Anticoagulation is a cornerstone of therapy for atrial fibrillation due to the fact it lowers the heightened chance for stroke in this population. Individuals with chronic kidney disease are also at increased risk for stroke, but the positive aspects of anticoagulation are less clear in this group, and anticoagulation is used much less often in AF sufferers who have CKD. Now, a large observational examine delivers some reassurance that anticoagulation in AF sufferers with CKD may possibly be helpful.
Researchers in Sweden analyzed information from far more than 24,000 survivors of acute myocardial infarction who had AF. In a paper published in JAMA, they report that a lot more than half (51.seven%) of this group had CKD (stage 3 or above). Much more than a fifth (21.eight%) of all patients have been taken care of with warfarin, and after 1 12 months of adhere to-up, these patients had a reduced price of death, MI, or stroke but no considerable increases in bleeding issues. The findings persisted following the researchers adjusted for differences amongst the groups. Severity of CKD did not impact the results.
In an accompanying editorial, Wolfgang Winkelmayer and Mintu Turakhia examine some of the limitations of the research, including “the central situation of confounding by indication for warfarin remedy.” They also point out that INR handle in Sweden is the very best in the world, so the outcomes of the study could not apply where warfarin is not optimally employed. In addition, they caution that the outcomes should not be generalized to AF sufferers who have not had an MI.
Nevertheless, they create, the review “provides the best evidence to date that vitamin K antagonists are associated with improved clinical outcomes and no substantial enhanced chance of bleeding in individuals with myocardial infarction and atrial fibrillation with superior CKD. These data support the use and continuation of warfarin treatment amid individuals with CKD with superb INR management.”
