Filter by:The purpose of this study is to determine if a new drug, varenicline, for smoking cessation is more effective than the standard nicotine replacement therapy aide currently used, "the patch" among smokers hospitalized with coronary heart disease.
Current guidelines recommend the addition of proton pump inhibitors (PPI) to patients taking double anti-platelet therapy (Aspirin and Clopidogrel) to prevent upper GI bleeding1. Many post percutaneous coronary intervention (PCI) patients are treated with dual anti-platelet medications as well as PPI to prevent upper GI bleeding. Recently, it was shown that PPI interact with the P450 system in the liver and reduce the platelet inhibitory effect of Clopidogrel2,3. Clopidogrel is activated by CYP2C19, which also metabolizes PPI4. Furthermore, a recent article showed increased mortality in patients taking PPI and clopidogrel compared with patients taking clopidogrel without PPI protection5. The degree of reduction in the platelet inhibitory properties of clopidogrel might vary among the different PPI4. The use of PPI for GI protection in patients treated with dual anti-platelet therapy is not based on randomized trials, but rather on expert opinion. Since H2 blockers are also effective in preventing acid secretion and are not known to interact with the P450 system that affects clopidogrel, the investigators hypothesized that these group of drugs will not interfere with the positive antiplatelet effects of clopidogrel and therefore will offer a good alternative treatment option.
The purpose of this study is to compare the efficacy and tolerability between clopidogrel resinate and clopidogrel bisulfate in patients with coronary heart disease (CHD) or CHD equivalents.
The purpose of this study in humans with stable coronary artery disease (CAD) treatable by PCI (percutaneous coronary intervention) is to evaluate if dynamic physical exercise leads to an instantaneous improvement of coronary collateral function.
The real impact of cardiac surgery and coronary angioplasty remains to be clarified and, where appropriate, the influencing factors in a way beneficial or deleterious remain to be identified. The identification of such factors could make even faster screening, prevention and therefore open therapeutic prospects for those patients. The objective of the study is to constitute a prospective cohort to assess the occurrence of cognitive decline after cardiac surgery (200 patients) and coronary angioplasty (200 patients) using the scale Dementia rating scale (DRS) of Mattis. In addition, the investigators will identify factors that influence positively or negatively, the occurrence of such a cognitive decline. The study based on a systematic monitoring of clinical, biological, imaging and pharmacological factors and, to correlate the respective influence of these factors on the incidence of cognitive decline.
Binodenoson (an experimental drug) and adenosine (an FDA-approved drug that is currently used by doctors) are used to increase blood flow to the heart just like when a person exercises on a treadmill. Using imaging techniques, this increased blood flow can help determine if areas of the heart are not getting enough blood and oxygen during exercise. The purpose of the study is to determine if binodenoson is as good as adenosine in determining if there are areas of the heart not getting enough oxygen when blood flow to the heart is increased.

The purpose of this study is to determine whether Ateronon, a nutritional supplement that contains lycopene from tomatoes has a favorable effect on carotid atherosclerosis, lipid levels, and other biomarkers of coronary heart disease. The trial was stopped early due to insufficient financial support from the initial study collaborator, Cambridge Theranostics Ltd. Collected patient data are sufficient for final trial-based analyses to be conducted with financial support from the new study collaborator, CamNutra Ltd. The data will still be analyzed according to the original study aims.
The purpose of this study is to evaluate the diagnostic accuracy of multi-detector computed tomography using 320 detectors for identifying the combination of coronary artery stenosis ≥ 50% and a corresponding myocardium perfusion defect in a patient with suspected coronary artery disease compared with conventional coronary angiography and single photon emission computed tomography myocardium perfusion imaging.
The purpose of this study is to find out if diabetes damages the blood vessels of adolescents with good diabetes control compared to adolescents with less optimal control.
