What is a Heart Attack

Heart Attack

What is a heart attack?
A heart attack happens when blood flow to a part of your heart muscle is suddenly blocked.
Sometimes heart attacks happen when the heart needs more oxygen than the blood vessels can provide. This might happen, for example, during hard exercise such as shoveling snow.
The heart is a muscle like other muscles in your body. It needs oxygen, which it gets from the blood in blood vessels. The blood vessels that bring blood to the heart are called coronary arteries. A blood clot in one of these arteries can block the flow of blood to the heart muscle and cause the heart to stop working right. If the block lasts for many minutes, part of the heart can be injured.
The risk of a heart attack increases as you get older. Plaques (patches of cholesterol) may form in the arteries. This makes the arteries narrower inside. Blood clots may more easily form in a narrowed artery and block it.
Both men and women have heart attacks.
What are the symptoms?
You may:
• Feel pressure or pain in the middle of your chest.
• Feel pain in your shoulder, arm, abdomen, or jaw.
• Feel short of breath.
• Sweat.
• Have nausea.
• Feel weak or lightheaded.
• Look pale.
You can have a heart attack when you are resting or when you are exercising. You may think you just have an upset stomach. However, it’s important to get medical help as soon as you can. Don’t wait.
How is it diagnosed?
The health care provider checks you over. He or she will ask what you are feeling and about your medical history. You may have some tests to see how well your heart is working.
How is it treated?
You may stay in the hospital about 2 to 6 days.
• Your health care provider will give you medicine to dissolve blood clots.
• You may be given other medicines.
• You may be in an intensive care unit.
• You may be given oxygen to make it easier for you to breathe.
• You may need to have an operation to open up or bypass the blocked area of the artery.
As you get better, your health care provider will help you work out a program to take care of yourself.
