Symptoms Of Myocardial Infarction

Symptoms of Myocardial Infarction include:

• Discomfort, pressure, heaviness, or pain in the chest, arm, or below the breastbone
• Discomfort radiating to the back, jaw, throat, or arm
• Fullness, indigestion, or choking feeling (may feel like heartburn)
• Sweating, nausea, vomiting, or dizziness
• Extreme weakness, anxiety, or shortness of breath
• Rapid or irregular heartbeats

During a heart attack, symptoms last 30 minutes or longer and are not relieved by rest or nitroglycerin under the tongue.
Some people have a MI without having any symptoms (a "silent" myocardial infarction). A silent MI can occur in any person, though it is more common among diabetics.
After a MI, quick treatment to open the blocked artery is essential to lessen the amount of damage. At the first signs of a MI, call for emergency treatment. The best time to treat a MI is within one to two hours of the first onset of symptoms. Waiting longer increases the damage to your heart and reduces your chance of survival.
Keep in mind that chest discomfort can be described many ways. It can occur in the chest or in the arms, back, or jaw. If you have symptoms, take notice. These are your MI warning signs. Seek medical care immediately.
