Equipping more state police cruisers with AEDs can save lives

Just 30 percent the nation's state police agencies reported that they equip their vehicles with automated external defibrillators, and of those, nearly 60 percent of said only a minority of their fleet have the lifesaving devices on board, according to new research from the Perelman School of Medicine at the University of Pennsylvania that will be presented today at the American Heart Association's annual Scientific Sessions.

Low SBP levels within normal range may reduce risk of recurrent stroke

Among patients who experienced an ischemic stroke, systolic blood pressure levels of less than 120 mm Hg, or higher than 140 mm Hg, were associated with an increased risk of subsequent stroke, according to a study appearing in the November 16 issue of JAMA, a theme issue on cardiovascular disease. This issue is being released early online to coincide with the American Heart Association Scientific Sessions.

New CAD test associated with higher rates of cardiac procedures, health-care spending

A new, noninvasive diagnostic test for coronary artery disease is associated with a higher rate of subsequent invasive cardiac procedures and higher health-care spending. That's according to an observational study of Medicare recipients conducted by researchers at the Stanford University School of Medicine.

Grants up to $30 million for those with innovative ideas for healthcare

The Obama administration on Monday announced a $1 billion federal fund allocation for last year's health reform law to be channeled toward innovation programs designed to boost jobs and improve patient care.

Cholesterol drugs clash head on

Major cholesterol lowering drugs are being pitched against each other. The cheaper ones are more likely to win say experts.

Geron bows out of stem cell research

Geron Corp. is removing itself from the field it pioneered – stem cell research. Late Monday, the company said it would halt its study of a stem cell-based treatment for spinal cord injury, the first embryonic stem cell trial approved in the U.S.

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.
