Feeling lightheaded and losing consciousness is very common among heart patients. When the heart is not pumping blood well it is because the blood flow is blocked from a clogged artery or the narrowing of a valve. If you ever feel shortness of breath and you faint for a short period of time, call a doctor immediately and have your heart checked.

9. Your skin becomes paler or takes on a bluish color

This is not one of the most common symptoms, but when it appears, it’s due to reduced blood flow, a decreased number of red blood cells, and can be a sign that your heart doesn’t pump blood the way it should. Shock is the main reason for this symptom and the paleness can appear in your entire body or in a certain body part, for example a limb. However, if you notice paleness do not panic. Check out whether you are suffering from shock or there is some other issue like anemia.
