Factors associated with cardiorenal syndrome in patients with decompensated heart failure

Objective: to identify cardiorenal syndrome (CRS) prevalence in patients with decompensated chronic heart failure (HF) and its association with sociodemographic and clinical data, admission fi ndings, mortality and length of hospital stay. Methods: a cross-sectional study with a quantitative approach. The sample consisted of 379 medical records of adult patients with a medical diagnosis of decompensated chronic HF admitted to a public hospital in the state of São Paulo, throughout 2015. Data collection occurred in 2016. Kidney failure was considered in patients with a previous diagnosis of chronic kidney disease (CKD) by glomerular fi ltration rate (GFR) <89 mL/ min/1.73 m 2 . Tests with a p value less than or equal to 0.05 were statistically signifi cant. Results: CRS prevalence was 54.1%, with 24.8% being type 1 and 29.3% being type 2. The main factors associated with CRS were: higher
