Abstract
Background: The interaction between heart and kidneys has increased, and parts of the pathophysiological background for the cardiorenal syndrome have been established. This study aimed to determine the prevalence of Chronic Kidney Disease (CKD) among Heart Failure (HF) patients. Methods: This is a cross-sectional study included 1559 patients, who were admitted with a diagnosis of HF during the period from 1-March-2011 till 20-June-2019 at Madinah cardiac center. All patients were divided into five renal function categories based on the estimated glomerular filtration rate. Results: Of the total of 1559 patients, 67.2% were males, 51.3% were hypertensive, 56.1% were diabetic and 49.1% were anemic. About 9.8% of HF patients had stage I CKD, 29.6% had stage II, 41.9% had stage III, 15% had stage IV, and 3.9% had stage V. Patients with CKD were significantly had valvular heart diseases (p<0.001), history of ACS (p=0.002), rheumatic heart diseases (p=0.043), anemia (p<0.001), hypertension (p<0.001), diabetes mellitus (p<0.001), stroke (p=0.003) and smoking (p<0.001). Conclusion: About 9.8% of HF patients had stage I CKD, 29.6% had stage II, 41.9% had stage III, 15% had stage IV and 3.9% had end stage renal disease.
