Patient treatment was performed according to current standard practice. The choice of treatment strategy, type, diameter, and length of stents, the use of medications, intravascular imaging devices, thrombus aspiration, or hemodynamic support devices were left to the operator’s discretion. Unless there was an undisputed reason for discontinuing dual antiplatelet therapy, all patients were recommended to be given aspirin indefinitely plus clopidogrel or other potent antiplatelet agents, such as prasugrel or ticagrelor, for at least 1 year. Choice of P2Y12 inhibitors prescribed was left to operator’s discretion in accordance with the guidelines and patient bleeding risk.
Demographic features and cardiovascular risk factors were collected by patient interviews or review of medical records. During hospitalization, findings of coronary angiography and detailed procedural characteristics of percutaneous coronary intervention as well as information on discharge medications were collected. All patients were recommended to perform echocardiography during index admission and during the follow-up period annually after AMI using commercially available ultrasound systems. Assessment of systolic function was performed according to ASE/EACVI recommendations17 (link). Follow-up data was recorded during the 36-month of follow-up after discharge. The data was completed by telephone interview if patients did not visit on their scheduled day of follow-up. Using a web-based case report form in the internet-based Clinical Research and Trial management system (iCReaT), independent clinical research coordinators collected all baseline data and clinical events up to 36-month follow-up (iCReaT Study No. C110016).
