Secondary Outcome Measures :
  1. Change from baseline in office blood pressure measurement [ Time Frame: 30 days, 3 months, 6 months, 9 months, 12 months ]
  2. Change from baseline in ambulatory 24-hour blood pressure measurement [ Time Frame: 6 months, 12 months ]
  3. Change from baseline in renal artery dimensions [ Time Frame: 30 days ]
    Change in renal artery dimensions as measured by renal angiography, CT, or MRI
