Plasma Concentrations of Brain Natriuretic Peptide in Patients with Acute Ischemic Stroke

233 participants including 88 patients with cerebral infarction (CI) (27 with atrial fibrillation [Af], 61 without Af), 59 with essential hypertension, 44 with spontaneous intracerebral hemorrhage, 22 with asymptomatic Af, and 20 age- and sex-matched healthy volunteers.

Measurement of plasma brain natriuretic peptide (BNP) concentrations.

Healthy volunteers and patients with essential hypertension, spontaneous intracerebral hemorrhage, or asymptomatic atrial fibrillation.
