title: The number of circulating CD14(+) cells is related to infarct size and postinfarct volumes in ST segment elevation myocardial infarction but not non-ST segment elevation myocardial infarction.
abstract: OBJECTIVE
  To determine the relationship between the number of CD14(+) cells, myocardial infarct (MI) size and left ventricular (LV) volumes in ST segment elevation MI (STEMI) and non-ST segment elevation MI (NSTEMI) patients.
  
  
  METHODS
  A total of 62 patients with STEMI (n=34) or NSTEMI (n=28) were enrolled. The number of CD14(+) cells was assessed at admission. Infarct size, left ventricular ejection fraction (LVEF) and LV volumes were measured using magnetic resonance imaging five days after MI and six months after MI.
  
  
  RESULTS
  In STEMI patients, the number of CD14(+) cells was positively and significantly correlated with infarct size at day 5 (r=0.40; P=0.016) and after six months (r=0.34; P=0.047), negatively correlated with LVEF at day 5 (r=-0.50; P=0.002) and after six months (r=-0.46; P=0.005) and positively correlated with end-diastolic (r=0.38; P=0.02) and end-systolic (r=0.49; P=0.002) volumes after six months. In NSTEMI patients, no significant correlation was found between the number of CD14(+) cells and infarct size, LVEF or LV volumes at day 5 or after six months.
  
  
  CONCLUSIONS
  The number of CD14(+) cells at admission was associated with infarct size and LV remodelling in STEMI patients with large infarct size, whereas in NSTEMI patients, no relationship was observed between numbers of CD14(+) cells and LV remodelling.
