Kidney stenting lowers the blood pressure in patients who have severe hypertension, a new study has indicated.
A trial published in the journal Catheterization and Cardiovascular Interventions found that patients who suffered from uncontrolled renovascular hypertension experienced significant improvements in their blood pressure when a renal artery stent had been used.
Furthermore, patients who initially exhibited the highest levels of hypertension were seen to experience the most dramatic reduction in blood pressure following the treatment.
Renal artery stenoisis (RAS) - the narrowing of the arteries to the kidney - is mainly due to a build-up of fat and cholesterol along the artery walls, causing high blood pressure and kidney damage.
At the start of the study, the mean systolic blood pressure of participants stood at 162 mm Hg, and nearly 70 per cent of patients were taking three or more medications to control their blood pressure.
The success rates for the trial device, procedure and clinical outcomes stood at 96 per cent, 99 per cent and 98 per cent respectable.
Furthermore, freedom from major adverse events such as death, kidney removal or embolism causing renal injury, stood at 95 per cent.
