**ADD POINT(s) TOTAL FOR THE FOLLOWING**
-Systolic Blood Pressure < 80 mm Hg = 5 points
-Intra-aorticl Balloon Pump = 5 points
-Congestive Heart Failure (NYHA Class III-IV and/or pulmonary edema) = 5 points
-Age > 75 years - 4 points

-GFR = 20-40 mL/min/1.73 m2 = 4 points
-GFR < 20 mL/min/1.73 m2 = 6 points
