A new bio-marker test can detect a heart attack.

It detects markers, or characteristics in the blood that are linked to the risk of having a heart attack.

If a patient has all three of the abnormal bio-markers, they have an 18 percent chance of having heart attack within a year.

Doctos say the research is remarkable because a person's health history isn't always the answer.

"You can't use genetics to sensitively distinguish who is at risk in the next year or two," according to a cardiologist involved in the study. "It could tell you who's at risk over the next 20 years, but what the physician also has to know and perhaps even more importantly, is who's at risk in the next few months."

Researchers hope the test will be available for patients within the next few years.

Breastfeeding benefits

 Breastfeeding is known to help ward off infections among infants, but a new U.S. study suggests that protection may be much longer lasting.

Studies show as a child grows, they are less likely to have ear, sinus or throat infections - if they were breastfed.

According to research, the longer a child was breastfed during their first year, the lower their risk was of those infections by the time they were six years old.

Following-up on babies who were part of a breastfeeding study in 2005-07 provided a unique opportunity to see if there were long-term benefits from having been breastfed.

The researchers contacted 1,281 of the mothers in 2012, when their children were about 6 years old, and asked about the number and types of common infections the children had in the previous 12 months.

They also asked how many times the child had been to the doctor’s office.

Anxiety drugs linked to Alzheimer's?

Certain drugs that help treat anxiety or lack or sleep have been linked to Alzheimer's, according to a study.

According to experts, long term use of drugs like Xanax and Valium can increase a person risk for Alzheimer's. Researchers are suggesting the risk could increase by up to 51 percent.

Previous studies have linked the drugs to memory and cognitive problems, but primarily in those taking them short term.

According to published reports, in order to rule out the possibility that it was happening the other way around—that Alzheimer’s was causing a rise in insomnia and anxiety—the authors focused on people who had been prescribed sleeping and anxiety meds more than five years before they were diagnosed with Alzheimer’s.

It is not clear why the drugs may increase the risk.
