简要总结

The purpose of this study is to assess the efficacy of two different treatment regimens for treating resistant hypertension previously uncontrolled with at least 3 antihypertensive treatments. The study hypothesis is that these two regimens (one based on increasing diuretics and the other based on increasing renin angiotensin system blockage) may not differ in terms of efficacy.

详细描述

Tested hypothesis: For essential resistant hypertension, a new regimen based on intensive RAS blockage is non inferior to the recommended regimen based on intensive sodium depletion.

Primary objective: To demonstrate non-inferiority (i.e difference between the two regimen less than 5 mmHg for the mean day-time SBP at week 12)

  • One treatment arm including irbesartan 300 mg, hydrochlorothiazide (HCTZ) 12.5mg, amlodipine 5 mg, ramipril 10mg and bisoprolol 10 mg
  • One treatment arm including irbesartan 300 mg, HCTZ 12.5mg, amlodipine 5 mg, spironolactone 25 mg, furosemide 40 mg and amiloride 5 mg.

Secondary objectives:

  • To assess clinical and biological safety and efficacy of these regimen
  • To evaluate predicted factors of controlled or uncontrolled BP
  • To evaluate compliance to treatment
  • To compare the cost of the different strategies
  • To compare the two strategies in terms of endothelial function and left ventricular diastolic filling
