Insights
The heart and brain are intricately linked. This review explores how stroke and heart disease impact each other, highlighting the complex heart-brain axis interactions.
Area of Science:
- Cardiology
- Neurology
- Neuroscience
Background:
- The heart and brain are interconnected via nervous and humoral pathways, maintaining homeostasis under normal conditions.
- Pathological conditions in one organ significantly affect the other, impacting patient prognosis.
- The heart-brain axis plays a crucial role in overall health, with disruptions leading to severe consequences.
Purpose of the Study:
- To review the pathological interactions within the heart-brain axis.
- To explore these interactions in the context of stroke, ischemic heart disease, heart failure, and atrial fibrillation.
- To summarize current evidence on the bidirectional communication between the heart and brain.
Main Methods:
- Literature review of existing evidence on heart-brain axis interactions.
- Analysis of pathological mechanisms linking cardiovascular and cerebrovascular diseases.
- Synthesis of findings related to stroke-heart syndrome and cardiac conditions affecting the brain.
Main Results:
- Stroke-heart syndrome involves cardiovascular complications like myocardial injury, arrhythmias, and heart failure following ischemic stroke.
- Brain damage triggers cardiac injury through neuroinflammation, immune activation, and sympathetic-immune interactions.
- Cardiac conditions such as myocardial ischemia, heart failure, and atrial fibrillation increase stroke and cognitive decline risk.
Conclusions:
- The heart-brain axis is a critical determinant of health, with bidirectional pathological crosstalk.
- Understanding these interactions is vital for managing stroke, heart disease, and related neurological conditions.
- Further research into the heart-brain axis mechanisms can lead to improved therapeutic strategies.
Abstract:
The heart and brain are anatomically and functionally interconnected through nervous and humoral feedback mechanisms. Under physiological conditions, the heart-brain axis helps maintain cardiovascular and cerebral homeostasis. Pathology affecting one organ can profoundly impact the other, significantly worsening prognosis. The term stroke-heart syndrome refers to cardiovascular complications following acute ischemic stroke, including myocardial injury, infarction, ventricular dysfunction, arrhythmias (e.g., atrial fibrillation), heart failure, takotsubo syndrome, and sudden cardiac death. Brain damage-induced cardiac injury arises from a complex interplay of neuroinflammation, systemic immune activation, sympathetic-immune interactions, catecholamine toxicity, endothelial dysfunction, and gut-brain-heart axis involvement. Conversely, cardiac conditions, including myocardial ischemia, heart failure, and atrial fibrillation, are associated with an increased risk of stroke and cognitive decline. Myocardial ischemia can initiate systemic inflammation and neuroinflammation through sympathetic overdrive and platelet activation. Heart failure causes cerebral hypoperfusion and high thromboembolic risk, and atrial fibrillation promotes thrombus formation due to blood stasis. Atrial dysfunction and prothrombotic states may also occur independently of arrhythmia. This review summarises current evidence on the pathological interactions within the heart-brain axis, in the context of stroke, mental stress, ischemic heart disease, heart failure, and atrial fibrillation.
