Abstract:

Background

The Neutrophil percentage to albumin ratio (NPAR) is considered a novel inflammatory marker. Previous studies have confirmed that admission NPAR is an independent predictor of clinical outcomes in various diseases such as sepsis, acute kidney injury, cardiogenic shock, chronic obstructive pulmonary disease, and cerebral hemorrhage.

Objective

The aim of this study is to investigate the potential role of Neutrophil Percentage to Albumin Ratio (NPAR) in predicting the in-hospital adverse events among patients with acute myocardial infarction (AMI).

Methods

This retrospective study included AMI patients (n=6 768) admitted to the People's Hospital of Xinjiang Uygur Autonomous Region from August 1, 2011, to January 10, 2022. Baseline data and laboratory results were collected, and NPAR was calculated. Endpoint events were identified from discharge diagnoses in the electronic medical record system. Patients were divided into quartiles based on NPAR: Q1 (NPAR<1.67, n=1 753), Q2 (1.67≤NPAR≤2.02, n=1 694), Q3 (2.03≤NPAR≤2.34, n=1 624), and Q4 (NPAR>2.34, n=1 697). Multivariate Logistic regression was used to analyze the association between admission NPAR and endpoint events. Restricted cubic spline regression was employed to examine the dose-response relationship between NPAR and endpoint events.

Results

A total of 6 768 patients were included. There were 765 cases (11.3%) of all-cause mortality, 709 cases (10.5%) of cardiogenic shock, 380 cases (5.6%) of ventricular tachycardia/ventricular fibrillation (VT/VF), and 119 cases (1.8%) of new-onset stroke. Multivariate logistic regression analysis with admission NPAR as a continuous variable and all-cause mortality as the dependent variable showed that for each standard deviation increase in NPAR, the risk of all-cause mortality increased by 18% (OR=1.18, 95%CI=1.08-1.29, P<0.001). When NPAR was treated as a categorical variable, the Q4 group (OR=1.48, 95%CI=1.11-1.97, P=0.008) was identified as a risk factor for all-cause mortality, with increasing risk across higher NPAR quartiles (Ptrend=0.007). Restricted cubic spline regression revealed a linear relationship between NPAR and all-cause mortality risk (Pnonlinearity=0.171). Multivariate Logistic regression analysis with cardiogenic shock, VT/VF, atrioventricular block, and new-onset stroke as dependent variables showed that for each standard deviation increase in NPAR, the risk of cardiogenic shock increased by 20% (OR=1.20, 95%CI=1.09-1.32, P<0.001). When NPAR was treated as a categorical variable, the Q2 (OR=1.41, 95%CI=1.01-1.97, P=0.044), Q3 (OR=1.85, 95%CI=1.36-2.54, P<0.001), and Q4 (OR=2.09, 95%CI=1.53-2.89, P<0.001) groups were risk factors for cardiogenic shock, with a trend of increasing risk across higher quartiles (Ptrend<0.001). Restricted cubic spline regression indicated a nonlinear relationship between NPAR and cardiogenic shock risk (Pnonlinearity=0.026). NPAR as a continuous variable was not a risk factor for VT/VF, atrioventricular block (P>0.05). When treated as a categorical variable, Q3 was a risk factor for VT/VF (OR=1.43, 95%CI=1.01-2.03, P=0.045) and atrioventricular block (OR=1.85, 95%CI=1.11-3.15, P=0.020), while Q4 was a risk factor for VT/VF (OR=1.56, 95%CI=1.09-2.26, P=0.017), atrioventricular block (OR=1.87, 95%CI=1.08-3.31, P=0.028), and new-onset stroke (OR=2.26, 95%CI=1.16-4.58, P=0.019). The risks of VT/VF, atrioventricular block, and new-onset stroke increased with higher NPAR quartiles (Ptrend=0.009, 0.005, and 0.017, respectively). Stratified and interaction analyses showed that age, sex, hypertension, type 2 diabetes, smoking, and AMI type did not alter the association between NPAR and in-hospital adverse outcomes (P>0.05).

Conclusion

This study confirms that elevated NPAR is associated with an increased risk of in-hospital all-cause mortality and cardiogenic shock in AMI patients, exhibiting a dose-response relationship. These findings suggest that NPAR, as a simple and accessible composite marker of inflammation and nutritional status, may help identify high-risk patients early during admission and provide valuable reference for clinical risk stratification and prognostic assessment.

摘要:

背景

中性粒细胞百分比/白蛋白比值(NPAR)被认为是一种新的炎症标志物,既往研究证实入院NPAR是许多疾病,如脓毒症、急性肾损伤、心源性休克、慢性阻塞性肺疾病和脑出血临床结局的独立预测因子。

目的

探讨入院时NPAR与急性心肌梗死(AMI)患者住院期间不良事件之间的关联。

方法

回顾性纳入2011-08-01—2022-01-10在新疆维吾尔自治区人民医院就诊并住院的6 768例AMI患者,收集患者基线资料和实验室检查结果,计算NPAR,通过电子病历系统中的出院诊断获取患者终点事件。依据NPAR四分位数将患者分为Q1(NPAR<1.67,n=1 753)、Q2(1.67≤NPAR≤2.02,n=1 694)、Q3(2.03≤NPAR≤2.34,n=1 624)与Q4组(NPAR>2.34,n=1 697)。采用多因素Logistic回归分析探讨入院NPAR与患者终点事件发生的相关性,使用限制性立方样条回归曲线分析NPAR与终点事件的剂量-反应关系。

结果

最终纳入研究对象6 768例,全因死亡765例(11.3%),心源性休克709例(10.5%),室性心动过速(VT)/心室颤动(VF)380例(5.6%),新发脑卒中119例(1.8%)。分别以入院NPAR和NPAR分组为自变量,以患者全因死亡为因变量进行多因素Logistic分析,结果显示NPAR每升高1个标准差,患者全因死亡风险增加18%(OR=1.18,95%CI=1.08~1.29,P<0.001);当NPAR作为分类变量时,Q4组(OR=1.48,95%CI=1.11~1.97,P=0.008)是患者全因死亡的危险因素,随着NPAR分组升高患者死亡风险增加(P趋势=0.007);限制性立方样条回归曲线结果显示NPAR与全因死亡风险呈线性相关(P非线性=0.171)。分别以心源性休克、VT/VF、房室传导阻滞、新发脑卒中为因变量进行多因素Logistic回归分析,结果显示NPAR每升高1个标准差患者心源性休克风险增加20%(OR=1.20,95%CI=1.09~1.32,P<0.001);NPAR作为分类变量时,Q2组(OR=1.41,95%CI=1.01~1.97,P=0.044)、Q3组(OR=1.85,95%CI=1.36~2.54,P<0.001)、Q4组(OR=2.09,95%CI=1.53~2.89,P<0.001)是患者心源性休克的危险因素,随着NPAR分组升高患者心源性休克风险增加(P趋势<0.001);限制性立方样条回归曲线结果显示NPAR与心源性休克风险非线性相关(P非线性=0.026)。NPAR作为连续变量不是VT或VF、房室传导阻滞的危险因素(P>0.05);NPAR作为分类变量时,Q3是VT或VF(OR=1.43,95%CI=1.01~2.03,P=0.045)、房室传导阻滞(OR=1.85,95%CI=1.11~3.15,P=0.020)的危险因素;Q4组是VT或VF(OR=1.56,95%CI=1.09~2.26,P=0.017)、房室传导阻滞(OR=1.87,95%CI=1.08~3.31,P=0.028)、新发脑卒中(OR=2.26,95%CI=1.16~4.58,P=0.019)的危险因素;随着NPAR分组升高患者VT或VF、房室传导阻滞、新发脑卒中风险增加(P趋势=0.009、0.005、0.017)。分层分析和交互作用分析结果显示,年龄、性别、高血压、2型糖尿病、吸烟和急性心肌梗死分型均未改变NPAR与住院不良结局风险之间的关系(P>0.05)。

结论

本研究结果证实,NPAR升高与AMI患者住院期间全因死亡和心源性休克的风险有关,并呈现剂量-反应关系。提示NPAR作为一种简便、可得的炎症及营养状态复合指标,能够在入院早期帮助识别高危患者,为临床风险分层和预后评估提供有价值的参考。
