Use the Vascular Study Group of New England Cardiac Risk Index (VSG-CRI) to estimate post-operative in-hospital major cardiac event after endovascular infrarenal AAA repair (EVAR).


Congestive heart failure?
Cardiac Stress Test [Definition]
Clopidogrel use? [Definition]
AAA size


Cardiac stress test includes stress EKG, stress echo or nuclear stress scans within 2 years of surgery.
Clopidogrel use would be selected if clopidogrel taken within 36 hours of surgery.


About this calculator

The Revised Cardiac Risk Index (RCRI) is a widely used model for predicting cardiac events after noncardiac surgery. However, it substantially underestimates in-hospital cardiac events in patients undergoing elective or urgent vascular surgery, especially after lower extremity bypass, endovascular abdominal aortic aneurysm repair and open infrarenal abdominal aortic aneurysm repair. The Vascular Study Group of New England Cardiac Rsk Index (VSG-CRI) more accurately predicts in-hospital cardiac events after vascular surgery.
