What is a common sign of malnutrition due to heart problems?

Cardiac cachexia is a recognized syndrome associated with heart failure, characterized by involuntary weight loss, muscle wasting, and a decline in health, often resulting from malnutrition. This condition occurs as a result of the body's inability to intake adequate nutrition while simultaneously facing increased metabolic demands due to compromised heart function. Patients may experience profound fatigue and a loss of muscle mass, which distinguishes cardio cachexia from other conditions that might involve weight gain or enhanced stamina.

In contrast, the other options typically reflect scenarios that do not align with malnutrition secondary to heart problems. Weight gain may occur in some heart patients, particularly those retaining fluids, but it is not indicative of malnutrition. Increased appetite is usually absent in cases of malnutrition, especially in those experiencing cardiac issues, as their condition often leads to changes in metabolism and reduced desire to eat. Enhanced stamina is also contrary to the effects of malnutrition and heart problems; rather, individuals may experience increased fatigue and reduced physical capability. Thus, cardiac cachexia is the primary concern in this context, representing the complex interplay between malnutrition and heart disease.
