Heart failure occurs when something damages the heart muscle or reduces the heart's ability to pump effectively
The failing heart will not be able to pump well enough to keep up with the body's demand for oxygen-rich blood. Here are 5 early telltale signs of a heart failure that one must know
Fatigue: When the heart can't pump enough oxygen-rich blood, a general feeling of tiredness or fatigue sets in
Activity limitation: People with heart failure are often unable to do their normal activities
Congestion: Fluid buildup in the lungs can result in coughing, wheezing, and breathing difficulty
Edema or ankle swelling: Fluid can collect in the ankles, legs, thighs, and abdomen
Shortness of breath: Fluid in the lungs makes it difficult for carbon dioxide in used blood to be exchanged for fresh oxygen
