Insights
Atrial fibrillation (AF) treatments require validated preclinical models. This review details various models, from cell cultures to organoids, to aid researchers in selecting the best approach for AF research.
Area of Science:
- Cardiovascular Research
- Biomedical Engineering
- Pharmacology
Background:
- Atrial fibrillation (AF) is a prevalent cardiac arrhythmia causing significant health issues like heart failure and stroke.
- Current treatments for AF involve pharmacological and non-pharmacological strategies.
- Effective therapeutic development necessitates reliable preclinical models to test and optimize interventions.
Purpose of the Study:
- To review and compare existing preclinical models for studying atrial fibrillation.
- To provide guidance on selecting appropriate models based on research objectives.
- To highlight the advantages, applications, and limitations of diverse AF models.
Main Methods:
- Comprehensive literature review of preclinical models for atrial fibrillation.
- Categorization of models including in vitro, traditional animal models, organoids, and organs-on-a-chip.
- Analysis of model-specific features, benefits, and drawbacks.
Main Results:
- A spectrum of preclinical models exists, each offering unique insights into AF pathophysiology.
- Traditional models like animal studies and cell cultures have established roles.
- Emerging technologies such as organoids and organs-on-a-chip offer advanced, human-relevant platforms.
Conclusions:
- The choice of preclinical model is critical for successful AF research and therapeutic validation.
- Each model type presents distinct advantages and limitations that must be considered.
- Selecting the right model ensures accurate assessment and optimization of AF treatments.
Abstract:
Atrial fibrillation is the most common type of cardiac arrhythmias in humans, mostly caused by hyper excitation of specific areas in the atrium resulting in dyssynchronous atrial contractions, leading to severe consequences such as heart failure and stroke. Current therapeutics aim to target this condition through both pharmacological and non-pharmacological approaches. To test and validate any of these treatments, an appropriate preclinical model must be carefully chosen to refine and optimise the therapy features to correctly reverse this condition. A broad range of preclinical models have been developed over the years, with specific features and advantages to closely mimic the pathophysiology of atrial fibrillation. In this review, currently available models are described, from traditional animal models and in vitro cell cultures to state-of-the-art organoids and organs-on-a-chip. The advantages, applications and limitations of each model are discussed, providing the information to select the appropriate model for each research application.
