Digital Health: New Approaches in Hypertension Management

Hypertension is a key risk factor for cardiovascular disease. Globally, approximately a third of people with hypertension remain undiagnosed, and of those diagnosed, about half are not taking antihypertensive medication. The World Health Organization has estimated that globally hypertension directly or indirectly causes the deaths of at least nine million people every year. There is a trend towards self-monitoring of blood pressure (BP), where patients are empowered to be involved in hypertension screening and diagnosis. Novel technology, including smartphones and Blue-tooth® enabled telemonitoring, are new tools that are likely to be increasingly important in hypertension management. Several studies have shown the benefit of self-monitoring of BP coupled with co-interventions (such as telemonitoring) in improving BP management. However, these new technologies must be properly assessed and clinically validated prior to widespread implementation in the general population, or within special groups. In this mini-review, we examine how technology might improve the detection and management of hypertension.
