本文对23例肾动脉狭窄性高血压患者作肾动脉造影,快速静脉尿路造影和血浆肾素活性(包括外周静脉、肾静脉、下腔静脉),并有肾动脉正常的原发性高血压15例进行对比分析,显示快速静脉尿路造影是安全而可靠的筛选检查方法之一,如果以二项或二项以上阳性作标准,则可减少假阳性。血浆肾素活性测定,单项指标阳性意义不大,假阳性与假阴性都很多。若二项或二项以上阳性,则可减少假阳性,因此,如与快速静脉尿路造影结果合并考虑,则诊断意义更大。 相似文献

To determine the relationship between angina pectoris before myocardial infarction (MI) and the extent of coronary artery disease and collateral circulation, 28 patients with (group Ⅰ)and 22 patients without (group Ⅱ) angina one month prior to acute MI underwent left ventriculography and coronary arteriography within 6 months of a first transmural MI. 23 patients in group Ⅰbut only 6 patients in group Ⅱhad multivessel disease. Despite a similar incidence of total occlusion of infarct-related artery, the collateral score in group Ⅰwas significantly higher than that in group Ⅱ. Abnormal regional left ventricular motion score was lower in group Ⅰthan in group Ⅱ. The study suggests that a history of angina before MI may predict the presence o f multivessel disease and the formation of collateral circulation in patients with MI. 相似文献

为了观察AMI患者住院期和出院早期左室舒张功能的动态改变,了解其与冠状动脉病变和梗塞后心绞痛的关系,本文采用二维PDE结合冠脉造影,对40例AMI患者进行了平均6个月的随访观察,结果显示,AMI组无论在住院期和出院早期,其多普勒左室舒张功能指标明显异常于正常组,表现在前者的E峰速度减低,A峰速度增加,E/A和Ei/Ai比值减小(p<0.01)。值得注意的是,梗塞平均6个月后,多项 相似文献

To examine the factors related to left ventricular (LV) aneurysm formation after transmural anterior myocardial infarction (MI), 22 patients with a first attack of anterior MI who underwent left ventriculography and coronary angiography within 6 months of infarction were divided into two groups on the basis of presence (10 patients, Group Ⅰ) or absence (12 patients, Group Ⅱ) of a LV aneurysm. Group Ⅰpatients were shown to have larger infarct and poorer LV function. Single vessel disease and total occlusion of the left anterior descending (LAD) artery were more common and collateral blood supply in the presence of an occluded LAD was significantly less adequate in Group Ⅰcompared with Group Ⅱ. Age, sex and risk factors for coronary artery disease were found to have no correlation with aneurysm formation. It is indicated in this study that total occlusion of the LAD in association with inherent poor collateral blood supply is an important determinant of aneurysm formation after anterior MI. 相似文献

This paper reports two cases of "Torsades depointes" ventricular tachyarrhythmia (TPVT) in particular form. The electrocardiographic characteristicsshowed the presence of abnormally short couplingintervals of premature ventricular contractions(PVCs)as well as the PVCs initiating tachycardias in the set-ting of normal QT intervals. The tachycardias weresusceptible to verapamil and refractory to other an-tiarrhythmic agents. Either triggered activity or re-entry due to slow inward current is considered forthe mechanism of this type of tachyarrhythmia. 相似文献
