Models are adjusted for age, sex, SES, distance to nearest hospital, time from diagnosis of AMI to a procedure (PCI/CABG), severity of coronary disease and comorbid conditions.
PCI: Chinese, n = 139; South Asians, n = 371; White, n = 4219.
CABG: Chinese, n = 43; South Asians, n = 137; White, n = 1507.
*among survivors only, Chinese, n = 123; South Asian, n = 347; White, n = 3879.
**among survivors only, Chinese, n = 31; South Asian, n = 85; White, n = 1010.
