Filter by: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.
The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.
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 goal of the 3D-CARDIOPATH study is to investigate the potential added value of emerging 3D imaging modalities by imaging ex vivo cardiac specimens (diseased coronary arteries, calcific aortic valves, and thrombotic materials) in 3D. Specifically, 20 cadaveric coronary artery segments with advanced atherosclerosis will be received from 10 patients with SCD. These segments will first be scanned with intravascular imaging modalities, namely optical coherence tomography (OCT) and intravascular ultrasound (IVUS), and then with micro-computed tomography (micro-CT) and light sheet fluorescence microscopy (LSFM). Additionally, 30 thrombotic specimens aspirated from patients with ST-elevated myocardial infarction, will also be scanned using micro-CT. Finally, 30 surgically removed aortic valves will undergo scanning with micro-CT and LSFM. Traditional histopathological assessment will also be performed on the scanned specimens. Patient laboratory profiles, past medical histories, demographic characteristics, and therapeutic management will be recorded, where applicable.
Factorial 2x2, all-comer, multicentre, single-blinded, randomized controlled trial (ratio 1:1:1:1). First, the study will compare (first randomization) the non-inferiority in target lesion failure of angiolite stent versus Xience stent family. Immediately after the first randomization, the study compares (second randomization) the superiority in bleeding Bleeding Academic Research Consortium (BARC) 2, 3, or 5 of abbreviated DAPT versus standard of care. Both primary endpoints will be evaluated at 12 months of follow-up. The study will be patient-observer blinded (participant and investigator doing follow-ups) for the stent type and open-label for the antiplatelet regimen.
Prospective interventional study evaluating clinical and procedural outcomes of patients with ostial left anterior descending artery lesion PCI alone or crossover with left main artery
Patients with Chronic kidney disease are most vulnerable to contrast induced nephropathy after Percutaneous coronary intervention, intravascular ultrasound guidance can be used to safely guide the procedure to reduce the contrast usage, this randomized trial is design to test the hypothesis that IVUS based ultra-low contrast PCI is feasible and can reduce the contrast induced nephropathy.
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.
This study is a multicenter, prospective, blinded (blinding of clinical evaluators), randomized controlled, event-driven non-inferiority clinical trial. Eligible subjects who meet the inclusion criteria will be registered in the central randomization system and randomized in a 1:1 ratio to either the experimental group (CT-FFR guided group) or the control group (QFR guided group).
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.
