It's
time to question the common belief that patients receiving intensive
blood pressure treatment are prone to falling and breaking bones. A
comprehensive study in people ages 40 to 79 with diabetes, led by Karen
Margolis, MD, of HealthPartners Institute for Education and Research in the US, found no evidence supporting this belief. The study appears in the Journal of General Internal Medicine, published by Springer.
Evidence from various clinical trials shows that cardiovascular events such as strokes can be prevented by treating high blood pressure
(hypertension).. However, physicians and patients still often express
concern that its tight control may increase a person's risk of low blood
pressure (hypotension) and subsequent falls and fractures. Scientific
data to support this notion are sparse. Therefore, Margolis and her
associates compared the number of falls and fractures of type 2 diabetes
patients receiving two types of blood pressure treatment. The intensive
group (which included 1,534 participants) received treatment aimed at a
systolic blood pressure of <120 for="" group="" hg.="" hg="" mm="" p="" participants="" standard="" target="" the="" was="" while="">

Participants were all part of ACCORD-BONE, an ancillary study of the
Action to Control Cardiovascular Risk in Diabetes (ACCORD) randomized
trial, which tested how more
intensive treatment of blood sugar, blood pressure and lipids affected
cardiovascular disease outcomes in people with diabetes. Participants in
the ACCORD-BONE study were, on average, about 62 years old; none were
80 or older. The results show that patients who received intensive blood
pressure treatment did not fall more than less intensively treated
patients, nor did they incur more fractures over an average follow-up of
about five years.
"Lowering blood pressure using intensive treatment compared with
standard treatment did not result in an increased rate of falls or
fractures and, in fact, showed possible trends towards fewer fractures
in the intensively treated patients," explains Margolis. "Although
intensive blood pressure treatment to the low levels in ACCORD did not
lower cardiovascular events, our results and review of the literature
suggest a need to carefully reconsider current thinking about whether
antihypertensive treatment and blood pressure lowering increases risk
for falls and fractures."
Results in older versus younger patients were not different. No
evidence suggested that the risk of patients' falling varied over time,
although there were not enough fractures to determine if the short-term
risk might be higher at the beginning of intensive treatment. It is
important to note that subjects in this study were more closely
monitored than most patients in clinical practice; therefore, the
results may not completely reflect what would happen in actual practice.
