QRS fragmentation does not predict mortality in survivors of acute myocardial infarction

Background Despite advances in coronary revascularization and in heart failure management, myocardial infarction survivors remain at substantially increased mortality risk. Precise risk assessment and risk‐adapted follow‐up care are crucial to improve their outcomes. Recently, the fragmented QRS com...

Description
Summary:Background Despite advances in coronary revascularization and in heart failure management, myocardial infarction survivors remain at substantially increased mortality risk. Precise risk assessment and risk‐adapted follow‐up care are crucial to improve their outcomes. Recently, the fragmented QRS complex, i.e. the presence of additional spikes within the QRS complexes on a 12‐lead electrocardiogram, has been discussed as a potential non‐invasive risk predictor in cardiac patients. Hypothesis The aim of this study was to evaluate the prognostic meaning of the fragmented QRS complex in myocardial infarction survivors. Methods 609 patients with narrow QRS complexes
