Abstract
Aims: Infections have been associated with acute myocardial infarction (AMI), but differences in risk between infection types and age groups are unclear. This study aims to investigate whether infections are associated with subsequent AMI and whether the risk differs across infection sites and age groups.
Methods and results: Nationwide registers were used to include 702 596 adults hospitalized between 1987 and 2018 with either pneumonia (n = 344 319), urinary tract infection (UTI) (n = 270 101), soft tissue/bone infection (n = 66 718), central nervous system (CNS) infection (n = 17 025), or endocarditis (n = 4433). Patients were sex and age matched with two unexposed controls. Outcome was first-time AMI within 10 years. A time-dependent Cox proportional hazards model with cut-offs at 30 and 90 days was used for calculating adjusted hazard ratios (HRs). Pneumonia, UTI, and soft tissue/bone infection were associated with increased relative rates of AMI compared to matched, unexposed controls. Highest relative rates were found within the first 0-30 days post-exposure: pneumonia: HR 3.39 [95% confidence interval (CI) 3.15-3.65]; UTI: HR 2.44 (95% CI 2.21-2.70); soft tissue/bone infection: HR 1.84 (95% CI 1.45-2.33). Relative rates decreased over time but remained significantly elevated throughout the follow-up period and were increased in all age groups. No association was found for CNS infection and for endocarditis only at 31-90 days, HR 2.28 (95% CI 1.20-4.33).
Conclusion: Acute infections are associated with increased relative rates of AMI across different infection sites and age groups with higher relative rates found for pneumonia. This indicates that some infections may act as a trigger for AMI with a site and/or pathogen specific risk.
期刊介绍:
European Journal of Preventive Cardiology (EJPC) is an official journal of the European Society of Cardiology (ESC) and the European Association of Preventive Cardiology (EAPC). The journal covers a wide range of scientific, clinical, and public health disciplines related to cardiovascular disease prevention, risk factor management, cardiovascular rehabilitation, population science and public health, and exercise physiology. The categories covered by the journal include classical risk factors and treatment, lifestyle risk factors, non-modifiable cardiovascular risk factors, cardiovascular conditions, concomitant pathological conditions, sport cardiology, diagnostic tests, care settings, epidemiology, pharmacology and pharmacotherapy, machine learning, and artificial intelligence.
