主 题：Diastolic function Left ventricular filling pressure Racial differences
摘 要：Background Left ventricular filling pressure(LVFP)is an important early indicator of heart failure that is more prevalent in Caucasians than ***-induced change in LVFP may provide more incremental information to assess dias-tolic *** it was unknown whether there was difference in LVFP following acute exercise between Caucasians and *** The purpose of this study was to investigate the change of LVFP following an acute 45-min aerobic exercise in healthy Caucasian and Chinese *** Sixty participants(30 Caucasians and 30 Chinese,half was male,respectively)performed an acute bout of aero-bic exercise at 70%of heart rate ***,Left ventricle(LV)morphology and function parameters were measured at baseline,then at 30-min and 60-min *** There was a similar LV ejection fraction,LV fraction shorten,lateral E/eʹand lateral eʹbetween Chinese and Caucasians at *** was a significant race-by-time interaction in lateral E/eʹand lateral eʹbetween Chinese and Caucasians from pre-exercise to 30 min and 60 min after acute aerobic ***ΔE/eʹwas significant correlated with baseline systolic blood *** The change of LVFP was different between Chinese and Caucasians following acute aerobic *** racial differences may be primarily caused by the changes of LV relaxation following exercise,baseline systolic blood pressure may also contribute to the differences.
