If you’re referring to a health-awareness headline, the key point is that heart disease can develop without obvious symptoms, so these signs should be taken seriously—but none of them alone proves that your heart is failing.
7 warning signs
- Chest pressure, squeezing, or discomfort
Especially if it occurs with activity, lasts several minutes, or keeps coming back. - Shortness of breath
New breathlessness during ordinary activities or at rest can be a warning sign. - Pain spreading to the arm, shoulder, back, neck, or jaw
This can occur during a heart attack, sometimes with little or no chest pain. - Unexplained sweating, nausea, or vomiting
These can accompany a heart attack and shouldn’t be dismissed when combined with other symptoms. - Fainting or nearly fainting
This can sometimes be related to an abnormal heart rhythm or reduced blood flow. - Swelling of the feet, ankles, or legs
Fluid accumulation can occur with heart failure, although many other conditions can also cause swelling. - A noticeable drop in exercise tolerance
Becoming unusually tired or breathless doing activities that were previously easy can indicate a cardiovascular problem.
🚨 When to get emergency help
Don’t wait if symptoms suggest a heart attack. Persistent or severe chest pressure, severe shortness of breath, fainting, or chest discomfort accompanied by sweating, nausea, or pain spreading to the arm, back, neck, or jaw requires urgent medical attention.
Also, women, older adults, and people with diabetes may experience less typical heart-attack symptoms, so the absence of dramatic chest pain doesn’t necessarily mean the situation is safe.
