How can you tell if a plaque is vulnerable?
Vulnerable plaques can be clinically identified by intracoronary imaging modalities such as intravascular ultrasonography (IVUS) or optical coherence tomography (OCT) and are known to have the imaging features of thin-cap fibroatheromas (TCFAs).
Which biomarker is associated with rupture prone plaque?
This review aims at giving an overview on recent biomarker candidates that are related to destabilization and rupture of the atherosclerotic plaque. C-reactive protein (CRP) is a member of the pentraxin family and represents the most extensively studied proinflammatory molecule.
How are vulnerable plaques treated?
Local treatment of vulnerable plaques by percutaneous coronary intervention and systemic treatment with anti-inflammatory and low-density lipoprotein–lowering drugs are currently being investigated in large randomized clinical trials to assess their therapeutic potential for reducing adverse coronary events.
What causes rupture of vulnerable plaque?
The combination of increased mechanical stress on the fibrous cap and weakening of the fibrous cap extracellular matrix leads to plaque rupture. A cascade of events leads to plaque rupture. Accumulation of lipid in the lesion leads to dramatically increased stress on the fibrous cap of the lesion.
Can plaque be reabsorbed?
Furthermore, concomitant reductions in plaque size and cholesterol levels have been documented in experimental studies without changes in collagen content. Therefore, plaque size reduction is likely to occur in response to reabsorption of lipids from the atherosclerotic plaque.
What causes plaque to break off?
Like magma underneath a volcano, rumblings in the core of a deposit, which contains dead cells, can break open the plaques. Once the plaque ruptures, a blood clot in the lumen of the artery can form.
What happens to the contents of a ruptured plaque?
Plaque rupture results in circulatory exposure of its thrombogenic contents (e.g., tissue factor, collagens, and lipids) leading to thrombus formation and MI [312,313].
What does stent placement involve?
To put a stent in, your doctor makes a small cut in a blood vessel in your groin, arm, or neck. They then thread a thin tube called a catheter through the blood vessel to the blocked artery. The tube has a tiny balloon at the end of it. Your doctor inflates the balloon inside your blocked artery.
Do statins clear the arteries of plaque 2020?
A: Yes. There have been several clinical studies — many of them done here at Cleveland Clinic — that show statins can reverse plaque buildup. Two statins in particular, atorvastatin, which is sold under the brand name Lipitor, and rosuvastatin, which is sold under the brand name Crestor, are the strongest statins.
