Outline of Research at the Start

本研究では、ブルガダ症候群と不整脈源性右室心筋症の同異性を臨床的および分子生物学的に検討しoverlap群の存在とその病態を明確にすること、典型的な脱分極異常モデルの不整脈源性右室心筋症とブルガダ症候群との相違性の検討によって両疾患における特徴的な心電図や致死的不整脈の発生機序を解明し、さらに一次予防としての適切な治療法を確立することを目的とする。

Outline of Final Research Achievements

This research found that the prevalence of the Brugada ECG pattern was quite low despite a long-term follow-up period and repeated ECG with upper intercostal recordings in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). The appearance of the Brugada ECG pattern was transient. The Brugada ECG pattern in ARVC patients was associated with a longer PQ interval, longer QRS duration, and cardiac events, including cardiac death and HF hospitalization. Unfortunately, genetic analysis was not performed in all ARVC patients with Brugada ECG pattern. Accordingly, the relationship between genetic mutation and Brugada type ECG in ARVC patients could not be evaluated. Further prospective, multicenter studies, which include a larger number of ARVC patients, are warranted to confirm these findings. However, at this point, the hypothesis that Brugada syndrome is an early stage of ARVC seems negative.

Academic Significance and Societal Importance of the Research Achievements

ブルガダ症候群患者は不整脈源性右室心筋症(ARVC)患者の初期段階であるという仮説があるが、本研究結果からはそれは否定的で、むしろかなり進行したARVC患者において一過性にブルガダ型心電図が出現する傾向を認めた。またその心電図波形も一般的な症候性ブルガダ症候群と比べて非典型的であった。ブルガダ症候群とARVCは類似した所見も認めるが基本的に異なる疾患であることが示唆された。
