The aim: To examine the association of hypertensive mediated target organ damage with blood pressure visit-to-visit variability in Ukrainian rural dwellers with uncomplicated hypertension. Material and methods: The cross-sectional study enrolled 160 adult males with uncomplicated primary hypertension (mean age 50±6 yo). We analyzed office systolic and diastolic blood pressure levels, obtained at four consecutive visits. We used standard deviation (SD) value to assess blood pressure visit-to-visit variability. The patients were referred to the group with high (n=82; 51.3%) vs low (n=78; 48.7%) blood pressure variability (HBPV, LBPV). Results: HBPV patients were characterized by higher left ventricular myocardial mass indexed to height 2.7: median, interquartile range: 70.9 (61.3-78.2) vs 50.9 (44.9-54.4) g/m2.7, respectively p<0.001. The cases of severe left ventricular hypertrophy prevailed in HBPV group (vs LBPV): 68% vs 5%, respectively, p<0.001. HBPV group was characterized by larger common carotid artery intima-media complex thickness, advanced hypertensive retinopathy, higher urine albumin/creatinine ratio value and worse kidneys’ glomerular filtration rate. The obtained results might be helpful in the context of global monitoring of vulnerable high risk population of hypertensive rural males. Conclusions: The HBPV in rural hypertensive males was associated with more pronounced target organ damage. Further regional research on the various clinical aspects of hypertension, including blood pressure variability, might be useful in extending the existed evidence on prevention of hypertension-related complications.

The overall goal of this study was to determine race/ethnic differences in the associations between renal ET-1 and indices of blood pressure-related target organ damage in healthy adolescents. The subjects ranged in age between 15-19 years, had no history of any disease, and were not on any prescription medications. The 92 subjects consisted of 48 Caucasians (CA) and 44 African-Americans (AA). The two groups were similar with respect to height, weight, body mass index, blood pressure, ET-1), albumin excretion rate (AER), and left ventricular mass). Results: The CA’s were slightly older 17±1 v 16±1 (p=.02). The protocol was preceded by a 3 day self-selected sodium controlled diet of 250 mEq/day day which the subject picked up each day. The test day began with an echocardiogram for the assessment of left ventricular mass. Next, the subjects were seated for 60 minutes of rest during which the subjects consumed 200 ml of water. This was followed by the collection of a urine sample for the measurement of ET-1 and AER. Overall, ET-1 excretion was correlated with AER (r=.278), LV mass/ht 2.7 (r=.341), and systolic blood pressure (SBP; r=.365; p=.01 for each). The significant overall correlations were the result of significant correlations in AAs for AER (r=.344; p=.05), LV mass/ht 2.7 (r=.520; p=.01), and SBP (r=.645; p=.01) which were not apparent in CA’s. These findings suggest urinary ET-1 contributes to the development of BP-related target organ damage in AA youths prior to the development of increases in blood pressure.

Abstract Background Blood pressure variability (BPV) has been associated with development, progression and severity of cardiac and vascular organ damage and with an increased risk of cardiovascular events and mortality, independently adding to cardiovascular risk, over and above the contribution of elevated mean BP levels. We aimed to explore any correlation between differences in BPV and target organ damage indices (TOD) in hypertensive patients three years after medical treatment initiation. Methods At baseline and before medical treatment initiation, we measured 24h average SBP and DBP as well as 24h systolic BPV after 24h ambulatory blood pressure monitoring (ABPM) in newly diagnosed and never treated hypertensive patients (n=171, mean age=52+12 years, 110 males, 24h average SBP/DBP=138+10/87+9 mmHg, 24h systolic BPV=15+3) who were also subjected to arterial stiffness by carotid-femoral pulse wave velocity (PWV), left ventricular hypertrophy by left ventricular mass index (LVMI) and coronary flow reserve (CFR) estimations. All the above tests were repeated approximately three years later after treatment initiation. Results Patients were characterized as controlled (n=113, mean age=54+12 years, 62 males, 24h average SBP/DBP=118+6/71+6 mmHg) or non-controlled hyperensives (n=58, mean age=48+11 years, 48 males, 24h average SBP/DBP=133+8/83+7 mmHg) based on ABPM results three years later (controlled BP=24h average BP<130/80 mmHg). In the whole population, 24h average SBP/DBP, systolic BPV (p<0.001) and LVMI (p=0.01) were decreased while systolic BPV difference was related with LVMI difference (r=0.27, p<0.001). In controlled hypertensives, 24h average SBP/DBP, systolic BPV (p<0.001) and LVMI (p=0.02) were decreased while systolic BPV difference was related with LVMI difference (r=0.35, p<0.001). In non-controlled hypertensives, 24h average SBP (p=0.001), DBP p<0.001) and systolic BPV (p=0.04) were decreased while PWV was increased (p=0.03) and no correlations were found between systolic BPV and TOD. Correlation between BPV and LVMI Conclusions It seems that antihypertensive-induced systolic BPV improvement relate with cardiovascular risk decrease occur only in the setting of blood pressure treated within normal limits and confirmed by ABPM. Our study confirms that left ventricular mass between other TOD primarily improves due to successful antihypertensive treatment.

Abstract Background To investigate the relationships of plasma renin, angiotensin, and aldosterone levels to blood pressure variability and target organ damage in children with essential hypertension. Methods A case-control study was conducted on 132 children diagnosed with essential hypertension(103 males and 29 females with the mean age of 11.8 ± 2.4 years). The plasma RAAS levels were measured using the enhanced chemiluminescence method, the ambulatory blood pressure was monitored for 24 h, and then the average real variability (ARV) was calculated. Data on indicators were used for assessing cardiac and renal damages. The correlations of plasma renin, angiotensin, and aldosterone (RAAS) levels to blood pressure variability (BPV) and target organ damage (TOD) were studied. A comparison between the groups was conducted using SPSS 20． Results Among the 132 children, 55 cases had target organ damage. The 24-h ARV and the daytime ARV of the systolic blood pressure of the high angiotensin II (AT II) group was significantly higher than that of the normal AT II group (t = 2.175, P = 0.031; t = 2.672, P = 0.009). Plasma AT II and aldosterone levels were significantly associated with the left ventricular mass index (r = 0.329, P= 0.0001; r = 0.175, P = 0.045). Linear regression analysis showed that AT II [ β± s.e.= 0.025±0.006, 95% CI ( 0.013–0.038), P = 0.0001] and aldosterone [ β± s.e.= 0.021±0.007, 95% CI( 0.008–0.034), P = 0.002] were risk factors for LVH. Conclusions The AT II level in children with essential hypertension affected the variability of the 24-h and the daytime SBP. Plasma AT II and aldosterone levels were associated with cardiac damage. Results from this study indicated that AT II and aldosterone are risk factors for LVH in childhood hypertension and are of great significance for improving the clinical prognosis of pediatric patients with hypertension.

Abstract Background: Blood pressure is an important and modifiable cardiovascular risk factor. Ambulatory blood pressure monitoring (ABPM) provides valuable prognostic information in patients with chronic kidney disease (CKD), yet little is known about the association of various types of BP measurements with target organ damage (TOD) in patients with primary glomerular disease. The goal of this study was to investigate whether ambulatory blood pressure is better associated with TOD than clinic blood pressure in patients with primary glomerular disease. Methods: 1178 patients with primary glomerular disease were recruited in this cross-sectional study. TOD were assessed by the following 4 parameters: left ventricular mass index (LVMI or LVH, left ventricular hypertrophy), estimated glomerular filtration rate (eGFR<60ml/min/1.73m 2 ), albumin-to-creatinine ratio (ACR≥30mg/g) and carotid intima-media thickness (cIMT) or plaque. Receiver operating characteristic (ROC) curve and multivariate logistic regression analyses were used to evaluate the relationship between ambulatory or clinic systolic blood pressure (SBP) indexes and TOD. Results: Among 1178 patients (mean age, 39 years,54% men), 116, 458, 1031 and 251 patients had LVH, eGFR < 60 ml/min/1.73m 2 , ACR≥30mg/g and cIMT≥0.9mm or plaque respectively. Area under ROC curves for TOD in ambulatory SBP, especially nighttime SBP, was greater than that in clinic SBP ( P <0.05). Multivariate logistic regression analyses showed that 24h SBP, daytime SBP and nighttime SBP were significantly associated with LVH, eGFR<60 ml/min/1.73m 2 and ACR≥30mg/g after adjustment for clinic SBP, while the association of clinic SBP was attenuated after further adjustment for nighttime SBP. Conclusions: Ambulatory blood pressure, especially nighttime blood pressure, is superior to clinic blood pressure in estimating TOD in patients with primary glomerular disease.
