Filter by:The primary hypothesis is that computed tomography (CT) is superior to invasive coronary angiography (ICA) concerning the primary endpoint MACE (MACE = major adverse cardiovascular event; defined as at least one of the following: cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke) after a maximum follow-up of 4 years, in other words, that CT will result in a significantly lower rate of MACE. Secondary outcomes include MICE (MICE = minor cardiovascular events), procedural complications, cost-effectiveness, radiation exposure, cross-over to CT or ICA, gender differences, and health-related quality of life.
The investigators propose to correlate 1) cardiac MRI pericardial adipose volume, 2) the presence of pericardial monocytes and 3) circulating immune biomarkers in persons with and without CHD and HIV infection compared to seronegative controls with known CHD. The investigators aim to test the hypothesis that higher amounts of pericardial fat deposition and increased presence of monocytes within this adipose tissue are associated with underlying coronary artery disease in persons with HIV infection as measured by cardiac MRI.
Biomime stent is a novel sirolimus-eluting stent (SES) (Meril Life Sciences Pvt. Ltd., Gujarat, India) with an ultra-thin stent platform (65 μm) and a biodegradable polymer licensed for the treatment of de novo coronary lesions. However no data regarding the efficacy and safety of this stent in an "all-comers" patient population treated with percutaneus coronary interventions (PCI) have been published so far. In this registry the investigators aimed to collect clinical and angiographic information about an extensive "all-comers" employ of this novel stent.
The purpose of this study is to collect data from real-world use with the Glider Percutaneous Transluminal Coronary Angioplasty (PTCA) Balloon Catheter to support the effectiveness of the Glider PTCA Balloon for crossing into complex coronary lesions.
Currently, cardiac computed tomography angiography (CCTA) is a well-implemented non-invasive diagnostic imaging modality in patients with stable chest pain. Besides conventional CT-reading, CCTA is also capable to identify several morphologic and geometric characteristics of atherosclerotic plaques. Recently, the investigators showed that the use of semi-automated plaque quantification algorithm identified parameters predictive for acute coronary syndrome on top of clinical risk profiling and conventional CT-reading. In addition, several atherotrombosis biomarkers, like high-sensitivity cardiac troponins, are described as related to coronary artery disease and cardiovascular events. Prospective data with sequential analysis of atherosclerotic plaques combined with different atherothrombosis biomarkers are currently lacking, but will provide important clues about the pathophysiology of plaque progression and atherothrombosis.
Thus, the purpose of the present study was to evaluate the effects of continuos exercise training (CET) and interval exercise trainining (IET) on oxygen uptake efficiency slope (OUES) in patients with coronary artery disease.
In this study, the investigators will determine whether patients with documented atherosclerosis are characterized by specific epigenetic changes in circulating cells of the innate immune system, compared to patients without atherosclerosis.
The objective of this study is to assess the safety and efficacy of the Orsiro Sirolimus Eluting Coronary Stent System in the treatment of subjects with up to three native de novo or restenotic (standard PTCA only) coronary artery lesions compared to the Xience coronary stent system.
Anticoagulation with heparin is indicated in several situations, such as acute coronary disease (in combination with antiplatelet therapy) for the prevention and treatment of venous thromboembolism and situations with high risk of thromboembolism. Recently, the latest trials on anticoagulation for stroke prevention on atrial fibrillation have shown an increased risk for acute mycardial infarction on patients submitted to new oral anticoagulants, such as dabigatran. The mechanism is still unclear, however, in this context, some previous studies about interaction between anticoagulants ( mainly heparin) and platelet aggregation have shown conflicting results: while some suggest an inhibitory effect of heparin on platelet function, others suggest that heparin could promote an increase in platelet activation. The present study aims to assess the effects of the LMWH Enoxaparin and direct thrombin inhibitor, Dabigatran, on platelet aggregation, studied and compared by different methods in patients with chronic coronary artery disease (CAD).
The main focus of the pilot study is to evaluate the feasability and effectiveness of a collaborative care intervention for patients suffering from a coronary heart disease (CHD) with insufficient controlled health related risk factors in their lifestyle. The design of the study is a wait list control design. 30 patients will receive treatment immediately after submission, the other 30 after 6 months. An interdisciplinary team, including a care manager for each patient, will offer an individualized treatment plan, based on shared decision making for each patient to reduce risk factors and improve quality of life.
