Active clinical trials for "Angina Pectoris"

The purpose of the study is to determine whether administration of 150 mg clopidogrel is effective in reducing the one-year incidence of thromboischemic events in patients with high on-clopidogrel platelet reactivity compared to 75 mg clopidogrel after elective percutaneous coronary intervention.

Drug eluting stents (DES) are widely used for treatment of coronary artery lesions. The Xience Sierra stent has a refined design of the metal stent backbone and is used in patients with various clinical syndromes and in different lesions. Clinical outcome of patients with previously unknown (silent) diabetes and prediabetes is of increasing interest since the latter group has recently shown to be associated with a significant risk of adverse cardiovascular events after treatment with contemporary DES. Outcome data in a population of high-risk all-comer patients, including many patients with diabetes mellitus and prediabetes, would be of great interest, but such data are not available yet. In addition, there is a lack of data in a general all-comer population. Therefore, the COASTLINE study will primarily assess the safety and efficacy of the Xience Sierra stent in a general all-comer population as well as a high-risk all-comer population.

The purpose of this study is to evaluate the effect of febuxostat, once daily (QD), compared to placebo as an add on to stable anti-anginal therapy, on the total exercise time of participants with Chronic Stable Angina.

The purpose of this study is to determine whether a single intracoronary infusion of Ad5FGF-4, delivered during induced transient ischemia, is effective in improving myocardial perfusion, angina functional class, patient symptoms, and quality of life. Short-term (8 weeks) and long-term (12 month) safety of Ad5FGF-4 will also be evaluated. The primary endpoint is change in adenosine triphosphate (ATP) stress SPECT reperfusion defect size.

Randomised trial of Spinal Cord Stimulation (SCS) and Percutaneous Myocardial Laser Revascularisation (PMR) in patients with Refractory Angina Pectoris. Hypothesis: difference in exercise tolerance at 12 months between SCS and PMR

This RCT aims to determine if it is possible to perform acupuncture on men and women diagnosed with stable angina who have symptoms, chest pain, and/or chest discomfort. The investigators want to determine if acupuncture reduces the pain and other symptoms of angina, chest pain, and chest discomfort. The investigators also want to examine whether this study is acceptable to the participants, and by carrying out this study the investigators will be able to tell how many participants they will need in a future larger study to further test acupuncture to reduce the symptoms of angina in women.

Prospective, randomized, non-inferiority, multicenter, international study.In total 4000 patients (70 centers in Europe) with de novo lesions in native coronary arteries who meet the eligibility criteria randomized to 6 versus 12 month dual antiplatelet therapies following a second generation DES implantation. Assuming that the true proportion of thrombotic events is equal to 2.3% for both regimens (6-month and 12-month clopidogrel) 2000 patients for each treatment group are necessary to demonstrate a non-inferiority of the 6-months regimen if the proportion of thrombotic events will be no more than 3.5% with a power of 0.80 and a significance level of 0.05 (one-tail). If the non-inferiority hypothesis will be rejected, the superiority hypothesis (12-months regimen is superior to the 6-months-regimen) will be tested at a significance level of 0.05 (two-tails). The maximal not clinically relevant difference for the non-inferiority hypothesis of 1.2 % more thrombotic events has to be considered together with the lower expected number of bleeding events in the 6-months regimen. All the analysis will be done as "intention-to-treat" analysis.

We wish to see if the drug rosiglitazone, currently used in the treatment of type 2 diabetes, could be used as a new treatment for angina when compared with placebo in overweight subjects who do not have overt diabetes. The drug will be given for 3 months and the subjects will be have their angina tested, by way of exercise testing, angina quality of life questionnaire and 24-hour ECG monitoring before and after using the drug.

Use of high loading doses of clopidogrel (antiplatelet drug) just before coronary interventions is associated with improved outcomes after coronary stenting. However the onset of platelet inhibition after clopidogrel loading takes 2 to 4 hours and its action if very variable. A way to overcome this limitation is loading with a more potent antiplatelet drug such as prasugrel. Therefore in the current study the investigators want to compare loading with 60 mg prasugrel (potent antiplatelet drug) and loading with clopidogrel (standard drug) in patients undergoing elective coronary intervention.

This is a multicentric randomized comparison between paclitaxel-coated balloon angioplasty or paclitaxel-eluting stent implantation in patients with stable or unstable angina with the evaluation of restenosis by Quantitative Coronary Analysis.
