Frequency and risk factors for worsening kidney function(WKF) in patients with heart failure at Shahid Madani hospital in 1398

Abstract

Heart failure is a clinical syndrome that results from heart muscle being unable to pump enough oxygenated blood to meet the body’s metabolic needs and is a chronic condition which significantly reduces quality of life.Worsening of kidney function may be one of prognostic factors for symptom exacerbation, increase in length of hospital stay and in-hospital mortality and treatment costs in patients with heart failure.This study is designed and performed to determine frequency and risk factors for worsening of kidney function among patients hospitalized with heart failure in shahid madani hospital. Materials and Methods:In the present study, data from patients hospitalized with heart failure during the year 1398 in shahid madani hospital were collected by medical records.Serum creatinine in admission and maximum serum creatinine , laboratory tests and para-clinical findings were collected through check lists.Collected data was analyzed using appropriate statistical analysis and SPSS-20 software. Results:347 patients were included.241 of them were men and 106 were women.117 of patients developed WKF during the hospital stay.230 did not develop this condition.14 of patients were expired in hospital and all of them had developed WKF.Mean for length of hospital stay for patients with WKF was 6/94 days and for patients without WKF was 6/03 days.1 year of increase in age was related with 1/01 of higher risk for WKF.Patients who used diuretics at home had lower risk for developing WKF.Mean for serum Na level in patients with WKF was 135/84 mEq/L compared to 136/91 for patients without WKF.12/82 percent of patients with WKF had diabetes in past medical history while 4/35 percent of other group had diabetes this finding was statistically significant.chance of developing WKF in patients with admission creatinine level lower than 1/5 was 2/25 times higher than patients with admission creatinine higher than 1/5.
