Baroreflex Function in Cardiovascular Disease.
Review
Overview
abstract
The baroreflex system is involved in modulating several physiological functions of the cardiovascular system and can directly and indirectly modulate cardiac output, blood pressure, and cardiac electrophysiology. In addition, it is involved in regulating neurohormonal pathways involved in the cardiovascular function, such as the renin-angiotensin-aldosterone system (RAAS) and vasopressin release. Baroreflex dysfunction is characterized by sympathetic overactivation and parasympathetic withdrawal and is associated with several cardiovascular diseases, such as hypertension, heart failure (HF), and coronary artery disease (CAD). Targeting the baroreflex system via invasive (e.g., baroreflex activation therapy and endovascular baroreceptor amplification) and non-invasive approaches (e.g., slow breathing exercises and exercise training) has emerged as a novel pathway to manage cardiovascular diseases. Studies examining the long-term safety and efficacy of such interventions in various cardiovascular diseases are needed.
