#1 – Shortness of Breath
One of the most common signs of heart disease is shortness of breath. Normally, most people experience shortness of breath after an intense workout or climbing the stairs. However, going out of breath while relaxing on a sofa, for example, is a very bad sign that shouldn’t be ignored.
If this happens, it means that the heart is unable to pump blood out effectively, causing the lungs to congest due to leaking fluid, and this leads to difficulty with breathing.
