Abstract
Renal Denervation (RDN) is an interventional, endovascular procedure used for the management of hypertension. The procedure itself aims to ablate the renal sympathetic nerves and to interrupt the renal sympathetic nervous system overactivation, thus decreasing blood pressure (BP) levels and total sympathetic drive in the body. Recent favorable evidence for RDN resulted in the procedure being included in the recent European Guidelines for the management of Hypertension, while RDN is considered the third pillar, along with pharmacotherapy, for managing hypertension. Sympathetic overactivation, however, is associated with numerous other pathologies, including diabetes, metabolic syndrome and glycemic control, which are linked to adverse cardiovascular health and outcomes. Therefore, RDN, via ameliorating sympathetic response, could be also proven beneficial for maintaining an euglycemic status in patients with cardiovascular disease, alongside its BP-lowering effects. Several studies have aimed, over the years, to provide evidence regarding the pathophysiological effects of RDN in glucose homeostasis as well as investigate the potential clinical benefits of the procedure in glucose and insulin homeostasis. The purpose of this review is, thus, to analyze the pathophysiological links between the autonomous nervous system and glycemic control, as well as provide an overview of the available preclinical and clinical data regarding the effect of RDN in glycemic control.

Abstract
Heart failure is increasingly prevalent and is estimated to increase its burden in the following years. A well-reported comorbidity of heart failure is renal dysfunction, where predominantly changes in the patient's volume status, tubular necrosis or other mechanical and neurohormonal mechanisms seem to drive this impairment. Currently, there are established biomarkers evaluating the patient's clinical status solely regarding the cardiovascular or renal system. However, as the coexistence of heart and renal failure is common and related to increased mortality and hospitalization for heart failure, it is of major importance to establish novel diagnostic techniques, which could identify patients with or at risk for cardiorenal syndrome and assist in selecting the appropriate management for these patients. Such techniques include biomarkers and imaging. In regards to biomarkers, several peptides and miRNAs indicative of renal or tubular dysfunction seem to properly identify patients with cardiorenal syndrome early on in the course of the disease, while changes in their serum levels can also be helpful in identifying response to diuretic treatment. Current and novel imaging techniques can also identify heart failure patients with early renal insufficiency and assess the volume status and the effect of treatment of each patient. Furthermore, by assessing the renal morphology, these techniques could also help identify those at risk of kidney impairment. This review aims to present all relevant clinical and trial data available in order to provide an up-to-date summary of the modalities available to properly assess cardiorenal syndrome.

Abstract
BACKGROUND & AIMS Non-pharmacological measures are recommended as the first-line treatment for individuals with high-normal blood pressure (BP) or mild hypertension. Studies directly comparing the BP effects of the Dietary Approaches to Stop Hypertension (DASH) vs. the Mediterranean diet (MedDiet) on a salt restriction background are currently lacking. Thus, our purpose was to assess the BP effects of a 3-month intensive dietary intervention implementing salt restriction either alone or in the context of the DASH, and the MedDiet compared to no/minimal intervention in adults with high normal BP or grade 1 hypertension. METHODS We randomly assigned never drug-treated individuals to a control group (CG, n = 60), a salt restriction group (SRG, n = 60), a DASH diet with salt restriction group (DDG, n = 60), or a MedDiet with salt restriction group (MDG, n = 60). The primary outcome was the attained office systolic BP difference among the randomized arms during follow-up. RESULTS A total of 240 patients were enrolled, while 204 (85%) completed the study. According to the intention-to-treat analysis, compared to the CG, office and 24 h ambulatory systolic and diastolic BP were reduced in all intervention groups. A greater reduction in the mean office systolic BP was observed in the MDG compared to all other study groups (MDG vs. CG: mean difference = -15.1 mmHg; MDG vs. SRG: mean difference = -7.5 mmHg, and MDG vs. DDG: mean difference = -3.2 mmHg, all P-values <0.001). The DDG and the MDG did not differ concerning the office diastolic BP and the 24 h ambulatory systolic and diastolic BP; however, both diets were more efficient in BP-lowering compared to the SRG. CONCLUSIONS On a background of salt restriction, the MedDiet was superior in office systolic BP-lowering, but the DASH and MedDiet reduced BP to an extent higher than salt restriction alone.

Abstract
Current evidence on the prognosis of patients with a hypertensive crisis and predisposing factors is limited. We registered the clinical phenotype of patients with HC admitted to the emergency department, while those with a hypertensive emergency (HE) were hospitalized. One-year outcomes, i.e., composite of death or cardiovascular hospitalizations, were determined in patients with HE after hospital discharge. Out of 38,589 patients assessed in the emergency department, 256 hypertensive urgencies and 97 HE was registered. After stratification of the HE by sex, 48 men and 46 women completed the one-year follow-up. Men had more events than women (27 vs. 13, Ηazard Ratio 2.2, 95% Confidence Interval 1.03-4.7, p = 0.042) after adjustment for age, cardiovascular or chronic kidney disease, and diabetes mellitus. Our study raises the hypothesis that the male sex is an independent risk factor for cardiovascular outcomes in HE patients. CV Cardiovascular, BP blood pressure. The diagram presents the groups of comparison, men versus women in hypertensive emergencies that completed the 1-year follow-up for outcomes, in terms of hospitalizations or deaths.

Abstract
PURPOSE We investigated whether blood pressure (BP) control measures, visit-to-visit BP variability, and time in therapeutic range (TTR) are associated with future cardiovascular outcomes in hypertensive patients. MATERIALS AND METHODS Among 1,408 hypertensive patients without cardiovascular disease, we prospectively evaluated the incident major cardiovascular events over 6 years. In newly diagnosed patients, antihypertensive drug treatment was initiated. We estimated two markers of on-treatment BP control, (1) visit-to-visit BPV as the coefficient of variation of office systolic BP (BP-CV), and (2) TTR calculated as the percentage of office systolic BP measurements within 120-140mmHg across visits. RESULTS The hypertensive cohort (672 males, mean age 60 years, 31% newly diagnosed) had a mean systolic/diastolic BP of 142/87 mmHg. The mean number of visits was 4.9 ± 2.6, while the mean attained systolic/diastolic BP during follow-up was 137/79 mmHg using 2.7 ± 1.1 antihypertensive drugs. The BP-CV and TTR were 9.1 ± 4.1% and 45 ± 29%, respectively, and the incidence of the composite outcome was 8.3% (n = 117). After adjustment for relevant confounders and standardization to z-scores, BP-CV and TTR were associated with a 43% (95% CI, 27-62%) increase and a 33% (95% CI, 15-47%) reduction in the outcome. However, the joint evaluation of TTR and BP-CV in a common multivariable model indicated that a standardized change of TTR was associated with the outcome to a greater extent than BP-CV (mean hazard ratios of 30% vs. 24%, respectively). When combined with the higher BP standardized-CV quartile, the lower TTR quartile predicted the outcome by 2.3 times (95% CI, 1.1-5.4) compared to the inverse TTR and BP-CV quartile pattern. CONCLUSION High BP-CV or low TTR was associated with future cardiovascular events in a cohort of treated hypertensive patients. As a determinant, the extent of TTR value appears greater than BP-CV when these measures are considered in the same multivariable model.

Abstract
Out-of-office blood pressure (BP) measurement is considered an integral component of the diagnostic algorithm and management of hypertension. In the era of digitalization, a great deal of wearable BP measuring devices has been developed. These digital blood pressure monitors allow frequent BP measurements with minimal annoyance to the patient while they do promise radical changes regarding the diagnostic accuracy, as the importance of making an accurate diagnosis of hypertension has become evident. By increasing the number of BP measurements in different conditions, these monitors allow accurate identification of different clinical phenotypes, such as masked hypertension and pathological BP variability, that seem to have a negative impact on cardiovascular prognosis. Frequent measurements of BP and the incorporation of new features in BP variability, both enable well-rounded interpretation of BP data in the context of real-life settings. This article is a review of all different technologies and wearable BP monitoring devices.

Abstract
The SPYRAL HTN-OFF MED Pivotal trial ( https://clinicaltrials.gov/ct2/show/NCT02439749 ) demonstrated significant reductions in blood pressure (BP) after renal denervation (RDN) compared to sham control in the absence of anti-hypertensive medications. Prior to the 3-month primary endpoint, medications were immediately reinstated for patients who met escape criteria defined as office systolic BP (SBP) ≥ 180 mmHg or other safety concerns. Our objective was to compare the rate of hypertensive urgencies in RDN vs. sham control patients. Patients were enrolled with office SBP ≥ 150 and < 180 mmHg, office diastolic BP (DBP) ≥ 90 mmHg and mean 24 h SBP ≥ 140 and < 170 mmHg. Patients had been required to discontinue any anti-hypertensive medications and were randomized 1:1 to RDN or sham control. In this post-hoc analysis, cumulative incidence curves with Kaplan-Meier estimates of rate of patients meeting escape criteria were generated for RDN and sham control patients. There were 16 RDN (9.6%) and 28 sham control patients (17.0%) who met escape criteria between baseline and 3 months. There was a significantly higher rate of sham control patients meeting escape criteria compared to RDN for all escape patients (p = 0.032), as well as for patients with a hypertensive urgency with office SBP ≥ 180 mmHg (p = 0.046). Rate of escape was similar between RDN and sham control for patients without a measured BP exceeding 180 mmHg (p = 0.32). In the SPYRAL HTN-OFF MED Pivotal trial, RDN patients were less likely to experience hypertensive urgencies that required immediate use of anti-hypertensive medications compared to sham control.

Abstract
Background/Introduction
Sympathetic nervous system activation plays a crucial role in the pathophysiology and variability of hypertension. It has been hypothesized that measurement of unattended blood pressure (BP) may provide additional information to conventionally attended BP measurement, as it can lead to the limitation of the white coat effect.
Purpose
The aim of this study was to demonstrate the relationship of sympathetic nervous system activation and BP measurement variations with and without medical supervision.

We studied 103 untreated hypertensive patients, who underwent muscle sympathetic nerve activity (MSNA) estimation by microneurography. Both unattended (patient alone in the room, an oscillometric device programmed to perform 3 BP measurements at 1-minute intervals, after 5 minutes of rest) and attended BP measurements were conducted in all participants, with the same device, on the same day of MSNA recording in random order. Patients were divided into two groups based on the difference between attended and unattended BP. In group A, patients had unattended BP greater than attended BP (n=31) and in group B, patients had unattended BP lower than attended BP (n=72). The two groups were compared regarding the median value of MSNA recordings in our population (median MSNA = 63 bursts per 100 heartbeats).
Results
The two groups did not differ as regards both attended SBP levels (group A: 142.3±15.4 mmHg, group B: 145.6±13.7 mmHg, p=0.29) and attended DBP levels (group A: 89.2±9.8 mmHg, group B: 91.2±11.5 mmHg, p=0.25). A difference was observed concerning unattended SBP levels (group A: 152±16.3 mmHg, group B: 142.5±13.8 mmHg, p=0.03) and unattended DBP levels (group A: 94.4±10.3 mmHg, group B: 85.2±11.8 mmHg, p<0.01). Higher levels of MSNA were recorded in patients in group A when compared to group B, although this difference was not statistically significant (66.8±15.6 vs. 61.6±14.8 bursts per 100 heartbeats, p=0.11). Higher percentage of patients in group A had MSNA levels greater than the median value of MSNA compared to group B (68% vs 46% respectively).
Conclusions
In the present study, we found that the majority of patients who exhibit higher BP during the unattended measurement also record high MSNA values, suggesting a more stimulated sympathetic nervous system. On the contrary, most of the patients who can calm down during the unattended measurement exhibit lower levels of MSNA. More patients are needed to fully determine the clinical significance of this observation.

Abstract
Abstract
Background/Purpose
A hypertensive response during exercise has been associated with adverse cardiovascular outcomes in general population and hypertensive patients. On the other hand, microcirculation is the major site of control of vascular resistance and thus has a key role in the etiopathogenesis of hypertension. The aim of our study was to investigate the presence of a possible correlation between blood pressure and heart rate response during exercise with a microcirculation index (capillary rarefaction) in a cohort of hypertensive patients.
Methods
We studied 105 untreated patients with stage I-II essential hypertension (70% men, mean age: 59.5 years, mean office blood pressure: 150/92mmHg). Patients with diabetes mellitus, secondary hypertension, atherosclerotic cardiovascular disease, heart failure, significant chronic renal or pulmonary disease and any other systemic illness or orthopedic problems that would not allow maximal effort on a treadmill were excluded. All participants underwent maximal exercise testing, using the Bruce protocol, as well as nail-fold videocapillaroscopy assessment by using VideoCap 3.0 videomicroscope.
Results
A significant negative correlation between diastolic BP at minute-1 of the recovery phase and capillary density expressed in capillaries/mm was revealed (Pearson's r=−0.365, p=0.043). A significant negative correlation was also observed between capillary density and peak heart rate (Pearson's r=−0.364, p=0.024) as well as between heart rate increase from stage 1 to 2 and capillary density (Pearson's r=−0.746, p=0.013).
Conclusions
Our study shows that in a small cohort of hypertensive patients, capillary rarefaction was associated with a steeper increase in heart rate during exercise, as well as with a higher peak heart rate and higher diastolic blood pressure values during the recovery phase. These findings suggest that new indices such as capillary rarefaction may provide insights into possible autonomic dysfunction and could also be taken into account in the assessment of hypertensive patients.

Abstract
Abstract
Background/Introduction
Blood pressure (BP) lowering is accompanied by a reduction on cardiovascular (CV) outcomes and death in hypertensive patients. There is no data on the effect of lowering BP in patients stratified according to their baseline CV risk as indicated by SCORE 2.
Purpose
The aim of this meta-analysis was to demonstrate the impact of BP-lowering treatment on the occurrence of CV events in these previously reported patients.
Methods
A systematic review in electronic databases (Pubmed and CENTRAL, years: 1966 to 9/2021) was conducted to identify randomized trials that study the effect of BP-lowering treatment against placebo or less aggressive BP reduction on 6 fatal or non-fatal CV outcomes and all-cause death. Selected studies reported outcomes in patients without a history of previous CV disease. In each study, baseline cardiovascular risk was estimated using SCORE-2. Risk ratios (RR) were calculated together with their 95% confidence interval (CI) under the random-effects model.
Results
The analysis was composed of 54 studies, of which 12 trials included patients with low-to-moderate CV risk, (n=21,192 patients), 13 trials with high CV risk patients (n=66,886) and 29 trials with very high CV risk patients (n=79,061). For a standard SBP/DBP reduction of 10/5 mmHg, the relative risk of the combined outcome of major CV events (i.e., myocardial infarction, stroke, and heart failure) was decreased by 27% (95% CI, 22–35%) in the category of very high-risk patients. This reduction was significantly greater (p=0.02) compared to high-risk trials (0.90 [95% CI, 0.77–1.04]). CV death showed a significant reduction in the high-risk group of patients compared to the low-moderate risk group (p=0.005), as well as in the very high-risk group compared to the low-moderate risk group (p=0.001). The same pattern was observed for all-cause death in the very high-risk group compared to the high-risk group (p=0.045).
Conclusions
With the present meta-analysis, we observed that the greatest benefit from BP lowering in primary prevention in the occurrence of CV events and mortality is observed in patients at higher baseline cardiovascular risk, as calculated by the SCORE-2.

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
Although the clinical questions of the recent glucose-lowering trials are principally oriented towards preventing macrovascular events, an updated review regarding renal outcome prevention is lacking. We assessed the impact of different antihyperglycemic classes on kidney damage progression. A systematic review and meta-analysis was performed by searching PubMed, Cochrane Collaboration Library, Medline, and previous overviews through June 2021 (any language) for earlier and contemporary glucose-lowering trials, including patients with, but not limited to, type 2 diabetes mellitus vs. placebo or less intense treatment. Incidences of kidney function worsening and macroalbuminuria development was extracted, and risk ratios and 95% confidence intervals (CI) under the random-effects model were calculated. The association between outcome reductions and glycohemoglobin (HBA1c) reductions was investigated through the meta-regression analyses. Among 27 eligible trials (n = 198,532 patients) an averaged HBA1c reduction of 0.6 ± 0.3% was followed by a reduction of 17% (95% CI, 8-25%) in worsening of kidney function, and of 25% (95% CI, 19-32%) in macroalbuminuria. Analog of human glucagon-like peptide 1 (GLP1)-agonists, and sodium-glucose cotransporter (SGLT2)-inhibitors, considered separately, compared with placebo, were associated with a significant reduction of both renal outcomes, at variance with dipeptidyl peptidase 4 (DPP4)-inhibitors, where no outcome change was observed. Logarithmic risk ratios of macroalbuminuria were related to HBA1c reductions, in contrast to the worsening of kidney function related to systolic blood pressure reduction. Worsening of kidney function and macroalbuminuria development were reduced following glucose-lowering. GLP1 agonists and SGLPT2 inhibitors were associated with protection against both outcomes, while DPP4 inhibitors do not provide renal protection.

Abstract
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.
Purpose
The aim of this study was to assess parameters related to the development of hypertension in a 3 year follow in subjects with high normal BP.
Methods
One hundred consecutive subjects with high normal office BP (54±8 years, 42 males, baseline office BP: 132/82 mmHg, 24-hour BP: 122/76 mmHg) at baseline underwent a negative for ischemia treadmill exercise test. Arterial stiffness was evaluated on the basis of carotid to femoral pulse wave velocity (PWV) values and sympathetic drive was assessed by muscle sympathetic nerve activity (MSNA) based on established methodology. SBP/MET-slope defined as: peak systolic BP–resting SBP)/(peak MET-1) was assessed. Follow up was scheduled every 6 months for 3 consecutive years, where BP was measured both in the office and with ambulatory blood pressure monitoring. End point was the development of hypertension diagnosed from office blood pressure measurements and confirmed from ambulatory blood pressure monitoring.
Results
Patients who developed hypertension (n=35) compared to those who remained normotensives (n=65) had at baseline higher prevalence of HRE (75% vs. 13%, p=0.026), higher levels of carotid to femoral PWV (8.35 vs. 7.5 m/sec, p=0.043) and MSNA (37 vs. 31 bursts per minute, p=0.04), while their metabolic profile did not differ at the follow up (p=NS for all). In those who developed hypertension, SBP/MET-slope was higher in all Bruce protocol stages till peak exercise (stage 1: 6.25 vs. 4.25, stage 2: 7.6 vs. 5.3, peak exercise: 7.22 vs. 5.1; p<0.05 for all). Additionally, those who remained normotensives compared to those who developed hypertension exhibited a higher exercise capacity (10 vs. 11.5 METs, p<0.05) and maximal heart rate at peak exercise (154 vs. 164, p=0.001).
Conclusion
In subjects with high normal BP, those who develop hypertension during follow-up are characterized by more frequent HRE accompanied with lower exercise capacity, arterial stiffening and sympathetic overactivation. These results suggest that exercise BP response, along with PWV and MSNA estimation could contribute to identify high normal BP subjects who are more prone to become hypertensives.

Abstract
Abstract
Background
Nonalcoholic fatty liver disease (NAFLD) represents the most frequent cause of chronic hepatic disease and independently determines hypertension and future cardiovascular events. Increased blood pressure variability (BPV) assessed by 24-hour blood pressure (BP) monitoring including mean arterial morning surge have been also associated with increased rates of cardiovascular events.
Purpose
To compare different BPV measures in hypertensive patients with and without NAFLD.
Methods
Consecutive newly diagnosed untreated hypertensive patients without history of cardiovascular disease underwent clinic and ambulatory BP measurements. NAFLD was diagnosed by liver ultrasound to separate patients into those with and without NAFLD. BPV was derived by assessment of standard deviation (SD) of systolic and diastolic BP (24-h, daytime and nighttime), average real variability (ARV) of systolic and diastolic BP, coefficient of variation (CV) of systolic BP (24-h, daytime), weighted SD (wSD) of systolic BP (24-h, daytime), maximum BP and mean arterial morning surge.
Results
Among 146 hypertensive patients (mean age 57±11 years, 64 men, 24-h mean systolic/diastolic BP 140±10/84±9 mmHg) those with NAFLD (n=76) compared to the non-NAFLD group (n=70) were younger (54.7±10.1 vs 58.6±11.2 years, respectively, p=0.03), male gender was more prevalent (42 vs 22 respectively, p=0.004), and body mass index was more increased (33.2±4.1 vs 27.0±3.5 kg/m2, p<0.001). Moreover, NAFLD patients compared to those without NAFLD were characterized by higher levels of mean arterial pressure morning surge (12.4±8.9 vs 8.7±8.5 mmHg, p=0.03), but the remaining BPV measures were not different between the two groups. NAFLD was a determinant of both diastolic BP ARV (B=0.34, p=0.007) and mean arterial morning surge (B=0.47, p=0.006) after adjustment.
Conclusions
Mean arterial pressure morning surge was significantly higher in hypertensive patients with NAFLD compared to their non-NAFLD counterparts, while whole day BPV measures were not increased in NAFLD except for ARV of diastolic BP. Our findings may partially explain the increased cardiovascular risk of comorbid NAFLD in hypertension.

Abstract
Abstract
Background
Few epidemiological data show a worst prognosis of hypertensive emergencies compared with hypertensive urgencies (HU). To the best of our knowledge, there is even fewer published evidence comparing prognosis of hypertensive patients (HP) with and without HU.
Purpose
The purpose of our prospective study was to record the prevalence and clinical characteristics of patients with HU assessed in the emergency department (ED) in a tertiary Hospital and to compare them with HP without urgencies for new events and hard-end points for a 12-month follow-up.
Methods
The study population consisted of 256 patients presenting at the ED with acute increase in blood pressure (BP) (systolic BP≥180mmHg and/or diastolic BP≥120mmHg) with absence of acute hypertension-mediated target organ damage in a period of one year. Each of these participants were matched one-to-one by age, gender and history of hypertension with HP with either controlled, grade 1 or grade 2 hypertension attending our Hypertension excellence center the same period. However, 78 of HU did not conclude the follow up and 5 could not be matched with HP for the above covariates and were therefore excluded. Both groups, 173 of HU and 173 of controls, concluded 12 months follow up for fatal and non fatal cardiovascular events, including acute coronary syndrome, stroke, newly diagnosed heart failure or deterioration of NYHA class, and composite end points such as stroke-myocardial infarction and overall cardiovascular disease outcome.
Results
The mean age of all patients was 64.9±12.5 years (64±12.2 for controls and 65.7±12.7 for HU), 48.8% were males (49.1% of controls and 48.6% of HU) and 26.6% had a history of smoking (22.5% of controls and 30.6% of HU). Overall, 15 (5.5%) patients had nonfatal clinical cardiovascular events and 4 (1.2%) had fatal cardiovascular events. Cox regression models were adjusted for age, gender, smoking, previous cardiovascular disease, diabetes mellitus and the population. The frequency of the composite stroke-myocardial infarction event was statistically significant higher in HU (5 vs 4, p<0.0001, Hazard Ratio for HU 181.7, 95% Confidence Intervals 19.7–1677.2) adjusted for the rest covariates. In addition, there was a higher trend for stroke in the group of HU (p=0.067) and in patients with a history of diabetes mellitus irrespective of group (p=0.055). Finally, the Cox regression analysis identified age (p=0.035) and history of cardiovascular disease (p=0.038) as independent predictors for death, and smoking (p=0.035) as independent predictor for overall cardiovascular events.
Conclusions
Our study emphasizes the higher trend for cardiovascular outcomes, especially stroke, in the group of HU compared with HP without urgencies, while it highlights the necessity for more intensive follow-up for the first group and the need for further research in this pathological entity.

Abstract
Abstract
Background
Nonalcoholic fatty liver disease (NAFLD) is associated with hypertension and predicts future cardiovascular events.
Purpose
To compare blood pressure (BP) morning surge assessed by ambulatory blood pressure monitoring (ABPM) in hypertensive patients with and without NAFLD.
Methods
Sixty-five consecutive patients with newly diagnosed essential hypertension (age 57±10 years, office BP 139/87±16/9 mmHg) were studied. In all patients a routine biochemical blood examination was undertaken while BP morning surge was automatically calculated by a Spacelabs 90207 device. NAFLD was confirmed by a liver ultrasound. Accordingly, patients were divided in those with and without NAFLD (control group).
Results
Patients with NAFLD (n=44) in comparison with controls (n=21) had similar 24h systolic (141.6±9.9 vs 143.2±10.4 mmHg) and diastolic BP (83.6±10.23 vs 84.7±9.53 mmHg) while office BP was also not different between groups (p=NS). However, those with NAFLD were younger (55±10 vs 61±9 years, respectively, p=0.046), had higher body mass index (32.5±4.5 vs 26.3±3.8 kg/m2, p<0.001), glomerular filtration rate (93.8±17 vs 82.6±9.2 ml/min/1.73m2, p=0.013), and higher levels of morning BP surge (14.29±8.5 vs 5.92±9.01mmHg, p=0.034), compared to the non-NAFLD group. Standard deviation of BP, average real variability, coefficient of variation and dipping status were not different between groups.
Conclusions
At the same levels of clinic and ambulatory BP, hypertensive patients with NAFLD compared to their non-NAFLD counterparts demonstrated increased morning surge BP levels. Our finding suggests that NAFLD may demonstrate a detrimental effect to early-morning at variance to the whole-day hemodynamics.

Abstract
Abstract
Background/Introduction
It is a well-known fact that the sympathetic nervous system is involved with the pathophysiology of hypertension. Smoking, which is one of the most significant risk factors for cardiovascular morbidity and mortality, also contributes to the development of hypertension mainly through the stimulation of the sympathetic nervous system. Moreover, measurement of unattended blood pressure (BP) may provide additional information compared to conventionally attended BP.
Purpose
The aim of this study was to demonstrate the impact of smoking on sympathetic nervous system stimulation, and on BP measurement variations with and without medical supervision.
Methods
We studied patients with essential hypertension, who were separated into two groups, depending on their smoking habits (Group I: non-smokers, Group II: smokers). In all participants, sympathetic drive was assessed by MSNA estimations based on established methodology (microneurography). Both unattended (patient alone in the room, an oscillometric device programmed to perform 3 BP measurements, at 1-minute intervals, after 5 minutes of rest) and attended BP measurements were conducted with the same device, on the same day of MSNA recording, in random order. Then, we compared the two BP measurement values of each patient to assess which of the two was higher.
Results
Ninety-two consecutive patients (58±11 years, 50 males) were evaluated. Smokers (n=19) did not differ as regards 24-h ambulatory BP levels, glucose levels, renal function and left ventricular mass index when compared to non-smokers (n=73). However, higher levels of MSNA were recorded to smokers (73.16±13.42 vs. 61.04±18.10 bursts per 100 heartbeats, p<0.01). Furthermore, higher percentage of smokers recorded to have unattended BP values higher than attended (73.7% vs. 47.9% of them respectively, p=0.045). In particular, in smokers unattended BP was higher than attended by 10.07±6.7 mmHg, while in non-smokers unattended BP was lower than attended by 6.6±7.14 mmHg. No correlation was found between the MSNA and the differences observed in the two values resulting from the two different measurements of BP, maybe due to the small size of the sample.
Conclusions
Cigarette smoking is accompanied with higher sympathetic nervous system activation. Moreover, smokers exhibit higher unattended blood pressure values than normal measurements. The emerging hypothesis is that the stimulation of the sympathetic system causes this difference in measurements. A larger sample of patients is needed to fully determine the clinical significance of the above observation.

Abstract
OBJECTIVE The efficacy of renal sympathetic denervation (RDN) has been affirmed by a number of recent clinical studies, despite controversies in this field over the last five years. Therefore, it is of paramount importance that hypertension experts debate the merits of RDN by revealing and expressing their personal beliefs and perspectives regarding this procedure. METHODS A cross-sectional survey was conducted among Greek leaders of the Hypertension Excellence Centers with the use of a closed-type questionnaire specifically designed to elicit information and evaluate the respondent's views and perspectives about RDN efficacy, safety and ideal target patient population. RESULTS A total of 36 participants completed the survey. Based on the results, RDN was considered efficient (91.7%) and safe (94.5%), while the overwhelming majority of the participants felt confident in the long-term efficacy (88.9%) of the intervention and that it lacks reliable predictors of blood pressure response (94.5%). Patients with resistant (91.7%), ultra-resistant (94.4%), and uncontrolled hypertension (80.6%) were suggested as ideal candidates for RDN. Establishing a close co-operation between interventionalists and hypertension experts was considered essential to ensure the efficacy (97.2%) as well as the safety (97.3%) of the procedure. CONCLUSION The vast majority of Greek hypertension experts surveyed were convinced of the efficacy and safety of RDN based on the preponderance of available scientific and clinical data. Identification of the ideal patient group remains controversial. Respondents generally agreed on the necessity of building close collaborative relationships between interventionalists and hypertension experts in order to improve RDN clinical outcome.

Abstract
Abstract
Background/Introduction
Exaggerated blood pressure response (EBPR) during the exercise treadmill test (ETT) is often observed in individuals without known cardiovascular disease. Although it is generally considered as an abnormal response and a risk factor for hypertension development, its clinical significance remains controversial. On the other hand, regression of left ventricular hypertrophy (LVH) is independently associated with improved cardiovascular outcome.
Purpose
In this study we aimed to investigate the role of EBPR during exercise in LVH regression in hypertensive subjects over time.
Methods
1413 hypertensive subjects, (mean age 57±11 years), 51% males, with baseline office blood pressure (BP) 144/89mmHg were followed for a mean period of 6.4±3.0 years. At baseline and last follow-up visit all patients underwent office BP, laboratory tests and echocardiographical determination of left ventricular mass index (LVMI). At baseline, all subjects underwent treadmill exercise testing (Bruce protocol) in order to identify the presence of EBPR based on the systolic BP elevation at peak exercise (> or =210 mmHg for men and > or =190 mmHg for women). Main outcome variable was LVH Regression/prevention (LVH Regr/prev), defined as: LVH at baseline visit with normal LVMI values at last visit or absence of LVH at baseline and last visit. BP control was considered optimal when the mean of office BP measurements during follow-up was <140/90mmHg.
Results
46% of study population presented LVH Regr/prev during follow-up period. Cox-regression analysis, after adjustment for clinical and biochemical variables, revealed that low levels of baseline LVMI (HR=0.98, 95% CI 0.97–0.99, p<0.0001), absence of EBPR (HR=0.81, 95% CI 0.67–0.98, p=0.02) and optimal BP control during follow-up (HR=1.19, 95% CI 1.01–1.56, p=0.03) were independent predictors of LVH Regr/prev during follow-up.
Conclusions
Beyond optimal BP control, EBPR is a significant predictor of left ventricular mass changes overtime. Hence, ETT can provide clinical relevant information, including EBPR, which may help in the improvement of risk stratification of hypertensive subjects.

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.

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
