Outline of Final Research Achievements

In our scoping review of the accuracy of serial measurement of high-sensitivity cardiac troponins for diagnosing non-ST-segment elevation acute myocardial infarction revealed that two specific assays dominated the existing evidence and raised a number of methodological concerns. Data on older patients and patients with renal impairment were particularly limited. A network meta-analysis of diagnostic accuracy of the 0/1-hour rapid protocol proposed by the European Society of Cardiology (ESC) showed almost comparable test accuracy with high sensitivity regardless of the assay used. Newer assays may yield more favorable outcomes, yet the evidence still remains insufficient and further validation is warranted. A validation study of the ESC 0/1-hour rapid protocol conducted at our institution yielded comparable results.

Academic Significance and Societal Importance of the Research Achievements

本結果によって、欧州心臓学会が提唱する高感度トロポニン連続法を使用した非ST上昇急性心筋梗塞を診断する迅速プロトコールはアッセイの種類に拠らず、救急外来での安全な疾患除外に貢献し得ることが示唆された。アッセイ間の直接比較は全てのアッセイで十分に実施されておらず、ネットワークメタアナリシスによる直接・間接エビデンスの統合解析によりこれらの包括的な統合評価が可能となった。また、迅速プロトコールはアジアでは十分な検証が実施されていなかったが、アッセイは1種類に限定されるもの、当施設による一次研究のデータは欧州でルチーンで運用されている診断アルゴリズムが本邦でも安全に適応できる可能性を示唆した。
