Which symptom is commonly associated with left-sided heart failure?

Left-sided heart failure primarily affects the heart's ability to pump blood effectively to the body. As a result, blood can back up into the lungs, leading to fluid accumulation in that area, known as pulmonary edema. This condition manifests as symptoms such as shortness of breath, particularly when lying down, and a persistent cough that may produce pink, frothy sputum.

The presence of pulmonary edema is a hallmark of left-sided heart failure, indicating the lung's inability to properly exchange gases due to fluid buildup. While peripheral edema and jugular venous distention are more related to right-sided heart failure, and liver damage is typically a consequence of chronic heart failure affecting multiple systems, pulmonary edema distinctly aligns with the pathophysiology of left-sided heart failure. Thus, option C is clearly related to the condition in question.
