Heart brain interactions

Description

Heart–brain interactions refer to the bidirectional relationship between cardiac and neurological systems, where dysfunction in one affects the other. Stroke, epilepsy, or brain injury can cause cardiac arrhythmias, neurogenic stunned myocardium, or Takotsubo cardiomyopathy. Conversely, heart failure, arrhythmias, or myocardial infarction may lead to cognitive decline, embolic stroke, or hypoxic brain injury. Mechanisms involve the autonomic nervous system, inflammation, and neurohormonal pathways. Understanding these interactions is crucial in critical care, cardiology, and neurology for holistic management.
