Insights
Atrial fibrillation increases stroke risk. Research is needed to improve stroke prevention strategies, including better risk assessment and optimized use of anticoagulants and left atrial appendage occlusion.
Area of Science:
- Cardiology
- Neurology
- Public Health
Background:
- Atrial fibrillation (AF) is a major risk factor for ischemic stroke, a leading cause of death and disability.
- The prevalence of AF and its risk factors is increasing due to an aging population and improved cardiovascular disease survival.
- Optimal stroke prevention strategies in AF patients require further research despite existing therapies.
Purpose of the Study:
- To summarize key research opportunities for stroke prevention in atrial fibrillation (AF) identified during a National Heart, Lung, and Blood Institute virtual workshop.
- To highlight knowledge gaps and propose targeted research to advance stroke prevention in AF.
- To encourage innovative research for personalized and effective stroke prevention in AF patients.
Main Methods:
- A virtual workshop convened experts to discuss stroke prevention in AF.
- The workshop focused on identifying critical research needs and knowledge gaps.
- Discussions covered risk stratification, oral anticoagulants, and left atrial appendage occlusion.
Main Results:
- Identified key research areas: improving stroke and bleeding risk stratification tools.
- Highlighted challenges and research needs concerning oral anticoagulants.
- Emphasized the need to delineate optimal roles for percutaneous and surgical left atrial appendage occlusion.
Conclusions:
- Further research is crucial to optimize stroke prevention in the growing AF population.
- Advancing risk stratification and addressing challenges with anticoagulation are key priorities.
- Defining the precise roles of left atrial appendage occlusion strategies is essential for personalized care.
Abstract:
Atrial fibrillation (AF) is one of the strongest risk factors for ischemic stroke, which is a leading cause of disability and death. Given the aging population, increasing prevalence of AF risk factors, and improved survival in those with cardiovascular disease, the number of individuals affected by AF will continue increasing over time. While multiple proven stroke prevention therapies exist, important questions remain about the optimal approach to stroke prevention at the population and individual patient levels. Our report summarizes the National Heart, Lung, and Blood Institute virtual workshop focused on identifying key research opportunities related to stroke prevention in AF. The workshop reviewed major knowledge gaps and identified targeted research opportunities to advance stroke prevention in AF in the following areas: (1) improving risk stratification tools for stroke and intracranial hemorrhage; (2) addressing challenges with oral anticoagulants; and (3) delineating the optimal roles of percutaneous left atrial appendage occlusion and surgical left atrial appendage closure/excision. This report aims to promote innovative, impactful research that will lead to more personalized, effective use of stroke prevention strategies in people with AF.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
