Type 2 myocardial infarction in COVID19: World's first case series

ABSTRACT

Type 2 Myocardial Infarction is characterized as a myocardial infarction which is caused by factors other than Coronary Artery Disease (CAD). The causative factor for a secondary myocardial infarction is a disbalance between oxygen supply and its demand. There have been cases where there was 90% blockage in the coronaries but still myocardial infarction was classified as type 2 as the causative factor was not Coronary artery disease but the disbalance between oxygen demand and supply. Thus there is a diagnostic challenge with considerable overlap in Type 2 and Type 1 Myocardial Infarction. COVID19 has brought a tremendous load on healthcare ever since it's identification in the late 2019. There is increased demand of Oxygen due to hypoxia caused by severe pneumonia leading to a disbalance between oxygen supply and demand causing a type 2 myocardial infarction, though the cases of Type 1 myocardial infarction due to COVID19 are well documented this is the first case series showing Type 2 myocardial infarction in the world to our knowledge.
