Using data from a national study, Johns Hopkins researchers determined that using heart computed tomography (CT) scans can help personalize treatment in patients whose blood pressure falls in the gray zone of just above normal or mild high blood pressure. Previously, the appropriate blood pressure treatment for these patients used risk calculations and some guesswork, potentially leaving many vulnerable to heart disease or taking drugs they do not need. Nearly one in three adults in the United States has prehypertension, blood pressure higher than normal but not considered high yet.
