Abstract
Background: Acute respiratory infections are associated with increased risk of myocardial infarction (MI) and stroke, however, the role of different organisms is poorly characterised. Methods: We undertook a time-series analysis of English hospital admissions for MI and stroke (age-stratified: 45-64, 65-74, 75+ years), laboratory-confirmed viral respiratory infections and environmental data for 2004-2015. Weekly counts of admissions were modelled using multivariable Poisson regression with weekly counts of respiratory viruses (influenza, parainfluenza, rhinovirus, respiratory syncytial virus (RSV), adenovirus or human meta-pneumovirus (HMPV)) investigated as predictors. We controlled for seasonality, long-term trends and environmental factors. Results: Weekly hospital admissions in adults aged 45+ years averaged 1347 (IQR 1217-1541) for MI and 1175 (IQR 1023-1395) for stroke. Median numbers of respiratory infections ranged from 11 cases per week (IQR 5-53) for influenza to 55 (IQR 7-127) for rhinovirus. In the adjusted models, all viruses except parainfluenza were significantly associated with MI and ischaemic stroke admissions in those aged 75+. Among 65-74 year olds, adenovirus, rhinovirus and RSV were associated with MI but not ischaemic stroke admissions. Respiratory infections were not associated with MI or ischaemic stroke in people aged 45-64, nor with haemorrhagic stroke in any age group. An estimated 0.4-5.7% of MI and ischaemic stroke admissions may be attributable to respiratory infection, with greater excess burden during weeks with high circulating virus levels. Conclusions: We identified small but strongly significant associations in the timing of respiratory infection (with HMPV, RSV, influenza, rhinovirus and adenovirus) and MI or ischaemic stroke hospitalisations in the elderly.
