Detection by near-infrared spectroscopy of large lipid cores at culprit sites in patients with non-st-segment elevation myocardial infarction and unstable angina
ObjectiveThis study was performed to assess the lipid burden of culprit lesions in non-ST-segment elevation myocardial infarction (non-STEMI) and unstable angina (UA). BackgroundA recent intracoronary near-infrared spectroscopy (NIRS) study showed 85% of STEMI culprit lesions have a maximum lipid core burden index in 4-mm (maxLCBI(4mm))400. Whether culprit lesions in non-STEMI and UA are character
