What are the warning signs of acute myocardial infarction?

Acute myocardial infarction usually refers to acute heart attack, a cardiac condition caused by myocardial necrosis due to prolonged ischemia. Common warning signs of this disease include chest pain, dizziness, nausea, excessive sweating, and shortness of breath.

1. Chest Pain

Acute and persistent ischemia in the coronary arteries leads to massive death of myocardial cells and insufficient blood supply to the heart, resulting in significant chest pain. The pain is often described as sharp or stabbing, like being pricked by a needle or cut by a knife.

2. Dizziness

Acute myocardial infarction reduces the heart's pumping function, leading to inadequate oxygen delivery throughout the body, which may cause symptoms such as dizziness and headache.

3. Nausea

This is also a common sign of acute myocardial infarction. It primarily results from insufficient blood flow to the digestive system, causing abnormal intestinal motility and irregular gastric acid secretion.

4. Excessive Sweating

In the early phase of an acute myocardial infarction, prominent symptoms such as severe chest pain and a feeling of suffocation often occur, causing significant physical discomfort that triggers sweating. Additionally, dysfunction of the sympathetic and parasympathetic nervous systems may lead to overactivity of the sympathetic nervous system, further increasing perspiration.

5. Shortness of Breath

Shortness of breath is a common symptom preceding acute myocardial infarction. It mainly occurs because myocardial ischemia increases the workload on the heart, causing an elevated heart rate.

Acute myocardial infarction significantly impacts the body and can threaten life in severe cases. Therefore, if any early warning signs appear, prompt medical evaluation and treatment are essential.
