The aims of the present project are to study possible differences in inflammatory gene expression and protein secretion in various compartments of adipose tissue being exposed during open cardiac surgery in patients with coronary heart disease undergoing coronary artery bypass surgery.
The purpose of this study is to validate a full-automated post-processing software for quantitative perfusion of the myocardium with magnetic resonance imaging.
The purpose of this study is to evaluate the relative effectiveness and safety of Synergy stent compared to other drug eluting stents.
The purpose of this study is to evaluate the relative effectiveness and safety of Ultimaster stent compared to other drug eluting stents.
This study investigates whether an individualized exercise program, including a personal trainer, can improve cardiovascular status quantified with ultrasound to assess coronary flow reserve and other non-invasive techniques. The subjects in the study will be divided into two groups; one group will have a personalized exercise- and nutrition program and the other group will have acess to a gym membership, but no personal trainer.
The aims of the present study are to measure dynamic changes over time in the plasma level of SDF-1α in patients with confirmed diagnoses of AMI, AF and CHF and in so doing: 1. Monitor the plasma level of SDF-1α at the diagnosis, during and after the long term treatment of AMI, AF and CHF. The SDF-1α level of patients is expected to decrease during treatment of the aforementioned conditions. 2. Correlate the plasma level of SDF-1α in relation to clinical, biochemical characteristics of Acute Myocardial Infarction(AMI), Atrial Fibrillation(AF) and Congestive Heart Failure (CHF). In so doing, the investigators expect that SDF-1α will correlate with the severity of heart disease. 3. Study the dynamic of SDF-1α pertaining to its property as prognostic indicator for the long term follow up risk of readmission and mortality of patients diagnosed with AMI, AF or CHF.
PIONEER-II OPC trial is a prospective, multicenter, single-arm registry trial. 1000 subjects from approximately 40 interventional cardiology centers will be enrolled to evaluate the target lesion failure(TLF) as the primary endpoint at 1 year. And all the subjects will be followed up to 5 years to attain the data of the secondary endpoints.
PIONEER-II RCT trial is a prospective, multicenter, randomized, non-inferiority registry trial. 539 subjects from about 40 interventional cardiology centers in China will be enrolled to evaluate In-stent late lumen loss(LLL) as the primary endpoint at 9 months. And all the subjects will be followed up to 5 years to attain the data of the secondary endpoints.
Coronary drug-eluting stent (DES) has been launched in China for more than ten years. Although it effectively decreases the overall incidence of re-stenosis, DES cannot inhibit the progression of atherosclerosis plaque outside segments. It was shown that the progression rate of non-target atherosclerosis plaque for patients with DES implantation was 6-10%, which indicated that current secondary prevention for coronary heart disease (CHD) is far from the achievement of ideal conditions. Atherosclerosis has many risk factors based on current CHD guidelines, among which the level of low-density lipoprotein (LDL) is the most concerned one. Large clinical studies on statins were performed in the world during the past 20 years. It was demonstrated in these studies that statins were significant to both primary and secondary preventions of CHD. What's more, the lower of LDL level is reached, the lower incidence of clinical cardiovascular events is achieved. However, cardiovascular events were still not avoidable especially for the secondary prevention of CHD even if the level of LDL was significantly controlled under the recommended range of guidelines by high dosage of statins. It was shown in some recent studies that high loading dosage of statins may effectively control the progression of coronary plaque. However, multiple studies found it was hard to control the progression of all patients of coronary plaque due to individual difference. Currently China Food and Drug Administration (CFDA) has not approved the loading dosage of all statins because of possible high safety issues and confusions about the appropriate application in Chinese patients, as well as economy burden to Chinese patients with high treatment cost. How to evaluate individual progression risk of coronary plaque and enhance risk factors control and the treatment of statins for necessary population, is currently an issue, which should be solved in the diagnosis and treatment of CHD. The inhibition in the progression of atherosclerosis plaque is not absolutely dependent on the decrease of LDL. Large number of studies found other risk factors. For instance, diabetes and chronic kidney diseases may also be associated with the progression of plaque. However, the potential impact and control are still uncertain up to date. Based on these background, we design a retrospective study, Risk Factors Promoting Coronary Plaque Progression In China (The RIPPER Study), to solve these issues.
