Measure
Usual Care Group
Standard of care BP medication will usually be started if a subject's BP consistently exceeds 150/100 mmHg at any point. Usual care: The usual care group will be given anti-hypertensive medications (i.e. beta blocker, calcium channel blocker, etc) if a subject's BP consistently exceeds 150/100 mmHg consistently.
Intervention (Tight Blood Pressure Control) Group
BP medication will be started if a subject's hospital BP consistently exceeds 140/90 mmHg or her home BP consistently exceeds 135/85 mmHg. Tight blood pressure control: The intervention group will be initiated on blood pressure medications (i.e. beta blocker, calcium channel blocker, etc) if a subject's hospital BP consistently exceeds 140/90 mmHg or home BP consistently exceeds 135/85 mmHg.
