[Can changes in diastolic function be predicted according to risk factors?]

Diastolic function has a dynamic behavior according to modifying factors. We describe the variables used in its assessment by echocardiography in different population groups of men and women to determine whether changes can be predicted according to their risk factors.

Observational and descriptive cross-sectional registry. A systematic collection of anthropometric characteristics, risk factors and specific echocardiographic variables of diastolic function was performed in an outpatient echocardiography laboratory. Quantitative variables were expressed as mean and standard deviation for Gaussian distribution variables. Discrete variables were analyzed using contingency tables, qualitative variables are expressed as percentages. Means were compared using the Student t test.

A total of 107 patients were admitted. Those with sedentary lifestyle had a mean left atrial volume of 29 ml/m2, a deceleration time of 218 ms, a transmittal flow ratio E/A (EA) of 1.5, tissue Doppler ratio Ee´ (Ee) of 6 and e´a´ (ea) of 1.4; those who performed physical activity 3 times a week were characterized by having a left atrial volume of 35 ml/m2, a deceleration time of 210 ms, EA of 1.8, Ee of 5 and ea of 1.8. Patients with obesity had a left atrial volume of 35 ml/m2, deceleration time of 226 ms, E/A 1.1, Ee of 9 and ea of 1.2. Those with arterial hypertension had a left atrial volume of 33 ml/m2, deceleration time of 224 ms and E/A ratio of 1, Ee of 8 and ea of 1.

The inclusion of certain risk factors in the history prior to echocardiographic evaluation can predict subgroups with different diastolic function.
