Definition and cause

The heart is supplied with blood from two coronary arteries, departing from hovedpulsåren (aorta). Crane Pulse Årerne runs outside the heart and branches out, so when the entire heart. The heart consists of a special type of muscle, and heart to be able to supply the entire body with blood, it is crucial that the crane pulse arteries are in a position to supply the heart muscle with nutritious and iltmættet blood.

Atherosclerosis (or with a better word åreforsnævring) of coronary arteries may lower pulse oxygen supply to the heart.

With age, all people develop stiffer arteries. The overwhelming reason for stiffer arteries is called atherosclerosis, which in English is called arteriosclerosis.

Already early in life may be so-called fatty streaks in coronary heart rate years. Further Develops this themselves, can yield streak together to larger areas and form a so-called aterom (hence the name atherosclerosis, which meanshard aterom). Ateromet consists of fat and inflammatory cells and may have a thin forkalket be.

The uneven surface of ateromet makes platelets in the blood more easily becomes lodged and pile up here. They provide atricyclic(a thrombus). It leads to further narrowing of the artery. Clumps of platelets can grow so large that the enclosures for oxygen supply to the heart, coronary artery supplies.

It has several factors that are associated with an increased risk of developing arteriosclerosis:

  • Smokingis strongly associated with the disease, and of all ages equal risk significantly reduced by stopping smoking.

  • Male.Males develop arteriosclerosis of coronary heart rate around years. 10 years earlier than women.

  • Hereditary conditions. There is an increased risk if arteriosclerosis occurs in the family.

  • Lack of exercise.Even ½ -1 hour daily time is preventive against arteriosclerosis.

  • Obesity.

  • Increased blood cholesterol. Especially so-called LDL-cholesterol is bad.

  • Diabetes (diabetes),Type 1 and Type 2
  • Regrhøjet blood pressure.

  • Stress.

Many bodies have blood supply from several arteries (arteries), so if there is a slow narrowing of the main artery, the smaller arteries (so-called collateral) reach to grow, and to some extent over hovedarteriens function. The collateral arteries of the heart is very small and inadequate. A narrowing of an artery in the heart is often more serious nature than in other tissues.

Symptoms of calcification of the coronary arteries

Many people living with arteriosclerosis of the coronary arteries pulse without knowing it. One can see that nothing of the problem until around. 2 / 3 of the diameter of a blood vessel is blocked.

The first symptoms will arise in connection with physical or mental strain, the heart needs a lot of oxygen. They narrowed coronary arteries can not supply the required quantity of oxygen, and it turns out the pain. These are called cardiac pain or angina cramp.

The pain felt murrende and sultry behind the sternum (it feels as if the chest is laced together). The pains can jet off to the shoulders, arms, neck, jaw, back or abdominal region. Often, the radiation left side of the body.

If the symptoms occur at rest (eg. At night), it is a sign of severe narrowing of the coronary artery.

Beyond the pain may occur:

  • Shortness of breath.

  • Palpitations.

  • Sweat Tours.

  • Dizziness.

  • Malaise.

The first time Monday experiencing heart spasm, it can be very angstfremkaldende.

Closeable artery completely arises death of heart muscle. It is called acute myocardial infarction (AMI) or myocardial infarction and sudden show of strong pain in the same area as at the heart spasm.

Other symptoms that may manifest itself as a myocardial infarction:

  • There may be simultaneous symptoms of heart failure, especially in the elderly.

  • Accompanying vomiting and nausea.

  • The sickness is pale and obnoxious sweating.

  • Intense fear.

  • Dizziness and fainting.

  • Rapid breathing.

Precautions and diagnosis

In all ages, and especially if you are experiencing incipient signs of arteriosclerosis, it is important wherever possible to avoid the above-mentioned triggers.

If you are not hereditary congested, there is very little risk from contracting the disease arteriosclerosis, if you are of normal weight, grows exercise, avoid stress and not smoking. Monday suffering from heart seizures, it is especially important to change his lifestyle on the points which are possible.
Have we diabetes (diabetes), it is important to pay extra attention to their blood pressure (see High blood pressure) and on signs of arteriosclerosis.

Has it been reported angina, it is very important that you follow this advice with regard to medication and physical exercise. It does not mean that we should refrain from physical activity (including sexual activity). You can indeed move the border to attack, so they come less often if you regularly cultivate easy exercise such as cycling and walking.

Read more in "Atherosclerosis - prevention."

We must at all times follow the treatment and the guidelines as one's doctor prescribes.

Diagnosis can be made on a coronary angiography (CAG). However, this is a somewhat rigorous examination of the patient, and therefore often carried out in connection with ballonudvidende treatment. For diagnosis of coronary disease and heart spasm see them.

Treatment of kranspulsåreforsnævring

Initially, your doctor will instruct in a healthier lifestyle by stopping smoking, change of diet (more green and more fiber diet), increased exercise and relaxation.

Simultaneously treated for a high cholesterol with cholesterol-lowering medication (statins).

Possibly high blood pressure are also addressed.

If you are plagued by heart spasms, you must rest by signs of attack and always have nitroglycerin tablets are to be melted under the tongue at the attack.

In more severe cases of heart spasm will be offered Monday ballonudvidelse operation with the narrowed artery. It is often inserted in the same context, a grill (a stent), which keeps åren constantly open.

Is ballonudvidelse not possible, you can choose a by-pass operation, where you keep an artery from the chest down to the coronary artery after forsnævringspunktet to return blood to the heart. Another solution is to take a piece of blood vessel (vein) from the leg and sew it on coronary artery before and after throat, so the blood runs out of (town-match) throat.

Treatment of acute myocardial infarction must be done and is a specialist task, see more of this disease.

Select and complications

Sheep arteriosclerosis allowed to develop, will cause the above complications, heart spasm and myocardial infarction, and ultimately leads to the death.

New medical treatments and changing lifestyles, however, have significantly extended the life of people with arteriosclerosis in
