How well do you know about heart attack?

It is so sad people are dying every minute due to heart attack, some of these deaths would have been prevented with proper awareness. Here are some things you should know about the disease.

What happened during heart attack
In a heart attack, blood supply to the heart muscle is interrupted and heart muscle cells start to die, which may cause chest pain—but sometimes it doesn't, especially in women. Most heart attacks build up slowly, with milder pain or discomfort.

How will I know if I'm having a heart attack? Seek medical help immediately if you have the slightest suspicion that you may be having a heart attack. Most heart attack deaths happen in the first hour after an attack, waiting several hours before seeking for help could be deadly! If you have any of the following symptoms:
Chest discomfort: Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and then comes back. It may feel like an uncomfortable level of pressure, squeezing, fullness, or pain.
Upper body discomfort: Pain in one or both arms, the back, neck, jaw, or stomach could signal a problem.
Shortness of breath: This symptom may occur with or without chest discomfort.
Other signals: Pay attention to body symptoms you don't normally experience, such as breaking out in a cold sweat, nausea, lightheadedness, overwhelming fatigue, or a feeling of impending doom. (These signs are especially common in women.)
When does heart attack likely strike?
A heart attack can strike at any time, but it occurs most frequently in the early hours of the morning. Heart attacks are 40 percent more common between 6 a.m. and noon than at other times of the day. Similarly, sudden cardiac deaths are 29 percent more common in the morning.
What should be done in case it strikes?
Call for an ambulance immediately, and stay calm. Then, sit or lie still and slowly chew one 300 mg aspirin tablet—aspirin helps minimize heart damage or development of a dangerous blood clot by reducing the 'stickiness' of the platelets that play an important part in blood clotting. Don't eat or drink anything, and phone a relative, neighbor, or friend to come wait with you.
