2006-2008 Risk Factors for PCI In-Hospital/30-Day Mortality (ALL CASES)
e significant pre-procedural risk factors for in-hospital/30-day mortality following PCI in the 2006-2008 time period
are presented in the table that follows. e interpretation of this table is similar to the interpretation of Appendices 1 and 2 that are described previously. All variables except Female Gender, Cerebrovascular Disease, Diabetes Requiring Medication, Peripheral Vascular Disease, Number of Vessels Diseased and Sum of Risk Factors Squared are interpreted in the same manner as previously described.
Female Gender, Cerebrovascular Disease, Diabetes Requiring Medication and Peripheral Vascular Disease are interpreted in the same manner as CHF, Current in Appendix 1. Number of vessels diseased is comprised of three categories for Appendix 3 (fewer than two vessels diseased, two vessels diseased and three vessels diseased). Two and three vessels diseased refers to patients with at least a 70 percent blockage in two or three of the native coronary arteries including the Left Anterior Descending (LAD), the Right Coronary Artery (RCA) and the Left Circumflex (LCx) or their major branches, respectively. e reference category for this group includes patients who have fewer than two vessels diseased.
e Sum of Risk Factors Squared term is merely the square of the number of risk factors in Appendix 3 that a patient has
(not counting age), and is used to improve the ability of the model to predict mortality.
