Which of the following lifestyle changes is essential for diabetic patients in managing CAD?

Good glucose control is essential for diabetic patients in managing coronary artery disease (CAD) because maintaining stable and optimal blood sugar levels can significantly reduce the risk of cardiovascular complications. For individuals with diabetes, hyperglycemia can lead to multiple detrimental effects on the cardiovascular system, including endothelial dysfunction, increased inflammation, and accelerated atherosclerosis. These factors contribute to a higher risk of heart attacks and other cardiovascular events.

By managing blood glucose levels effectively, patients not only improve their overall health and quality of life but also mitigate the risk of progression of coronary artery disease. Tight control of blood sugar can help lower the incidence of microvascular and macrovascular complications associated with diabetes.

In contrast, increased sugar intake, poor glucose control, or a high carbohydrate diet would all worsen glycemic control and increase the risk of cardiovascular complications, making them unsuitable recommendations for diabetic patients. The focus should always be on lifestyle changes that promote good glucose management to keep patients' risks at bay.
