Correlations between Inflammation and Thrombosis in the Pathogeny of Myocardial Infarction

Abstract

Atherosclerosis is the main cause of myocardial infarction. This process involves a complex interplay between metabolic pathways governing lipid deposition, inflammatory and immune responses to oxidized lipids, and endothelial dysfunction. Myocardial infarction appears when these processes culminate with a thrombotic event. Markers of inflammation, such as C-reactive protein (CRP), myeloperoxidase (MPO) and leukocyte levels are strong predictors of cardiovascular death, myocardial infarction, and stroke. This process involves a complex interplay between metabolic pathways governing lipid deposition, inflammatory and immune responses to oxidized lipids, and endothelial dysfunction. Myocardial infarction appears when these processes culminate with a thrombotic event. Markers of inflammation, such as C-reactive protein (CRP), myeloperoxidase (MPO) and leukocyte levels are strong predictors of cardiovascular death, myocardial infarction, and stroke. This review will summarize the molecular and cellular links between inflammation and thrombosis in the context of myocardial infarction, which support the concept of a thrombo inflammatory state leading to the vessel obstruction and to the subsequent myocardial necrosis.
