作者以收入监护病房的连续59(男34、女25)例急性心肌梗塞(AMI)患者(65±2岁,均值±标准误,下同)为对象,于发病后48 h内,采用脉冲波多普勒超声心动图(PDE)在心尖四腔观和胸骨旁左室长轴观上探查二尖瓣返流(MR),籍以了解AMI早期MR的发生率并分析MR对重度充血性心力衰竭(CHF)发生发展的影响。 PDE检出MR23例(39％),未检出MR 36例(61％)。MR组同无MR组相比:年龄较大(71±3对62±2岁;p<0.005);非Q波型心肌梗塞相近(10/23对14/36,NS);既往心肌梗塞史较多(8/23对4/36,p<0.05);较多闻及提示MR的收缩期杂音(10/23对6/36,p<0.01);(49例经测定)左室喷血分数<50％者较多(15/19对10/30)且左室喷血分数较低(41.4±4.2％对55.2±2.7％,p<0.005);(38例经
The authors used a continuous wave radio-frequency (pulse wave) method in 59 consecutive (34 males, 25 females) acute myocardial infarction (AMI) patients (65 ± 2 years, mean ± standard error, the same below) Pulmonary echocardiography (PDE) in the apical four-chamber view and parasternal long-axis view of left ventricular mitral regurgitation (MR), membership in order to understand the incidence of early MRI MR and MR analysis of severe congestive heart failure (CHF) the impact of development and development. 23 cases (39%) were detected by PDE and 36 cases (61%) were not detected. MR group compared with no MR group: older (71 ± 3 vs 62 ± 2 years; p <0.005); non-Q wave myocardial infarction was similar (10/23 vs 14/36, NS); history of previous myocardial infarction (8/23 vs 4/36, p <0.05); more pronounced and suggestive of MR systolic murmur (10/23 vs 6/36, p <0.01); (49 cases were measured) left ventricular ejection The scores of <50% were higher (15/19 vs 10/30) and the left ventricular ejection fraction was lower (41.4 ± 4.2% vs. 55.2 ± 2.7%, p <0.005)
