      Cardiovascular disease (CVD) is a leading global cause of death and morbidity and prevention needs to be strengthened to tackle this. Mobile health (mHealth) might present a novel and effective solution in CVD prevention, and interest in mHealth has grown dramatically since the advent of the smartphone. In this review, we discuss mHealth interventions that target multiple cardiovascular risk factors simultaneously in the context of primary as well as secondary prevention. There is some evidence that mHealth interventions improve a range of individual CVD risk factors, but a relative paucity of evidence on mHealth interventions improving multiple CVD risk factors simultaneously. The existing data suggest mHealth programs improve overall CVD risk, at least in the short term. Interpretation of the evidence is difficult in the context of poor methodology and mHealth modalities often being a part of large complex interventions. In this review we identify a number of unanswered questions including: which mode of mHealth (or combination of interventions) would be most effective, what is the durability of intervention effects, and what degree of personalization and interactivity is required.


      La maladie cardiovasculaire (MCV) est une des principales causes de mortalité et de morbidité dans le monde et il est urgent de mettre l’accent sur sa prévention pour s’attaquer à ce problème. Les applications mobiles en santé pourraient constituer une solution innovante et efficace pour la prévention de la MCV, et l’intérêt pour ce type de technologie a connu un essor fulgurant depuis les premiers téléphones intelligents. Dans cette revue, nous examinons les applications mobiles en santé qui ciblent simultanément plusieurs facteurs de risque cardiovasculaire dans le contexte de la prévention tant primaire que secondaire. Les données probantes dont on dispose indiquant que les interventions utilisant des applications mobiles en santé ont pour effet d’améliorer plusieurs facteurs de risque de MCV individuels sont relativement plus nombreuses que celles attestant une amélioration simultanée des facteurs de risque de MCV multiples. Les données existantes laissent croire que les programmes d’applications mobiles en santé diminuent le risque de MCV global, du moins à court terme. L’interprétation des données probantes est difficile dans le contexte d’une méthodologie inadéquate et du fait que les modalités utilisant des applications mobiles en santé sont souvent intégrées à des interventions complexes à grande échelle. Dans cette revue, nous recensons plusieurs questions encore sans réponse, y compris les suivantes : quel serait le mode d’utilisation le plus efficace des applications mobiles en santé (ou d’une combinaison d’interventions), quelle est la durabilité des effets de l’intervention, et quel est le degré de personnalisation et d’interactivité requis.
