Filter by:Drug-eluting stents effectively reduce restenosis but may increase late thrombosis and delayed restenosis. Persistent polymer could be responsible. Local delivery of paclitxel from a polymer-free Yinyi stent (Dalian Yinyi biomaterial research and development co.ltd) may prevent these complications.

Sirolimus-eluting stent (SES) has been world-widely used in clinical practice in treating patients with coronary artery disease (CAD). The efficacy and safety of Excel SES (JW Medical, Shandong, China, MA) with biodegradable polymer has been proved by several clinical trials. Here the investigators design a prospective, multicenter, randomized clinical study in purpose of identifying the non-inferiority in the efficacy and safety in treating CAD patients by Firebird 2 SES (Microport, Shanghai) with durable polymer, comparing with Excel SES.
Subjects will be consented to the study prior to Coronary Artery Bypass Graft (CABG) and randomly assigned to receive either ticagrelor 90 mg bid or placebo bid starting within 48 hours of surgery. Subjects will remain on study drug for a minimum of 12 months during which time they will receive telephone follow-up one and nine months following CABG and clinic visits three, six, and twelve months following CABG.
GLP-1 has not only beneficial effects on glucose metabolism but also direct positive effects on cardiac function and metabolism in both experimental models and in patients with type 2 diabetes mellitus. Clinical data on the effects of GLP-1 agonists on cardiac function and glucose control in patients undergoing cardiac surgery are not known. Based on the results of experimental studies there is a potential for exenatide to positively influence both cardiac function and glucose metabolism in cardiac surgery patients with and without type 2 diabetes mellitus. The primary endpoint of this study is to examine whether pre- and peri-operative administration of exenatide affects perioperative hemodynamics, echocardiographic parameters, necessity of antiarrhythmic and inotropic treatment and glucose control in patients with coronary atherosclerosis and decreased left ventricular function undergoing elective coronary artery bypass grafting operation (CABG). In addition, safety and tolerability of peri-operative administration of exenatide in these patients will be examined as a secondary study objective.
The present study is to determine the ability of urinary total adiponectin and its isoforms excretion in the prediction of contrast induced nephropathy (CIN) in the patients undergoing PCI.
Thrombotic event is one of the most serious complications of coronary artery disease, which often result in myocardial infarction and even death. Even according to the standard guidelines for antiplatelet therapy, there are still 6% to 15% of patients occur thrombotic events, in high-risk patients, the proportion is higher, this phenomenon is called anti-platelet drug resistance in clinical practice The aim of this multicenter prospective, randomized, controlled study is to observed policosanol on aspirin or clopidogrel resistance in patients with platelet aggregation after Percutaneous Coronary Stent Implantation (PCI) and occurrence of platelet aggregation and short-term prognosis to find new ways to the prevention of platelet aggregation .
Blockage of the heart arteries (coronary artery disease) can lead to angina (chest pain), heart attacks, heart failure, and/or death. Positron emission tomography (PET) stress myocardial perfusion imaging (MPI) is a powerful tool to help identify blockages in the coronary arteries. During the PET MPI test, a drug is given to mimic the effects of exercise on the heart. The study was done to measure blood flow to the heart using two similar drugs approved to mimic the effects of exercise on the heart in people during a heart stress test. The first drug, called adenosine, has been approved for this use for several decades. The second drug, called regadenoson, was approved in 2008. The investigators were looking at whether the increase in blood flow to the heart with the newer drug (regadenoson) was similar to the increase in blood flow with the older drug (adenosine). This information is important for the use of these drugs in patients and for interpreting the blood flow values.
Since 2007, the cost of sequencing a diploid human genome has fallen dramatically, from approximately $70 million to $20,000. As affordable sequencing platforms become more widely available, the advancement of biomedical science will draw increasingly on whole genome sequencing research requiring large cohorts of diverse populations. Key policy, ethical and legal implications of these developments will need to be understood in order to promote the efficacy and effectiveness of genomic research going forward. An overall aim of this project is to obtain feedback on the informed consent process from some of the earliest particpants in studies using whole genome sequencing. A more specific goal is to characterize the salient personal and public references accessed by participants around the time of the informed consent process. By highlighting trends in participants views about study participation around the time of the initial informed consent process, we aim to advance the development of an ethically and socially relevant vocabulary with which to negotiate future terms of use for personal sequence data in genomic research. Participants will be asked to complete a one-time, semi-structured telephone interview lasting approximately 45 minutes in the period 2-8 weeks following their initial informed consent session at the NIH. They will be recruited from two NIH protocols employing whole genome sequencing for distinct purposes. They The ClinSeqTM Study is a large-scale medical sequencing project investigating the causal role of genetics in cardiovascular disease enrolling both symptomatic and healthy individuals. The Whole Genome Medical Sequencing for Gene Discovery Study (WGMS) enrolls children and adults for full sequencing with the aim of discovering the genetic etiology of rare conditions.
Kryptonite is a non-toxic biologic polymer, that has previously been used in orthopedic surgery. The objective of our study is to demonstrate the benefits of Kryptonite in cardiac surgery patients at high risk for sternal wound complications. The investigators have designed a randomized clinical trial of 48 high risk patients, with a 1:2 randomization of kryptonite to conventional closure. The primary outcome will be quality of life. Secondary outcomes include sternal complications, pain, hospital length of stay, and respiratory function.
