JACC:血清电解质浓度与心电图改变呈相关性

2019-06-26 不详 MedSci原创

心电图的亚临床改变是心血管死亡的风险因素,目前对心脏电生理学中电解质相关性的认识仅基于严重疾病患者的体外模型和观察。本研究的目的旨在评估血清电解质浓度与心电图改变的相关性。本次荟萃分析纳入了来自33个临床研究中的153014名研究对象(女性占54.4%,平均年龄55.1±12.1岁 ),并对研究对象的电解质浓度(钙、钾、钠、镁)和心电图的间期(RR、QT、QRS、JT和PR)相关性进行了线性回归分

心电图的亚临床改变是心血管死亡的风险因素,目前对心脏电生理学中电解质相关性的认识仅基于严重疾病患者的体外模型和观察。本研究的目的旨在评估血清电解质浓度与心电图改变的相关性。

本次荟萃分析纳入了来自33个临床研究中的153014名研究对象(女性占54.4%,平均年龄55.1±12.1岁 ),并对研究对象的电解质浓度(钙、钾、钠、镁)和心电图的间期(RR、QT、QRS、JT和PR)相关性进行了线性回归分析。分析结果显示,更低的血清钙离子浓度与更长的QT和JT间期相关,相比之下,更高的镁离子浓度与更长的QT和JT间期相关,低钾离子浓度与更长的QT间期、QRS和PR时长相关,但所有与钾离子相关的结果均与抗高血压药物的服用有关。另外,钠离子与RR间期的相关性未观察到。

研究结果显示,血清电解质浓度确实与心电图的改变呈相关性。
