      Predictive value of plaque morphology assessed by frequency-domain optical coherence tomography for impaired microvascular perfusion after elective stent implantation: the intracoronary electrocardiogram study

      Aims This study was undertaken to assess the association between plaque features at culprit lesions assessed by frequency-domain optical coherence tomography (FD-OCT) and impaired microvascular perfusion estimated by intracoronary electrocardiogram (IcECG) after elective percutaneous coronary intervention (PCI). Furthermore, we investigated whether IcECG could predict future cardiac events. Methods and results This study consisted of 84 patients who underwent both FD-OCT and IcECG during PCI. Patients were classified into two groups based on ST-segment elevation (ST-E) on IcECG after the procedure; ST-E (−) group ( n  = 53) and ST-E (+) group ( n  = 31). Minimum fibrous cap thickness was significantly thinner in the ST-E (+) group ...

    2. Longitudinal extent of lipid pool assessed by optical coherence tomography predicts microvascular no-reflow after primary percutaneous coronary intervention for ST-segment elevation myocardial infarction

      Longitudinal extent of lipid pool assessed by optical coherence tomography predicts microvascular no-reflow after primary percutaneous coronary intervention for ST-segment elevation myocardial infarction

      Background Distal embolization during percutaneous coronary intervention (PCI) may deteriorate microvascular reperfusion in patients with ST-elevation myocardial infarction (STEMI). Reperfusion at the coronary microvascular level is important for STEMI and culprit plaque is associated with distal embolization and microvascular reperfusion. ST-segment resolution (ST-R) in the electrocardiogram reflects microvascular reperfusion after primary PCI. Longitudinal extent of lipid pool assessed by optical coherence tomography (OCT) may predict the risk of failure of microvascular reperfusion after primary PCI. Methods and results This study consisted of 39 patients with STEMI who underwent primary PCI within 24 h after the onset of chest pain. Immediately ...
