Criteria Used in Reporting Significant Risk Factors (2008) Based on Documentation in Medical Record
Patient Risk Factor
Determined just prior to the intervention.
Patient requires pharmacologic or mechanical support to maintain blood pressure or cardiac output.
Acute hypotension (systolic blood pressure < 80 mmHg) or low cardiac index (< 2.0 liters/min/m2), despite pharmacologic or mechanical support. All cases with this risk factor are excluded from this report.
Congestive Heart Failure (CHF),
Within 2 weeks prior to the procedure, a physician has diagnosed CHF by one of the following:
Paroxysmal nocturnal dyspnea (PND);
Dyspnea on exertion (DOE) due to heart failure; or
Chest X-Ray showing pulmonary congestion.
Malignant Ventricular Arrhythmia
Recent (within the past 14 days) sustained ventricular tachycardia requiring electrical defibrillation or conversion with intravenous antiarrhythmic agents or ventricular fibrillation requiring electrical defibrillation. Excludes V-Tach or V-Fib occurring within 6 hours of the diagnosis of a myocardial infarction and responding well to treatment.
• Renal Failure, Creatinine
Highest Pre-PCI creatinine during the hospital admission was within the indicated range.
• Renal Failure, Dialysis
e patient is on chronic peritoneal or hemodialysis.
• Previous MI
Most recent myocardial infarction (MI) occurred in the specified time period before the intervention.
• ST Elevation
EKG finding of a rise in the S-T interval of >1 mm in two or more contiguous leads.
• Ejection Fraction
Value of the ejection fraction taken closest to the procedure. When a calculated measure is unavailable the ejection fraction should be estimated visually from the ventriculogram or by echocardiography. Intraoperative direct observation of the heart is not an adequate basis for a visual estimate of the ejection fraction.
• Left Main Disease
e patient has at least a 50 percent blockage in the Left Main Coronary Artery.
• Three Vessels Diseased
e patient has at least a 70 percent blockage in each of the three native coronary arteries including the Left Anterior Descending (LAD), the Right Coronary Artery (RCA) and the Left Circumflex (LCx) or their major branches.
