The health of your heart and cardiovascular system is an extremely important thing to keep your eye on. As heart disease is the number one cause of death in North America, your life literally depends on your ability to monitor and correctly interpret the early signs of heart trouble.

According to MedicineNet, this can be a sub-symptom of dyspnea.
