Active clinical trials for "Coronary Artery Disease"

correlation between EFT volume measured by Cardiac MRI and the angiographic severity of coronary artery disease (Syntax Score) in diabetic vs non diabetic CAD population and detect if there is a cut off value for each group that could predict higher risk.

Hypothesis: the clinical outcome of patients with indication of PCI and coronary stent implantation that are at high risk of events can be improved with a widespread use of intra-coronary tools that allow a PCI optimization (i.e. functional assessment by pressure guidewire and intra-coronary imaging techniques). Objective: to evaluate whether the use of pressure guidewire and intra-coronary imaging techniques (mainly optimal coherence tomography) in patients at high risk of events undergoing coronary angiography for myocardial revascularization is associated with an improved clinical outcome in comparison with patient with angiographic alone guided cobalt-chromium everolimus-eluting coronary stenting. Methods: Prospective observational multicentric international study with a follow-up of 12 months, including 1.000 patients in 40 sites located in 3 European countries (Spain, France, and Portugal). The control group will be comprised by a similar number of matched patients included in the "extended-risk" cohort of the XIENCE V USA study. PCI will be performed following local standard protocols and accordingly to the physician criteria. The use of pressure guidewire will be recommended according to the current guidelines, in patients with angiographically intermediate lesions and in those with multivessel disease. The use of OCT will be strongly recommended, as patients included will be considered to be at high risk of events, accordingly to the current recommendations. The primary endpoint will be target lesion failure (TLF) at 1 year.

In-hospital mortality after cardiac surgery ranges from 2-6%. Many patients suffer from major adverse cardiovascular events (MACE) which results in impaired disability-free survival. Troponin plays the central role in identifying MACE. However, interpretation after cardiac surgery is difficult due to ischemia-reperfusion-injury and direct surgical trauma. While the 4th universal definition of type 5 myocardial infarction uses the 10 x ULN as cut-off, >90% of patients after on-pump procedures exceed this cut-off. Clinical consequences are unclear. The dynamic of Copeptin and Heart-type fatty acid binding protein (H-FABP) concentrations starts very early, i.e. several hours before Troponin. The investigators plan a prospective multicenter cohort study to evaluate 1) the independent association between Copeptin and H-FABP with disability -free survival and MACE after cardiac surgery; 2) the predictive gain of their addition to the Euroscore II; 3) the independent association between H-FABP and acute kidney injury.

The purpose of this Registry is creating a database management that allows continuous monitoring characteristics, evolution, prognostic indicators and management of patients undergoing coronary angioplasty in Portuguese Hospitals, and identify the appropriateness of clinical and interventional practice recommendations for diagnosis and treatment of coronary disease and monitoring its evolution.

The primary objective of this feasibility study is to determine whether it is possible to conduct a study of the ClearView scan among patients under evaluation for acute cardiovascular events, as well as give insight into the performance of the ClearView scoring algorithm with respect to this patient population. The EPIC™ scan is a bio-electrographic tool that may assist the health care provider in rapid assessment of the systemic origin of the patient's presenting symptom(s). The EPIC ClearView is a potentially valuable resource that may benefit an emergency department (ED) by offering expedited "chest pain" etiologic differentiation capabilities. The subsequent results have the potential to include more rapid "chest pain" patient diagnosis and appropriate disposition of non-cardiac chest pain (rule out MI); optimized precious resource expenditure (nursing, physician, inpatient or observation bed, etc.); lower costs to facility, patient and insurance company; and greater patient satisfaction rates due to decreased ED wait time.

The PROMUS Element™ clinical trial (PLATINUM-PLUS) consists of a randomized controlled trial (RCT) in the European Union (EU) which will enroll approximately 2980 subjects (2:1 randomization PROMUS Element™: Xience™ Prime) in a Population of consecutive, all comers in the reimbursed indications per-country All subjects will be screened per the protocol required inclusion/exclusion criteria.

To evaluate the prognostic value of coronary CT angiography (CCTA) for risk stratification in asymptomatic adults in comparison with conventional risk stratification (CRS) and coronary artery calcium scoring (CACS).

Development of myocardial ischemia, and/or myocarditis would induce different changes in myocardial contraction behavior pattern,which maybe very subtle, and may not be detected by the 2D and m-mode echocardiography examinations. According to tissue Doppler imaging(TDI), they can be depicted by different models of echo with higher frame rates. In addition, many studies using TDI have significantly contributed of efforts to evaluate systolic and diastolic function and prognosis. This study assess the value of the indices of left ventricular function obtained by using TDI in patient with coronary artery disease(CAD). We hypothesized that TDI will add incremental value for regional wall motion abnormality of CAD and its prognosis.

This study is for people who have a SPECT scan (nuclear imaging of the blood flow to the heart muscle) ordered by their medical doctors. As part of the SPECT scan, they will have been given a drug called regadenoson to widen and expand the blood vessels bringing blood to the heart muscle. The SPECT pictures of the heart are taken about an hour after the regadenoson is put into an arm vein through an IV. In this study, additional echo pictures will be taken and compared to the SPECT pictures. The aim of the study is to see if the echo pictures work as well as SPECT to measure the blood flow to the heart muscle.

The RITMO (Registro Italiano sul trattamento del Tronco coMune non protettO) observational study will appraise the prevalence, management strategy, and prognosis of unprotected left main coronary artery disease in Italy.
