Supports age-specific echocardiographic norms in older adults; extends cross-sectional observations but leaves open longitudinal validation.
What are the normal echocardiographic values and their age-related changes in adults without clinically apparent heart disease?
Echocardiographic measurements such as aortic root, left atrial size, and LV wall thickness increase significantly with age in normal adults, while LVEF remains independent of age.
Gardin et al. (1979) studied this question.
