Abstract
BackgroundTo evaluate the effect of stent boost subtract (SBS) imaging on stent underexpansion during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) by optical coherence tomography (OCT).MethodsOne hundred thirty-eight STEMI patients who underwent drug-eluting stent (DES) implantation were prospectively recruited and divided into the SBS group (69 cases) and the CAG group (69 cases) according to whether SBS was used to guide PCI. Finally, OCT was performed on all enrolled patients, and the OCT results were used as the gold standard to evaluate the impact of standard SBS technology on stent underexpansion immediately after DES implantation.ResultsSBS identified 51 patients (24%) with stent underexpansion while OCT identified 56 patients (27.2%). SBS has a sensitivity of 80%, a specificity of 96%, a positive predictive value of 88%, and a negative predictive value of 93% for identifying stent underexpansion.ConclusionCompared with OCT, SBS technology is a rapid stent imaging evaluation method that can accurately quantify the stent expansion level and is time-saving and economical.
Highlights
Percutaneous coronary intervention (PCI) is currently the most important method for the treatment of acute ST-segment elevation myocardial infarction (STEMI) [1, 2]
Stent underexpansion assessment A total of 206 lesions were included in stent boost subtract (SBS) and optical coherence tomography (OCT) image analysis
SBS has a sensitivity of 80%, specificity of 96%, positive predictive value of 88%, and negative predictive value of 93% for identifying stent underexpansion (Additional file 1: Table S1)
Summary
Percutaneous coronary intervention (PCI) is currently the most important method for the treatment of acute ST-segment elevation myocardial infarction (STEMI) [1, 2]. STEMI patients due to the complexity of the operation, the high cost, and the need for experienced interventional personnel to perform the operation [8, 9]. Stent boost subtracts (SBS) is a newly developed imaging technology. The purpose of this study was to use OCT as the gold standard to evaluate the effect of SBS on stent underexpansion in guiding PCI in patients with STEMI. To evaluate the effect of stent boost subtract (SBS) imaging on stent underexpansion during percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) by optical coherence tomography (OCT)
