Heart Disease - The heart is the center of the circulatory system or cardiovascular system. The heart pumps blood to all cells of the body through blood vessels. The blood carries oxygen that cells need. Cardiovascular disease is a group of disorders that occur when the heart and blood vessels are not working as they should.
These are some of the problems associated with cardiovascular disease:
Arteriosclerosis and Atherosclerosis: also known as hardening of the arteries. Arteriosclerosis in the arteries become thickened and lose flexibility. People with atherosclerosis have an accumulation of cholesterol and fat that causes the arteries narrower, so that the amount of blood flowing is smaller. Deposits known as plaque.
- Angina : People with angina feel chest pain, this means that the heart does not receive enough blood.
- Stroke or stroke : When part of the brain does not get enough blood due to a blood clot or a ruptured blood vessel.
- Heart attack : when a blood clot or other blockage cuts off the blood flow to part of the heart.
Heart disease is not contagious - you can not contract like the flu or a cold. Rather, there are certain things that increase the chances of a person developing cardiovascular disease. Doctors call these risk factors. Some of these risk factors, such as being an older person or have relatives with the same problems, can not be counteracted. But there are certain risk factors that you can control. Smoking, high blood pressure, overweight and do not exercise can increase the risk of developing cardiovascular disease.
Signs of heart disease
Many people do not realize they suffer from cardiovascular disease until they have chest pain, a heart attack or stroke. These types of problems often require immediate attention and the person needs to go to the emergency room of a hospital. If not an emergency and the doctor suspects the person could have cardiovascular disease, you can perform tests to determine how they are working the heart and blood vessels. These tests include:
Electrocardiogram: This test records the electrical activity of the heart. The physician connects the patient to a monitor and observe the machine to see the heartbeat and determine if it is normal.
Echocardiogram : This test uses sound waves to diagnose heart problems. The waves bounce off the parts of the heart and create an image thereof is displayed on a monitor.
Stress test : For this test, the person exercises while the doctor watches the electrocardiogram machine to see how it reacts to the heart muscle.
Catheterization : This test uses a long, thin tube that is inserted into the patient 's body to inject a special dye. It can locate narrowed arteries due to the buildup of plaque and other problems detect areas.
Carotid artery scan : This test uses sound waves to detect the presence of blockages in the carotid artery, a large blood vessel in the neck that supplies blood to the brain.
If the physician determines that a patient has cardiovascular disease, talk with the patient about how it can help quitting smoking, losing weight, eating a healthy diet and exercise. It could also be necessary for the person to take drugs, you do surgery, or both.
There are different types of surgery for heart and blood vessels. Some of them are :
Angioplasty : the blocked blood vessel using a like a balloon at the narrowest point of an artery device opens. The doctor may also insert a stent ( stent ), which is a tiny stainless steel tube that keeps the vessel open and ensures that remain free of blockage.
Atherectomy : This involves removing plaque from an artery, for blood to flow freely.
Coronary Bypass Surgery : This involves taking part of an artery or vein from another part of the body (arm or leg) and use it to channel the passage of blood around a blocked artery in an area.
Pacemaker : A pacemaker is a small electronic device that is placed inside the body to regulate the heartbeat.
Valve replacement : The surgeon can replace a damaged heart valve or malfunctioning.
Carotid endarterectomy: During this procedure, the surgeon removes plaque deposits in the carotid artery to prevent stroke.
If someone you know is going to be subjected to one of these operations you may feel restless. The good news is that these surgeries can help prevent heart attacks, strokes and other disorders. The amount of time that the person will need to pass in the hospital will vary, depending on the operation and health. The person may feel tired and exhausted after surgery, but you can help making a card that says "Get Well" and visit her.
Can children develop heart disease?
Generally, children do not have symptoms of heart problems or blood vessels while they are young. But if they start to develop healthy heart habits now, children can reduce the likelihood of having to worry about the future of cardiovascular disease. So what should you do? For starters, do not smoke. And be sure to eat healthily, exercising and maintaining a healthy weight. Your heart and blood vessels will thank you later!
