Impaired exercise tolerance is associated with increased urine albumin excretion in the early stages of essential hypertension
2011
Background: Our aim was to investigate the relationship between impaired exercise capacity and albumin excretion level in the setting of never treated essential hypertension. Design and methods: For this purpose, 338 consecutive essential hypertensives (52 ± 8.5 years, 227 males, office BP = 148.6/96.1 mmHg) performed a negative for myocardial ischemia, maximal treadmill exercise testing and were classified based on the gender specific median value of the amount of metabolic equivalents (METs) achieved (10.1 ml/kg/min for women and 11 ml/kg/min for men) as fit ( n = 177) and unfit ( n = 161). All the participants underwent 24-h ambulatory BP monitoring, complete echocardiographic study inc…
Microalbuminuria and early endothelial activation in essential hypertension
2006
We hypothesized that in essential hypertensive patients (EHs), plasma levels of pro-atherogenic adhesion molecules would be increased and related with urine albumin excretion (UAE). Thus, this study was aimed at evaluating biochemical markers of endothelial activation and their relationship with UAE in a group of patients with uncomplicated EH. In basal condition soluble forms of adhesion molecules intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1, as well as 24-h UAE were assayed. One hundred patients with essential hypertension and no diabetes or ultrasonographic evidence of atherosclerosis were included in the study. Seventy normotensive healthy subjec…
Microalbuminuria, renal dysfunction and cardiovascular complication in essential hypertension
1996
To evaluate the prevalence of microalbuminuria (albumin excretion rate, AER) in a wide hypertensive population, and to evaluate any relationship with cardiovascular damage and renal dysfunction.A transversal study.In 383 hospitalized Caucasian essential hypertensives (198 men, 185 women) of mean age 44 +/- 0.5 years and mean clinic blood pressure 170.3 +/- 0.95/ 103.4 +/- 0.47 mmHg, metabolic parameters, serum creatinine level (Cs), creatinine clearance rate (Ccs), 24 AER and plasma renin activity (PRA) were measured. Furthermore, each patient underwent 24 h ambulatory blood pressure monitoring (ABPM) and echocardiography to measure left ventricular mass, which was indexed both by body surf…
Increase in Nocturnal Blood Pressure and Progression to Microalbuminuria in Type 1 Diabetes
2002
Patients with type 1 diabetes mellitus and microalbuminuria often have elevated blood pressure while they are asleep, but it is not known whether the elevation develops concomitantly with microalbuminuria or precedes it.We monitored 75 adolescents and young adults who had had type 1 diabetes with normal urinary albumin excretion and blood pressure for more than five years. Ambulatory blood-pressure monitoring was used to assess blood pressure at the initial evaluation and about two years later, at which time all subjects had normal urinary albumin excretion. Subsequently, subjects were monitored for the development of microalbuminuria.Microalbuminuria developed in 14 subjects, whereas the o…
Microalbuminuria fractional clearance and early renal permselectivity changes in essential hypertension.
1992
In order to verify if, in essential hypertension (EH), the microalbuminuria (AER) increase could be due to hemodynamic modifications or to glomerular structural changes, in 15 essential hypertensives (EHs) with 24-hour AER16 micrograms/min and in 15 EHs with 24-hour AERor = 16 micrograms/min, the day- and nighttime behavior of creatinine clearance (Ccr), as well as AER clearance (AER-C) and fractional clearance (AER-FC), and behavior of blood pressure (BP) was evaluated. Patients with 24-hour AER16 micrograms/min showed significantly higher values of 24-hour and daytime Ccr than the other group of EHs, while during the night period, there were no significant differences between the two grou…
Prevalence of type 2 diabetes among patients with hypertension under the care of 30 Italian clinics of hypertension: results of the (Iper)tensione an…
2008
BACKGROUND AND PURPOSE Hypertension is known to be highly prevalent among patients with diabetes and associated with an increased risk of cardiovascular damage. In contrast, relatively few investigations have addressed the prevalence of diabetes among patients with hypertension. The purpose of the present study was to examine the prevalence of type 2 diabetes, the effectiveness of hypertension and diabetes control and the association with other cardiovascular risk factors and previous cardiovascular diseases in a cohort of patients with hypertension referred to 30 hospital outpatient clinics for the treatment of hypertension. METHODS AND PATIENTS Patients were considered as having diabetes …
Losartan reduces microalbuminuria in hypertensive microalbuminuric type 2 diabetics.
2001
Background. The aim of the present study was to assess the antialbuminuric effect of losartan in a large number of hypertensive type 2 diabetics. Methods. This was a 6-month, open-label, prospective and multicentre study. A total of 422 patients with type 2 diabetes who were hypertensive [sitting systolic blood pressure (SBP) > 140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg] and microalbuminuric [urinary albumin excretion (UAE) 30-300 mg/day] were eligible for the study. After a 2-week run-in period, patients were placed on losartan 50 mg once a day. If the BP did not reach the desired goal (<140/90 mmHg) after a 4-week period, the losartan dose was doubled. In the absence of contr…
Average real variability of 24-h systolic blood pressure is associated with microalbuminuria in patients with primary hypertension.
2015
Limited and conflicting data are available about the association between short-term blood pressure (BP) variability and urinary albumin excretion rate (uAER). The objective of our study was to analyze the relationships between microalbuminuria (MAU), defined as an uAER between 20 and 200 μg min(-1), and short-term BP variability (BPV), assessed as average real variability (ARV), weighted s.d. of 24-h BP and as s.d. of daytime and night-time BP. The study population consisted of 315 untreated essential hypertensives with normal estimated glomerular filtration rate (>60 ml min(-1) per 1.73 m(2)), who underwent 24-h ambulatory BP monitoring and 24-h uAER determination. MAU was detected in 82 (…
