    摘要:

    目的 观察长链非编码RNA预测心脏重构(LIPCAR)在慢性心力衰竭及合并肾功能不全患者循环中的表达。方法 收集80例健康对照者、188例慢性心力衰竭患者,其中合并肾功能不全患者80例,用实时荧光定量PCR检测患者循环中的LIPCAR。结果 LIPCAR的表达水平在健康对照组与慢性心力衰竭组之间有显著差异(1.08±0.28比0.79±0.31,P<0.01)。对慢性心力衰竭组进行亚组分析发现,LIPCAR在慢性心力衰竭合并肾功能不全患者中表达有进一步降低趋势。此外,LIPCAR与NT-proBNP呈负相关,与射血分数(EF)呈正相关(P<0.01)。LIPCAR在判断心力衰竭时,AUC为0.777(95%CI为0.720~0.835)。结论 LIPCAR在慢性心力衰竭及合并肾功能不全患者循环中表达均降低,可作为诊断慢性心力衰竭的潜在生物学标志物。

    Abstract:

    Aim To explore the circulating levels of long intergenic non-coding RNA predicting cardiac remodeling (LIPCAR) in patients with chronic heart failure (CHF) and combined renal insufficiency. Methods Venous blood samples were collected from 80 control subjects, 188 patients with CHF, including 80 patients with renal insufficiency, LIPCAR was evaluated by real-time PCR. Results The expression of LIPCAR was significantly different between the control group and the CHF group (1.08±0.28 vs.0.79±0.31, P<0.01). In addition, the subgroup analysis of CHF showed that the patients complicated with renal insufficiency exhibited a tendency of lower levels of LIPCAR. Furthermore, LIPCAR was negatively correlated with NT-proBNP, whereas positively correlated with ejection fraction (P<0.01). AUC was 0.777(95%CI=0.720~0.835) for LIPCAR to judge CHF. Conclusion Circulating LIPCAR levels were significantly downregulated in patients with CHF, especially in those complicated with renal insufficiency. It may be valuable as a potential biomarker for CHF.
