The role of infarction-associated pericarditis on the occurrence of atrial fibrillation

Abstract

Among patients with infarction-associated pericarditis, those with PQ-segment depression represent atrial involvement associated with extensive myocardial damage and hence, PQ-segment depression is one of the clinical signs related to the occurrence of atrial fibrillation in acute Q-wave myocardial infarction.

Relationship of functional mitral regurgitation to new-onset atrial fibrillation in acute myocardial infarction

“…The mechanisms that promote the development of AF in the AMI setting are complex and often multifactorial. Many potential mechanisms have been implicated, including pericarditis, atrial ischaemia or infarction, increased catecholamines, metabolic abnormalities, inflammation and increased atrial pressures 2 16 17. Experimental and clinical observations suggest that increasing atrial pressure and/or causing acute atrial dilatation may play an important role.…”

Association Between Serum C‐reactive Protein Elevation and Atrial Fibrillation After First Anterior Myocardial Infarction

“…In previous studies, AF was frequently associated with advanced age in patients with MI. 8,17 Atrial fibrillation in the elderly may be related to the increased incidence of agerelated coexisting pathologic changes in the noninfarcted myocardium and atrial tissue. In patients with AMI, the multiple etiological factors of atrial arrhythmias have been documented.…”

Calcified Pipes

“…[6][7][8][9] Animal models of atrial ischemia have shown increased spontaneous atrial ectopic activity and slowing of atrial conduction, leading to initiation and sustained re-entry of AF. Coronary artery calcium (CAC) scores can identify vascular aging and patients at risk for acute coronary events.…”
