花姐,心肌梗塞是因为冠状动脉狭窄堵塞后心肌缺血(氧)造成心肌细胞死亡的一个急症.

在健康坛已经讨论过多次.这些网络上似是而非的急救帖都是很能迷惑人心的,热传热议.点击率极高,转贴/收藏的人也极多.
冠状动脉在心脏上,你拍打得到吗?靠拍打手臂血管里有多大的力能冲掉冠状动脉里常年累积的粥样脂块?用脑子想一想?唯一能帮助的就是基本救命术---心肺复苏术CPR.

同胞们, 不知道怎么做时, 请 ** call 911 ***

Heart attack first aid: MedlinePlus Medical Encyclopedia

First Aid

If you think someone is having a heart attack:

• Have the person sit down, rest, and try to keep calm.
• Loosen any tight clothing.
• Ask if the person takes any chest pain medication for a known heart condition, such as nitroglycerin, and help them take it.
• If the pain does not go away promptly with rest or within 3 minutes of taking nitroglycerin, call for emergency medical help.
• If the person is unconscious and unresponsive, call 911 (or your local emergency number), then begin CPR.
• If an infant or child is unconscious and unresponsive, perform 1 minute of CPR, then call 911.

DO NOT

• Do NOT leave the person alone except to call for help, if necessary.
• Do NOT allow the person to deny the symptoms and convince you not to call for emergency help.
• Do NOT wait to see if the symptoms go away.
• Do NOT give the person anything by mouth unless a heart medication (such as nitroglycerin) has been prescribed.

When to Contact a Medical Professional

Call 911 or your local emergency number immediately if the person:

• Does not respond to you
• Is not breathing
• Has sudden chest pain or other symptoms of a heart attack

Prevention

Adults should take steps to control heart disease risk factors whenever possible.

• If you smoke, quit. Smoking more than doubles the chance of developing heart disease.
• Keep blood pressure, cholesterol, and diabetes in good control and follow your doctor's orders.
• Lose weight if obese or overweight.
• Get regular exercise to improve heart health. (Talk to your doctor before starting any new fitness program.)
• Eat a heart-healthy diet. Limit saturated fats, red meat, and sugars. Increase your intake of chicken, fish, fresh fruits and vegetables, and whole grains. Your health care provider can help you tailor a diet specific to your needs.
• Limit the amount of alcohol you drink. One drink a day is associated with reducing the rate of heart attacks, but two or more drinks a day can damage the heart and cause other medical problems.
