Filter by:To study the relation between ISR and neutrophil-to-lymphocyte ratio (NLR), novel biomarkers (high-sensitivity CRP (hs-CRP), bone morphogenetic protein-2 (BMP-2) and other risk factors (age, sex, smoking, hypertension, diabetes, obesity, chronic kidney disease (CKD; creatinine clearance).
To demonstrate acceptable short term safety rates of the Drug-eluting Coronary Spur Stent System as a primary treatment for coronary in-stent restenosis.
This study is aimed at making a comparison of the safety and efficacy of standard drug therapy (control group), standard drugs combined with lose-dose colchicine therapy (colchicine group) and standard drug combined with prednisone therapy (prednisone group) in patients with coronary heart disease who suffered from recurrent In-stent restenosis (RISR).
This study will be a prospective, randomized clinical trial to compare standard practice guided by usual care testing to CT-FFR-guided management in patients with in-stent restenosis.
This is a prospective single center, randomized controlled clinical study aimed to compare the clinical and angiographic follow-up results of patients with in-stent restenosis(ISR) after coronary drug eluting stent(DES) implantation treated by fractional flow reserve -guided and angiography guided drug eluting balloon(DEB) intervention. This study intends to confirm the clinical benefits of optimizing DEB intervention of DES-ISR by FFR.
This study is a prospective, registry trial aimed to compare the clinical and angiographic outcomes of OCT-guided and angiography-guided PCI in patients with coronary DES-ISR.
In-stent restenosis remains one of the most challenging problems in patients after coronary artery angioplasty. Angiographically, it is discovered in 10% of the patients after drug-eluting stent (DES) implantation. There are multiple factors causing restenosis, which can be divided into two major groups: first vessel-dependent (based on the vessel's tortuosity, dimensions and lesion's calcification, all leading to suboptimal stent expansion), and second dependent on the inflammatory processes caused by the intervention. Study objectives is the analysis of the possible correlation between allergy to metals utilised during the stent manufacturing (nickel, cobalt, chromium, molybdenum, tungsten) and in-stent restenosis occurence. The angiographic results of stent implantation, and in-stent restenosis will be assessed independently by two skilled interventional cardiologists, and in case of their discrepant opinions, the decision will be made on the basis of the third cardiologist. The tests will be applicated during the hospitalisation, then read after 48 hours and 72 hours, and subsequently interpreted by the skilled dermatologist, during the hospital stay or afterwards.
