The purpose of this study is to evaluate the diagnostic value of serum NT - proBNP in stroke associated with nonvalvular atrial fibrilltion.
All included in the cases in 7 days of blood samples, the detection of serum NT - proBNP.Through the single factor analysis to determine the serum NT - proBNP central source sex stroke prediction values.
- Observation: Case Control
- Perspective: Prospective
- Sampling: Probability Sample
18 ≤ Age ≤ 85; meet the clinical diagnostic criteria for acute ischemic stroke; onset within 24 hours at the same time more than one hour; it was diagnosed with experiential doctor.
