摘要
对29例二尖瓣狭窄(MS)患者,运用多普勒超声心动图测量二尖瓣口面积,放免法测血浆心钠素(ANF)浓度,发现二者弱相关,并以 MS 组中 ANF 高于正常值的 X^-+2SD 值来预测临界性二尖瓣狭窄,其敏感性69%,特异性71%。
Twenty-nine patients with mitral stenosis(MS)were studied for measuring mit-ral valvular area(MVA)by Doppler ultracardiography,and the concentration ofatrial natriuretic factor(ANF)by radioimmunoassy.The results showed,there wasa weak relationship between MVA and ANF in MS and 9 NS1 groups(r=-0.44,P<0.005, n=38).Furthermore,a value of ANF higher than (?)+2SD of control couldpredict critical mitral stenosis,with a prognostic sensitivity of 69%,and specialityof 71%.
