خطورة حدوث القصور الكلوي الحاد عند المرضى المقبولين في المشفى بسبب انكسار معاوضة قصور قلب احتقاني

This is an observational study based on hospital medical records of (96) patients admitted with a principal diagnosis of CHF. ARF is defined as an increase in serum creatinine of 0.5mg/dl compared to the admission value.Multiple elements are studied as possible indicators of ARF development. Mean serum creatinine is 1.71±1.15mg/dl, and calculated creatinine clearance is 57.2 ml/min. ARF has developed in 31 patients (32,29%), with a peak increase in serum creatinine by (0.5-3.83) mg/dl. An increase in serum creatinine is observed in (83.87%) of patients on days (4-6) of admission. ARF is associated with increased in-hospital mortality, morbidity, and prolongation of hospital stay. Risk factors for ARF include: increase serum creatinine on admission, hyponatremia, ACEI/ARB therapy, and diastolic dysfunction.
