Background: This study aimed to identify the association between long term functional outcomes and acute ischemic stroke (AIS) in patients with heart failure (HF) in Japan and whether 1-year event risks can be related to these patients.
Methods and Results: This was a prospective observational study, and 651 patients registered in the Tokyo Women’s Medical University Stroke Registry were classified into the HF and non-HF groups. Functional outcome at 1 year after stroke onset was defined as either good (modified Rankin Scale [mRS] score of 0–2) or poor (mRS score of 3–6). The primary outcome was a composite of major adverse cardiovascular events (MACE), including non-fatal stroke, non-fatal acute coronary syndrome, and vascular death. Patients with HF had a higher poor functional outcome rate at 1 year than those without HF (54.7% vs. 28.2%, P<0.001). Multivariate logistic regression analysis also demonstrated the prevalence of HF was an independent predictor of an mRS score of ≥3 at 1 year after stroke onset (odds ratio, 1.05; 95% confidence interval, 1.00–1.10; P=0.036). Furthermore, patients with HF tended to have a higher risk of MACE and all-cause mortality than those without HF.
Conclusions: AIS patients with HF were associated with poor functional outcome at the 1-year follow up. Further multicenter studies involving a larger number of patients are warranted to verify these results.
