Atherosclerosis News and Research RSS Feed - Atherosclerosis News and Research

Atherosclerosis is the progressive buildup of plaque - the fatty deposits and other cells - in the inner walls of the arteries. The condition is a consequence of elevated cholesterol and for many it's a silent disease, with no visible signs or symptoms. The disease can begin in early adulthood and continues to progress for the rest of a person's life. Despite the serious nature of atherosclerosis, many people do not understand how it develops and progresses.
OCT offers safe and better guidance for patients undergoing PCI to treat coronary artery disease

OCT offers safe and better guidance for patients undergoing PCI to treat coronary artery disease

Optical coherence tomography (OCT) provides safe and improved guidance for patients undergoing percutaneous coronary intervention to treat coronary artery disease, according to results from the ILLUMIEN III: OPTIMIZE PCI trial. [More]

Senescent cells drive plaque formation in animal models of atherosclerosis, research shows

Atherosclerosis is a disease in which arteries narrow due to plaques. That narrowing can lead to heart attacks and strokes -- both of which are leading causes of death in the U.S. [More]

High blood pressure in middle age could be potential risk factor for Alzheimer's disease

High blood pressure in middle age can lead to impaired cognition and is a potential risk factor for Alzheimer's disease, according to a statement from the American Heart Association co-authored by Loyola Medicine neurologist José Biller, MD. [More]

Texas Biomed researcher seeks to identify molecular mechanisms underlying early atherosclerosis

Texas Biomedical Research Institute Staff Scientist Dr. Genesio Karere was recently awarded a $609,568 grant from the National Institutes of Health to study and identify molecular mechanisms underlying early atherosclerosis. [More]
Scientists suggest potential approach of lowering tau levels to thwart Alzheimer's disease

Scientists suggest potential approach of lowering tau levels to thwart Alzheimer's disease

Taking a pill that prevents the accumulation of toxic molecules in the brain might someday help prevent or delay Alzheimer's disease, according to scientists at Baylor College of Medicine, Texas Children's Hospital and Johns Hopkins University School of Medicine. [More]
Optical and PET/CT activity-based probes could help in non-invasive imaging of atherosclerotic plaques

Optical and PET/CT activity-based probes could help in non-invasive imaging of atherosclerotic plaques

Researchers at Stanford University have demonstrated for the first time the use of a dual optical and PET/CT activity-based probe to detect atherosclerotic plaques. The study is published in the October issue of the Journal of Nuclear Medicine. [More]
Scientists develop smart drug that safely removes fat from liver and blood vessels

Scientists develop smart drug that safely removes fat from liver and blood vessels

Scientists from the Technical University of Munich and Helmholtz Zentrum München have developed a ‘smart’ drug that safely clears the liver of fat and prevents blood vessels from clogging up. [More]
Calcium supplements may raise risk of plaque buildup in arteries and heart damage

Calcium supplements may raise risk of plaque buildup in arteries and heart damage

After analyzing 10 years of medical tests on more than 2,700 people in a federally funded heart disease study, researchers at Johns Hopkins Medicine and elsewhere conclude that taking calcium in the form of supplements may raise the risk of plaque buildup in arteries and heart damage, although a diet high in calcium-rich foods appears be protective.

Smoking linked to thicker heart walls and worse heart function

Smoking linked to thicker heart walls and worse heart function

Smoking is associated with thicker heart walls and reduction in the heart's pumping ability, two factors associated with increased risk of heart failure, according to new research in the American Heart Association's journal Circulation: Cardiovascular Imaging. [More]
Scientists identify molecule in liver cells that regulates release of fats into the bloodstream

Scientists identify molecule in liver cells that regulates release of fats into the bloodstream

ETH researchers have discovered a molecule in liver cells that controls the release of fat into the bloodstream. This "lock keeper" is present in large quantities in overweight people and leads indirectly to vascular narrowing. [More]
NTU scientists develop new test kit for rapid detection of inflammation in diabetic patients

NTU scientists develop new test kit for rapid detection of inflammation in diabetic patients

Scientists from Nanyang Technological University, Singapore have developed a new kit that will allow doctors to find out within minutes if diabetic patients are suffering from inflammation. [More]
Researchers discover gene variants linked to thoracic aortic dissections

Researchers discover gene variants linked to thoracic aortic dissections

On Super Bowl Sunday, Tina Wilkins was relaxing in her recliner while she chatted on the phone with her mother and waited for the game to begin. She had recently lost 63 pounds and was in better shape than she had been in years. [More]
Stem cells may be responsible for vascular calcification in patients with kidney disease

Stem cells may be responsible for vascular calcification in patients with kidney disease

Scientists have implicated a type of stem cell in the calcification of blood vessels that is common in patients with chronic kidney disease. [More]
Low levels of diastolic blood pressure linked to heart damage risk

Low levels of diastolic blood pressure linked to heart damage risk

By analyzing medical records gathered over three decades on more than 11,000 Americans participating in a federally funded study, researchers at Johns Hopkins Medicine say they have more evidence that driving diastolic blood pressure too low is associated with damage to heart tissue. [More]
UTHealth scientists discover powerful predictors of congestive heart failure

UTHealth scientists discover powerful predictors of congestive heart failure

A team of scientists at The University of Texas Health Science Center at Houston and Baylor College of Medicine, led by Eric Boerwinkle, Ph.D., Richard Gibbs, Ph.D., and Bing Yu, Ph.D., have identified powerful predictors of congestive heart failure, a major cause of hospitalization and death in the United States.

Drug-eluting stents more beneficial to patients undergoing saphenous vein graft angioplasty

Drug-eluting stents more beneficial to patients undergoing saphenous vein graft angioplasty

Drug-eluting stents had a clear advantage over bare metal stents in patients undergoing revascularisation of saphenous (leg) vein grafts, results of the BASKET-SAVAGE trial show. [More]
Lipoprotein apheresis may have new role in patients with refractory angina

Lipoprotein apheresis may have new role in patients with refractory angina

Initial investigation of patients with suspected coronary heart disease (CHD) using functional imaging - rather than guideline-directed care - resulted in significantly less unnecessary angiography, according to results of the CE-MARC 2 trial. [More]
Active strategy of detecting and treating asymptomatic MSAD results in no clinical benefit

Active strategy of detecting and treating asymptomatic MSAD results in no clinical benefit

In patients with high-risk coronary artery disease (CAD), an active strategy of detecting and treating asymptomatic multisite artery disease (MSAD) combined with intensive medical therapy did not improve 2-year outcomes compared to a more traditional approach of managing only symptomatic coronary and extracoronary lesions, new research shows.

Engineered gut bacteria may one day help reduce negative health effects of obesity

Engineered gut bacteria may one day help reduce negative health effects of obesity

A new therapy that involves engineered gut bacteria may one day help reduce the health problems that come with obesity. Incorporating the engineered bacteria into the guts of mice both kept them from gaining weight and protected them against some of the negative health effects of obesity. [More]
