What type of edema is most commonly associated with right-sided heart failure?

The type of edema most commonly associated with right-sided heart failure is indeed peripheral edema. In right-sided heart failure, the right ventricle is unable to effectively pump blood to the lungs for oxygenation, which leads to a buildup of blood in the systemic circulation. This increased pressure in the veins causes fluid to leak out into the surrounding tissues, resulting in swelling, primarily in the extremities such as the legs, ankles, and feet.

Furthermore, peripheral edema can be observed in conditions that elevate venous pressure or impact the body’s fluid balance, making it a key clinical manifestation of right-sided heart failure. Unlike pulmonary edema, which is more closely associated with left-sided heart failure, the characteristics of peripheral edema, including its bilateral nature and dependence on gravity, make it particularly indicative of right heart dysfunction.
