Heart attack and its Symptoms

Heart attack… and its Symptoms

A heart attack mainly 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.

What causes a heart attack?

In the period of time, cholesterol plaques are deposited in the walls of the arteries. This plaques cause narrowing of the inner channel or lumen of the artery and hardening of the arterial walls. Thus arteries cannot supply enough blood to support normal function of the parts of the body. When the heart muscle doesn’t get sufficient blood supply it will cause ache in the muscle. This ache is known as Angina.

Incase if the plaque ruptures it can cause blood clot within the blood vessel and suddenly block the flow of blood. When the blood supply fails to reach various part of the heart the muscle dies. This is known as heart attack or myocardial infarction (MI).

Signs and symptoms of a heart attack

Sweating, Severe pain extending from your chest to your shoulder, arm, back, or can even to extend to your teeth and jaw, Fullness, pressure, or even a squeezing pain in the center of your chest that ends for more than a few minutes, Progressive episodes of chest pain, Prolonged pain felt in the upper abdomen, vomiting and nausea, Shortness of breath, Faintness, close sense of doom.

Signs and symptoms in all the people who have experience heart attack need not be in the same degree. Some show no symptoms at all.

A heart attack can occur irrespective of time and place, while you are resting or even you are at work or play. Some times heart attack show signs and symptoms in advance, but some times it happens suddenly. A recurrent chest pain or angina that is triggered by exertion can be relieved by rest. “Cardiac ischemia” or angina is caused by deficient blood flow to the heart.
