Which condition involves heart pump failure with fluid backup that may or may not be related to smoking history?

Explanation:
Heart pump failure with fluid backup describes congestive heart failure. When the heart’s pumping ability is reduced, pressures back up into the venous system, leading to edema and fluid accumulation in the lungs (pulmonary edema). This results in shortness of breath and can cause crackles on exam, orthopnea, and other signs of fluid overload. The smoking history is only a risk factor for heart disease; it isn’t required for CHF, which can arise from high blood pressure, prior heart attack, valve disease, or cardiomyopathy. The other options are lung- or infection-related conditions (airway obstruction from COPD, viral infection with RSV, or tuberculosis), which don’t center on the heart’s pumping failure with fluid backup.
