Embolic Myocardial Infarction as a Consequence of Atrial Fibrillation: A Prevailing Disease of the Future
Acute myocardial infarction (AMI) is a major cause of death and disability worldwide. When spontaneous AMI occurs, there is a greater than 90% chance that the underlying etiology is primary due to coronary events such as plaque rupture, erosion, or dissection referred to as MI Type I 1. Myocardial infarction can also occur secondary to an ischemic insult in the absence of overt coronary artery disease (CAD), by an imbalance between myocardial oxygen supply and/or demand termed type 2 MI, which embodies a myriad of diseases (Table 1). In general, it is estimated that 4 to 7% of all patients diagnosed with AMI however, do not have CAD at coronary angiography or autopsy2.
