Active clinical trials for "Plaque, Atherosclerotic"

Background Incidence of perioperative stroke In cardiac surgery is 2.6-5.2%. Ascending aortic atheromatous plaque and stroke are strongly associated. Propose of study To determine incidence of ascending aortic atheroma in Thai people To identify risk factors which associated with ascending aortic atheroma Methodology After received standard general anesthesia and start sternotomy. Epiaortic scan will be performed by surgeon use L15-7i Phillips® ultrasound probe cover with sterile cover. Five standard epiaortic views will be collected. Epiaortic clips will be review and determine about atheroma by two qualified echocardiographers. Atheroma more than third grade will defined to significant. Potential risk factors of atheroma will be gather from medical record To assess the relationship between risk factors and atheroma a univariate analysis was performed using an unpaired t-test and a Chi-square test. For higher accuracy regarding the impact of single risk factors, a multiple logistic regression analysis was also performed.

Biofilm has been identified as the major bacterial phenotype contributing to atherosclerosis. It has become very important to evaluate atherosclerosis and the role of biofilm using advanced technologies. It is also important to understand wound biofilm at a genetic and a molecular level.

This study evaluated optimal macrophage diagnosis algorithm through comparative analysis between coronary artery, OCT image, and IVUS, and improve a diagnosis rate of vulnerable coronary plaque accompanied with macrophage infiltration.

Unstable plaque, the primary cause of myocardial infarction, is characterized by distinct a morphology including positive remodeling (PR), low attenuated plaque (LAP), napkin ring sign (NRS), and spotty calcifications (SC) The purpose of the present study is to investigate the influence of microvascular dysfunction and additional risk factors on plaque morphology and plaque burden in patients with diabetes mellitus.

This proposed follow-up study aims to recruit participants from the original BioImage cohort for a one-time follow-up examination. The repeat ultrasound scan of the carotid arteries will provide information on the natural history of carotid atherosclerosis and factors that contribute to plaque progression. Renewal of the HIPAA authorization will also be sought for 5 years to continue to monitor claims and other information for major cardiovascular events, other outcomes and healthcare utilization.

Assessment of Change in AtheROSclerotic Plaque by Serial CCTA (ACROSS) is designed as a prospective observational study which aim is to demonstrate the effect of statins on coronary atherosclerosis, assessed by quantitative analysis of CCTA.

A Perspective, Self-control Study on the Progression of Carotid Plaques in Anti-PD-1 mAb Treated Tumor Patients by Artery Ultrasound Follow-up

Multi-center Observational Study on the Progression of Atherosclerotic Plaques in Anti-PD-1 mAb Treated Tumor Patients by Artery Ultrasound Follow-up

Stroke is a major cause of death and disability worldwide. Stenotic carotid arteries can lead to stroke if the cause of the stenosis is a vulnerable atherosclerotic plaque. Recent studies reveal that if a patient has a plaque in the carotid artery it is highly probable that he/she will develop plaques in other superficial arteries like the femoral artery. Currently, duplex ultrasound is used to determine the grade of stenosis and is the main criterion for intervention (endarterectomy) planning. However, the stability, or instability of the plaque cannot be determined non-invasively. Photoacoustics is a novel, non-invasive imaging modality that uses pulsed laser light to generate laser induced ultrasound in the absorbing region of the tissue. Photoacoustic imaging provides optical contrast of biological tissue chromophores with an acoustic resolution and imaging depth, which is promising for visualization of plaque composition. The advantage of photoacoustics is the use of multiple wavelengths, since different tissues respond differently to different wavelengths. Hence, non-invasive, in vivo, morphology assessment is a future application of this new modality that would improve diagnosis and clinical decision making. The drawback is the limited penetration depth of the laser light and the signals generated by surrounding tissue. A new, integrated photoacoustic device has been developed that meets all safety requirements and has an improved penetration depth, suitable for imaging of carotid arteries with the aim to distinguish between plaques with different morphology.

Although advances in knowledge of the prevention, diagnosis and treatment of atherothrombosis are encouraging, cardiovascular diseases (CVD), with acute and chronic ischemic heart disease in particular, remain a major cause of disability and premature death throughout the world. Cardiac rehabilitation (CR) and secondary prevention are coordinated multidimensional evidence-based strategies that aim to assist patients with acute and chronic ischemic heart disease return to an active and satisfying life and to prevent the recurrence of further cardiac events. Since CR is time limited after an acute event, secondary prevention proposes a continuum where care is provided for the rest of a person's life according to the existence of cardiovascular risk factors. Secondary prophylaxis is fundamental for the recovery of the patient, but in most cases, it is only insufficiently implemented. To ensure adequate resources for the delivery of health care and to further improve the level of care, care-delivery models need to be changed in a way that patients themselves become more involved in their own care. Mobile health (mHealth) is a rapidly growing health delivery methodology with the potential to impact on health care research, health care delivery and health outcomes. Therefore, the aim of the study is to determine the impact of plaque visualization using a digital intervention on treatment adherence to improve the cardiovascular risk profile. Participants will be randomized into two groups: intervention group and control group. Participants of the control group receive the best medical care according to current guideline recommendations without access to the app. Participants of the intervention group receive the best medical care according to current guideline recommendations with full access to the Smartphone application at time of study begin until the completion of the follow-up period of 12 months. The access to the app includes access to relevant findings including ultrasound images of the carotid artery, lipid profile, blood pressure values, and weight.
