This randomized controlled trial investigates the efficacy and safety of mobile health intervention in managing hypertension after Intracerebral Hemorrhage (ICH).

140 ICH survivors will be randomized into mobile health intervention (MOBILE) and the usual care group for hypertension management. All subjects will be educated on the importance of hypertension control after ICH and given lifestyle advice, including the DASH diet. Subjects in the MOBILE group will enter their home blood pressure (BP) measurements into a mobile stroke App (WeRISE) daily, and the study team will regularly review the BP measurements through a backend system. A protocol-based intervention via phone calls, which includes anti-hypertensive drug adjustment and reinforcement of lifestyle modification, will be implemented. Subjects in the usual care group will have their hypertension managed by their respective treating physicians. All subjects will be followed up for 26 weeks. The primary and secondary endpoints include the rate of controlled hypertension at 12 and 26 weeks.
