N2  - The multicenter prospective Lipid Rich Plaque (LRP) registry showed that nonculprit (NC) lipid-rich plaques identified by near-infrared spectroscopy (maxLCBI4mm >400) with an intravascular ultrasound plaque burden (PB) >70% and/or minimum lumen area (MLA) <4 mm2 within the maxLCBI4mm segment were more frequently associated with major adverse cardiac events (MACE) within 2 years. The aim of this sub-study was to report the relationship between initial clinical presentation and subsequent NC-MACE. Patients enrolled in the LRP study were stratified post hoc as having a stable angina pectoris or silent ischemia presentation versus acute coronary syndrome, excluding patients presenting with acute ST-elevation myocardial infarction. Among the 1552 patients, 717 presented with stable angina pectoris or silent ischemia. Patients presenting with acute coronary syndrome were more likely to be younger and Black, current smokers, and have less chronic kidney disease. Of the scanned nonculprit vessels, there was no difference between the 2 clinical presentation groups regarding lipidic content, and the rate of lipid-rich plaques (maxLCBI4mm >400) was 31.9% in both groups. Finally, there was no difference in NC-MACE at 2 years' follow-up, although within each group (stable versus acute coronary syndrome), the NC-MACE rate associated with maxLCBI4mm >400 was significantly higher than maxLCBI4mm <=400 (stable 13.8% vs 6.5%; acute patients 11.6% vs 6.3%, respectively). In conclusion, in patient groups that present with stable angina pectoris or silent ischemia versus acute coronary syndrome, the NC lipidic content was similar, as was NC-MACE, through 2 years of follow-up.
