What are the main symptoms of myocardial ischemia?

Myocardial ischemia is a decrease in blood perfusion to the heart, resulting in reduced oxygen supply. Symptoms include chest pain or discomfort, breathing difficulties, palpitations or irregular heartbeat, fatigue or weakness. Treatment methods include lifestyle changes, medication, intervention, and surgery. Myocardial ischemia is a pathological condition in which the blood perfusion of the heart is reduced, resulting in reduced oxygen supply to the heart, abnormal myocardial energy metabolism, and inability to support normal heart work. The main symptoms of myocardial ischemia include: 1. Chest pain or discomfort: This is the most common symptom of myocardial ischemia, usually manifested as chest pressure, tightness, burning or pain, can radiate to the left shoulder, left arm, neck or jaw, duration is generally a few minutes, rest or sublingual nitroglycerin can alleviate. 2. Dyspnea: Myocardial ischemia can lead to decreased myocardial contractility, reduced cardiac ejection, pulmonary congestion, resulting in breathing difficulties. Patients may feel shortness of breath, wheezing or breathlessness. 3. Palpitations or irregular heartbeat: Myocardial ischemia can affect the normal rhythm of the heart, resulting in palpitations or irregular heartbeat. Patients may feel too fast, too slow or irregular heartbeat. 4. Fatigue or weakness: Myocardial ischemia can lead to decreased heart function, systemic blood supply deficiency, patients may feel fatigue, weakness, weakness or fainting. 5. Other symptoms: Myocardial ischemia may also cause nausea, vomiting, dizziness, headache, upper abdominal pain and other discomfort. For the treatment of myocardial ischemia, mainly include the following aspects: 1. Lifestyle changes: A healthy lifestyle is important for the treatment of myocardial ischemia. It includes smoking cessation, alcohol restriction, weight control, moderate exercise, and a low-salt, low-fat diet. 2. Medication: Your doctor may prescribe antiplatelet drugs, statins, nitrates, beta blockers, etc. to improve myocardial ischemia and prevent complications. 3. Interventional therapy: For patients with severe myocardial ischemia or refractory to medical therapy, intervention such as percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) may be necessary.4.Surgical treatment: In some cases, such as myocardial infarction complicated by ventricular septal perforation or papillary muscle rupture, surgical treatment may be required. Myocardial ischemia is a serious disease. If the above symptoms occur, you should seek medical attention in time for relevant examination and treatment. At the same time, for high-risk groups, such as hypertension, hyperlipidemia, diabetes, smoking, etc., regular physical examination should be carried out so as to detect and treat early. In addition, maintaining a healthy lifestyle and actively treating underlying diseases are also important measures to prevent myocardial ischemia.
