Abstract 3876: Rapid Increase in the Use of Invasive Cardiac Procedures in the Elderly Following Acute Myocardial Infarction
Data is limited regarding the use of invasive procedures and long term outcome in elderly patients after acute myocardial infarction (AMI).
Methods: All patients admitted with a first AMI in the Province of Quebec, Canada from 1996 to 2004 were identified from provincial physicians’ claims and hospital discharge summary databases. All follow-up admissions and invasive cardiac procedures such as coronary angiograms (Cath), percutaneous coronary intervention (PCI) and coronary bypass surgery (CABG) were recorded. Reliable vital status was obtained in > 99 % of patients.
Results: A total of 109,719 patients were admitted with a first diagnosis of AMI in Quebec. 36% of patients were aged 65–79 years and 21% were ≥ 80 years of age. Rates of cardiac procedures varied according to age group (Table 1⇓), with a 5-fold increase in % Cath and a 9-fold increase in % PCI at 30 days in patients ≥ 80 yrs.
