The new score predicts 1-year poor outcome in patients with successful percutaneous coronary intervention: Naples prognostic score

Abstract

Aims: This study investigated the relationship between Naples prognostic score (NPS) and 1-year poor clinical outcomes in patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI).
 Methods: The study included 121 patients who had NSTEMI and received successful PCI treatment. The researchers calculated NPS using the neutrophil/lymphocyte ratio, lymphocyte/monocyte ratio, serum albumin level, and total cholesterol. The patients were divided into two groups based on their NPS scores: those with scores of 0.1 and 2 and those with scores of 3 and 4. The study compared the occurrence of major cardiovascular events (MACE) such as 1-year all-cause mortality, 1-year nonfatal recurrent MI, and stroke between the two groups.
 Results: Patients with high NPS scores were observed to have significantly higher all-cause mortality than those with low NPS scores (23.9% vs. 9.3%, p=0.029). When the MACEs of the patients were compared, significantly higher MACE was observed in the high NPS group (39.1% vs. 18.7%, p=0.013).
 In multivariate logistic regression analysis, creatinine (OR:4,914, CI 95%: 1.310-18,433, p=0.018) and NPS 3-4 (OR:2.565, CI 95%: 1.093-6.017, p=0.030) were independent predictors of MACE.
 Conclusion: Composite MACEs of non-fatal recurrent MI, cerebrovascular accident, and all-cause death were higher at one year in patients with high NPS who underwent successful percutaneous intervention. High NPS is an indicator of MACE.
