Acute Kidney Injury during Decompensated Heart Failure in Cardiology of Ignace Deen University Hospital Center, Conakry

Introduction: Heart failure (HF) is a significant public health issue.The objective of this study was to investigate acute kidney injury in the cardiology department.Material and Methods: We conducted a cohort study in the cardiology department over a period of 6 months, from January 1 to June 30, 2024.We included all patients hospitalized for decompensated heart failure (HF) whose diagnosis of acute kidney injury (AKI) was confirmed by a sudden increase in creatinine associated with a urinary anomaly according to the KDIGO classification.The data was collected using SPSS version 29.0.Result: Of a total of 112 patients during the study period, 36 patients (32.14%) developed AKI, while 76 patients (67.86%) had normal creatinine levels.The mean age was 36.77 12 years, with a range from 16 to 85 years.There were 19 (52.78%) men and 17 (47.22%)women, the sex ratio was 0.89.There were 23 (63.89%) cases of global heart failure and 8 cases of left heart failure (22%), with creatinine levels elevated in 36 patients.Acute kidney injury (AKI) was observed in 26 patients (72.22%) who were at stage 1, then 8 (19%) patients at stage 2, and 3 (9%) at stage 3. Conclusion: AKI is common during decompensated heart failure; diagnosis and management should be early to improve cardiac complications.
