N2 - Background Telomere length has been associated with coronary artery disease and heart failure. We studied whether leukocyte telomere length is associated with left ventricular ejection fraction (LVEF) after ST-elevation myocardial infarction (STEMI).Methods and results Leukocyte telomere length (LTL) was determined using the monochrome multiplex quantitative PCR method in 353 patients participating in the glycometabolic intervention as adjunct to primary percutaneous coronary intervention in STEMI III trial. LVEF was assessed by magnetic resonance imaging. The mean age of patients was 58.9 +/- A 11.6 years, 75 % were male. In age- and gender-adjusted models, LTL at baseline was significantly associated with age (beta +/- A standard error; -0.33 +/- A 0.01; P <0.01), gender (0.15 +/- A 0.03; P <0.01), TIMI flow pre-PCI (0.05 +/- A 0.03; P <0.01), TIMI flow post-PCI (0.03 +/- A 0.04; P <0.01), myocardial blush grade (-0.05 +/- A 0.07; P <0.01), serum glucose levels (-0.11 +/- A 0.01; P = 0.03), and total leukocyte count (-0.11 +/- A 0.01; P = 0.04). At 4 months after STEMI, LVEF was well preserved (54.1 +/- A 8.4 %) and was not associated with baseline LTL (P = 0.95). Baseline LTL was associated with n-terminal pro-brain natriuretic peptide (NT-proBNP) at 4 months (-0.14 +/- A 0.01; P = 0.02), albeit not independent for age and gender.Conclusion Our study does not support a role for LTL as a causal factor related to left ventricular ejection fraction after STEMI.
