Abstract

Background: Previous studies have examined medication use among patients with coronary artery disease who have suffered an acute myocardial infarction (MI). However, little is known about medication use among patients with coronary artery disease who undergo percutaneous coronary intervention (PCI). Objective: To examine the patterns of use of medical therapy among patients who undergo PCI; and to examine the determinants of medical therapy in these patients. Methods: The Routine versus Selective Exercise Treadmill Testing after Angioplasty (ROSETTA) registry is a prospective multicentre study examining the use of functional testing after PCI. The medication use was examined among 787 patients who were enrolled in the ROSETTA registry at 13 clinical centres in five countries. Results: Most patients were men (mean age 61±11 years, 76% male) who underwent single vessel PCI (85%) with stent implantation (58%). At admission, discharge and six months, rates of acetylsalicylic acid use were 77%, 96% and 93%, respectively (discharge versus six months, P<0.0001). Rates of use of other oral antiplatelet agents were 11%, 59% and 2% (P=0.02). For individual anti-ischemic medications, rates of use were as follows: beta-blockers 49%, 58% and 59% (P<0.0001); calcium antagonists 34%, 43% and 42% (P<0.0001); and nitrates 42%, 56% and 43% (P<0.0001). Rates of use of combination anti-ischemic medications were as follows: triple therapy 7%, 9% and 9% (P<0.0001); double therapy 34%, 47% and 38% (P<0.0001); monotherapy 36%, 36% and 41% (P<0.0001); and no anti-ischemic therapy 23%, 8% and 12% (P<0.0001). Rates of use of angiotensin-converting enzyme inhibitors were 25%, 33% and 32% (P<0.0001), and rates of use of lipid lowering agents were 41%, 52% and 61% (P<0.0001). Conclusions: Trials and guidelines statements have favourably affected the rates of use of acetylsalicylic acid and other antiplatelet agents after PCI. However, in spite of patients undergoing a successful revascularization procedure, physicians do not reduce the use of anti-ischemic medical therapy.
