Claudication

Overview

Claudication refers to leg pain, cramping, or fatigue that occurs during walking or physical activity and improves with rest. It is commonly a sign of reduced blood flow to the muscles, most often due to peripheral artery disease (PAD). This condition affects circulation and may indicate underlying cardiovascular issues.

Early diagnosis is important, as claudication may reflect broader arterial disease that increases the risk of heart attack or stroke. At Cardiology Care NYC, we assess circulatory health and provide treatment plans to improve mobility and prevent complications.

Causes

Claudication develops when narrowed or blocked arteries reduce blood supply to the leg muscles during activity.

Common causes include:

• Peripheral artery disease (PAD)
• Atherosclerosis (plaque buildup in the arteries)
• Diabetes-related arterial damage
• High cholesterol
• Smoking-related vascular changes
• High blood pressure
• Sedentary lifestyle
• Aging and decreased arterial elasticity

Symptoms

Claudication symptoms usually appear during physical exertion and improve after resting.

Common signs include:

• Cramping, aching, or tightness in the calves, thighs, or buttocks
• Leg pain triggered by walking or climbing stairs
• Muscle weakness or heaviness in the legs
• Coldness or discoloration in the lower limbs
• Numbness or tingling sensations
• Slow-healing wounds on the feet or legs (in advanced cases)

If symptoms worsen or begin occurring at rest, immediate medical evaluation is needed.

Diagnosis

At Cardiology Care NYC, diagnosis focuses on assessing blood flow, vascular health, and cardiovascular risk factors.

Diagnostic testing may include:

• Medical history and physical examination
• Ankle-Brachial Index (ABI) to compare blood pressure in the ankle and arm
• Doppler ultrasound to evaluate blood flow in leg arteries
• Vascular ultrasound imaging
• Blood tests for cholesterol, glucose, and inflammation markers
• Stress testing or circulation assessments during activity
• Comprehensive cardiovascular screening

Treatment

Treatment for claudication aims to improve blood circulation, reduce symptoms, and prevent progression of artery disease.

Lifestyle Modifications

• Engage in supervised walking or aerobic exercise programs
• Quit smoking
• Follow a heart-healthy, low-cholesterol diet
• Maintain a healthy weight
• Control blood pressure and blood sugar levels

Medications

Medications may be recommended to improve circulation and reduce cardiovascular risk, such as:

• Antiplatelet medications to improve blood flow
• Cholesterol-lowering medications (e.g., statins)
• Medications to improve walking distance and reduce leg pain
• Blood pressure and diabetes management drugs

Ongoing Care

Regular follow-up is essential to track progress, adjust treatment, and maintain cardiovascular health. Our team provides guidance to improve walking tolerance and protect long-term vascular function.

When To See A Doctor

Schedule a cardiology consultation if you experience:

• Leg pain or cramps that occur during activity and improve with rest
• Fatigue or heaviness in the legs
• Persistent coldness or color changes in the lower legs or feet
• Difficulty walking due to recurring leg discomfort

At Cardiology Care NYC, we provide comprehensive care to restore circulation, relieve symptoms, and protect long-term heart and vascular health.
