Active clinical trials for "Atherosclerosis"

A long-term evaluation of the impact of intensive diet and lifestyle intervention on coronary plaque dynamics in patients with coronary atherosclerosis diagnosed in computed tomography angiography (CCTA). 92 patients who completed the Dietary Intervention to Stop COronary Atherosclerosis in Computed Tomography study (DISCO-CT, NCT02571803) will be followed-up.

A computerized registry of cardiovascular disease patients in a large health maintenance organization in Israel. The registry is aimed to be used by health professionals to identify cardiovascular disease patients and to follow the courses of their illnesses and risk factors.

The goal of this study is to assess a slimy substance that settles/deposits along blood vessel wall. This slimy substance is called plaque. Plaque could be made up of fat, calcium or both. Plaque deposition narrows the vessels. This leads to decreased blood flow to various parts of body. Blood vessels include vessels that supply to heart (coronary), vessels to brain (carotid), vessels to kidneys (renal) and vessels to legs (femoral). Decreased blood flow causes symptoms such as brain stroke, heart attack, leg pain. Similarly individuals at risk of cardiovascular disease can have certain markers elevated in their blood that can be measured by simple blood tests. High or increased plaque deposition is seen in neck vessels of cancer patients who received radiation to chest or head and neck as part of their cancer treatment. Cancer survivors are at increased risk of plaque development and are therefore called high-risk population. Exercise +/- fat lowering medicine can potentially decrease plaque deposition and statins are one of the several fat lowering medications.

The goal of this observational study is to determine the diagnostic accuracy of peripheral whole blood transcriptomes analyzed by an artificial intelligence algorithm to detect the presence and extent of coronary calcification in individuals without a history of known cardiovascular disease. The main question it aims to answer is: 1. Will the proposed method predict the presence and extent of coronary artery calcification from the peripheral whole-blood transcriptomes?

This is a randomized QI project evaluating the impact of notifying both patients and their clinicians of presence of incidental coronary artery calcium (CAC) on initiation or intensification of lipid-lowering therapy in patients with ASCVD who are not receiving guideline-directed lipid-lowering therapy or have LDL cholesterol (LDL-C) ≥70 mg/dL.

The CANARY (Coronary Assessment by Near-infrared of Atherosclerotic Rupture-prone Yellow) Study is a pivotal trial to evaluate criteria for defining a Lipid Core Plaque (LCP) that is at high risk of rupturing during standard of care therapy and causing intra-procedural complications. If plaques that require treatment are at higher than normal risk of causing intra-procedural complications, some life threatening, the treating physician is better informed and may opt to take precautionary measures to mitigate the risk or result of a complication. The CANARY Study is also designed to evaluate the feasibility of using a distal embolization protection device (EPD) as a means to prevent heart attacks triggered by the embolization of plaque during standard care therapy. It is thought that the EPD will prevent plaque from going downstream during treatment and obstructing other heart vessels. These obstructions could cause heart attacks by preventing blood from reaching heart muscle tissue.

This is a prospective study of the environmental and genetic factors that influence the development of cardiovascular disease (CVD) in African American men and women. The cohort is a collaboration among multiple institutions (Jackson State University, Mississippi State Department of Health, Tougaloo College, and the University of Mississippi Medical Center), the National Institute on Minority Health and Health Disparities (NIMHD), and the National Heart, Lung, and Blood Institute (NHLBI).

The investigators will conduct a study of brain positron emission tomography (PET) using 11C-PIB for the imaging of brain amyloid in 250 participants in the Multiethnic study of atherosclerosis (MESA) at Columbia University Irving Medical Center in New York City. Participants will be imaged only once with Pittsburgh Compound B (PIB) PET.

The purpose of the SMART-EXAM (SMart Angioplasty Research Team-Pragmatic Randomized Trial for Comparing Routine versus As-Needed EXercise or Pharmacologic Stress Testing in Asymptomatic Patients with High-Risk Coronary CalciuM) trial is to compare the major adverse cardiovascular events between routine stress testing and as-needed stress testing in asymptomatic patients with high-risk coronary calcium (Agatston Score ≥ 400) without proven ASCVD.

The goal of this non-randomized controlled trial is to assess the impact of disclosing a high polygenic risk result for coronary artery disease and subsequent screening to detect subclinical coronary atherosclerosis on change in cardiovascular health over one year.
