Active clinical trials for "Coronary 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.

Study of heterogeneity in associations between social deprivation and the initial presentation of 12 cardiovascular diseases.

The main purpose of this study is to observe the incidence of major adverse cardiac and cerebrovascular events (MACCE), target vessel failure (TVF), target vessel revascularization (TVR) and stent thrombosis out to 5 years after the procedure in patients who underwent percutaneous coronary intervention (PCI) with everolimus-eluting stents for unprotected left main coronary artery (ULMCA) disease and lesions involving the ULMCA in Japan. The investigators will also establish a method of adjustment to the Japanese version of the SYNTAX score by conducting an assessment using the SYNTAX score recently reported in the US and Europe as well as the EuroSCORE, and by clarifying the differences of PCI procedures and treatment results in Japan with those reported in the US and Europe.

The rationale of the present clinical trial is to study whether an invasive strategy in clinical stable patients over 80 years with NSTEMI/UAP may improve rates of death, reinfarction, stroke, need of urgent revascularisation, myocardial function and quality of life. The invasive approach involves coronary angiography with immediate evaluation for three different treatment options; 1. Percutaneous coronary intervention (PCI), 2. Coronary artery bypass graft (CABG) or 3. medical treatment. Clinical practice shows that older patients are commonly treated less vigorously than younger patients and the present guidelines are based on a considerably younger population.

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.

It is the aim of the multi-centric and prospective registry to analyze in patients with CAD the impact of different grades of renal failure on the outcome and course of the patients and to correlate these with clinical variables. In particular, the registry has the following objectives: prospective consecutive assessment of all patients with coronary artery disease and renal failure in the participating hospitals of the registry evaluation of the outcome and course of patients with regard to their different stages of renal failure at baseline analysis of the impact of different therapeutic strategies on acute and long-term outcomes identification of clinical risk factors, novel biomarkers and genetic markers for an unfavorable long-term outcome

This will be a registry study that will enroll patients referred for an ECG treadmill test with nuclear myocardial perfusion imaging (MPI). The high frequency QRS (HFQRS) information will be recorded and analyzed automatically and simultaneous with the standard ECG signals by the HyperQ System. Results of subsequent tests performed on each patient will be collected and used to enhance the reliability of designating each patient as a CAD-negative (i.e., no significant coronary artery disease) or a CAD-positive (i.e., significant coronary artery disease).

The purpose of the investigation is to verify the efficiency of the HyperQ™ system in detecting exercise induced ischemia, with higher specificity and sensitivity than conventional ECG Stress testing. The study will be carried out by applying the HyperQ™ system during cycle ergometer stress testing in patients who are referred for angiography at the Department of Cardiology, Essen University Hospital, Essen, Germany. The HyperQ™ results will then be compared to the standard ECG stress test results using the angiography results as the gold standard. The study will be considered successful if analysis of the HyperQ provides a statistically significant improvement over the diagnostic accuracy of conventional ECG stress testing analysis.

Genetic studies of coronary artery disease, restenosis after angioplasty or stenting, focusing on renin-angiotensin system genes and adiponectin gene, and their interactions.

Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.
