  • Title: Microalbuminuria in essential hypertensives in treatment for hypertension.
    Author: Cruz HM, Cruzera AB, Cruz J.
    Journal: Rev Hosp Clin Fac Med Sao Paulo; 1997; 52(5):258-62. PubMed ID: 9595780.
    Abstract:
    Urinary albumin excretion (UAE) was evaluated in 26 subjects with essential hypertension and no diabetes (5 men, 21 women; 19 whites and 7 blacks), with creatinine clearance (Ccreat) > or = 75 ml/min/1.73 m2, in individualized treatment with various antihypertensive drugs. Clinical and laboratorial data were the following: mean age, 53 +/- 2 years (SEM); duration of hypertension, 14.9 +/- 2.2 years; body mass index (BMI), 26.8 +/- 0.7; arterial blood pressure, 142 +/- 4/89 +/- 3 mmHg; serum creatinine, 0.8 +/- 0.03 mg/dL; Ccreat, 99.3 +/- 3.8 ml/min/1.73 m2 and UAE, 9.3 +/- 1.5 micrograms/min. No significant difference was found when data were evaluated for gender and race. Microalbuminuria, defined as UAE > 13.9 micrograms/min, was found in 19% of the hypertensives (range: 16.3 to 28.1 micrograms/min). UAE correlated positively and significantly with systolic (r = 0.6309; P = 0.0005), diastolic (r = 0.4146; P = 0.0352), and mean blood pressure (r = 0.5000; P = 0.0093). The correlation between UAE and systolic pressure was stronger than with diastolic pressure. There was a positive and significant correlation between BMI and UAE values (r = 0.5623; P = 0.0028), and between BMI values with those of systolic (r = 0.5271; P = 0.0057) and mean blood pressure (r = 0.3930; P = 0.470). No correlation was found between UAE and age, duration of hypertension or Ccreat. Systolic, diastolic and mean blood pressures were significantly higher in microalbuminuric than in non microalbuminuric hypertensives. Obese hypertensives presented higher mean values of UAE, systolic, diastolic and mean pressures than non obese.
