Objectives: To determine the influence of aging on measured left ventricular (LV) diastolic parameters using healthy subjects aged 40-79 years. To propose age-related reference values for LV filling pressure, LV isovolumic relaxation time (LV IVRT) and myocardial stiffness index for each decade using pulsed waved tissue Doppler.
Background: Pulsed wave tissue Doppler parameters have been used for over a decade in the clinical setting as an aid to the evaluation of diastolic function and filling pressures, however there is limited information on normal reference ranges especially in middle age and the older person.
Methods: Subjects with no …
