Echocardiographic parameters reflecting left ventricular diastolic and systolic function differed significantly in healthy octogenarians compared to younger age groups among 248 individuals.
Cross-Sectional (n=248)
Echocardiographic parameters, particularly those reflecting diastolic function and longitudinal systolic function, change significantly with healthy aging, highlighting the need for age-adapted reference values in octogenarians and older individuals.
Aims: Most published material on echocardiographic reference values includes individuals up to the age of 60-70, but reference values for older individuals remain scarce. Accurate interpretation of transthoracic echocardiographic reference values in octogenarians and older individuals requires updated values that reflect healthy ageing. This study aims to compare transthoracic echocardiographic reference values of healthy octogenarians and older individuals with those of younger age groups. Methods and results: A total of 248 individuals were studied. The group was divided into three age categories: sexagenarians, septuagenarians, and octogenarians or older. The participants underwent a standard transthoracic echocardiographic examination according to current guidelines. The main differences between age groups were observed in values related to left ventricular diastolic function. There was a significant difference in some values related to systolic function, such as a significant decrease in mitral annular plane systolic excursion in octogenarians compared to sexagenarians and septuagenarians. Conclusion: The present study showed statistically significant differences in some echocardiographic parameters primarily reflecting the left ventricular diastolic function. In addition, a significant difference in some values related to systolic function were also found. These findings emphasize the need for age-adapted reference values to improve diagnostic accuracy in elderly.
Quintana et al. (Sun,) conducted a cross-sectional in Healthy individuals (n=248). Age (octogenarians or older) vs. Younger age groups (sexagenarians and septuagenarians) was evaluated on Differences in transthoracic echocardiographic reference values. Echocardiographic parameters reflecting left ventricular diastolic and systolic function differed significantly in healthy octogenarians compared to younger age groups among 248 individuals.
