DERIVATION Score of Capodanno et al for Risk of Stent Thrombosis

Purpose: To identify a patient at risk for thrombosis of a drug-eluting stent placed in a coronary artery using the DERIVATION score of Capodanno et al.

Description

Capodanno et al developed a score for predicting the risk of stent thrombosis following percutaneous coronary artery intervention with a drug-eluting stent. The authors are participants in the DES Real-world Incremental Value in the erA of percutaneous revascularization (DERIVATION) study at the University of Catania in Italy.


Patient selection: following percutaneous placement of one or more drug-eluting stents

 

Parameters:

(1) baseline left ventricular ejection fraction (LVEF)

(2) acute coronary syndrome

(3) treated vessel

(4) bifurcation lesion

(5) number of stents placed

= SUM(points for all 5 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 13

• The higher the score the greater the risk of stent thrombosis.

• A patient at increased risk for stent thromobosis may benefit from more aggressive management to prevent thrombosis.
