The role of glycoprotein IIb/IIIa platelet inhibition in percutaneous coronary intervention in the stent era.

Journal Article (Review)

In autumn 1996, shortly after the platelet glycoprotein (GP) IIb/IIIa inhibitor abciximab was approved for clinical use by the Health Protection Branch of Health Canada, seven interventional cardiologists met in a roundtable forum to review the use of abciximab in percutaneous transluminal coronary angioplasty (PTCA). While a compelling body of data was presented that argued strongly for adjunctive abciximab in conventional balloon angioplasty, the participants found in difficult to extrapolate the findings to contemporary interventional practice dominated by stent implantation. This uncertainty stemmed from the lack of clinical trials of abciximab during the stent era. Concerns were also raised that the unrestricted use of two expensive therapeutic modalities (stent implantation and GP IIb/IIIa inhibition) would place severe strains on catheterization laboratory budgets. The general consensus was that, pending the availability of further data, abciximab should probably be reserved for selected at-risk patients. This article summarized the roundtable discussions to provide cardiologists' perspectives on the use of abciximab in interventional practice. An overview of platelet physiology and the rationale for GP IIb/IIIa receptor inhibition; a summary of the results of recent randomized clinical trials that assessed the efficacy of abciximab in PTCA; an account of how stents became the most prevalent technique used in coronary intervention; a summary of the available data evaluating abciximab in conjunction with stent implantation; and a synopsis of the conference discussions are included.
