BACKGROUND Aortic counterpulsation has been observed to reduce the rate of reocclusion of the infarct-related artery after patency has been restored during acute myocardial infarction in observational studies. To evaluate the benefit-to-risk ratio of aortic counterpulsation during the early phase of myocardial infarction, a multicenter randomized clinical(More)
BACKGROUND The benefit of catheter-based reperfusion for acute myocardial infarction (MI) is limited by a 5% to 15% incidence of in-hospital major ischemic events, usually caused by infarct artery reocclusion, and a 20% to 40% need for repeat percutaneous or surgical revascularization. Platelets play a key role in the process of early infarct artery(More)
OBJECTIVES This study was undertaken to establish evidence for physiologic activity and to study the safety of murine-derived monoclonal antibody 7E3 Fab (m7E3 Fab) in patients receiving recombinant tissue-type plasminogen activator (rt-PA). BACKGROUND Platelet aggregation is believed to be a significant factor in the failure of pharmacologic reperfusion.(More)
BACKGROUND Smoking is known to be a strong risk factor for premature atherosclerosis, myocardial infarction, and sudden cardiac death. Unexpectedly, in the reperfusion era, investigators have reported that patients who smoke have a more favorable prognosis after thrombolysis compared with non-smokers. Since smoking is associated with a relatively(More)
Options for lower limb percutaneous revascularization are limited especially for complex vessel obstruction. Cutting balloon angioplasty (CBA) has been described in the coronary literature as effective for complex disease. We analyzed our peripheral vascular database and report procedural outcomes along with the clinical success at a mean of 1-year(More)
BACKGROUND Thrombosis has been implicated as central to the clinical complications of coronary angioplasty (PTCA). Chimeric monoclonal 7E3 Fab (c7E3 Fab) is the first of a new class of antiplatelet drugs directed at the platelet glycoprotein IIb/IIIa integrin. This study was performed to determine the pharmacodynamics of c7E3 Fab administration during PTCA(More)
We compared the efficacy of immediate coronary angioplasty after acute myocardial infarction with that of elective angioplasty at 7 to 10 days in patients treated initially with intravenous tissue plasminogen activator. The plasminogen activator (150 mg) was administered 2.95 +/- 1.1 hours after the onset of symptoms, to 386 patients with acute myocardial(More)
OBJECTIVES This study reports on the initial experience with the Gianturco-Roubin flexible coronary stent. The immediate and 6-month efficacy of the device and the incidence of the complications of death, myocardial infarction, emergency coronary artery bypass surgery and recurrent ischemic events are presented. BACKGROUND Abrupt or threatened vessel(More)
Intraaortic balloon counterpulsation (IABP) has been shown to improve coronary artery patency and reduce the rates of recurrent myocardial ischemia and its sequelae in selected patients when used within 24 hours of acute myocardial infarction. The economic implications of prophylactic IABP use are unknown. We obtained hospital bills for 102 patients(More)
