Which cardiovascular finding is commonly associated with acute decompensated heart failure?

• A. Bradycardia
• B. Tachycardia
• C. Hypotension
• D. Cold, clammy skin

Answer: (B)

When the heart suddenly struggles to pump blood, the body mounts a quick compensatory response to preserve organ perfusion. The most common cardiovascular sign is tachycardia, because increasing the heart rate helps raise overall cardiac output when the stroke volume is falling. This sympathetic drive also heightens contractility and causes some peripheral vasoconstriction to support blood pressure. While hypotension or cold, clammy skin can occur in more severe cases, they are not as consistently present as tachycardia in acute decompensated heart failure. Bradycardia would worsen perfusion, so it isn’t typical in this scenario.
