The body’s immune system can impact cardiovascular health in any number of ways. In some cases, cytokines cause inflammation that can weaken the heart and lead to fibrosis. In other cases,immune system activation can trigger blood clot formation,with potential thromboembolic effects. In cases of acute illness, immune system effects on the blood vessels can reduce blood pressure and put excess strain on the heart.

For these and other reasons,Cleveland Clinic’s Heart,Vascular and Thoracic Institute is elevating the role of cardioimmunology expertise in the care of appropriate patients through the creation of a cardioimmunology center led by a new staff physician,David Zidar, MD, PhD, an interventional cardiologist with PhD-level training in immunology.
In a recent episode of Cleveland clinic’s Cardiac Consult podcast,Dr.Zidar sits down with Cleveland Clinic Cardiovascular Medicine Chair Samir Kapadia, MD, to explore the intersection of immune pathways and cardiovascular disease. They address the following topics, among others:
* The immune system’s impact on the heart
* Connections between stress and automimmune diseases affecting the heart
* Clonal hematopoiesis and immune monitoring
* Integration of immunologic markers with electronic health data for early identification of at-risk patients
* The role of a cardioimmunology
Excerpt from the Podcast: Cardioimmunology and Predicting Heart Health
This excerpt from a podcast discussion between Dr. samir Kapadia and Dr. David Zidar focuses on the emerging field of cardioimmunology – the intersection of the immune system and cardiovascular health. They explore the potential of using immunological markers in the blood to predict heart disease risk and monitor the effectiveness of interventions.
key discussion Points:
* CHIP Mutations & Immunological Monitoring: Dr. Kapadia initiates the conversation by noting the study of CHIP (clonal hematopoiesis of indeterminate potential) mutations in peripheral blood. He questions whether similar immunological parameters can be studied to assess overall health and monitor responses to interventions.
* Clonal Hematopoiesis & Immune Cell Behavior: Dr. Zidar explains that in clonal hematopoiesis,aging can lead to certain immune cells (specifically monocytes) outcompeting others. These less-desirable cells can exhibit behaviors detrimental to the heart and blood vessels through known immunological pathways. Studying this specific population can provide insights applicable to broader cardiovascular health.
* Holistic Health Monitoring: Dr. Kapadia emphasizes the importance of a extensive approach to health, beyond traditional metrics like cholesterol and blood pressure. He argues that a well-regulated immune system is crucial for the body’s ability to fight off adverse events. He proposes identifying high-risk individuals through novel immunological pathways and systems.
* The Immune System as an Early Warning system: Dr. Zidar views the immune system as a “canary in the coal mine,” constantly surveying tissues. He believes that analyzing blood markers reflecting immune activity can help identify patients at highest risk before experiencing cardiovascular events. The increasing availability of electronic health records facilitates the discovery of at-risk patient populations.
* Cardioimmunology Center & Diagnostic Potential: Dr. Kapadia concludes by highlighting the potential of a dedicated cardioimmunology center to assist individuals with existing heart problems or those seeking to prevent them. It could also aid in diagnosing undiagnosed heart issues and understanding their connection to other health findings.
In essence, the conversation highlights a shift towards proactive cardiovascular care, leveraging the power of immunology to predict, prevent, and manage heart disease.
