Of the estimated 86 million U.S. adults with hypertension, 46% (~40 million) have poorly controlled or uncontrolled hypertension. Despite widespread recognition of the health risks of hypertension, sub-optimal treatment of hypertension remains a pernicious problem and is marked by disparities. Rates of hypertension control are lower among racial and ethnic minorities and socioeconomically disadvantaged groups. A substantial guideline-to-practice gap exists in hypertension management. This gap may contribute to greater disparities in cardiovascular disease and its outcomes among minority and disadvantaged groups. A critical feature of hypertension control is self-care; strategies that support greater self-care and hypertension control among vulnerable and high-risk patients are an important component of addressing the disparities in hypertension care. We will present results from the mGlide RCT a randomized controlled trial that will evaluate whether a mobile health technology based active partnership between health care teams and patients results in better hypertension control than a state-of-clinical care comparison for stroke survivors and persons at high risk of cardiovascular disease.
