Know the signs01
What are the signs of a heart attack?
Most people feel discomfort in the center of the chest that lasts or comes and goes: pressure, squeezing, fullness or pain 1.
- Chest discomfortPressure, squeezing, fullness or pain in the center of the chest, lasting more than a few minutes or coming and going.
- Discomfort elsewhereArms, back, neck, jaw or stomach.
- Other signsShortness of breath, cold sweat, nausea or lightheadedness.
- Stroke: B.E. F.A.S.T.Balance, Eyes, Face, Arms, Speech, Time: any sign means call 911 and note when it started.
- Call 911, do not driveAny of these: call 911 right away. Do not drive yourself or the person to the hospital.
Signs from AHA 1 and CDC 2. This list is not complete, and a supplement is never a reason to wait.
Other signs can show up with the chest feeling or on their own. Do not wait for a clear picture. If you are unsure, the advice is the same: call 911 1.
Where it shows02
Where else can a heart attack be felt?
Beyond the chest, the discomfort can sit in the arms, back, neck, jaw or stomach 1.
| Sign | How it may feel |
|---|---|
| Chest | Pressure, squeezing, fullness or pain, constant or on and off |
| Upper body | Discomfort in the arms, back, neck, jaw or stomach |
| Breathing | Shortness of breath, with or without chest discomfort |
| Other | Cold sweat, nausea, lightheadedness |
Not every attack looks like a film scene. Some are mild at first. Trust the pattern, not the intensity.

Can Melonex help in a heart attack?
No. Melonex is a dietary supplement, and no supplement is an emergency treatment.
The front reads "Heart Support*", and the star leads to the FDA statement that the product is not meant to diagnose, treat, cure or prevent any disease. One of its names, arginine, was studied in 153 people after a first heart attack. It did not change ejection fraction or vascular stiffness. Six people in the arginine group died against none on placebo, and the safety committee closed enrollment 3. A patient guide adds that arginine is not recommended after a recent heart attack 4.
Ask your cardiology team before you take any supplement. Keep taking your prescribed medicine 5.
