What physical sign may indicate worsening heart failure?

Peripheral edema is a physical sign that may indicate worsening heart failure. In heart failure, the heart's ability to pump blood effectively is compromised, leading to an accumulation of fluids in the tissues, particularly in the legs and feet. This condition occurs because the body retains sodium and water, which causes swelling in the lower extremities.

As heart failure progresses, the severity of peripheral edema typically increases, indicating that the body's compensatory mechanisms are failing to maintain adequate circulation and fluid balance. Monitoring for peripheral edema is essential in patients with heart failure, as its presence can signal an exacerbation of the condition, requiring timely intervention and management to prevent further complications.
