"We found [in a study] that elderly high blood pressure patients with other illnesses were generally half as likely to take their medication for high blood pressure," says researcher Philip Wang, MD, assistant professor of psychiatry, medicine, and health care policy at Harvard Medical School, in a news release.
"This is a little surprising when you consider the magnitude and consistency of the effectiveness of high blood pressure medication," Wang says.
The elderly frequently suffer from more than one chronic medical condition. "Awareness needs to be raised to the fact that high blood pressure is as important to treat as more symptomatic conditions," says Wang.
Blood Pressure Treatment Often Neglected
In the study, researchers analyzed information provided by more than 50,000 men and women over age 65 with high blood pressure who were enrolled in Pennsylvania's state prescription benefits program.
Researchers found that elderly people with other conditions not related to heart disease were much less likely to take their prescribed blood pressure pills.
For example, the likelihood of the elderly taking their high blood pressure medication was:
- 57% less if they had asthma or chronic obstructive pulmonary disease (COPD)
- 50% less if they had depression
- 41% less if they had gastrointestinal disorders
- 37% less if they had osteoarthritis
Researchers say the results are alarming because only 60% of people with high blood pressure are treated, and of those only about one-third have their blood pressure levels adequately controlled.
The results are problematic in light of the very clear evidence of the benefit of high blood pressure therapy in preventing and reducing damage to multiple organs, they write.
