Filter by:The zotarolimus-eluting Endeavor Resolute stent is not inferior to the everolimus- eluting Xience V stent platform regarding a composite of cardiac death, myocardial infarction or target lesion revascularisation in a real-world population.
We sought to determine whether the dual-source computed tomography assessment of aortic valve stenosis and coronary artery disease is equivalent to or even better than conventional invasive coronary angiography and transthoracic echocardiography.
The purpose of this research is to determine if two proteins in the blood are increased during acute myocardial infarction and whether their levels are higher in those who develop heart failure than those who do not. These two proteins are produced and potentially released when the heart muscle is damaged. They may then be released into the blood and be detected by standard method in the research laboratory. At this time, detection of an increase in these proteins in the blood is not known to be associated with any disease or myocardial infarction.
Construction of coronary heart disease cohort of more than 10000 patients in China. Investigation on current situation of secondary prevention of CHD will be carried out and the effect of physician training and patient education will be evaluated.
Blood samples and health information (e.g., age at diagnosis, test results) are collected for the purposes of genetic research. The blood samples are assigned a number and stored in a repository for safe keeping until they are needed for a research project. Participants are persons who are healthy (not having high blood pressure, diabetes, or high cholesterol levels) or persons who have Coronary Artery Disease (CAD) and live in Indiana. Participants complete a questionnaire at the time the blood sample is drawn and are contacted once a year to update their health history. Researchers apply to the Fairbanks Institute for use of the blood samples and health information minus participant names and contact information. Their research is required to be related to find genes or substances made by genes that may be involved in Coronary Artery Disease with the purpose of improving the investigators understanding of the illness potentially leading to the development of new diagnostic tools for identifying the illness, new treatments,or preventative measures. This study will be repeated for other disorders like Diabetes and Cancer.
Subjects with impaired glucose tolerance will be randomized to either rosiglitazone or placebo for a 18 month period. The study will look at baseline, 12 month and 18 month data for exercise tolerance, coronary artery calcification and diabetes indicators.
The purpose of this study is to determine whether polymorphisms in G protein subunits, namely Galphas and Galphaq, are associated with altered cardiac performance in heart failure patients.
The purpose of this study is to determine whether therapeutic intervention on impaired glucose tolerance in patients with coronary heart disease can decrease the incidence of new onset DM.
Increasing lesion complexity in percutaneous coronary interventions (PCI) has warranted the use of overlapping drug-eluting stents. Whether the substantial impairment of arterial healing observed at sites of overlap in preclinical pathologic studies persists in patients undergoing PCI is unknown. Consecutive patients with long lesions in native coronary vessels requiring stents in overlap are prospectively randomized to receive multiple sirolimus-,paclitaxel polymer-or zotarolimus eluting stents versus bare metal stents. The completeness of stent struts coverage and/or late malapposition are evaluated by Optical Coherence Tomography at 6 months follow-up
The main objective of this study is to assess the safety and effectiveness of the TiN-coated MAR-Tyn stent in maintaining minimum lumen diameter in de novo native coronary artery lesions as compared to an uncoated control cobalt-chromium balloon-expandable stent (Vision, Abbott Vascular). Both stents are mounted on a Rapid Exchange Stent Delivery System.
