What are common warning signs of a heart attack?
Key Takeaways
- Chest pressure or discomfort lasting more than a few minutes is the most common symptom.
- Pain may radiate to the left shoulder, left arm, neck, jaw, or upper abdomen.
- Atypical symptoms like unexplained shortness of breath, severe fatigue, or indigestion are common in women.
- Troponin-I and High-Sensitivity CRP blood tests assess cardiac muscle damage and inflammation.
- Immediate emergency medical response is mandatory if a heart attack is suspected.
Common heart attack warning signs include persistent central chest heaviness, shortness of breath, cold sweating, nausea, and pain spreading to the neck, arm, or back.
A heart attack (Myocardial Infarction) occurs when blood flow to a section of the heart muscle is severely blocked, usually by a clot in a coronary artery damaged by cholesterol plaque build-up.
### Primary Symptoms of a Heart Attack
1. **Chest Discomfort**: Feeling of fullness, squeezing pressure, or burning in the center of the chest lasting more than a few minutes.
2. **Radiating Pain**: Discomfort spreading to one or both arms, back, neck, jaw, or stomach.
3. **Shortness of Breath**: Occurs with or without chest discomfort.
4. **Cold Sweats & Lightheadedness**: Sudden dizziness or unexplained break out in cold sweat.
### Diagnostic Blood Screening
- **Lipid Profile**: Evaluates LDL, HDL, and Triglycerides to check plaque risk.
- **hs-CRP (High-Sensitivity C-Reactive Protein)**: Measures underlying arterial vascular inflammation.
- **Troponin-I**: Highly sensitive cardiac biomarker released when heart tissue experiences ischemic stress.
