Values are mean ± SD or n (%).

BMI = body mass index; CAD = coronary artery disease.

  • * Calculated as weight in kilograms divided by height in meters squared.

  • Patients referred for angiography from the emergency department (ED).

  • Defined by quantitative conventional coronary angiography (CCA).
