Which of the following are risk factors for arterial insufficiency?

1. Diabetes

2. Smoking

3. Cardiovascular disease

4. All are true

The correct answer is: All are true

Arterial insufficiency is a condition characterized by reduced blood flow through the arteries, which can lead to various complications such as pain and ulceration. Each of the listed factors is a recognized risk factor for developing arterial insufficiency. Diabetes can lead to damage of the blood vessels due to elevated blood glucose levels over time, increasing the likelihood of arterial disease. Hyperglycemia contributes to the thickening of artery walls and can promote atherosclerosis, which restricts blood flow. Smoking is another significant risk factor because it introduces harmful chemicals into the bloodstream and damages the lining of blood vessels. This harm can lead to atherosclerosis and further compromise arterial circulation. Cardiovascular disease includes a range of conditions, such as coronary artery disease and peripheral artery disease, that directly affect blood circulation. The presence of cardiovascular disease often correlates with underlying issues related to arterial insufficiency, as these conditions involve compromised blood flow. Since all three risk factors contribute to the likelihood of developing arterial insufficiency, the correct answer encompasses all these factors, reinforcing the understanding that arterial health is influenced by multiple interconnected risk elements.
