Cardiovascular benefits of early rhythm control and healthy lifestyle in young atrial fibrillation

Type: article

Abstract: BACKGROUND: Limited evidence exists regarding the consistent and synergistic benefits of early rhythm control (ERC) and healthy lifestyle (HLS) on major adverse cardiovascular events (MACEs) in young patients with atrial fibrillation (AF). AIMS: To evaluate the individual and synergistic benefits of ERC and HLS on MACEs in young AF patients. METHODS: In an observational cohort study using a Korean nationwide claims database, new-onset AF patients (age 20-<65 years) were included. ERC was defined as rhythm control treatment within 2 years of AF diagnosis, and HLS as having at least two healthy lifestyle behaviours (quitting smoking/abstaining from alcohol/regular exercise). Patients were grouped into: without ERC and HLS (n = 28,809); HLS alone (n = 41,827); ERC alone (n = 10,962); and both ERC and HLS (n = 16,594). The primary outcome was MACEs, and the secondary outcomes included ischaemic stroke, myocardial infarction, heart failure hospitalisation and all-cause death. Multivariable Cox regression analysis assessed HR for MACEs. RESULTS: -VASc score, 1.6 ± 1.3). The ERC and HLS groups were significantly associated with a lower risk of MACEs (ERC: HR .765; 95% CI .722-.810, p < .001 and HLS: HR .813, 95% CI .770-.860, p < .001) compared to those without ERC and HLS; both the ERC and HLS groups were associated with the lowest risk of MACEs (HR .616, 95% CI .569-.666, p < .001). Similar trends were observed for ischaemic stroke among secondary outcomes. CONCLUSIONS: ERC and HLS were individually and synergistically associated with a significantly lower risk of MACEs in young AF patients.
