Background/Introduction
The clinical importance of a hypertensive response to exercise (HRE) in subjects with high normal blood pressure (BP) is not fully elucidated, while sympathetic overactivity followed by arterial stiffening are linked with development of hypertension (HTN).
Purpose
The aim of this study was to assess the relation of HRE with sympathetic drive as assessed by muscle sympathetic nerve activity (MSNA) and arterial stiffness in subjects with high normal BP who developed hypertension in a 3 year follow up.
Methods
100 subjects with high normal office BP [systolic BP=130-139 mmHg and diastolic BP=85-89 mmHg] underwent a treadmill exercise stress test. Arterial stiffness was evaluated based on carotid to femoral pulse wave velocity (PWV). Sympathetic drive was assessed by MSNA levels. Follow up was every 6 months for 3 years, where BP was measured at both office (OffBP) and ambulatory blood pressure monitoring (ABPM). All participants offered lifestyle advises. Endpoint was development of HTN diagnosed either from OffBP or from ABPM. Then they were divided into Group I: those developed HTN and Group II: those remained normotensive.
Results
Mean age 54±8 years, 42 males, baseline offBP: 132/82 mmHg, ABPM: 122/76 mmHg). Out of them, 50 subjects developed HRE (BP ³210mmHg in men and ³190 mmHg in women) and 40 HTN. Group I developed higher HRE (75% vs. 13%, p=0.026), higher levels of PWV (8.35 vs 7.5 m/sec, p=0.043) and MSNA levels (37 vs. 31 bursts, p=0.04), while did not differ at their metabolic profile. Echocardiographically left ventricular mass index did not differ statistically as E/A ratio of mitral valve inflow (0.92 vs 1.05, p=0.034). Those who developed HTN was related to night systolic BP from ABPM (116 vs 112 mmHg, p<0.04), as also to intermediate stage intervals of 3 min (160 vs 147 mmHg, p=0.068) and 6 min (181 vs 164, p=0.035) of Bruce protocol. A novel metric, the SBP/MET-slope [(peak SBP—resting SBP)/(peak MET-1)] found to add crucial information. Regarding those who developed HTN, SBP/MET-slope was higher in all stages till peak exercise (stage 1: 6.25 vs 4.25, stage 2: 7.6 vs 5.3, peak: 7.22 vs 5.1, p=0.035). It was noticed that they performed a higher exercise capacity (10 vs 11.5 METs) and additionally differ significantly in their maximal heart rate (HR) at peak exercise (154 vs 164, p=0.001).
Conclusion
In subjects with high normal BP, a HRE, the intermediate BP intervals along with the SBP/MET-slope, identifies a state of systemic vascular resistance, arterial stiffening and sympathetic overdrive, as reflected by increased PWV and MSNA levels respectively. Additionally, exercise capacity demonstrates cardiovascular functional tolerance. These findings suggest that exercise testing provides determining clinical information regarding the overall cardiovascular status, proving its superior prognostic value as a hypertension screening tool, that alarms the physician to warn the patient to take action.

Abstract
Abstract
Background
It is unclear whether the Mediterranean diet (MedDiet) has a favorable effect on blood pressure (BP) levels because among randomized controlled trials (RCTs) investigating the MedDiet-mediated BP reduction there are significant methodological and clinical differences.
Purpose
The purpose of this study was to comprehensively assess the MedDiet BP-effect compared to the usual diet or another dietary intervention (e.g. low-fat diet) in adults with and without hypertension, accounting for different confounders.
Methods
We systematically searched Medline and the Cochrane Collaboration Library databases and identified 35 RCTs (13,943 participants). Random-effects model was used to calculate the mean attained systolic BP (SBP) and diastolic BP (DBP) differences during follow-up. Subgroup and meta-regression analyses were also conducted.
Results
Compared to the usual diet and all other active intervention diets the MedDiet reduced SBP and DBP (difference in means: −1.5 mm Hg; 95% CI: −2.8, −0.1; P=0.035, and −0.9 mm Hg; 95% CI: −1.5, −0.3; P=0.002, respectively). Compared only to the usual diet the MedDiet reduced SBP and DBP, while compared to all other active intervention diets or only to the low-fat diet the MedDiet did not reduce SBP and DBP. The MedDiet reduced DBP levels to a higher extent in trials with a mean baseline SBP ≥130 mm Hg, while both SBP and DBP were reduced more in trials with a mean follow-up period ≥16 weeks. The quality of evidence was rated as moderate for both outcomes according to the grading of recommendations, assessment, development and evaluation (GRADE) approach.
Conclusions
The adoption of the MedDiet was accompanied by a relatively small, but yet significant BP reduction, while higher baseline SBP levels and longer follow-up duration enhanced the BP-lowering effect of the intervention

Abstract
Abstract
Background/Introduction
Measurement of unattended blood pressure (BP) may provide additional information over conventionally attended BP. Moreover, hypertension is related to sympathetic drive while there are scarce data on the diverse links of attended and unattended BP with muscle sympathetic nerve activity (MSNA) in hypertensive patients.
Purpose
The aim of this study was to appraise the relation of BP levels in the attended and unattended setting with MSNA in patients with essential hypertension.
Methods
We studied 117 patients with essential hypertension (age: 58±11 years, 60 males, office BP: 142/85±17/10 mmHg, 24-hour BP: 133/80±11/9 mmHg). In all participants sympathetic drive was assessed by MSNA estimations based on established methodology (microneurography). Both unattended BP (patient alone in the room, an oscillometric device programmed to perform 3 BP measurements, at 1-minute intervals, after 5 minutes) and attended BP were measured with the same device, on the same day of MSNA recording, in random order. Patients were divided into the combined attended and unattended hypertensive group when BP≥140/90 mmHg in both attended and unattended BP estimations and to the attended hypertensive group when only attended BP≥140/90 mmHg.
Results
Patients with combined attended and unattended hypertension (n=70) compared to those with attended hypertension (n=47) did not differ regarding 24-h ambulatory BP levels, glucose levels, renal function and left ventricular mass index (p=NS for all). Moreover, patients with combined attended and unattended hypertension compared to those with attended hypertension were characterized by greater levels of MSNA (43.7±9.9 vs 37.7±9.7 bursts per minute, p=0.032). In all participants, sympathetic nerve traffic as assessed by resting MSNA was related to attended systolic BP (r=0.270, p=0.003), attended diastolic BP (r=0.344, p=0.001), unattended systolic BP (r=0.263, p=0.004) and unattended diastolic BP (r=0.274, p=0.003).
Conclusions
The phenotype of combined attended and unattended hypertension compared to attended hypertension is accompanied by higher sympathetic nervous system activation. Moreover, the close association of MSNA with attended and unattended BP levels in essential hypertension, further supports the key role of sympathetic drive in modulating BP.

Abstract
Abstract
Objective
Recent guideline recommendations have revisited the optimal target blood pressure (BP) for hypertensive patients. The Time in BP Range (TBPR) is an alternative metric for evaluation of long-term achieved BP. We investigated the association of TBPR for different levels of BP control with cardiovascular outcome among treated hypertensives.
Design and method
This is a retrospective analysis of 1202 treated hypertensive patients (age 59±11 years) without a history of cardiovascular disease followed for a mean period of 7±3 years. We calculated the TBPR [(No of Visits in BP range/ Total No of Visits) x 100%] for office systolic BP targets of 130–139mmHg, 120–129mmHg and <120mmHg and examined the associated cardiovascular risk. The outcome studied was the composite of stroke and coronary artery disease. Time spent in systolic BP≥140mmHg served as the reference.
Results
In the entire population, mean TBPR for systolic BP 130–139mmHg, 120–129mmH, and <120mmHg were 26%, 19% and 11% respectively. A TBPR of ≥50% for systolic BP 130–139mmHg, 120–129mmHg and <120mmHg was observed in 332 (28%), 226 (19%) and 107 (9%) patients respectively. The composite endpoint occurred in 54 patients (4.5%). Patients with a TBPR for 120–140mmHg of ≥50% presented with a HR: 0.6 (95% CI: 0.34–1.06) for cardiovascular events. The TBPR of ≥50% for systolic BP 130–139mmHg, 120–129mmHg and <120mmHg was associated with HR of 0.48 (95% CI: 0.23–1.01, p=0.05), 0.64 (95% CI: 0.29–1.39, p=0.26) and 0.72 (95% CI: 0.26–2.05) respectively. This pattern was sustained but further attenuated after controlling for standard risk factors. In comparison, a mean BP across visits of 130–139mmHg, 120–129mmHg and <120mmHg was associated with a HR of 0.54 (5% CI: 0.28–1.03), 0.61 (95% CI: 0.29–1.26) and 0.80 (95% CI: 0.24–2.65).
Conclusions
Among treated hypertensives, a time in BP of 130–140mmHg of more than 50% is associated with the greatest reduction in cardiovascular risk. The TBPR is a potentially useful measure of BP control for evaluation of risk reduction in hypertensive patients.

Abstract
Abstract
Background
Current hypertension guidelines necessitate an individualized cardiovascular risk assessment through a process that includes several parameters and remains challenging. Exercise capacity has been strongly associated with prognosis in cardiovascular disease and can be easily assessed by the exercise treadmill test (ETT).
Purpose
The aim of the present study was to investigate theprognostic role of exercise capacity for future cardiovascular events in a cohort of essential hypertensive subjects.
Methods
We followed up 1037 hypertensive adults (mean age 56 years, 53% males) with no previous history of cardiovascular disease, for a mean period of 6±3 years. During the baseline visit all subjects underwent a complete echocardiographic study, office blood pressure measurements, ECG, routine blood testing and an ETT with a Bruce protocol.During follow-up, all subjects were reviewed at least annually. Exercise capacity was expressedwithexercise duration the distribution of which was split by the median (9min). Accordingly, the subjects were classified into those with high (51%) and low exercise capacity (49%). The cardiovascular endpoint of interest was the composite of coronary artery disease and stroke.
Results
The incidence of cardiovascular eventsduring the follow-up period was 4.1% (35 cases of coronary artery disease and 10 cases of stroke).Cox regression analysis revealed that high exercise capacity was associated with a lower risk for future cardiovascular events (HR = 0.35 (95% CI 0.172–0.741, p=0.006). In multivariate models adjusting for standard clinical and laboratory cardiovascular risk factors this association was sustained.
Conclusion
Exercise duration shows a significant prognostic value for future CV events among hypertensivepatients. Exercise capacity assessment by means of TTE could enhance the identification of asymptomatic hypertensives at higher risk.

Combined lack of blood pressure and lipid control is a major risk factor for mortality in hypertensive patients: a single-center study. Eur Heart J 2020.

Abstract
Abstract
Background
Hypertension and dyslipidemia are well-known risk factors for cardiovascular disease (CVD). In such patients, lowering blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) and targeting to values below pre-specified cut-offs prevents CV events and improves prognosis. However, the impact of both BP and LDL-C control as compared to control of only one and/or none of these two risk factors is not well-studied.
Methods
Among 2,380 treated patients with hypertension and no overt CVD at baseline, we assessed the trajectory of BP control in 1,142 subjects with 4 or more follow up visits; BP control was defined as BP<140/90 mmHg in half or more visits. In the same subgroup, data on lipid control according to LDL-C goals were available in 1,032 patients in 2 or 3 visits. The HeartScore was used to estimate the risk of all-cause death at baseline.
Results
Across a median follow up of 108 months, 26 deaths (2.44%) were recorded. Despite appropriate anti-hypertensive treatment, 376 patients (32.92%) did not achieve conventional BP control in half or more of follow-up visits. Respectively, 59.83% of the study population did not meet the LDL-C goals in at least one assessment. Patients with suboptimal BP control had almost 3-fold increased risk for all-cause mortality (HR=2.85, 95% CI 1.31–6.21, P=0.008) as compared to subjects with effective control. This association was not attenuated after taking into account age, gender, body mass index, smoking, and diabetes mellitus (adjusted HR=2.54, 95% CI 1.13–5.72, P=0.025). Ineffective LDL-C control was not related to death (HR=1.31, 95% CI 0.688–2.48). However, patients who did not reach treatment goals for both BP and LDL showed substantially increased risk for all-cause mortality (HR=5.42, 95% CI 1.09–26.9, P=0.039). Importantly, suboptimal BP control in our cohort of hypertensive patients was associated with death independently of the HeartScore (adjusted HR=2.65, 95% CI 1.22–5.77, P=0.014) and conferred incremental reclassification value on top of the baseline risk (continuous NRI=0.467, P=0.016).
Conclusions
Suboptimal BP control was related to all-cause mortality in our cohort of hypertensive patients; importantly, this association was substantially stronger in concurrent presence of LDL-C values above treatment targets, thus, highlighting the need for combined achievement of BP and LDL-C control. Moreover, association of suboptimal BP controlwith death was independent of the HeartScore, suggesting that BP control should be considered in risk stratification of hypertensive patients

Abstract
Abstract
Background
Data on prevalence and associated prognosis of repolarization abnormalities among hypertensive patients are limited.
Purpose
We investigated the presence and extent of ST-segment and T-wave changes in a hypertensive population and their predictive ability for cardiovascular disease.
Methods
We studied 1851 white Caucasian hypertensive patients (age 58±12 years, 51%females) without a history of cardiovascular disease for a mean period of 5.3±3.4 years. At the baseline examination, all patients underwent standard 12-lead electrocardiography. T-wave inversion (TWI) was defined as T-wave deflection ≥−0.1 mV in ≥2 contiguous leads,unless associated with bundle branch block. Anterior, lateral or inferior TWI was defined as TWIin leads V2-V4 or V5,V6, I, AVL or II, aVF respectively. Thedepth in millimeters of TWI in each lead was recorded and the maximum depth per location was calculated. ST depression was defined as ≥1mm in depth in two or more contiguous leads.During follow-up, patients underwent clinic visits at least yearly for management of hypertension and risk factors. The outcome studied was theincidence of cardiovascular morbidity set as the composite of non-fatal coronary artery disease and stroke.
Results
In the entire population, prevalence of TWI was 3.8%, of which 39% presented withanterior TWI, 73% withlateral TWI and 11% with inferior TWI. ST depression was observed in 3.6% of patients (anterior in 0.8%, inferior in 0.9% and lateral in 2.6%). Incidence of the composite endpoint during follow-up was 4%. Cox regression analysis revealed that presence of TWI was associated with a significantly greater risk for cardiovascular events (HR: 2.6, 95% CI: 1.1–5.9, p=0.025). The association was stronger for lateral TWI (HR: 3.3, 95%: CI: 1.34–8.30, p=0.01) compared to other locations. In multivariate models controlling for standard confounders these associations were overall sustained. Depth of TWI and presence of ST depression were not associated with cardiovascular risk.
Conclusions
Among hypertensive patients without cardiovascular disease, TWI is infrequent but significantly associated with future cardiovascular events.Lateral TWI carries the worse prognosis

Abstract
Abstract
Background/Introduction
For estimation of overall cardiovascular risk the European Society of Hypertension (ESH) proposes stratification according to blood pressure (BP), prevalence of risk factors, asymptomatic target organ damage, diabetes, kidney and symptomatic cardiovascular disease, while the European Society of Cardiology (ESC) HeartScore constitutes another potent predictive tool of adverse outcome.
Purpose
The aim of the present study was to compare the predictive role of ESH stratification and ESC HeartScore for the incidence of the composite end-point of coronary artery disease (CAD) and stroke in a cohort of essential hypertensive patients.
Methods
We followed up 2150 essential hypertensives (mean age 55.7 years, 1085 males, office BP=145/91 mmHg) for a mean period of 8 years. All subjects had at least one annual visit. Patients were divided based on the ESH risk categories as well as according to the ESC HeartScore. CAD was defined as the history of myocardial infarction or significant coronary artery stenosis revealed by angiography or coronary revascularization procedure. Stroke was defined as rapid onset of a new neurological deficit persisting at least 24 hours unless death supervened confirmed by imaging findings.
Results
The incidence of CAD, stroke and their composite over the follow-up period were 2.8% (n=60), 1.11% (n=24) and 3.9% (n=84), respectively. By using the ESH stratification, regarding the total population 15.3% (n=329) was of low and moderate risk, 54.4% (n=1170) was of moderate to high and high risk and 30.3% (n=651) was high to very high and very high risk. According to the ESC HeartScore 89.2% (n=1918) was of low to moderate risk, 10% (n=215) of high risk and 0.8% (n=17) of very high risk. Cox-regression analyses revealed that high to very high and very high ESH risk category was related to increased risk for the composite end-point of CAD and stroke (hazard ratio=4.5, p<0.0001), while focusing on the ESC Heart Score the composite end-point was predicted by the high risk category (hazard ratio=3.43, p<0.0001). Using the Akaike's information criterion the ESH risk model had better fit than the ESC HeartScore due to the lowest Akaike's values (1442.66 vs 1498.31, respectively).
Conclusions
In essential hypertensive patients categorization of patients by means of the ESH stratification and the ESC HeartScore are both predictive of future cardiovascular events. Based on our results, the ESH risk stratification constitutes a better prediction model for CAD and stroke than the ESC HeartScore in essential hypertension and its estimation is essential in order to improve overall risk assessment in this setting.

Abstract
Abstract
Background/Introduction
Renal dysfunction is related with adverse prognosis in hypertension, however there are scarce data on the predictive cardiovascular and renal impact of kidney function variability in this setting.
Purpose
The aim of the present study was to assess the predictive role of visit-to-visit renal function changes on the incidence of coronary artery disease (CAD), stroke and end-stage renal disease in a cohort of essential hypertensive patients.
Methods
We followed up 2380 essential hypertensives (mean age 58.9 years, 1240 males, office blood pressure (BP)=144/91 mmHg) free of cardiovascular disease for a mean period of 8 years. All subjects had at least one annual visit and blood sampling was performed in all visits for estimation of glomerular filtration rate (GFR). We calculated standard deviation (SD) of mean GFR from visits from 6 months onward in patients with ≥5 visits during follow-up. CAD was defined as the history of myocardial infarction or significant coronary artery stenosis revealed by angiography or coronary revascularization procedure, while stroke was defined as rapid onset of a new neurological deficit persisting at least 24 hours unless death supervened confirmed by imaging findings. End-stage renal disease was defined as GFR<15 mL/min/1.73 m2 or the need for long-term dialysis or transplantation.
Results
The incidence of CAD, stroke and end-stage renal disease over the follow-up period were 2.8% (n=68), 1.09% (n=26) and 0.6% (n=14). Hypertensives who developed CAD compared to those without CAD at follow-up (n=2312) had at baseline higher left ventricular mass index (115.7±24.6 vs 103.7±27.3 g/m2, p<0.0001), whereas there was no difference with respect to baseline GFR (78±19.6 vs 79.3±18.6 mL/min/1.73 m2 (p=0.573). In multivariate Cox regression models visit-to-visit glomerular filtration rate predicted end-stage renal disease (hazard ratio=1.758, p=0.01) but not CAD and stroke (p=NS for both). Baseline left ventricular mass index independently predicted CAD (hazard ratio=1.042, p=0.015) and stroke (hazard ratio=1.035, p=0.002).
Conclusions
In essential hypertensive patients GFR variability predicts future development of end-stage renal disease but exhibits no independent prognostic value for CAD and stroke. These results suggest that fluctuations of renal function are related with damage at the kidneys and not at the cardiac and cerebrovascular level.

Abstract
Abstract
Background/Introduction
Isolated systolic hypertension (ISH) and combined systolic-diastolic hypertension (CH) are related with increased cardiovascular risk.
Purpose
The aim of the present study was to compare the predictive role of ISH and CH for the incidence of atrial fibrillation (AF) in a cohort of essential hypertensive patients.
Methods
We followed up 1605 essential hypertensives with office systolic blood pressure (BP)≥140 mmHg [mean age 58.1 years, 842 males, office BP=153/92 mmHg] for a mean period of 8 years. All subjects had at least one annual visit and at baseline underwent echocardiographic study and blood sampling for estimation of metabolic profile. Patients with baseline ISH exhibited office systolic BP ≥140 mmHg and office diastolic BP <90 mmHg, while those with CH had office systolic BP ≥140 mmHg and office diastolic BP ≥90 mmHg. Moreover, new-onset AF was defined as hospitalization for AF or compatible electrocardiographic tracings.
Results
The incidence of new-onset AF over the follow-up period was 3.4% (n=55). Patients with ISH (n=510) compared to those with CH (n=1095) were older (65±10 vs 55±11 years, p<0.0001), had at baseline lower waist circumference (95.5±12 vs 98±12 cm, p<0.0001), office systolic BP (149±10 vs 155±13 mmHg, p<0.0001), office diastolic BP (80±5 vs 98±7 mmHg, p<0.0001), while did not differ regarding left ventricular mass index and lipid levels (p=NS for all). Univariate Cox regression analysis revealed that baseline ISH (hazard ratio=4.612, p=0.013) and CH (hazard ratio=1.794, p=0.036) predicted new-onset AF. However, in multivariate Cox regression model, age (hazard ratio=1.078, p<0.001), left ventricular mass index (hazard ratio 1.012, p=0.014), left atrium diameter (hazard ratio=1.102, p<0.001) and ISH (hazard ratio=1.551, p=0.035) but not CH turned out to be independent predictors of new-onset AF episodes.
Conclusions
In essential hypertensive patients, ISH but not CH exhibits independent prognostic value for AF. These findings support that ISH constitutes a hypertensive phenotype of particularly increased arrhythmia risk needing careful evaluation and treatment.

Abstract
Background/Introduction
Isolated systolic hypertension (ISH) and combined systolic-diastolic hypertension (CH) are related with increased cardiovascular risk, while new-onset diabetes mellitus (NOD) is linked with atherosclerosis progression.
Purpose
The aim of the present study was to compare the predictive role of ISH and CH for the incidence of NOD in a cohort of essential hypertensive patients.

We followed up 1435 non-diabetic essential hypertensives with office systolic blood pressure (BP)≥140 mmHg [mean age 57 years, 730 males, office BP=153/92 mmHg] for a mean period of 8 years. All subjects had at least one annual visit and at baseline underwent echocardiographic study and blood sampling for estimation of metabolic profile. Patients with baseline ISH exhibited office systolic BP ≥140 mmHg and office diastolic BP <90 mmHg, while those with CH had office systolic BP ≥140 mmHg and office diastolic BP ≥90 mmHg. Moreover, NOD was defined if at one or more of the follow-up visits a previously non-diabetic patient reported being on insulin or an oral hypoglycemic drug or if casual plasma glucose concentration ≥200 mg/dl or fasting glucose concentration ≥126 mg/dl or 2-h post load glucose ≥200 mg/dl during an oral glucose tolerance test.
Results
The incidence of NOD over the follow-up period was 4.2% (n=60). Patients with ISH (n=460) compared to those with CH (n=975) were older (65±11 vs 54±10 years, p<0.0001), had at baseline lower waist circumference (94.5±11 vs 99±13 cm, p<0.0001), office systolic BP (149±12 vs 155±13 mmHg, p<0.0001), office diastolic BP (80±8 vs 98±6 mmHg, p<0.0001), while did not differ regarding left ventricular mass index, glucose and lipid levels (p=NS for all). Univariate Cox regression analysis revealed that baseline ISH (hazard ratio=2.143, p=0.016) and CH (hazard ratio=1.272, p=0.029) predicted NOD. However, in multivariate Cox regression model, age (hazard ratio=1.039, p<0.001), baseline glucose levels (hazard ratio 1.011, p=0.016), waist circumference (hazard ratio=1.067, p<0.001) and ISH (hazard ratio=1.651, p=0.029) but not CH turned out to be independent predictors of NOD.
Conclusions
In essential hypertensive patients, ISH but not CH exhibits independent prognostic value for NOD. These findings support that ISH constitutes a hypertensive phenotype of increased metabolic risk needing careful evaluation and treatment.

Abstract
Abstract
Background/Introduction
Although arterial stiffening is related to atherosclerosis progression, its prognostic role in hypertension is not fully elucidated, while augmented left ventricular mass index (LVMI) is linked to adverse outcome.
Purpose
The aim of the present study was to compare the predictive role of changes in arterial stiffness and LVMI for the incidence of coronary artery disease (CAD) in a cohort of essential hypertensive patients.
Methods
We followed up 1082 essential hypertensives (mean age 55.9 years, 562 males, office blood pressure (BP)=145/91 mmHg) free of cardiovascular disease for a mean period of 8 years. All subjects had at least one annual visit and at baseline and last visit underwent complete echocardiographic study for estimation of LVMI and measurements of arterial stiffness on the basis of carotid to femoral pulse wave velocity (PWV), by means of a computerized method. The distribution of PWV was split by the median (8.2 m/sec) and accordingly subjects were classified into those with high (n=546) and low values (n=536). Moreover, LV hypertrophy (LVH) was defined as LVMI ≥125 g/m2 in males and LVMI ≥110 g/m2 in females, while CAD was defined as the history of myocardial infarction or significant coronary artery stenosis revealed by angiography or coronary revascularization procedure.
Results
The incidence of CAD over the follow-up period was 3.5%. Hypertensives who developed CAD (n=38) compared to those without CAD at follow-up (n=1044) had at baseline higher waist circumference (101.7±10.1 vs 96.2±11.6 cm, p=0.004), LVMI (123.9±22.1 vs 105.8±21.3 g/m2, p=0.026), prevalence of LVH (46% vs 25%, p=0.018) and prevalence of high PWV levels (67% vs 40%, p=0.021). No difference was observed between hypertensives with CAD and those without CAD with respect to baseline office BP, serum creatinine and lipid levels (p=NS for all). By univariate Cox regression analysis, it was revealed that changes in PWV levels between baseline and last visit predicted CAD (hazard ratio=1.243, p=0.014). However, in multivariate Cox regression model baseline glomerular filtration rate (hazard ratio=1.029, p=0.015) and changes in LVMI (hazard ratio=1.036, p<0.0001) but not alterations of PWV turned out to be independent predictors of CAD.
Conclusions
In essential hypertensive patients changes in LVMI predict future development of CAD, whereas PWV alterations exhibit no independent prognostic value. These findings support that LVMI constitutes a superior prognosticator of events than PWV and its estimation is essential in order to improve overall risk stratification in hypertension.

Abstract
Abstract
Background/Introduction
Measurement of unattended blood pressure (BP) may provide additional information over conventionally attended BP. Moreover, hypertension is related to sympathetic drive while there are scarce data on the diverse links of attended and unattended BP with muscle sympathetic nerve activity (MSNA) in hypertensive patients.
Purpose
The aim of this study was to assess the relation of BP levels in the attended and unattended setting with MSNA in patients with essential hypertension.
Methods
We studied 38 patients with essential hypertension (age: 59±11 years, 20 males, office BP: 142/86±19/11 mmHg, 24-hour BP: 137/80±14/12 mmHg). In all participants sympathetic drive was assessed by MSNA estimations based on established methodology (microneurography). Both unattended BP (patient alone in the room, an oscillometric device programmed to perform 3 BP measurements, at 1-minute intervals, after 5 minutes) and attended BP were measured with the same device, on the same day of MSNA recording, in random order. Patients were divided into the combined attended and unattended hypertensive group when BP≥140/90 mmHg in both attended and unattended BP estimations and to the attended hypertensive group when only attended BP≥140/90 mmHg.
Results
Patients with combined attended and unattended hypertension (n=18) compared to those with attended hypertension (n=20) were older (61±11 vs 57±11 years, p=0.03), whereas did not differ regarding 24-h ambulatory BP levels, glucose levels, renal function and left ventricular mass index (p=NS for all). Moreover, patients with combined attended and unattended hypertension compared to those with attended hypertension were characterized by greater levels of MSNA (41.2±11.6 vs 32.2±10.1 bursts per minute, p=0.031). In all participants, sympathetic nerve traffic as assessed by resting MSNA was related to attended systolic BP (r=0.459, p=0.004), attended diastolic BP (r=0.503, p=0.001), unattended systolic BP (r=0.433, p=0.007) and unattended diastolic BP (r=0.423, p=0.008).
Conclusions
The phenotype of combined attended and unattended hypertension compared to attended hypertension is accompanied by higher sympathetic nervous system activation. Moreover, the close association of MSNA with attended and unattended BP levels in essential hypertension, further supports the key role of sympathetic drive in modulating BP.

Abstract
Abstract
Background/Introduction
Although arterial stiffening is related to atherosclerosis progression, the prognostic role of its alterations in cerebrovascular events in hypertension is not fully elucidated.
Purpose
The aim of the present study was to assess the predictive role of changes inarterial stiffness for the incidence of stroke in a cohort of essential hypertensive patients.
Methods
We followed up 1082 essential hypertensives (mean age 55.9 years, 562 males, office blood pressure (BP)=145/91 mmHg) for a mean period of 8 years. All subjects had at least one annual visit and underwent blood sampling for assessment of metabolic profile, whilearterial stiffness was evaluated on the basis of carotid to femoral pulse wave velocity (PWV), by means of a computerized method at the initial and last visit. The distribution of baseline PWV was split by the median (8.2 m/sec) and accordingly subjects were classified into those with high (n=546) and low values (n=536). Stroke was defined as rapid onset of a new neurological deficit persisting at least 24 hours unless death supervened confirmed by computed tomography and magnetic resonance angiography and/or cerebrovascular angiography findings.
Results
The incidence of stroke over the follow-up period was 2.2%. Hypertensives who had stroke (n=24) compared to those without stroke at follow-up (n=1058) were older at baseline (65±9 vs 56±12 years, p=0.032), had higher office BP levels (155±13 vs 145±15mmHg, p=0.014) and prevalence of high PWV levels (67% vs 40%, p=0.021). No difference was observed between hypertensives with stroke and those without stroke with respect to baseline renal function and lipid levels (p=NS for all). By univariate Cox regression analysis it was revealed that changes in PWV levels between baseline and last visit predicted stroke (hazard ratio=1.352, p=0.004). Moreover, in multivariate Cox regression model, baseline age (hazard ratio=1.087, p=0.03), changes in PWV (hazard ratio=1.115, p=0.024) but not changes in office BP levels turned out to be independent predictors of stroke.
Conclusions
In essential hypertensive patients, changes in PWV predict future development of stroke, independently of established confounders, including BP. These findings support that PWV constitutes a potent prognosticator of cerebrovascular events and its estimation is essential in order to improve risk stratification in hypertension.
