With a heart attack (myocardial infarction), almost everyone had been in touch. Be it as a concerned friend or as an interested party of a heart attack. Missing our cycle engine oxygen, he comes to stutter or stops altogether.
Heart attack due to reduced oxygen supply
The heart muscle needs like any other organ of oxygen for its activity. This is delivered via the blood in the coronary vessels (coronary arteries) are available. If these narrows, the muscle can not pump enough – leading to reduced exercise capacity and heart pain (angina pectoris). Heart attack is almost the maximum expression of the reduced oxygen supply: At one point, the blood supply suddenly so far suspended that it supplied muscle (myocardium) is limited not only in his work, but even get enough oxygen and nutrients and dies – a heart attack , often with sometimes life-threatening consequences. Survived the defendant be heart attack, scar tissue and the infarct remains inoperable.
Forms of heart attack
Depending on which of the halves of the heart is affected by a heart attack, heart attack, we distinguish the left and the right of heart attack. Depending on the affected area in front of a heart attack and myocardial infarction. The right ventricle is only rarely and then usually affected together with the left ventricle during a heart attack, which is related to the course of the three main coronary artery. Subject to necrosis (death) all the layers of tissue in a heart attack, one speaks of a transmural infarction, only the inner layer is damaged by a layer infarction.
Heart attack harbingers
Earlier were more persistent angina pectoris attacks (decrescendo angina) viewed as a harbinger of a heart attack. We now know that it had heart muscle can be destroyed. Therefore, this form is now also attributed to the infarction. In contrast to the classic heart attack show up here but not the typical changes in the ECG – an elevation = elevation of the ST segment. Therefore, this form of heart attack as NSTEMI (non ST-segment elevation myocardial infarction) refers, however, the classic heart attack as STEMI (ST-segment elevation myocardial infarction). The generic term for both forms of the acute coronary syndrome.
