ABSTRACT
Background:
Chronic kidney disease is a major health problem since it is associated with a high cardiovascular risk, total morbidity and mortality, increasing prevalence and high cost treatment.Aim:
To assess the frequency of chronic kidney disease among patients consulting in a cardiology clinic. Material andMethods:
Cross-sectional assessment of 649 patients attended at a cardiology clinic. Demographic, clinical, electrocardiographic, echocardiographic and laboratory variables were registered. Patients were considered to have a kidney failure when their estimated glomerular filtration rate was < 60 ml/min/1.73 m² according to the Modification of Diet in Renal Disease (MDRD) formula. Kidney failure was considered chronic if this alteration lasted ≥ 3 months and hidden when serum creatinine levels were normal.Results:
The frequency of kidney failure was 20.8% (28.4% in patients ≥ 65 years old). The mean age of patients with the disease was 71.5 ± 9.1 years and 52% were women. Eighty seven percent were in stage 3, 10% in stage 4 and 3% in stage 5. Among patients with kidney failure, in 114 (84%) it was chronic and in 28%, hidden. The latter was observed almost exclusively in women with creatinine levels of approximately 1 mg/dl. Hypertension (Odds ratio (OR) 4.2), age (OR 1.1), ventricular ejection fraction (OR 0.97) and low hemoglobin (OR 0.735) were the risk factors for kidney failure detected in the multivariate analysis.Conclusions:
The frequency of kidney failure (chronic or hidden) was high in this group of cardiologic patients. Most patients had a mild to moderate failure and the risk factors were hypertension, age, low ventricular ejection fraction and low hemoglobin levels.
