Using archival documents, a new report examines the sugar industry’s role in coronary heart disease research and suggests the industry sponsored research to influence the scientific debate to cast doubt on the hazards of sugar and to promote dietary fat as the culprit in heart disease.

Protect kids from toxic secondhand smoke, experts urge

second hand smoke

second hand smoke

It’s advice most smokers with children probably take lightly, but they shouldn’t. Parents and policy advocates should take a “zero tolerance” approach to exposing children to secondhand cigarette smoke, which can be responsible for lifelong cardiovascular consequences in addition to respiratory and other health issues.

The new findings heart repair research

broken heart

Scientists trying to find ways to regenerate a damaged heart have shed more light on the molecular mechanisms that could one day make this a reality.  Whilst other organs such as the liver can regenerate, the heart muscle has very little ability to do so after suffering damage, such as a heart attack.
In the womb the body is able to produce heart muscle cells but soon after birth it effectively stops producing them.

The high levels of caffeine in energy drinks may lead to cardiac complications. A new case report adds to previous reports of adverse cardiovascular events related to consuming energy drinks, including abnormal heart rhythms (arrhythmias).

So if you are one of the bodybuilders, powerlifters, marathon runners, or just people who like to binge-eat every now and then — no judgment all you can eat pizza day is a thing I’m told telling myself — there is some bad news. If you like to preload carbs like they are the magic bullet to your workout woes, you may want to rethink it because according to a new study, it can have an acute and detrimental effect on heart function.

A new cholesterol-lowering vaccine leads to reductions in ‘bad’ LDL cholesterol in mice and macaques, according to research. The authors of the study, from the University of New Mexico and the National Institutes of health in the United States, say the vaccine has the potential to be a more powerful treatment than statins alone.

One energy drink may increase heart disease risk in young adults

One energy drink may increase heart disease risk in young adults

New research shows that drinking one 16-ounce energy drink can increase blood pressure and stress hormone responses significantly. This raises the concern that these response changes could increase the risk of cardiovascular events.

Can exercise be replaced with a pill?

Can exercise be replaced with a pill?

Everyone knows that exercise improves health, and ongoing research continues to uncover increasingly detailed information on its benefits for metabolism, circulation, and improved functioning of organs such as the heart, brain, and liver. With this knowledge in hand, scientists may be better equipped to develop “exercise pills” that could mimic at least some of the beneficial effects of physical exercise on the body. But a review of current development efforts ponders whether such pills will achieve their potential therapeutic impact, at least in the near future.

Study of 83,000 veterans finds cardiovascular benefits to testosterone replacement

Study of 83,000 veterans finds cardiovascular benefits to testosterone replacement

A Veterans Affairs database study of more than 83,000 patients found that men whose low testosterone was restored to normal through gels, patches, or injections had a lower risk of heart attack, stroke, or death from any cause, versus similar men who were not treated. The study also found that men who were treated but did not attain normal levels did not see the same benefits as those whose levels did reach normal.

Mohamed Boutjdir, PhD, professor of medicine, cell biology, and physiology and pharmacology at SUNY Downstate Medical Center, has led a study with international collaborators identifying the mechanism by which patients with various autoimmune and connective tissue disorders may be at risk for life-threatening cardiac events if they take certain anti-histamine or anti-depressant medications. Dr. Boutjdir is also director of the Cardiac Research Program at VA New York Harbor Healthcare System.

Power of the media’s impact on medicine use revealed

Television doctors

More than 60,000 Australians are estimated to have reduced or discontinued their use of prescribed cholesterol-lowering statin medications following the airing of a two-part series critical of statins by ABC TV’s science program, Catalyst, a University of Sydney study reveals. The analysis of the Pharmaceutical Benefits Scheme medication records of 191,000 people revealed that there was an immediate impact after Catalyst was aired in October 2013, with 14,000 fewer people dispensed statins per week than expected.

Milk proteins may protect against cardiovascular disease

milk advertisement The Maillard reaction is a chemical reaction between amino acids and reducing sugars that results in browned foods like seared steaks and toasted bread. When proteins and sugars are mixed together and heated, new chemical compounds are formed. Some are responsible for new flavors and some, according to a new study, may protect us against cardiovascular disease. (more…)


Artificial blood vessel lets researchers assess clot removal devices

endovascular clot removal

For the first time, researchers have created an in vitro, live-cell artificial vessel that can be used to study both the application and effects of devices used to extract life-threatening blood clots in the brain. The artificial vessel could have significant implications for future development of endovascular technologies, including reducing the need for animal models to test new devices or approaches.

New therapy halts artery plaque growth and suppresses inflammation

heart disease

According to the CDC, 1 in 4 deaths are due to heart attacks. In fact it is the leading cause of death for both men and women. Largely attributed to diet, most medications solely aim at lowering cholesterol. However, a research team showed that a nanotherapeutic medicine can halt the growth of artery plaque cells resulting in the fast reduction of the inflammation that may cause a heart attack, offering a new way to treat people at risk for heart disease.
