Filter by:The purpose of this research study is to compare the effectiveness of intravenous isotonic sodium bicarbonate with intravenous isotonic sodium chloride and oral N-acetylcysteine (NAC) with oral placebo for the prevention of serious adverse outcomes following angiographic procedures in high-risk patients.
Attenuated plaque ≥ 5mm by intravascular ultrasound(IVUS) was reported to be high risk for distal embolism in Acute coronary syndrome(ACS). The purpose of this study is to assess the effect of thrombus aspiration catheter and distal protection device (filter wire; Filtrap™) in the aforementioned subgroup of patients at high risk for distal embolism.
Coagulopathy with transfusion requirements is frequent during cardiac surgery with cardiopulmonary Bypass. Rotational thromboelastrometry (ROTEM®) is a viscoelastic whole blood point of care test used to assess the patient's coagulation status. The purpose of this study is to evaluate the feasibility of ROTEM® analysis in the presence of very high heparin concentrations as seen during cardiopulmonary bypass.
Phase II clinical trial which will include all patients diagnosed with chronic anterior myocardial infarction (more than 6 months from the acute phase and the complete revascularization in which it is assessed the evolution of left ventricular function in patients to the monitoring against their own basal condition. Included patients will be studied in the following conditions: - Basal condition: defined as the immediately preceding to the administration of cell therapy treatment. - Monitoring Condition 1: three months after drug administration of cell therapy. Includes non-invasive methods of exploration of ventricular function. - Monitoring Condition 2: six months after administration of treatment. Includes the same methods of exploration of ventricular function practised in the basal condition, including cardiac catheterism as well as non invasive methods. - Monitoring Condition 3: twelve months after administration of the cell therapy drug. Includes non-invasive methods of exploration of ventricular function. The trial hypothesis we propose consists of mononuclear cells of bone marrow providing progenitor cells with regenerative capacity and also secreting several angiogenic factors, and their implantation into ischemic tissues should contribute with both elements to the angiogenesis and tissue regeneration with myocardial functional recovery
Coronary artery disease (CAD) is the most common cause of death and a major cause of hospital admissions for acute chest pain. In spite of improved treatments still many patients with CAD have daily attacks of severe chest pain and severely reduced life quality. The investigators have established a double-blind placebo-controlled trial in patients with CAD to test efficacy and safety of treatment with adipose derived stem cells to improve perfusion in the heart muscle and exercise capacity, and reduce the patient's symptoms.
The purpose of this study is to examine the effectiveness of a Psychodynamic Motivation and Training Program (PMT) for the improvement of physical fitness in patients with stable coronary heart disease as compared to advice in exercise training or treatment as usual.
Recent clinical trials demonstrated that virtual histology-intravascular ultrasound (VH-IVUS) is a useful test predicting clinical outcomes of the coronary artery disease (CAD). Thin cap fibroatheroma (VH-TCFA) was proposed a predictor of cardiovascular event by VH-IVUS combined with more than 70% plaque burden and less than 4mm² minimal lumen area (MLA) by IVUS. Fractional flow reserve (FFR) is an established index of the physiological significance of a coronary stenosis. Recent large scale trials demonstrated FFR guided PCI showed favorable clinical outcomes. VH-IVUS represents anatomical severity, but FFR represents functional severity of CAD. Few studies reported relevance between two tests. Aim of this study was to investigate whether the geometry and composition of lesions were different under FFR criteria.
Comparison of the cardioprotective effects and safety of two cardioplegic solutions (solutions used during a cardiac arrest in the heart surgery) in patients undergoing cardiopulmonary bypass for coronary artery bypass surgery.
The CONFIRM study was developed to examine the prognostic value of cardiac computed tomographic angiography (CCTA) findings for prediction of future adverse cardiac events related to coronary artery disease (CAD) in a large, international patient population. The purpose of this multicenter registry is to correlate coronary and non-coronary cardiac findings by CCTA with demographic and clinical data for refinement of risk stratification of individuals with suspected or known CAD.
Coronary artery stents have improved the safety and efficacy of percutaneous coronary intervention for coronary artery disease. Drug-eluting stents have been shown to decrease neointimal hyperplasia and to reduce the rate of restenosis and target-lesion revascularization as compared to bare-metal stents. Drug-eluting stents consist of a metallic platform and a therapeutic substance that is usually released from a polymer matrix. A previous study utilizing a bioresorbable polymer has demonstrated a favorable safety and efficacy profile in a large-scale clinical trial as compared to a first-generation druf-eluting stent (LEADERS trial). The objective of the study is to compare the safety and efficacy of a sirolimus-eluting stent with a biodegradable polymer with an everolimus-eluting stent with a durable polymer in a prospective multicenter randomized controlled non-inferiority trial in patients undergoing percutaneous coronary intervention in routine clinical practice.
