Background To determine the impact of heart failure (HF), with preserved or decreased left ventricular function (LVF), on outcome in patients with acute ischemic stroke (AIS). Methods We studied 503 unselected ischemic stroke patients. Poor outcome was defined as moderate-severe disability or death at 90 days. We analyzed the association between poor outcome and HF with preserved LVF or decreased LVF (systolic HF: ejection fraction lower than 50%). We tested this association adjusted by possible confounders in a logistic regression model. Results 89 patients (17.7 %) had HF; 49 patients (9.7%) with systolic HF, and 40 (8%) patients with HF and preserved LVF. HF with preserved LVF patients were older [79.4 (7.9) vs. 74.3 (10.4), p = 0.013],more likely to be women [p < 0.001,OR = 8.61, 95% CI (3.3-22.6)], and with lower current smoking habits [p = 0.018, OR = 8.77 (1.1-72.6)] than patients with systolic HF. 151 patients (30 %) had poor outcome. We found an independent association with initial stroke severity, systolic HF (adjusted OR = 3.01), HF with preserved LVF (adjusted OR = 2.52), thrombolytic treatment, statin pre-treatment (as protectors) and poor outcome. Conclusion Both forms of HF (with or without decreased systolic function) are associated with poor outcome in AIS.
