The National Cardiovascular Data Registry (NCDR) was used to develop a model for predicting mortality associated with percutaneous coronary intervention (PCI). The authors are from multiple hospitals in the United States.
Parameters:
(1) age I years
(2) cardiogenic shock
(3) history of congestive heart failure (PCI)
(4) peripheral vascular disease (PVD)
(5) chronic lung disease
(6) glomerular filtration rate (GFR) from MDRD in mL per min per 1.73 square m BSA
(7) NYHA functional class IV
(8) PCI and STEMI status

total score =
= SUM(points for all 8 parameters)
Interpretation:
• minimum score: 0
• maximum score: 117 (scoring was done over a range of 0 to 100)
• The higher the score the greater the risk of in-patient mortality.

Purpose: To predict in-hospital mortality for a patient undergoing percutaneous coronary intervention (PCI) using the NCDR CathPCI risk score.
