ABSTRACT
Hypokalemia plays an important role in the diagnosis and management of primary aldosteronism (PA). While the hypokalemic variant of the disease accounts for about one third of all cases, little is known about the incidence of PA in hypokalemic populations. The IPAHK+ study is an epidemiological, cross-sectional trial to provide evidence on the incidence of PA in hypokalemic patients from a university hospital outpatient population. Recruitment of outpatients with hypokalemia≤3 mmol/l is carried out on a continuous referral-basis through an automated data delivery system. Up to an interim data closure, 66 patients underwent the study protocol. The mean age of the participants was 52.9±1.5 years with an equal sex ratio of 1:1 women to men, a mean potassium value of 2.78±0.31 mmol/l [1.8;3.0] and a prevalence of arterial hypertension of 72.7%. PA was diagnosed in 46.6% of all participants, all of whom had a history of hypertension. Incidence of PA increased continuously with decreasing potassium levels with proportions of 26.7%, 50% and 57.1% in the subgroups of 3.0 mmol/l (n=15), 2.8-2.9 mmol/l (n=22) and≤2.7 mmol/l (n=21), respectively. Prior to testing, 59.1% of all patients presented at least with one plausible other cause of hypokalemia. The incidence of PA in the investigated outpatient population was more than 4 out of 10 and inversely correlated with baseline potassium levels. Moderate or severe hypokalemia, regardless of its cause, should therefore prompt evaluation for PA in hypertensive individuals. Normotensive hypokalemic PA was not observed in this cohort.

Since the publication of the 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) Guidelines for the Management of Arterial Hypertension, several high-quality studies, including randomised, sham-controlled trials on catheter-based renal denervation (RDN) were published, confirming both the blood pressure (BP)-lowering efficacy and safety of radiofrequency and ultrasound RDN in a broad range of patients with hypertension, including resistant hypertension. A clinical consensus document by the ESC Council on Hypertension and the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on RDN in the management of hypertension was considered necessary to inform clinical practice. This expert group proposes that RDN is an adjunct treatment option in uncontrolled resistant hypertension, confirmed by ambulatory BP measurements, despite best efforts at lifestyle and pharmacological interventions. RDN may also be used in patients who are unable to tolerate antihypertensive medications in the long term. A shared decision-making process is a key feature and preferably includes a patient who is well informed on the benefits and limitations of the procedure. The decision-making process should take (i) the patient's global cardiovascular (CV) risk and/or (ii) the presence of hypertension-mediated organ damage or CV complications into account. Multidisciplinary hypertension teams involving hypertension experts and interventionalists evaluate the indication and facilitate the RDN procedure. Interventionalists require expertise in renal interventions and specific training in RDN procedures. Centres performing these procedures require the skills and resources to deal with potential complications. Future research is needed to address open questions and investigate the impact of BP-lowering with RDN on clinical outcomes and potential clinical indications beyond hypertension.

In secondary hypertension, elevated blood pressure is caused by a known and/or potentially treatable underlying disease.Although the prevalence of secondary hypertension depends on the patient population and the thoroughness of applied diagnostic approaches, arterial hypertension is classified in 90 to 95% as primary in nature. In young patients, individuals without a family history of hypertension, late onset of hypertension or worsening of a previous well-controlled hypertension as well as in patients who have a difficult to treat hypertension, the prevalence of secondary hypertension is significantly higher.Because the identification and the specific therapy of secondary hypertension may result in normalisation or improvement of elevated blood pressure in many cases, a targeted diagnostics is of great importance.
Key messagesThe prevalence of secondary hypertension is 5-10% of hypertensive patients (lower in the whole population, higher in patients with therapy-resistant hypertension).Patient history, physical examination, and laboratory results are very important to patients with suspected secondary hypertension to identify. After a preliminary screening, the assignment is made recommended for specialist medical clarification.Think about secondary hypertension In young patients, individuals without a family history of hypertension, late onset of hypertension or worsening of a previous well-controlled hypertension as well as in patients who have a difficult to treat hypertension.

There is strong evidence that sex chromosomes and sex hormones influence blood pressure (BP) regulation, distribution of cardiovascular (CV) risk factors and co-morbidities differentially in females and males with essential arterial hypertension. The risk for CV disease increases at a lower BP level in females than in males, suggesting that sex-specific thresholds for diagnosis of hypertension may be reasonable. However, due to paucity of data, in particularly from specifically designed clinical trials, it is not yet known whether hypertension should be differently managed in females and males, including treatment goals and choice and dosages of antihypertensive drugs. Accordingly, this consensus document was conceived to provide a comprehensive overview of current knowledge on sex differences in essential hypertension including BP development over the life course, development of hypertension, pathophysiologic mechanisms regulating BP, interaction of BP with CV risk factors and co-morbidities, hypertension-mediated organ damage in the heart and the arteries, impact on incident CV disease, and differences in the effect of antihypertensive treatment. The consensus document also highlights areas where focused research is needed to advance sex-specific prevention and management of hypertension.

Arterial hypertension is the most important contributor to the global burden of disease; however, disease control remains poor. Although the diagnosis of hypertension is still based on office blood pressure, confirmation with out-of-office blood pressure measurements (ie, ambulatory or home monitoring) is strongly recommended. The definition of hypertension differs throughout various guidelines, but the indications for antihypertensive therapy are relatively similar. Lifestyle adaptation is absolutely key in non-pharmacological treatment. Pharmacologically, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, calcium channel blockers, and diuretics are the first-line agents, with advice for the use of single-pill combination therapy by most guidelines. As a fourth-line agent, spironolactone should be considered. The rapidly evolving field of device-based therapy, especially renal denervation, will further broaden therapeutic options. Despite being a largely controllable condition, the actual rates of awareness, treatment, and control of hypertension are disappointingly low. Further improvements throughout the process of patient screening, diagnosis, treatment, and follow-up need to be urgently addressed.

Extensive evidence demonstrates that lowering blood pressure can substantially reduce the risk of atherosclerotic cardiovascular disease and death.In light of the latest 2018 European Society of Cardiology/European Society of Hypertension Joint Guidelines, we summarize the current recommendations about lifestyle intervention strategies, pharmacotherapy, and device-based treatments for the management of arterial hypertension. Special attention is given to direct effects exerted by some antihypertensive drugs targeting vascular wall cell components that are involved in the pathogenesis of atherosclerosis.

May Measurement Month (MMM) is an international screening campaign for arterial hypertension initiated by the International Society of Hypertension and endorsed by the World Hypertension League. Its aim is to raise the awareness of elevated blood pressure (BP) in the population worldwide. The goal of the present analyses is to assess the results obtained during three years of this campaign in Switzerland. Swiss data from MMM17 to MMM19 campaigns were used. BP and a questionnaire for basic demographic and clinical information were recorded for each participant. BP measurements and definition of arterial hypertension followed the standard MMM protocol. To assess BP control, European Society of Hypertension 2018 thresholds of <140/90â mmHg were used. Overall, 3635 participants had their BP measured, including 2423 women (66.7%) and 1212 (33.3%) men. More than half of the data came from pharmacies during MMM18 and MMM 19 campaigns. The difference in BP between pharmacies and other screenings sites was small. Overall, prevalence and awareness rates were 32.7% and 72.3%, respectively. Of those on medication, 60.9% were controlled, and of all hypertensive patients, 39.4% had controlled BP. In Switzerland, the prevalence of hypertension based on a 3-year awareness campaign was similar to previous epidemiological data within the country. One third of the population screened had hypertension, two thirds were aware of it, and less than half had controlled BP.
ABSTRACT
A large number of cardiovascular events occur in seemingly healthy individuals. Atherosclerosis imaging can improve the outcome and treatment regime of such subjects. We aim to assess the predictive value of atherosclerosis imaging beyond traditional risk calculators in subjects aged 40-65 years. We compared PROCAM, SCORE and FRAM with carotid ultrasound (total plaque area, TPA) and arterial age (AA) was calculated in subjects without known cardiovascular diseases. Follow-up was obtained by phone or mail. In 2842 subjects (age 50 ± 8, 38% women) 154 (5.4%) cardiovascular events occurred (ASCVD: 41 myocardial infarctions, 16 strokes or TIA, 21 CABG, 41 PTCA, 35 coronary artery disease defined by invasive angiography) during a mean follow-up time of 5.9 (1-12) years. PROCAM risk was 5 ± 6%, SCORE risk 1.3 ± 1.6% and FRAM 10 ± 6%. Both for the primary outcome (AMI, STROKE/TIA, CABG) and the secondary outcome (adding CAD and PTCA) hazards increased significantly for TPA tertiles and AA groups between 1.4 (0.1-16.1) and 21.4 (2.8-163.6) after adjustment for risk factors (age, smoke, sex, systolic BP, lipids, BMI, medication in Model 1) and after adjustment for results from PROCAM, SCORE and FRAM (Model 2). Model performance was statistically improved regarding model fit in all models using TPA and AA. Net reclassification improvement (NRI) for PROCAM and SCORE using TPA tertiles or AA age groups increased significantly between 30% to 48%. TPA and AA added prognostic information to conventional risk equations, supporting the assessment of ASCVD risk with carotid ultrasound in subjects aged 40-65 years.

BACKGROUND: Vascular dysfunction is considered to spur the progression of cardiovascular disease in hemodialysis (HD) patients. Whether the HD procedure itself contributes to vascular dysfunction remains incompletely investigated. The present study sought to comprehensively assess the effects of HD on arterial and venous function along with concomitant changes in blood volume (BV). METHODS AND RESULTS: We determined BV with high-precision, automated carbon monoxide-rebreathing, arterial stiffness using applanation tonometry and intrinsic microvascular function via retinal vessel analysis prior to and after conventional 4-hour HD in fasting-controlled conditions in 10 patients. All HD patients were non-smokers and non-obese (body mass indexâ¯=â¯22.8⯱â¯2.8â¯m·kg-2). Hypertension (70%), coronary artery disease (40%) and diabetes mellitus (20%) were the most prevalent comorbidities. Prior to HD, all patients presented with hypervolemia (+2208⯱â¯1213â¯ml). HD decreased body weight (-1.72⯱â¯1.25â¯kg, Pâ¯=â¯0.002) and plasma volume (-689⯱â¯566â¯ml, Pâ¯=â¯0.004), while hematocrit (Hct) was concomitantly increased (+4.8⯱â¯4.5%, Pâ¯=â¯0.009). HD did not affect large elastic artery stiffness, as determined by carotid-femoral pulse wave velocity (Pâ¯=â¯0.448) and carotid distensibility (Pâ¯=â¯0.562). In contrast, flicker light-induced retinal venular dilation was reduced by three-fourths after HD (-2.4⯱â¯1.7%, Pâ¯=â¯0.039), in parallel to increased retinal venular diameter (+11.2⯱â¯4.9⯵m, Pâ¯=â¯0.002). In regression analyses, a negative association was observed between HD-induced changes in Hct and retinal venular dilation (râ¯≥â¯-0.89, Pâ¯≤â¯0.045). CONCLUSION: Conventional HD resulting in substantial plasma volume removal do not alter large artery elastic properties, whereas intrinsic microvascular venular dilator function is markedly impaired, an effect directly associated with the increase in hemoconcentration.

Aims: Retinal vessel analysis (RVA) represents a novel, non-invasive, and reliable method to study the microcirculation in the eye. The goal of this study was to assess the extent of retinal microvascular dysfunction in patients with chronic heart failure (CHF) compared to controls and established measures of vascular function. Methods and results: In this prospective, single-centre, observational study, 74 patients with compensated CHF (mean age 63.5 ± 11.2 years, 32% female, mean left-ventricular ejection fraction 37 ± 12.8%), 74 patients with cardiovascular risk factors (CVRF; 64.1 ± 12.7 years, 34% female), and 74 healthy controls (HC; 57.8 ± 14.2 years, 35% female) were included. The primary endpoint, flicker-induced dilatation of retinal arterioles (FIDart), was significantly reduced in patients with CHF compared to CVRF and HC (mean FIDart 0.9 ± 0.2 vs. 2.3 ± 0.3 and vs. 3.6 ± 0.3%, respectively, both P < 0.001 before and after propensity score-weighted analysis). Similar differences were seen for venular FID. FIDart was less impaired in patients with dilated compared to ischaemic cardiomyopathy. No significant differences were observed for arteriovenous ratio and flow-mediated dilatation. Impaired FIDven was associated with echocardiographically estimated systolic pulmonary artery pressure and left atrial volume index. Conclusion: Retinal microvascular dilatation in response to flicker light is impaired in CHF. RVA may represent a new and useful method to non-invasively monitor microvascular abnormalities in heart failure in an easy and standardized way without the use of radiation.

BACKGROUND/AIMS: Despite availability of a broad spectrum of blood pressure (BP)-lowering drugs many hypertensive patients do not attain BP goals. We aimed to evaluate the influence of home blood pressure monitoring (HBPM) on patient's awareness and attainment of BP goals under antihypertensive treatment with irbesartan alone or in combination with hydro-chlorothiazide. METHODS: In total, 1,268 patients with arterial hypertension were enrolled in the Factors Influencing Results in anti-hypertenSive Treatment (FIRST) study by 348 general practitioners and internal medicine specialists across Switzerland. Patients selected for HBPM received detailed information and training on BP self-management. The study endpoints included patient's awareness and attainment of BP goals, and the efficacy and tolerability of antihypertensive treatment at 3 months. RESULTS: Overall, the mean age was 61±13 years and 616 (49%) were women. The mean systolic/diastolic BP was 161±17/96±11 mmHg, and 239 (19%) patients had diabetes mellitus. 758 (60%) patients were instructed to use HBPM. Both the proportion of patients aware of their BP goals (81% vs. 70%; p< 0.001) and the percentage of patients reaching their BP goal (64% vs. 57%; p=0.028) were higher in those with vs. without HBPM. The mean reduction in systolic/diastolic BP was 23.8/13.2 mmHg. Only 35 (3.0%) patients discontinued antihypertensive therapy. CONCLUSION: In a large Swiss cohort of patients with arterial hypertension, information and training on BP self-measurement and direct involvement of patients by using HBPM led to improvement in BP control. Treatment with irbesartan alone or in combination with hydrochlorothiazide was well tolerated and markedly reduced BP.

Treatment-resistant hypertension, or resistant hypertension, is defined as blood pressure that remains above target despite concurrent use of at least three antihypertensive agents from different classes at optimal doses, one of which should be a diuretic. Important considerations in the diagnosis of treatment-resistant hypertension include the exclusion of pseudoresistance and the evaluation of potential secondary causes of hypertension and of concomitant conditions that maintain high blood pressure. The ability to diagnose true treatment-resistant hypertension is important for selection of patients who may be appropriately treated with an invasive therapy. Currently, there are three interventional approaches to treat resistant hypertension, namely: (1) reduction of the activity of the sympathetic nervous system by renal nerve ablation, (2) stimulation of baroreceptors and (3) creation of a peripheral arterial venous anastomosis. This review focuses on the rationale behind these invasive approaches and the clinical results.

OBJECTIVE: To determine whether intraocular treatment with vascular endothelial growth factor (VEGF) inhibitors change systemic endothelial function (EF) in patients with neovascular age-related macular degeneration (AMD). METHODS: In this prospective, randomized, 2-center, double-masked controlled interventional trial, patients with neovascular and dry AMD were enrolled. Eligible neovascular AMD patients received 2 intravitreal loading doses of either ranibizumab 0.5 mg or bevacizumab 1.25 mg at 4-week intervals and were subsequently followed every 4 weeks and treated according to a pro re nata regime for up to 1 year. Patients with dry AMD served as controls. The primary endpoint was the change in EF assessed by flow-mediated dilatation (FMD) after 2 months of treatment with VEGF inhibitors in patients with AMD compared to patients with dry AMD. FMD was assessed with B-mode high-resolution ultrasonography of the left brachial artery. RESULTS: 24 patients with neovascular AMD and 26 patients with dry ADM were included in the trial. Treatment with VEGF inhibitors did not significantly change FMD (from 4.7 ± 2.4 to 3.9 ± 1.9% after 8 weeks, p = 0.07, and to 5.1 ± 2.0% after 1 year; p = 0.93 vs. baseline, respectively). CONCLUSIONS: EF did not significantly differ between patients with neovascular AMD treated with intravitreal VEGF inhibition and patients with dry AMD.

BACKGROUND: The present study evaluated the predictive value of renal resistive index (RI) for renal function and blood pressure (BP) outcome in hypertensive patients with unilateral atherosclerotic renal artery stenosis submitted to successful revascularization. METHODS: In 158 hypertensive patients with atherosclerotic renal artery stenosis RI was acquired. Twelve months after revascularization, they were classified on the basis of renal function and BP outcome as benefit (BP < 140/90 mmHg or diastolic BP reduction > 15 mmHg with the same of reduced drugs; decrease in glomerular filtration rate > 20%), or failure. RESULTS: Regarding renal function outcome, RI in the stenotic and in the contralateral kidney were significantly higher in patients with failure (n = 20) than in those with benefit (0.72 ± 0.11 vs 0.61 ± 0.11 and 0.76 ± 0.08 vs 0.66 ± 0.09, p < 0.05). Among different cutpoints generated, RI in the contralateral kidney >0.73 provided the largest area under the curve (0.77), and the highest sensitivity (80%) and specificity (72%). In the multivariate logistic regression analysis, RI in the contralateral kidney >0.73 was an independent predictor of a failure in renal function outcome.Regarding BP outcome, patients with no benefit from revascularization (n = 60) had similar RI in the stenotic and contralateral kidney (p = ns), but presented higher pulse pressure, albuminuria and hypertension duration in comparison to patients with improved BP control. CONCLUSIONS: RI in the contralateral kidney is an independent predictor of renal function outcome after successful revascularization in hypertensive patients with unilateral atherosclerotic renal artery stenosis, whereas it is not able to predict blood pressure outcome.

AIMS: Catheter-based renal nerve ablation (RNA) using radiofrequency energy is a novel treatment for drug-resistant essential hypertension. However, the local endothelial and vascular injury induced by RNA has not been characterized, although this importantly determines the long-term safety of the procedure. Optical coherence tomography (OCT) enables in vivo visualization of morphologic features with a high resolution of 10-15 µm. The objective of this study was to assess the morphological features of the endothelial and vascular injury induced by RNA using OCT. METHODS AND RESULTS: In a prospective observational study, 32 renal arteries of patients with treatment-resistant hypertension underwent OCT before and after RNA. All pre- and post-procedural OCT pullbacks were evaluated regarding vascular changes such as vasospasm, oedema (notches), dissection, and thrombus formation. Thirty-two renal arteries were evaluated, in which automatic pullbacks were obtained before and after RNA. Vasospasm was observed more often after RNA then before the procedure (0 vs. 42%, P < 0.001). A significant decrease in mean renal artery diameter after RNA was documented both with the EnligHTN (4.69 ± 0.73 vs. 4.21 ± 0.87 mm; P < 0.001) and with the Simplicity catheter (5.04 ± 0.66 vs. 4.57 ± 0.88 mm; P < 0.001). Endothelial-intimal oedema was noted in 96% of cases after RNA. The presence of thrombus formations was significantly higher after the RNA then before ablation (67 vs. 18%, P < 0.001). There was one evidence of arterial dissection after RNA with the Simplicity catheter, while endothelial and intimal disruptions were noted in two patients with the EnligHTN catheter. CONCLUSION: Here we show that diffuse renal artery constriction and local tissue damage at the ablation site with oedema and thrombus formation occur after RNA and that OCT visualizes vascular lesions not apparent on angiography. This suggests that dual antiplatelet therapy may be required during RNA.

INTRODUCTION: There is potential for improvement in the care of cardiovascular diseases in Switzerland, particularly when it comes to achieving target values defined in guidelines. Adherence scores such as the SGED score for diabetic care established in Switzerland can help to reduce the evidence-performance gap. The CARE score presented here is an adherence score that validly reflects the quality of care for patients with a cardiovascular risk using process and outcome indicators.

AIMS: Many cardiovascular events occur in seemingly healthy individuals.We set out to assess the predictive value of atherosclerosis imaging in combination with cardiovascular risk calculators in subjects aged 40-65 years. METHODS: We compared PROCAM (PROspective CArdiovascular Münster study), SCORE (Systematic COronary Risk Evaluation) and SCORE2 with carotid ultrasound (total plaque area, TPA) in subjects without cardiovascular disease. In this prospective cohort study, follow-up was obtained by phone or mail from patients; or from clinical records, if needed. RESULTS: In 2842 subjects (mean age 50±8 years; 38% women), cardiovascular events occurred in 154 (5.4%) of them over an mean follow-up period of 5.9 (range 1-12) years, specifically: 41 cases of AMI (myocardial infarction), 16 strokes, 21 CABG (coronary artery bypass grafting), 41 PTCA (percutaneous transluminal coronary angioplasty) and 35 CAD (coronary artery disease). Mean PROCAM risk was 5±6%, mean SCORE risk was 1.3±1.6% and mean SCORE2 risk was 5±3%. Both for the primary outcome (major adverse cardiovascular events, MACEs, i.e. AMI + strokes) and the secondary outcome (atherosclerotic cardiovascular disease, ASCVD, i.e. MACEs + CABG + CAD + PTCA), hazards increased significantly for TPA tertiles and SCORE2 post-test risk between 6.7 to 12.8 after adjustment for risk factors (age, smoke, sex, systolic blood pressure, lipids, medication) and after adjustment for results from PROCAM, SCORE and SCORE2. Model performance was statistically improved regarding model fit in all models using TPA. Net reclassification improvement for SCORE2 with TPA post-test risk increased significantly by 24% for MACEs (p = 0.01) and 39% for ASCVD (p <0.0001). CONCLUSIONS: Integration of TPA post-test risk into SCORE2 adds prognostic information, supporting the use of carotid ultrasound when assessing ASCVD risk in subjects aged 40-65 years.

AIMS: The HEYMANS study observed patients receiving evolocumab as part of routine clinical hyperlipidemia management. It was designed to capture data on clinical parameters relevant to health authorities and physicians. METHODS: This was a European multi-country observational cohort serial chart review study; data on the Swiss cohort are reported here. Patients were prescribed evolocumab as per the Swiss reimbursement criteria in force at the time and were invited chronologically. The study consisted of a 6-month period prior to initiation of evolocumab, a 12-month core observation period (entered by 75 patients, completed by 74 patients), and an 18-month extended observation period (entered by 40 patients, completed by 34 patients). The primary objective was to describe the clinical characteristics of patients receiving evolocumab. Secondary objectives included to describe lipid levels, evolocumab use, and patterns of use of other lipid-lowering therapies (LLT, that is, statins and/or ezetimibe) over time. The study was conducted in the Swiss cohort between May 2017 and June 2021. RESULTS: Patients who received evolocumab in Swiss routine practice mostly were in secondary prevention (93%) and had a history of statin intolerance (85%) with 53% receiving no background LLT. One-third had familial hypercholesterolemia. Patients initiated evolocumab at a median low-density lipoprotein cholesterol (LDL-C) of 3.6 mmol/L, which decreased by 54% within 3 months to 1.6 mmol/L and was stable thereafter. Overall, 61% achieved the LDL-C goal of <1.4 mmol/L with more patients attaining this goal when they received evolocumab with a statin and/or ezetimibe (84%) compared to 41% when receiving evolocumab alone. An LDL-C reduction of ⩾50% was achieved by 85% of patients. Persistence with evolocumab at 12 months was 85%. CONCLUSION: In Swiss clinical practice, evolocumab was mainly prescribed to patients with very high cardiovascular risk, who had very high LDL-C levels. Most patients continued to use evolocumab throughout the study period. In these patients, LDL-C was reduced by >50% within 3 months and LDL-C reductions were maintained over time. Guideline-recommended LDL-C goals for this very high-risk cohort were more frequently attained in patients receiving a combination of statin and/or ezetimibe and evolocumab.
