[Chronic kidney failure at subclinical stage in hypertensive patients in the cardiology department of the Gabriel TOURE university hospital].

Objective: This work aimed to describe the epidemiological, clinical, biological and ultrasound aspects of the subclinical renal failure in hypertensive patients in the department of cardiology of the Gabriel TOURÉ University Hospital of Bamako.
Patients and Methods: The study was cross-sectional and prospective from 1 January 2007 to 31 December 2007 in the cardiology department of the Gabriel Touré University Hospital. These were all patients who achieved at least the basic test for renal impairment such as serum creatinine, 24h proteinuria, renal ultrasound.
Results: Total of 114 patients with kidney failure without evocative clinical symptoms have been included, among them 60 men and 54 women, average age of 57 years. In the hypertensive population, the beginner to moderate chronic renal failure had a frequency of 12.9% (114/880), the sex ratio was 1.11 in favor of men. Patients aged less than 60 years were more numerous with a frequency of 61.5%. Dyspnea (38.6%), and headache (36.8%) were the main manifestations of the high blood pressure (HBP). Renal disease characterized by microalbuminuria was predominant compared to the macro-albuminuria: 25.5% versus 7%. Renal ultrasound was abnormal in 14.1% with a predominance of stage 0 (86%), stages 1 and 2 were each 7%, we have not found any stage 3.
Conclusion: Chronic renal failure is a frequent complication of the hypertension. Some biological tests are necessary for the diagnosis. Renal ultrasound remains a useful test for its assessment. The optimal treatment of high blood pressure is essential, as it not only reduces the overall cardiovascular risk of patients, but also slows or even stabilizes the worsening of renal function.
