Psychological determinants of drug adherence and severity of hypertension in patients with apparently treatment-resistant vs. controlled hypertension.

PURPOSE: In a pilot study including 35 patients with apparently treatment-resistant hypertension (ATRH), we documented associations between psychological profile, drug adherence and severity of hypertension. The current study aims to confirm and expand our findings in a larger and more representative sample of patients with ATRH, using controlled hypertensive patients as the comparator. MATERIALS AND METHODS: Patients with ATRH were enrolled in hypertension centres from Brussels and Torino. The psychological profile was assessed using five validated questionnaires. Drug adherence was assessed by high-performance liquid chromatography-tandem mass spectrometry analysis of urine samples, and drug resistance by 24-hour ambulatory blood pressure was adjusted for drug adherence. RESULTS: The study sample totalised 144 patients, including 81 ATRH and 63 controlled hypertensive patients. The mean adherence level was significantly lower in the "resistant" group (78.9% versus 92.7% in controlled patients, p-value = .022). In patients with ATRH, independent predictors of poor drug adherence were somatisation, smoking and low acceptance level of difficult situations, accounting for 41% of the variability in drug adherence. Independent predictors of severity of hypertension were somatisation, smoking, more frequent admissions to the emergency department and low acceptation, accounting for 63% of the variability in the severity of hypertension. In contrast, in patients with controlled hypertension, the single predictors of either drug adherence or severity of hypertension were the number of years of hypertension and, for the severity of hypertension, alcohol consumption, accounting for only 15-20% of the variability. CONCLUSION: Psychological factors, mostly related to somatisation and expression of emotions are strong, independent predictors of both drug adherence and severity of hypertension in ATRH but not in controlled hypertensive patients.

This study included 144 patients with Apparently-Treatment Resistant (ATRH) or controlled Hypertension: Patients with ATRH were more often poorly adherent to antihypertensive treatment than controlled hypertensive patients.In patients with ARTH but not patients with controlled hypertension, psychological traits were strong, independent predictors of drug adherence and severity of hypertension, over and above demographic and health-related factors.In patients with ATRH, the tendency to somatize, i.e. expressing somatic symptoms that cannot be adequately explained by organic findings was the most potent predictor of both poor drug adherence and severity of hypertension.These patients also often presented alterations in the expression of emotions. It may be hypothesised that subjects who have difficulties identifying and expressing emotions with words will express them by physical complaints, and, in the mid-long term, might develop overt diseases.In addition to more classical lifestyle and drug management and irrespective of their drug adherence level, patients with ATRH may benefit in priority from psychological evaluation and interventions. However, this needs to be studied in an interventional trial in the future.

Knowledge on arterial hypertension in general population: Results from a community pharmacy screening program.

BACKGROUNDS AND AIMS: Hypertension is a risk factor for renal, cardiovascular and cerebrovascular diseases. It is responsible for a large proportion of overall morbidity and mortality every year. Hypertension-mediated organ damage is largely not reversible. For these reasons, prevention has primary importance: sensibilization of population on hypertension-related consequences is essential for therapeutic adherence and reduction of unhealthy lifestyle behaviour. This study aimed to evaluate awareness about hypertension among community pharmacies customers. METHODS AND RESULTS: A questionnaire about hypertension was collected by 2731 customers from 94 community pharmacies in North West Italy, during a hypertension screening program. Hypertension awareness was unsatisfactory in a large proportion of the sample, with only 15% of subjects having an overall good level of knowledge. Furthermore, lower awareness was associated to higher blood pressure values (132/79 ± 19/11 mmHg vs 128/78 ± 18/10 mmHg, p < 0.001) and subjects resulted hypertensive or uncontrolled despite antihypertensive therapy, presented worse questionnaire scores (4.7 ± 1.9 vs 4.9 ± 2.0, p = 0.03). CONCLUSION: Knowledge about hypertension is largely unsatisfactory among population. Community pharmacies may play as a setting for health education and hypertension screening.

Prevalence and characteristics of renal artery fibromuscular dysplasia in hypertensive women below 50 years old.

BACKGROUND: Renal fibromuscular dysplasia (FMD) is typically diagnosed in young hypertensive women. The 2014 European FMD Consensus recommended screening in all hypertensive women <30 yo. However, the prevalence of renal FMD in young/middle-aged hypertensive women remains unclear. The aim of this work was to assess the prevalence and characteristics of renal FMD in hypertensive women ≤50 yo. METHODS: We retrospectively included all consecutive women aged ≤50 years referred to our Hypertension Unit from 2014 to 2017 and collected standardized information on patient characteristics and screening modalities. RESULTS: Of 1083 incident hypertensive patients, 157 patients fitted with inclusion criteria. The prevalence of renal FMD varied between 3.2% in the whole sample and 7.5% in patients explored by CTA and/or MRA (n = 67). In the subgroup of patients ≤30 yo (n = 32), the corresponding figures were 3.1% and 5.6%. The yearly prevalence of FMD tended to increase over time, in parallel with increased use of CTA/MRA as a first-line imaging modality. Out of 5 patients with renal FMD, 2 were revascularized and 1 had extra-renal FMD. CONCLUSIONS: The prevalence of renal FMD in young/middle-aged hypertensive women is probably one order of magnitude higher than previously assumed, in the range of 3%-8%, depending on imaging modalities. While the diagnosis of FMD does not influence short-term management in all patients, it may allow close monitoring and prevention of complications of the disease over time. This analysis provides the rationale for a prospective, multicentre study aiming at determining the cost-effectiveness of systematic screening for renal FMD.

Assessment of a non-physician screening program for hypertension and cardiovascular risk in community pharmacies.

BACKGROUND AND AIMS: The strategic role of prevention in hypertension setting is well known but, with the only exception of annually events promoted by international scientific societies, no other screening campaigns are available. Aim of this study was to assess the feasibility of a non-physician pharmacy-based screening program and to describe the cardiovascular risk and the BP status of participating subjects. METHODS AND RESULTS: 2731 costumers participated to the screening program, answering to a questionnaire about personal cardiovascular risk and measuring their BP with an Omron HEM 1040-E. Since no threshold for hypertension diagnosis is currently available for community pharmacies BP measurements, we assessed high BP prevalence according to 3 different cut-offs (≥140/90, ≥135/85 and ≥ 130/80 mmHg) and compared normotensives and hypertensives on major cardiovascular risk factors. According to the proposed cut-offs, prevalence of hypertension was respectively of 31%, 45% and 59.5%, and it increased among younger subjects (31-65 y) when the lowest cut-offs were applied. High BP was found in a large percentage of subjects self-declared on-/not on-treatment (uncontrolled hypertensives) or normotensives (presumptive hypertensives) and among those not aware of their own BP values (presumptive hypertensives). Prevalence of CV risk factors was higher in hypertensives than in normotensives. CONCLUSIONS: Our findings demonstrated that a community pharmacy-based screening is feasible and attracts the interests of many subjects, improving awareness on their BP status. The screening was also showed to be useful in order to detect potentially uncontrolled and/or suspected new hypertensives, especially among young adults, to refer to general practitioners for confirmatory diagnosis or further evaluation.

Predictors of blood pressure control in patients with resistant hypertension after intensive management in two expert centres: the Brussels-Torino experience.

Background: Management of resistant hypertension (RHTN) is challenging and often implies the use of complex polypharmacy and interventional therapies. The main objectives of this study were (i) to describe the characteristics of patients with RHTN referred to two expert centres; (ii) to identify predictors of blood pressure (BP) control after intensive management. Methods: We reviewed electronic medical files of all patients referred for RHTN to the Brussels and Torino centres, and extracted detailed clinical data, informations on drug adherence and psychological profile. All patients with confirmed diagnosis of RHTN, according to office and ambulatory BP monitoring (ABPM) measurements, were considered eligible. Results: 313 patients (51% men; age: 56 ± 12 years; office BP 177/98 mmHg; 24-hour ABPM 153/90 mmHg) were included. At the end of follow-up (median: 2 years [1-4]), only 26% of patients (n = 81) reached BP control. When compared to patients remaining resistant, patients eventually controlled had lower pulse pressure (71 vs. 82 mmHg, p < 0.001), less often myocardial infarction (6% vs. 20%, p < 0.005) and showed a higher recourse to cognitive reappraisal as far as emotion regulation is concerned (4.8 ± 1.1 vs. 3.9 ± 1.2, p = 0.009; ERQ Questionnaire). In a multivariate analysis looking for predictors of controlled BP, only the psychological characteristic of cognitive reappraisal (i.e., changing one's thoughts about a potentially emotion-eliciting event) remained significant (OR 2.06 [1.10; 3.84], p = 0.02). Conclusions: Even in expert centres, only a minority of patients with RHTN reached BP control, irrespective of the centre involved or the interventions applied. Patients who eventually responded to therapy had lower arterial stiffness and less cardiac organ damage. Furthermore, besides vascular damage, the single predictor of BP control was the ability to modify the emotional impact of stressful situations.

Therapeutic drug monitoring-guided definition of adherence profiles in resistant hypertension and identification of predictors of poor adherence.

AIMS: Arterial hypertension is an important cardiovascular risk factor. A substantial proportion of patients show resistance to antihypertensive treatment but poor adherence to medication regimens is also a significant cause of treatment failure. In this context, therapeutic drug monitoring (TDM) could be useful. The objective of this study was to assess adherence to treatment in patients with resistant hypertension by TDM and to identify parameters that predict nonadherence. METHODS: Liquid chromatography tandem mass spectrometry was used to quantify a wide panel of antihypertensive drugs in human plasma to assess treatment compliance. Associations between TDM-determined adherence profiles, self-reported adherence and other patient-related clinical, anthropometric or demographic features were evaluated as potentially useful pre-TDM predictors of poor adherence. RESULTS: TDM was performed on 50 patients with suspected resistant hypertension: 24% of patients partially complied to treatment and 18% were nonadherent. No concordance was observed with questionnaire results, while nonadherence was associated with high diastolic blood pressure, high heart rate, previous onset of stroke and previous use of invasive treatments, including renal denervation or baroreceptor stimulation. CONCLUSIONS: This evidence highlights the high prevalence of poor adherence in patients with resistant hypertension and the need for caution in using invasive approaches. These preliminary data require validation in a larger cohort, to confirm the need for TDM in routine clinical practice.

Impact of psychological profile on drug adherence and drug resistance in patients with apparently treatment-resistant hypertension.

PURPOSE: Patients with apparent treatment-resistant hypertension (a-TRH) are often poorly adherent to drug treatment and have an unusual personal history and psychological profile. The aim of this study was to identify predictors of drug adherence and drug resistance in a cohort of patients with aTRH, with emphasis on psychological characteristics. METHODS: All patients with confirmed aTRH on standardized antihypertensive treatment were eligible. Drug adherence was assessed by drug dosages in urine using Liquid Chromatography coupled with tandem Mass Spectrometry (LC-MS/MS). Drug resistance was assessed by 24-hour ambulatory blood pressure adjusted for the number of antihypertensive drugs and for drug adherence. Psychological profile was assessed using a broad array of validated questionnaires. RESULTS: The analysis included 35 consecutive patients. The proportion of adherent, partly adherent and totally non-adherent patients was 29, 40 and 31%, respectively. In regression analysis, independent predictors of poor drug adherence were recent hospital admission for hypertension, a lower ability to put things into perspective when facing negative events and a higher tendency to somatize, accounting for 51% of variability in drug adherence. Independent predictors of treatment resistance were a higher recourse to the strategies of blaming others and oneself, accounting for 37% of variability in drug treatment resistance. CONCLUSION: In patients with aTRH, poor adherence is frequent but does not entirely account for treatment resistance. Psychological characteristics appear as strong predictors of both drug adherence and drug resistance. Our results suggest that therapeutic drug monitoring and psychological evaluation should be an integral part of assessment of patients with aTRH.

Evaluation of a short home blood pressure measurement in an outpatient population of hypertensives.

Current guidelines suggest the use of home blood pressure monitoring (HBPM) as a method complementary to ambulatory blood pressure monitoring (ABPM) for the identification of arterial hypertension. A cross-sectional study was conducted to evaluate the accuracy of a short HBPM schedule compared with ABPM, and to evaluate to what extent HBPM can replace ABPM. A total of 310 patients who performed ABPM in our hypertension clinic were enrolled between November 2011 and June 2015. They performed a 4-day HBPM schedule, with two readings in the morning and two readings at night. Results showed a moderate correlation between HBPM and ABPM (r = 0.59 for systolic blood pressure (SBP) and r = 0.72 for diastolic blood pressure (DBP)) and moderate diagnostic agreement (area under curve: 0.791 for SBP and 0.857 for DBP). No significant difference was found between first-day average and those of days 2-4. Diagnostic agreement between the two techniques was moderate, supporting the notion that HBPM cannot replace ABPM in the general population. However, we identified two HBPM thresholds, 123/75 and 144/87 mm Hg, through which subjects who may not require further ABPM can be identified.

Prevalence of erectile dysfunction in a cohort of Italian hypertensive subjects.

The aim of this study was to evaluate the prevalence of erectile dysfunction (ED) in a cohort of Italian hypertensive men and the association with clinical and biochemical data. The study involved 270 consecutive hypertensive subjects aged 40-70 years evaluated in Italian Hypertension Centers of six hospitals from Liguria and Piedmont. ED was assessed through the self-administered questionnaire of the International Index of Erectile Function. Clinical history with ongoing drug treatment, various clinical parameters, biochemical data and evidence about the presence of subclinical target organ damage was collected. Twenty-seven subjects refused to answer the questionnaire (10%). Among the 243 remained subjects, 123 presented ED (50.6%). ED was highly related to age, systolic blood pressure, pulse pressure, smoking status, statin therapy and kidney function. The addition of a thiazide diuretic to an inhibitor of the renin-angiotensin system significantly increased the prevalence of ED. The prevalence of ED increased in relation with the number of hypotensive drug classes taken by the patients. ED was highly prevalent in this cohort of Italian hypertensive subjects and was associated with other cardiovascular risk factors, such as age, smoking status and kidney function. The role of ED as an early marker of cardiovascular disease is discussed.

Multiple drug intolerance in antihypertensive patients: what is known and what is missing.

Drug allergy and intolerance are increasingly recognized as significant public health concerns, leading to adverse reactions in patients undergoing pharmacological treatments. Multiple drug intolerance syndrome (MDIS), characterized by adverse reactions to at least three different drug classes without a clear immunological mechanism, poses a substantial challenge, particularly in hypertensive patients. Despite its link to suboptimal adherence and uncontrolled blood pressure, MDIS in the context of hypertension remains insufficiently explored. This review synthesizes existing literature on MDIS, emphasizing clinical characteristics, pathogenesis, and psychiatric comorbidity. Furthermore, it delves into MDIS in the context of hypertension, highlighting the importance of a multidisciplinary approach in diagnosis and management, including innovative therapeutic strategies such as novel therapeutic algorithms or renal denervation. The review concludes by emphasizing the necessity for further research and clinical trials to enhance our understanding and address MDIS, especially in hypertensive patients.

Prevalence of Hyperkalemia and Familial Hyperkalemic Hypertension in 5100 Patients Referred to a Tertiary Hypertension Unit.

BACKGROUND: Hyperkalemia is a frequent electrolyte alteration whose prevalence varies widely, depending on the adopted cutoff, the setting (inpatients versus outpatients), and the characteristics of the study population. Familial hyperkalemic hypertension (FHH) is a rare cause of hypertension, hyperkalemia, and hyperchloremic metabolic acidosis. METHODS: In this retrospective observational study, we investigated the prevalence of hyperkalemia (serum K+ >5.2 mmol/L on 2 repeated measurements) in 5100 referred patients affected by arterial hypertension, the potential causes, and the associated cardiovascular risk profile. RESULTS: Overall, 374 (7.3%) patients had hyperkalemia. This was associated with drugs known to increase K+ levels (74.6%), chronic kidney disease (33.7%), or both (24.3%). Among the 60 patients with unexplained hyperkalemia, 3 displayed a clinical and biochemical phenotype suggestive of FHH that was genetically confirmed in 2 of them (0.04% in the entire cohort). FHH prevalence rose to 3.3% in patients with unexplained hyperkalemia and up to 29% (2/7) if they had serum K+>5.8 mmol/L. The genetic cause of FHH was a missense variant affecting the acidic motif of WNK1 in 1 family and a rare CUL3 splicing variant, whose functional significance was confirmed by a minigene assay, in another. Finally, we observed a significant association between hyperkalemia and the occurrence of cardiovascular events, metabolic syndrome, and organ damage, independent of potential confounding factors. CONCLUSIONS: The identification of hyperkalemia in patients with hypertension has prognostic implications. A timely diagnosis of FHH is important for effective management of hypertension, electrolyte imbalance correction with tailored treatment, and genetic counseling.

Management of Renovascular Hypertension and Renal Denervation in Patients with Hypertension: An Italian Nationwide Survey.

INTRODUCTION: Renovascular hypertension (RVH) remains underdiagnosed despite its significant cardiovascular and renal morbidity. AIM: This survey investigated screening and management practices for RVH among hypertensive patients in Italian hypertension centres in a real-life setting. Secondary, we analysed the current spread of renal denervation (RDN) and the criteria used for its eligibility. METHODS: A 12 item-questionnaire was sent to hypertension centres belonging to the European Society of Hypertension and to the Italian Society of Hypertension (SIIA) in Italy. Data concerning the screening and management of RVH and of RDN were analysed according to the type of centre (excellence vs non-excellence centres), geographical area and medical specialty. RESULTS: Eighty-two centres participated to the survey. The number of patients diagnosed in each centre with RVH and fibromuscular dysplasia during the last five years was 3 [1;6] and 1 [0;2], respectively. Despite higher rates of RVH diagnosis in excellence centres (p = 0.017), overall numbers remained unacceptably low, when compared to expected prevalence estimates. Screening rates were inadequate, particularly among young hypertensive patients, with only 28% of the centres screening for RVH in such population. Renal duplex ultrasound was underused, with computed tomographic angiography or magnetic resonance angiography reserved for confirming a RVH diagnosis (76.8%) rather than for screening (1.9-32.7%, according to patients' characteristics). Scepticism and logistical challenges limited RDN widespread adoption. CONCLUSIONS: These findings underscore the need for improving RVH screening strategies and for a wider use of related diagnostic tools. Enhanced awareness and adherence to guidelines are crucial to identifying renovascular hypertension and mitigating associated cardiovascular and renal risks.

The impact of the COVID-19 pandemic on blood pressure control in patients with treated hypertension-results of the European Society of Hypertension Study (ESH ABPM COVID-19 Study).

BACKGROUND: We aimed to determine the influence of coronavirus disease 2019 (COVID-19) pandemic on blood pressure (BP) control assessed by ambulatory blood pressure monitoring (ABPM). METHODS: Office BP and ABPM data from two visits conducted within a 9-15 months interval were collected from patients treated for hypertension. In the prepandemic group, both visits took place before, while in the pandemic group, Visit-1 was done before and Visit-2 during the pandemic period. RESULTS: Of 1811 collected patients 191 were excluded because they did not meet the required ABPM time frames. Thus, the study comprised 704 patients from the pandemic and 916 from the prepandemic group. Groups did not differ in sex, age, duration of hypertension, frequency of first line antihypertensive drug use and mean 24 h BP on Visit-1. The prevalence of sustained uncontrolled hypertension was similar in both groups. On Visit-2 mean 24 h BP, daytime and nighttime systolic BP and diastolic BP were higher in the pandemic compared to the prepandemic group ( P  < 0.034). The prevalence of sustained uncontrolled hypertension on Visit-2 was higher in the pandemic than in the prepandemic group [0.29 (95% confidence interval (95% CI): 0.26-0.33) vs. 0.25 (95% CI: 0.22-0.28), P  < 0.037]. In multivariable adjusted analyses a significant difference in BP visit-to-visit change was observed, with a more profound decline in BP between visits in the prepandemic group. CONCLUSIONS: This study using ABPM indicates a negative impact of the COVID-19 pandemic on BP control. It emphasizes the need of developing strategies to maintain BP control during a pandemic such as the one induced by COVID-19.

Endovascular Versus Medical Management of Atherosclerotic Renovascular Disease: Update and Emerging Concepts.

Atherosclerotic renovascular disease is the most frequent cause of renovascular hypertension and its prevalence increases with age and in specific subset of patients, such as those with end-stage chronic kidney disease, heart failure, and coronary artery disease. Besides hypertension, atherosclerotic renovascular disease is responsible for several clinical manifestations, including life-threatening conditions, such as recurrent flash pulmonary edema, rapidly progressive chronic kidney disease, or acute kidney injury. Atherosclerotic renovascular disease is usually part of a more diffuse atherosclerotic process and requires a combination therapy including antihypertensive, antiplatelet and lipid-lowering agents, as well as optimization of antidiabetic treatment, if needed. Besides medical therapy, percutaneous renal angioplasty was supposed to be the most effective therapy for atherosclerotic renovascular disease, by leading to blood flow restoration. However, despite an apparently solid rationale, several randomized clinical trials failed to confirm the favorable effects of percutaneous renal angioplasty on blood pressure control, kidney function, cardiovascular and renal outcomes, previously reported in observational, retrospective and single-center cohorts, switching off the enthusiasm for this procedure. Several studies' limitations may partly account for this failure, including heterogeneity of diagnostic techniques, overestimation of the degree of renal artery stenosis, inappropriate timing of revascularization, multiple protocol revisions, frequent crossovers, and most importantly exclusion of patients at higher likelihood to respond to angioplasty. The purpose of this review is to summarize studies' potential weaknesses and provide guidance to the clinician for identification of patients who may benefit most from revascularization.

Left atrial enlargement in essential hypertension: role in the assessment of subclinical hypertensive heart disease.

BACKGROUND: Arterial hypertension is a common cause of cardiac organ damage, inducing morphofunctional modifications involving left chambers. This is a retrospective study: it was designed to evaluate the additive clinical value of left atrial enlargement (LAe) assessment in the evaluation of cardiac organ damage. METHODS: A total of 814 (67% male; aged 50.7 ± 12 years, mean ± SD) essential hypertensive subjects underwent routinely to a complete and extensive clinical and echocardiographic evaluation. Left ventricular morphology, systolic and diastolic function and left atrial dimension (LAD; linear and volumetric) were evaluated. RESULTS: Prevalence of LAe varied between 6.2% and 52.1%, depending on the chosen criteria (left atrial diameter indexed for body surface area (BSA) vs left atrial volume (LAV) indexed for BSA - LAVi). LAVi showed to be the most sensitive parameter in order to detect it (sensitivity 96%, specificity 100%). Left ventricular hypertrophy (LVH) was present in about one fifth of our population (14% and 26%, considering indexation for BSA and for height(2.7)). Concentric remodelling (CR) was present in 27-35% of cases considering left ventricular mass indexation for BSA and for height(2.7), respectively. In one quarter of our population, LAe was the only echocardiographic sign of hypertension, independent of LVH and CR. CONCLUSIONS: LAV evaluation in hypertensive population can contribute to the identification of subjects affected by hypertensive heart disease other than the conventionally evaluated terms (LVH and CR).

Echocardiographic abnormalities in the assessment of cardiac organ damage in never-treated hypertensive patients.

Hypertension-related cardiac organ damage, other than left ventricular (LV) hypertrophy (LVH), has been described: in particular, concentric remodeling, LV diastolic dysfunction (DD), and left atrial (LA) enlargement are significantly associated with cardiovascular morbility and mortality in different populations. This study evaluated the prevalence of these latter morphofunctional abnormalities, in never-treated essential hypertensive patients and the role of such a serial assessment of hypertensive cardiac damage in improving cardiovascular risk stratification in these patients. A total of 100 never-treated essential hypertensive subjects underwent a complete clinical and echocardiographic evaluation. Left ventricular morphology, systolic and diastolic function, and LA dimension (linear and volume) were evaluated by echocardiography. Left ventricular hypertrophy was present in 14% of the patients, whereas concentric remodeling was present in 25% of the subjects. Among patients free from LV morphology abnormalities, the most frequent abnormality was LA enlargement (global prevalence 57%); the percentage of patients with at least one parameter consistent with DD was 22% in the entire population, but DD was present as the only cardiac abnormality in 1% of our patient. Left atrial volume indexed for body surface area was the most sensitive parameter in identifying hypertension-related cardiac modification. The global prevalence of cardiac alteration reached 73% in never-treated hypertensive patients. Left ventricular remodeling and LA enlargement evaluation may grant a better assessment of cardiac organ damage and cardiovascular risk stratification of hypertensive patients without evidence of LVH after routine examination.

Silent cerebrovascular damage and its early correlates in essential hypertensive patients.

This study tested the association between cognitive functions, cerebrovascular damage, and cerebrovascular reactivity in 71 essential young hypertensives (age matched) and 22 normotensives (age matched). They underwent ambulatory blood pressure monitoring, neurocognitive tests, cerebral magnetic resonance, and transcranial Doppler. Twenty-three percent of patients showed more than 10 white matter lesions and 8% showed none. No control subjects showed more than 10 white matter lesions and 90% of normal controls showed no lesions. Patients with more than 10 white matter alterations had longer hypertensive story and showed significant lower nocturnal blood pressure fall. Pulsatility index was correlated with the number of white matter lesions.

Comparison of nurse attended and unattended automated office blood pressure with conventional measurement techniques in clinical practice.

Accuracy in blood pressure measurement is critical for proper hypertension diagnosis and treatment in clinical practice. Automated office blood pressure (AOBP) can simplify the measurement process, reducing human error and minimizing the white-coat effect in the unattended mode. The aim of this study was to compare AOBP, both unattended and nurse attended, with conventional office and out-of-office blood pressure measurement techniques. Four different methods of blood pressure measurement were performed in a cohort of hypertensive patients: conventional office blood pressure (OBP), unattended automated office blood pressure (uAOBP), nurse attended automated office blood pressure (nAOBP), and home blood pressure monitoring (HBPM). uAOBP and nAOBP were conducted with the same rigorous standardized procedure. We enrolled 118 consecutive patients. nAOBP values were slightly higher than uAOBP ones (respectively 132.8/73.3 ± 19.4/12.9 and 129.2/71.1 ± 19.0/12.3 mmHg), even if the difference was influenced by order of execution of AOBP measurement. nAOBP was significantly lower than HBPM and OBP (mean values 135.2/80.9 ± 16.6/8.1 and 140.9/84.6 ± 18.7/10.8 mmHg, respectively). AOBP, either attended or unattended, provides lower values than conventional OBP. uAOBP and nAOBP values showed small differences, even if they are not completely interchangeable. This evidence reflects a lower white-coat effect, even in nurse attended technique, but is also due to a lower measurement error through the application of a rigorous standardized protocol.

Drug adherence and psychological factors in patients with apparently treatment-resistant hypertension: Yes but which ones?

The aim of the study was to assess drug adherence, as well as association of psychological factors with both drug adherence and severity of hypertension in two subtypes of patients with apparently treatment-resistant hypertension (ATRH): younger patients with uncomplicated hypertension (YURHTN) versus patients ≥60-year-old and/or with a history of cardio- or cerebrovascular complication (OCRHTN). Drug adherence was assessed in urine by targeted Liquid Chromatography-Mass Spectrometry. The severity of hypertension was assessed by 24-h ambulatory blood pressure adjusted for the number of antihypertensive drugs and for drug adherence. Psychological profile was assessed using five validated questionnaires. The proportion of totally non-adherent patients was three times higher (24.1 vs. 7.1%, P = 0.026) in the YURHTN (n = 54) than in OCRHTN subgroup (n = 43). Independent predictors of drug adherence in YURHTN were ability to use adaptive strategies, male sex and family history of hypertension, accounting for 39% of variability in drug adherence. In the same subgroup, independent predictors of severity of hypertension were somatization and lower recourse to planification, accounting for 40% of variability in the severity of hypertension. In contrast, in the OCRHTN subgroup, independent predictors of drug adherence and severity of hypertension were limited to the number of yearly admissions to the emergency room and the total number of prescribed drugs. In conclusion, poor drug adherence and altered psychological profiles appear to play a major role in younger patients with ATRH devoid of cardiovascular complication. This subgroup should be prioritized for chemical detection of drug adherence and psychological evaluation.

A structured physical activity program in an adolescent population with overweight or obesity: a prospective interventional study.

Obesity is a significant health problem, with increasing involvement of young population worldwide. The aim of this study was to evaluate the effects of 2 different types of physical exercise (resistance vs. combined aerobic-resistance) on cardiovascular and anthropometric profile of a sample of sedentary adolescents with overweight and obesity. After undergoing clinical, cardiovascular and anthropometric-metabolic evaluation (T0), subjects with overweight and obesity were randomized to a 6-month resistance or combined aerobic-resistance training program. Clinical, cardiovascular and anthropometric-metabolic evaluations were repeated after 6 months of training (T1) and after 3 months of detraining (T2). Thirty adolescents with overweight/obesity were enrolled and 20 subjects completed training program. A significant improvement in body composition was detected after 6 months, with a reduction of body mass index (32.1 [30.5 to 34.4] vs. 31.1 [29.6 to 33.4] kg/m2, p = 0.02) and adipose tissue (45.5 [41.1 to 49.7] vs. 41.6 [37.0 to 49.2] kg, p < 0.01). A reduction in diastolic blood pressure (75.5 ± 8.9 vs. 68.2 ± 6.4 mm Hg, p = 0.02) and pulse wave velocity (5.7 [5.1 to 5.9] vs. 5.2 [4.7 to 5.7] m/s, p = 0.04) was also observed. Persistence of the effect on the most important parameters was observed also after detraining period. In conclusion, regular physical exercise induces positive metabolic and cardiovascular effects, persisting even after brief discontinuation. Novelty: Physical exercise induces positive effect on cardiovascular risk profile. Positive effects persist also after brief discontinuation. Physical exercise reduces early signs of autonomic disfunction.
