- Background and Purpose: Natriuretic peptides predict poor outcomes in cardiovascular disease. However, the knowledge of their relationship to stroke is limited and prospective studies from the general population are few. The purpose of this study was to explore the relationship between N-terminal pro-brain natriuretic peptide (NT-proBNP) and midregional pro-atrial natriuretic peptide (MR-proANP) plasma levels and the risk for ischemic stroke and its subtypes. Methods: NT-proBNP and MR-proANP were measured in fasting blood samples from 4,862 subjects (40.2% men, mean age 57.5 ± 6.0 years) without cardiovascular disease from the Malmö Diet and Cancer Study, a prospective, population-based study in Sweden. Incidence of ischemic stroke was monitored over a mean follow-up of 14.9 ± 3.0 years. Stroke cases were etiologically classified according to the TOAST classification. Cox proportional-hazards regression was used to study the incidence of stroke in relationship to NT-proBNP and MR-proANP. Results: During follow-up, 227 had a first-ever ischemic stroke (large-artery atherosclerosis, n = 35; cardioembolic stroke, n = 44; small-artery occlusion, n = 80; undetermined cause, n = 68). In the age- and sex-adjusted model, only NT-proBNP was associated with total ischemic stroke. This association was completely explained by an increased incidence of cardioembolic stroke. Adjusted for cardiovascular risk factors (age, sex, hypertension, diabetes, smoking, body mass index and low-density lipoprotein cholesterol), the hazard ratios (HRs, 95% confidence interval, 95% CI) for cardioembolic stroke were 1.00 (reference), 1.42 (0.34-6.00), 2.79 (0.77-10.12) and 5.64 (1.66-19.20), respectively, for the 1st, 2nd, 3rd and 4th quartiles of NT-proBNP. The corresponding HRs (95% CIs) for quartiles of MR-proANP were 1.00 (reference), 1.83 (0.55-6.14), 1.20 (0.33-4.34) and 3.96 (1.31-11.99), respectively. In total, 335 (6.9%) subjects were diagnosed with atrial fibrillation during follow-up. Among the cardioembolic stroke cases, 30% were diagnosed with atrial fibrillation before the stroke event and another 36% within 6 months after the stroke. Of the cardioembolic stroke cases with atrial fibrillation, 59% were in the top quartile of NT-proBNP, 69% in the top quartile of MR-proANP and 79% were either in the top quartile of NT-proBNP or in the top quartile of MR-proANP. Conclusion: High plasma levels of NT-proBNP and MR-proANP are associated with a substantially increased risk of cardioembolic stroke, but not with other subtypes of ischemic stroke. The results suggest that assessment of stroke risk, including electrocardiography, is warranted in subjects with high NT-proBNP or MR-proANP. © 2014 S. Karger AG, Basel.
