Insights
Inflammation drives atherosclerosis, a leading cause of death. This review details how inflammatory leukocytes promote disease progression and destabilization, leading to acute coronary syndromes like myocardial infarction.
Area of Science:
- Cardiovascular Medicine
- Immunology
- Pathology
Background:
- Atherosclerosis is a chronic inflammatory vascular disease and a leading global cause of mortality.
- Acute coronary syndromes (ACS), including myocardial infarction and unstable angina, are severe complications of atherosclerosis.
- Inflammation plays a critical role in the initiation, progression, and destabilization of atherosclerotic plaques.
Purpose of the Study:
- To review the pivotal role of inflammatory leukocytes in vascular inflammation.
- To elucidate how these leukocytes contribute to atherosclerotic disease progression.
- To explain the mechanisms by which leukocytes destabilize plaques, causing acute coronary syndromes.
Main Methods:
- Literature review focusing on inflammatory processes in atherosclerosis.
- Analysis of the cellular and molecular mechanisms of leukocyte involvement.
- Synthesis of current understanding regarding inflammation-driven plaque destabilization.
Main Results:
- Inflammatory leukocytes are central players in the pathogenesis of atherosclerosis.
- Leukocyte recruitment and activation promote plaque growth and complexity.
- Leukocyte-mediated processes are key drivers of atherosclerotic plaque rupture and thrombosis.
Conclusions:
- Targeting inflammatory leukocytes may offer therapeutic strategies for atherosclerosis.
- Understanding leukocyte function is crucial for preventing acute coronary syndromes.
- Inflammation is a critical therapeutic target in managing atherosclerotic cardiovascular disease.
Abstract:
Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis' most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.
