Use of intravascular ultrasound (IVUS) promotes better clinical outcomes for coronary intervention in complex lesions. However, randomized data demonstrating the usefulness IVUS are limited lesions treated with drug-eluting stents.To determine whether long-term IVUS-guided stent implantation superior to those angiography-guided patients long lesions.The Impact Intravascular Ultrasound Guidance on Outcomes Xience Prime Stents Long Lesions (IVUS-XPL) randomized, multicenter trial was conducted...
<h3>Importance</h3> Discontinuing aspirin after short-term dual antiplatelet therapy (DAPT) was evaluated as a bleeding reduction strategy. However, the strategy of ticagrelor monotherapy has not been exclusively in patients with acute coronary syndromes (ACS). <h3>Objective</h3> To determine whether switching to 3 months DAPT reduces net adverse clinical events compared ticagrelor-based 12-month ACS treated drug-eluting stents. <h3>Design, Setting, and Participants</h3> A randomized...
There have been no randomized studies comparing intravascular ultrasound (IVUS)-guided versus conventional angiography-guided chronic total occlusion (CTO) intervention using new-generation drug-eluting stent Therefore, we conducted a prospective, randomized, multicenter trial designed to test the hypothesis that IVUS-guided CTO is superior intervention.After successful guidewire crossing, 402 patients with CTOs were group (n=201) or and secondarily Resolute zotarolimus-eluting stents Nobori...
BACKGROUND: Stopping aspirin within 1 month after implantation of a drug-eluting stent for ticagrelor monotherapy has not been exclusively evaluated patients with acute coronary syndrome. The aim this study was to investigate whether <1 dual antiplatelet therapy (DAPT) is noninferior 12 months ticagrelor-based DAPT adverse cardiovascular and bleeding events in METHODS: In randomized, open-label, noninferiority trial, 2850 syndrome who underwent at 24 centers South Korea were randomly...
In patients with coronary artery disease, some guidelines recommend initial statin treatment high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is begin moderate-intensity and titrate specific LDL-C goal. These alternatives have not been compared head-to-head clinical trial involving known disease.To assess whether treat-to-target strategy noninferior of for long-term outcomes disease.A randomized, multicenter,...
Abstract Background and Aims Drug-coated balloons (DCBs) have demonstrated favourable outcomes following endovascular therapy for femoropopliteal artery (FPA) disease. However, uncertainty remains whether the use of intravascular ultrasound (IVUS) can improve DCBs. Methods This prospective, multicentre, randomized trial, conducted at seven centres in South Korea, compared IVUS-guided vs. angiography-guided angioplasty treating FPA disease with Patients were assigned to receive (n = 119) or...
<h3>Objective</h3> To investigate the long-term prognostic implications of contrast-induced acute kidney injury (CI-AKI) with transient or persistent renal dysfunction in myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI). <h3>Design</h3> A retrospective observational registry study. <h3>Setting</h3> Clinical follow-up after PCI. <h3>Patients and methods</h3> total 1041 PCI-treated AMI from Infarction Prognosis Study registry. CI-AKI was defined as an...
Background— We investigated the incidences, predictors, and clinical outcomes of acute late stent malapposition detected by optical coherence tomography (OCT) after drug-eluting implantation. Methods Results— analyzed OCT images from 351 patients with 356 lesions who received poststent follow-up examinations. Acute was observed in 62% lesions. Approximately half malappositions were located within edges stents. Severe diameter stenosis, calcified lesions, long stents independent predictors...
