심장내과

기유정 교수

[전문분야]: 흉통, 호흡곤란, 협심증, 심근경색, 심부전, 심장성 쇼크, 고혈압, 고지혈증 / 만 19세이상

[전문진료]: 흉통에 대한 평가 및 치료, 관상동맥 협착 병변의 영상 및 생리학적 검사, 협심증 심근경색의 치료

치료 여정의 동반자가 되겠습니다

좁아진 관상동맥은 흉통, 호흡곤란 등으로 발현할 수 있지만, 모든 협착이 스텐트 시술을 필요로 하지는 않습니다.

관상동맥 협착 병변의 임상적인 중요성을 확인하여 정말 필요한 병변에 치료하겠습니다.

환자의 단기 문제 해결뿐 아니라 10년 후를 바라보고 치료하는 치료 여정의 동반자가 되겠습니다.
