Since people with hypertension and heart disease are at increased risk for a heart attack, it's a good idea to know the warning signs and have a plan if you should experience the symptoms. The American Heart Association lists these warning signs of a heart attack:

• Chest discomfort - Uncomfortable pressure or a sensation of squeezing or fullness, usually in the center of the chest, lasting for more than a few minutes or going away and then returning.
• Discomfort elsewhere in the upper body - in one or both arms, or in the back, neck, jaw, or stomach.
• Shortness of breath - may occur before the chest discomfort or accompany it.
• Others signs include breaking out in a cold sweat, nausea, or light-headedness.

If you have any of these symptoms - even if you're not sure - call 911 at once. Timing is critically important, and an ambulance trip to the hospital ER is your best means of getting fast help. Next week we'll look at what to expect once you get to the ER.
