Multivessel vs. Culprit-Only Primary PCI in
STEMI Patients with Shock, Cardiac Arrest
• 169 STEMI patients with resuscitated cardiac
arrest and cardiogenic shock and multivessel
disease.
– Six-month survival was improved with multivessel
PCI compared with culprit-only PCI (43.9% vs.
20.4%; P = 0.0017).
– The survival advantage was driven by a reduction
in the composite of recurrent cardiac arrest and
death from shock (50.0% vs. 68.0%; P = 0.024).

• 理解指南
可以 ≠ 必须
• It remains to be determined how
clinicians can identify lesions that
should be revascularized beyond the
culprit lesion and whether complete
revascularization should be performed in
single- or multi-stage procedures.
• At present, multivessel PCI during STEMI
should be considered in patients with
cardiogenic shock in the presence of
multiple, critical stenoses or highly
unstable lesions (angiographic signs of
possible thrombus or lesion disruption),
and if there is persistent ischaemia
after PCI on the supposed culprit lesion.
