FDA Approves Blood Test That Gauges Heart Attack Risk

The screen is meant for people without history of heart disease, agency says.

  

Patients with Lp-PLA2 activity greater than the level of 225 nanomoles per minute per milliliter are at increased risk for heart attacks.

The U.S. Food and Drug Administration on Monday approved a new blood test that can help determine a person's future odds for heart attack and other heart troubles.
The test is designed for people with no history of heart disease, and it appears to be especially useful for women, and black women in particular, the agency said.
"A cardiac test that helps better predict future coronary heart disease risk in women, and especially black women, may help health care professionals identify these patients before they experience a serious [heart disease] event, like a heart attack," Alberto Gutierrez, director of the Office of In Vitro Diagnostics and Radiological Health in the FDA's Center for Devices and Radiological Health, said in an agency news release.

Yoga May Cut Heart Disease Risk Factors

Review found those who took yoga classes saw improvements in blood pressure, cholesterol, weight.

Yoga has long been believed to improve overall health, but a growing body of evidence shows the ancient practice may also help the heart, a new review finds.
In fact, the benefits were similar to those of conventional exercise such as brisk walking, said lead researcher Paula Chu, a doctoral candidate at Harvard University's Health Policy Program in Boston.
The review, of 37 clinical trials, found that people randomly assigned to take yoga classes saw improvements in their weight, blood pressure and cholesterol.
"This finding suggests that [people] who are physically limited in some way do not have to 'pound the pavement' in order to improve their cardiovascular risk profile," Chu said.
Still, studies so far have varied in quality and been relatively small and short-term, Chu's team reports in the Dec. 16 issue of the European Journal of Preventive Cardiology.

Is BPA Bad for Your Heart?

Some evidence shows ill effects of the chemical, but the case is far from closed.

The container you use may expose you to the chemical known as BPA.

HIGHLIGHTS

Bisphenol-A (BPA) looks like estrogen to the body.

Early animal studies suggest BPA can affect heart function.

France will ban BPA from all products coming into direct contact with food as of 2015.

A new report, published in Hypertension in December 2014, links the chemical bisphenol-A (BPA) from canned foods to spikes in blood pressure. The study has drawn attention to potential heart risks associated with the chemical.
You’ll find BPA in plastic bottles, food containers, the linings of cans, and even some cash register receipts. A 2005 study of the general U.S. population detected BPA in the urine of more than 95 percent of people tested.

New health benefits associated with hempseed oil

Hemp is a crop full of oils with potential health benefits, according to a new study in the Journal of Agricultural and Food Chemistry.

A derivative of cannabis (marijuana), hemp has been used for millennia in textiles, medicine and food, by people all over the world.

Despite this, hempseed has been banned in North America since the 1930s, when all varieties of cannabis were made illegal due to its tetrahydrocannabinol (THC) content. THC is the compound that induces the "high" in recreational use of cannabis.

However, hemp with low THC content (0.3%) has been legalized by the European Union, and the global economic market for low-THC hemp - used in medicines, papers and fabrics - is valued at $100-200 million annually.

Researchers analyzed a portion of hempseed oil to see what beneficial qualities it may have. They found that some of its components are effective at promoting good health. These include sterols, aliphatic alcohols and linolenic acids.

'Rise of saturated fat in diet does not raise fats in blood'

A New controlled diet study has found that increasing the levels of saturated fat in the diet does not lead to increased levels of saturated fat in the blood. However, increasing the amount of carbohydrates in the diet was found to raise the levels of a fatty acid associated with diabetes and heart disease.

Diets full of high carbohydrate foods such as cookies could increase the risk of heart disease, according to research.

Levels of palmitoleic acid were reduced with lowcarbohydrate intake and increased as the participants consumed progressively larger amounts of carbohydrates over the course of the study.

According to senior author Prof. Jeff Volek, the study, "challenges the conventional wisdom that has demonized saturated fat and extends our knowledge of why dietary saturated fat doesn't correlate with disease."
