Study Notes
Effects of Aging on Peripheral Vascular Disease
- Peripheral vascular disease (PVD) encompasses abnormalities in blood vessels outside the heart and lymphatics.
- Age-related degenerative changes in blood vessel walls affect nutrient and blood transport to tissues.
- Inner (tunica interna) walls thicken and become less flexible, while middle (tunica media) walls lose elasticity.
- Reduced elasticity and flexibility lead to increased peripheral vascular resistance, elevated blood pressure, and heightened PVD susceptibility.
Risk Factors for Peripheral Vascular Disease
-
Non-modifiable Risk Factors:
- Age increases vascular resistance due to arteriosclerotic changes, reducing blood flow.
- Gender plays a role; men are more affected prior to menopause, after which women’s risk increases.
- Family history of atherosclerosis raises individual risk levels.
-
Modifiable Risk Factors:
- Smoking leads to vasoconstriction, elevated blood pressure, and diminished circulation to extremities.
- Hypertension causes vessel wear and tear, creating fibrous tissue and narrowing the lumen.
- Hyperlipidemia contributes to plaque formation; dietary changes and medication may be necessary.
- Obesity increases workload on the heart and blood vessels, complicating venous congestion.
- Sedentary lifestyle hampers muscle tone and blood return to the heart.
- Emotional stress affects blood pressure and cholesterol levels.
- Diabetes mellitus exacerbates atherosclerosis via uncontrolled glucose levels.
Signs and Symptoms of Peripheral Vascular Disorders
-
Arterial Assessment Findings:
- Ischemic pain (intermittent claudication) arises during activities due to insufficient oxygen supply, alleviated by rest.
- Weak, thready, or absent pulses are signs of inadequate blood flow, with prolonged capillary refill times.
- Dry, shiny, hairless skin on the extremities, which may feel cool or cold.
- Limb pallor when elevated and redness when dangling.
-
Venous Assessment Findings:
- Pain associated with venous disorders is often alleviated by activity or elevation.
- Peripheral pulses are generally present despite venous insufficiency.
- Edema occurs due to inadequate venous return, with a comparison necessary against unaffected limbs.
- Changes in skin pigmentation may occur, leading to complications like stasis ulcers.
Assessment Tools for Peripheral Vascular Disorders
- Use "The Five P's" for arterial occlusion: Pain, Pallor, Pulselessness, Paresthesia, Paralysis.
- The mnemonic "PATCHES" assists in determining if the condition is arterial or venous: Pulses, Appearance, Temperature, Capillary refill, History, Edema, Symptoms.
Hypertension Classification and Characteristics
-
Stages of Hypertension:
- Stage I: Systolic 140-159 mmHg or diastolic 90-99 mmHg.
- Stage II: Systolic ≥160 mmHg or diastolic ≥100 mmHg.
- Hypertensive crisis: Requires immediate care; systolic >180 mmHg or diastolic >110 mmHg.
-
Diagnosis of Hypertension:
- Requires averages of two or more elevated readings on separate occasions.
Etiology and Pathophysiology of Hypertension
- Blood pressure is influenced by blood flow (heart output) and peripheral vascular resistance (vessel diameter and blood viscosity).
- Increased peripheral vascular resistance results from vessel narrowing and vasoconstriction.
- Key physiological controls include the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS), affecting blood volume and vessel constriction.
Types of Hypertension
-
Essential Hypertension:
- Cause is often unknown; accounts for 90-95% of cases, with various risk factors.
-
Secondary Hypertension:
- Results from identifiable health conditions, often resolves when the underlying issue is treated.
-
Malignant Hypertension:
- Rapidly progressing, severe condition with diastolic pressures >120 mmHg, damaging organs if untreated.
Clinical Manifestations of Hypertension
- Often asymptomatic until significant organ damage occurs.
- Potential symptoms include morning headaches and blurred vision.
- Chronic hypertension can lead to target organ complications such as heart, brain, kidney, and eye damage.
Assessment and Diagnosis of Hypertension
- Includes obtaining subjective and objective data, as well as diagnostic tests to evaluate organ functions.
- Goal: Maintain blood pressure below 140/90 mmHg using lifestyle and pharmacological interventions.
Patient Teaching for Hypertension Management
- Encourage weight loss, regular exercise, reduced saturated fat, limited alcohol intake, and lower sodium consumption.
- Smoking cessation is crucial for effective management.
- Implement relaxation techniques to manage stress and overall blood pressure.
- Pharmacologic therapy may include diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers to assist in control.### Hypertension Management
- Regular exercise (30-45 minutes, 3-4 times per week) aids in weight loss and limits alcohol consumption.
- For African American females with primary hypertension taking Lisinopril, switch to Cardizem (a calcium channel blocker) and add a diuretic due to better outcomes with this combination.
- Antihypertensives include ACE inhibitors, diuretics, calcium channel blockers, beta blockers, angiotensin II receptor blockers, and alpha-agonists.
- Systolic blood pressure indicates the peak pressure during heart contraction, while diastolic pressure indicates relaxation between beats.
Peripheral Vascular Resistance
- Peripheral vascular resistance is influenced by the diameter of blood vessels and blood viscosity.
- The body regulates vasoconstriction and vasodilation primarily through the sympathetic nervous system and the renin-angiotensin system (RAAS).
- Blood flow and peripheral vascular resistance are crucial for blood pressure regulation.
Arterial Disorders
- Arteriosclerosis vs. Atherosclerosis: Arteriosclerosis involves thickened, inelastic arterial walls; atherosclerosis involves plaque buildup, narrowing arteries, leading to ischemia and potential necrosis.
- Buerger’s Disease: Affects small and medium-sized arteries in smokers, leading to ischemia and often necessitating amputation.
- Raynaud’s Disease: Characterized by spasms causing intermittent ischemia, notably in fingers and toes, often exacerbated by cold or stress.
Aneurysms
- Aneurysms are dilated portions of arteries, most common in the aorta, with risk factors including hypertension, family history, and smoking.
- Symptoms may include a pulsating mass, chest pain, and severe pain if rupture occurs, requiring immediate surgical intervention.
Arterial Embolism
- Arterial emboli can originate from clots or plaque, causing acute ischemia and severe symptoms.
- Medical management includes anticoagulants, fibrinolytics, and potential surgical procedures like endarterectomy or embolectomy.
Nursing Interventions for Peripheral Venous Disease
- Focus on enhancing blood flow: encourage changing positions, using compression stockings, and frequent circulation checks.
- Patient education emphasizes avoiding prolonged inactivity, using leg elevation to improve venous return, and wearing well-fitting shoes.
Risk Factor Management
- Tobacco use is strongly linked to Buerger’s disease; smoking cessation is critical.
- Regular exercise, leg elevation, and compression stockings help prevent thrombus formation and improve peripheral circulation.
Assessment and Diagnostic Testing
- For conditions like arterial occlusions, subjective data such as pain during activity, alongside objective measures like pulse strength and skin assessment, are crucial.
- Diagnostic tests include Doppler ultrasound, angiography, MRI, and treadmill tests to evaluate blood flow and complications.
Medical Management
- Management strategies target prevention of occlusions with lifestyle changes (like smoking cessation), anticoagulants, and surgical interventions for advanced cases.
- Importance of monitoring for signs of ischemia and other complications post-surgery, such as changes in skin color, sensation, and movement.### Patient Education on Arterial Embolism
