Diastolic dysfunction, often seen with increasing age, is associated with reduced exercise capacity and increased mortality. Mortality rates in older individuals are linked to the development of disability, which may be preceded by functional limitations. The goal of this study was to identify which echocardiographic measures of diastolic function correlate with physical function in older subjects. A total of 36 men and women from the Louisiana Healthy Aging Study, age 62–101 yr, received a complete echocardiographic exam and performed the 10-item continuous-scale physical-functional performance test (CS-PFP-10). After adjustment for age and gender, left atrial volume index (ρ = –0.59; p = .0005) correlated with the total CS-PFP-10 score. Increased left atrial volume index may be a marker of impaired performance of activities of daily living in older individuals.

This study investigated a group of young elite cyclists at the age of 19–20 years. The cardiac characteristics, left ventricular function and structure, after long-term and high intensity endurance training, were examined by echocardiography during resting conditions. In comparison with an age-matched control group, the elite cyclists had significantly lower systolic blood pressure, heart rate, and total body fat and a significantly higher physical fitness. Left ventricular mass, left ventricular mass indexed for differences in body size, and both systolic and diastolic dimensions of the left ventricle were increased significantly in the elite cyclist group. No significant difference was found in left ventricular function. Left ventricular diastolic function was examined (E/A-ratio, E = early passive, A = late active, atriale induced transmitral diastolic flow) and showed no significant difference between the two groups in spite of the structural changes observed in the left ventricular structure. We conclude that structural but not functional cardiac changes can be observed in elite cyclists when examined during resting conditions.

To evaluate the left ventricular diastolic functions, early and atrial transmitral filling peak velocities (Evel and Avel, respectively) and their ratio (Evel/Avel) were collected by using the pulse wave Doppler recording ( Gardin et al., 1986 ; Mulliri et al., 2016
