Prehypertension is a considerable health risk

Physician Practice Advisor, November 12, 2004

Prehypertension-an elevation in blood pressure that is a risk factor for heart attack, heart failure, stroke, and kidney disease-is estimated to be responsible for 9.1% of U.S. deaths, 6.5% of nursing home stays, and 3.4% of hospital stays each year for people ages 25 to 74, according to new research funded by the Agency for Healthcare Research and Quality (AHRQ).

Prehypertension is defined as having a systolic blood pressure between 120 mmHg and 139 mmHg; residual hypertension means continuing to have a systolic pressure of 140 mmHg or higher despite treatment.

The researchers found that women between the ages of 65 and 74 would benefit the most from elimination of prehypertension and residual hypertension. Hospital admission rates among women could drop by almost 150 admissions per 10,000 women in this age group. Men also show substantial reductions in risk. Hospital admission rates could drop by 85 admissions per 10,000 for men ages 45-64 and by 62 admissions per 10,000 for men 65-74.
