Filter by:The purpose of this study is (1) to determine whether 24-month dual antiplatelet therapy (DAPT) is superior to 12-month DAPT after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) with respect to major adverse cardiovascular and cerebrovascular events (all-cause death, myocardial infarction, or stroke) in patients with elevated lipoprotein(a)[Lp(a)] levels (>30mg/dL); (2) to determine whether 24-month DAPT is non-inferior to 12-month DAPT after PCI with DES with respect to net adverse clinical events (all-cause death, myocardial infarction, stroke or Bleeding Academic Research Consortium [BARC] type 3 or 5 bleeding) in patients with elevated Lp(a) levels (>30mg/dL).
This study evaluates the short-term and long-term patency of the radial artery and the No-touch vein in patients undergoing isolated on-pump/off-pump coronary artery bypass graft (CABG) surgery. A total of at least 774 patients undergoing isolated on-pump/off-pump CABG will be consecutively recruited from Fuwai Hospital and randomly assigned to receive radial artery or No-touch saphenous vein as their second graft. All participants will be invited for clinical follow-up and 64-slice multislice computed tomography angiography (MSCTA) analysis at 3 months and 12 months post-operatively.
The goal of this clinical trial is to compare two guiding catheters in patients with coronary artery disease during a percutaneous coronary intervention between Guidex® Guiding catheter (DEMAX) and Launcher™ coronary guide catheters (Medtronic). The main question[s] it aims to answer are: - Aren't the safety of medical devices inferior to each other? - Aren't the efficacyof medical devices inferior to each other? Participants will be randomized (1:1) and have a percutaneous coronary interventionwith one of the two guiding catheters.
The present case-control study is designed to investigate the disease characteristics of IR-CAD by comparing the demographics, clinical features, lab results, imaging findings, and prior treatment between 20 patients with IR-CAD and 10 patients with AS-CAD.
This is a prospective pilot study to evaluate the safety, tolerability and efficacy of utilizing precise computer controlled gas challenge in healthy subjects for identification of coronary artery disease.
The purpose of this study is to compare the effect of ticagrelor versus placebo in patients with chronic coronary disease undergoing coronary artery bypass grafting.
The investigators will implement a patient-centered outcomes tool for participants in lung cancer screening programs that receive clinically important incidental findings relevant to heart, breast and lung health. The study objective is to evaluate participant response and clinical follow-up following implementation of a patient-centered incidental findings communication tool.
The goal of this observational study is to learn about a new type of computed tomography (Photon-Counting Detector CT) in patients with coronary artery disease. The main questions it aims to answer are: - How good is the image quality for the new CT - How accurate are measurements in the images of the new CT - Is there a relationship between measurements in the images and the management of the disease (e.g. new medication or additional investigations) - Is there a relationship between measurements in the images and the results of follow-up investigations - Is there a relationship between measurements in the images and the patient outcome Participants will undergo normal clinical assessment of coronary artery disease and all data from the CT scan and additional investigations will be collected. There will be no additional investigations for the purpose of the study. After 1, 2 and 5 years, participants will be asked to answer a health questionaire.
The purpose of this study is to elucidate the imaging mechanisms of cognitive function changes in patients with coronary heart disease before and after surgery or conservative treatment, and to evaluate and predict the postoperative neurological function recovery and cerebrovascular health level of patients by combining serum markers and patient cardiovascular health evaluation indicators.
To verify the effectiveness and safety of minimally invasive coronary artery bypass grafting for complete revascularization of multivessel coronary artery disease via inferior part-sternotomy, We aim to randomize 260 patients undergoing isolated Coronary artery bypass grafting (CABG) to compare the ratios of complete revascularization between inferior part-sternotomy CABG and full median sternotomy CABG from 9 hospitals in China.
