2. Unusual or Persistent Fatigue
Feeling tired after a long day is normal, but persistent and unexplained fatigue may sometimes signal heart problems.
Research published in the Circulation Journal and supported by the American Heart Association found that many heart attack patients reported severe fatigue in the weeks leading up to their cardiac event.
You may notice:
Extreme exhaustion after simple activities
Difficulty completing normal daily tasks
Feeling constantly drained or weak
This fatigue can occur because the heart struggles to deliver oxygen-rich blood throughout the body.
3. Shortness of Breath
Another possible early warning sign is difficulty breathing, especially during routine activities.
When the heart cannot pump blood effectively, fluid may build up in the lungs, making breathing more difficult.
Symptoms may include:
Breathlessness while walking or climbing stairs
Waking up suddenly at night struggling to breathe
Feeling unable to take a full breath
Medical professionals refer to this symptom as dyspnea, which is commonly associated with heart disease.
4. Chest Discomfort or Pressure
