급성 심근 경색 시험 후 생존 가능성 유도 혈관 성형술 (VIAMI 시험)
급성 심근경색 후 조기에 경색 부위 생존이 가능한 환자에서 경색 관련 동맥 선택적 스텐트 시술의 조기 및 장기 결과 VIAMI-시험.
연구 개요
상세 설명
이전 연구에서는 급성 심근경색에 대한 혈전용해술 직후 경색 관련 관상동맥의 일상적인 혈관성형술이 임상적 이점을 가져오지 못한 것으로 나타났습니다. 이 발견은 경색 관련 동맥의 혈관성형술이 실제로 도움이 될 최근 심근경색 환자의 하위 그룹을 선택하는 것이 중요함을 강조합니다.
여러 연구에서 급성 심근경색 후 조기에 경색 부위에 생존 가능성이 있으면 재발성 경색, 협심증 및 관상동맥 중재술의 필요성과 같은 새로운 심장 사건의 위험이 증가한다는 것이 입증되었습니다. 따라서 경색 부위에 생존 능력이 있는 환자만이 급성 심근 경색 후 조기에 혈관성형술로 혜택을 볼 수 있다고 가정합니다.
VIAMI 임상시험에서 급성 심근경색으로 병원에 입원하고 즉각적인 관상동맥 성형술을 받지 않은 환자는 입원 3일 이내에 도부타민-심초음파로 생존력 검사를 받게 된다. 경색 영역에서 명백한 생존 징후가 있는 환자는 침습적 또는 보존적 치료 전략에 무작위 배정됩니다. 침습적 전략에서 환자는 정맥 내 혈소판 억제제 abciximab의 동시 사용과 함께 경색 관련 관상 동맥의 스텐트 삽입으로 풍선 혈관 성형술을 수행할 의도로 관상 동맥 조영술을 받게 됩니다. 보존적 그룹에서 환자는 임박한 새로운 경색 또는 재발성 허혈이 있는 경우에만 관상동맥조영술과 혈관성형술을 받게 됩니다. 침습적 그룹에서 풍선 혈관성형술은 무작위화 후 가능한 한 빨리 수행됩니다. 생존력이 없는 환자는 무작위 배정되지 않고 대조군으로 참여하게 됩니다.
