Background and Objective: The aim of this study was to assess the relationship between central blood pressure and vascular damage., Patients and Methods: This cross-sectional study involved 393 never treated hypertensive patients (166 women). Clinical blood pressure (BP), 24h blood pressure (BP24h) and central blood pressure (CBP) were measured. Vascular organ damage (VOD) was assessed by calculating the albumin/creatinine ratio (ACR), wave pulse pressure velocity and echocardiographic left ventricular mass index (LVMI)., Results: Patients with VOD had higher values of BP, BP24h, and CBP than patients without ACR. When comparing several systolic BP, systolic BP24h had a higher linear correlation with CBP (Z Steiger test: 2.26; P=.02) and LVMI (Z Steiger test: 3.23; P=.01) than PAC. In a multiple regression analysis corrected by age, sex and metabolic syndrome, all pressures were related with VOD but systolic BP24h showed the highest correlation. In a logistic regression analysis, having the highest tercile of systolic BP24h was the stronger predictor of VOD (multivariate odds ratio: 3.4; CI 95%: 2.5-5.5, P=.001)., Conclusions: CBP does not have more correlation with VOD than other measurements of peripheral BP. Systolic BP24h is the BP measurement that best predicts VOD., (Copyright © 2014 Elsevier España, S.L.U. All rights reserved.)

Introduction: We performed this study to compare the achievement of lipid targets as well as the change on C reactive protein (CRP) values of two different strategies, the combination of ezetimibe plus statins compared to the doubling of the previous statin dose., Methods: Retrospective longitudinal study of 111 dyslipidemic patients, treated with statins, whose cholesterol values were still elevated. In 59 patients the previous statin dose was doubled, in 52 patients ezetimibe was added to the statin. Differences on lipid parameters and CRP were measured., Results: Patients treated with the association of ezetimibe plus statins obtained a higher reduction of LDL-cholesterol levels (38% vs. 18.1%, p<0.001), compared with those doubling the statin dose. A reduction on CRP values was observed only in patients on combined therapy (22.5%; p<0.005), CRP change was not related to lipids variation. More patients with high coronary risk treated with ezetimibe plus statin, reached lipid goals (LDL<100 mg/dl) compared to those whose statin dose was doubled (47% vs 19%; p<0.001) and the same happened on very high coronary risk patients (LDL<70 mg/dl) (43% vs 2%; p<0,001). More patients in the group ezetimibe plus statin achieved the combined target lipid control and CRP<3 mg/l (19% vs. 3%, p=0.002)., Discussion: Combination treatment of ezetimibe with statins on high coronary risk patients showed a better achievement of LDL-cholesterol goals with a reduction of CRP values., (Copyright (c) 2008 Sociedad Española de Calidad Asistencial.

Introduction and Objectives: The aim of this study was to evaluate the use of spironolactone and doxazosin as treatment for patients with resistant hypertension., Methods: This retrospective study involved 181 outpatients with resistant hypertension (defined as a failure of blood pressure [BP] control despite treatment with three drugs, one of which was a diuretic) who received additional spironolactone (n=88) or doxazosin (n=93)., Results: Mean systolic BP in the spironolactone group fell by 28 mmHg (95% confidence interval [CI], 24-32 mmHg; P< .001) and mean diastolic BP fell by 12 mmHg (95% CI, 9-14 mmHg; P< .001). The corresponding falls in the doxazosin group were 16 mmHg (95% CI, 13-20 mmHg; P< .001) and 7 mmHg (95% CI, 5-9 mmHg; P< .001), respectively. The decrease was significantly greater with spironolactone for both systolic (P< .001) and diastolic (P=.003) pressures. At the end of follow-up, 30% of all patients had achieved BP control, with control being more frequent with spironolactone (39%) than doxazosin (23%; P=.02). Multivariate logistic regression analysis showed that the only factors that significantly influenced the achievement of BP control were diabetes (odds ratio=0.17; 95% CI, 0.08-0.39; P< .001) and baseline systolic BP <165 mmHg (odds ratio=2.56; 95% CI, 1.11-5.90; P=.03)., Conclusions: In patients with resistant hypertension, the addition of either spironolactone or doxazosin resulted in a significant decrease in BP, though the decrease appeared to be greater with spironolactone. The presence of diabetes complicated BP control.

Background and Objective: The aim of the study was to assess the effect of adding spironolactone to hypertensive resistant (HTR) patients and characterize those who respond effectively., Patients and Method: Observational retrospective study on outpatients with HTR (being treated with at least 3 drugs at full doses, one of these being a diuretic) not achieving blood pressure (BP) goals, with normal creatinine values (< 1.6 mg/dl for males and < 1.4 mg/dl in women)., Results: A total of 95 patients (70% male), average (standard deviation) age of 66 (12) years (40% diabetics), were treated with spironolactone during 4 months (range: 2-13). Mean systolic and diastolic BP fell from 170/86 (20/14) mmHg, by 29/12 mmHg (95% confidence interval [CI], 25 to 33/10 to 14 mmHg; p = 0.001). At the end of follow-up, 38% of all patients achieved the goal of BP control. Initial systolic BP < 165 mmHg (odds ratio [OR] = 3,97; 95% CI, 1.52-10.37; p = 0.005), and diabetes (OR = 0.33; 95% CI, 0.13-0.86; p = 0.02) were the only independent factors related to BP control in a logistic regression analysis., Conclusions: The addition of spironolactone effectively lowers BP in patients with HTR treated with 3 drugs. BP control is more difficult to achieve in diabetics.

Background and Objective: The aim of the study was to assess the relationship of cystatine C to other cardiovascular risk factors in hypertension., Patients and Method: Cross-sectional study in hypertensive outpatients with normal creatinine values (< 1.6 mg/dl for males and < 1.4 mg/dl for women). Cystatin C was analyzed by immunonephelometry., Results: 283 patients (47% male) were evaluated. Cystatin C values were 0.65 (0.27) mg/l (median, intercuartile range, percentile 70 = 0.76 mg/l), and were correlated to the estimated glomerular filtration rate (GFR) (ml/min/1.73 m(2)), C reactive protein, and urinary albumin excretion (UAE). In multiple regression analysis the GFR was the most significant factor and explained 38% of cystatine C variability. GFR, (odds ratio [OR] = 5.84; 95% confidence interval [CI], 2.27-15.03; p < 0.001), age (OR = 1.05; 95% CI, 1.02-1.08; p < 0.001), and CRP (OR = 2.03; 95% CI, 1.07-3.84; p = 0.03), but not UAE > or = 30 mg/24 h, were independent factors related to the presence of high levels (> 0.76 mg/l) of cystatine C in a logistic regression analysis. 58% of patients with UAE > or = 30 mg/24h had cystatin C values < 0,76 mg/l., Conclusions: In hypertensive patients, the GFR is the most important factor related to cystatine C values. Increased levels of cystatine C do not correspond to UAE augmentation.
