Your odds of suffering a deadly heart attack just plummeted. That’s because scientists have created a new blood test that they say can predict whether or not you’ll have a heart attack two weeks in advance, giving you crucial time to take lifesaving medication to prevent it.

Doctors say that most heart attacks happen when fatty deposits in your arteries burst open, and a blood clot forms to seal the break. The problem is if the clot is too big, it blocks off blood flow, triggering a heart attack.

Up until now, if you felt like you were experiencing heart attack symptoms, doctors could only check for problems in your heart. And unless you were suffering an attack at that moment, your heart will appear OK. That’s why a lot of people are tragically sent home from the hospital with a clean bill of health, only to suffer a heart attack days later. In fact, every minute, someone dies from a heart attack.

So, here’s where the brand new test comes in. Doctors take a sample of your blood, then scour it for abnormal cells that have flaked off fatty arteries. If you have a lot of abnormal cells, then odds are you’re a ticking time bomb, and doctors will put you on preventative medication ASAP.

Researchers say that the test has a 90% accuracy rate, but probably won’t be available for another year.

In the meantime, experts suggest learning the heart attack warning signs, and heading to the hospital as soon as they hit. Gentlemen, the #1 sign for you is chest pain. And ladies, many times you won’t feel chest pain before a heart attack. Instead, your top symptoms are fatigue, shortness of breath, and indigestion.
