2. Lung transplant candidates referred for invasive coronary angiography which include:

   • Patients with suspicious symptoms for CAD or;
   • Asymptomatic patients;
   • Abnormal non-invasive testing or 1 major risk factor for coronary artery disease or LVEF < 60% on echo in patients with low SVR (typical for ESLD).
