Enfarte agudo do miocárdio duplo sequencial

Abstract

Acute myocardial infarction (AMI) involving acute transmural ischemia of two vascular territories at the same time, which is known as double or combined infarction, is a well described phenomenon but rarely reported in most series of patients admitted for AMI. This may be related to the fact that AMI with multiple vessel obstruction often causes extensive myocardial injury and death before the patient arrives at the hospital. It is speculated that double infarction results from the overall prothrombotic and inflammatory conditions associated with AMI.

A Successfully Treated STEMI Due to Simultaneous Thrombotic Occlusion of Left Anterior Descending Artery and Left Circumflex Artery: A Case Report and Review of the Literature

“…While many of them (factors intrinsic to coronary plaques as well as extrinsic forces) have been well described, some mechanisms contributing to plaque instability still have not been fully delineated. Furthermore, multiple plaque ruptures in the setting of STEMI can be not only the effect of simultaneous, but also sequential thrombotic occlusion of two major coronary arteries [7, 8]. The latter is considered to be a consequence of hemodynamic instability and hypotension due to occlusion of one coronary artery, resulting in blood stasis and acute occlusion in another coronary artery with severe underlying lesion [2].…”

A rare case of double infarction treated with primary percutaneous coronary intervention

“…Acute myocardial infarction as a consequence of acute transmural ischemia of two vascular territories at the same time is known as double or combined infarction [ 1 , 2 ]. Although, sometimes, we may find ECG evidence of both anterior and inferior myocardial infarction due to occlusion of “wraparound” LAD, double infarction due to occlusion of two separate vessels is extremely rare.…”

“…Acute myocardial infarction (AMI) involving two or more culprit lesions at the same time, known as double or combined infarction, is an extremely rare event with a grave prognosis [ 1 , 2 ]. Here, we describe a case of a patient with acute myocardial infarction due to total occlusion of the left anterior descending and right coronary artery who presented with cardiogenic shock.…”
