Management of Moderate Peripheral Arterial Disease (PAD) with Atheromatous Changes

Immediate Diagnostic Steps

The American College of Cardiology recommends complete ABI testing with follow-up Doppler imaging to further quantify disease severity and establish a baseline for future comparison 2, 3
Referral to a vascular specialist for comprehensive assessment is indicated in the ultrasound report findings showing moderate PAD with reduced perfusion in the right popliteal artery 2, 3

The European Heart Journal recommends initiating or optimizing statin therapy to achieve LDL-C target <70 mg/dL for high-risk patients 1, 4
The American College of Cardiology suggests implementing antithrombotic therapy, considering a combination of low-dose rivaroxaban plus aspirin if the patient has high ischemic risk and non-high bleeding risk 1
The American College of Cardiology recommends optimizing blood pressure control targeting <140/90 mmHg (or <130/80 mmHg if diabetes or chronic kidney disease is present) 5
Aggressive smoking cessation interventions should be implemented if the patient is a smoker, including counseling, pharmacotherapy, and referral to smoking cessation programs 5

The European Heart Journal recommends prescribing supervised exercise therapy (SET) as a first-line treatment, with a program including at least 30-45 minutes per session, 3 sessions per week, and a minimum duration of 12 weeks 1, 6, 7
If supervised exercise is not available, a structured home-based exercise program with clear guidance on frequency, intensity, and progression should be implemented 1, 6

Regular follow-up visits should be scheduled at least annually to assess clinical and functional status, medication adherence, and cardiovascular risk factors 1, 2, 8
Periodic ABI measurements should be performed to monitor disease progression 2, 8

Revascularization is not indicated at this stage unless the patient has significant lifestyle-limiting symptoms after 3 months of optimal medical therapy and exercise, or evidence of critical limb ischemia 1, 3
If revascularization becomes necessary in the future, the approach should be tailored to the specific anatomical lesion location and morphology 1
