What Happens during a Heart Attack?

More than a million Americans have heart attacks each year. The heart muscle, for nourishment requires a constant supply of oxygenated blood and it is the coronary arteries that provide the heart with this critical blood supply. The arteries become narrow and blood cannot flow as well as they should if an individual has coronary artery disease.  Fatty matter, calcium, proteins, and inflammatory cells build up within the arteries to form plaques of different sizes. The plaque deposits are hard on the outside and soft and mushy on the inside.

With the plaque being hard, the outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come to the area, and blood clots form around the plaque. If a blood clot totally blocks the artery, the heart muscle becomes "starved" for oxygen which causes death of heart muscle cells within a very short time, causing permanent damage. This is a heart attack.
It is quite unusual but a heart attack can also be caused by a spasm of coronary artery.

Heart Attack Symptoms:

1.      Rapid or irregular heartbeats
2.      Discomfort, pressure, heaviness, or pain in the chest, arm, or below the breastbone
3.      Discomfort radiating to the back, jaw, throat, or arm
4.      Sweating, nausea, vomiting, or dizziness
5.      Shortness of breath, anxiety, weakness
Some people may have a heart attack without having any symptoms (a "silent" myocardial infarction). A silent MI can occur in anyone, but diabetics are more susceptible it.
Tests to Diagnose a Heart Attack:
        I.            Electrocardiogram or ECG
      II.            Echocardiography
    III.            Cardiac catheterization
    IV.            Blood Tests

If an individual is struck with a heart attack, quick treatment to the blocked artery would be essential in order to lessen the amount of damage. One should immediately dial 911 for the emergency medical services. The best time to treat a heart attack is within one to two hours of the first onset of symptoms. Waiting longer not only increases the damage to the heart but also reduces the chances of survival.

Chest discomfort can be described in many ways which can in the chest or in the arms, back, or jaw. Do take notice if you have the symptoms and do not overlook any symptom.
