During the last few years, a number of studies have highlighted the failure of physicians to measure blood pressure correctly, which could mean patients are taking unnecessary medicines.
About a third of older people have "white coat" hypertension, which means their blood pressure goes up simply because they are stressed about visiting a doctor. This type of high blood pressure doesn't necessarily indicate an underlying medical problem.
The National Clinical Guideline Center in London found that monitoring the blood pressure of older people in their homes instead of in doctors' offices is a better option, saving a patient nearly $600 over his or her lifetime and providing a better quality of life. Patients should have their blood pressures treated only after having at least two elevated blood pressure readings at home. Physicians should alter blood pressure medications based on home measurements, not on blood pressures obtained in their offices.
Another recent study from the United Kingdom found that blood pressure should be measured in both arms. A difference of 10 to 20 mm Hg in the systolic blood pressure (the higher one) predicted an increased risk of stroke, heart disease and peripheral vascular disease. Thus, the first time you see your doctor and then at least every five years, have your blood pressure measured in both arms.
Blood pressure also should be measured standing as well as sitting or lying down. This is because a drop in blood pressure is very common in people who are older, have diabetes or take antihypertensive medications. This drop can occur immediately or after three to five minutes after standing, and is associated with falls and cardiovascular disease.
In addition, some older adults have hardening of the arteries, which falsely elevates blood pressures. Your physician needs to take this into account before aggressively treating your blood pressure.
Finally, studies show that the systolic blood pressure for most older people should be kept below 160 mm Hg. There is no evidence to support a benefit to a lower reading.
