What Is Peripheral Artery Disease in Seniors?
Peripheral artery disease affects circulation to the legs and can lead to serious complications. Understanding PAD helps seniors recognize symptoms and reduce risk of limb loss.
Understanding PAD
Peripheral artery disease occurs when arteries carrying blood to the legs become narrowed or blocked by atherosclerosis. Reduced blood flow causes symptoms and, when severe, threatens limb viability.
PAD affects about 12 to 20 percent of adults over 60. Risk increases with age, smoking, diabetes, high blood pressure, and high cholesterol. The same process affects arteries throughout the body.
PAD indicates systemic atherosclerosis. Those with PAD have high rates of heart disease and stroke. The leg symptoms may be most noticeable, but cardiovascular risk is the bigger threat to life.
Symptoms of PAD
Claudication is the classic symptom. Leg pain, cramping, or fatigue occurs with walking and resolves with rest. The calf is most commonly affected, but thigh or buttock pain can occur.
The pain occurs because exercising muscles need more blood than narrowed arteries can deliver. Resting reduces demand, allowing blood flow to catch up. The pattern of pain with walking that resolves with rest is characteristic.
Rest pain indicates more severe disease. When blood flow is inadequate even at rest, continuous pain occurs, typically in the foot. This is a serious warning sign.
Wounds that do not heal indicate critical limb ischemia. Without adequate blood flow, injuries cannot heal. Non-healing wounds can progress to gangrene and amputation.
Many people with PAD have no symptoms. The disease may be discovered through screening or evaluation for other reasons.
Diagnosis
Ankle-brachial index is the primary screening test. Blood pressure is measured at the ankle and arm. A ratio below 0.9 indicates PAD. This simple, painless test identifies disease.
Further imaging may be needed to plan treatment. Ultrasound, CT angiography, or conventional angiography shows blockage location and severity.
Treatment
Risk factor modification is essential. Smoking cessation is critical. Blood pressure, cholesterol, and diabetes control reduce progression. These measures also reduce heart attack and stroke risk.
Exercise therapy improves claudication. Supervised walking programs increase pain-free walking distance. Exercise stimulates collateral blood vessel development.
Medications help manage PAD. Antiplatelet drugs reduce cardiovascular events. Cilostazol may improve walking distance. Statins reduce cardiovascular risk and may improve leg symptoms.
Revascularization restores blood flow when medications and exercise are insufficient. Angioplasty, stenting, or bypass surgery open or bypass blocked arteries. Severe disease threatening the limb requires intervention.
