Ischemia and myocardial infarction
Myocardial infarction is a consequence of ischemic heart disease. The frequency of occurrence, complications, disability ischaemia is in the first place. Cause ischemia the following – there is a narrowing of the vessel that feeds some portion of the heart muscle. People allow increased load or has a different reason for highly elevated blood pressure, and a certain portion of the heart muscle suffers. Simply put, he dies – a heart attack develops. In that moment, when this portion of the heart muscle does not receive blood (especially blood and oxygen), develops pain attack, which is very characteristic. The pain in this case indicates preinfarction condition.
The symptoms of a preinfarction state
Pain when ischemia occurs, as a rule, not in the heart. This chest pain. Patients often describe it as feeling like hammered count. it's hard to breathe, man cannot move, he has a fear of death. A characteristic symptom in people who have this attack is repeated, takes nitroglycerin. The pain goes away. If the person at the time the pain moves, he is forced to stop and the pain stops. So it is not the pain itself, and the whole dynamic of pain (during exercise – appears when peace goes away, even without medication) if it is a young man, says that there is a high probability of ischemic heart disease resulting from her heart attack.
According to research, the main risk factors leading to coronary heart disease — Smoking, high blood pressure (hypertension) and high cholesterol content in plasma (hypercholesterolemia).
Manifestations of ischemic heart disease arise from narrowing of the coronary arteries, which occurs as a result of atherosclerosis. The occurrence of coronary atherosclerosis is affected by heredity, excessive fat intake, constant high blood pressure, Smoking and increased physical activity.
Heart attacks and strokes – two of the most "popular" areas of diseases of the cardiovascular system, life-threatening. To be quiet for the heart, you need to pass the clinical examination.
Today it is precisely known that sports is the main "trump card" in the prevention of heart attacks. Therefore, even if you are already older and not at all a sporty person, worth talking to your doctor, start to play sports.
Advice 2 : How to identify a heart attack
Myocardial infarction is the most serious complication of ischemic heart disease, because this disease can occur circulatory disorders quite large areas of the heart muscle, which can cause significant hemodynamic instability, incompatible with life.
The main symptom that allows to suspect a myocardial infarction, is becoming the attack of pain, which is not like the pain attacks before. The character of the pain may vary in different patients depending on the size of the lesion of the cardiac muscle, but the pain is much stronger than the pain of the next stroke, and is not influenced by any of those medicines, which were effective previously and used for the prevention and treatment of chest pain.
To determine the myocardial infarction and helps unusually long duration of the attack that lasts more than 5-10 minutes, whereas the pain of the next stroke are usually at this time passes, especially when using drugs to treat that contain nitroglycerin. The use of sedatives or other such drugs based on extracts of medicinal plants and sedative means, effective only when the attack of palpitations, but totally ineffective in evolving myocardial infarction. The purpose of these drugs only helps to reassure the patient that affects his subjective state, but it is absolutely not affect the size of the zone of cell necrosis in myocardial infarction.
The development of necrosis provokes the shutdown of a portion of the heart muscle from pumping blood, which can lead to development of stagnation in the big and small circle of blood circulation. Stagnation in the small circle manifested severe dyspnea, which can join cough, indicating possible development of cardiac asthma. Stagnation in the big circle manifested severe fluctuations in systemic arterial pressure. It is accompanied by the development of pronounced hemodynamic disturbances in the organs and tissues of the body. With significant areas of necrosis may cause separation of the heart muscle (a heart), which leads to an almost instant death due to the development of tamponade, the pericardium, where the heart can't decline. Thus, there is an acute attack of cardiac pain almost immediately after which the patient loses consciousness.
Advice 3 : What distinguishes a heart attack from a stroke
Heart attack and stroke – a serious illness, after which it is difficult to return to normal life. Despite the fact that these States are very similar in nature, there are a number of fundamental differences that do not allow them to be confused.
What is a heart attack?
This condition is a partial or total organ damage, which is a consequence of the overlap of a blood clot a major artery. This may be due to a sharp spasm or poor patency of blood vessels, scored cholesteric plaques. Thus, the surrounding tissue gets enough oxygen and nutrients, which have to do with blood. So is the death of the body. Most often occurs in myocardial infarction (cardiac muscle) and brain, rarely of the intestine and kidney. The main cause of blood clots in the arteries – atherosclerosis of the blood vessels.
What are the characteristics of a stroke?
This disease is an acute blood supply disturbance of the brain, which is accompanied by damage of the brain tissue with the violation or complete absence of its functions. Normally the stroke occurs on the background of atherosclerosis, hypertension, diabetes, infectious diseases, stress and excessive exercise. The precursors of the disease are weakness and violation of the sensitivity of individual body parts, as well as poor working memory, language and consciousness.
The longer poor blood circulation in the affected parts of the brain during the stroke, the more functions are lost, perhaps forever.
What is the difference between a heart attack and stroke?
A heart attack is different in that it is a complete or partial tissue death which is the consequence of impaired supply (ischemia) of any organ. Stroke - acute impairment of cerebral circulation, accompanied by tissue damage. A stroke, unlike a heart attack, is a broader concept that includes the rupture of blood vessels, hemorrhage, and other conditions, leading to damage meninges. A heart attack, in fact, is one of the varieties of stroke.
At the same time the onset of myocardial infarction and stroke cerebral vessels can lead to death or coma.
A stroke can be a consequence of myocardial infarction?
Of course, maybe because the main cause of these two diseases – atherosclerosis. In addition, when acute myocardial infarction is often observed heart failure, which may trigger the development of stroke. Another complication of myocardial infarction – thromboangiitis in which a blood clot leaves the heart and blood flow often enters the blood vessels of the brain.
