Comparative analysis of the predictive value of short-term risk scales in patients with non-ST-elevation acute coronary syndrome

Objective: to evaluate the prognostic significance, sensitivity, and specificity of the short-term NCDR CathPCI, CADILLAC, ACEF, EuroSCORE II, and SYNTAX risk scales in patients with non-ST-elevation acute coronary syndrome undergoing percutaneous coronary intervention (PCI). Material and methods. The study included 363 patients diagnosed with non-ST-elevation acute coronary syndrome, who underwent primary PCI during hospitalization and a questionnaire based on short-term scales to determine the prognosis of early fatal complications. Results. 28,4% of patients on the ACEF scale, 14,6% on the SYNTAX scale, 13,8% on the CADILLAC scale, 9,9% on the EuroSCORE II scale and only 4.1% on the NCDR-CathPCI scale were classified as high-risk. The CADILLAC (sensitivity: Se=1,000, specificity: Sp=0,907, χ2=118,56; p<0,001) and SYNTAX (Se=1,000, Sp=0,899, χ2=110,78; p<0,001) scales showed maximum sensitivity and high specificity. The ACEF scale showed absolute sensitivity (Se=1,000), but the specificity was 0,754 (χ2=47,81; p<0,001). The EuroSCORE II and NCDR-CathPCI scales showed low sensitivity (Se=0,444 for both scales), but high specificity (EuroSCORE II: Sp=0,919, χ2=25,27; p<0,001, odds ratio: OR=9,06; NCDR-CathPCI: Sp=0,980, χ2=77,69; p<0,001, OR=38,63). Conclusion. The CADILLAC and SYNTAX scales showed the most prognostically significant scales that determine a high prognosis of early fatal complications in patients with – non-STelevation acute coronary syndrome in this study.
