Intervention: Exercise
Description: Blood pressure (BP) target of \< 140/90 mmHg (or \< 130/80 mmHg for diabetics or with chronic kidney disease) as recommended by the 7th Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7). BP control efforts will be open-label and will include a combination of recommended life-style modifications (i.e., exercise, weight loss, low sodium diet, smoking cessation), and pharmaceutical therapy based on JNC 7 protocol driven guidelines with the following adaptations: 1) use of a diuretic that is appropriate to renal function (eGFR\< 40 ml/min/1.73 m2: a loop diuretic; eGFR\> 40 ml/min/1.73 m2: a thiazide); 2) use of automated reminders if BP exceeds target for \> 4 weeks without a medication titration; 3) use of a second diuretic when taking 4 or more anti-hypertensives without adequate achievement of BP target level; and 4) automated alerts to study personnel for potential drug interactions.
