September: Peripheral Artery Disease (PAD) Awareness Month

What You Need to Know

Peripheral Artery Disease (PAD) is a serious circulatory condition that affects millions worldwide, yet it remains underdiagnosed and undertreated. PAD occurs when narrowed arteries reduce blood flow to the limbs, typically the legs, due to the buildup of fatty deposits (atherosclerosis). This restricted blood flow can lead to pain, difficulty walking, and other complications if not addressed early.

PAD affects 12-14% of the world’s population.

~13% of the World’s population are affected

20-50% are asymptomatic, they do not experience pain

50% die within 4 years after amputation

Key Symptoms of PAD:

• Leg Pain (Claudication): Pain, cramping, or fatigue in the leg muscles, especially during walking or exercise. This is a common sign of PAD.

• Numbness or Weakness: PAD can cause weakness or numbness in the legs.

• Coldness in One Leg: Poor circulation often leads to coldness in the affected leg.

• Non-Healing Sores or Ulcers: These can appear on the toes, feet, or legs and may signal serious blood flow issues.

• Color Changes in the Skin: Pale, bluish, or darkened skin is a sign of reduced circulation.

• Weak Pulse in Legs or Feet: This may indicate advanced PAD.

Potential Complications:

• Critical Limb Ischemia: A severe reduction in blood flow that can lead to gangrene and possible amputation.

• Heart Attack & Stroke Risk: PAD is closely linked to a higher risk of heart attack and stroke due to widespread atherosclerosis.

Diagnosis and Management:

• Diagnosis typically involves a physical exam, the Ankle-Brachial Index (ABI), and imaging tests like Doppler ultrasound or CT angiography.

• Managing PAD includes lifestyle changes such as quitting smoking, regular exercise, and a healthy diet. Medications and surgical procedures like angioplasty or bypass surgery may be necessary in severe cases.

Why Early Detection Matters: Understanding PAD’s symptoms and seeking timely medical care can prevent serious complications. Early diagnosis allows for better management and improves the quality of life for those affected.

This PAD Awareness Month, let’s raise awareness and encourage proactive vascular health by understanding the signs and risks. Taking care of your arteries means taking care of your entire cardiovascular system!
