Introduction: Hospitalization mortality in ST-elevation Myocardial Infarction (STEMI) patients are
affected by several factors, including initial identification of the risks at hospital admission. Risk
score tools as a predictor of STEMI complication and death event in STEMI patients is a simple risk
index score. The aim of this study was to determine the association between simple risk index score
and hospitalization mortality in STEMI patients.
Methods: We retrospectively enrolled 60 consecutive patients who were admitted to our hospital
diagnosed with STEMI. The simple risk index score was calculated for each patient using equation:
heart rate x [age/10]2/systolic blood pressure. The patients were assigned into 2 groups according to
this score, high score and low score group. Incidence of death during hospitalization in STEMI
patients was recorded.
Results: The total subjects were 60 people. The subjects consisted of 30 patients with low score and
30 subjects with high score. The incidence of death during hospitalization in the group of high simple
risk index score were 26 patients, and in the group of low simple risk index score were 13 patients.
The association between the simple risk index score and the deaths during hospitalization in STEMI
patients based on statistical analysis was significant (p= 0.00) and value of risk relative (RR) is 2.167;
95% CI: 1.368-3.433; (p=0.000).
Conclusion: Simple risk index score is associated with hospitalization mortality in ST-elevation
myocardial Infarction (STEMI) patients.
