- Heart disease and heart attacks: that every woman should know
- How to protect yourself
There are more than fifty types of heart disease, the most common of them - coronary heart disease. From the induced heart attack deaths each year several million people. Some other types of heart disease - cardiomyopathy, arrhythmia, congestive heart failure, stroke,
Stroke - a serious brain injury
.
How the heart works
To understand heart disease, you need to know exactly how to work the body. Heart and blood vessels - is the transportation system that delivers all the cells of the body the materials they need and outputs of these wastes. By moving this system nutrients, oxygen, carbon dioxide, hormones, lipids, and many other substances necessary for the functioning of the body.
Almost devoid of oxygen the blood moving through the veins in the chamber on the right side of the heart. From there, the blood enters the lungs, where the blood is saturated with oxygen and carbon dioxide is released from. Oxygenated blood flows into the left chamber of the heart, and then - to the aorta, the large blood vessels of the body where the arteries, veins and smaller blood vessels gets to all parts of the body.
Of course, the heart muscle, as well as all other muscles to do their job, require oxygen and nutrients. Surprisingly, the heart is not used as a power supply blood that is pumped continuously through it. Just like all the other muscles in the body, the heart gets nourished his blood through the coronary arteries, which are the first branches of the aorta.
Types of heart disease
Coronary heart disease is caused by a narrowing or blockage of the coronary arteries that supply the heart with oxygen and nutrients. The result of coronary heart disease could be angina, myocardial infarction and sudden cardiac arrest.
A stroke occurs when the narrowed or blocked blood vessels that supply oxygen to the brain. Peripheral vascular disease develops in a similar way, but in the arteries that supply oxygen and nutrients to the lower extremities.
Congestive heart failure is characterized by the weakening of the results of the heart muscle, causing it fails to pump blood properly. Its common symptoms are shortness of breath, inability to withstand even minor physical exertion, and swelling of the legs. Congestive heart failure may be the result of damage caused by a heart attack or cardiomyopathy (heart muscle disease).
Arrhythmia (abnormal heart rhythm) may be chronic and relatively harmless, but in some cases it promotes congestive heart failure, and may also be a contributing factor of sudden cardiac death.
Cardiomyopathy occurs when the heart muscle loses its ability to pump blood properly. This disease can be caused by atherosclerosis of the coronary arteries, although the exact cause is often not clear.
Less common disease affecting the inner and outer lining of the heart - endocarditis and pericarditis.
Congenital heart defects affect any structures of the heart and can be of varying severity. Some of them are detected almost immediately after birth; sometimes newborns have to do heart surgery. In some cases, these diseases manifest themselves only in adolescence or even later.
Heart attack
A heart attack occurs when a blood clot blocks the blood flow through the coronary artery - a blood vessel supplying blood to part of the heart muscle. As a result, blood flow disturbances of the heart muscle can be damaged or destroyed.
A heart attack, also called myocardial infarction, can lead to death. Often this is because people confuse their symptoms with symptoms of less serious diseases, such as dyspepsia, try to endure and go to the doctor too late. For several years, treatment of heart attack significantly improved. It is critical to quickly recognize the symptoms of a heart attack and immediately call an ambulance.
Symptoms
Common symptoms of a heart attack:
- Sharp pain in the left side of the thorax; because this pain is not similar to other types of pain experienced by her people often immediately realize that it hurts the heart, but a heart attack is not always accompanied by such symptoms;
- Feeling of tightness or fullness in the center of the chest lasting several minutes or more;
- Chest pain, which is given in the shoulders, arms, back, and even in the teeth and jaws;
- Increased episodes of pain in the heart;
- Prolonged pain in the upper abdomen;
- Shortness of breath;
- Increased sweating;
- Fainting;
- Nausea and vomiting.
In addition, a heart attack can cause lightheadedness or dizziness
Dizziness - if the ground is slipping from under his feet
and unusually severe fatigue - these symptoms are most common for women.
It is important to understand that heart attacks do not always cause the same symptoms and the same symptoms in different people can be equally intense. Sometimes the symptoms are very weak, or even completely absent.
A heart attack can happen at any time - at work, during exercise, or when you are resting. Someone has a heart attack begins suddenly, but many people have warning signs appear in a few hours, days or weeks in advance. The earliest sign of impending heart attack can be a periodic pain in the heart
Pain in the heart - always consult a doctor
Caused by physical exertion, and retreating during the holidays. Angina is caused by a temporary reduction in blood flow to the heart.
Often confused with a heart attack condition in which the heart suddenly stops. Sudden cardiac arrest occurs when electrical interference signals disturb the heart and stop the flow of blood to the rest of the body. A heart attack is the most common but not the only, cause of sudden cardiac arrest.
If you suspect that you have a heart attack, call an ambulance immediately. If this is for some reason not possible, have someone drive you to the nearest hospital. Get behind the wheel yourself only as a last resort.
If the doctor has prescribed nitroglycerin, take it while waiting for an ambulance. Take aspirin if recommended by a doctor or ambulance dispatcher. Aspirin thins the blood and can reduce the damage that will be done to the heart resulting in a heart attack.
If you are near a person who has lost consciousness, and you suspect that he had a heart attack, call an ambulance immediately. While you're waiting the arrival of the doctors make the victim heart massage.
Causes
A heart attack occurs as a result of narrowing of the arteries that supply the heart with oxygen-rich blood. This may occur, for example due to accumulation of cholesterol on the walls of the coronary arteries - disturbances, called atherosclerosis.
During a heart attack one of the fatty plaques can rupture and discontinuity is formed at the site of a blood clot. If a clot large enough, it can completely block blood flow through an artery that leads to the death of heart muscle tissues as a result of oxygen deficiency.
A less common cause of heart attack are the coronary artery spasms, also resulting in impaired blood flow to the heart muscle. The reasons for such a spasm may be some drugs, such as cocaine. A heart attack can also occur as a result of rupture of a coronary artery, as well as getting into the coronary artery blood clots in other parts of the body.
Heart attack is the final stage of the process, which typically takes several hours. With every minute most of the tissues of the heart muscle is damaged or dies as a result of oxygen starvation. However, if the time to restore blood flow, heart damage can be limited or prevented.
Risk factors
Factors that increase the risk of heart attack:
- Age. Men older than 45 and women older than 55 years are at risk of heart attack more than younger men and women.
- Smoking, both active and passive continuous promotes damage to the internal walls of the arteries and thus the deposition of cholesterol on them. Smoking also increases the risk of blood clots that can cause heart attack.
- Diabetes is characterized by the body's inability to produce enough insulin
The principles of action of insulin - the science of saving lives
. Diabetes is most common in middle-aged and / or overweight. This disease increases the risk of heart attack.
- High blood pressure. Over time, high blood pressure can lead to damage of the arteries supplying the heart with oxygen. The consequence of this could be a heart attack.
