Which condition is characterized by the heart's inability to pump sufficient blood, leading to inadequate organ perfusion?

The condition characterized by the heart's inability to pump sufficient blood, leading to inadequate organ perfusion, is congestive heart failure. In this condition, the heart's efficiency diminishes, which means it cannot effectively circulate blood throughout the body. Consequently, vital organs do not receive the necessary oxygen and nutrients, which can lead to symptoms such as fatigue, shortness of breath, and fluid retention.

Congestive heart failure can result from several underlying issues, including previous heart attacks, high blood pressure, or other cardiovascular diseases. The focus is on that impaired ability to maintain adequate circulation, distinguishing it from other conditions that may affect the blood vessels or contribute to increased pressure, but do not inherently involve the heart's pumping function itself.
