Peripheral Artery Disease (PAD) is a chronic condition caused by atherosclerosis that leads to insufficient blood supply to the limbs, which can result in amputation or heart disease in severe cases. Preventing this disease requires controlling risk factors, adjusting lifestyle habits, and undergoing regular health check-ups. Through proactive management, the risk of developing the disease can be significantly reduced, and the progression of the condition can be delayed.
Preventing peripheral artery disease not only involves medical intervention but also requires personal daily health maintenance. Measures such as quitting smoking, controlling blood pressure and blood sugar, and improving dietary structure can effectively reduce the formation of arterial plaques. Regular arterial health screenings, especially for high-risk groups, can help detect abnormalities early and take action.
Managing the main risk factors is key to preventing peripheral artery disease. Nicotine in tobacco directly damages endothelial cells in blood vessels, promoting plaque formation; therefore, quitting smoking is the most important first step. Studies show that the risk of arterial blockage can be reduced by more than 50% after smokers quit.
Blood pressure and blood sugar control should be approached with both medication and lifestyle changes. Hypertensive patients should aim to keep their systolic blood pressure below 140/90 mmHg, while diabetic patients need to maintain their hemoglobin A1c (HbA1c) below 7%. It is recommended to undergo blood tests for relevant indicators every 3-6 months.
Changes in lifestyle can significantly improve arterial health. Regular aerobic exercise can promote the formation of collateral circulation; it is recommended to engage in 150 minutes of moderate-intensity exercise each week, such as brisk walking or swimming. Avoid sedentary behavior; getting up to move for 5 minutes every hour can improve blood flow to the lower limbs.
Controlling weight to a BMI below 25 can reduce metabolic stress. For abdominal obesity (waist circumference >90 cm for men, >80 cm for women), combining core muscle training with dietary control is necessary. Stress management should not be overlooked, as long-term stress can lead to increased vascular constriction and inflammation.
The Mediterranean diet has been shown to reduce the risk of atherosclerosis. It is recommended to consume 25-30 grams of fiber daily, sourced from whole grains, legumes, and vegetables. Reduce intake of trans fats and keep saturated fats to less than 7% of total caloric intake.
Increase sources of Omega-3 fatty acids, such as deep-sea fish (salmon, trout) twice a week. Use olive oil instead of animal fats, and limit sodium intake in processed foods (less than 2000 mg per day). Supplementing with folic acid, vitamin B12, and B6 can lower homocysteine levels, indirectly protecting the endothelial lining of blood vessels.
Exercise training should follow the FITT principle: Frequency (5 times a week), Intensity (heart rate at 60-70% of maximum), Time (30 minutes each session), Type (primarily aerobic exercise). Patients with intermittent claudication can engage in monitored walking training, gradually increasing walking distance.
Resistance training is recommended using a low weight, high repetition model, focusing on thigh and gluteal muscle training, followed by 10 minutes of stretching after each training session. During winter outings, proper body warmth should be maintained to avoid exacerbating ischemia due to vascular constriction.
Individuals over 50 or those with diabetes should undergo an annual Ankle-Brachial Index (ABI) check, with normal values being >0.9. If ABI <0.8, further vascular ultrasound or CT angiography is required. Men over 45 or those with a family history should have lipid checks every two years.
High-risk groups are advised to undergo foot vascular blood flow checks every six months and regularly monitor changes in foot skin temperature. Using pulse wave sensors for home monitoring can help detect changes in blood flow dynamics early.
Work environments that require prolonged standing or sitting need special attention to limb circulation. Office workers are advised to perform ankle rotations and leg lifts every hour and use adjustable-height standing desks. Workers exposed to high temperatures should replenish electrolytes to avoid dehydration, which can increase blood viscosity.
Patients living in cold areas should enhance limb warmth by using electric blankets or wearing gradient compression socks. Maintain a constant indoor temperature of 20-22°C to avoid excessive vascular constriction due to temperature differences.
If experiencing painless swelling in the lower limbs, skin ulcers that do not heal easily, or unexplained cramps while walking, immediate medical evaluation is necessary. Patients with existing hypertension or diabetes should discuss their arterial health status with their physician every six months.
Those with a family history of early-onset cardiovascular disease should begin regular screenings at age 40. Patients undergoing chemotherapy or long-term steroid use should increase the frequency of arterial health monitoring.
Through the above multi-faceted prevention strategies, the risk of developing peripheral artery disease can be reduced by more than 60%. Maintaining an active lifestyle, along with regular medical follow-ups, is the best way to preserve arterial health. Start adjusting your diet, increasing physical activity, and maintaining close communication with your healthcare team to effectively lower your risk of disease.
Regular aerobic exercise (such as brisk walking or cycling) promotes the generation of collateral blood vessels, improves blood supply to the limbs, and reduces the risk of thrombosis. Additionally, exercise helps control blood sugar, blood pressure, and weight, indirectly reducing the progression of atherosclerosis; it is recommended to engage in at least 150 minutes of moderate-intensity exercise each week.
Which dietary components exacerbate arterial narrowing, and how should adjustments be made?A diet high in saturated fats, trans fats, and sodium accelerates atherosclerosis and increases the risk of narrowing. It is recommended to increase intake of deep-sea fish rich in Omega-3 fatty acids, antioxidant-rich fruits and vegetables, and replace refined carbohydrates with whole grains, along with low-fat dairy products to help reduce the risk of disease.
What is the relationship between peripheral artery disease and hyperlipidemia? How should it be monitored?Excessive low-density lipoprotein (LDL) in the blood deposits in the arterial walls, forming plaques that lead to peripheral artery obstruction. Patients should check their lipid levels every 3-6 months, with a target LDL level of <2.6 mmol/L; high-risk individuals may need even lower levels, along with statin therapy.
How can early symptoms such as intermittent claudication be misinterpreted as aging, and how can they be distinguished?Pain in the lower limb muscles while walking (intermittent claudication) is a typical symptom but is often mistaken for arthritis or decreased physical ability. If the pain quickly alleviates after resting and recurs upon activity, immediate examination is necessary. Other warning signs include cold limbs, hair loss, or wounds that take a long time to heal, which should prompt discussion with a physician about arterial ultrasound or angiography.
Can vascular function return to normal after quitting smoking? How long does it take?Within 24 hours of quitting smoking, carbon monoxide levels decrease, and peripheral blood flow responses begin to improve within 2-12 weeks. After one year, the risk of myocardial infarction is reduced by half. Although established atherosclerosis cannot be reversed, quitting smoking can significantly delay disease progression and reduce the risk of amputation or cardiovascular events.
