Description

Halkin et al developed a risk score for predicting 1 year mortality following a percutaneous coronary intervention (PCI) in a patient with an acute myocardial infarction based on the CADILLAC Study. The authors are from multiple hospitals in the United States and Spain.


CADILLAC = controlled abciximab and device investigation to lower late angioplasty complications

 

Parameters from multivariate analysis:

(1) baseline left ventricular ejection fraction (LVEF)

(2) renal function

(3) Killip class

(4) final TIMI flow rate

(5) age in years

(6) anemia

(7) extent of coronary artery disease

where:

• Patients with Killip class 4 (cardiogenic shock) are not included.

• 3 vessel disease may include more vessels as well (unless these went to CABG).

 

total score =

= SUM(points for all 7 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 18

• The higher the score the greater the risk of 1 year mortality.
