Current Treatment Options in Cardiovascular Medicine, 2000
Attacks of variant angina usually respond promptly to sublingual administration of short-acting nitrates (nitroglycerin, 0.3 to 0.4 mg, or isosorbide dinitrate, 5 to 10 mg), which may be repeated after 3 to 5 minutes if pain persists. In the rare cases resistant to sublingual nitrates, sublingual nifedipine (5 to 10 mg) or, when readily available ...

OESOPHAGEAL SPASM IN PATIENTS WITH CORONARY ARTERY SPASM
The Lancet, 1986Oesophageal manometry was performed in 20 patients with chest pain, of whom 10 showed coronary artery spasm (group I) and 10 did not (group II). In the basal state oesophageal spasms were recorded in 6 patients from group I but in none from group II (p less than 0.05).

Coronary spasm in patients with coronary ectasia
Catheterization and Cardiovascular Diagnosis, 1994AbstractThe incidence of coronary ectasia (CE) and the relationship between CE and coronary spasm that was said not to be apt to occur in patients with CE were studied. The study consisted of 1,373 patients (including 1,008 patients with ischemic heart disease) who underwent cardiac catheterization.

C oronary vasospasm has become accepted as a cause of “variant” angina, and it has also been convincingly demonstrated in angina with S-T segment depression. This mechanism of angina, postulated over a century ago, fell into disrepute when nearly all patients with angina were found to have severe coronary atherosclerotic narrowing at autopsy.

Stenting for coronary artery spasm
Catheterization and Cardiovascular Interventions, 2002AbstractWe evaluated coronary stenting in nine patients with clinically severe, angiographically documented spasm refractory to aggressive pharmacologic management. No patient subsequently developed unstable ischemia requiring hospitalization as a consequence of recurrent spasm within the stent. Mechanisms of therapeutic failure included both peristent

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 ...

Coronary spasm provoked by angiography
American Heart Journal, 1984nitroglycerin.5 Both intranvenous and intracoronary nitroprusside have been shown to dilate coronary arteries in experimental preparation. 6.7 Clinically, intravenous nitroprusside has been used to relieve angina, ST-segment elevation, and ventricular arrhythmias in hypertensive patients.* Intracoronary nitroprusside similarly has been used in the ...

Familial catamenial coronary spasms
BMJ Case ReportsCoronary artery spasms represent important causes of myocardial ischaemia and infarction in patients with non-obstructive coronary artery disease. They are notably seen in younger people and occur almost equally in men and women. Besides traditional risk factors (ie, smoking), female hormones might also play a role.
