Peripheral artery disease (PAD) is a condition in which the arteries outside the heart and brain, particularly in the legs, become narrowed or blocked by plaque buildup. This reduces blood flow to the limbs, leading to pain, fatigue, or numbness. PAD is closely linked to coronary artery disease (CAD) and shares similar risk factors, making early detection and treatment critical to preventing serious cardiovascular events. At Premier Cardiology, we provide comprehensive care for PAD, from diagnosis to advanced interventions, helping patients maintain mobility, manage symptoms, and reduce cardiovascular risk.
Causes and Risk Factors
PAD is primarily caused by atherosclerosis, the buildup of plaque in the arteries. Risk factors include:
- High blood pressure
- High cholesterol
- Diabetes
- Smoking
- Obesity
- Sedentary lifestyle
- Age (risk increases after 50)
- Family history of cardiovascular disease
Patients with PAD often have other cardiovascular conditions such as CAD, increasing their risk for heart attack or stroke.
Symptoms of PAD
PAD symptoms can vary depending on the severity of arterial blockage. Common signs include:
- Leg pain or cramping during walking or exercise (claudication)
- Numbness, weakness, or heaviness in the legs
- Coldness in the lower legs or feet
- Slow-healing sores or ulcers on the feet or legs
- Change in skin color or hair loss on the legs
- Weak or absent pulses in the legs
Some individuals may have PAD without noticeable symptoms, which is why routine screening is recommended for high-risk patients.
Diagnosis
Diagnosing PAD involves physical examination and specialized tests to assess blood flow:
- Ankle-Brachial Index (ABI) – Compares blood pressure in the ankle and arm to detect blockages
- Duplex Ultrasound – Uses sound waves to visualize arteries and measure blood flow
- CT Angiography or MRI Angiography – Detailed imaging of the arteries
- Blood tests – Evaluate cholesterol, blood sugar, and kidney function
Treatment Options
Treatment for PAD focuses on relieving symptoms, improving circulation, and reducing cardiovascular risk.
Lifestyle Modifications
- Regular exercise, especially supervised walking programs
- Smoking cessation
- Heart-healthy diet to manage cholesterol and blood pressure
- Weight management
Medications
- Antiplatelet medications to prevent blood clots
- Cholesterol-lowering drugs
- Medications to improve walking distance and reduce leg pain
Interventional Procedures
For severe or lifestyle-limiting PAD, advanced interventions may be necessary:
- Angioplasty and Stenting – Opens blocked arteries using a balloon and stent
- Atherectomy – Removes plaque from the arteries
- Bypass Surgery – Creates an alternate pathway for blood flow around blockages
Preventing Complications
Managing High Blood Pressure, High Cholesterol, Obesity, and diabetes is essential to prevent PAD progression and reduce cardiovascular risks such as heart attack and stroke. Early detection, lifestyle changes, medications, and regular follow-up can maintain circulation and improve overall quality of life.
