What Does Liquid Retention Mean?

Fluid retention is a clinical manifestation of patients with multi-organ failure and acute myocardial infarction. Heart failure is also known as congestive heart failure or cardiac dysfunction. The heart is weakened due to disease, overexertion, and reduced blood pumping function, so that the blood volume cannot meet the metabolic needs of organs and tissues. The main symptoms are dyspnea, wheezing, edema, etc. Due to the weakening of myocardial contractility and the decrease of cardiac output, there is insufficient perfusion of tissues and organs, accompanied by manifestations of pulmonary or systemic circulation congestion. Reasons for fluid retention: 1. Heart failure refers to heart failure caused by primary myofibrillar contractile dysfunction of the myocardium, where pump dysfunction is primary. When the myocardium is unable to contract strongly due to various reasons and cannot eject enough blood into the peripheral vessels to meet the needs of systemic tissue metabolism, heart failure occurs. 2. Heart failure caused by other reasons: For example, in valvular heart disease, myocardial hypertrophy and cardiac dilation occur due to excessive myocardial load, which leads to relative insufficiency of myocardial contractility and heart failure. At this time, pump dysfunction is secondary and easier to reverse when the valvular obstacle is removed. 3. Heart failure caused by reasons other than the myocardium often accompanies myocardial damage in the late stage. 4. Diseases of the heart itself, such as congenital heart disease, myocarditis, cardiomyopathy, severe arrhythmia, endocarditis, etc., as well as diseases outside the heart, such as acute nephritis, toxic pneumonia, severe anemia, hemolysis, large amounts of intravenous fluid infusion, and complications after surgical operations, can also cause heart failure.
