Normal angiography but severe hypokinesia of LV wall is seen in NOT RELATED-MEDICINE

Tako-Tsubo (Stress) CardiomyopathyAbrupt onset of severe chest discomfo preceded by a very stressful emotional or physical event.Women >50 years, ST-segment elevations and/or deep T-wave inversions in the precordial leads.Normal angiography.Severe akinesia of the distal poion of the left ventricle with reduction of the EF.Troponin are usually mildly elevated.Cardiac imaging typically shows "ballooning" of the left ventricle in end-systole, especially of the LV apex. All of these changes, which are often quite dramatic, are reversible within 3-7 days and do not cause long-term cardiac dysfunction or disability.The mechanism responsible for Tako-tsubo cardiomyopathy is that an adrenergic surge that includes circulating catecholamines, acting on the epicardial coronary vessels and/or coronary microcirculation, is involved.Beta blockers are used in therapy.
