Coronary occlusion during coronary angiography.
Between January 1, 1970, and December 31, 1974, 2981 patients underwent coronary arteriography. Twelve acute coronary dissections or embolizations occurred, an incidence of 0.4%. The incidences of acute occlusions for the Sones and Judkins techniques were 0.19% (4/2077 studies) and 0.88% (8/940), respectively. No instance of acute occlusion has occurred during the past 490 studies performed by ...
متن کاملThrombocytosis and coronary occlusion.
The differential diagnosis for ST-segment elevation myocardial infarction in young patients without traditional risk factors for coronary artery disease often includes coronary artery vasospasm, dissection, and pericarditis. However, in the setting of focal, sustained arterial closure, one must again revisit a platelet-mediated mechanism. We report a case of platelet-mediated occlusion due to e...
متن کاملCoronary Artery Occlusion
Specific rabbit anti-cardiolipin (anti-CL) antibodies were used to investigate the hypothesis that cardiolipin, associated with mitochondrial membrane proteins, binds Cl and facilitates activation of the complement cascade following reperfusion of ischemic myocardium. By immunoelectron microscopy, anti-CL localized to subsarcolemmal mitochondria, emerging through breaks in membranes of damaged ...
متن کاملCoronary Artery Occlusion
We evaluated the effect of altered loading conditions on left ventricular (LV) diastolic pressurevolume relations during acute coronary artery occlusion that was produced by inflation of an intracoronary balloon. Open-chest anesthetized dogs (n=18) were instrumented so that LV pressure (micromanometer) and LV volume (conductance) could be measured without disturbing the pericardium. The effects...
متن کاملSustained Coronary Occlusion
Background. One or more brief episodes of coronary artery occlusion protect or "precondition" the myocardium perfused by that artery from a subsequent episode of sustained ischemia. We sought to determine whether ischemic preconditioning protects only those myocytes subjected to brief coronary occlusion or whether brief occlusions in one vascular bed also limit infarct size andfor attenuate con...
