【摘要】 目的探讨心房充血分数(AFF)在评价高血压患者左室舒张功能方面的临床应用价值。方法应用声学定量技术(AQ)对40名高血压患者及40名正常人的AAF值,快充血率峰值(PRFR)进行测定,并兼测了二尖瓣口E峰峰值速度与A峰峰值速度比(EV/AV)。结果高血压患者的AFF值明显高于正常人(P<0·001);而PRFR、EV/AV值明显低于正常人(P<0·001~P<0·05)。且所有受试者的AFF值与EV/AV值、PRFR值分别呈负相关(r=-0·51;r=-0·61)。结论AFF能够客观的反映高血压患者的左室舒张功能变化,对鉴别左室舒张功能异常有一定的诊断意义。更多还原

【Abstract】 Objective To evaluate the clinical value of atrial filling fraction(AFF) in detecting left vertricular relaxation function of patients with hypertension. Methods AFF, peak rapid filling rate(PRFR) of 40 patients with hypertension and 40 normal people were measured by acoustic quantification(AQ) technique, and EV/AV of mitral valve were also calculated. Results AFF of patients were higher than normal(P<0.001), while PRFR and EV/AV of patients were lower than normal(P<0.001～P<0.005). Moreover, AFF of the whole subjects have negative correlations with PRFR and EV/AV respectively(r=-0.51, r=-0.61). Conclusion AFF can objectively show changes of left ventricular relaxation function in patients with hypertension, it is useful in identification of abnormality of left ventricular relaxation function.更多还原
