The American Society of Hypertension 28th Annual Scientific Meeting and Exposition

The annual meeting of the American Society of Hypertension was held from May 15 to 18 in San Francisco and attracted more than 1,700 participants from around the world, including clinicians, academicians, allied health professionals, and others interested in high blood pressure management. The conference highlighted recent advances in the prevention, detection, and treatment of hypertension and related cardiovascular conditions as well as in the pathobiology of hypertension.

In one study, Teemu Niiranen, M.D., of the National Institute for Health and Welfare in Helsinki, and colleagues evaluated the optimal number of home blood pressure measurements in relation to cardiovascular outcomes.

"We found that 14 point measurements are a good number of measurements to assess blood pressure. In addition, after the first measurement period of 14 points in time, we found that six measures over a three-day period is sufficient for accurate blood pressure assessment," said Niiranen.

Currently, the recommendations on the optimal home blood pressure measurement schedule are not fully evidence based.

"It is important to teach patients how to measure their own blood pressure based on specific recommendations," added Niiranen. "Unified international recommendations are needed and our results could be implemented in future guidelines."

In another study, Alok Gupta, M.D., of the Pennington Biomedical Research Center in Baton Rouge, La., and colleagues found that patients who lost weight saw a decrease in their blood pressure. The more weight a patient lost, the higher the drop in blood pressure.

"Being overweight and obese is associated with an increased risk for prehypertension and hypertension. However, losing weight can decrease this risk for prehypertension and the propensity of prehypertension to convert to hypertension," said Gupta. "Lifestyle changes, including 150 minutes of exercise per week and reduction of daily calories, can help to reduce weight and thus blood pressure. Overall, the greater the percentage of weight loss, the higher the magnitude of blood pressure reduction."

Gupta disclosed a financial relationship with VIVUS, the manufacturer of Qsymia.

Pablo Pergola, M.D., of Renal Associates in San Antonio, and colleagues found that lowering systolic blood pressure to a target less than 130 mm Hg in patients with recent lacunar stroke was safe and effective for reducing the risk of intracerebral hemorrhage and stroke.

"Treatment of hypertension, the single most powerful risk factor for stroke, is proven to prevent stroke. Although lacunar strokes account for fewer than 25 percent of brain infarcts, no clinical trial has focused on this stroke subtype. Optimal target levels of blood pressure control to prevent stroke recurrence in patients with cerebral small vessel disease have not been established," the authors write.

The investigators randomized 3,020 patients with magnetic resonance imaging-proven symptomatic lacunar infarcts to two targets of systolic blood pressure, one between 130 and 149 mm Hg (higher) and another to less than 130 mm Hg (lower). The investigators found that the rates of recurrent stroke and intracranial hemorrhage were lower among those in the "lower" blood pressure group compared to the "higher" blood pressure group.
