Active clinical trials for "Angina, Stable"

The purpose of this study is to determine if MR Perfusion Imaging is non-inferior to coronary angiography with measurement of Fractional Flow Reserve (FFR) in guiding management of patients with stable chest pain. All patients will undergo an MR Perfusion Imaging test. Further management will be guided by the result of the cardiac MRI in half of the patients (chosen by random). The other half will undergo coronary angiography with measurement of FFR. The result of this test alone will guide their further management. The result of the initial MR Perfusion test will not be available to the treating doctors of this group. All patients will receive optimal medical therapy (OMT) All patients will undergo follow-up to find out if they have any relevant heart related events.

The purpose of this study is to assess the usability and safety of the Opsens OptoWire and Optomonitor in measuring fractional flow reserve (FFR) in patients with coronary artery disease who are undergoing a coronary angiogram.

Multi-center, randomized-controlled trial comparing a comprehensive cardiac CT protocol with standard stress testing in patients with stable chest pain complaints.

The purpose of this study is to evaluate the effect of vitamin E on preventing from incidence of contrast induced acute kidney injury (CI-AKI) in the patients who undergone coronary angiography.

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.

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.

The aim of this study was to assess the amount of additive value of HS-CRP levels to a positive exercise tolerance test (ETT) in predicting coronary artery disease (CAD) using coronary angiography as the gold standard. The investigators concluded that HS-CRP can be used as a single predictor of coronary vessel involvement in patients with stable angina and positive ETT.

Influenza vaccine reduces the cardiovascular events in post-myocardial infarction (MI) patients and in those with stable angina (SA).

This study wishes to understand: whether vaccination against influenza in coronary artery disease (myocardial infarction and stable angina) patients is as effective as it is in healthy subjects; whether vaccination really decreases the episodes of influenza infection in those coronary artery disease patients who receive the vaccine than those who do not.

Angina is form of chest pain that is due to a lack of blood to the heart muscle. Angina is commonly triggered by stress and exertion, and is a common health problem worldwide. The diagnosis and treatment of angina is usually focused on detection of blockages in heart arteries, and relief of this problem with drugs, stents or bypass surgery. However, about one third of all invasive angiograms that are performed in patients with angina do not reveal any blockages. Many of such patients may have symptoms due to narrowings in the very small micro vessels (too small to be seen on an angiogram). The purpose of this research is to undertake a 'proof-of-concept' clinical trial to gather information as to whether routine tests of small vessel function in the heart might help identify patients with a stable coronary syndrome due to a disorder of coronary function (vasospastic or microvascular angina), and appropriately rule out this problem in patients with normal test results. The diagnostic strategy enables stratification of patient sub-groups to optimized therapy (personalised medicine). Evidence of patient benefits in this study would support the plan for a larger study that would be designed to impact on healthcare costs and patient reported outcome measures (PROMS).
