Introduction: Chronic kidney disease (CKD) is associated with poor outcome in patients with heart failure (HF), but little is known about the prognostic value of urine results in these patients. We therefore investigated the relationship between urine results and the prognosis of hospitalized patients with HF. Methods: We retrospectively reviewed the database of the Cardiovascular Center of Toranomon Hospital, Japan and enrolled 128 consecutive patients who admitted with their first presentation of acute decompensated HF. Urine results were available in 76 patients between discharge and the first visits. We assessed the predictive value of hematuria for one-year mortality in addition to the renal function among these patients. Results: Ten patients (13%) had microscopic hematuria (++ or more) between discharge and the first visits. One-year mortality of the patients with microscopic hematuria was higher than those without (P = .029). In multivariate analysis including estimated glomerular filtration rate at discharge, age, and left ventricular ejection fraction, the predictive value of hematuria for the mortality remained significant (P = .017). Conclusions: Microscopic hematuria could predict the prognosis in patients with heart failure after discharge.
