Insights
Inflammation
Area of Science:
- Integrative biology
- Cardiovascular research
- Inflammatory signaling
Background:
- Traditional view of ischemic heart disease focuses on arterial plaques.
- Emerging research highlights the role of inflammation in cardiovascular disease.
Purpose of the Study:
- To explore the integrative biology of inflammation in ischemic cardiovascular disease.
- To identify novel inflammatory signaling networks involved in the disease process.
Main Methods:
- Review of recent research and clinical data.
- Analysis of inflammatory signaling pathways.
- Integration of findings across multiple organ systems.
Main Results:
- Discovery of unsuspected inflammatory signaling networks.
- Identification of links between the brain, autonomic nervous system, bone marrow, spleen, atherosclerotic plaque, and myocardium.
- Clinical data confirms the relevance of these inflammatory networks.
Conclusions:
- Inflammatory networks play a crucial role in ischemic cardiovascular disease.
- The traditional cardiovascular continuum extends beyond the heart and vessels to include the nervous system, spleen, and bone marrow.
Abstract:
Physicians have traditionally viewed ischemic heart disease in a cardiocentric manner: plaques grow in arteries until they block blood flow, causing acute coronary and other ischemic syndromes. Recent research provides new insight into the integrative biology of inflammation as it contributes to ischemic cardiovascular disease. These results have revealed hitherto unsuspected inflammatory signaling networks at work in these disorders that link the brain, autonomic nervous system, bone marrow, and spleen to the atherosclerotic plaque and to the infarcting myocardium. A burgeoning clinical published data indicates that such inflammatory networks-far from a mere laboratory curiosity-operate in our patients and can influence aspects of ischemic cardiovascular disease that determine decisively clinical outcomes. These new findings enlarge the circle of the traditional "cardiovascular continuum" beyond the heart and vessels to include the nervous system, the spleen, and the bone marrow.
