Congestive heart failure is a pathophysiological condition in which the heart's output is insufficient to meet the needs of the body and lungs. [10] The term "congestive heart failure" is often used because one of the most common symptoms is congestion or fluid accumulation in the tissues and veins of the lungs or other parts of a person's body ...
Eventually, the fluid enters the air spaces in the lungs (pulmonary edema) reduces the amount of oxygen that can enter the blood, leading to anemia and causes shortness of breath or enters pleural space by transudation (pleural effusion which also causes dyspnea), which is the best indicator of estimating central venous pressure is increased ...
There is a circulatory overload which may lead to pulmonary edema secondary to an elevated diastolic pressure in the left ventricle. These individuals usually have a normal systolic function but symptoms are those of heart failure. With time, this overload causes systolic failure. Ultimately cardiac output can be reduced to very low levels. [1]
Causes of edema that are generalized to the whole body can cause edema in multiple organs and peripherally. For example, severe heart failure can cause pulmonary edema, pleural effusions, ascites and peripheral edema. Such severe systemic edema is called anasarca. In rare cases, a parvovirus B19 infection may cause generalized edemas. [9]
The development of pulmonary edema may be associated with symptoms and signs of "fluid overload" in the lungs; this is a non-specific term to describe the manifestations of right ventricular failure on the rest of the body. These symptoms may include peripheral edema (swelling of the legs, in general, of the "pitting" variety, wherein the skin ...
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
The symptoms of TACO can include shortness of breath , low blood oxygen levels , leg swelling (peripheral edema), high blood pressure (hypertension), and a high heart rate (tachycardia). [ 3 ] It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [ 2 ]
