Ito et al reported a risk score for patients undergoing percutaneous coronary intervention with drug-eluting stent placement. The authors are participants in the STENT (Strategic Transcatheter Evaluation of New Therapies) group from multiple hospitals in the United States.
Patient selection: percutaneous coronary intervention (PCI) with placement of a drug-eluting stent (DES)
Outcome: major adverse cardiac or cerebrovascular event (MACCE) within 30 days
Parameters:
(1) cardiogenic shock
(2) acute congestive heart failure
(3) pre-procedural statin use
(4) hemoglobin in g.dL
(5) left main coronary artery disease
(6) left anterior descending (LAD) coronary artery diseaes
(7) ostial lesion
(8) ACC/AHA type C lesion
(9) coronary artery thrombosis

total score =
= SUM(points for all 9 parameters)
Interpretation:
• minimum score: -2
• maximum score: 33
• The higher the score the greater the risk for a major adverse event.
