What condition is characterized by the heart's inability to pump sufficient blood to the body?

The condition characterized by the heart's inability to pump sufficient blood to the body is congestive heart failure (CHF). In CHF, the heart's pumping capacity is compromised, which can result from various underlying issues such as weakened heart muscle (systolic failure) or stiff heart muscle (diastolic failure). As a result, the heart cannot maintain adequate blood flow to meet the body’s needs, leading to symptoms such as fatigue, shortness of breath, and fluid buildup.

Understanding CHF is crucial as it reflects a broader category of heart failure issues that can stem from conditions like coronary artery disease, high blood pressure, or previous heart attacks. Unlike the other conditions listed, which either affect the blood flow in specific locations or involve pressure issues around the heart, CHF is a systemic problem affecting the heart's overall ability to function effectively.
