Two-hundred patients with TTS will be randomized (1:1) to BB (n=100) or no BB (n=100). BB with alpha or nitric oxide release activity will be used in the treatment arm. The primary endpoint will be the comparison of the wall motion score index by echocardiography at 7 days. A composite clinical endpoint (death, stroke, admission for recurrent TTS, ACS, heart failure or atrial fibrillation) at 1 year, will be assessed by an independent clinical events committee. Several sub-studies will be performed. The β-Tako trial will inform treatment decisions in this uniquely challenging clinical entity.",[27,28,29,30],"Takotsubo Cardiomyopathy","Beta-blockers","Echocardiography","Left Ventricular Function",[27,32,33,34,35,36,37,38,39,40],"beta-blockers","echocardiography","left ventricular function","acute myocardial infarction","acute coronary syndrome","coronary angiography","Normal coronary arteries","Heart failure","stress","NOT_YET_RECRUITING","2024-08-21",{"date":44,"type":45},"2024-08-26","ACTUAL",{"date":47,"type":21},"2024-08",{"date":49,"type":21},"2026-12",{"name":51,"class":52},"Spanish Society of Cardiology","OTHER","Beta Blockers"]
