A New Tool for Detecting Jeopardized Myocardium After Thrombolytic Therapy
Background. We wished to assess whether dipyridamole echocardiography test (DET) can detect jeopardized myocardium after thrombolytic therapy. Methods and Results. Seventy-six consecutive patients with a first acute myocardial infarction (AMI) were treated with 2 million IU urokinase i.v. within 4 hours of the onset of AMI and underwent high-dose (as much as 0.84 mg/kg over 10 minutes) DET 8-10...
متن کاملAssessment of jeopardized myocardium in patients with one-vessel disease.
The size of the perfusion defect was assessed from a quantitative analysis of exercise thallium201 images. Quantitative analysis was determined by measuring the area and the perimeter of the perfusion defect and expressing it as a percentage of the total left ventricular area or perimeter in three projections. Using this technique, we studied 50 patients with one-vessel disease of50% or greater...
متن کاملFunctional improvement of jeopardized myocardium following intracoronary streptokinase infusion in acute myocardial infarction.
The effect of reperfusion on regional left ventricular performance following acute myocardial infarction in man was determined. Intracoronary streptokinase was administered in 24 patients within 6 h of the onset of symptoms. 15 patients (62%) were successfully recanalized during the initial study. Mean percent radial shortening (%RS) in both the jeopardized and compensatory regions were determi...

متن کاملThe loss of radioactive microspheres from canine necrotic myocardium.
To verify whether there is a loss of radioactive microspheres (RM) from regions undergoing myocardial infarction, we injected 7-10 fan RM into the left atrium in 75 dogs before left circumflex (LC) coronary artery occlusion and measured the myocardial RM content when the dogs were killed 696 hours later. The preocclusion RM content per gram in the occluded LC bed was not significantly different...
