Collateral function in patients with coronary occlusion evaluated by 201 thallium scintigraphy.
The present study evaluated the impact of the angiographically documented collaterals on regional myocardial perfusion measured by 201thallium scintigraphy in patients with a chronic total occlusion. The study included 60 patients with chronic total occlusion who underwent rest-stress myocardial perfusion scintigraphy and coronary angiography. All patients had angiographic evidence of coronary ...
متن کاملThe functional reserve of collaterals supplying long-term chronic total coronary occlusions in patients without prior myocardial infarction.
AIMS Chronic total coronary occlusions (CTOs) with angiographically well-developed collaterals may be considered to provide sufficient blood supply to the occluded segment, and the indication for revascularization may be questioned. Therefore, the collateral function and functional reserve in patients with a CTO without a prior Q-wave myocardial infarction (MI) were assessed. METHODS AND RESU...
متن کاملTiming of coronary collateral appearance during ST-elevation myocardial infarction
Objective: The appearance of collaterals during ST-elevation myocardial infarction (STEMI) and clinical factors potentially associated with their early appearance were studied. Background: The appearance of collaterals is associated with the duration of chronic coronary occlusion. Nevertheless, the question remains as to whether collaterals are already apparent shortly after an acute coronary o...
متن کاملContemporary Reviews in Cardiovascular Medicine Assessment of the Human Coronary Collateral Circulation
Cardiovascular disease is the leading cause of death in industrialized countries and may become the most important reason for mortality worldwide.1 In patients suffering from coronary artery disease (CAD), the size of myocardial infarction mainly determines outcome.2 Accordingly, the primary strategy to reduce cardiovascular mortality is by shrinking infarct size (IS) (Figure 1A).3 In the clini...
متن کاملManagement of a large coronary artery aneurysm with graft-coated stent during the acute phase of myocardial infarction
Coronary aneurysms in adults are rare clinical entities. Herein, we presented a 54-year-old man who was admitted with an acute extensive anterior myocardial infarction. The emergency coronary angiography revealed an isolated large aneurysm at the proximal segment of the left anterior descending coronary artery. The patient was successfully treated with a graft-coated stent
