摘要:

目的 探讨血清正五聚蛋白3(PTX3)水平与心力衰竭(HF)患者心功能分级和心脏储备功能的相关性。方法 选取2020年6月—2023年6月邯郸市第一医院HF患者220例、非HF患者110例(对照组)。按纽约心脏病学会(NYHA)心功能分级标准将HF患者分为NYHA Ⅰ级组(67例)、NYHA Ⅱ级组(68例)、NYHA Ⅲ级组(51例)、NYHA Ⅳ级组(34例)。收集所有患者的临床资料,并检测心脏储备功能指标和血清PTX3水平。采用多因素Logistic回归分析评估HF病情严重程度的影响因素。采用分层交互分析PTX3水平与HF心功能分级的关系。采用多元线性回归分析评估血清PTX3水平与心脏储备功能指标的相关性。采用限制性立方样条法分析血清PTX3与HF严重程度的剂量反应关系。采用中介效应模型分析心脏储备功能对PTX3和HF严重程度的中介效应。对所有患者进行为期1年的随访,采用Kaplan-Meier生存曲线分析HF患者的生存情况。结果 对照组、NYHA Ⅰ级组、NYHA Ⅱ级组、NYHA Ⅲ级组、NYHA Ⅳ级组之间年龄、体重指数、糖尿病史、冠心病史、瓣膜病史、高血压史、收缩压、舒张压、舒张期时限(D)/收缩期时限(S)比值、左心室射血分数(LVEF)、心脏指数(CI)、心输出量(CO)、第一心音幅值(S1)/第二心音幅值(S2)比值、B型钠尿肽(BNP)、PTX3差异均有统计学意义(P<0.05)。年龄较大、有糖尿病史、有冠心病史、有瓣膜病史、心率降低、收缩压降低、舒张压降低、D/S比值降低、LVEF降低、CI降低、CO降低、S1/S2比值升高、PTX3升高、BNP升高均是HF患者为NYHAⅢ~Ⅳ级的危险因素(P<0.05)。心率≤90 次·min-1、收缩压≤18.67 kPa、舒张压≤12.00 kPa、S1/S2比值>3.50、D/S比值≤1.30、LVEF≤48.21%、CI≤2.11 L·min-1·m-2、CO≤3.49 L·min-1、BNP>946.35 pg·mL-1的患者血清PTX3水平与HF心功能分级加重的关系稳定存在(P<0.05)。心率、收缩压、舒张压、D/S比值、LVEF、CI、CO降低和S1/S2比值升高均是血清PTX3水平升高的独立影响因素(P<0.05)。血清PTX3水平连续变化与HF加重的关联强度呈非线性剂量反应关系(P<0.05)。心率、收缩压、舒张压、S1/S2比值、D/S比值、LVEF、CI、CO均在PTX3和HF严重程度之间发挥中介效应。NYHAⅠ级组、NYHA Ⅱ级组、NYHA Ⅲ级组、NYHA Ⅳ级组1年累积生存率分别为83.58%、75.00%、54.90%、32.35%;各组间生存率差异有统计学意义(Log-rank χ2=38.641,P<0.001);PTX3低水平组1年累积生存率(80.91%)高于高水平组(51.82%)(Log-rank χ2=24.173,P<0.001)。结论 血清PTX3是HF患者心功能分级的独立影响因素,心脏储备功能在PTX3和心功能分级之间发挥中介效应。血清PTX3或可作为HF患者病情评估的有效指标。

Abstract:

Objective To investigate the correlation between serum pentraxin 3(PTX3) levels and the cardiac function classification,cardiac reserve function of patients with heart failure(HF). Methods A total of 220 HF patients and 110 non-HF patients(control group) from the First Hospital of Handan City from June 2020 to June 2023 were enrolled. According to the New York Heart Association(NYHA) cardiac function classification standard,the HF patients were classified into NYHA grade Ⅰ group(67 cases),NYHA grade Ⅱ group(68 cases),NYHA grade Ⅲ group(51 cases) and NYHA grade Ⅳ group(34 cases). The clinical data were collected,and the cardiac reserve function indicators and serum PTX3 levels were determined. Multivariate Logistic regression analysis was used to evaluate the influencing factors of the severity of HF. Stratified interaction analysis was used to analyze the relationship between PTX3 levels and the aggravation of HF cardiac function classification. Multivariate linear regression analysis was used to evaluate the correlation between serum PTX3 levels and cardiac reserve function indicators. Restricted cubic spline method was used to analyze the dose-response relationship between serum PTX3 and the severity of HF. The mediation effect model was used to analyze the mediating effect of cardiac reserve function on PTX3 and the severity of HF. All the patients were followed up for 1 year. Kaplan-Meier survival curve was used to analyze the survival situation of HF. Results There was statistical significance in age,body mass index,history of diabetes,history of coronary heart disease,history of valvular disease,history of hypertension,systolic blood pressure,diastolic blood pressure,diastolic duration(D)/systolic duration(S) ratio,left ventricular ejection fraction(LVEF),cardiac index(CI),cardiac output(CO),the first heart sound(S1)/the second heart sound(S2) ratio,B-type natriuretic peptide(BNP) and PTX3 among control group,NYHA grade Ⅰ group,NYHA grade Ⅱ group,NYHA grade Ⅲ group and NYHA grade Ⅳ group(P<0.05). Elder,history of diabetes,history of coronary heart disease,history of valvular disease,decreased heart rate,decreased systolic blood pressure,decreased diastolic blood pressure,decreased D/S ratio,decreased LVEF,decreased CI,decreased CO,increased S1/S2 ratio,increased BNP and increased PTX3 were all risk factors for HF NYHA grade Ⅲ-Ⅳ patients(P<0.05). Patients with heart rate ≤90 times·min-1,systolic blood pressure ≤18.67 kPa,diastolic blood pressure ≤12.00 kPa,S1/S2 ratio>3.50,D/S ratio≤1.30,LVEF≤48.21%,CI≤2.11 L·min-1·m-2,CO≤3.49 L·min-1 and BNP>946.35 pg·mL-1 had a stable relationship between serum PTX3 levels and the aggravation of HF cardiac function classification(P<0.05). Decreased heart rate,systolic blood pressure,diastolic blood pressure,D/S ratio,LVEF,CI,CO and increased S1/S2 ratio were independent influencing factors for the increase in serum PTX3 levels(P<0.05). The association strength between the continuous change of serum PTX3 levels and the aggravation of HF showed a non-linear dose-response relationship(P<0.05). Cardiac reserve function,including heart rate,systolic blood pressure,diastolic blood pressure,D/S ratio,LVEF,CI and CO,all played mediating effects between PTX3 and the severity of HF. The 1-year cumulative survival rates of the NYHA grade Ⅰ group,NYHA grade Ⅱ group,NYHA grade Ⅲ group and NYHA grade Ⅳ group were 83.58%,75.00%,54.90% and 32.35%,respectively. The differences in survival rates among the groups were statistically significant(Log-rank χ2=38.641,P<0.001). The 1-year cumulative survival rate of low PTX3 level group(80.91%) was higher than that of high PTX3 level group(51.82%)(Log-rank χ2=24.173,P<0.001). Conclusions Serum PTX3 is an independent influencing factor for the cardiac function classification in patients with HF,and cardiac reserve function plays a mediating role. Serum PTX3 may serve as an effective indicator for the assessment of the condition of patients with HF.
