Atherosclerosis is a hardening and narrowing of your arteries caused by cholesterol plaques lining the artery over time. It can put blood flow at risk as your arteries become blocked.
Atherosclerosis begins with damage to the endothelium. Common causes include:
High blood pressure
Inflammation, like from arthritis or lupus
Obesity or diabetes
Symptoms related to your coronary arteries
Arrhythmia, an unusual heartbeat
Pain or pressure in your upper body, including your chest, arms, neck, or jaw. This is known as angina.
Shortness of breath
Symptoms related to the arteries that deliver blood to your brain
Numbness or weakness in your arms or legs
A hard time speaking or understanding someone who’s talking
Drooping facial muscles
Trouble seeing in one or both eyes
Symptoms related to the arteries of your arms, legs, and pelvis
Leg pain when walking
High alcohol intake (more than one drink for women, one or two drinks for men, per day)
High blood pressure
Not eating fruits and vegetables
Not exercising regularly
Angiogram, in which your doctor puts dye into your arteries so they’ll be visible on an X-ray
Ankle-brachial index, a test to compare blood pressures in your lower leg and arm
Blood tests to look for things that raise your risk of having atherosclerosis, like high cholesterol or blood sugar
CT scan or magnetic resonance angiography (MRA) to look for hardened or narrowed arteries
EKG, a record of your heart’s electrical activity
Stress test, in which you exercise while health care professionals watch your heart rate, blood pressure, and breathing
Drugs for high cholesterol and high blood pressure will slow and may even halt atherosclerosis. They lower your risk of heart attack and stroke.
Your doctor can use more invasive techniques to open blockages from atherosclerosis or go around them:
Angiography and stenting
Your doctor puts a thin tube into an artery in your leg or arm to get to diseased arteries. Blockages are visible on a live X-ray screen. Angioplasty (using a catheter with a balloon tip) and stenting can often open a blocked artery. Stenting helps ease symptoms, but it does not prevent heart attacks.
Your doctor takes a healthy blood vessel, often from your leg or chest, and uses it to go around a blocked segment.
Your doctor goes into the arteries in your neck to remove plaque and restore blood flow. They also may place a stent higher risk patients.
A drug dissolves a blood clot that’s blocking your artery.⌖ diseases treatments atherosclerosis disorders health prevention cardiovascular-system
