A heart attack occurs when blood flow to a section of heart muscle becomes blocked. If the flow of blood isn’t restored quickly, the section of heart muscle becomes damaged from lack of oxygen and begins to die.During a heart attack, if the blockage in the coronary artery isn’t treated quickly, the heart muscle will begin to die and be replaced by scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.
Heart attacks can cause a wide range of symptoms, from mild to intense. Women, the elderly, and people with diabetes are more likely to have subtle or unusual symptoms.
-Cold sweat
-Light-headedness
-Nausea
-Numbness, aching, or tingling in the arm (usually the left arm)
-Shortness of breath
-Weakness or fatigue, particularly in the elderly
-Women are more likely than men to have symptoms of nausea, vomiting, fatigue, back or jaw pain, and shortness of breath, either alone or with chest pain.
the first aid is
-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.
-Help the person take the medication (usually nitroglycerin, which is placed under the tongue).
-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.
