Know the warning signs of heart attack
Two-thirds of Americans can't identify the signs of a heart attack and say what needs to be done when one strikes. That's the unsettling news from a survey done by the Centers for Disease Control and Prevention.
The longer you wonder "Am I having a heart attack?" or "Am I having a stroke?" the longer your heart or brain cells may be cut off from life-sustaining oxygen. (You don't get much time to think about a cardiac arrest — a few seconds after it hits, you're unconscious.)
It's hard not to wonder, though. Heart attacks aren't always the obvious, chest-clutching, elephants-sitting-on-my-chest events portrayed on television or in articles about the warning signs of a heart attack. The signs can be subtle, like heaviness in the arms, unusual fatigue, or unexpected nausea. A heart attack can be mistaken for the flu, indigestion, or a strained muscle. Strokes can be equally sneaky. A general rule: if you think you are having a heart attack or stroke, act on that suspicion.
Fast action is essential. The sooner you get to the hospital, the greater the chances that doctors can restore blood flow to your heart or brain and thus minimize permanent damage to these key organs.
Here's a list of warning signs suitable for posting on the refrigerator or near the telephone. It covers all three of the major cardiovascular catastrophes. Before putting it up, take a minute or so to read the list a few times. A small investment of time now might help you, someone you love, or even a stranger survive one of these disasters and live a long life afterward.
Know the signs
Every minute counts when a heart attack, stroke, or cardiac arrest is under way. Knowing the signs can translate into getting to the hospital — and getting treatment — fast enough to do the most good. If you recognize any of the signs below, call 911 or your local emergency number right away. Don't call your doctor's office or drive yourself to the hospital.
