Age-standardised rates of admission for coronary artery revascularisation procedures in males aged 35 years or older in Western Australia during 1980-2005. CARP = total PCI + CABG; Total PCI = Stents + PTCA; PTCA, percutaneous transluminal coronary (balloon) angioplasty. Curves for females show a similar pattern. Although stents were available in Western Australia in 1988, there was little uptake until 1994, and there was no ICD-9-CM code until July 1995.
