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.

Higher levels of exposure to traffic-related air pollution linked to changes in right ventricle of the heart

Exposure to high levels of traffic-related air pollution is associated with changes in the right ventricle of the heart that may contribute to the known connection between air pollution exposure and heart disease, according to a new study. [More]
Research shows depletion of cholesteryl ester impairs prostate cancer aggressiveness

Research shows depletion of cholesteryl ester impairs prostate cancer aggressiveness

Researchers have discovered a link between prostate cancer aggressiveness and the accumulation of a compound produced when cholesterol is metabolized in cells, findings that could bring new diagnostic and treatment methods. [More]
Noninvasive imaging with MRI of carotid artery plaque accurately predicts future cardiovascular events

Noninvasive imaging with MRI of carotid artery plaque accurately predicts future cardiovascular events

Noninvasive imaging of carotid artery plaque with MRI can accurately predict future cardiovascular events like strokes and heart attacks in people without a history of cardiovascular disease, according to a new study published online in the journal Radiology. [More]

Blocking Netrin-1 in immune system stops chronic inflammation and insulin resistance tied to obesity

Researchers at NYU Langone Medical Center have found that blocking the action of a key signaling molecule in the immune system known as Netrin-1 stalls chronic inflammation and insulin resistance tied to obesity and often derived from fatty diets. [More]

Study finds significant reduction in hospital admissions with Medicare Part D prescription coverage

A new study by the Johns Hopkins Bloomberg School of Public Health and the University of Illinois at Chicago finds that Medicare Part D prescription coverage significantly reduced hospital admissions and program expenditures totaling $1.5 billion annually. [More]
Researchers analyze impact of chocolate consumption in vascular health

Researchers analyze impact of chocolate consumption in vascular health

It might seem too good to be true, but dark chocolate is good for you and scientists now know why. Dark chocolate helps restore flexibility to arteries while also preventing white blood cells from sticking to the walls of blood vessels. [More]

Scientific Statement details latest evidence for diagnosis and treatment of fibromuscular dysplasia

A vascular disease called fibromuscular dysplasia, which can cause high blood pressure, kidney failure, stroke and other symptoms -- mostly in women -- is "poorly understood by many healthcare providers," according to a Scientific Statement from the American Heart Association. [More]
New scientific blood analysis predicts short-term mortality in humans

New scientific blood analysis predicts short-term mortality in humans

The general state of a person's metabolism can be diversely illustrated with a new scientific blood analysis. With the aid of the analysis biomarkers predicting short-term mortality have now been discovered [More]

Research roundup: Palliative care and ACOs; employers and Supreme Court case on contraception

In preparation for the new ACO environment, leaders recognized the contribution palliative care can make to health care "value," especially in the care of our sickest (and most expensive) patients ... [More]

Medicaid patients have longer lengths of stay for treatment of heart failure, shows study

Heart failure accounts for 6.5 million hospital days a year, and a new study reported in the Journal for Healthcare Quality showed that Medicaid patients and those with comorbid illnesses have longer lengths of stay for treatment of heart failure. [More]

New 256-slice CT scanner to predict potential heart attack in one second

What can you do in one second? Snap your fingers, blink your eyes, or get a diagnostic scan on a 256-slice computed tomography (CT) scanner? You can do all of those things in one second, but the one that may help save your life is the 256-slice CT scan. [More]
Exposure to common infections linked to memory and brain function

Exposure to common infections linked to memory and brain function

Exposure to common infections is linked to memory and brain function - even if the infections never made you ill, according to research presented at the American Stroke Association's International Stroke Conference 2014. [More]

Study: Whole diet approach has more evidence for reducing CV risk than reduced dietary fat

A study published in The American Journal of Medicine reveals that a whole diet approach, which focuses on increased intake of fruits, vegetables, nuts, and fish, has more evidence for reducing cardiovascular risk than strategies that focus exclusively on reduced dietary fat. [More]
Researchers develop multifunctional nanoparticle to pinpoint blood vessel plaques

Researchers develop multifunctional nanoparticle to pinpoint blood vessel plaques

A team of researchers, led by scientists at Case Western Reserve University, has developed a multifunctional nanoparticle that enables magnetic resonance imaging (MRI) to pinpoint blood vessel plaques caused by atherosclerosis. [More]

Whole diet approach has more evidence for reducing cardiovascular risk

A study published in The American Journal of Medicine reveals that a whole diet approach, which focuses on increased intake of fruits, vegetables, nuts, and fish, has more evidence for reducing cardiovascular risk than strategies that focus exclusively on reduced dietary fat. [More]
Scientists engineered microchip coated with blood vessel cells to study cardiovascular nanomedicine

Scientists engineered microchip coated with blood vessel cells to study cardiovascular nanomedicine

Designing nanomedicine to combat diseases is a hot area of scientific research, primarily for treating cancer, but very little is known in the context of atherosclerotic disease. [More]
Five important numbers to keep cardiovascular system healthy

Five important numbers to keep cardiovascular system healthy

Pass codes, phone numbers, social security numbers, clothing sizes and addresses. We all have a lot of numbers in our heads, but heart experts at The Ohio State University Wexner Medical Center say there are five more you need to know to help keep your cardiovascular system healthy. [More]

Biomarker used to diagnose brain injury shows early promise for assessing heart inflammation

A biomarker widely used to diagnose brain injury has shown early promise for assessing the severity of heart inflammation, or myocarditis, find researchers at Columbia University's Mailman School of Public Health, Johns Hopkins, and the Mayo Clinic. [More]

Cleveland Clinic: Process that turns HDL cholesterol bad discovered

Cleveland Clinic researchers have discovered the process by which high-density lipoprotein (HDL) - the so-called "good cholesterol" - becomes dysfunctional, loses its cardio-protective properties, and instead promotes inflammation and atherosclerosis, or the clogging and hardening of the arteries.
