LEFT ATRIAL STRAIN RESPONSE TO HEART RATE IN PATIENTS AFFECTED OR NOT BY CHRONIC HEART FAILURE: HEMODYNAMIC CORRELATES
Anno:
2023
Background and aim of the study. Previous studies evaluated the effects of heart rate (HR) increase on the left ventricular (LV) function, by two-dimensional longitudinal strain, but many authors also assessed the left atrium (LA) function based on speckle tracking imaging (STI). The LA and LV are connected through the mitral…
