LTL in AF patients and the controls. (a) AF patients showed significantly shorter LTL compared with controls; (b) quartile distribution of LTL; (c) LTL in elderly males was significantly negatively correlated with age; (d) LTL was significantly shorter in AF patients in the elderly age group and senile age group; (e) there were no significant differences of LTL among the paroxysmal AF, persistent AF, and permanent AF groups. LTL: leukocyte telomere length; AF: atrial fibrillation; Q: quartile.
