Fluid retention is a clinical manifestation of patients with multiple organ failure and acute myocardial infarction, among others. Heart failure is also known as congestive heart failure or cardiac insufficiency. The heart is weakened by disease, overwork, and blood expulsion to the extent that the amount of blood expelled cannot meet the metabolic needs of organs and tissues. The main symptoms are dyspnea, wheezing, and edema. Due to weakened myocardial contractility cardiac blood excretion decreases to the point where tissue and organ perfusion is inadequate along with manifestations of stasis in the pulmonary or and body circulation. Etiology of fluid retention Dilated cardiomyopathy: Dilated cardiomyopathy (DCM) is a common type of primary cardiomyopathy characterized by significant enlargement of the left ventricle (most) or right ventricle, both with varying degrees of myocardial hypertrophy and reduced ventricular systolic function, with enlarged heart, heart failure, arrhythmias, and embolism as the basic features. It was previously referred to as congestive cardiomyopathy. The disease is often accompanied by arrhythmias, with progressive exacerbation. Death can occur at any stage of the disease, and about 20% of patients with DCM have a family history of cardiomyopathy. About 20% of patients with DCM have a family history of cardiomyopathy. The majority of patients are middle-aged. The onset of the disease is mostly slow, sometimes up to 10 years or more. The symptoms are mainly congestive heart failure, with shortness of breath and edema being the most common. Initially, shortness of breath occurs after labor or exertion, and later, shortness of breath may occur with light activity or rest, or with paroxysmal dyspnea at night. Patients often feel weak. Diastolic heart failure (DHF): is a clinical syndrome of the pulmonary or physical circulation due to abnormal ventricular filling and elevated filling pressures in the presence of normal ventricular systolic function. Chronic heart failure: The clinical manifestations of chronic heart failure are closely related to which side of the ventricle or atrium is involved. Left heart failure is the most common clinical condition. The clinical features of left heart failure are mainly pulmonary stasis and pulmonary edema due to left atrial and/or right ventricular failure, while the clinical features of right heart failure are venous stasis and water and sodium retention in the body circulation due to right atrial and/or right ventricular failure. Left heart failure is often followed by functional impairment of the right heart, eventually leading to total heart failure. In the presence of right heart failure, the symptoms of left heart failure may be reduced.
