Abstract 18029: Left Ventricular Systolic Strain in Older Subjects with No Known Cardiac Disease

Introduction: It is known that with increasing age impaired myocardial relaxation increases, while systolic function is preserved. We hypothesize that there is, in fact, subclinical left ventricular (LV) systolic dysfunction in older subjects. We test this hypothesis by assessing LV systolic strain using velocity vector imaging in older subjects with no known cardiac disease. Methods: One-hundred and ninety consecutive subjects with no known...
