Active clinical trials for "Arteriosclerosis"

Coronary artery disease are 8 times more prevalent in patients with NAFLD then the general population and are being considered the most common cause of death. Cardiac CT is a reliable non invasive method in demonstrating Coronary Plaques. However the association between coronary artery calcium score (CAC) and NAFLD remains controversial

The goal of this study is to evaluate the possible preoperative predictive value of altered heart rate variability (HRV) and baroreflex sensitivity in different sleep stages for postoperative adverse cardiac events (i.e. arrhythmia or myocardial ischemia needing hospitalization or medication, myocardial ischemia assessed by enzyme release, myocardial infarction, sudden cardiac death, stroke) in arteriosclerosis obliterans patients.

The purpose of this study is to test if a patient can be directly connected to a quality assurance (QA) database, traditionally known as a registry. Patient-reported outcomes (PRO) data will be entered into the database directly from a patient's mobile phone from their index procedure for 12 months. The investigators hope this study to be a "proof of concept" for such a distributed registry and evaluate 1) consistency of data acquisition, 2) engagement of patients, 3) overall value of patient-reported outcomes to enhance long term follow up.

Compared with standardized western medical drug therapy, this study is mainly about whether the combination of standardized western medical drug therapy and Chinese medical continued treatment, can further decrease the rate of cardiovascular events for stable angina patients and change the condition of angina.

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. The purpose of the FAVOR II China study is to evaluate the diagnostic accuracy of on-line QFR with FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies between online QFR and online QCA, with FFR as the reference standard.

This study examines the relationship between the SCOUT DM device and coronary artery calcification as determined by rapid computed tomography in patients at risk for coronary heart disease.

The first aim of this study is to determine how often unrecognized myocardial infarction occur in patients using a magnetic resonance imaging (MRI) technique (known as delayed enhancement MRI), as compared to the electrocardiogram. The second aim of this study is to determine the severity of coronary heart disease of the patients with unrecognized myocardial infarction. The final aim is to determine how the presence of unrecognized myocardial infarction detected by the MRI affects lifespan.

To investigate the relationship of vascular cell phenotypes to atherosclerosis.

To evaluate the relation of retinal microvascular characteristics to subclinical cardiovascular disease, clinical disease, and their risk factors in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.

This trial is designed to associate angiography-based fractional flow reserve (3D-angio-based FFR) values with optical coherence tomography findings in pre- and post-percutaneous coronary intervention in patients with non-ST segment elevation acute coronary syndromes.
