An analysis of results from randomized clinical trials reveals that more intensive hypertension treatment may be helpful for preventing or delaying strokes in older adults.

The analysis, which is published by Wiley in the Journal of the American Geriatrics Society, included nine trials involving 38,779 adults with an average age ranging from 66 to 84 years and follow-up times ranging from 2.0 to 5.8 years.

Investigators found that it took 1.7 years to prevent 1 stroke for 200 older persons treated with more intensive hypertension treatment.

For older adults with baseline systolic blood pressures below 150 mmHg, the time to benefit of more intensive hypertension treatment was longer than 1.7 years; for older adults with baseline systolic blood pressure above 190 mmHg, the time to benefit was shorter than 1.7 years.
