Medical guidelines for blood pressure control have dropped to 120/80, sparking debate among physicians about aggressive treatment for older adults. The American Heart Association and American College of Cardiology now recommend medication for systolic readings over 130, down from the previous 140 threshold. Recent studies linking hypertension to dementia have pushed doctors toward tighter control, particularly for patients over 65.

Dr. Mark Supiano, a geriatrician at the University of Utah, initially treated a 78-year-old patient with mild cognitive impairment less aggressively than he would today. After studies showed cognitive benefits from lower readings, he added a third medication, reducing her systolic pressure to 120 or below. The Sprint trial, which found substantial cardiovascular benefits from intensive treatment, stopped early because denying patients lower readings was considered unethical.

Home monitoring has become essential as office readings often show white-coat syndrome. Doctors now ask patients to track blood pressure twice daily for weeks before appointments. While most medications cost only $5 monthly as generics, skeptics like Dr. Rita Redberg argue that pushing readings from 135 to 120 may cause more anxiety than benefit. The guidelines remain controversial for frail elderly patients where quality of life considerations outweigh potential cardiovascular gains.
