Summary
Atherosclerosis, a leading cause of death, is now understood as an inflammatory process. Research is shifting focus from hypercholesterolemia to the arterial wall's inflammatory response.
Area of Science:
- Cardiovascular Science
- Immunology
- Pathophysiology
Context:
- Atherosclerosis is a primary cause of mortality in developed nations.
- Historically, hypercholesterolemia research dominated atherosclerosis studies.
- Recent findings link atherosclerosis to normolipidemic subjects, dysmetabolic features, and infections.
Purpose:
- To re-evaluate the pathophysiological archetypes of atherosclerosis.
- To incorporate atherosclerosis into the classification of inflammatory processes.
- To highlight the inflammatory response in arterial wall aggression as a key research area.
Summary:
- The understanding of atherosclerosis has evolved significantly.
- While hypercholesterolemia was once the central focus, current research acknowledges its occurrence in normolipidemic individuals.
- Emerging evidence implicates dysmetabolic features and infectious agents, leading to its reclassification as an inflammatory condition.
Impact:
- This paradigm shift redefines atherosclerosis research and laboratory follow-up.
- It emphasizes the inflammatory response to arterial wall injury as a critical area for investigation.
- The new perspective offers novel avenues for understanding and potentially treating atherosclerosis.
