Atherosclerosis and Varicose Veins
Atherosclerosis and varicose veins both involve the circulatory system, yet they affect different types of blood vessels and arise through different mechanisms. Atherosclerosis develops within arteries, the vessels that carry oxygen-rich blood away from the heart. Varicose veins affect the veins that return blood to the heart at lower pressure.
In the UK, cardiovascular disease remains one of the leading causes of death, and atherosclerosis underlies most cases of heart attack and stroke. Varicose veins are also common, affecting up to one in three adults, particularly in the lower legs. Although these conditions are separate, they share several risk factors, including age, smoking, excess weight and inactivity.
A clear distinction between arterial and venous disease helps ensure accurate diagnosis and appropriate treatment.
Atherosclerosis
Atherosclerosis is the gradual narrowing and stiffening of arteries caused by the buildup of plaque within the arterial wall. Plaque is composed of cholesterol, inflammatory cells, calcium and fibrous tissue.
The condition usually progresses slowly over many years. Early plaques may remain stable, causing only limited narrowing. More advanced plaques can become unstable. If the surface of a plaque ruptures, a blood clot can form rapidly and block the artery. This sudden blockage is responsible for most heart attacks and many strokes.
Atherosclerosis may affect the coronary arteries of the heart, the carotid arteries in the neck, the renal arteries supplying the kidneys and the peripheral arteries of the legs.
Risk Factors and Cardiovascular Assessment
Age increases risk, particularly in men over 45 and women over 55. However, lifestyle and metabolic factors have a major influence.
Smoking damages the inner lining of the arteries and accelerates plaque formation. High blood pressure increases mechanical stress on artery walls. Raised low-density lipoprotein cholesterol promotes fatty deposit formation. Diabetes further increases risk, especially where blood glucose control is poor.
In UK primary care, cardiovascular risk is often estimated using the QRISK scoring system, which calculates the likelihood of a heart attack or stroke within the next ten years. Blood pressure targets and cholesterol levels are guided by national recommendations, with statin therapy commonly advised in patients with elevated risk.
Dietary advice in line with NHS guidance includes limiting salt intake to no more than 6 grams per day, reducing saturated fat and choosing unsaturated fats such as olive oil, nuts and oily fish. Adults are advised to complete at least 150 minutes of moderate physical activity per week.
Raised C reactive protein levels may reflect arterial inflammation and are associated with increased cardiovascular risk. Sleep apnoea, excess alcohol intake and psychological stress also contribute.
Symptoms and Disease Progression
Atherosclerosis often produces no symptoms in its early stages. Symptoms usually appear once significant narrowing of the blood vessels restricts blood flow or a clot forms.
In coronary artery disease, patients may experience chest tightness or pressure, particularly during exertion. In peripheral arterial disease, calf pain during walking that improves with rest is known as intermittent claudication. More advanced disease may cause rest pain in the foot, non-healing wounds or tissue damage, known as critical limb ischaemia.
If carotid arteries are affected, symptoms may include transient weakness, facial drooping or speech disturbance, which may signal a transient ischaemic attack or stroke and require urgent medical attention.
Diagnosis and Investigation
Clinical examination may reveal reduced pulses, bruits over arteries or signs of poor circulation in the legs.
Blood tests assess cholesterol and glucose levels. An electrocardiogram and echocardiogram assess cardiac function. In peripheral arterial disease, an ankle-brachial pressure index compares blood pressure in the ankle and arm to identify reduced blood flow.
Imaging may include Doppler ultrasound, CT angiography or MR angiography to visualise arterial narrowing. Coronary angiography remains the gold standard for assessing coronary artery disease in selected patients.
Treatment and Risk Reduction
Management focuses on reducing future cardiovascular events and slowing disease progression.
Lifestyle measures are central. Smoking cessation has immediate benefits. Regular physical activity improves circulation and cardiovascular fitness. A Mediterranean-style dietary pattern rich in vegetables, fruit, whole grains, legumes and oily fish supports heart health.
Medications are frequently required. Statins lower cholesterol and stabilise plaque. Antiplatelet therapy may reduce the risk of clot formation in appropriate patients. Blood pressure-lowering medications, including ACE inhibitors and calcium channel blockers, reduce strain on artery walls.
In more advanced cases, interventional procedures such as angioplasty with stent placement or coronary artery bypass graft surgery may be recommended.
Varicose Veins
Varicose veins develop within the superficial venous system of the legs. They appear enlarged, twisted, and often blue or purple. Veins contain one-way valves that prevent blood from flowing backwards. If these valves fail, blood pools in the vein, leading to stretching and visible enlargement.
Venous reflux, where blood flows in the wrong direction due to valve failure, is the underlying mechanism. The superficial and deep venous systems are connected, and proper assessment ensures that the deep system remains functioning before any treatment is considered.
Varicose veins affect around 30 per cent of adults in the UK. Women are more frequently affected, partly due to hormonal influences and pregnancy.
Contributing Factors
Increasing age weakens the walls and valves of the veins. Pregnancy increases pelvic venous pressure. Occupations involving prolonged standing may worsen symptoms. Excess body weight increases venous pressure in the legs. A family history of venous disease also increases risk.
Symptoms and Complications
Symptoms often include aching, heaviness and swelling, particularly after standing. Some patients notice itching or burning over the affected veins.
Chronic venous insufficiency may develop if reflux persists. The skin around the ankle may become discoloured or inflamed, a condition known as venous eczema. Lipodermatosclerosis, a hardening of the skin and underlying tissue, may occur in long-standing disease. Venous leg ulcers can develop near the ankle and may be slow to heal.
Superficial thrombophlebitis involves inflammation and clot formation within a superficial vein. Bleeding from a varicose vein can occur if the skin becomes fragile.
Diagnosis and Treatment Approaches
Assessment involves clinical examination and duplex ultrasound scanning. Ultrasound maps venous reflux and confirms the patency of the deep venous system. It also excludes deep vein thrombosis, which requires different management.
Conservative measures may help reduce symptoms. Graduated compression stockings support venous return. Regular walking activates the calf muscle pump. Weight control reduces pressure within leg veins. Elevating the legs during rest may ease swelling.
For symptomatic veins or complications, minimally invasive procedures are widely used in the UK. Endovenous laser therapy and radiofrequency ablation seal the faulty vein using heat. Ultrasound-guided foam sclerotherapy involves injecting a solution that causes the vein to close. Cyanoacrylate glue closure seals the vein without the need for thermal energy.
Traditional surgical ligation and stripping are less common but may still be appropriate in selected cases.
Arterial and Venous Disease In The Legs
Peripheral arterial disease and chronic venous insufficiency may coexist, particularly in older adults.
It is important to assess arterial circulation before prescribing compression stockings. In patients with significant arterial disease, compression may not be appropriate. Duplex ultrasound and ankle brachial pressure index testing help ensure safe treatment planning.
