Abstract

Abstract: Background: Rheumatic heart disease (RHD) is a debilitating sequela of acute rheumatic fever (ARF), caused by Group A streptococcus (GAS) infection. Repeated episodes of ARF results in valvular damage over time. As a preventable disorder which was once common worldwide, RHD has largely been eradicated in affluent nations due to widespread availability of penicillin, improvement in socioeconomic standards and advancements in health and social infrastructures. However, it has been speculated that the global refugee crisis, especially in Europe, might contribute to a resurgence of RHD cases in these regions. Purpose: This observational study aimed to analyse trends in RHD incidence and mortality rates in European Union 15+ (EU15+) over a 29-year period. Methods: Data was obtained from the Global Burden of Disease database. Age-standardised mortality and incidence rates for RHD were extracted for the EU15+ countries for the years 1990–2019. Trends were subsequently analysed using Joinpoint regression analysis. Results: Over the 29-year period, an overall declining trend in RHD incidence and mortality across EU 15+ nations was observed. The United Kingdom demonstrated the largest decrease in RHD incidence amongst females (−54.9%) and Finland amongst males (−55.3%). Both RHD incidence and mortality were higher among females compared to males across EU15+ countries over the observed period. The most recent incidence trends, starting predominantly after 2014, demonstrated a rise in RHD incidence in most countries. For both sexes, increases were seen in Australia, Belgium, Ireland, Italy, Netherlands, Norway, Sweden and USA. For males specifically, increase in RHD incidence was seen in Spain, and Finland, and for females only in Canada and Ireland. The recent increasing RHD incidence rates ranged from +0.4% to + 24.7% for males and +0.6% to +11.4% for females. Conclusion: Whilst overall there are decreases in incidence and mortality from RHD, we observe more than half of EU15+ countries have increasing incidence trends in RHD in recent years. This increasing trend primarily started after 2014, overlapping with the start of the European migration crisis. Although speculative, disparities in access to healthcare for migrants, amongst other socioeconomic factors, may be potential causes; subsequently, further efforts by governments and public health officials are required to recognise and control the resurgence of RHD in high income nations.
