BACKGROUND This article aims to investigate the changes of plasma cystatin C concentration (PcyC), and to evaluate the relationship between PcyC and acute coronary syndrome. METHODS A total of 126 consecutive patients with coronary artery disease (CAD) were enrolled in this study, consisting of 34 patients with stable angina pectoris (SAP), 56 patients(More)
OBJECTIVES The authors sought to report the temporal stability of an untreated, nonculprit lesion phenotype in patients presenting with ST-segment elevation myocardial infarction (STEMI). BACKGROUND The temporal stability of the untreated, nonculprit lesion phenotype has been studied using intravascular ultrasound-virtual histology (IVUS) in patients with(More)
BACKGROUND The impact of OSA treatment with CPAP on percutaneous coronary intervention (PCI) outcomes remains largely unknown. METHODS Between 2002 and 2012, we identified 390 patients with OSA who had undergone PCI. OSA was diagnosed through in-laboratory sleep studies and defined by an apnea-hypopnea index ≥ 5 events/h. The cohort was divided into three(More)
OBJECTIVES The aim of this study was to understand the impact of attenuated plaque on distal embolization during stent implantation in patients with acute myocardial infarction (AMI). BACKGROUND Attenuated plaques identified by grayscale intravascular ultrasound (IVUS) might predict transient deterioration in coronary flow and/or no-reflow during(More)
BACKGROUND The incidence and mechanisms of acute and late stent malapposition after primary stent implantation in ST-segment elevation myocardial infarction remain unclear. METHODS AND RESULTS The Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) trial was a dual-arm, factorial, randomized trial comparing(More)
Noncalcific attenuated plaques identified by grayscale intravascular ultrasound (IVUS) are often seen in patients with acute coronary syndromes and have been associated with no reflow and creatine kinase-MB elevation after percutaneous coronary intervention. Histopathology has shown cholesterol clefts, microcalcification, or organized thrombus. One hundred(More)
It is not clear whether the thin struts and different alloy of a cobalt chromium stent will cause greater acute stent recoil compared to conventional stainless steel stents. We used postintervention intravascular ultrasound (IVUS) examinations to study 99 patients with 116 stented lesions: 61 Xience/Promus stents (cobalt chromium stent group) and 27 Taxus(More)
Percutaneous coronary intervention with drug-eluting stents (DES) may achieve midterm outcomes comparable to coronary artery bypass grafting (CABG) for unprotected left main coronary artery disease, but few real-world, long-term studies have been reported. In this study, 376 patients with unprotected left main coronary artery disease who underwent DES(More)
We present a new mechanism called Elon for enabling efficient and long-term reprogramming in wireless sensor networks. Elon reduces the transferred code size significantly by introducing the concept of <i>replaceable</i> component. It avoids the cost of hardware reboot with a novel software reboot mechanism. Moreover, it significantly prolongs the(More)
— We study a class of optimal control problems that are encountered in consensus and synchronization networks. These are characterized by structural constraints that arise from the lack of the absolute measurements for a part of the state vector. In order to deal with these constraints, we introduce a coordinate transformation to eliminate the average mode(More)
