About Heart Attact
What is a heart attack?
A heart attack (also known as a myocardial infarction or MI) is the damage and death of heart muscle from the sudden blockage of a coronary artery by a blood clot.
Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle. I
njury to the heart muscle causes chest pain and chest pressure sensation. If blood flow is not restored to the heart muscle within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur.
Muscle continues to die for six to eight hours at which time the heart attack usually is "complete." The dead heart muscle is eventually replaced by scar tissue.
Watch out for these signs
Heaviness or pressure over the chest while at rest or minimal exertion, associated with restlessness, perspiration, radiation of pain to jaw, back, left arm.
Breathlessness without any chest discomfort, especially in diabetics.
Abdominal pain and bloating are usually acidity-related problems, but if the symptoms are more than usual in severity or are associated with other symptoms, take them seriously.
Heart attack is caused when a clot completely blocks a blood vessel in the heart. The primary aim is to get rid of this clot as soon as possible; otherwise, that part of the heart dies.
Even if there is a slight suspicion that the symptoms could be of a heart attack, chew a 300/325mg of aspirin tablet immediately; it helps dissolve the clot. Once you are at the hospital, the doctors will try to get rid of the clot, either with the help of a very powerful clot buster medicine [thrombolytic medicines] or with a procedure called primary angioplasty.
Although both modalities have advantages and disadvantages, primary angioplasty is the preferred therapy in most scenarios. Apart from this, other supportive therapy also gets initiated simultaneously.
