Restoring a steady heartbeat within 8 weeks of a stroke was linked to 44% fewer second strokes

After a stroke, many older patients also have atrial fibrillation — an irregular heartbeat that lets clots form and travel to the brain. A Kyoto University study of 14,355 patients, average age 83, published in the journal Neurology, asked whether acting fast on the rhythm itself changes what happens next. People whose rhythm was restored within eight weeks — with medicines, a catheter procedure or a small electric shock — had an 8% risk of another stroke or clot over five years, against 14% without early control: a 44% lower risk, alongside 28% lower risk of death. It is an observational link, not proof, but it points doctors toward the clock: sooner may be safer.
