As an example, older adult patients may be at particularly high risk for cerebral or myocardial ischemia if the blood pressure is lowered excessively and/or too rapidly. In such patients, who often will have a high pulse pressure (eg, diastolic blood pressure <90 mmHg with systolic blood pressure ≥180 mmHg), the initial goal blood pressure may need to be achieved even more slowly (eg, over a week or more).

  • Conclusions and Relevance  In this cohort study, hypertension was common among medical inpatients, but antihypertensive treatment intensification was not. Intensification of therapy without signs of end-organ damage was associated with worse outcomes.Conclusions and Relevance  In this cohort study, hypertension was common among medical inpatients, but antihypertensive treatment intensification was not.
