To find out how aspirin works fastest, researchers in Texas asked 12 volunteers to take a standard 325-mg dose of aspirin in three different ways: by swallowing a tablet with 4 ounces of water, by chewing the tablet for 30 seconds before swallowing it, or by drinking 4 ounces of water with Alka-Seltzer. But since the clot grows minute by minute, time is of the essence. Only a tiny amount is needed to inhibit all the platelets in the bloodstream in fact, small amounts are better than high doses. As a result, muscle cells die - and it's a heart attack.Īspirin helps by inhibiting platelets. If the blockage is complete, it deprives a portion of the heart muscle of oxygen. A clot, or thrombus, builds up on the ruptured plaque. Platelets are the tiny blood cells that trigger blood clotting. When they do, they attract platelets to their surface. Relatively small plaques, which produce only partial blockages, are the ones most likely to rupture. Most heart attacks develop when a cholesterol-laden plaque in a coronary artery ruptures. But how can a humble aspirin tablet add to high-tech medicine, and why is speed so important?
It's modern cardiology at its best, and it has improved considerably the outlook for heart attack victims. In the hospital, doctors will take EKGs and blood tests to see if you are having a heart attack if so, they will usually try to open the blocked artery with an angioplasty and stent or, if that's not available, with a clot-busting drug. The paramedics can give you oxygen and medication, and they'll monitor your blood pressure and heart rhythm to forestall complications as they speed you to the ER. The reason you need aspirin is the same reason you should call 911 without delay: A heart attack is a dynamic event, and early intervention can limit the damage. You also need to get some aspirin into your system quickly - but should you chew the tablet or swallow it?
