Description
肥厚型心肌病(HCM)是年輕人心因性猝死(SCD)的重要因素,也是重要的公共衛生議題。但對於HCM病人SCD的真實機轉,以及預測因子,基因影響,篩檢的效度目前仍不明,本計畫提出由於肌肉纖維的紊亂和纖維化引起的機械電相互作用,因而產生再極化異質性可能是關鍵的病理機轉。因此此計畫第一部分將以通過人工智慧建立心電圖風險評分,以識別學校ECG篩查中識別的HCM中的高風險群體,第二部分將進行心臟核磁共振影像,多層組織都卜勒應變,和血清纖維化標記,以評估心肌的紊亂收縮及與再極化異常和生命威脅事件的關聯。也將進行全外顯子序列分析,並研究遺傳性心律不整基因與小兒科HCM中生命威脅事件的關聯。
