during rest angina accompanied by coronary spasm sometimes demonstrates ST segment elevation, at other times less impressive changes and, on occasion, no important change. Regardless, the important point is that ECG changes during an episode of chest pain are not a necessary criterion ...
