FFR-Guided Revascularization in Atherosclerotic Renal Artery Stenosis: A Randomized Controlled Trial

For patients with atherosclerotic renal artery stenosis, the results of randomized controlled trials published in recent years have failed to demonstrate that renal artery stenting is superior to optimal medical therapy. However, these studies still have limitations. Fractional flow reserve (FFR) has been extensively studied in coronary artery disease, and it has been established that FFR-guided revascularization is superior to both angiography-guided percutaneous coronary intervention and medical therapy alone. Whether FFR can guide interventional treatment in patients with renal artery stenosis and hypertension is currently a hot topic in the field of renal artery stenosis research. Eligible patients meeting the inclusion criteria were enrolled. Pharmacologically induced FFR values were measured as the baseline. Patients with FFR ≥ 0.8 were randomly assigned to either the medical therapy group or the stenting group, while patients with FFR \< 0.8 underwent stent implantation. Changes in eGFR, 24-hour systolic blood pressure, and 24-hour diastolic blood pressure from baseline to 12 months were compared among the groups.

Pilot Study of IC14 (Atibuclimab), an Anti-CD14 Monoclonal Antibody, to Treat STEMI

Adults who have had an ST-elevation myocardial infarction and were treated with stent placement will receive an intravenous infusion of a monoclonal antibody in order to prevent further heart muscle damage. The goal is to learn if this treatment improves some measures of heart function and inflammation. The study treatment patients will be compared to patients who receive placebo (inactive treatment).

µQFR for Branch Stenosis After Single Stent in Bifurcation Lesions

Murray-law based single-view quantitative flow ratio (µQFR) has been recommended for guiding percutaneous coronary intervention (PCI) in selective patients. However, it's reliability has not been validated in bifurcation lesions which present complex anatomy and flluid conditions before and after PCI. The goal of this study is to investigate the diagnostic performance of µQFR in side branch after single-stent treatment for bifurcation lesions in patient with obstructive coronary artery diseases.

Dual Anti-Platelet Optimized Stent for High Bleeding Risk Patient

High risk of bleeding (HBR) is a determining factor for the duration of dual antiplatelet therapy (DAPT). Recent studies have shown that the use of one-month DAPT is beneficial in terms of ischemic as well as hemorrhagic events, particularly in HBR patients, compared with longer DAPT. European guidelines therefore authorize one-month DAPT in HBR patients presenting even an acute coronary syndrome. The HT Supreme Drug Coated Coronary Stent System (HT Supreme DES) is designed to promote reendothelialization as quickly as possible. That's why the stent is called "HT" Supreme, with "HT" standing for "Healing Targeted", enabling a DAPT of just 1 month in all-comers HBR patients. Thanks to these features, the investigators aim to demonstrate ischemic and hemorrhagic complication rates lower than those found in the literature with other stent.

Cognitive Improvement After Carotid Stenting in Hyperbaric Oxygen Therapy Trial

The purpose of CARE-HBOT study is to evaluate whether patients with symptomatic severe carotid artery stenosis with cognitive impairment who underwent hyperbaric oxygen therapy plus standard medical treatment after stent implantation could improve their cognitive function compared with those who underwent standard postoperative medical treatment.
