Comparison of the main clinical, echocardiographic characteristics and leukocyte telomere length between younger and older individuals.

Measurements are shown as means ± SD. LVDD, LV diameter at the end of diastole; LVDS, LV diameter at the end of systole; LVDV, LV end-diastolic volume; LVSV, end-systolic volume; LVMI, LV mass index; EF, ejection fraction; SWT, septal wall thickness; PWT, posterior wall thickness; E, peak early phase filling velocity; A, peak atrial phase filling velocity; DTE, E wave deceleration time; IVRT, isovolumic relaxation time; Em, peak early diastolic mitral annular velocity; Am, peak diastolic mitral annular velocity; S, peak systolic velocity of pulmonary venous flow; D, peak anterograde diastolic velocity of pulmonary venous flow; PV Ar, peak retrograde velocity in late diastole of pulmonary venous flow.
