Pregnancy-related cardiac complications: A consequence of the burden of rheumatic heart disease in sub-Saharan Africa

Standardizing clinical care measures of rheumatic heart disease in pregnancy: A qualitative synthesis

BACKGROUND

Rheumatic heart disease (RHD) is a preventable cardiac condition that escalates risk in pregnancy. Models of care informed by evidence-based clinical guidelines are essential to optimal health outcomes. There are no published reviews that systematically explore approaches to care provision for pregnant women with RHD and examine reported measures. The review objective was to improve understanding of how attributes of care for these women are reported and how they align with guidelines.

METHODS

A search of 13 databases was supported by hand-searching. Papers that met inclusion criteria were appraised using CASP/JBI checklists. A content analysis of extracted data from the findings sections of included papers was undertaken, informed by attributes of quality care identified previously from existing guidelines.

RESULTS

The 43 included studies were predominantly conducted in tertiary care centers of low-income and middle-income countries. Cardiac guidelines were referred to in 25 of 43 studies. Poorer outcomes were associated with higher risk scores (detailed in 36 of 41 quantitative studies). Indicators associated with increased risk include anticoagulation during pregnancy (28 of 41 reported) and late booking (gestation documented in 15 of 41 studies). Limited access to cardiac interventions was discussed (19 of 43) in the context of poorer outcomes. Conversely, early assessment and access to regular multidisciplinary care were emphasized in promoting optimal outcomes for women and their babies.

CONCLUSIONS

Despite often complex care requirements in challenging environments, pregnancy provides an opportunity to strengthen health system responses and address whole-of-life health for women with RHD. A standard set of core indicators is proposed to more accurately benchmark care pathways, outcomes, and burden.

Rheumatic heart disease

Rheumatic heart disease, often neglected by media and policy makers, is a major burden in developing countries where it causes most of the cardiovascular morbidity and mortality in young people, leading to about 250,000 deaths per year worldwide. The disease results from an abnormal autoimmune response to a group A streptococcal infection in a genetically susceptible host. Acute rheumatic fever--the precursor to rheumatic heart disease--can affect different organs and lead to irreversible valve damage and heart failure. Although penicillin is effective in the prevention of the disease, treatment of advanced stages uses up a vast amount of resources, which makes disease management especially challenging in emerging nations. Guidelines have therefore emphasised antibiotic prophylaxis against recurrent episodes of acute rheumatic fever, which seems feasible and cost effective. Early detection and targeted treatment might be possible if populations at risk for rheumatic heart disease in endemic areas are screened. In this setting, active surveillance with echocardiography-based screening might become very important.
