What is myocardial infarction?
Myocardial infarction is a formidable combination, able to frighten many. And really, who hasn’t heard stories about that “neighbor had a heart attack”, after which he could not go to work? But this mythical neighbor was lucky, the consequences of the disease could be much more serious… however, ask many of us what the hell is this stuff – infarction, and not all will respond. Will ask a specialist.
What is the myocardium?
The myocardium is the muscle of which is almost all heart . Due to this structure, it is able to undertake the enormous job of pumping and maintenance of all organs and tissues with blood, filled with oxygen, nutrients and other essential for life substances.
Heart beats about 100 thousand times a day with a force sufficient to “push” blood through the veins, capillaries, arteries, total length of more than 100 thousand miles… For a day heart of an adult pumps about 14 tons of blood. And for month, year, decade? It is estimated that over a lifetime (will take 70 years) the heart performs work equivalent to lifting 10 tons of cargo at 16-km altitude. This little worker, the size of which does not exceed the size of a fist, works tirelessly, not stopping even at neskolkikh…
And we’re getting to it. For such a large work, the heart itself needs a better diet. And although its mass is 200 times smaller than the body, barely a tenth of the whole blood.
To deliver this significant amount of blood nature has surrounded the heart of a rich network of blood vessels of the heart, which resembles a crown. Hence the name: Coro nary artery .
Cardiac vessels such elastic tubes. With the hard work they expand and increase the blood flow to the heart . Now imagine the following. One of the heart vessels are narrowed or have become impassable. This can sometimes be the result of a sudden constriction or obstruction of its blood clot, called a thrombus. Contribute to the formation of deposits in the vascular wall of elements body fat, which will eventually become dense and begin to narrow or close the lumen of the vessel (the process of deposition and compaction in the vascular wall of the fat particles is called atherosclerosis).
The area of the myocardium in the area of the modified vessel is not receiving blood at all, or gets her a little. As a result, in this area may develop a shortage of blood — anemia, ischemia (from the Greek words “Isho” hold back, “EMA” — blood), and starvation due to the shortage or absence of nutrients and oxygen. CERD TSE reports this pain. If this condition and therefore, heart pain continues for two to three hours (sometimes even a little more than half an hour), in a starving land develop changes which prevent its ability to contract. These changes are called heart attack . Because they occur in the myocardium . and the current economic condition, or illness, referred to as ” myocardial infarction “.
Who most often suffers from myocardial infarction?
This is a serious illness. The risk is especially high in men older than 35 years. However, in recent years noticeable rejuvenation of a heart attack . For example, we observed in the clinic fifteen-year-old boy who suffered severe macrofocal myocardial infarction. He still was lucky, but many with this diagnosis die. And mainly because time does not call for an ambulance, hoping that the pain arose in the heart, “let go” and get…
How to evaluate the seriousness of the situation, to understand what starts a heart attack? What are the typical symptoms of myocardial infarction, signs of its approach?
Myocardial infarction often warns of its approach, “knocking at the door”. It is important to hear this knock. Four out of five caught they can be more or less long period of Pis, which is most often expressed by the so-called unstable angina .
What is unstable angina what are the signs and symptoms ?
Here is a simple everyday example. If a person is walking at your usual pace on the usual route, say to work or from work, forced to stop due to squeezing pain or burning sensation behind the breastbone, and this continues for years, it suffers from stable angina . it is possible to live a long time.
But when such attacks became more frequent, the man every day is getting worse, we’re talking about unstable angina . This is a warning, a signal that people have to rush to the hospital, to strengthen the treatment, try to prevent a heart attack . And when myocardial infarction happens, then, first of all, it may be due to the taken measures, less severe, and secondly, in any case, the patient in the most risky period, will be surrounded by doctors and will receive the maximum help. So, the faster the patient will go to the doctor, so he has more chances of a favorable outcome.
Clinical examination helps early detection and treatment of diseases. So, during the last survey more than thirteen percent of the men we have identified above and economic heart disease . Almost a quarter of them did not even know existed! It was enough the first examination, and the disease was discovered. That’s the kind of efficiency of prophylactic medical examination!
In addition, such periodic studies provide the opportunity for individual health promotion, health education. If the survey reveals people are not equal in the severity of the disease, with varying degrees of risk. Now, different groups and can be explained in different ways, how to behave in a particular situation: at that respond, in any case, just to be cautious, to take certain measures, and in what way without delay, consult doctor. It can be crucial to the outcome of the disease, will help to avoid tragic surprises…
So, you begin with General surveys and gradually emit the most endangered group of patients?
You are absolutely right. I think this principle of gradual selection of the most dangerous patients — right in the prevention of cardiovascular diseases, including myocardial infarction . In the hospital you meet every day with your doctor at any time of the day can get, if the need arises, assistance from medical personnel and necessary medicines.
