The Effect of Pioglitazone on Neointima Volume and Inflammatory Markers
Diabetes MellitusCoronary Artery StenosisPeople with diabetes mellitus are more prone to coronary heart disease, stroke, and peripheral vascular disease, and diabetes mellitus has been regarded as an independent risk factor for the progression of coronary artery disease. Several studies have been reported that diabetes increased the risk of cardiovascular mortality in both men and women. With the introduction of drug-eluting stents (DESs), the angiographic rates of restenosis at later months have reduced dramatically in several studies. However, even with DESs, diabetic patients showed increased rates of restenosis and late loss index compared with nondiabetic patients. Diabetes has been considered to be a predictor of poor prognosis after percutaneous coronary intervention with drug-eluting stents. Long-term clinical and angiographic outcomes after percutaneous coronary intervention (PCI) with drug-metal stents (DESs) have been demonstrated to be worse in diabetic patients compared with nondiabetic patients. In the era of DESs, no study has demonstrated the clinical and angiographic outcomes in diabetic patients after zotarolimus-eluting stent implantation by using intravascular ultrasound (IVUS). Pioglitazone is used in the treatment of diabetic patients. Thiazolidinediones increase insulin sensitivity and show favorable effect on blood glucose levels and lipid profiles. The effect of pioglitazone on neointima volume and inflammatory markers has not been compared in prospective manner after zotarolimus-eluting stent implantation. The purpose of this prospective, randomized, single blinded trial is to compare the effect of pioglitazone on inflammatory markers and neointima volume by using IVUS in diabetic patients.
SPIRIT PRIME Clinical Trial
Myocardial IschemiaCoronary Artery Stenosis3 moreTo evaluate the safety and effectiveness of the XIENCE PRIME and XIENCE PRIME Long Lesion (LL) Everolimus Eluting Coronary Stent System (EECSS) in improving coronary luminal diameter in subjects with symptomatic heart disease due to a maximum of two de novo native coronary artery lesions, each in a different epicardial vessel.
Excel Drug-Eluting Stent Pilot Clinical Registry
Coronary StenosisThe Trial aims to evaluate long-term efficiency of Excel stent in the inhibition of restenosis as well as the safety after the cessation of the 6-month anti-platelet drug treatment.
Thin Strut Sirolimus-eluting Stent in All Comers Population vs Everolimus-eluting Stent
Coronary StenosisThe primary objective of this study is to compare the performance of SUPRAFLEX to that of XIENCE in an all-comers patient population with symptomatic ischemic heart disease. The patients will be followed through 3 years for major clinical events.
Shockwave Coronary Lithoplasty Study
Coronary StenosisThe objective of this clinical trial is to study the early safety and feasibility of the Shockwave Coronary Lithoplasty System. To demonstrate that the Shockwave device can safely and effectively deliver localized shockwave energy for balloon dilatation of calcified, stenotic, de novo coronary lesions.
Optical Coherence Tomography to Investigate FFR-Guided DEB-only Elective Coronary Angioplasty
Stable AnginaCoronary StenosisWe aimed to evaluate feasibility and the 6-month angiographic and OCT results of FFR - guided use of paclitaxel-eluting balloons (Sequent Please™, B Braun) with provisional bare metal stenting for elective PCI of de novo coronary lesions.
XIENCE V® USA Dual Antiplatelet Therapy (DAPT) Cohort
Chronic Total Occlusion of Coronary ArteryVascular Disease5 moreXIENCE V USA is a prospective, multi-center, multi-cohort postapproval study. The objectives of this study are To evaluate XIENCE V EECSS continued safety and effectiveness during commercial use in real world settings, and To support the Food and Drug Administration (FDA) dual antiplatelet therapy (DAPT) initiative. This initiative is designed to evaluate the composite of all death, myocardial infarction (MI) and stroke (MACCE) and the survival of patients that are free from Academic Research Consortium (ARC) definite or probable stent thrombosis (ST) and that have been treated with drug eluting stents (DES) and extended dual antiplatelet therapy.

Coronary OcclusionThrombosis (Stent Thrombosis)6 moreThis is a prospective, randomized, active-controlled, open label, parallel two-arm, multi-center, post-approval study descriptively comparing the XIENCE V EECSS to the CYPHER SELECT PLUS Sirolimus-Eluting Coronary Stent System (SECSS) ("CYPHER SELECT PLUS") during commercial use in China.
The Real-World Endeavor Resolute Versus XIENCE V Drug-Eluting Stent Study in Twente
Coronary Artery DiseaseAngina Pectoris3 moreThe TWENTE Study is a single center prospective single-blinded randomized study. Randomization will involve the type of Drug-Eluting Stent (DES) used in study population. Patients will be blinded to the type of DES they will receive. The general practitioner of the patient will be requested not to disclose this information to the patient. Analysts who perform the data analyses will be blinded to the type DES used as well.
