Primary percutaneous coronary intervention (PCI) has been found to be superior, in terms of hospital mortality and long-term outcome, compared with thrombolytic therapy in patients with acute myocardial infarction (AMI). However, the clinical benefits of primary PCI have not been precisely evaluated...

경피적 관상동맥 중재술이 단기 및 장기적으로 임상 효과가 우수하다고 보는 이유는? | 최근에 급성 심근경색증 환자에서 혈전용해제보다 일차적으로 시행하는 경피적 관상동맥 중재술(percutaneouscoronaryintervention, PCI)이 단기 및 장기적으로 임상 효과가 우수하다고 보고되고 있으며[1-4], 2004년 American College of Cardiology/American Heart Association (ACC/AHA) 치료 지침에 일차적 PCI의 효과가 인정되고 ClassI 적응증으로 분류되고 있다[5][6]. 2년 이상 장기간 추적 관찰한 경우에도 일차적 PCI를 시행 받은 환자가 혈전용해제를 투여 받은 환자들에 비하여 심근경색증의 재발이나 사망률이 낮은 것으로 알려져 있다[7][8]. 그러나 이러한 연구들에서 고령 환자들은 제외되어 있고 출혈 등의 합병증 발생률이 더 높아서, 젊은 환자에 비하여 PCI나 혈전용해제 치료 등의 적극적인 재관류술이 적게 시행되었다[9][10]. | |
성공적인 스텐트 삽입이란? | 본원에서 시행한 스텐트(stent) 삽입술은 대부분 관상동맥 풍선확장술 이후에 협착이 잔존하는 경우에 스텐트를 삽입하였다.성공적인 스텐트 삽입은 스텐트 삽입 후 잔존협착이 30% 미만인 경우로 정의하였고 스텐트 삽입 후 잔존협착이 남아 있는 경우에는 부가적인 풍선확장술을 시행하여 잔존협착이 최소가 될 수 있도록 시술하였다. | |
혈전용해제는 어느경우에 사용 가능한가? | 혈전용해제가 노인 환자에서 효과를 보이지만 출혈성 뇌경색과 출혈성 합병증을 일으키며, 20%의 높은 사망률 때문에 일부환자에서만 혈전용해제를 사용할 수 있다[22-24]. 최근 보고에 따르면 노인 환자의 급성심근경색증의 치료에 있어서 혈전용해제보다 일차적 PCI가 단기 및 장기적 임상 효과가 좋음이 보고되고 있다[25-30]. |
