In 2022, research into —the fatty plaque buildup in artery walls—shifted from viewing it as simple "clogging" to understanding it as a complex, dynamic biological process. The Silent Architect

: To contain this mess, the body builds a fibrous cap over the fatty core. As long as this cap remains stable, the atheroma may grow silently for decades without causing symptoms. 2022 Breakthroughs: New Perspectives

: Medical discussions in 2022 increasingly moved away from focusing solely on ischemia (reduced blood flow) to focusing on the atheroma itself . The danger isn't just a narrow artery; it's a "vulnerable" plaque that might rupture. The Danger of the "Burst"

The story of an atheroma begins early, often in one's teens or 20s. It starts with microscopic damage to the , the thin inner lining of the artery. Once this barrier is breached, cholesterol (LDL) and other fats begin to seep into the artery wall.

Recent archives and studies have highlighted two major shifts in how we understand these plaques:

: Researchers from the NIH discovered that smooth muscle cells within atheromas can behave like tumor cells—mutating and multiplying rapidly. This discovery opened the door to using anti-cancer drugs, like niraparib , which successfully shrank plaques in early lab trials.
