Qaseem A, Wilt TJ, Rich R, et al. Pharmacologic Treatment of Hypertension in Adults Aged 60 Years or Older to Higher Versus Lower Blood Pressure Targets: A Clinical Practice Guideline From the American College of Physicians and the American Academy of Family Physicians. Ann Intern Med. 2017;166:430-7.
Review question
In older adults who have hypertension (high blood pressure), what are the best blood pressure targets?
Background
Blood pressure is reported with 2 numbers, such as 120/80 mm Hg. The first number is the systolic blood pressure and it tells you how much pressure your blood exerts against your artery walls when your heart beats. The second number is the diastolic blood pressure and it tells you how much pressure your blood exerts on your artery walls between heart beats.
Hypertension is blood pressure that is higher than normal. It is a very common disease and increases a person’s risk for other diseases, such as heart attack and stroke, and death. How much a person’s blood pressure should be lowered, especially for people 60 years of age or older, is not known.
How the review was done
The researchers did a systematic review, searching for studies up until September 2016.
They found 21 randomized controlled trials and 3 cohort studies of different blood pressure targets.
The key features of the studies were:
- people were 60 years of age or older and had hypertension; and
- the aim was to lower systolic blood pressure (first number) to less than 150 mm Hg or to less than 140 mm Hg.
What the researchers found
Treatment targets should always be determined after discussion between the person and their doctor about the potential benefits and harms of lowering blood pressure.
Adults 60 years of age or older with systolic blood pressure of 150 mm Hg or more should be treated with a goal of reducing systolic blood pressure to less than 150 mm Hg.
Adults 60 years of age or older who have had a stroke or transient ischemic attack (mini stroke) should be treated with a goal of reducing their systolic blood pressure to less than 140 mm Hg.
Adults 60 years of age or older who are at high risk for cardiovascular events (e.g., heart attack) should be treated with a goal of reducing their systolic blood pressure to less than 140 mm Hg, but this decision should be made on an individual basis.
Conclusion
In adults 60 years of age or older, blood pressure treatment targets should be determined based on a patient’s history and risk factors.
American College of Physicians’ and American Academy of Family Physicians recommendations for people 60 years of age or older with hypertension (high blood pressure)
| Conditions | Recommendations and evidence | Quality rating |
| Adults 60 years of age or older | Treatment targets should always be determined after discussion with the doctor about the potential benefits and harms of lowering blood pressure. | Not applicable |
| Adults 60 years of age or older with systolic blood pressure 150 mm Hg or more | The goal should be to treat to reduce systolic blood pressure to less than 150 mm Hg. | High |
| Adults 60 years of age or older who have had a stroke or transient ischemic attack | The goal should be to treat to reduce systolic blood pressure to less than 140 mm Hg | Moderate |
| Adults 60 years of age or older who are at high risk for cardiovascular events (e.g., heart attack) | The goal of treating to reduce systolic blood pressure to less than 140 mm Hg should be considered, but this decision should be made on an individual basis | Low |

UpToDate - patient informationBlood is transported from the heart to other organs and areas of the body by the arteries. Blood pressure is the pressure that is exerted on the inner walls of these arteries by blood. Generally, to be diagnosed with high blood pressure, you must exhibit continuously high blood pressure at two different doctor's visits spaced at least 7 days apart. -
High blood pressure
Informed Health OnlineHigh blood pressure can lead to a variety of medical issues if left untreated. It is often symptomless until it becomes extremely high, at which point people can experience vision problems and dizziness. High amounts of salt and alcohol intake, excess weight, lack of physical activity, family history, certain medications, and an overactive thyroid are some causes and risk factors for high blood pressure. Strategies such as consuming less salt, exercising more, losing weight, and medication prescribed by a health care provider can be used to help lower blood pressure.
