Abstract 11695: The Kinetics of Circulating Monocyte Subsets and Microbial Translocation in the Acute Phase of ST-Elevation Myocardial Infarction Reveals Prognostic Values for Cardiovascular Outcomes
2015
Introduction: In experimental myocardial infarction (MI), a rise in cell counts of circulating monocyte subsets contributes to impaired myocardial healing, and to atherosclerotic plaque destabilization.The underlying pathophysiological mechanisms for the post-MI monocytosis and the prognostic role of monocyte subsets in patients suffering ST-elevation MI (STEMI) are still unclear. Hypothesis: The kinetics of the three monocyte subsets (classical CD14++CD16-, intermediate CD14++CD16+ and non-classical CD14+CD16++ monocytes) and gut microbial translocation are associated with cardiovascular outcomes after STEMI. Methods: In 100 STEMI patients treated with primary percutaneous coronary intervention (PCI), monocyte subsets and microbial translocation markers (lipopolysaccharide [LPS] and D-lactate) were measured on Days 1, 2, 3, 5 and 7 of STEMI onset, compared with 35 stable coronary heart disease patients and 35 healthy volunteers. All STEMI patients were prospectively followed for the first occurrence of a...
