Prognostic impact of PCI in patients with chronic total occlusion on non-infarct-related artery in acute STEMI with cardiogenic shock / 中国实用内科杂志

ABSTRACT

Chronic total occlusion(CTO) located at a non infarct-related artery in patients with acute ST-segment–elevation myocardial infarction is linked to attack of cardiogenic shock and increased mortality.It has been demonstrated that direct PCI of infarct-related artery(IRA) in STEMI patients with multi-vessel lesions will restore the blood flow of IRA and improve prognosis of cardiogenic shock. But how to deal with non-target CTO lesions? Whether successful CTO PCI will reduce cardiovascular events, cardiovascular mortality and heart failure remains a research hotspot.
