JAHA:乳头肌异常运动员ECG中T波倒置

2021-01-27 MedSci原创 MedSci原创

PMs肥大和心尖移位可能是运动员无法解释的侧向TWI的基础。PMs异常相关的侧向TWI为独特的临床症状,其特征是患者预后良好。

心脏乳头肌(PMs)异常可能与ECG复极异常有关。近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员旨在评估无临床确诊心脏病的运动员侧向T波倒置(TWI)与PMs特征之间的关系。

研究人员纳入了53名具有侧向TWI的运动员(中位年龄为20岁;男性为87%),他们在临床和心脏磁共振评估中也没有心脏病的证据。心电图正常的健康运动员作为对照组。研究人员评估了PMs的大小,例如直径、面积、体积、质量以及PMs与左心室质量之间的比值,以及PMs心尖移位的患病率。

与对照组相比,TWI运动员表现为PMs肥大,且PMs直径、面积、体积和质量显著增加。TWI运动员的PM与左心室质量之比为4.4%,而对照运动员为3.0%(P<0.001)。PMs/左心室质量比>3.5%用于区分TWI运动员和对照者的敏感性为85%,特异性为76%。在25名(47%)患有TWI的运动员中发现了PM的心尖移位,而9名(17%)对照组中发现了PMs心尖移位(P=0.001)。在多变量分析中,PMs/左心室质量比和心尖移位仍然是TWI的独立预测因子。尽管继续坚持运动,但TWI和PMs异常的运动员的临床结局仍然较为平稳。

由此可见,PMs肥大和心尖移位可能是运动员无法解释的侧向TWI的基础。PMs异常相关的侧向TWI为独特的临床症状,其特征是患者预后良好。
