Coronary artery reblockage remains still a drawback of percutaneous coronary interventions even in the era of drug-eluting stents (DES). DESs working principle consists of the delivery of controlled amounts of antiproliferative agents at the local level, which results in the suppression of neontimal proliferation, the main cause of lumen re-narrowing after stent implantation. At present, several DES platforms have been developed and evaluated for clinical use. They differ between them with regard to the stent type, anti-proliferative drug, presence or absence of polymers employed for drug storage and modification of drug-release kinetics as well as type of polymer used for this purpose. Although their mid-term efficacy has been well-established, there is an ongoing debate on the potential of an increased incidence of late stent thrombosis, particularly after discontinuation of thienopyridine therapy, as well as of delayed onset of restenosis or catch-up phenomenon with DESs. Based on animal and human pathological data, investigators have linked the above-mentioned concerns to the presence of permanent polymers in DESs, which have a proinflammatory and prothrombogenic potential, and sometimes may induce a hypersensitivity reaction. On the other hand, lack of or delayed reendothelialization is considered an important factor for development of coronary reblockage. Estradiol has been shown to promote rapid reendothelialization of the stent and to reduce the restenosis after PCI. This trial will compare the anti-restenotic efficacy of the polymer-free rapamycin plus 17β estradiolvalerat -eluting stent with that of the polymer-free rapamycin-eluting stent in patients with coronary artery disease. The ISAR stent is a rough surface stainless steel stent which allows coating without the need of polymer (PF ISAR stent) in the cath lab.

To assess the long-term outcomes of patients treated with sirolimus-eluting Stentys stent in a real-life setting.
Reports of long-term outcomes of patients treated with drug-eluting stents in total coronary occlusions are limited. We analyzed clinical outcomes of patients treated with the zotarolimus-eluting Reso...
There are limited data on the clinical value of routine postdilatation using noncompliant balloons after contemporary drug-eluting stent implantation.
This study sought to assess whether the predilation, scaffold/stent sizing, and postdilation (PSP) score for bioresorbable scaffold (BRS) implantation was associated with outcomes following metallic d...
An abluminal biodegradable polymer sirolimus-eluting stent versus a durable polymer everolimus-eluting stent in patients undergoing coronary revascularization: 3-year clinical outcomes of a randomized non-inferiority trial.
The Cordimax stent has proved non-inferior to the Cypher Select durable polymer sirolimus-eluting stent for the primary endpoint of angiographic in-stent late luminal loss and in-stent mean diameter s...
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
A multiprotein complex consisting of MTOR KINASE; MLST8 PROTEIN; rapamycin-insensitive companion of mTOR protein (RICTOR PROTEIN); and PRR5 (proline-rich protein 5). Like MTORC1, it also regulates cell growth and proliferation in response to growth factors but may not be as sensitive to nutrient availability and is insensitive to SIROLIMUS. In contrast to MTORC1, it can regulate the ACTIN CYTOSKELETON through RHO GTPASES to promote the formation of STRESS FIBERS. The mTORC2 complex also plays a critical role in AKT1 PROTEIN KINASE phosphorylation and activation.
Stents that are covered with materials that are embedded with chemicals that are gradually released into the surrounding milieu.
An analytical technique for resolution of a chemical mixture into its component compounds. Compounds are separated on an adsorbent paper (stationary phase) by their varied degree of solubility/mobility in the eluting solvent (mobile phase).
Separation systems containing a relatively long-lived parent radionuclide which produces a short-lived daughter in its decay scheme. The daughter can be periodically extracted (milked) by means of an appropriate eluting agent.
