Background: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are rare in high-income countries; however, in Aotearoa New Zealand ARF and RHD disproportionately affect Indigenous Māori and Pacific Peoples. This narrative review explores the evidence regarding non-surgical management of patients with clinically significant valve disease or heart failure due to RHD., Methods: Medline, EMBASE and Scopus databases were searched, and additional publications were identified through cross-referencing. Included were 28 publications from 1980 onwards., Results: Of the available interventions, improved anticoagulation management and a national RHD register could improve RHD outcomes in New Zealand. Where community pharmacy anticoagulant management services (CPAMS) are available good anticoagulation control can be achieved with a time in the therapeutic range (TTR) of more than 70%, which is above the internationally recommended level of 60%. The use of pharmacists in anticoagulation control is cost-effective, acceptable to patients, pharmacists, and primary care practitioners. There is a lack of local data available to fully assess other interventions; including optimal therapy for heart failure, equitable access to specialist RHD care, prevention, and management of endocarditis., Conclusion: As RHD continues to disproportionately affect Indigenous and minority groups, pro-equity tertiary prevention interventions should be fully evaluated to ensure they are reducing disease burden and improving outcomes in patients with RHD., (Copyright © 2022 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Acute rheumatic fever (ARF) and its sequela rheumatic heart disease (RHD) remain significant causes of morbidity and mortality. In New Zealand, ARF almost exclusively affects Indigenous Māori and Pacific children. This narrative review aims to present secondary interventions to improve early and accurate diagnosis of ARF and RHD, in order to minimise disease progression in New Zealand. Medline, EMBASE and Scopus databases were searched as well as other electronic publications. Included were 56 publications from 1980 onwards. Diagnosing ARF and RHD as early as possible is central to reducing disease progression. Recent identification of specific ARF biomarkers offer the opportunity to aid initial diagnosis and portable echocardiography has the potential to detect undiagnosed RHD in high-risk areas. However, further research into the benefits and risks to children with subclinical RHD is necessary, as well as an economic evaluation., (© 2021 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Rheumatic heart disease (RHD) is a large, preventable, global public health burden. In New Zealand (NZ), acute rheumatic fever (ARF) and RHD rates are highest for Māori and Pacific children. This structured review explores the evidence for primary prevention interventions to diagnose and effectively treat group A Streptococcus (GAS) pharyngitis and skin infections to reduce rates of ARF and RHD. Medline, EMBASE and Scopus databases were searched as well as other electronic publications. Included were 50 publications from 1980 onwards. This review has identified that there is little available evidence for effective primary prevention strategies to reduce ARF rates in NZ. However, two primary intervention strategies that should be considered by communities at high-risk of ARF are: the use of school-based clinics to identify and treat GAS pharyngitis and GAS skin infections; and intramuscular benzathine penicillin G with lignocaine analgesia in children who present with a GAS positive throat., (© 2021 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

We describe trends in acute rheumatic fever (ARF), rheumatic heart disease (RHD), and RHD deaths among population groups in New Zealand. We analyzed initial primary ARF and RHD hospitalizations during 2000-2018 and RHD mortality rates during 2000-2016. We found elevated rates of initial ARF hospitalizations for persons of Māori (adjusted rate ratio [aRR] 11.8, 95% CI 10.0-14.0) and Pacific Islander (aRR 23.6, 95% CI 19.9-27.9) ethnicity compared with persons of European/other ethnicity. We also noted higher rates of initial RHD hospitalization for Māori (aRR 3.2, 95% CI 2.9-3.5) and Pacific Islander (aRR 4.6, 95% CI 4.2-5.1) groups and RHD deaths among these groups (Māori aRR 12.3, 95% CI 10.3-14.6, and Pacific Islanders aRR 11.2, 95% CI 9.1-13.8). Rates also were higher in socioeconomically disadvantaged neighborhoods. To curb high rates of ARF and RHD, New Zealand must address increasing social and ethnic inequalities.
