DOI: 10.1016/j.ahj.2017.07.017
Abstract: Background Functional assessment of non–infarct‐related artery lesions during primary percutaneous coronary intervention (PCI) might be useful to avoid revascularization of nonsignificant stenosis and staged procedures, thus reducing hospital stay. We aimed to assess the diagnostic… read more here.
