This study aimed to assess hibernating myocardium (HM), as determined by single\u2010photon emission computed tomography (SPECT) and <jats:sup>18<\/jats:sup>F\u2010FDG positron emission tomography (PET), and to compare the benefits of PCI and optimal medical therapy (OMT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective study collected data from 332 patients with CTO and ischemic left ventricular dysfunction. The study compared patients who underwent PCI or OMT via propensity score matching (PSM) analysis which was performed with a 1:2 matching protocol using the nearest neighbour matching algorithm. The primary endpoint of the study was the occurrence of major adverse cardiac events (MACE), defined as a composite of cardiac death, readmission for worsening heart failure (WHF), revascularization and myocardial infarction (MI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After PSM, there were a total of 246 individuals in the PCI and OMT groups. Following Cox regression, hibernating myocardium\/total perfusion defect (HM\/TPD) was identified as an independent risk factor (hazard ratio (HR): 1.03, 95% confidence interval (CI): 1.008\u20131.052, <jats:italic>p<\/jats:italic>\u2009=\u2009.007). The cut\u2010off value of HM\/TPD was 38%. The results of the subgroup analysis suggest that for patients with HM\/TPD &gt;38%, the OMT group had a greater risk of MACE (<jats:italic>p<\/jats:italic>\u2009=\u2009.035). A sensitivity analysis restricting patients with single\u2010vessel CTO lesions, HM\/TPD remained an independent predictor (HR 1.025, 95% CI 1.008\u20131.043, <jats:italic>p<\/jats:italic>\u2009=\u2009.005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>HM\/TPD is an independent predictor of MACE, and for patients with HM\/TPD\u2009&gt;\u200938%, CTO\u2010PCI had a lower risk of MACE compared with OMT.
