There are a number of different causes of heart attack. Some can occur quickly, while others can take a long time to develop. However, most heart attacks are caused by coronary artery disease. The risk of developing the disease increases with age, as well as obesity, smoking, and other factors.

If a blood clot blocks the flow of blood to your heart, you might experience one or more of the following symptoms: headache, shortness of breath, and chest pain. You should seek medical attention immediately. In most cases, the pain will be temporary. However, if it persists, you may have a heart attack.

Heart attacks can be quite frightening. The first symptoms you may notice are mild discomfort and a tightening in the chest. This is most often accompanied by nausea or a light sweat. Depending on the severity of the attack, you might also feel a pressure or fullness in the chest.

A heart attack occurs when your heart muscle is deprived of oxygen and nutrients. This lack of oxygen causes cells in your heart to die. Your heart will continue to work despite the damage, but only if the oxygen supply is restored in a timely manner.

When a blood clot blocks the flow to your heart, your body sends a rush of platelets to clot the artery. After the clot is removed, your body begins to rebuild the affected area. During this process, healthy heart tissue is replaced with scar tissue. However, the scar tissue doesn't pump as efficiently as the healthy muscle tissue. It takes up to eight weeks for your heart to recover.

In addition to a blood clot, a spasm of your coronary artery can cause a heart attack. Spasms can happen to any artery, and they can occur even without coronary artery disease.

The exact location of your heart attack will determine how well you recover. If the heart is severely damaged, it might stop beating completely. Alternatively, your heart might go into a normal rhythm.

Although there is a wide range of symptoms associated with a heart attack, many heart attack victims have warning signs. For example, chest pain can be triggered by exertion, stress, or emotional pressure. Other areas of the upper body can also be affected.

In addition to experiencing any of these symptoms, you may experience a sudden loss of energy or difficulty breathing. A numbness or tingling in your hands, arms, or neck could be a sign of a heart attack.

When your heart fails to beat, the blood supply to the brain is disrupted. The heart muscles may also begin to die. Symptoms vary greatly from person to person, but the earliest warning you should be looking out for is recurrent or intermittent chest pain.

There are several ways to prevent a heart attack, including a healthy diet, exercising regularly, and quitting smoking. However, if you've recently suffered a heart attack, you need to get the proper treatment. Getting the help you need can reduce the effects of the attack and prolong your life.
