 (submitted: December 27, 2018)
Difference in annual eGFR decline (slopes) between dabigatran and warfarin patients [ Time Frame: 2 years ]
  • eGFR is to be calculated with CKD-EPI equation at baseline and at subsequent major visits.
  • for primary analysis only eGFR levels at one year and second year of treatment will be used. In case of one of values required for the analysis is missed LOCF (last observational carried forward) approach will be used

Descriptive Information
Brief Title  ICMJE RE-ELECT. Dabigatran vs Warfarin in AF Patients With T2D and CKD
Official Title  ICMJE RE-ELECT Study: "Randomized Evaluation of Changing Kidney Function Over a Time in Patients With Atrial Fibrillation, Concomitant T2D and Existing Chronic Kidney Disease Treated With Dabigatran or Warfarin for Stroke Prevention", № 1160.283
Brief Summary Kidney function in patients with atrial fibrillation (AF) is tending to decline over a time which is clearly demonstrated in clinical studies. Taking into account that renal impairment is a risk factor for stroke and its progression is associated with unfavorable prognosis it's clear that preserving kidney function should be considered as a one of priorities when choosing treatment strategies which is especially important in patients with existing chronic kidney disease or in patients who are under risk of its development. This is especially relevant for the patients with Diabetes mellitus and with Chronic kidney disease who can be considered as a group of risk of rapid progression of kidney function decline.
