ConclusionsConclusions
• Immediate PCI increased the rate of Immediate PCI increased the rate of periprocedural MI compared to a cooling periprocedural MI compared to a cooling down strategy of deferred PCIdown strategy of deferred PCI
• The results of the study suggest that there The results of the study suggest that there is no need to rush to PCI in non-refractory is no need to rush to PCI in non-refractory high risk NSTE-ACS patientshigh risk NSTE-ACS patients
