Cardiac syndrome-X is a clinical entity characterized by angina-like chest discomfort that is often prolonged in duration, normal coronary arteries as assessed by arteriography, non-inducible coronary vasospasm with ergonovine provocation and ST segment depression on treadmill exercise testing. The pathogenesis of cardiac syndrome-X has been ascribed to myocardial ischaemia that may be caused by microvascular dysfunction and increased sensitivity to intracardiac pain. Support for impaired myocardial perfusion in the aetiology of chest pain was provided in a case-control study of 20 patients with established syndrome-X and 10 matched controls that underwent cardiac magnetic resonance imaging at rest and after adenosine infusion.1In syndrome-X patients, adenosine infusion reduced the subendocardial to subepicardial myocardial perfusion index and provoked chest pain in 19
