Registry of Atrial Fibrillation in Latin America: Primary Results of the LACROSS Study

Listen to this summary

The LACROSS study aimed to assess the management and clinical outcomes of atrial fibrillation in Latin America, focusing on the prevalence of oral anticoagulation use among patients. The study found that nearly 30% of the 2,012 patients were not receiving anticoagulation, with significant associations between adverse outcomes and factors such as age, diabetes, and renal disease. These results underscore the critical need to address gaps in anticoagulation therapy and improve patient care in the region.
