Syndrome X is a cardiac microvascular dysfunction or constriction that causes in patients with normal epicardial coronary angina pectoris. (See also Overview of coronary heart disease.) Patients with cardiac syndrome X have typical angina relieved by rest or nitroglycerin Normal koronarangiographischer findings (z. B. no evidence of atherosclerosis, embolism or inducible Koronargefäßspasmen). Some of these patients have an ischemia was diagnosed with a stress test, others do not. In some patients the cause of ischemia seems to be a reflex intramyocardial Koronarkonstriktion and reduced coronary flow reserve. Others have a microvascular dysfunction within the myocardium: the pathological vessels do not dilate during exercise or other cardiovascular stress factors. The sensitivity of chest pain may be increased. This condition should not be confused with variant angina that occurs as a result of epicardial Koronargefäßspasmen. Also this syndrome X should not be confused with another syndrome X, which, however, refers to the metabolic syndrome. The prognosis is better for patients with coronary artery disease, although the symptoms of ischemia can occur over years back. In many patients, beta blockers relieve symptoms.
