Abstract
In treated hypertensive patients, there is a substantial residual cardiovascular (CV) risk that cannot be assessed by the available prediction models. This risk can be associated with subclinical organ damage, such as increased left ventricular mass (LVM) and arterial stiffness. However, it remains unknown which of these two CV markers better predicts coronary artery disease (CAD). A prospective cohort study was used to answer the above question. The study sample consisted of 1033 patients with hypertension (mean age 55.6 years, 538 males) free of CAD at baseline, who were followed for a mean period of 6 years. At baseline, all subjects underwent a complete echocardiographic study and pulse wave velocity (PWV) measurement. Hypertensive individuals who developed CAD (2.8%) compared to those without CAD at follow-up, had a higher baseline LVM index (by 16.7 g/m2, p < 0.001), higher prevalence of left ventricular hypertrophy (LVH) (21% greater, p = 0.027) and greater prevalence of high PWV levels at baseline (21% greater, p = 0.019). Multivariate Cox regression analysis revealed that baseline age >65 years (HR = 2.067, p = 0.001), male gender (HR = 3.664, p = 0.001), baseline chronic kidney disease (HR = 2.020, p = 0.026), baseline diabetes mellitus (HR = 1.952, p = 0.015) and baseline LVH (HR = 2.124 p = 0.001) turned out to be independent predictors of CAD, whereas high PWV levels were not. LVH proved to be an independent prognosticator of CAD in contrast to arterial stiffness that was not related to CAD after accounting for established confounders. Therefore, LVM can reliably help physicians to identify high-risk hypertensives in whom an intensified therapeutic management is warranted.

Impact of renal sympathetic denervation on cardiac magnetic resonance-derived cardiac indices in hypertensive patients - A meta-analysis. J Cardiol 2021; 78:314-321. [PMID: 34088560 DOI: 10.1016/j.jjcc.2021.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 03/20/2021] [Accepted: 04/09/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Renal sympathetic denervation (RDN) is a safe device-based option for the treatment of hypertension although current guidelines do not recommend its use in routine clinical practice. In this meta-analysis, we investigated the effects of RDN in cardiac magnetic resonance (CMR)-derived cardiac indices. METHODS This meta-analysis was performed in accordance with the PRISMA statement. A comprehensive systematic search of MEDLINE database and Cochrane library through to January 2021 was performed. The inclusion criteria were studies that enrolled patients undergoing RDN in whom CMR data were provided for left ventricular end-diastolic volume indexed to body surface area (BSA) (LVEDVI), left ventricular end-systolic volume indexed (LVESVI), left ventricular mass indexed (LVMI), and left ventricular ejection fraction (LVEF) pre and post RDN. A random effects model was used for the analyses. RESULTS Our search strategy revealed 9 studies that were finally included in the meta-analysis (n=300 patients, mean age: 60 years old, males: 59%). Compared to control group, RDN patients showed significantly lower values in the attained volumes (LVEDVI: -6.70 ml/m2, p=0.01; LVESVI: -3.63 ml/m2, p=0.006). Moreover, RDN group achieved a statistically significant higher attained LVEF (3.49%, p=0.01). A non-significant difference was found in the attained LVMI between RDN and control groups (-2.59 g/m2, p=0.39). Compared to pre-RDN values, RDN reduces significantly the LVMI, the LVEDVI, and the LVESVI while a non-significant change of LVEF was found. CONCLUSIONS In conclusion, the current study demonstrates the potential beneficial role of RDN in CMR-derived cardiac indices that reflect adverse remodeling. However, large, randomized studies are needed to elucidate the role of RDN in cardiac remodeling in hypertension, heart failure, and other clinical settings.

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
The aim of this study was to evaluate several sociodemographic, lifestyle, and clinical characteristics of the IKARIA study participants and to find healthy aging trajectories of multimorbidity of Ikarian islanders. During 2009, 1410 people (aged 30+) from Ikaria Island, Greece, were voluntarily enrolled in the IKARIA study. Multimorbidity was defined as the combination of at least two of the following chronic diseases: hypertension; hypercholesterolemia; diabetes; obesity; cancer; CVD; osteoporosis; thyroid, renal, and chronic obstructive pulmonary disease. A healthy aging index (HAI) ranging from 0 to 100 was constructed using 4 attributes, i.e., depression symptomatology, cognitive function, mobility, and socializing. The prevalence of multimorbidity was 51% among men and 65.5% among women, while the average number of comorbidities was 1.7 ± 1.4 for men and 2.2 ± 1.4 for women. The most prevalent chronic diseases among men with multimorbidity were hypertension, hypercholesterolemia, and obesity while among women they were hypertension, hypercholesterolemia, and thyroid disease. Multimorbidity was correlated with HAI (Spearman’s rho = −0.127, p < 0.001) and for every 10-unit increase in HAI, participants had 20% lower odds of being multimorbid. Multimorbidity in relation to HAI revealed a different trend across aging among men and women, coinciding only in the seventh decade of life. Aging is usually accompanied by chronic diseases, but multimorbidity seems to also be common among younger adults. However, healthy aging is a lifelong process that may lead to limited co-morbidities across the lifespan.

Abstract
BACKGROUND High blood pressure (BP) is a leading risk factor for coronary artery disease and other major cardiovascular events. OBJECTIVE Blood pressure variability (BPV), ambulatory arterial stiffness index (AASI) and ankle- brachial index (ABI) have been proposed as indices that can improve risk stratification for an adverse cardiac outcome. However, their utility in the setting of acute coronary syndromes (ACS) is unclear. METHODS The ACS-BP study is a single-centre observational cohort study designed to investigate the prognostic role of haemodynamic load and arterial stiffness indices for cardio-renal outcomes in patients with acute myocardial infarction (AMI). All consecutive patients admitted with a diagnosis of acute AMI with or without ST segment elevation were screened for inclusion in the study. The management of AMI will follow current guidelines. RESULTS AND DISCUSSION Data from baseline clinical and laboratory parameters during their hospitalization were collected. The haemodynamic load of each patient was determined by clinical BP values as well as 24-h ambulatory BP monitoring. The AASI was calculated from the raw 24-h BP data and ABI was measured after the third day of hospitalization using a certified device. Patients were followed-up for 12 months in order to collect data for hard cardiovascular and renal endpoints. CONCLUSION The study results should clarify the role of these non-invasive tools in secondary risk stratification of such patients.

Abstract
Objectives: The COVID-19 pandemic has led to major adjustments in health care systems and significantly affected medical education. Accordingly, our mentoring program MeCuM-Mentor had to expand its virtual elements, in order to continue to meet the needs for mentoring at the medical faculty of the Ludwig-Maximilians-University Munich. Methods: Here we report on our recently implemented online formats to facilitate training for currently coached peer mentors, as well as the introduction of an online consultation hour and a new social mentoring event called PubQuiz. Results: First results demonstrated feasibility of the above-mentioned virtual formats, which were positively rated by the participants in small voluntary evaluation questionnaires. Utilization rates indicate existing need for mentoring during the pandemic. In addition, the new event PubQuiz promotes social interaction among peers during isolation due to COVID-19. Conclusion: With the transition to online formats, mentoring at the Medical Faculty could be continued during COVID-19. The newly introduced mentoring event PubQuiz will be repeated. However, it remains unclear to what extent online formats can replace in-person one-to-one mentoring conversations or peer mentoring meetings.

Abstract
BACKGROUND Primary aldosteronism is one of the most common causes of secondary hypertension. Patients with this endocrine syndrome are at increased cardiovascular risk, higher than hypertensive individuals with equal blood pressure levels. OBJECTIVES The study aimed to thoroughly present and critically discuss the novel insights into the field of primary aldosteronism, focusing on the clinically meaningful aspects. METHOD We meticulously evaluated existing data in the field of primary aldosteronism in order to summarize future perspectives in this narrative review. RESULTS Novel data suggests that a subclinical form of primary aldosteronism might exist. Interesting findings might simplify the diagnostic procedure of the disease, especially for the localization of primary aldosteronism. The most promising progress has been noted in the field of the molecular basis of the disease, suggesting new potential therapeutic targets. CONCLUSION Several significant aspects are at early stages of evaluation. Future research is essential to investigate these well-promising perspectives.

Abstract
PurposeThe ultimate aim of this study is to investigate how health information needs’ satisfaction actually makes a difference to the patients' management of a chronic clinical condition. The literature falls short of providing evidence on the interaction between patients' health information seeking behaviour and the successful management of a clinical condition. On the other hand, patient education and good information seeking practices are deemed necessary for hypertension management daily decisions.Design/methodology/approachA specially designed questionnaire study was developed: The survey design was informed by the information seeking behaviour model of Wilson for studying hypertension patients' information needs, information resources and obstacles patients face while seeking hypertension-related information. Moreover, clinical information was collected in order to make associations and inference on the impact of information seeking on patients' clinical outcomes.FindingsThe study included 111 patients submitted to the outpatient hypertension clinic of a university hospital in Athens for a 24-h ambulatory blood pressure measurement (ABPM). The analysis showed that those reporting higher satisfaction level of their information needs achieved lower values in ABPM (ABPM<130/80mmHg, p = 0.049). Stepwise the logistic regression analysis revealed three independent factors to predict the possibility of being optimally treated (ABPM<130/80mmHg). Dipping status (OR: 14.052, 95% CI: 4.229–46.688, p = 0.0001) patients with high satisfaction level of their disease (OR: 13.450, 95% CI: 1.364–132.627, p = 0.026) and interpersonal relationships were used as the main source of information (OR: 1.762, 95% CI: 1.024–3.031, p = 0.41).Originality/valueHypertensive patients with high satisfaction level of information achieve better disease control. Among different sources of information, interpersonal relationships emerge as the most appropriate factor for patients' disease control.

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
Background
The dietary approaches to stop hypertension (DASH) diet is recognized as an effective dietary intervention to reduce blood pressure (BP). However, among randomized controlled trials (RCTs) investigating the DASH diet mediated BP reduction,there are significant methodological and clinical differences.
Purpose
The purpose of this study was to comprehensively assess the effect of the DASH diet on BP levels in adults with and without hypertension, accounting for underlying methodological and clinical confounders.
Methods
We systematically searched Medline and the Cochrane Collaboration Library databases and identified 30 RCTs (n=5,545 participants) that investigated the BP effects of the DASH diet compared to a control diet in hypertensive and non-hypertensive adults. Both random-effects and fixed-effect models were used to calculate the mean attained systolic BP (SBP) and diastolic BP (DBP) differences during follow-up. Subgroup and meta-regression analyses were also conducted.
Results
The DASH diet reduced SBP and DBP significantly more compared to the control diet (difference in means: −3.2 mm Hg; 95% CI: −4.2, −2.3; P<0.001, and −2.5 mm Hg; 95% CI: −3.5, −1.5; P<0.001, respectively). Hypertension status did not modify the effect on BP reduction. The DASH diet compared to the control diet reduced SBP levels to a higher extent in trials with sodium intake >2,400 mg/day compared to trials with sodium intake ≤2,400 mg/day, while both SBP and DBP were reducedmore in trials with mean age <50 years compared to trials of older participants. The quality of evidence was rated as moderate forboth outcomes according to the Grading of Recommendations, Assessment, Development and Evaluation approach.
Conclusion
The adoption of the DASH diet was accompanied by significant BP reduction in adults with and without hypertension, while higher daily sodium intake and younger age enhanced the BP-lowering effect of the intervention. This meta-analysis was registered in the International Prospective Register of Systematic Reviews as CRD42019128120.

Abstract
Abstract
Background
At present, few data are available on the prognosis of hypertensive emergencies and urgencies admitted to Emergency Departments (ED). The aim of our study was to evaluate the incidence of total and cardiovascular events during follow-up in hypertensive patients admitted in 2 ED in Italy and Greece with hypertensive emergencies or urgencies.
Methods
Medical records of patients aged >18 yrs, admitted to the ED with blood pressure values ≥180 mmHg (SBP) and/or ≥120 mmHg (DBP) were collected and analysed (24% of patients were classified as “hypertensive emergency” and 76% as “hypertensive urgency”). Data in 1218 patients (556 men and 662 women, mean age 70±13 years) were analysed; the mean duration of follow-up after admission to the ED was 19.5±7 months years.
Results
During the follow-up cardiovascular events occurred in 148 patients (69 cardiac events, 43 cerebrovascular events). In 272 pts (22%) a new episode of acute BP rise was recorded. A total of 87 deaths was recorded during follow-up (in 28 patients for cardiovascular causes). All cause and CV mortality were greater in patients with a previous hypertensive emergency (14.7 vs 4.7%, chi-square p=0.0001 and 5.8 vs 1.2% chisquare p<0.0001 for all-cause and for CV mortality, respectively). The incidence of non fatal cardiovascular events was 10,11 and 2,11 per 100 patient-years in patients with hypertensive emergency and urgency, respectively and similar results were obtained when we considered separately the occurrence of cerebrovascular events.
Conclusions
Admission to the ED for hypertensive emergencies identifies hypertensive patients at increased risk for fatal and non fatal cardiovascular events. Our results underline the need for an accurate follow-up in patients with hypertensive emergencies and urgencies.

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

Abstract
The sex-specific effect of skeletal muscle mass (SMM) index (SMI) on 4-year first fatal/non-fatal cardiovascular disease (CVD) event in free-of-disease individuals was examined. In 2009, n = 1411 inhabitants (mean age = 64(12)) from Ikaria were selected. Follow-up was performed in 2013. SMI was created to reflect SMM through appendicular skeletal muscle mass (indirectly calculated through formulas) divided by body mass index (BMI). Fifteen and six tenths percent of participants exhibited CVD (19.8% in men/12% in women, p = 0.002). Significant U-shape trends were observed in participants >65 years old and women irrespective to age confirmed through multi-adjusted Cox regression analysis; in age >65 years, Hazard Ratio (HR)(2nd vs. 1st SMI tertile) = 0.80, 95% Confidence Interval (95%CI) (0.45, 0.96) and in women HR(2nd vs. 1st SMI tertile) = 0.71, 95% CI (0.33, 0.95), while, as for the 3rd SMI tertile, no significant trends were observed. Mediation analysis revealed that mediators of the aforementioned associations in men were the arterial distensibility and total testosterone, while, in women, inflammation, insulin resistance, and arterial distensibility. High SMM accompanied by obesity may not guarantee lower CVD risk. Specific cardiometabolic factors seem to explain this need for balance between lean and fat mass.

Abstract
BACKGROUND AND AIMS Myocardial infarction complicating acute ischemic stroke (IS) is associated with high mortality, but evidence guiding the acute management is scarce. In particular, data on the risk of intracerebral hemorrhage (ICH) due to early cardiac catheterization including the peri-procedural application of antithrombotic drugs in patients with acute ischemic stroke are limited. Here, we aimed to evaluate the incidence and patient characteristics of ICH after cardiac catheterization in acute stroke patients to help to govern the risk of intracranial bleeding versus the benefits of myocardial reperfusion via cardiac catheterization. METHODS We screened a consecutive cohort of n = 126 patients with acute ischemic stroke (IS) who underwent cardiac catheterization during the same hospital stay at a large German neurovascular center (LMU Munich). Eventually, we identified n = 42 patients with cardiac catheterization after acute stroke. N = 22/42 patients did not receive neuroimaging post cardiac catheterization and were discharged without any new neurological deficits, n = 20/42 had neuroimaging after cardiac catheterization and were included for final analysis. RESULTS Cardiac catheterization was performed within a median of 3,6 days after ischemic stroke (No-ICH 7,3 days (IQR, 3,8-16,2) vs. ICH 1,1 days (IQR, 0,8-74,6), p = 0,40), One patient showed new neurological deficits after cardiac procedures (n = 1/42, 2,4 %). New or progressive ICH was ultimately found in 15 % (3/20) of cases. They were classified as HT1, PH1 and PH2 according to ECASS II criteria, respectively. With regards to the coronary catheterization, 85 % of all patients undergoing catheterization ultimately received percutaneous cardiac intervention. ICH was not significantly associated with any of the independent variables. Intrahospital death due to either ischemic stroke, ICH or cardiovascular events did not occur. CONCLUSION The incidence of ICH in ischemic stroke followed by early cardiac catheterization and application of antithrombotic drugs was comparable to studies reporting on the incidence of ICH in ischemic stroke patients without catheterization. This study's results strengthen the hypothesis that in presence of both, acute myocardial infarction and acute ischemic stroke, the general risk for ICH is not prohibitive of cardiac catheterization.

Renal Functional Reserve Is Related to the Nondipping Phenotype and to the Exercise Heart Rate Response in Patients with Essential Hypertension and Preserved Renal Function. Kidney Blood Press Res 2020; 45:737-747.

Abstract
BACKGROUND Renal functional reserve (RFR), defined as the difference between stress and resting glomerular filtration rate (GFR), may constitute a diagnostic tool to identify patients at higher risk of developing acute kidney injury or chronic kidney disease. Blunted RFR has been demonstrated in early stages of hypertension and has been attributed to impaired vascular reactivity due to an overactive sympathetic nervous system (SNS). OBJECTIVE The purpose of this study was to investigate whether RFR correlates with other phenotypes expressing overactivity of the SNS in patients with essential hypertension and preserved renal function. METHODS Thirty-six patients with untreated essential hypertension and a GFR >60 mL/min/1.73 m2 were enrolled. The following parameters were measured: RFR, 24-h ambulatory blood pressure (BP) profile, a treadmill stress test, and an echocardiographic examination. Urine and venous samples were obtained at specific time points for the determination of clinical parameters, and both resting and stress GFR were calculated by using endogenous creatinine clearance for the measurement of RFR after an acute oral protein load (1 g/kg). RESULTS Twenty-one patients had a RFR <30 mL/min/1.73 m2 and 15 had a RFR above this cutoff. A nondipping pattern of 24-h BP was significantly more frequent in patients with low RFR (57.1 vs. 25.0%, p < 0.05 for systolic BP and 52.3 vs. 10.0%, p < 0.02 for diastolic BP). Moreover, patients with lower RFR values showed a blunted heart rate (HR) response to exercise during treadmill test (r = 0.439, p < 0.05). None of the echocardiographic parameters differed between the two groups of patients. CONCLUSIONS In hypertensive patients with preserved GFR, reduced RFR is related to nondipping BP phenotype as well as to attenuated exercise HR response. Overactivity of the SNS may be a common pathway. Since loss of RFR may represent a risk factor for acute or chronic kidney injury, hypertensive patients with blunted RFR might need a more careful renal follow-up.

Abstract
BACKGROUND Hypertension (HT) is an important risk factor for cardiovascular disease and might precipitate pathology of the aortic valve. OBJECTIVE To investigate the association of HT with aortic dysfunction (including both aortic regurgitation and stenosis) and the impact of antihypertensive treatment on the natural course of underlying aortic disease. METHODS We performed a systematic review of the literature for all relevant articles assessing the correlation between HT and phenotype of aortic disease. RESULTS Co-existence of HT with aortic stenosis and aortic regurgitation is highly prevalent in hypertensive patients and predicts a worse prognosis. Certain antihypertensive agents may improve haemodynamic parameters (aortic jet velocity, aortic regurgitation volume) and remodeling of the left ventricle, but there is no strong evidence of benefit regarding clinical outcomes. Renin-angiotensin system inhibitors, among other vasodilators, are well-tolerated in aortic stenosis. CONCLUSION Several lines of evidence support a detrimental association between HT and aortic valve disease. Therefore, HT should be promptly treated in aortic valvulopathy. Despite conventional wisdom, specific vasodilators can be used with caution in aortic stenosis.

Abstract
Objectives: Due to the COVID-19 pandemic, medical curricula face major challenges. This also applies to mentoring programs, where face-to-face meetings are considered essential. Methods: The LMU Munich medical faculty mentoring program (MeCuM-Mentor) adapted to counteract the unforeseen pause of conventional course formats and associated uncertainty of many students. We here present an approach to transform the established large scale or group mentoring events of our program into online formats. Three projects are presented as examples: 1. HowTo Klink (HK), mainly informative in nature and with peer-mentoring character, 2. FacharztDuell (FAD) and 3. "Auf ein Gespräch mit... (AEGM)", both with a focus on career counseling. Results: Initial evaluations show a similarly high participation rate and a high level of satisfaction among the participating students. Students' evaluation of whether the projects presented should take place in presence or in online format has so far shown no clear trend. Conclusion: Prospective studies are necessary to investigate the effectiveness of these online formats and analyse differences in participant behaviour. The extent to which online mentoring can replace classic mentoring functions has to be discussed anew.
