Right Ventricular Outflow Tract Acceleration Time: Correlation with Left Ventricular Diastolic Function, Sex, And Age

Background: Pulmonary artery acceleration time (PAAT) can be used as a parameter in the evaluation of pulmonary hypertension and aids left ventricular diastolic function (LVDF) analyses. Objective: To assess whether there is correlation between PAAT LVDF parameters individuals with preserved systolic by sex, age, cardiovascular risk factors. Method: Observational cross-sectional study. One hundred nineteen patients were selected (59 women [49.6%]). The subjects underwent transthoracic echocardiography including measurements PAAT, E A waves E/A ratio, e’ septal lateral E/e’ pressure (PASP), atrial volume. Results: In female patients, positive (Spearman’s coefficient – Spearman [SCC]) was found value (SCC, 0.47; p = 0.002), ratio 0.32; 0.04), 0.36; 0.023), negative PASP -0.43; 0.034). men, no any parameters. Lower values systemic arterial (hypertension) than without (0.13 ± 0.03 s versus 0.16 s; 0.015). Conclusion: present study showed significant some only. Hypertension correlated lower women.
