There was invented a special abbreviation: FACES. F means fatigue. If the heart doesn`t pump enough quantity of blood with oxygen, to fill the whole organism with energy, a person feels tired. A stands for activity limitation. People knowing everything about the heart failure can`t fulfill their usual tasks as they get tired very quickly and have dyspnea. C means congestion. Liquid accumulation in the lungs provokes croaking, coughing and shortness of breath. E is Edema (when ankles swell).
