Which of the following is a common symptom of congestive heart failure during ambulation?

In congestive heart failure, the body struggles to effectively pump blood, leading to a range of symptoms that can be exacerbated during physical activities such as ambulation. Dyspnea, or difficulty breathing, is a particularly common symptom associated with congestive heart failure. This symptom arises due to fluid accumulation in the lungs (pulmonary congestion), which can become more pronounced during exertion. As a person walks or engages in physical activity, the increased demand for oxygen can lead to greater difficulty in breathing.

While chest pain, palpitations, and dizziness may occur in some cases of congestive heart failure, they are not as universally experienced during ambulation. Dyspnea specifically highlights the limitations in respiratory function that patients with heart failure may face, making it the most relevant symptom linked to physical activity in this condition.
