ClinConnect Summary

The Atrial Fibrillation Data Linkage Non-Interventional Study aims to explore how the characteristics and effects of atrial fibrillation (AF) change over time. Atrial fibrillation is a common heart condition where the heart beats irregularly or too fast. This study will analyze existing patient data from a specific hospital and national health records in Korea to gain insights into this condition's impact on patients. It's important to note that this study will not involve recruiting new patients; instead, it will focus on information already collected.

To be eligible for this study, participants must have been diagnosed with atrial fibrillation at a hospital or clinic in Korea between January 2010 and December 2020, and they should be at least 18 years old. However, individuals with certain heart valve diseases will not be included in the study. Since this is a data analysis study, participants will not have to attend appointments or undergo any new treatments—it's all about understanding how atrial fibrillation affects people over time using the information already available.
