BACKGROUND: Increasing evidence suggests that @entity32 plays an important role in initiation and maintaining of @entity955 ( @entity955 ). The Neutrophil to Lymphocyte (N/L) Ratio is an easily derived and readily available parameter that has emerged as marker of @entity32 with predictive and prognostic value. We investigated the association between N/L ratio and incidence of @entity955 in @entity1 undergoing cardiac catheterization for acute ST-segment elevation @entity583 (STEMI. METHODS: This cross sectional descriptive study was carried out at New York Hospital Queens. We retrospectively analysed clinical, hematologic and angiographic data of 290 @entity1 who underwent coronary angiography with stent placement for acute ST-segment elevation @entity583 between 2008-2011. RESULTS: Study cohort of 290 @entity1 had mean age 63.3 +/- 13.0 years consisting of 81.4% male. The N/L ratio was measured at time points: <6 hours precatheterization, <12, 48 and 96 hours post catheterization. @entity1 who developed @entity955 (n=40, 13.8%), had higher post catheterization N/L ratios at 48 hours (median 5.23 vs. 3.00, p=0.05) and 96 hours (median 4.67 vs. 3.56, p=0.03), with no differences in the immediate pre and post procedural measurements, <6 hours pre catheterization (median 2.49 vs. 2.82, p=0.467) and <12 hours post catheterization (median 5.93 vs. 5.03, p=0.741) respectively. CONCLUSION: In conclusion, these findings support an inflammatory aetiology contributing to new onset @entity955 following percutaneous coronary intervention for acute STEMI. Further studies are warranted to elucidate these findings.
