Angeli et al reported a risk score for predicting 1-year mortality following a non-ST segment elevation acute coronary syndrome in an adult >= 75 years of age. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple hospitals in Italy.
Patient selection: non-ST segment elevation ACS in adult >= 75 years of age
Outcome: 1-year mortality
Parameter:
(1) hemoglobin in g/dL
(2) serum troponin concentration
(3) ischemic changes in ECG
(4) eGFR in mL per minute per 1.73 square meter
(5) history of previous vascular event

Interpretation:
• minimum score: 0
• maximum score: 6
• The higher the score the greater the 1-year mortality.
