Atherosclerosis vs. Thrombosis — What's the Difference?
By Tayyaba Rehman & Fiza Rafique — Updated on May 7, 2024
Atherosclerosis involves the buildup of fats and cholesterol in artery walls, potentially narrowing them, while thrombosis refers to the formation of a clots inside a blood vessel.

Key Differences
Atherosclerosis often develops gradually over many years and can be asymptomatic until an artery is significantly narrowed or blocked. In contrast, thrombosis can occur suddenly and symptoms might appear abruptly depending on the location and severity of the clot.
Risk factors for atherosclerosis include high cholesterol, hypertension, smoking, diabetes, and an unhealthy diet. Conversely, thrombosis risk factors also include prolonged immobility, certain genetic conditions, pregnancy, and use of hormone therapy or birth control pills.
Treatment for atherosclerosis typically involves lifestyle changes, medications to lower cholesterol, and sometimes surgical procedures like angioplasty. On the other hand, thrombosis is treated with anticoagulants to prevent clot growth, thrombolytic agents to dissolve clots, and sometimes surgical intervention to remove the clot.

Compare with Definitions
Atherosclerosis
Commonly affects the heart's coronary arteries.
Atherosclerosis of coronary arteries is a leading cause of heart disease.
Thrombosis
Treated with thinners.
He was prescribed warfarin for his thrombosis.
Atherosclerosis
Can lead to reduced oxygenation.
Severe atherosclerosis can result in angina or heart attacks.
Thrombosis
Risk increases with certain conditions.
Cancer patients have a higher risk of thrombosis.
Atherosclerosis
Chronic disease involving arterial wall thickening from fat accumulation.
Diets high in saturated fats can accelerate atherosclerosis.
Thrombosis
Can occur in arteries or veins.
Venous thrombosis is common in inactive patients.
Atherosclerosis
Often associated with lifestyle factors.
Smoking is known to exacerbate atherosclerosis.
Thrombosis
May cause sudden symptoms.
Thrombosis in the brain can lead to immediate stroke symptoms.
Atherosclerosis
Detected via imaging like angiography.
Angiography revealed atherosclerosis in his major arteries.
Atherosclerosis
Atherosclerosis is a pattern of the disease arteriosclerosis in which the wall of the artery develops abnormalities, called lesions. These lesions may lead to narrowing due to the buildup of atheromatous plaque.
Atherosclerosis
A stage of arteriosclerosis involving fatty deposits (atheromas) inside the arterial walls
Common Curiosities
What is atherosclerosis?
Atherosclerosis is the buildup of fats, cholesterol, and other substances in and on the artery walls.
What are common treatments for thrombosis?
Treatments include anticoagulants, thrombolytic therapy, and sometimes surgery.
What symptoms might suggest atherosclerosis?
Symptoms may include chest pain, shortness of breath, or extreme fatigue.
What are the dangers of untreated atherosclerosis?
It can lead to critical conditions like heart attacks, strokes, and peripheral artery disease.
Can lifestyle changes affect both conditions?
Yes, healthier lifestyle choices can help manage both atherosclerosis and reduce the risk of thrombosis.
Are there any preventive measures for atherosclerosis?
Yes, maintaining a healthy diet, regular exercise, and avoiding smoking.
Can thrombosis lead to other health issues?
Yes, it can lead to complications like pulmonary embolism or stroke.
How quickly can thrombosis develop?
Thrombosis can develop very quickly, particularly in conditions that increase clotting risk.
What is the difference between arterial and venous thrombosis?
Arterial thrombosis occurs in arteries, often causing acute symptoms, while venous thrombosis occurs in veins, usually leading to swelling and pain.
How are these conditions diagnosed?
Through clinical evaluation, imaging, and sometimes laboratory tests specific to each condition.
Can both conditions be fatal?
Yes, both can lead to potentially fatal events like heart attacks or strokes.
