Abstract:

Background

Coronary artery calcification (CAC) is one of the most important pathological features of coronary atherosclerosis and is prevalent among patients with coronary heart disease (CHD). Early identification of CHD patients at risk for CAC is of great clinical significance.

Objective

To investigate the correlation between neutrophil percentage-to-albumin ratio (NPAR) levels and CAC in patients with CHD based on optical coherence tomography (OCT).

Methods

A total of 430 CHD patients who underwent percutaneous coronary intervention (PCI) in the Department of Cardiology at Fuwai Central China Cardiovascular Hospital between January 2022 and August 2023 were included. Clinical data were extracted via the hospital's electronic medical record system. Based on coronary angiography and OCT results, patients were divided into a CAC group (n=212) and a non-CAC group (n=218). Multivariate Logistic regression analysis was used to explore the effect of different NPAR levels and every 1 standard deviation (SD) increase in NPAR on CAC in CHD patients. Subgroup analyses and interaction tests were performed according to age, sex, BMI, and smoking history.

Results

The mean age of the included patients was (61.3±11.3) years. The CAC group had higher levels of age, diabetes, hypertension, white blood cell count, neutrophil count, neutrophil percentage, total cholesterol, fasting blood glucose, and NPAR compared to the non-CAC group. Conversely, the CAC group had lower levels of lymphocyte count, total protein, and albumin (P<0.05). Patients were divided into three groups according to NPAR tertiles: T1 group (NPAR<1.42, n=144), T2 group (1.42≤NPAR<1.63, n=143), and T3 group (NPAR≥1.63, n=143). Significant differences were observed among the three groups regarding the proportions of cholesterol crystals, macrophage infiltration, thrombosis, and plaque erosion (P<0.05). Multivariate Logistic regression results showed that for every 1 SD increase in NPAR, the risk of CAC increased by 1.760 times (OR=2.760, 95%CI=1.842-4.135, P<0.001). The risk of CAC increased progressively from the T1 to T3 groups (Ptrend<0.001). The risk of CAC in the T2 and T3 groups was 3.818 times (OR=3.818, 95%CI=2.211-6.594, P<0.001) and 8.585 times (OR=8.585, 95%CI=4.430-16.637, P<0.001) that of the T1 group, respectively. Subgroup analysis suggested that elevated NPAR was a risk factor for CAC across different age, sex, BMI, and smoking status subgroups (P<0.05). However, the multiplicative interaction effects between NPAR and age, sex, BMI, or smoking history were not statistically significant (Pinteraction>0.05).

Conclusion

Elevated NPAR levels are significantly and independently associated with an increased risk of CAC in CHD patients, suggesting its potential role as a biomarker reflecting the inflammatory pathological processes underlying CAC.

摘要:

背景

冠状动脉钙化(CAC)病变是冠状动脉粥样硬化的重要病理特征之一,在冠心病患者中普遍存在,早期识别存在CAC风险的冠心病患者具有非常重要的临床意义。

目的

基于光学相干断层扫描(OCT)探讨冠心病患者血清中性粒细胞百分比与白蛋白比值(NPAR)水平与CAC的相关性。

方法

回顾性纳入2022年1月—2023年8月于阜外华中心血管病医院心内科行经皮冠状动脉介入治疗(PCI)的冠心病患者430例,通过医院电子病历系统提取患者临床数据,并依据冠状动脉造影和OCT检查结果,根据有无CAC将患者分为CAC组(212例)和非CAC组(218例)。采用多因素Logistic回归分析探讨不同NPAR水平分组及NPAR每增加1个标准差(SD)对冠心病患者CAC的影响,并按年龄、性别、BMI、吸烟史进行亚组分析与交互作用检验。

结果

纳入患者平均年龄(61.3±11.3)岁。CAC组患者年龄、糖尿病、高血压、白细胞计数、中性粒细胞计数、中性粒细胞百分比、总胆固醇、空腹血糖及NPAR高于非CAC组,淋巴细胞计数、总蛋白、白蛋白低于非CAC组(P<0.05)。将患者按照NPAR三分位数分为T1组(NPAR<1.42,n=144)、T2组(1.42≤NPAR<1.63,n=143)、T3组(NPAR≥1.63,n=143),三组患者胆固醇结晶、巨噬细胞浸润、血栓形成、斑块侵蚀比例比较,差异有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,NPAR每增加1个SD,CAC发生风险增加1.760倍(OR=2.760,95%CI=1.842~4.135,P<0.001);T1~T3组CAC发生风险依次升高(P趋势<0.001),T2、T3组CAC发生风险分别为T1组的3.818倍(OR=3.818,95%CI=2.211~6.594,P<0.001)、8.585倍(OR=8.585,95%CI=4.430~16.637,P<0.001)。亚组分析结果显示,在不同年龄、性别、BMI、吸烟情况患者中,NPAR升高均为CAC发生的危险因素(P<0.05),NPAR与年龄、性别、BMI、吸烟的交互作用无统计学意义(P交互>0.05)。

结论

NPAR水平升高与冠心病患者CAC发生风险显著且独立相关,提示其可能作为反映CAC炎症病理过程的潜在生物学标志物。
