Which of the following is not a symptom of right-sided heart failure?

In the context of right-sided heart failure, symptoms are typically related to the body's inability to manage blood flow effectively, leading to fluid accumulation and various physical manifestations. Right-sided heart failure often results in symptoms such as pitting edema, ascites, and cold extremities due to poor circulation and fluid retention.

Increased physical activity, on the other hand, is not a symptom of right-sided heart failure. In fact, individuals with heart failure generally experience limitations in their ability to engage in physical activity due to fatigue, dyspnea, and overall reduced exercise tolerance. This is a significant factor that differentiates heart failure symptoms, as affected individuals may often find themselves less able to participate in regular activities, leading to a more sedentary lifestyle. Thus, the presence of increased physical activity would not align with the expected manifestations of right-sided heart failure.
