Your heart can sometimes show warning signs before a serious problem occurs, but many heart conditions develop silently, and a single symptom does not always mean your heart is in danger. Still, these signs should be taken seriously—especially if they are new, severe, or worsening.
5 possible warning signs of a serious heart problem
- Chest pressure, squeezing, or pain
- A feeling of heaviness, tightness, burning, or pressure in the chest can be a sign of reduced blood flow to the heart.
- Pain may spread to the left arm, shoulder, jaw, neck, or back.
- Shortness of breath
- Trouble breathing during activity or even at rest can be a sign that the heart is struggling to pump effectively.
- Unusual fatigue or weakness
- Extreme tiredness that is new or unexplained—especially with other symptoms—can sometimes signal heart problems.
- Dizziness, fainting, or irregular heartbeat sensations
- Feeling like your heart is racing, skipping beats, or causing lightheadedness may indicate a rhythm problem or another heart issue.
- Swelling in the legs, ankles, or feet
- Fluid buildup can occur when the heart is not pumping efficiently.
Seek emergency help immediately if you have:
- Chest pressure or pain lasting more than a few minutes
- Chest discomfort with sweating, nausea, severe weakness, or shortness of breath
- Sudden fainting
- Sudden weakness on one side of the body or trouble speaking (possible stroke symptoms)
Reducing heart risk
- Control blood pressure, cholesterol, and blood sugar.
- Avoid smoking and tobacco.
- Stay physically active.
- Eat a heart-healthy diet.
- Keep regular medical appointments, especially if you have risk factors.
If you are asking because you or someone close to you is experiencing symptoms right now, tell me the person’s age, the exact symptoms, when they started, and whether there is chest pain or breathing difficulty.
