ORIGINAL RESEARCHAspirin Use and Risk of Atrial Fibrillation inside the Physicians’ Overall health StudyPeter Ofman, MD, MSc; Andrew B. Petrone, MPH; Adelqui Peralta, MD; Peter Hoffmeister, MD; Christine M. Albert, MD, MPH; Luc Djousse, MD, MPH, ScD; J. Michael Gaziano, MD, MPH; Catherine R. Rahilly-Tierney, MD, MPHBackground—Inflammatory processes happen to be connected with an enhanced danger of atrial fibrillation (AF), potentially enabling for preventive therapy by anti-inflammatory agents including aspirin. Having said that, the effect of chronic aspirin on the incidence of AF has not been evaluated in a prospective cohort followed for an extended period. PKCĪ¹ supplier Methods and Results—This study was comprised of a prospective cohort of 23 480 male participants from the Physicians’ Overall health Study. Aspirin intake and covariates had been estimated employing self-reported 5-HT2 Receptor Modulator MedChemExpress questionnaires. Incident AF was ascertained by way of yearly follow-up questionnaires. Cox’s regression, with adjustment for many covariates, was made use of to estimate relative risk of AF. Average age at baseline was 65.1.9 years. For the duration of a imply follow-up of ten.0 years, 2820 instances of AF have been reported. Agestandardized incidence prices have been 12.6, 11.1, 12.7, 11.three, 15.eight, and 13.81000 person-years for people reporting baseline aspirin intake of 0, 14 days per year, 14 to 30 days per year, 30 to 120 days per year, 121 to 180 days per year, and 180 days per year, respectively. Multivariable adjusted hazard ratios (95 self-assurance interval) for incident AF had been 1.00 (reference), 0.88 (0.76 to 1.02), 0.93 (0.76 to 1.14), 0.96 (0.80 to 1.14), 1.07 (0.80 to 1.14), and 1.04 (0.94 to 1.15) across consecutive categories of aspirin intake. Analysis in the data making use of time-varying Cox’s regression model to update aspirin intake over time showed similar results. Conclusions—In a big cohort of males followed for a long period, we did not locate any association among aspirin use and incident AF.
