Plaque ruptures in arteries when the plaque's fibrous cap weakens due to inflammation, high mechanical stress from blood flow, and breakdown of the underlying basement membrane, exposing its thrombogenic core and triggering a blood clot (thrombus) that can block the artery, leading to heart attack or stroke. Key factors include inflammatory cells (macrophages) degrading the cap, plaque geometry, high pressure, cholesterol accumulation, and microcalcifications.
Can you unclog your arteries, or reduce plaque buildup?
If atherosclerosis is in the arteries leading to your brain, you may feel symptoms of atherosclerosis that are similar to stroke, such as a sudden numbness or weakness in your arms or legs; difficulty speaking or slurred speech; sudden changes in eyesight, dizziness, sudden and severe headache; or drooping muscles in ...
As statins "melt" or reduce the soft, dangerous plaque, what's left behind often calcifies, forming a more stable “scar.” This calcified plaque is less likely to rupture—making it much safer from a clinical standpoint.
If there's too much cholesterol in the blood, the cholesterol and other substances may form deposits called plaque. Plaque can cause an artery to become narrowed or blocked. If a plaque ruptures, a blood clot can form.
The new study found, however, that rupture was significantly related to the depletion of proteins in the basement membrane, a thin layer that surrounds cells that cover the plaque. Loss of these cells weakens the plaque structure and leads to rupture.
Top Foods Cardiologists Want You to Avoid for Heart Health
Atorvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
For most people, atorvastatin stays in the body for about 3 days after stopping it. This timeframe is based on its half-life, which is about 14 hours. That said, atorvastatin is broken down into other active substances in the body that stay in your system for almost a week after your last dose.
Other signs you may have atherosclerosis (blocked arteries)
In addition to chest pain, symptoms of a clogged artery may include: Dizziness. Feeling like your heart is racing (heart palpitations) Nausea.
If plaque narrows those arteries, your kidneys can't get enough blood to work properly. This leads to a range of symptoms like fatigue, edema and itchy skin. Reduced blood flow to your kidneys can also raise your blood pressure.
When your heart pumps faster during aerobic exercise, it pushes more blood through the arteries. This keeps the arteries wider and more flexible, reducing blood pressure and making arteries less likely to collect plaque. Examples of aerobic exercise include walking, running, dancing, rowing, and swimming.
Plaque rupture occurs where the cap is thinnest and most infiltrated by foam cells (macrophages). In eccentric plaques, the weakest spot is often the cap margin or shoulder region,86 and only extremely thin fibrous caps are at risk of rupturing.
Symptoms of Calcium Build-Up
In advanced cases, atherosclerotic narrowing becomes so severe that the blood flow cannot meet the resting metabolic demands of the lower extremity. This results in ischemic rest pain, which is pain in the forefoot or toes when the legs are elevated or the patient is lying flat.
Liver damage
Sometimes, statin use could cause an increase in the level of enzymes in the liver. These enzymes signal inflammation. If the increase is only mild, you can continue to take the statin.
You can choose to take it at any time, as long as you stick to the same time every day. This prevents your blood levels from becoming too high or too low. Sometimes doctors may recommend taking it in the evening. This is because your body makes most cholesterol at night.
Statins have proven their potential to reduce end-point outcomes, such as death from cardiovascular disease.

In the groups receiving high-dose vitamin K1 or K2 (MK-4), not only was there no further arterial calcium accumulation, there was a 37% reduction of previously accumulated arterial calcification after six weeks. After 12 weeks, there was a 53% reduction in accumulated arterial calcium deposits.
The Worst Foods for Your Heart: What Cardiologists Warn Against
Do cardiologists recommend eating blueberries? Yes, many cardiologists suggest eating blueberries. They are good for your heart because of their antioxidants and fiber.
“Smoking is one of the most harmful things people can do to themselves,” Dr. Maniar says. Blood flow drops, slashing oxygen that fuels the heart, which compensates by spiking blood pressure, heart rate and rhythm, and can lead to hardened and narrowed arteries and blood clots causing cardiovascular disease.
