Heart Attack - What when why
A heart attack can happen when there is a sudden complete blockage of an artery that supplies blood to a section of the heart.
The heart is a muscle, and it requires a good blood supply to keep it healthy and in working condition. As we get older though, the smooth inner walls of the hearts arteries that supply the blood can become impaired and narrow due to the build up of fatty substances, called plaque.
A heart attack happens when a blood clot completely blocks the passage of blood flow and seriously reduces blood flow to a particular section of the heart muscle. This also results in patients experiencing chest pain that can last longer that 10 minuets.
As a result, some of the heart muscle starts to die due to lack of oxygenated blood. The longer the blockage of the hearts arteries is left untreated, the more the heart muscle is going to get damaged.
The common underlying causes of a heart attack is coronary heart disease.
Some people don't know they have coronary heart disease until they have a heart attack unfortunately. For some others, a heart attack can happen after weeks, months or even years of having coronary heart disease.
Heart attack warning signs can vary between people.

• Pain in back,

A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.
Symptoms include tightness or pain in the chest, neck, back or arms, as well as fatigue, lightheadedness, abnormal heartbeat and anxiety.
Women are more likely to have atypical symptoms than men.
Treatment ranges from lifestyle changes and cardiac rehabilitation to medication, stents and bypass surgery.
