ACC/AHA/SCAI 2005 Guideline Update for Percutaneous Coronary Intervention-summary article : A report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (ACC/AHA/SCAI Writing Committee to Update the 2001 Guidelines for Percutaneous Coronary Intervention)

BACKGROUND Blockade of the platelet glycoprotein IIb/IIIa receptor with abciximab (a monoclonal-antibody Fab fragment directed against the receptor) has been shown to diminish ischemic complications among patients undergoing high-risk coronary angioplasty or directional atherectomy but increases bleeding complications. The widespread applicability of this treatment is unknown, particularly in view of the observed risk of hemorrhage. METHODS In a prospective, double-blind trial, we randomly assigned patients undergoing urgent or elective percutaneous coronary revascularization at 69 centers to receive abciximab with standard-dose, weight-adjusted heparin (initial bolus of 100 U per kilogram of body weight); abciximab with low-dose, weight-adjusted heparin (initial bolus of 70 U per kilogram); or placebo with standard-dose, weight-adjusted heparin. The primary efficacy end point was death from any cause, myocardial infarction, or urgent revascularization within 30 days of randomization. RESULTS The trial was terminated at the first interim analysis, with 2792 of the planned 4800 patients enrolled. At 30 days, the composite event rate was 11.7 percent in the group assigned to placebo with standard-dose heparin; 5.2 percent in the group assigned to abciximab with low-dose heparin (hazard ratio, 0.43; 95 percent confidence interval, 0.30 to 0.60; P<0.001); and 5.4 percent in the group assigned to abciximab with standard-dose heparin (hazard ratio, 0.45; 95 percent confidence interval, 0.32 to 0.63; P<0.001). There were no significant differences among the groups in the risk of major bleeding, although minor bleeding was more frequent among patients receiving abciximab with standard-dose heparin. CONCLUSIONS Inhibition of the platelet glycoprotein IIb/IIIa receptor with abciximab, together with low-dose, weight-adjusted heparin, markedly reduces the risk of acute ischemic complications in patients undergoing percutaneous coronary revascularization, without increasing the risk of hemorrhage.

ACC/AHA Guidelines for Percutaneous Coronary Intervention (Revision of the 1993 PTCA Guidelines)—Executive Summary: A Report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Committee to Revise the 1993 Guidelines for Percutaneous Transluminal Coronary Angioplasty) Endorsed by the Society for Cardiac Angiography and Interventions

Effect of transradial access on quality of life and cost of cardiac catheterization: A randomized comparison.

To determine whether complex cardiovascular interventional procedures (including coronary stent implantation, directional atherectomy, aortic valvuloplasty, and the use of an intraaortic balloon pump or cardiopulmonary bypass support) are associated with an increased likelihood of vascular access site complications, 2,400 consecutive cardiac catheterization procedures were prospectively screened over a 12-month study period. Complications occurred in 35 patients after 39 procedures (1.6%) and included the need for vascular surgical repair (17 patients), blood transfusion (28 patients) and systemic antibiotic therapy (7 patients). The incidence of complications after 1,519 diagnostic studies was 0.6%, after 698 conventional coronary balloon angioplasties 2.6%, and after 183 complex interventions 6.0% (p less than 0.0001); 43% of the complications occurred after procedures of greater than 2 hours' duration and 14% occurred in patients in whom arterial sheaths remained in situ for greater than 24 hours. Detailed demographic and procedural characteristics were compared between the 35 patients with vascular complications and 150 patients randomly drawn from a computerized database of the uncomplicated procedures performed during the screening period. By univariate analysis with correction for multiple comparisons, variables predicting the likelihood of vascular complications included: periprocedural use of heparin (p less than 0.001) or fibrinolytic therapy (p less than 0.001), arterial sheath size greater than or equal to 8Fr (p less than 0.001), patient age greater than or equal to 65 years (p = 0.01), and the presence of peripheral vascular disease (p = 0.03). The results of this study suggest that the overall incidence of access site complications is low but increases with the use of complex cardiovascular interventional procedures.(ABSTRACT TRUNCATED AT 250 WORDS)
