ABSTRACT:
Hypertension constitutes the predominant etiological factor for cardiovascular morbidity and premature mortality worldwide, with a disproportionate manifestation among low- and middle-income countries (LMICs) where blood pressure (BP) control rates remain critically low. Conventional management approaches are heavily reliant on frequent in-person clinic visits and long-term medication adherence often complicated by geographical barriers, financial limitations and education gaps in resource-constrained settings. Within the broader context of global health disparities and technological innovation, hypertension emerges as a paradigmatic case study for examining the potential of the digital age in a healthcare context. Remote patient monitoring (RPM) and mobile health (mHealth) interventions appear to be promising alternatives to conventional management, leveraging technological evolution to propagate access, reduce expenditure and improve self-management of hypertension. This narrative review synthesis evidence from 11 original research studies published between 2015 and 2025, examining the effectiveness of RPM and mHealth interventions in managing hypertension among adults in LMICs. The findings uncover the mass potential of telehealth interventions in managing hypertension demonstrating notable but fragmented evidence of BP reduction. While short term clinical benefits are marked, long-term outcomes appear modest and lack consistency with further research required to substantiate its effects. Despite the upside to the technology, challenges persist in several realms. The concerns remain largely around usability issues, digital inequities and the absence of long-term follow up data. The evidence is pronounced in highlighting that intervention success is determined as much by cultural adaptation, seamless health system integration and patient engagement as by the sophistication of the technology itself. This review contributes to addressing an evidence gap in the field of digital health in LMICs emphasising the significance of equity-focused, culturally adapted and economically sustainable models to translate the mere potential of RPM and mHealth solutions into lasting improvements to minimise the burden of hypertension.
