Blood Clots and Heart Attacks Can Happen
Cholesterol can become dangerous when it contributes to plaque buildup inside artery walls. This process is called atherosclerosis. Plaque can narrow arteries and reduce blood flow. Sometimes plaque can burst, leading to a blood clot. If the clot blocks blood flow to the heart, it can cause a heart attack. If it blocks blood flow to the brain, it can cause a stroke. Mayo Clinic explains that plaque can burst and lead to a blood clot, and that atherosclerosis can cause heart attack
