【摘要】 本文用心尖搏动图舒张振幅时间指数(DATI)评定70例高血压病及34例冠心病患者的左室舒张功能,并与正常对照组比较。两组患者的 DATI、总舒张时间指数(TARTI)及 A 波与全舒张期高度比(A/D)的均值均有显著改变(P<0.01),且高血压病在心脏增大以前即有舒张功能改变。DATI 异常的检出率高(P<0.01),可作为评定左室舒张功能的敏感指标,对冠心病的诊断有一定的意义。更多还原

【Abstract】 The left ventricular diastolic function of 70 patients with essential hyperten-sion and 34 patients with coronary artery disease（CAD）was assessed by diastolicamplitude time index（DATI）of apexcardiogram in comparison with 48 normalcontrols.Total apexcardiographic relaxation time（A₂O）prolonged only in stage Ⅱhypertension（P<0.05）.There was no significant difference in hypertension andCAD comparing with normal controls in regard to diastolic duration（A₂C）.A/Dincreased significantly（P<0.01）,total apexcardiographic relaxation time index（TARTI）and DATI decreased significantly（P<0.005-0.01）in hypertension andCAD.Abnormal A/D,TARTI and DATI in hypertension were 37.1%,28.6% and50.0%;and those in CAD 38.2%,26.5% and 44.1% respectively.All showedstatistical significance as compared with the normals.There was a high incidenceof abnormal DATI of both groups in patients.It is concluded that left ventriculardiastolic function was impaired in CAD and hypertension even prior to cardiacenlargement.DATI can be considered as a sensitive index in the assessment of leftventricular function and may be of diagnostic significance for CAD.更多还原
