Platelet-to-lymphocyte ratio (PLR) is an inflammation index suggested to have the prognostic capability in heart failure (HF). We sought to investigate the association of PLR with cardiovascular disease (CVD) mortality and creatinine (Cr) rise among Iranian individuals suffering from acute decompensated HF (ADHF). This retrospective cohort study was in the context of the Persian Registry Of cardioVascular diseasE/Heart Failure (PROVE/HF) study. 405 individuals with ADHF admitted to the emergency department were recruited from April 2019 to March 2020. PLR was calculated by division of platelet to absolute lymphocyte counts and categorized based on quartiles. We utilized the Kaplan–Meier curve to show the difference in mortality based on PLR quartiles. Cr rise was defined as the increment of at least 0.3 mg/dl from baseline. Cox proportional hazard ratio (HR) was used to investigate the association of PLR with CVDs mortality. Mean age of participants was 65.9 ± 13.49 years (males: 67.7%). The mean follow-up duration was 4.26 ± 2.2 months. CVDs mortality or re-hospitalization was not significantly associated with PLR status. Multivariate analysis of PLR quartiles showed a minimally reduced likelihood of CVDs death in 2nd quartile versus the first one (HR 0.40, 95% confidence interval (CI) 0.16–1.01, P = 0.054). Cr rise had no remarkable relation with PLR status in neither model. PLR could not be used as an independent prognostic factor among ADHF patients. Several studies are required clarifying the exact utility of this index.

急性失代偿性心力衰竭患者血小板与淋巴细胞比率与死亡率的关系

血小板与淋巴细胞比率 (PLR) 是一种炎症指数,被认为对心力衰竭 (HF) 具有预后能力。我们试图在患有急性失代偿性心力衰竭 (ADHF) 的伊朗人中调查 PLR 与心血管疾病 (CVD) 死亡率和肌酐 (Cr) 升高的关系。这项回顾性队列研究是在波斯心血管疾病登记处/心力衰竭 (PROVE/HF) 研究的背景下进行的。从 2019 年 4 月至 2020 年 3 月,招募了 405 名急诊科收治的 ADHF 患者。PLR 是通过将血小板除以绝对淋巴细胞计数来计算的,并根据四分位数进行分类。我们利用 Kaplan-Meier 曲线显示基于 PLR 四分位数的死亡率差异。Cr 升高定义为从基线增加至少 0.3 mg/dl。Cox 比例风险比 (HR) 用于研究 PLR 与 CVDs 死亡率的关系。参与者的平均年龄为 65.9 ± 13.49 岁(男性:67.7%)。平均随访时间为 4.26 ± 2.2 个月。CVD死亡率或再次住院与PLR状态无显着相关性。PLR 四分位数的多变量分析显示,与第一个四分位数相比,第二个四分位数的 CVD 死亡可能性最小(HR 0.40,95% 置信区间 (CI) 0.16-1.01,P = 0.054)。在这两种模型中,Cr 上升与 PLR 状态没有显着关系。PLR 不能用作 ADHF 患者的独立预后因素。需要进行几项研究来阐明该指数的确切效用。平均随访时间为 4.26 ± 2.2 个月。CVD死亡率或再次住院与PLR状态无显着相关性。PLR 四分位数的多变量分析显示,与第一个四分位数相比,第二个四分位数的 CVD 死亡可能性最小(HR 0.40,95% 置信区间 (CI) 0.16-1.01,P = 0.054)。在这两种模型中,Cr 上升与 PLR 状态没有显着关系。PLR 不能用作 ADHF 患者的独立预后因素。需要进行几项研究来阐明该指数的确切效用。平均随访时间为 4.26 ± 2.2 个月。CVD死亡率或再次住院与PLR状态无显着相关性。PLR 四分位数的多变量分析显示,与第一个四分位数相比,第二个四分位数的 CVD 死亡可能性最小(HR 0.40,95% 置信区间 (CI) 0.16-1.01,P = 0.054)。在这两种模型中,Cr 上升与 PLR 状态没有显着关系。PLR 不能用作 ADHF 患者的独立预后因素。需要进行几项研究来阐明该指数的确切效用。01,P = 0.054)。在这两种模型中,Cr 上升与 PLR 状态没有显着关系。PLR 不能用作 ADHF 患者的独立预后因素。需要进行几项研究来阐明该指数的确切效用。01,P = 0.054)。在这两种模型中,Cr 上升与 PLR 状态没有显着关系。PLR 不能用作 ADHF 患者的独立预后因素。需要进行几项研究来阐明该指数的确切效用。
