Coronary calcium scoring can determine risk of cardiac events

If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you're not likely to have a heart attack in the next seven to 10 years?

Insulin sensitivity in the ovaries and the pituitary linked to infertility

Infertility is common among obese women, but the reasons remain poorly understood and few treatments exist. Now a team of Johns Hopkins Children's Center scientists, conducting experiments in mice, has uncovered what they consider surprising evidence that insulin resistance, long considered a prime suspect, has little to do with infertility in women with type-2 diabetes, polycystic ovary syndrome and metabolic syndrome, all obesity-related conditions.

Atherosclerotic plaques spread downstream in coronary arteries

In human coronary arteries, atherosclerotic plaques tend to spread downstream because of the changes in blood flow patterns the plaque causes, researchers have found.

CDCs can increase healthy heart muscle cells in patients with ischemic heart disease

Healthy, new heart cells have been generated by animals with chronic ischemic heart disease after receiving stem cells derived from cardiac biopsies or "cardiospheres," according to research conducted at the University at Buffalo School of Medicine and Biomedical Sciences.

Frequent counseling, physician support and interactive website help obese patients lose weight

Obese patients enrolled in a weight-loss program delivered over the phone by health coaches and with website and physician support lost weight and kept it off for two years, according to new Johns Hopkins research. The program was just as effective as another weight-loss program that involved in-person coaching sessions.

Conventional approach could soon increase recurrent stroke risk after first event

For patients who have suffered an ischemic stroke, traditional treatment prescribes keeping subsequent blood pressure levels as low as possible to reduce the risk of another stroke. A new international study, however, suggests this conventional approach may not be helpful, and could actually increase recurrent stroke risk - at least in the first few months after the first event.

AHA honors Gladstone senior investigator with Distinguished Scientist Award

The American Heart Association will today present Gladstone Institutes Senior Investigator and President Emeritus Robert Mahley, MD, PhD, with the 2011 AHA Distinguished Scientist Award, bestowing yet another honor on one of Gladstone's founding cardiovascular scientists.

Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

Blood-based gene expression test more effective in ruling out obstructive CAD

A blood-based gene expression test was found to be more effective for ruling out obstructive coronary artery disease in stable symptomatic patients than myocardial perfusion imaging (MPI), a common test that uses a radioactive agent to evaluate the blood flow and function of the heart.

Rosuvastatin as effective as atorvastatin in reversing atherosclerosis

Maximum doses of Crestor- (rosuvastatin) or Lipitor- (atorvastatin) are similarly effective in reversing the buildup of cholesterol plaques in the coronary artery walls (atherosclerosis) after 24 months of treatment, according to Cleveland Clinic researchers.

Study: Pneumonia the most common serious infection post-heart surgery

Pneumonia - not a deep incision surgical site infection - is the most common serious infection after heart surgery, according to new research presented at the American Heart Association's Scientific Sessions 2011.

Niacin not effective in reducing risk of stroke, heart attack in stable CV patients

In patients whose bad cholesterol is very well-controlled by statins for a long time period, the addition of high-dose, extended release niacin did not reduce the risk of cardiovascular events, including heart attack and stroke.

Research offers clues that may explain behavior, mood changes in stress-related disorders

Research released today uses the latest genetic tools to explore how stress alters brain function, leading to anxiety, depression, and other stress-related mood disorders.

Combination of antipsychotic and antidepressant drugs may increase risk of CV mortality

People taking anti-psychotic drugs and anti-depressant drugs have a much higher risk of dying during an acute coronary event of a fatal arrhythmia than the rest of the population, finds a Finnish study published in the European Heart Journal.

International consortium develops first-in-class adiponectin receptor agonist

A compound that mimics the effects of adiponectin, a beneficial protein that is produced by fat tissue in healthy weight individuals and may exhibit protective effects against cancer, cardiovascular disease, inflammatory conditions and insulin resistance has been developed by an international consortium lead by Dr. Eva Surmacz, Associate Professor in Biology (Adjunct) and director of the Obesity and Cancer Program at the Sbarro Institute for Cancer Research and Molecular Medicine at Temple University's College of Science and Technology.

New health institute to combat chronic diseases across Maryland

Jay A. Perman, MD, President of the University of Maryland, and Joshua M. Sharfstein, MD, Secretary of the Maryland Department of Health and Mental Hygiene (DHMH), announced today the creation of the Institute for a Healthiest Maryland, a collaboration of support systems that will guide efforts to combat chronic diseases across Maryland.

Evacetrapib drug may increase HDL-C and decrease LDL-C levels

Among patients with sub-optimal low-density lipoprotein cholesterol (LDL-C) or high-density lipoprotein cholesterol (HDL-C) levels, use of the drug evacetrapib alone or in combination with statin medications was associated with significant increases in HDL-C levels and decreases in LDL-C levels, according to a study appearing in the November 16 issue of JAMA, a theme issue on cardiovascular disease.

Type 2 diabetics with low cholesterol may carry residual risk of cardiac events

LipoScience, Inc., an in-vitro diagnostic company advancing patient care in cardiovascular, metabolic and other diseases using an innovative and proprietary platform based on nuclear magnetic resonance (NMR) technology, recognizes a presentation of clinical data which suggests that type 2 diabetics with low non-HDL and low LDL cholesterol may carry residual risk of a cardiac event based on high LDL particle numbers.

Scientists discover definitive role for brain in regulating loss of muscle mass

Patients with cancer, heart disease and other chronic illness struggle not only with complications inherent to their disease, they also experience an involuntary loss of weight and muscle mass triggered by the body's natural response to infection and inflammation. Increasing nutrition intake does not mitigate the process and there is no treatment.

EPO-secreting engineered vessels could reverse anemia

Patients who rely on recombinant, protein-based drugs must often endure frequent injections, often several times a week, or intravenous therapy. Researchers at Children's Hospital Boston demonstrate the possibility that blood vessels, made from genetically engineered cells, could secrete the drug on demand directly into the bloodstream.
