Abstract
Objectives The aim of this study was to determine the causes of death among Asian non-valvular atrial fibrillation (AF) patients who were registered in a nationwide AF registry, and to investigate the differences in the causes of death in AF patients compared between those who were taking and not taking oral anticoagulant (OAC). Methods The COhort of antithrombotic use and Optimal INR Level in patients with non-valvular Atrial Fibrillation in Thailand (COOL-AF) study enrolled non-valvular AF patients from 27 centers in Thailand during 2014–2017 to create the COOL-AF Thailand registry. Cause of death was classified as cardiovascular (CV) death, non-CV death, or undetermined cause of death. All events were evaluated and verified by an independent adjudication committee. Results There was a total of 3,405 patients (mean age: 67.8 years, 41.8% female), and the mean follow-up duration was 31.8±8.7 months. Three hundred and eighty patients (11.2%) died during follow-up. CV death, non-CV death, and undetermined cause accounted for 121 (31.8%), 189 (49.7%), and 70 (18.4%) patients, respectively. Of those with a known cause of death, heart failure (10%), intracranial hemorrhage (ICH; 10%), sudden cardiac death (6.8%), and ischemic stroke (5.8%) were the most often observed causes of death. Concerning non-CV death, infection/sepsis (27.7%), cancer (5.5%), respiratory (5.2%), and major bleeding (4.5%) were the most prevalent causes of death. The use and type of OAC were found to be major determinants of ICH and major bleeding incidence. Conclusion Death due to ischemic stroke was responsible for only 4.7% of all deaths in Asian AF patients. Non-CV death, such as infection/sepsis or malignancy, was more far more prevalent than CV death in Asian AF patients. An improved integrated care approach is needed to reduce the prevalence of non-CV death in Asian AF patients.
