This was an investigation of the relationship between the N-terminal pro-brain natriuretic peptide (NT-proBNP) level and mortality in patients with stage 3-4 chronic kidney disease (CKD).
This study was designed as a subgroup analysis of the Heart Failure Prevalence and Predictors in Turkey (HAPPY) study. The HAPPY study included 4650 randomly selected individuals from the 7 geographical regions of Turkey. A total of 191 subjects from the original cohort with an estimated glomerular filtration rate (eGFR) <60 mL/min/1.1.73 m² were enrolled in this study and the relationship between NT-proBNP and mortality was investigated. Prognostic variables for total and cardiovascular mortality were also examined using Cox regression analysis.
The mean length of follow-up was 76.12±22.45 months. The mean NT-proBNP level was 423.54±955.88 pg/mL. During follow-up, 51 subjects (26.7%) died from any cause and 36 subjects (18.8%) died from a cardiovascular cause. The presence of hypertension (hazard ratio [HR]: 1.89; 95% confidence interval [CI]: 1.01-3.50; p=0.048), anemia (HR: 2.49; 95% CI: 1.20-5.15; p=0.014), male gender (HR: 2.64; 95% CI: 1.44-4.86; p=0.002) and log NT-proBNP (HR: 4.93; 95% CI: 2.83-8.58; p<0.001) were independent variables for total mortality. The presence of hypertension (HR: 2.47; 95% CI: 1.09-5.56; p=0.029), male gender (HR: 2.79; 95% CI: 1.38-5.62; p=0.004), eGFR (HR: 0.94; 95% CI: 0.91-0.98; p=0.005) and log NT-proBNP (HR: 6.31; 95% CI: 3.11-12.81; p<0.001) were independent predictors of cardiovascular mortality.
NT-proBNP was found to be an independent prognostic marker in patients with stage 3-4 CKD.
本研究旨在探讨3-4期慢性肾脏病（CKD）患者N末端脑钠肽前体（NT-proBNP）水平与死亡率之间的关系。
本研究设计为土耳其心力衰竭患病率及预测因素（HAPPY）研究的亚组分析。HAPPY研究从土耳其7个地理区域随机选取了4650名个体。本研究纳入了原队列中估算肾小球滤过率（eGFR）<60 mL/min/1.73 m²的191名受试者，研究NT-proBNP与死亡率之间的关系。还使用Cox回归分析检查了全因死亡率和心血管死亡率的预后变量。
平均随访时间为76.12±22.45个月。NT-proBNP平均水平为423.54±955.88 pg/mL。随访期间，51名受试者（26.7%）死于任何原因，36名受试者（18.8%）死于心血管原因。高血压（风险比[HR]：1.89；95%置信区间[CI]：1.01-3.50；p=0.048）、贫血（HR：2.49；95%CI：1.20-5.15；p=0.014）、男性（HR：2.64；95%CI：1.44-4.86；p=0.002）和NT-proBNP对数（HR：4.93；95%CI：2.83-8.58；p<0.001）是全因死亡率的独立变量。高血压（HR：2.47；95%CI：1.09-5.56；p=0.029）、男性（HR：2.79；95%CI：1.38-5.62；p=0.004）、eGFR（HR：0.94；95%CI：0.91-0.98；p=0.005）和NT-proBNP对数（HR：6.31；95%CI：3.11-12.81；p<0.001）是心血管死亡率的独立预测因素。
NT-proBNP被发现是3-4期CKD患者的独立预后标志物。
