診断

末期腎不全

患者は、透析中に非特異的な症状を呈しました。ECGでは左室肥大の徴候が示され、冠動脈造影では左回旋枝のらせん状蛇行が認められ、慢性高血圧を伴っていました。冠動脈性心疾患(CHD)の臨床的可能性が高いことを考慮し、慎重に評価する必要がありました。さらに、これらの患者では高感度心筋トロポニンT(cTnT-hs)高値が予想されるため、連続測定が必要です。NACBが発表した推奨事項によると、感度の低いcTn世代(例:第4世代cTnT)の使用において、6~9時間後の再測定で20%超の上昇が見られた場合に急性イベントが示唆されるとしています。22

結論

AMIの診断に必要なcTnT-hs値の上昇または低下はありません。

진단

말기 신부전

환자는 투석하는 동안 비특이적 증상을 경험했습니다. ECG는 좌심실 비대 징후를 보여준 반면, 관상동맥 조영상은 만성 고혈압을 동반한 좌측 회선 동맥에서 코르크 따개 모양의 비틀림을 보여주었습니다. 관상동맥질환(coronary heart disease, CHD)의 임상적 가능성이 높음을 감안하여, 신중한 평가가 필요합니다. 또한 이러한 환자들에서는 cTnT-hs 수치 상승이 예상되기에, 연속 측정이 필요합니다. NACB8이 발표한 권장사항에 따르면, 민감도가 낮은 cTn 세대(예: cTnT 4세대)로 6~9시간 후 반복 측정을 실시하여 20%를 초과하는 증가가 나타나는 경우 급성 AMI를 시사합니다.22

결론

cTnT-hs 값의 상승 또는 하락은 AMI 진단에 있어 필수적인 정보가 아닙니다.

What is the diagnosis of this case?

Diagnosis

End stage renal failure

The patient had experienced non-specific symptoms during dialysis. The ECG showed signs of left ventricular hypertrophy, while the coronary angiogram revealed a corkscrew-like tortuosity of the left circumflex artery accompanied by chronic hypertension. Given the high clinical likelihood of CHD, careful assessment is required. Furthermore, since elevated cTnT-hs levels would be expected in these patients, serial measurements are needed. According to the recommendation published by the NACB8, based on the use of less sensitive cTn generations (e.g. cTnT Gen 4), an increase of more than 20 % for a repeat measurement after 6 – 9 hours is indicative of an acute event.22

Conclusion

There is no rise or fall in cTnT-hs values needed for AMI diagnosis.
