Insights
Cardiac arrhythmias like atrial fibrillation can cause serious health issues. This review explores biological markers, focusing on neurohormonal, inflammatory, and metabolic pathways, to predict arrhythmia onset and complications.
Area of Science:
- Cardiology
- Biomedical Research
- Translational Medicine
Background:
- Cardiac arrhythmias, including atrial fibrillation and ventricular tachycardia, are significant contributors to cardiovascular morbidity and mortality.
- These arrhythmias can arise from underlying structural heart disease or manifest as primary indicators of subclinical cardiovascular disease.
- Consequences of cardiac arrhythmias include stroke, heart failure, and increased mortality.
Purpose of the Study:
- To review clinical and translational studies identifying biological markers for predicting cardiac arrhythmias.
- To highlight mechanisms involving the neurohormonal system, inflammation, the renin-angiotensin-aldosterone system, and metabolic pathways.
- To inform risk stratification and diagnostic strategies for early intervention.
Main Methods:
- Literature review of clinical and translational studies.
- Focus on research identifying predictive biological markers for cardiac arrhythmias.
- Analysis of mechanisms including neurohormonal, inflammatory, and metabolic pathways.
Main Results:
- Identification of potential biological markers for predicting cardiac arrhythmia onset.
- Emphasis on the role of the neurohormonal system, inflammation, RAAS, and metabolic pathways.
- Insights into mechanisms underlying arrhythmia development and complications.
Conclusions:
- Biological markers hold promise for predicting cardiac arrhythmias and their complications.
- Understanding neurohormonal, inflammatory, and metabolic pathways is crucial for risk stratification.
- Early identification and intervention based on these markers can mitigate adverse cardiovascular events.
Abstract:
Cardiac arrhythmias including atrial fibrillation, ventricular tachycardia, and ventricular fibrillation are important causes of cardiovascular morbidity and mortality. Although they usually occur in the setting of structural heart disease, these arrhythmias can be the primary manifestation of subclinical cardiovascular disease and have deleterious consequences including stroke, heart failure, and death. Investigational efforts have focused on developing risk stratification algorithms and diagnostic methods to identify patients who are most likely to sustain cardiac arrhythmias and benefit from early pharmacologic and interventional therapies. This review highlights important clinical and translational studies that identify potential biological markers to predict the onset of cardiac arrhythmias and their complications. Particular focus is placed on mechanisms involving the neurohormonal system, inflammation, the renin-angiotensin-aldosterone system, and metabolic pathways.
