Study Notes
Asymptomatic Atherosclerosis Screening
- Prevalence of atherosclerosis in coronary, carotid, and renal arteries is higher in patients with PAD than those without PAD.
- Intensive atherosclerosis risk factor modification is justified in patients with PAD, regardless of disease presence in other arterial beds.
- No evidence suggests that screening for asymptomatic atherosclerosis in other arterial beds improves clinical outcomes.
Medical Therapy for PAD
- Antiplatelet, statin, antihypertensive agents, and oral anticoagulation are recommended for patients with PAD.
- Smoking cessation is crucial for patients with PAD, with assistance in quitting through pharmacotherapy and/or referral to a smoking cessation program.
- Glycemic control is beneficial for patients with PAD, particularly those with CLI, to reduce limb-related outcomes.
Peripheral Arterial Diseases
- Peripheral vascular disease (PVD) is a blood circulation disorder that causes blood vessels outside the heart and brain to narrow, block, or spasm.
- Two main types of PVD exist: functional PVD (no physical damage to blood vessels) and organic PVD (changes in blood vessel structure).
Patients at Increased Risk of PAD
- Age ≥65 years
- Age 50-64 years with risk factors for atherosclerosis (e.g., diabetes, smoking, hyperlipidemia, hypertension) or family history of PAD
Diagnosis and Assessment
- Patients with suspected PAD may undergo additional tests (e.g., Doppler ultrasonography, toe cuff measurement) to check for arterial stenosis or occlusions.
- Ischemic lesions are unlikely to heal when systolic BP is <55 mm Hg (non-diabetics) or <70 mm Hg (diabetics).
- Transcutaneous oximetry (TcO2) can assess peripheral arterial insufficiency, with levels <40 mm Hg predictive of poor healing and <20 mm Hg consistent with critical limb ischemia.
- Angiography provides details on the location and extent of arterial stenoses or occlusion.
Medical Therapy for PAD (continued)
- Annual influenza vaccination is recommended for patients with PAD.
- Structured exercise programs, either supervised or community/home-based, are beneficial for patients with PAD.
Exercise Programs
- Supervised exercise programs involve intermittent walking exercise under healthcare provider supervision.
- Structured community- or home-based exercise programs are self-directed with guidance from healthcare providers.
