Potassium channel activators in vasospastic angina
European Heart Journal, 1993Activation of potassium channels induces relaxation of vascular smooth muscle, and experimental studies have demonstrated that potassium channel activators have potent coronary vasodilator properties. In humans, nicorandil, a potassium channel blocker, causes vasodilatation not only in angiographically normal segments but also at sites of dynamic ...

Clandestine ischemia in patients with vasospastic angina
Coronary Artery Disease, 2000Coronary vasospasms generally occur at rest, but can also be triggered by physical exercise. Anginal pain and ST-segment elevation may be seen during exercise-stress tests. ST-segment depression, due to nonocclusive vasospasms, has also been found to occur. When the result of a test is positive, scintigraphy usually reveals perfusion defects.

Vasospastic Angina in Thyrotoxicosis—Case Reports
Angiology, 1987We encountered 2 patients with thyrotoxicosis accompanied at its onset by progressive angina. The ST segment was elevated in one patient and depressed in the other patient during the spontaneous attacks. Coronary arteriographic findings were normal during control, and spasm was induced by ergonovine.

Vasospastic angina is associated with ventricular arrhythmias, acute myocardial infarction and sudden arrhythmic death. The main ischemic mechanism in vasospastic angina is coronary spasm. Because the demonstration of spontaneous coronary spasm is difficult, a number of methods which can provoke spasm in susceptible patients were imagined.

Allergic vasospastic angina: a systematic review
HeartBackground Allergic vasospastic angina (also referred to as Kounis syndrome) is an under-recognised subtype of vasospastic angina in which coronary artery spasm is precipitated by an allergen. This study evaluates the clinical characteristics, mechanisms and management of this intriguing angina subtype.
