The aim of this systematic review and meta-analysis study was to clarify the effects of sensorineural hearing loss (SNHL) on the incidence of stroke. In line with this, PubMed, Scopus, Web of Science, and ScienceDirect databases were searched using related keywords and MeSH terms from inception to March 1, 2020. Out of the 1961 initial records, eight cohort studies comprising 4,564,202 participants were included, and their qualities were assessed using the Newcastle-Ottawa Scale (NOS). Then, the random-effects model was used to pool HR (95% CI) for risk of stroke; and heterogeneity was presented with I index. Subgroup analysis and publication bias tests were performed, and the pooled HR (95% CI) of stroke in SNHL was estimated as 1.31 (1.08, 1.53) for the unadjusted model and 1.33 (1.18, 1.49) for the adjusted model. Subgroup analysis indicates a significantly higher risk of stroke in patients with sudden SNHL (SSNHL) in comparison to age-related HL (ARHL) both in the unadjusted model, [HR = 1.46; 95% CI (1.08, 1.63)] versus [HR = 1.14; 95% CI (0.64, 1.65)], and in the adjusted model, [HR = 1.44; 95% CI (1.15, 1.74)] versus [HR = 1.29; 95% CI (1.24, 1.34)]. Our study showed that patients with SNHL face a higher risk of stroke than those without SNHL. It is necessary to perform hematologic and neurological examinations to help clinicians detect patients who are potentially at risk for stroke.
本系统评价和荟萃分析的目的是阐明感音神经性听力损失(SNHL)对中风发病的影响。为此,从建库到 2020 年 3 月 1 日,我们使用相关的关键词和 MeSH 术语,在 PubMed、Scopus、Web of Science 和 ScienceDirect 数据库中进行了检索。在 1961 条初始记录中,纳入了 8 项队列研究,共包含 4564202 名参与者,并使用纽卡斯尔-渥太华量表(NOS)评估了这些研究的质量。然后,使用随机效应模型对风险比(95%CI)进行汇总;并用 I 指数表示异质性。进行了亚组分析和发表偏倚检验,并估计了 SNHL 患者的中风合并风险比(95%CI),在未调整模型中为 1.31(1.08,1.53),在调整模型中为 1.33(1.18,1.49)。亚组分析表明,与年龄相关性听力损失(ARHL)相比,突发性 SNHL(SSNHL)患者的中风风险显著更高,在未调整模型中,[风险比(HR)=1.46;95%置信区间(CI)(1.08,1.63)] 与 [HR=1.14;95%CI(0.64,1.65)],在调整模型中,[HR=1.44;95%CI(1.15,1.74)] 与 [HR=1.29;95%CI(1.24,1.34)]。我们的研究表明,SNHL 患者发生中风的风险高于无 SNHL 患者。有必要进行血液学和神经学检查,以帮助临床医生发现有潜在中风风险的患者。
