Atherosclerosis News and Research

RSS

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.

Research shows why certain atherosclerotic lesions can turn deadly

A common misconception about arterial plaque is that it inevitably leads to a heart attack or a stroke. New research at Columbia University Medical Center, however, sheds light on why so few plaques in any given individual actually cause a problem. Furthermore, the research has identified a key protein that may promote the conversion from benign to dangerous plaques.

Drugs designed to tackle endoplasmic reticulum stress might be useful in treating heart disease

Researchers say they have evidence to explain what separates your average blood vessel plaque from those that are at high risk for triggering the development of dangerous - even fatal - blood clots.

Urine proteome pattern may predict coronary artery disease

Proteome analysis, a screening requiring only a patient's urine specimen, shows promise as a reliable and noninvasive way to diagnose atherosclerosis and coronary artery disease in the future, according to research presented at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology Annual Conference 2009.

Oral delivery system for RNAi therapeutics

Researchers at the University of Massachusetts Medical School (UMMS) report on a novel approach to the delivery of small bits of genetic material in order to silence genes using "RNA interference"-and in the process, discovered a potent method of suppressing inflammation in mice similar to what occurs in a range of human diseases.

Researchers identify atrial fibrillation as a stroke predictor in black patients

Predictors of atrial fibrillation (AF or afib) might offer physicians a better way to prevent stroke in blacks, according to a new study done by researchers at Wake Forest University School of Medicine.

New findings on COX-2 inhibitor side effects

In searching for a simple way to identify individuals with smoking-related lung injury, scientists at Weill Cornell Medical College have stumbled upon a potential explanation for why the class of pain-relievers known as COX-2 inhibitors increases the risk of heart problems among users.

Discovery of gene variation linked to increased risk of ischemic stroke

Millions of people have a genetic variant linked to increased risk of ischemic stroke, reports an international research team including scientists at The University of Texas Health Science Center at Houston in a study published online by The New England Journal of Medicine on April 15.

Merck & Co and Cardiome sign agreement for Vernakalant

Merck & Co., Inc. and Cardiome Pharma Corp. has announced a collaboration and license agreement for the development and commercialization of vernakalant, an investigational candidate for the treatment of atrial fibrillation.

Inflammatory chemokine may explain diseases that come with obesity

An inflammatory factor already linked to several diseases, including pulmonary disease, lung cancer, and arthritis, may also be responsible for the insulin resistance that comes with obesity, according to a new study published in the April issue of Cell Metabolism.

New family of biologically active products of omega-3 fatty acids show potential to resolve periodontal inflammation

Periodontal (gum) disease is a chronic inflammation initiated by bacteria that affect the gums and bone supporting the teeth, and may eventually result in tissue and tooth loss.

Accurate assessment of heart disease leads to earlier, more aggressive therapy

In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.

In lab supplements of lipoic acid lower triglyceride levels

Studies done with laboratory rats suggest that supplementation of their diet with lipoic acid had a significant effect in lowering triglycerides, which along with cholesterol levels and blood pressure are one of the key risk factors in cardiovascular disease.

CRESTOR found to reduced CV risk in patients achieving low LDL-C and hsCRP targets in new Jupiter analysis

Results from a new sub-analysis of the JUPITER study show that patients who attained a dual treatment target of LDL-C <70mg/dL and high-sensitivity C-reactive protein (hsCRP) <2mg/L with CRESTOR (rosuvastatin) 20mg achieved a greater reduction in cardiovascular events compared to placebo than those who did not (65% vs 36%, p=0.033) among men and women with low to normal cholesterol levels and elevated hsCRP.

CRESTOR (rosuvastatin) shown to significantly reduce risk of venous thromboembolism

A new analysis from the JUPITER study shows that CRESTOR (rosuvastatin) 20mg significantly cut the risk of venous thromboembolism (VTE) by 43% (p=0.007) compared to placebo among men and women with low to normal cholesterol levels and elevated high-sensitivity C-reactive protein (hsCRP).

Researcher links cholesterol crystals to cardiovascular attacks

For the first time ever, a Michigan State University researcher has shown cholesterol crystals can disrupt plaque in a patient's cardiovascular system, causing a heart attack or stroke.

Simple, noninvasive finger sensor test predicts major cardiac events

Results of a Mayo Clinic study show that a simple, noninvasive finger sensor test is "highly predictive" of a major cardiac event, such as a heart attack or stroke, for people who are considered at low or moderate risk, according to researchers.

Levels of PLTP enzyme in blood should be a consideration for potential statin treatment

In a patient study of over 1,000 individuals with coronary artery disease (CAD), researchers have found that high levels of an enzyme called PLTP significantly increased the risk of heart attack in the subset of patients taking statins.

Injected luminol glows blue revealing immune cells' misdeeds

Detectives on television shows often spray crime scenes with a compound called luminol to make blood glow.

Drug pactimibe does not appear to reduce progression of atherosclerosis

Compared to placebo, the drug pactimibe did not effect certain measures of atherosclerosis for patients with familial hypercholesterolemia (high cholesterol levels), but these patients did have an increased incidence of cardiovascular events such as heart attack and stroke, according to a study in the March 18 issue of JAMA.
