Q: What is NCDR CathPCI risk score?

Answer:  National Cardiovascular Data Registry (NCDR) for percutaneous coronary intervention (PCI) is a model to predict initial risk in patients with coronary artery disease undergoing PCI. It  was developed from little less than 200,000 patients over 3 years across United States. It took into account of 21 variables including age, CHF status, renal insufficiency, PVD, respiratory status, and level of EKG status (STMI or NSTMI), and others.

It is a very strong data (C-Index). Patients were equally divided into two arms - patients with acute coronary syndrome and stable patients. Overall in-hospital mortality following PCI was 0.65 percent in elective cases and 4.81 percent in ST-elevation MI patients.
