Shortness of Breath
There is a link between the operation of your heart and breathing. In general, the heart is responsible for pumping blood, which provides nutrients and gets oxygen from the lungs. When you have a heart attack, this function is affected. As a result, your lungs lack blood to work as usual and lead to shortness of breath. In women, this symptom can be followed by unusual fatigue. The feeling can be described as if you have been exercising heavily even when you only relax and sit all the time. Do not take this sign lightly because it might indicate other serious problems. [3]
