Description

Congestive heart failure is a harmful disorder when the heart is not able to pump blood as effectively as it should. Heart failure does not mean that the heart has stopped or is about to stop beating, it suggests that the ability of the heart muscle to contract has diminished with time or that it has a mechanical problem that prevents it from entirely filling with blood. Anyone may encounter various heart failure symptoms depending on which side of the heart is injured and how serious the condition has become. The bulk of symptoms are caused by the body retaining fluid and by the reduced blood flow to the organs. The body may become too hydrated if the heart beats too slowly. The blood arteries returning blood to the heart cause blood to back up. Blood vessel breaches might cause tissues in the body to get inundated with fluid, which could result in edoema and other difficulties.

The older child's congestive heart failure symptoms are more similar to those of an adult. Breathlessness is a typical symptom of pediatric heart failure. Activity dyspnoea and an enhanced variant of the typical breathlessness reaction to intense activity are almost always present, and their intensity is correlated with the severity of heart failure. Some kids may also have a chronic hacking cough brought on by bronchial mucosa congestion. Weakness and fatigue usually show up much later. Children with mild to moderate heart failure do not appear to be in any distress when physically tested, but those with severe heart failure may be dyspneic at rest. The youngster may look worried yet well-fed if heart failure started relatively suddenly. Children with more chronic heart failure often don't show signs of anxiety but may be underweight and wasted. The heart pumps more quickly to fill up more quickly following a contraction, Yet as time goes on, blood flow decreases, and putting extra effort might cause palpitations in the heart. Additionally, the heart grows a little to accommodate the blood. Breathlessness results from fluid filling the lungs. Lack of blood causes the kidneys to start retaining water and salt, which can cause kidney failure. Heart failure is frequently and generally progressive, meaning it becomes worsen over time, whether or not it receives therapy. Insufficient blood pumping from the left ventricle of the heart results in left-sided heart failure. The pulmonary veins, which transport blood away from the lungs, get clogged with blood as a result. People may have breathing difficulties, shortness of breath, or coughing when this occurs. Blood builds up in the veins that carry blood to the lungs as a result of the right ventricle's inability to pump enough blood. This condition is known as right-sided heart failure these results in fluid leakage into the surrounding tissues from the veins. Usually, fluid collects in the legs, however it can also gather in the abdomen or genital region on occasion. Biventricular heart failure is characterized as occurring in both ventricles of the heart. The signs of both left and right heart failure are present in this kind. Weakness, lethargy, and abrupt renal failure are negative consequences of decreased tissue perfusion. Aspects of both backward and forward failure interact in chronic heart failure to cause clinical symptoms. As a result, the edema and venous hypertension linked to backward failure are also produced by the retention of salt and water brought on by forward failure. On the other hand, inadequate gas exchange in crowded lungs exacerbates muscular weakness and exhaustion brought on by decreased cardiac output and oxygen supply to skeletal muscle. Confusion, memory loss, and lack of attention are all central nervous system symptoms. Along with stomach discomfort and anorexia, this ailment is also accompanied with nausea.

The heart's ability to pump blood is sometimes irreversibly damaged. Nevertheless, by controlling heart failure and assisting in the relief of many symptoms, medicines can considerably enhance quality of life. Doctors also focus on treating the underlying causes of heart failure. The stress on the heart will lessen as a result. To treat the underlying causes of heart failure and to assist manage symptoms, a doctor may occasionally advise surgery. Preoperative clinical diagnosis of heart failure has its limitations, in approximately half of instances, there is no preoperative diagnosis. Making improvements to preoperative heart failure diagnostics is necessary given the hazards of being undetected.
