Which symptom is NOT commonly associated with right-sided heart failure?

Frequent headaches are not a common symptom associated with right-sided heart failure. Right-sided heart failure primarily leads to systemic venous congestion, which contributes to symptoms such as jugular venous distention, edema, and cool extremities due to poor circulation and fluid retention.

Jugular venous distention occurs because the right side of the heart struggles to pump blood effectively, leading to increased pressure in the veins. Edema is also prevalent as fluid backs up in tissues, especially in the lower extremities. Cool extremities can occur due to reduced blood flow as the cardiovascular system is compromised.

In contrast, headaches are not directly linked to the physiological changes associated with right-sided heart failure. While some patients may experience headaches for various reasons, they are not a hallmark sign of this condition, making it the correct choice in identifying a symptom that is not typically associated with right-sided heart failure.
