Incidence and impact of cardio-renal syndrome type 1 in patients with heart failure

Abstract

Acute renal failure is detected in more than a third of patients with heart failure, thus defining the acute cardio-renal syndrome. Kidney failure is a risk factor that prolongs hospital stay for heart failure patients and likely leads to treatment failure and recurrent episodes of heart failure. The aim of this study is to assess the incidence and profile of heart failure patients with type 1 cardio-renal syndrome. Methods :This is a descriptive retrospective study, having included patients admitted for an attack of heart failure complicated by acute renal failure, during the period extending from January 2020 to December 2022 (2 years) at level of the cardiology department of the CHU-Tlemcen. Results :A total of 71 patients: 67.60% of men and 32.40% of women, with an average age of 67 ± 14 years were admitted for a heart failure episode complicated by acute renal failure in a period of 2 years. The most affected age group was that of patients over 70 years old (46.48%). The average length of hospitalization was 15 days with a death rate of 29.58%. Conclusion :The association of heart failure and renal failure has a poor prognosis because it often requires modification of the therapeutic strategy recommended in patients with heart failure. Kidney failure is a risk factor that prolongs the length of hospitalization for heart failure patients.
