STUDY OBJECTIVE
Infarct size is a strong predictor of outcomes after ST elevation myocardial infarction (STEMI). Circulating fibrocytes are bone marrow-derived progenitor cells associated with fibrotic processes. We tested whether fibrocytes correlate with infarct size in STEMI patients treated with primary percutaneous coronary intervention (PCI).
DESIGN
Prospective observational study.
SETTING
Academic medical center.
PARTICIPANTS
Subjects with STEMI treated with primary PCI.
INTERVENTIONS
Peripheral blood draw and cardiac magnetic resonance imaging (CMR).
MAIN OUTCOME MEASURE
Correlation of fibrocyte levels with infarct size.
METHODS
Peripheral blood fibrocytes were quantified at discharge from STEMI hospitalization and at 6 months follow-up using flow cytometry. Infarct size was determined within 2 weeks of discharge and at 6 months follow-up using late gadolinium enhancement on CMR.
RESULTS
Among 14 patients (median age 54 years, 79% men) with STEMI, there was a statistically significant positive correlation between fibrocyte levels at 6 months and 6-month infarct size on CMR (r = 0.58, p = 0.031). In addition, there was positive correlation between peak troponin I level (r = 0.85, p < 0.001), and white blood cell count (r = 0.55, p = 0.042) during the hospital stay and 6-month infarct size on CMR.
CONCLUSIONS
Circulating fibrocytes measured 6 months after STEMI positively correlate with 6-month infarct size assessed by CMR.
