Heart failure is a condition in which the heart is unable to pump enough blood to different tissues in the body. In simpler terms, heart failure means a drastic reduction in the function of the heart, meaning that the contraction or expansion of the heart is reduced and it cannot pump enough blood. A heart attack is the most common cause of heart failure that destroys both some heart muscle cells and the ability of these cells to contract. Therefore, the contraction power of the heart decreases. In the early stages of the disease, the patient may not exhibit any visible symptoms. However, it may gradually develop as the patient shows sign of premature fatigue, shortness of breath, decreased energy, shortness of breath during activity, and in more severe cases when the patient is at rest, palpitations, and irregular heartbeats.
Some treatments for heart failure, include medications, surgery, and in more severe cases, a heart transplant. Prolonged treatment, high costs, and risks during operation are some of the reasons that researchers are looking for new ways to treat patients with heart failure.
