Active clinical trials for "Coronary Disease"

Gingival inflammation has been associated with cardiovascular diseases, including heart attack and stroke, because of elevation of blood risk markers such as cholesterol, glucose and C reactive protein. The treatment of gingival diseases decreases the concentration of these risk factors in the blood of cardiovascular patients.

In this study, typical cases of blood stasis syndrome of coronary heart disease are selected, by using microRNA chip, cDNA microarray and other bioinformatics technologies to filter and verify related miRNA and its target gene of Coronary Heart disease. Meanwhile, intervene by Xuesaitong soft capsules to investigate related miRNA and its target gene of Coronary Heart disease.

Cardiovascular complications account for the highest mortality in type 2 diabetic patients, mainly due to coronary artery disease (CAD). Most of the attention in treating CAD in type 2 diabetes is understandably directed toward treating coronary artery conditions. However there are other treatable culprits in these patients. Left ventricular hypertrophy (LVH) is widespread in type 2 diabetic patients with CAD, even in the absence of hypertension. It is a strong predictor of cardiovascular events and all-cause mortality. Regression of LVH has been associated with an improved prognosis, independent of change in blood pressure (BP). Therefore, cardiovascular events and mortality in type 2 diabetes with CAD might will be reduced if the investigators can find novel therapies to regress LVH. Alpha-lipoic acid reduces oxidative stress which then regresses LVH. Alpha-lipoic acid can improve endothelial function in diabetic conditions. Hence, the main aim of this study was to assess whether alpha-lipoic acid could regress LVM in type 2 diabetic patients with CAD.

The aim of this study is to investigate usefulness of the respirophasic variation in carotid artery peak flow velocity measured by Doppler ultrasound, which is noninvasive and easily accessible, as a predictor of fluid responsiveness in patients with coronary artery disease.

This study is being done to determine if Ranolazine treatment improves coronary microcirculation function among patients with coronary microcirculation dysfunction. We are also looking to learn if symptomatic improvement of chest pain during treatment with Ranalozine is related to improved coronary microcirculation function.

The recently introduced Computed tomography (CT) scanner, Discovery CT750 HD (GE Healthcare, Milwaukee), incorporates a battery of innovations aimed at improving diagnostic image quality, evaluating perfusion and assessing for scar, in an effort to address the current shortcomings of Computed tomographic coronary angiography (CTCA) in patients with significant coronary artery disease. The new scanner will use a novel method of scanning (Cardiac Gemstone Spectral Imaging - Cardiac GSI) and image reconstruction (Adaptive Statistical Iterative Reconstruction- ASIR) as opposed to standard definition 64-slice CT Multi-detector row computed tomography(MDCT)and Filtered Back Projection (FBP) used by the conventional CT scanners. The Cardiac GSI protocol enables the scanner to acquire images at two different x-ray energies almost simultaneously, which can be post-processed to selectively reduce beam hardening artefacts and delete materials with specific attenuating properties from the images, such as coronary calcium. ASIR offsets the potential increase in radiation dose required for Cardiac GSI scanning. This will potentially result in images of higher diagnostic quality with an equivalent or perhaps lower dose of radiation compared to present technology. Furthermore, it is hypothesised that dual-energy acquisition may improve the accuracy of the assessment of perfusion. Although initial in-vitro results are encouraging, this technology has not been rigorously assessed with regards to its feasibility and diagnostic quality, limiting its applicability in routine clinical practice. This assessment will require a trial comparing the accuracy of Cardiac GSI CTCA with that of Invasive coronary angiography (ICA) for anatomical assessment of stenosis, Myocardial Perfusion Imaging with Single Photon Emission Computed Tomography (MPI-SPECT) for assessment of perfusion and Cardiac Magnetic Resonance (CMR) for assessment of myocardial scar. We have designed a pilot study in this regard which will help us assess the feasibility of the scan protocol and provide data to power a larger study to assess the diagnostic remit of Cardiac GSI scanning in the assessment of patients with high-risk of significant coronary artery disease and myocardial scar.

The aim of the study is to test the accuracy of Regadenoson to induce maximal and steady state hyperemia as compared to central venous infusion of adenosine for assessing fractional flow reserve. (adenosine is considered to be the gold standard)and to investigate the time intervals of maximum hyperemia induced by centrally and peripherally administered Regadenoson.

Participants being evaluated for suspected or known Coronary artery Disease (CAD) based on signs and/or symptoms, will be invited to participate in the study. The duration for a participant in the study may range from 2 days to 4-6 weeks. One to four visits to the study doctor will be required. This study will investigate the diagnostic results of gadobutrol-enhanced Cardiac Magnetic Resonance Imaging (CMRI) images regarding the detection (sensitivity) and exclusion (specificity) of coronary artery disease utilizing a uniform image acquisition software. The CMR images will be tested either against the results from routine clinical Coronary Angiography (CA) or those from Computed Tomography Angiography (CTA), which is used as the standard of reference. The CA/CTA may have been performed up to 4 weeks prior to enrollment or be scheduled up to 4/6 weeks after the study. CMRI and CA/CTA images will be collected for an independent image review (blinded read).

The objective of the INCORPORATE trial is to evaluate whether an intentional invasive strategy with ischemia targeted, reasonably complete coronary revascularization and optimal medical therapy is superior as compared to a primary conservative approach and optimal medical therapy alone in terms of spontaneous myocardial infarct-free and overall survival in patients with severe peripheral artery disease, underwent peripheral artery revascularization due to critical limb ischemia. The INCORPORATE trial is designed to be non-blinded, open-label, prospective 1:1 randomized controlled multicentric trial.

To compare the MT005 (MiStent) with the XIENCE with respect to target lesion failure (TLF) at 12 months in a non-inferiority trial in a "real world" patient population and to confirm that the domestic extrapolation of the DESSOLVE III study results is valid.
