Which of the following is a risk factor for developing heart failure in diabetics?

Insulin resistance is a significant risk factor for developing heart failure, particularly in individuals with diabetes. This condition is characterized by the body's cells becoming less responsive to insulin, leading to elevated blood sugar levels and increased systemic inflammation, which can adversely affect heart function over time. The prolonged exposure to high glucose levels can lead to damage in the heart muscle and vascular system, ultimately increasing the risk of heart failure.

On the other hand, high fiber intake is generally beneficial for overall cardiovascular health, as it can help regulate blood sugar levels and improve cholesterol profiles. Low blood pressure is not typically associated with increased heart failure risk; in fact, it may indicate better cardiovascular health in some cases. Regular aerobic exercise is another protective factor against heart failure, helping to improve heart health and reduce weight, thereby mitigating some of the risk associated with diabetes. Thus, insulin resistance stands out as a clear risk factor for heart failure among diabetics.
