Primary percutaneous intervention (pPCI) was introduced 2\u2009years after start of the enrolment, dividing the population into two groups: pre- and post-pPCI. This substudy sought to describe the influence of the mode of revascularization on long-term risk of new-onset atrial fibrillation (AF), bradyarrhythmia, and ventricular tachycardia and the subsequent risk of relevant major cardiovascular events (MACE).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>The study included the 268 patients without a history of AF. All patients received an implantable cardiac monitor (ICM) and were followed for 2\u2009years. The choice of revascularization was made by the treating team independently of the trial and retrospectively divided into pPCI, subacute PCI, primary thrombolysis, or no revascularization. Endpoints were new-onset arrhythmia and MACE.<\/jats:p>\n                  <jats:p>A total of 77 patients received no revascularization, whereas 49 received thrombolysis only and 142 received any PCI. The adjusted hazard ratio (HR) for developing any arrhythmia and the subsequently risk of MACE were increased in non-revascularized or thrombolysed patients compared with PCI-patients (any arrhythmia, non-revascularization: HR\u2009=\u20091.7, P\u2009=\u20090.01 and thrombolysis: HR\u2009=\u20091.6, P\u2009=\u20090.05; MACE, non-revascularization: HR\u2009=\u20093.1, P\u2009=\u20090.05 and thrombolysis: HR\u2009=\u20093.1, P\u2009=\u20090.08).
