  1. a Mean age of AMI patients = 67.6 (standard deviation 14.2, range 35-104) (Males: 64.3, SD: 13.6; Females: 73.8, SD: 13.1). Mean age of angina patients = 65.0 (standard deviation 12.46, range 35-103) (Males: 63.0, SD: 12.0; Females: 68.0, SD: 12.8).
  2. Notes.
  3. 1. ATSI = Aboriginal or Torres Strait Islander
  4. 2. Comorbidity refers to modified Charlson Index score.
  5. 3. Missing data in AMI patients: SES, n = 148 (2.7%); country of birth, n = 224 (4.0%); area of residence, n = 146 (2.7%); marital status, n = 163 (2.9%); total no. of patients with missing data on at least one variable = 479 (8.7%; 9.2% in males, 7.7% in females). Missing data in angina patients: SES, n = 179 (2.4%); country of birth, n = 273 (3.7%); area of residence, n = 176 (2.4%); marital status, n = 138 (1.9%); total no. of patients with missing data on at least one variable = 554 (7.5%).
  6. 4. Among AMI patients, 99% of those living in major cities, 54% of inner regional patients and 20% of more remote patients were admitted to a metropolitan hospital for the index admission, with corresponding figures for angina patients being 99%, 75% and 41%. All coronary procedures were performed in metropolitan hospitals, with most performed in public hospitals--86% of those in AMI patients and 56% of those in angina patients. Over 90% of AMI patients first admitted to a public hospital also had their procedure in a public hospital, while of those first admitted to a private hospital, 33% had their angiography, 27% their PTCA and 49% their CABG in a public hospital.
