1. You feel queasy
That annoying feeling in your stomach could be more, because, when your stomach is tied up in knots suddenly, you should visit a doctor as soon as possible. Also, you can experience vomiting out of nowhere. These signs are warnings of a heart attack, so you better get them treated early. Don’t play with your life!
2. Breathing problems
If you’re struggling to breathe and you don’t not exactly the cause, this could be a sign that your heart isn’t working as it should be. Those who have heart disease are likely to develop pulmonary edema, meaning that their lungs fill with fluid. So, when your heart doesn’t carry blood properly, your blood pressure increases and that’s causing the transfer of fluid from your blood vessels to the alveoli. You can often feel a heaviness in the chest, if you have heart problems.
