11 Signs You Are About To Have a Heart Attack

2.Shortness of Breath

The heart and the lungs are closely connected. The heart pumps blood to the lungs to get oxygenated. This oxygenated blood is transferred back to the heart for distribution to other organs in the body.

If your heart fails to pump blood well to the lungs and other organs, then you are likely to experience shortness of breath as a result of not having enough oxygen in the blood and poor circulation.

This symptom usually manifests when you engage in physical activity such as walking, running, or going up the stress.
