Acute myocardial infarction is a relatively common phenomenon, which often occurs in the early morning and is more common during quiet times. Acute myocardial infarction can present with some adverse symptoms, and patients should seek timely and targeted treatment. It is important for patients to avoid staying up late, as this can have significant harmful effects on the human body, especially on the heart. Regular exercise and avoiding excessive fatigue are also recommended. Now let's take a look at the most prominent symptoms of acute myocardial infarction.

1. Most Prominent Symptoms of Acute Myocardial Infarction

The most prominent symptom of acute myocardial infarction is pain, which is also the first to appear and most often occurs in the early morning. The location and nature of the pain are similar to angina pectoris, but the triggers are often not obvious, and it often occurs during quiet times. The pain is severe, lasts for a long time, and can last for several hours or even longer.

2. Common Symptoms

About half or more of patients with acute myocardial infarction experience prodromal symptoms 1-2 days or 1-2 weeks before the onset of the disease. The most common prodromal symptoms include worsening of previously existing angina pectoris, prolongation of attack duration, or reduced response to nitroglycerin. In some patients who have never had angina pectoris, long-lasting angina pectoris may suddenly appear. The typical symptoms of myocardial infarction include sudden onset of severe and persistent crushing pain in the retrosternal or precordial region, which cannot be relieved by rest or administration of nitroglycerin. It is often accompanied by agitation, sweating, fear, or a sense of impending death. Cardiac arrhythmias are seen in 75% to 95% of patients and often occur within 1 to 2 weeks after the onset of the disease, especially within 24 hours. Anterior wall myocardial infarction is prone to ventricular arrhythmias, while inferior wall myocardial infarction is prone to bradycardia and atrioventricular block.

3. Treatment Guidelines

Acute myocardial infarction is a sudden onset disease that requires early detection, early treatment, and enhanced pre-hospital management. The treatment principles aim to salvage dying myocardial tissue, reduce the infarct size, protect heart function, and promptly manage any complications.
