Congestive heart failure in children

Congestive heart failure in children is due to impaired heart function. Although the compensatory ability is exerted, the cardiac output still cannot meet the metabolic needs of the whole body tissue at rest or activity, so blood stasis occurs in relevant parts of the body, resulting in A series of clinical symptoms and signs are common clinical syndromes. According to the acute onset of congestive heart failure, it can be divided into acute congestive heart failure and chronic congestive heart failure; according to the sequence of left and right ventricular onset, it can be divided into left ventricular failure and right ventricular failure; according to hemodynamics during heart failure The changes can be divided into low cardiac output and high cardiac output in heart failure. The latter, such as severe anemia or arteriovenous fistula, etc., even if the cardiac function is not significantly reduced, the cardiac output is normal or correspondingly increased, dare not meet the needs, and heart failure occurs. Chronic low cardiac output and congestive heart failure are more common clinically. The clinical signs of heart failure are mainly caused by cardiac compensatory dysfunction, sympathetic nerve stimulation, venous congestion, increased blood volume, and sodium and water retention.
