Left atrial phasic function in hypertensive patients with significant aortic stenosis and preserved ejection fraction.

摘要: The purpose of this investigation was to evaluate the influence hypertension on left atrial (LA) function in patients with moderate and severe AS. This cross-sectional study included 121 AS preserved ventricular (LV) ejection fraction ( > 50%) 79 age-matched controls who underwent a comprehensive echocardiographic examination. LA phasic determined by both volumetric strain methods. Our findings showed that LV similar between hypertensive normotensive patients. Maximal, minimal, pre-A volume indexes gradually increased from moderate-to-severe total, passive active emptying (EF) decreased same direction. estimated analysis reservoir, conduit, pump functions were lower all than controls. However, there no significant difference except function, which Differences more prominent analyses. Blood pressure, mass index, severity independent other clinical parameters associated In conclusion, has an additive impact pressure independently Volumetric assessment should not be completely replaced analysis.
