Background

Recent cohort studies evaluated the association between some previously identified high-risk ceramides [Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/22:0), Cer(d18:1/24:0) and Cer(d18:1/24:1)] and risk of major adverse cardiovascular events in adult population.

Objective

The objective of this meta-analysis was to investigate the magnitude of such associations.

Methods

We searched publication databases using appropriate keywords to identify cohort studies (published up to July 30, 2019), in which association between previously identified high-risk ceramides and major adverse cardiovascular events was reported. Data from eligible studies were extracted and meta-analysis was performed using random-effects modeling.

Results

Seven cohort studies with aggregate data on 29,818 individuals (2736 new cases of cardiovascular events over a median follow-up of 6 years) were included. Higher plasma levels of Cer(d18:1/16:0) (random effects hazard ratio [HR] per standard deviation 1.21, 95% confidence interval [CI] 1.11–1.32, I2 = 88%), Cer(d18:1/18:0) (HR 1.19, 95% CI 1.10–1.27, I2 = 68%), and Cer(d18:1/24:1) (HR 1.17, 95% CI 1.08–1.27, I2 = 83%) were associated with major adverse cardiovascular events. Conversely, no association with plasma levels of Cer(d18:1/22:0) (HR 1.14 95% CI 0.88–1.47, I2 = 88%) and Cer(d18:1/24:0) (HR 0.97, 95% CI 0.89–1.05, I2 = 73%) was found. Subgroup analyses did not substantially modify the findings.

Conclusions

Higher plasma levels of Cer(d18:1/16:0), Cer(d18:1/18:0) and Cer(d18:1/24:1) were associated with major adverse cardiovascular events, whereas plasma levels of Cer(d18:1/22:0) and Cer(d18:1/24:0) were not. Additional research is required to elucidate the different role of ceramides on pathways involved in cardiovascular disease.

神经酰胺和重大心血管不良事件的风险:纵向研究的荟萃分析。

背景

最近的队列研究评估了一些先前确定的高风险神经酰胺[Cer(d18:1/16:0),Cer(d18:1/18:0),Cer(d18:1/22:0),Cer( d18:1/24:0)和Cer(d18:1/24:1)]和成人人群发生重大不良心血管事件的风险。

目的

荟萃分析的目的是调查这种关联的程度。

方法

我们使用适当的关键字搜索了出版物数据库,以识别队列研究(截至2019年7月30日发布),其中报道了先前确定的高风险神经酰胺与重大不良心血管事件之间的关联。从符合条件的研究中提取数据,并使用随机效应模型进行荟萃分析。

结果

纳入了七项队列研究,收集了29,818名个体的汇总数据(中位随访期为6年,共2736例新的心血管事件)。较高的Cer(d18:1/16:0)血浆水平(每个标准差的随机效应危险比[HR] 1.21,95%置信区间[CI] 1.11–1.32,I 2  = 88%),Cer(d18:1 / 18:0)(HR 1.19,95%CI 1.10–1.27,I 2  = 68%)和Cer(d18:1/24:1)(HR 1.17,95%CI 1.08–1.27,I 2  = 83% )与重大不良心血管事件相关。相反,血浆Cer(d18:1/22:0)(HR 1.14 95%CI 0.88–1.47,I 2  = 88%)和Cer(d18:1/24:0)(HR 0.97,95 ) %CI 0.89–1.05,I 2  = 73%)。亚组分析并没有实质性改变研究结果。

结论

较高的Cer(d18:1/16:0),Cer(d18:1/18:0)和Cer(d18:1/24:1)血浆水平与主要不良心血管事件相关,而血浆Cer( d18:1/22:0)和Cer(d18:1/24:0)不是。需要进一步的研究来阐明神经酰胺在心血管疾病相关途径中的不同作用。
