HF with reduced ejection fraction

Least common cause for bilateral pedal edema

Chronic vascular insufficiency. ***Chronic vascular insufficiency*** - While chronic venous insufficiency is a common cause of bilateral pedal edema, **arterial insufficiency** (a type of chronic vascular insufficiency) is a much less common cause of pure edema and is more often associated with **ischemic pain**, **ulcers**, and **skin atrophy** [1]. - **Arterial insufficiency** primarily causes limb ischemia rather than significant edema, differentiating it from situations where fluid retention is the primary issue [2]. *CKD* - **Chronic kidney disease (CKD)** leads to impaired fluid and sodium excretion, causing generalized fluid overload. - This fluid overload commonly manifests as **bilateral pedal edema** due to gravity-dependent fluid accumulation. *CLD* - **Chronic liver disease (CLD)**, particularly cirrhosis, results in **portal hypertension** and decreased hepatic synthesis of **albumin**. - This leads to reduced oncotic pressure and increased hydrostatic pressure, driving fluid into the extravascular space, often causing **ascites** and **bilateral pedal edema**. *HF with reduced ejection fraction* - **Heart failure with reduced ejection fraction (HFrEF)** impairs the heart's ability to pump blood effectively, leading to fluid backup in the venous system [2]. - This increased hydrostatic pressure in the peripheral capillaries directly causes **bilateral pedal edema** as fluid extravasates into the interstitial space [2].
