Left-sided heart failure is most commonly associated with which of the following symptom clusters?

• A. Pulmonary edema, dyspnea, orthopnea, paroxysmal nocturnal dyspnea
• B. Peripheral edema and ascites
• C. Jaundice and pruritus
• D. Hypotension and tachycardia

Answer: (A)

Left-sided heart failure causes backward pressure into the lungs, leading to pulmonary venous congestion. This produces the classic respiratory symptom cluster: pulmonary edema with shortness of breath, trouble breathing when lying flat (orthopnea), and episodes of nocturnal breathlessness (paroxysmal nocturnal dyspnea). These signs reflect fluid backing up into the lungs and impaired gas exchange.

In contrast, signs like peripheral edema and ascites arise from right-sided failure and systemic venous congestion, while jaundice/pruritus point to liver-related issues, and hypotension with tachycardia are not the defining pulmonary-focused features of left-sided failure.
