Dr. Tian Hongbo
Precursors of myocardial infarction include chest pain or discomfort, nausea and vomiting, shortness of breath, sweating and dizziness, fatigue, and weakness.
1. Chest pain or discomfort:表现为 severe chest pain or a feeling of pressure, which may extend upward to the jaw, neck, back, or left arm, or cause discomfort in the stomach or abdominal area.
2. Nausea and vomiting: Before a heart attack, one may feel nauseous and experience vomiting. These symptoms might occur along with chest pain or appear independently.
3. Shortness of breath: Due to reduced cardiac function, the body requires more oxygen, causing breathing to become rapid or difficult. This is an important precursor of myocardial infarction and requires immediate attention.
4. Sweating and dizziness: Before a heart attack, patients may suddenly sweat profusely and feel dizzy. This occurs due to reduced blood flow, causing adverse bodily reactions.
5. Fatigue and weakness: If the myocardium is continuously damaged, individuals may feel fatigued, weak, or even lose consciousness. This feeling of fatigue may become more noticeable during daily activities, such as walking or climbing stairs.
If these symptoms occur, immediate medical evaluation and treatment should be sought to prevent deterioration of the condition.
