High-sensitivity troponin T and N-terminal-pro-BNP were shown in 2 important studies to help predict risk of stroke and embolic events in patients with atrial fibrillation.

In a proof-of-principle study, German researchers evaluated an affordable, accessible, and cost-effective way to help diagnose atrial fibrillation after ischemic stroke, with promising results.
