Association between Air Pollution and Emergency Room Visits for Atrial Fibrillation.

ABSTRACT: Despite the large prevalence in the population, possible factors responsible for the induction of atrial fibrillation (AF) events in susceptible individuals remain incompletely understood. We investigated the association between air pollution levels and emergency department admissions for AF in Rome. We conducted a 14 years' time-series study to evaluate the association between the daily levels of air pollution (particulate matter, PM₁₀ and PM_2.5, and nitrogen dioxide, NO?) and the daily count of emergency accesses for AF (ICD-9 code: 427.31). We applied an over-dispersed conditional Poisson model to analyze the associations at different lags after controlling for time, influenza epidemics, holiday periods, temperature, and relative humidity. Additionally, we evaluated bi-pollutant models by including the other pollutant and the influence of several effect modifiers such as personal characteristics and pre-existing medical conditions. In the period of study, 79,892 individuals were admitted to the emergency departments of Rome hospitals because of AF (on average, 15.6 patients per day: min = 1, max = 36). Air pollution levels were associated with increased AF emergency visits within 24 h of exposure. Effect estimates ranged between 1.4% (0.7-2.3) for a 10 µg/m³ increase of PM₁₀ to 3% (1.4-4.7) for a 10 µg/m³ increase of PM_2.5 at lag 0-1 day. Those effects were higher in patients ?75 years for all pollutants, male patients for PM₁₀, and female patients for NO?. The presence of previous cardiovascular conditions, but not other effect modifiers, increase the pollution effects by 5-8% depending on the lag. This study found evidence that air pollution is associated with AF emergency visits in the short term.

Project description:BACKGROUND:Arrhythmia is a common cardiovascular event that is associated with increased cardiovascular health risks. Previous studies that have explored the association between air pollution and arrhythmia have obtained inconsistent results, and the association between the two in China is unclear. METHODS:We collected daily data on air pollutants and meteorological factors from 1st January 2014 to 31st December 2016, along with daily outpatient visits for arrhythmia in Hangzhou, China. We used a quasi-Poisson regression along with a distributed lag nonlinear model to study the association between air pollution and arrhythmia morbidity. RESULTS:The results of the single-pollutant model showed that each increase of 10??g/m3 of Fine particulate matter (PM2.5), Coarse particulate matter (PM10), Sulphur dioxide (SO2), Nitrogen dioxide (NO2), and Ozone (O3) resulted in increases of 0.6% (-?0.9, 2.2%), 0.7% (-?0.4, 1.7%), 11.9% (4.5, 19.9%), 6.7% (3.6, 9.9%), and?-?0.9% (-?2.9, 1.2%), respectively, in outpatient visits for arrhythmia; each increase of 1?mg/m3 increase of carbon monoxide (CO) resulted in increase of 11.3% (-?5.9, 31.6%) in arrhythmia. The short-term effects of air pollution on arrhythmia lasted 3?days, and the most harmful effects were observed on the same day that the pollution occurred. Results of the subgroup analyses showed that SO2 and NO2 affected both men and women, but differences between the sexes were not statistically significant. The effect of SO2 on the middle-aged population was statistically significant. The effect of NO2 was significant in both the young and middle-aged population, and no significant difference was found between them. Significant effects of air pollution on arrhythmia were only detected in the cold season. The results of the two-pollutants model and the single-pollutant model were similar. CONCLUSIONS:SO2 and NO2 may induce arrhythmia, and the harmful effects are primarily observed in the cold season. There is no evidence of PM2.5, PM10, CO and O3 increasing arrhythmia risk. Special attention should be given to sensitive populations during the high-risk period.
