An Aspirin a Day May Not Keep Heart Attacks Away

An aspirin a day will keep the doctor away. At least that's what many people believe. For years it's been said by doctors and even on TV commercials that an aspirin could prevent heart attacks, but it doesn't work for everyone.

According to a new study it won't work for 25 percent of people. Dr. David Hector, a cardiologist at Trinity Mother Frances Hospital explains. "The aspirin actually does not reduce the levels of the Thromboxane A2, thus keeping the blood thicker."

Thromboxane A-2 is in all of us. But in most people an aspirin will prevent the chemical from forming. . But some people are aspirin resistant and that means even though they're taking their daily aspirin, it isn't thinking their blood or helping their arteries to open widely enough for blood to flow through.

So are you at risk? There are only two ways to know for sure, according to Dr. Hector. "The only way to know if you have Thromboxane in your system would be to test your urine or test your blood." Dr. Hector says a urine test is the cheaper option.

If you are concerned you may be aspirin resistant talk to your doctor and even if you do have high levels of Thromboxane in your body don't stop taking aspirin.A higher dose of aspirin may be all you need or your doctor may put you on more medication like blood thinners.
