Influence of age on the relationship between left atrial performance and left ventricular systolic and diastolic function in systemic arterial hypertension.

摘要: BACKGROUND Changes in left ventricular (LV) systolic and diastolic properties may generate variations atrial (LA) size function many pathophysiological models of LV overload. Besides these states, increasing age independently influence magnify LA changes. OBJECTIVE To investigate the relation to hypertensive patients, evaluate whether this relationship is influenced by function. METHODS Three hundred thirty-six patients were evaluated using Doppler echocardiography. Maximal volume ejection force used as indexes performance, respectively. RESULTS Age was positively associated with (r=0.34, P<0.001) maximal (r=0.25, P<0.001). The effect independent mass concentric geometry, which parameters. between maintained without dysfunction, those normal function, whereas it lost dysfunction. not either or geometry all groups 56 years older, while no association found variables younger than years. systematically linked classes age, together end-diastolic 68 older. CONCLUSIONS There a positive performance geometry. on insignificant when dysfunction occurs.
