Filter by:Prospective, multi-centre, randomized, open-label, parallel comparisons to evaluate - the incidence of bleedings (COSTA-Bleed) and - the incidence of ischemic and bleeding events (COSTA-Outcome) following a therapy with the abluminal sirolimus coated bio-engineered stent (COMBO stent) in association with short-term single antiplatelet therapy as compared to a guidelines-based strategy in patients with coronary artery disease with an indication for chronic oral anticoagulant therapy.
Contrast-induced nephropathy (CIN) has remained significant and severe complication of angiographic procedures despite the increasing use of preventative methods. It has been associated with prolonged hospital stay, high morality and the need for dialysis. Since classically used creatinine for diagnosing of CIN does not reflect the degree of tubular injury before 24-48 hours after exposure to contrast media alternative earlier biomarkers and preventative methods are needed. Remote ischemic preconditioning is a non-invasive and safe method which in some studies has been reported to protect against contrast-induced nephropathy. The purpose of this study is to evaluate the effect of remote ischemic preconditioning (RIPC) (1) as an additional method to standard treatment to prevent subclinical and clinical contrast-induced acute kidney injury and (2) to assess its effect on functional properties of arterial wall, organ damage biomarkers and low molecular weight metabolites.
To compare the safety and efficacy of FFR (fractional flow reserve)-guided percutaneous coronary intervention (PCI) strategy with IVUS (intravascular ultrasound [IVUS])-guided PCI in patients with intermediate coronary stenosis.
The purpose of the study is to compare two different types of decision support materials for patients considering treatment for chest pain or chest discomfort from heart disease.
We had little experience in coronary intervention with recently introduced newer drug-eluting stent (DES) platforms, despite great anticipation, and optimal duration of dual antiplatelet therapy (DAPT) for these stent systems still needs to be established. Herein, we plan the HOST-coronary intervention with next-generation drug-eluting stent platforms and abbreviated dual antiplatelet therapy (HOST-IDEA) trial to compare single antiplatelet therapy (SAPT) after 3-month DAPT with 12-month DAPT in all-comers undergoing coronary intervention with third-generation DES with the thinnest struts. P2Y12 inhibitor treatment is added to aspirin during the 3-months period after the stenting, and this abbreviated duration of DAPT will be compared with conventional 1-year mandatory DAPT regimen in a 1:1 randomized stratification. Net adverse clinical events (NACEs), a composite of cardiac death, target vessel related myocardial infarction, clinically-drivent target lesion revascularization, definite or probable stent thrombosis and major bleeding is a primary endpoint for evaluating safety and efficacy of the difference of DAPT duration. 1-year target lesion failure (TLF) as a composite of cardiac death, target vessel related myocardial infarction and clinically driven target lesion revascularization will be identified as a secondary ischemic outcome. 1-year major bleeding events classified as BARC type 3 or 5 bleeding events will be identified as a secondary bleeding outcome. With this trial, you will be able to get clear insight on the behavior of newer DES platforms. Reference data for the shortened mandatory DAPT regimen will also be delineated in the selected patients, and it might be helpful to those who need it.

A phase 2a, multicenter, randomized, double-blind, placebo-controlled study in adults with stable angina to evaluate the effect of erenumab (AMG 334) compared to placebo on exercise time during an exercise treadmill test.
The investigators sought to investigate the efficacy of low frame rate (fluoroscopy at 7.5 frames per second (FPS) and Cine at 10 pulse per second (PPS) vs. conventional (15 FPS and 15 PPS) on radiation dose to the patient and the operator during coronary angiography and intervention. In addition, investigators sought to qualitatively assess the effect, if any, of the low frame rate on angiographic image quality.
Platelets play a major role in thrombus formation and platelet size, measured by Mean Platelet Volume (MPV) correlates with platelet activity. MPV is increased in patients with Myocardial Infarction (MI) and is an independent predictor of adverse events in patients with ST Elevation Myocardial Infarction (STEMI) . Data on MPV in patients with stable angina is limited. Aspirin and clopidogrel are antiplatelet agents administered routinely to patients undergoing PCI and are required for stent patency. MPV is not known to be affected by low dose Aspirin. Treatment with clopidogrel is thought to reduce MPV in-vitro but the magnitude of this reduction in MPV is unclear, especially in patients with stable angina undergoing PCI. An inverse correlation also exists between MPV and platelet count . The investigators aim to assess if a change occurs in MPV (∆ MPV) after routine clopidogrel administration in patients with stable angina undergoing PCI.
This is a single-center, open-label, randomized controlled trial. Patients with stable angina pectoris without use of dual antiplatelet therapy or anticoagulation therapy scheduled for coronary artery bypass grafting (CABG) at Karolinska University Hospital in Stockholm, Sweden will be eligible. This study investigates in patients having undergone CABG whether increasing the dose or the frequency of acetylsalicylic acid (ASA) treatment improves the efficacy of ASA regarding platelet inhibition compared to the standard dosing for cardiovascular prevention (75 mg once daily) in the first three months after surgery. Patients will be randomly assigned to postoperative ASA dose 75mg once daily, 75mg twice daily or 160 mg once daily. The study dose ASA will be started at hospital discharge and continued of three months. Blood samples for serum thromboxane B2 (TxB2) and other analyses will be taken before surgery, before discharge, and after one and three months. All available data will be collected prospectively. Informed consent will be obtained from patients meeting the inclusion criteria before the initiation of any study-specific procedures.
