Heart problems don’t always begin with sudden, severe chest pain. Some warning signs can appear earlier and should not be ignored.
1. Chest Pressure or Pain
A feeling of pressure, squeezing, heaviness, or discomfort in the chest can be a warning sign of a heart attack—especially if it lasts several minutes or comes and goes.
2. Shortness of Breath
Unexplained breathlessness, particularly during normal activities or at rest, can sometimes indicate a heart problem.
3. Pain Spreading to the Arm, Jaw, Back, or Shoulder
Heart-related discomfort may spread beyond the chest and affect the arm, shoulder, back, neck, or jaw.
4. Unusual Sweating
Sudden cold or unexplained sweating, particularly when combined with chest discomfort, nausea, or weakness, can be a warning sign.
5. Dizziness or Fainting
Unexpected dizziness, lightheadedness, or fainting can sometimes occur when the heart is not pumping effectively or when there is an abnormal heart rhythm.
6. Unusual Fatigue
Extreme or unexplained tiredness—especially when it is new or occurs with other symptoms—can sometimes be associated with heart disease.
7. Fast, Fluttering, or Irregular Heartbeat
A racing, pounding, or irregular heartbeat that keeps happening may indicate an abnormal heart rhythm and should be medically evaluated.
When Is It an Emergency?
Do not wait for symptoms to disappear if you have chest pressure or pain, severe shortness of breath, fainting, or discomfort spreading to your arm, back, neck, or jaw.
Seek emergency medical care immediately, particularly when symptoms are sudden, severe, or accompanied by sweating, nausea, or weakness.
The Bottom Line
Recognizing warning signs early can be important, but these symptoms can have many causes. A healthcare professional can determine whether they are related to your heart and recommend appropriate testing.
