Fixing faulty heart rhythms may help kidneys filter better
Working to lower blood pressure, cholesterol, and blood sugar and to ease inflammation definitely helps the heart. It is also good for the kidneys. Now, Japanese researchers have found that treating atrial fibrillation (AF), the fast and uncoordinated beating of the heart's upper chambers, may improve the kidneys' filtering abilities.
In a study, 386 people with AF and mildly reduced kidney function received a catheter-based procedure called ablation to restore normal atrial beats. The tip of the catheter destroys (ablates) small patches of tissue in the left atrium that generate the electrical signals that incite AF (see illustration).
