Which of the following can be a result of poorly managed heart failure?

Cardiogenic shock is a severe condition that can arise as a result of poorly managed heart failure. In heart failure, the heart's ability to pump blood effectively is compromised. If this situation worsens and the heart cannot maintain adequate circulation to meet the body's needs, it can lead to cardiogenic shock. This condition is characterized by a significant drop in blood pressure and reduced blood flow to vital organs, causing symptoms such as confusion, rapid breathing, and cold, clammy skin.

Cardiogenic shock is particularly critical as it poses an immediate threat to life, necessitating rapid intervention to restore blood flow and stabilize the patient. It highlights the importance of proper management and treatment of heart failure, which includes medications, lifestyle modifications, and ongoing monitoring to prevent such severe complications.

The other options listed, while they may be associated with heart failure in some contexts, do not directly result from the acute deterioration in heart function in the same manner as cardiogenic shock.
