St Jude device lowers blood pressure in small study

(Reuters) – St Jude Medical Inc said on Monday its procedure that deadens nerves near the kidneys helped lower blood pressure in a small study of patients whose hypertension could not be controlled with drugs.

Patients in the study who were treated with the Enlightn renal denervation system saw an average reduction of 28 points in systolic blood pressure, which is the first number expressed in a reading, after 30 days. At six months, the 46 patients who received the treatment maintained an average systolic blood pressure reduction of 26 mmHg points.

The results were presented at the annual meeting of the American Heart Association in Los Angeles.

Patients enrolled in the study had an average blood pressure of 176/96 mmHg despite being treated with multiple medications to manage the condition. No serious side effects were reported, St Jude said.

Normal blood pressure is below 120/80 mmHg. Hypertension, or high blood pressure, is a reading above 140/90 mmHg.
