Myocardial infarction is a relatively common critical illness in our daily lives. Many patients often delay their condition severely due to untimely treatment, which becomes an important cause of disability and death. So how should myocardial infarction be treated? It should be treated from the following two aspects: First, acute myocardial infarction. For acute myocardial infarction, it is necessary to promptly open the occluded blood vessels, restore cardiac perfusion, and save viable myocardium. This can be achieved through emergency interventional treatment or thrombolytic therapy. Second, old myocardial infarction. At this time, treatment mainly involves taking oral aspirin and statins to stabilize the disease and prevent the condition from worsening or deteriorating. (Medication should be used under the guidance of a professional doctor.)

Causes of Myocardial Infarction

Myocardial infarction is a relatively common severe heart disease in clinical practice, which can lead to serious complications and even death if effective emergency treatment is not administered. The main cause of myocardial infarction is due to long-term dyslipidemia. Elevated blood lipids cause arteriosclerosis and coronary artery hardening, thickening of the intima, and plaque formation. High lipids slow down blood flow, making it very easy for blood clots to form. Detached plaques and the formation of blood clots obstruct the blood vessels supplying the heart muscle, causing the heart muscle to lose its blood supply and undergo necrosis.

Heart attack tests

Patients with myocardial infarction require the following comprehensive assessments: 1. Electrocardiogram (ECG). An ECG is an essential test that can reveal specific changes associated with myocardial infarction. 2. Cardiac echocardiography. This imaging test can reflect the activity of the ventricular walls and cardiac function. 3. Laboratory tests, such as complete blood count (CBC). A CBC can show increases in total white blood cell count and C-reactive protein, along with tests for cardiac biomarkers. These cardiac biomarkers help to determine the extent of myocardial infarction. 4. Coronary angiography. Coronary angiography is the gold standard for diagnosing coronary heart disease. Patients with myocardial infarction need an urgent evaluation to determine the degree of narrowing in the coronary arteries, and if necessary, stent placement treatment should be considered.

The difference between myocardial infarction and myocardial infarction

Myocardial infarction and myocardial necrosis have no significant difference; both are caused by the blockage of coronary arteries leading to ischemic necrosis of the heart muscle. The mechanism of onset and the pathologic changes are the same. In the event of a myocardial infarction, immediate resuscitation treatment is necessary. Without timely treatment, the infarcted area may increase and complications can occur. Common complications include heart failure, arrhythmias, and cardiogenic shock, which can be severe enough to cause death. In the case of a myocardial infarction, it is essential to administer effective medications under the guidance of a doctor to reduce the infarcted area and minimize complications.

Manifestations of the ST segment in myocardial infarction

Acute myocardial infarction is divided into three stages: the hyperacute phase, the acute phase, and the recovery phase. The hyperacute phase generally occurs within half an hour of the cardiac vessel blockage. During this time, the myocardium has not completely necrosed, but there can be high, pointed T-waves on the electrocardiogram (ECG), and the ST segment remains unchanged. This stage is prone to misdiagnosis. In the acute phase, which lasts for more than 30 minutes, the ST segment elevation begins to appear on the ECGs of most people. Most of these elevations are horizontal or saddleback, although slanting elevations are less common. During the recovery phase, the ST segment on the ECG gradually returns to normal, and later, T-wave changes occur. Some individuals may develop ventricular aneurysms, which might prevent the ST segment from returning completely to baseline.
