"5 shocking signs your heart is in the 'RED ZONE'"

The "5 shocking signs your heart is in the 'RED ZONE'" typically refer to critical symptoms indicating potential heart issues. Based on the search results, these signs include:

1. **Fatigue**: Unexplained, persistent fatigue can signal heart failure or coronary artery disease, especially if it’s new and constant[2][3].

2. **Shortness of Breath**: Experiencing shortness of breath during minimal activity or at rest may indicate heart problems, as it can signify that the heart isn't pumping effectively[2][3][4].

3. **Swelling in Legs or Ankles**: Edema, or swelling in the lower extremities, can be a sign of heart failure, as it indicates fluid buildup due to poor circulation[2][3][5].

4. **Chest Pain or Discomfort**: While not always present, chest pain can be a classic symptom of heart issues. Discomfort may also radiate to the arms, back, neck, or jaw[4][5][6].

5. **Heart Palpitations**: Irregular or rapid heartbeats can indicate underlying heart conditions, particularly if they occur at rest or are accompanied by other symptoms[2][3][4].

Recognizing these signs early is crucial for timely medical intervention.
