Active clinical trials for "Coronary Artery Disease"

CLOTILDIA is a single-center, prospective, randomized, open label, cross-over study evaluating the effects of ticagrelor versus high-dose clopidogrel on endothelial function and platelet reactivity in patients with type-2 diabetes mellitus (T2DM) treated with percutaneous coronary intervention (PCI).

The purpose of this study is to perform a first-in-man assessment of feasibility, exploratory efficacy and clinical performance of the novel Angiolite drug-eluting stent (iVascular, Barcelona, Spain) utilizing intracoronary optical coherence tomography (OCT).

In patients undergoing off-pump coronary artery bypass (OPCAB) surgery with different anesthesia regimens: remifentanil (0.75 mcg/kg/min) and propofol (TCI effect-site concentration 0.8-1.5 mcg/ml) (Group -RP); remifentanil (0.75 mcg/kg/min) and sevoflurane (end-tidal 0.8 vol%) (Group-RS), or sevoflurane (end-tidal 1.2-2.8 vol%)-sufentanil (TCI effect site concentration 0.35-0.75 ng/ml) (Group-SS), intergroup difference in the level of Troponin I (c-TnI) and creatinine kinase subtype-MB is determined before surgery (control), during vascular graft harvesting (harvesting), after completing graft construction (postgrafting), and one day after surgery (postoperative).

It is well-known that non-optimal stent implantation associated with under-expansion or incomplete strut apposition during percutaneous coronary intervention (PCI) leads to a higher incidence of restenosis and stent thrombosis. OCT-guided PCI with metallic stent has previously been shown to be safe and feasible, resulting in better clinical outcomes compared with angiography-only guided PCI. Everolimus-eluting bioabsorbable vascular scaffold (BVS; Abbott Vascular, Santa Clara, CA, USA) was made from a bioabsorbable polylactic acid backbone which is coated with a more rapidly absorbed polylactic acid layer that contains and controls the release of the antiproliferative drug, everolimus. BVS has a number of proposed advantages over current metallic stent technology. These include elimination of chronic sources of vessel irritation and inflammation, which can reduce the potential risk of late scaffold thrombosis after complete scaffold bioresorption. Although the current generation of the Absorb BVS have larger strut thickness of 150 μm compared with 80 μm of strut of Xience stent, the acute recoil of the polymeric device was similar to that of metallic stent. However, operators tented to use dilating devices less aggressively because of the concerns about limitation in elongation-at-break of polylactide. Previous studies reported 20-30% of under-expansion or malapposition with BVS, which would increase the risk of adverse events including late stent thrombosis. OCT-guidance may improve more optimized scaffold placement and also better outcomes. Therefore, investigators will compare OCT guidance and angiography-only guidance for PCI with BVS regarding incomplete scaffold apposition and neointimal scaffold coverage. Investigators are also going to compare these two strategies regarding clinical outcomes with verification of the cut-off value by OCT-acquired uncovered scaffold rate.

HIV-infected patients with intermediate-high risk have a high prevalence of CAD and a substantial proportion of obstructive CAD. Degree of stenosis is associated with immunoactivation (lymphocyte and monocyte) and microbial translocation

Published data indicate that obstructive sleep apnea syndrome (OSAS) worse the prognosis of coronary artery disease (CAD) and that oxidative stress can link this 2 diseases. Investigators hypothesise that oxidative stress decrease after 3 months of continuous positive airway pressure (CPAP) in this specific population. The results may have major implication in the comprehension of physiopathologic processes linking OSAS and CAD and in the treatment of OSAS in this specific population.

Primary percutaneous coronary intervention (PCI) is the main reperfusion therapy in patients with ST-elevation myocardial infarction (STEMI). The optimal platelet inhibition at the time of PCI is fundamental, however, the comparative speed of action of cangrelor as opposed to tirofiban and to chewed or integer loading dose of prasugrel is unknown. The purpose of this trial is to assess the inhibition of platelet aggregation with different regimens on platelet inhibition (tirofiban bolus+infusion, cangrelor bolus+infusion, prasugrel chewed loading dose, prasugrel integer loading dose) in the early phase of primary PCI.

The purpose of this study was to assess and compare the feasibility, success and safety of Transradial approach (TRA) verses Transfemoral approach (TFA) for diagnostic and therapeutic coronary angiography and coronary interventions, in terms of procedural time, access time, fluoroscopy time, procedural failure, , length of hospital stay in terms of days in hospital, Complications in terms of thrombophlebitis, hematoma, ecchymosis, infections thrombosis of vessel, MACE, Stroke and others.

Assessment of the safety and clinical performance of a coronary stent system in de novo coronary artery lesions

This study evaluates a smartphone-based cardiac rehabilitation program in adults with coronary artery disease. Half of patients will participate in a smartphone-based cardiac rehabilitation program while the other half will receive standard-of-care.
