Congestive Heart Failure
Congestive heart failure is an older name for heart failure. Congestive heart failure takes place when the heart is unable to maintain an adequate circulation of blood in the bodily tissues or to pump out the venous blood returned to it by the veins (Merriam-Webster). The heart is split into two distinct pumping structures, the right side of the heart and the left side of the heart. Appropriate cardiac performance involves each ventricle to extract even quantities of blood over intervals. If the volume of blood reimbursed to the heart develops more than both ventricles can manage, the heart can no longer be an efficient pump.

Circumstances that trigger heart failure might involve one or both of the heart’s pumping methods. So, heart failure can be categorized as right-sided heart failure, left-sided heart failure, or biventricular heart failure. The left side of the heart is vital for standard heart function and is typically where heart failure arises. The left atrium obtains oxygen-rich blood from the lungs and pushes it into the left ventricle, the heart’s biggest and greatest pump, which is accountable for delivering blood to the body. Once it has dispersed throughout the body, blood comes back to the right atrium and then journeys to the right ventricle, which pumps it into the lungs to be restocked with oxygen. After the right side loses pumping power, blood can back up in the veins struggling to return blood to the heart.

Right heart failure might happen alone but it is typically a consequence of left-sided failure. When the left side fails, fluid backs up into the lungs and pulmonary pressure is increased. The right ventricle must continually pump blood against this increased fluid and pressure in the pulmonary artery and lungs. Over time this additional strain eventually causes it to fail (William and Hopper). Heart failure can be the result of systolic (contractile) dysfunction, diastolic (relaxation) dysfunction, or a...
