Key result
Angiographically visible collaterals in STEMI patients were associated with a lower likelihood of cardiogenic shock and a tendency toward longer survival.
Why the study?
Does the presence of angiographically visible collaterals reduce cardiogenic shock and improve survival in STEMI patients?

Angiographically visible collaterals in STEMI patients are associated with a lower likelihood of cardiogenic shock and potentially longer survival.
Angiographically visible collaterals are seen in a minority of STEMI patients, predominantly to the RCA and in patients with delays to reperfusion. Patients with visible collaterals were less likely to have cardiogenic shock and tended to have a longer survival. Further studies will determine the mechanisms of collateral formation and their protective associations.
