Aging is accompanied by cardiac biological and structural alterations which result in a decrease in diastolic and systolic myocardial functions. Th is study was conducted to assess age-related subclinical changes in left ventricular function using Strain Imaging in healthy elderly individuals with normal left ventricular function by conventional methods (Simpson’s, eyeballing). Th e exclusion criteria were LV myocardial abnormality, valve disease, and atrial fi brillation. Our study included 100 patients divided in 4 groups according to age in years <= 70, 71 to 80, 81 to 90, >= 91; with 25 patients in each group 2D Strain: Comparison of 2D strain values between groups: Global longitudinal strainwas signifi cantly lower in elderly subjects (<= 70-17.95; 71 to 80-17.10; 81 to 90-16.93; >= 91-15.11) P value < 0.05. Th ere was signifi cant diff erence in longitudinal basal, Longitudinal mid, Longitudinal apical region strain rate, showing decreasing trend in all with increase in age (Table).
