Goriki et al reported a model for predicting in-hospital mortality for a patient with an ST-segment elevation myocardial infarction (STEMI). This can help to identify a patient who may require more aggressive management. The authors are from Miyazaki Medical Association Hospital Cardiovascular Center and Sage University in Japan.
Patient selection: in-hospital with ST-segment elevated myocardial infarction (STEMI)
Parameters:
(1) platelet count per microliter
(2) blood glucose in mg/dL
(3) eGFR in mL per min per 1.73 square meter
(4) serum albumin in g/dL
(5) high-sensitivity serum troponin I in ng/dL

where:
• The cutoff for troponin I was at 50 times the upper limit of normal.

Interpretation:
• minimum score: 0
• maximum score: 8
