Implication
TIMI and GRACE may aid 1-year mortality prediction in unselected ACS; leaves open optimal score choice pending prospective validation.
Key Points
- To validate five clinical risk scores and develop a novel tool for predicting one-year mortality in unselected patients with acute coronary syndrome.
- Conducted a single-center registry study with one-year follow-up in 931 unselected acute coronary syndrome patients in Poland.
- Evaluated five clinical risk tools (TIMI STEMI, TIMI NSTEMI/UA, GRACE, SIMPLE, and ZWOLLE) and used multivariate logistic regression and receiver-operating characteristic area under the curve (AUC) analysis to develop a new score.
- Identified 12 independent predictors of 1-year mortality, particularly medical history, physical findings at admission, initial ECG, and myocardial necrosis markers.
- Validated all five established risk scores, with TIMI STEMI (AUC = 0.84) and GRACE (AUC = 0.84) displaying superior predictive discrimination.
- Developed the Banach score, which demonstrated high goodness-of-fit and predictive accuracy across all acute coronary syndrome classifications.
Structured PICO
Which risk score best predicts 1-year mortality in unselected patients with acute coronary syndrome?
P
Population
931 unselected patients with acute coronary syndrome (ACS) from a Polish population
I
Intervention
Risk stratification using 5 established risk scores (TIMI STEMI RS, TIMI NSTEMI/UA RS, GRACE RS, SIMPLE RS, ZWOLLE RS) and a newly developed Banach score
O
Outcome
1-year mortality prediction (assessed via area under the curve in receiver-operating characteristic analysis)hard clinical
The TIMI STEMI and GRACE risk scores demonstrated superior predictive value for 1-year mortality in unselected ACS patients, while a newly developed Banach score also showed high predictive value irrespective of ACS type.
