Fu et al reported a simple score for predicting in-hospital mortality for a patient with acute myocardial infarction (AMI) and end-stage renal disease (ESRD). The authors are from Capital Medical University in Beijing.
Patient selection: hospitalized patient with acute myocardial infarction and end-stage renal disease
Parameters:
(1) age in years
(2) heart rate on admission in beats per minute
(3) left ventricular ejection fraction (LVEF) in percent
(4) serum CRP in mg/L
(5) D-dimer in mg/L FEU

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 8
• Patients who died had a mean score of 6.6 +/- 1.7, versus 3.5 +/- 1.6 for those who survied.
• This roughly means that a score >= 6 is high risk with mortality; a score <= 3 is low risk; a score of 4 or 5 is intermediate risk.
Performance:
• The area under the ROC curve is 0.90.
