Acute myocardial infarction
Atypical symptoms of myocardial infarction
We say myocardial infarction is a serious heart disease. Common symptoms of myocardial infarction include chest pain. However, some patients with myocardial infarction do not present with chest pain but exhibit other atypical symptoms. For example, some patients present with severe chest tightness and shortness of breath, or acute left heart failure. Others may seek treatment for palpitations or slow heart rate and other arrhythmias. Some exhibit symptoms like toothache or upper abdominal pain, while others may experience dizziness. There are also patients who present with low blood pressure or even go into shock. Therefore, for these patients, it is crucial to perform timely tests like electrocardiograms and troponin levels, and have a specialist make a diagnosis to avoid delays in treatment.
How long does the pain from a myocardial infarction last?
Acute myocardial infarction often develops from angina pectoris. When angina persists for more than 30 minutes, myocardial necrosis begins. After the myocardial necrosis, symptoms similar to those of a burn appear, such as reddening of the myocardium, blistering, and necrosis. Generally speaking, these symptoms last no less than three days. Many people experience significant improvement after three days because the area of myocardial infarction is relatively small. In patients with extensive myocardial infarction, symptoms can last for 7 days or even longer. During this time, patients may also experience respiratory difficulties, recurrent chest pain, and even sudden death. Therefore, the duration of symptoms in myocardial infarction generally ranges from 3 to 7 days. If there is no improvement within this period, the disease might have led to severe complications.
Is vomiting severe in myocardial infarction?
Patients with myocardial infarction often have a history of hypertension, coronary heart disease, and diabetes. They usually experience repeated episodes of angina. After angina, the chest pain persists and cannot be alleviated, often including feelings of chest oppression and pressure. Some patients may also experience nausea, vomiting, and fainting, but most do not have severe vomiting. Some patients, because of inferior wall myocardial infarction or posterior wall myocardial infarction, may develop right ventricular dysfunction, or during the treatment process, due to decreased appetite, may suffer from severe vomiting caused by low potassium and low sodium levels. However, this can generally be corrected through treatment.
Symptoms and warning signs of myocardial infarction
Patients with myocardial infarction often have some precursor symptoms before the onset of a heart attack, including chest tightness, palpitations, irritability, fatigue, and episodes of angina, among which the angina episodes are most characteristic. This angina can manifest as the first occurrence of angina, or as a worsening of previously experienced angina symptoms. It is characterized by more intense chest pain, longer duration, and often occurs without clear triggers. Nitroglycerin taken sublingually does not fully relieve it. These symptoms should be taken seriously, and it is important to promptly visit the cardiology department of a hospital. Through inpatient treatment, the condition can be stabilized, and many patients can avoid an acute myocardial infarction.
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.
Symptoms of myocardial infarction
Myocardial infarction is a relatively common disease in daily life, and it also poses a serious threat to people's health and safety. The symptoms of a myocardial infarction mainly include the following aspects: First, severe chest pain, which is often the most common symptom of myocardial infarction, typically feels like a crushing sensation or is accompanied by a feeling of impending doom. Second, symptoms of heart failure, which, when myocardial infarction is complicated by heart failure, often manifest as difficulty breathing and profuse sweating. Third, symptoms of arrhythmia, which, when myocardial infarction is complicated by arrhythmia, often presents with symptoms like palpitations and dizziness.
The difference between acute myocardial infarction and myocardial infarction.
Acute myocardial infarction, characterized by sudden onset, involves persistent angina, profuse sweating, a sense of impending doom, difficulty breathing, and chest tightness. Myocardial infarction, also known as heart attack, refers actually to the same condition and there is no difference between them. Once a myocardial infarction occurs, the patient should immediately go to the hospital for medical attention. Diagnostic tests such as an electrocardiogram, cardiac ultrasound, coronary CT, and coronary angiography should be conducted. These tests help determine the extent, severity, and location of the infarction, understand the degree of narrowing of the vessel, and develop a treatment plan to save the patient's life.
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 is what disease
Myocardial infarction is a serious heart condition caused by the formation of atherosclerotic thrombosis in the coronary arteries, blocking the blood vessels that supply the heart muscle and leading to myocardial necrosis. Timely rescue treatment is necessary, and without effective treatment, it can lead to serious complications. Common complications include heart failure, cardiogenic shock, and arrhythmias, which can be life-threatening. Therefore, after a myocardial infarction occurs, it is essential to immediately go to the hospital for rescue treatment, using effective medications to promote blood circulation, remove blood stasis, dilate the coronary arteries, and improve myocardial blood supply, among other treatment methods.
How to treat atrial myocardial infarction?
Atrial myocardial infarction is also a type of myocardial infarction. Isolated atrial myocardial infarction is relatively rare and often coexists with ventricular infarction. Therefore, the treatment principles for myocardial infarction are essentially the same, focusing on promptly improving myocardial ischemia, myocardial necrosis, and the long-term prognosis of the patient. The treatment mainly includes: first, reperfusion therapy, which involves thrombolysis for ST-segment elevation cases, stent placement for most patients, and bypass surgery for a small number of patients. The second aspect is secondary prevention and treatment, including antiplatelet therapy, blood pressure control, blood sugar management, diet, exercise, and other comprehensive treatments. The peculiarity of atrial myocardial infarction is that some patients may experience atrial fibrillation, thus some of these patients may require treatment to control ventricular rate.
