New Guideline for Treatment of Hypertension in Older Adults

The American College of Physicians (ACP) and the American Academy of Family Physicians (AAFP) have published an evidence-based clinical practice guideline on the appropriate systolic blood pressure target for adults 60 years old and older with hypertension. The joint guideline was published in January 17th 2017 issue of Annals of Internal Medicine and a summary of the guideline will be published in the March/April 2017 issue of the Annals of Family Medicine.

A release from ACP explains that hypertension, an elevation of systemic arterial blood pressure, is one of the most common chronic diseases in the United States. About 65 percent of adults in the U.S. over the age of 60 have hypertension, and the disease affects about 29 percent of all adults in the nation.

ACP and AAFP are two of the largest physician organizations in the U.S. representing primary care doctors. Their combined 272,900 members, including internal medicine physicians (internists) and family physicians, treat the majority of patients in the U.S. with hypertension.

ACP and AAFP recommend that physicians initiate treatment in adults aged 60 years old and older with persistent systolic blood pressure at or above 150 millimeters of mercury (mm Hg) to achieve a target systolic blood pressure of less than 150 mm Hg to reduce the risk of mortality, stroke, and cardiac events.

The release quotes Nitin S. Damle, MD, MS, MACP, president, as saying, “The evidence showed that any additional benefit from aggressive blood pressure control is small, with a lower magnitude of benefit and inconsistent results across outcomes. Most benefits of targeting of less than 150 mm Hg apply to individuals regardless of whether or not they have diabetes.”

The guideline notes that some patients may have falsely elevated readings in clinical settings (“white coat hypertension”). Therefore, it is important for physicians to ensure that they are accurately measuring blood pressure before initiating or changing treatment for hypertension.

“The most accurate measurements come from multiple blood pressure measurements made over time,” said John Meigs, Jr., MD, president, AAFP “These may include multiple measurements in clinical settings or ambulatory or home-monitoring.”

The guideline includes two additional recommendations:

– ACP and AAFP recommend that physicians consider initiating or intensifying drug therapy in adults aged 60 years old and older with a history of stroke or transient ischemic attack to achieve a target systolic blood pressure of less than 140 mm Hg to reduce the risk of recurrent stroke.

– ACP and AAFP recommend that physicians consider initiating or intensifying pharmacological treatment in some adults aged 60 years old and older at high cardiovascular risk, based on individualized assessment, to achieve a target systolic blood pressure of less than 140 mm Hg to reduce the risk of stroke or cardiac events.
