Introduction: Knowledge derived from gender specific research is more and more integrated into the medical education. In Germany this process is developing with a certain delay compared to other Anglo-Saxon or Scandinavian countries. Our survey examines for the first time to what extend gender specific aspects have been integrated into the medical education at the Charite Universitaetsmedizin Berlin. Material and Methods: Topics like gender specific learning objectives and their implementation in the own field were evaluated by means of a standardized questionnaire, differentiated for professors, medical teachers and course coordinators as well as for sex in qualitative and quantitative categories. Results: 30 different fields of medicine took part in this study and revealed a number of important topics with gender specific differences. These contents are integrated into the medical education with relatively simple methods by 70% of the participating professors and medical teachers. In general there is only little interest in spending time for further qualification or the development of a curriculum for the field of gender medicine. Female participants of this study were significantly more interested in gender medicine aspects (p=0,017 development of the medical curriculum). Conclusion: This study underlines the need for official learning objectives containing gender differences during the medical education at the Charite Berlin. A great number of the teaching staff reveals a positive attitude towards these contents and integrates a lot of them. These efforts should be supported by more gender specific teaching material and personal investment into the curricular development. Zielsetzung: Die Erkenntnisse der Geschlechterforschung finden zunehmend Eingang in die medizinische Ausbildung von ÄrztInnen. Dabei steht Deutschland verglichen mit vielen englischsprachigen und nordeuropäischen Ländern noch am Anfang einer Entwicklung. Die vorgelegte Bestandsaufnahme untersucht, welchen Stellenwert geschlechterspezifische Fragestellungen in der Lehre an der Charité Universitätsmedizin Berlin haben. Methodik: Mit Hilfe eines standardisierten Fragebogens wurden verschiedene Themenbereiche wie geschlechtsspezifische Lernziele und die Umsetzung im eigenen Fach quantitativ und qualitativ für ProfessorInnen, DozentInnen und LehrkoordinatorInnen sowie nach Geschlecht erfasst. Ergebnisse: 30 verschiedene Fächer haben an der Bestandsaufnahme teilgenommen und dabei eine Reihe von Themenkomplexen mit geschlechterspezifischen Unterschieden zusammengetragen. Bisher werden solche Themen nur mit relativ einfachen Mitteln in der Lehre durch etwa 70% der angeschriebenen ProfessorInnen und DozentInnen umgesetzt. Insgesamt besteht aber wenig Interesse der Lehrenden an zusätzlichem Zeitaufwand für Qualifizierung oder Curriculumsentwicklung in diesem Bereich. Die weiblichen Teilnehmenden standen dem Thema 'Geschlechterunterschiede in der Medizin' signifikant offener gegenüber (p=0,017 Interesse an Curriculumsentwicklung). Schlussfolgerung: Es gibt einen Bedarf an formulierten Lernzielen für Themenkomplexe mit Geschlechteraspekt im Curriculum des Medizinstudiums an der Charité Berlin. Eine Vielzahl von Lehrenden steht diesen Themenkomplexen offen gegenüber, unterrichtet solche Inhalte bereits und sollte in der Curriculumsentwicklung sowie mit Material bei der Umsetzung im Rahmen ihrer Lehrtätigkeiten unterstützt werden.

Ziel der Studie war es, den Einfluss des Geschlechts auf die Klinik, die medikamentöse Therapie und den Gebrauch von Interventionen bei Patienten mit terminaler dilatativer Kardiomyopathie (DCM) nach Vorstellung zur Herztransplantation zu untersuchen. Es wurden 702 konsekutive DCM-Patienten (110 Frauen, 592 Männer) rekrutiert, die sich am Deutschen Herzzentrum Berlin zur Herztransplatation vorstellten und während eines Zeitraumes von im Mittel 4,3 Jahren beobachtet wurden. Die Diagnose DCM wurde durch Herzkatheter bestätigt. Etwa 300 Variablen zu Basisparametern, medikamentöser Therapie, Interventionen und Outcome wurden pro Patient analysiert. Der kombinierte Endpunkt wurde als das Auftreten eines von drei Ereignissen definiert: Tod auf der Warteliste, Herztransplantation oder Implantation eines Assist-Device. Die Ereignisanalyse wurde mittels multivariater Regression und Kaplan-Meier- Statistik durchgeführt. Bei Erstvorstellung zeigten Frauen und Männer keine Unterschiede in Alter, LVEF und LVEDD (% der Norm, für Alter und BSA korrigiert), aber bei Symptomatik, RVEF, linksatrialem Durchmesser, Vorhofflimmern und Beta1-Autoantikörpern. Frauen wurden signifikant früher transplantiert als Männer (112,3 +/- 117,5 vs. 340,7 +/- 332,1 Tage auf der Warteliste; p = 0,0001). Stärkste unabhängige Prädiktoren für Ereignisse bei beiden Geschlechtern waren korrigierter LVEDD und RVEF. Bei Frauen erhöhte Vorhofflimmern das Ereignisrisiko 3fach (2,905; CI: 1,406 - 6,001), wohingegen das Outcome bei Männern durch Vorhofflimmern nicht beinflusst wurde. Alter bei Erstvorstellung, Belastungsdyspnoe und Immunadsorption waren zusätzliche Prädiktoren bei Männern. Zusammenfassung: Geschlechterunterschiede bei klinischen Basisparametern können Behandlung und Outcome von DCM-Patienten beeinflussen. Vorhofflimmern ist bei männlichen Patienten nicht mit einem schlechteren Outcome assoziiert, bewirkt jedoch eine 3fache Erhöhung des Ereignisrisikos bei weiblichen Patienten., The goal of this study was to determine the influence of gender on clinical parameters, on medical treatment and use of interventions in patients with end-stage dilated cardiomyopathy (DCM) presenting for heart transplantation. We enrolled 702 consecutive patients (592 men and 110 women) with DCM who presented at the German Heart Institute Berlin for heart transplantation and were followed for an average time of 4.3 years. Diagnosis of DCM was confirmed by cardiac catheterization. About 300 variables of baseline characteristics, medical treatment, interventions, and outcome per patient were analysed. The combined end point was defined as the occurrence of one of three events: death on the waiting list, heart transplantation or cardiac assist device implantation and was analyzed by multivariate regression and Kaplan- Meier- statistics. At presentation women and men did not differ in age, LVEF and LVEDD (% of normal, corrected for age and BSA) but in symptoms, RVEF, left atrial size, atrial fibrillation, and beta-adreno-receptor auto-antibodies. Women were transplanted significantly earlier than men (mean 112.3+/-117.5 vs 340.7+/- 332.1 days on the waiting list; p value 0.0001). Strongest independent predictors for events in both sexes were corrected LVEDD and RVEF. In women, AF increased the risk for events 3fold (2,905; CI: 1.406 - 6.001) whereas in men AF did not predict outcome. Age at first presentation, dyspnoea, and immunoadsorption were additional predictors in men. In patients with DCM, gender differences in baseline characteristics may influence management and outcome. Atrial fibrillation is not associated with a poorer outcome in men but threefold increases the risk in women.

Die ersten identifizierten Krankheitsgene der dilatativen Kardiomyopathie (DCM) kodierten alle für Proteine des Zytoskeletts. Deshalb wurde DCM als Erkrankung des Zytoskeletts bezeichnet. Bei der hypertrophen Kardiomyopathie (HCM) wurden bisher mehr als 250 Mutationen in neun Sarkomerprotein-Genen beschrieben. Deshalb wurde HCM als Erkrankung des Sarkomers bezeichnet. In den letzten Jahren wurde dieses Konzept durch Entdeckung von Mutationen in Sarkomerprotein-Genen bei DCM jedoch in Frage gestellt. Vor diesem Hintergrund haben wir die Sarkomerprotein-Gene beta-MHC und Troponin T bei 46 nicht verwandten DCM-Patienten untersucht. Das systematische Mutationsscreening wurde mit Hilfe von SSCP-Analyse und DNA-Sequenzierung durchgeführt. Im beta-MHC-Gen konnten wir die zwei Missense-Mutationen Ala223Thr und Ser642Leu bei zwei jungen Patienten identifizieren. Beide Mutationen wurden weder bei 136 HCM-Patienten noch bei 88 Kontrollen gefunden. Mit dem Editor for Structural Alignment of Proteins (STRAP) wurden die Mutationen auf die Proteinstruktur des Myosins projiziert. Hier ist erkennbar, dass Ala223Thr in der oberen 50 kDa Domäne und Ser642Leu in der Aktin-Myosin-Bindungsregion liegt. Der Austausch von Alanin zu Threonin könnte die Raumstruktur des Proteins verändern, Thermostabilität verringern und die Proteinfaltung und somit die Proteinmotilität beeinträchtigen. In der Aktin-Myosin-Bindungsregion liegt neben Ser642Leu die bereits bekannte DCM-assoziierte Mutation Ser532Pro. Durch eine Verminderung der Krafterzeugung könnten die beiden Mutationen zu DCM führen. Ferner wurden die zwei stummen Mutationen IVS11+23A>T und Asp376Asp und sechs Polymorphismen identifiziert. Im Troponin T-Gen wurden keine Mutationen, jedoch sechs Polymorphismen beobachtet. Es ergab sich kein Anhaltspunkt auf eine funktionelle Relevanz der stummen Mutationen oder Polymorphismen. Wir konnten also bestätigen, dass Mutationen in Sarkomerprotein-Genen sowohl zu HCM als auch zu DCM führen können. All of the initially identified disease-causing genes in dilated cardiomyopathy (DCM) encoded proteins of the cytoskeleton. Therefore DCM has been termed a disease of the cytoskeleton. In hypertrophic cardiomyopathy (HCM) more than 250 mutations in nine sarcomeric protein genes have been identified so far. Therefore HCM has been termed a disease of the sarcomere. However, in the last few years this concept has been queried by findings of mutations in sarcomeric protein genes in DCM. According to this consideration we screened the sarcomeric protein genes beta-MHC and troponin T in 46 patients with DCM. Systematic mutation screening was done using SSCP analysis and DNA sequencing. In the beta-MHC gene we identified the two missense mutations Ala223Thr and Ser642Leu in two young patients. Both mutations were neither found in 136 HCM patients nor in 88 controls. Using the Editor for Structural Alignment of Proteins (STRAP) the mutations were projected onto the protein structure of myosin. Ala223Thr turned out to be localized in the upper 50 kDa domain and Ser642Leu in the actin-myosin-interface region. The exchange from alanine to threonine might alter the spatial structure of the protein, decrease its thermostability and affect the protein folding and thus the protein motility. Closely to Ser642Leu the DCM-associated mutation Ser532Pro is located in the actin-myosin-interface region. By a decrease in force production both mutations might cause DCM. Furthermore we identified the two silent mutations IVS11+23A>T and Asp376Asp and six polymorphisms. In the troponin T gene no mutations but six polymorphisms were detected. No evidence was found for functional relevance of the silent variants or polymorphisms. Thus, we could confirm that mutations in sarcomeric protein genes can lead to both HCM and DCM.

Herzinsuffizienz mit konsekutivem Herzversagen ist ein zentrales kardiovaskuläres Problem der heutigen Bevölkerung.Ursächlich ist insbesondere eine progrediente Herzhypertrophie. Die Calcium-Calmodulin abhängige Phosphatase Calcineurin (CnR) spielt hierbei in der Pathogenese eine entscheidende Rolle. CnR wird über seine Calciumbindungsstellen an der regulatorischen Untereinheit Calcineurin B (CnB) aktiviert.Um zu untersuchen, inwieweit CnB bei der Hypertrophie verschiedener Ätiologien reguliert wird, wurde in linksventrikulären Myokardbiopsien von Patienten mit Aortenstenose (AS= 14) bzw. aus explantierten Herzen mit Dilatativer Kardiomyopathie (DCM=27) und Koronarer Herzerkrankung (KHK=7) der mRNA-und Proteingehalt von CnB bestimmt und mit der Expression von ANP und BNP korreliert. Als Kontrollgruppe dienten 15 abgelehnte Spenderherzen mit normaler systolischer Funktion und gesunder Morphologie. In den Herzen der Kontroll-, DCM-, und KHK-Gruppen wurde der linksventrikuläre Fibrosegehalt bestimmt. Hierzu wurden eine extern standardisierte Real-Time-PCR-Technik und ein etabliertes Western Blot Verfahren angewandt. Die Ergebnisse werden im Median ± 25%/75%-Perzentile angegeben und mit dem Mann-Whitney-Test bzw. Korrelationsanalysen nach Spearman berechnet. In den Herzen mit DCM zeigte sich eine signifikante Erhöhung der CnB mRNA auf ca. das Dreifache der Kontrollen (293% der Ko, p Heart failure is a central cardiovascular problem for the current population. Cardiac hypertrophy is a central factor. The calcium-Calmodulin dependent phosphatase Calcineurin (CnR) plays a crucial role in the pathogenesis. CnR is activated via its calcium-binding site in the regulatory subunit Calcineurin B (CnB). In order to examine, to what extent CnB is regulated in different aetiologies of hypertrophy, we analysed CnB´s mRNA and protein in left ventricular samples from patients with aortic valve stenosis (AS = 14) and from explanted hearts with dilated (DCM=27) and ischemic (ICM=7) cardiomyopathy and correlated them with the expression of ANP and BNP. As a control, 15 rejected donor hearts with normal systolic function and non-pathologic changed morphology were used. Fibrosis of the left ventricle was determined in three groups: control , DCM and ICM. Therefore, we used an externally standardized real-time PCR and an established Western Blot. Data are given as median ± 25%/75%- percentiles; Mann Whitney test and Spearman´s correlation-analyses were used. CnB mRNA was significantly raised in DCM (293% of control, p

Cardiotrophin-1 ist ein Zytokin der Familie Interleukin-6-Familie, zu der auch IL-11, CNTF, OSM und LIF gehören. Diese Substanzen wirken über die gemeinsame Rezeptoruntereinheit gp130. CT-1 induziert die Hypertrophie von Kardiomyozyten und inhibiert die Apoptose kardialer und Zellen. In verschiedenen Tiermodellen der Herzinsuffizienz konnte eine gesteigerte myokardiale CT-1 Expression beobachtet werden. Kardiomyopathien sind wiederum kardiale Erkrankungen, die mit einer Hypertrophie und Apoptose einhergehen und zu einer Herzinsuffizienz führen können. Man geht davon aus, dass 25-50 Prozent der familiär sind. Hierbei handelt es sich um eine monogenetische Erkrankung, die überwiegend autosomal-dominant vererbt werden. Daneben konnten aber auch modifizierende Polymorphismen in neurohumoralen Faktoren identifiziert werden. Basierend auf diesen Ergebnissen war das Ziel dieser Arbeit die Analyse der möglichen Beteiligung genetischer Varianten der kodierenden sowie der regulatorischen Region an der Pathogenese der Hypertrophen bzw. Dilatativen Kardiomyopathie. Zusätzlich sollte die mRNA-Expression von CT-1 in Myokardbiopsien von Patienten mit Herzinsuffizienz quantifiziert werden. Hierfür musste zunächst die Sequenzen der 5´-flankierenden Region identifiziert und bezüglich ihrer regulatorischen Eigenschaften analysiert werden. Es konnten 1,1 kb der 5´-flankierenden Region sequenziert werden. Die anschließende Luciferase-Reportergen-Analyse wies regulatorische Aktivitäten für den gesamten Bereich nach. Diese Region enthält zahlreiche cis-aktive DANN-Sequenzen aber keine TATA-Box. Für die Mutationssuche wurden 64 Patienten mit DCM, 53 Patienten mit HCM sowie 100 Kontrollpersonen mittels PCR-SSCP-Analyse untersucht. Es konnte eine kodierende Variante A92T bei jeweils einem DCM- bzw. HCM-Patienten identifiziert werden. Diese Substitution liegt in einem Bereich, der zwischen verschiedenen Spezies (Ratte, Maus, Mensch) konserviert ist. Diese Mutation könnte eine Veränderung der Sekundärstruktur bewirken und liegt in einem möglichen funktionellen Bereich. Die Promotorregion wies eine Basenpaarsubstitution bei -130 (G/T) sowie eine Deletion der Basen CTTT zwischen -992 und -995 auf. Der Polymorphismus an Position -130 fand sich tendenziell häufiger bei Patienten mit Dilatativer Kardiomyopathie. Die CTTT-Deletion konnte nur bei einer Patientin mit HCM nachgewiesen werden. Für die Quantifizierung der CT-1 mRNA wurden rechtsventrikuläre Endomyokardbiopsien von 6 Patienten mit eingeschränkter LVEF (CHI), 5 Patienten nach Herztransplantation (TX) sowie 3 Kontrollpatienten (KO) eingesetzt. Es konnte ein relativer Anstieg der CT-1 Expression um 82% bei den Patienten mit eingeschränkter LVEF festgestellt werden. Interessanterweise besteht eine enge Korrelation zur Schwere der eingeschränkten Herzfunktion sowie zur Zunahme der Hypertrophie. Cardiotrophin-1 is a cytokine, which belongs to the interleukin-6 family, which includes IL-11, CNTF, OSM and LIF. These factors act via the receptor subunit gp130. CT-1 induces the hypertrophy of cardiomyocytes and inhibits the apoptosis of cardiac cells. Studies in animal models of congestive heart failure showed an enhanced expression of CT-1 in the myocardium. Cardiomyopathies are cardiac diesorders, which are charakterized by hypertrophy and apoptosis and which can terminate with congestive heart failure. About 25-50 percent of all cases are familial. It is a monogenetic mendelian disorder with an autosomal-dominant inheritance in most cases. Beside this, modifying polymorphisms in neurohunoral factors could be identified. Based on these facts, the aim of this study was to identify genetic variants within the coding and regulatory region of the CT-1 gene, which could influence the pathogenesis of hypertrophic or dilated cardiomyopathy. Additionally, the mRNA-expression of CT-1 in myocardial biopsies of heart failure patients should be quantified. First, it was necessary to sequence the 5´-untranslated region and to analyse its regulatory function. We could sequence 1.1 kb of the 5´-UTR. The luciferase reportergene assay showed a significant promoter activity for the whole region. The region contains various cis-active DNA sequences but no TATA-box.The TRANSFAC-analysis identified different binding sites for transcription factors but no TATA-box. The genetic material of 64 DCM and 53 HCM patients and 100 controls was screened for mutaions by using a PCR-based SSCP-analysis. A coding variant A92T could be identified for a patient with DCM and for an HCM patient. This mutation lies within a region which is conserved between different species (rat, mouse, human). This variant could disturb the secondary structure and lies in a probable functional region. Within the promoter we could identify a basepair substitution at position -130 (G/T) and a 4-basepair deletion between -992 and -995 (CTTTdel). The polymorphism at -130 showed a tendency for a higher occurrence in DCM patients. One HCM patient was heterozygous for the CTTT-deletion. To quantify the CT-1 mRNA we used endomyocardial biopsies of 6 patients with reduced LVEF (CHI), 5 patients after heart transplantation (TX) and 3 controls (KO). We performed a semiquantitative analysis by using HPLC and an external standard (PDH mRNA). We found an increased expression of CT-1 by 82% for patients with heart failure. Interestingly, we saw a tight correlation with to the reduction in LV function and to the degree of hypertrophy.

Die hypertrophe Kardiomyopathie ist eine autosomal dominant vererbte Herzmuskelerkrankung. Es kommt zu einer asymmetrischen Hypertrophie insbesondere des Herzmuskels. Symptome sind unspezifisch und reichen von Dyspnoe bis hin zu Synkopen. Gelegentlich ist der plötzliche Herztod die erste Manifestation der Erkrankung. Molekulargenetische Untersuchung des Genomes dieser Patienten zeigten, dass diese Patienten Mutationen im Proteinen des Sarkomers aufwiesen. Hierunter fällt das beta-MHC-Gen und alpha-Tropomysin-Gen. Wir untersuchten 45 nicht miteinanderverwandte Patienten auf Mutationen im beta-MHC-Gen und im alpha-Tropomysin-Gen. Folgende molekulargenetische Untersuchungen wurden angewendet: Polymerase-Ketten-Reaktion, Single-Strand-Polymorphismus-Anlyse und Sequenzierung. Bei 6 Patienten (13%) fanden wir eine Mutation im beta-Myosin-Gen. Kein Patient hatte eine Mutation im alpha-Tropomyosin-Gen. In der Literatur wird eine Mutation im beta-MHC-Gen in bis zu 35% und im alpha-Tropomyosin-Gen in bis zu 3% der Fälle angenommen. Unsere Patienten hatten die Mutationen: Exon 13 Arg403Trp und Val411Ile, Exon 19 Arg719Trp, Exon 20 Ile736Thr, Exon 21 Leu796Phe und Exon 23 Cys905Phe. Die Mutationen Arg403Trp und Arg719Trp waren vorher bereits bekannt. Die Mutationen, Ile736Thr, Val411Ile, Leu796Phe und Cys905Phe wurden in der Form von uns erstmals ermittelt. Offensichtlich besitzen unsere Patienten überdurchschnittlich häufiger Mutationen in anderen Genen, die in dieser Studie nicht untersucht wurden. Der Phänotyp der Krankheit der HCM war bei unserem Patientenkollektiv sehr heterogen, und es ließen sich keine signifikanten Unterscheidungen eststellen. So haben wir uns darauf beschränkt, bei den 6 Patienten mit Mutationen nur nach den von Burn et al. (1997) aufgestellten Risikofaktoren zu suchen, die einen plötzlichen Herztod herbeiführen können, und haben sie danach in Patienten mit einem höheren oder niedrigeren Risiko eingestuft. Kriterien für ein erhöhtes Risiko, einen plötzlichen Herztod zu erleiden, wurden von Patienten mit den Mutationen: Exon 13 Arg403Trp, Exon 13 Val411Ile, Exon 19 Arg719Trp, Exon 20 Ile736Thr und Exon 21 Leu796Phe erfüllt. Mutationen an diesen Positionen sind auch in der Literatur mit einem erhöhten Risiko für einen plötzlichen Herztod assoziiert worden. Der Patient mit der Mutation im Exon 23 Cys905Phe wies wenige Risikofaktoren auf und unterscheidet sich somit nicht von den in der Literatur beschriebenen Patienten. Wir konnten dies mit unseren Ergebnissen bestätigen., Hypertrophic Cardiomyopathy is disease of the cardiac muscle which results in an asymmetric hypertrophy especially of the interventricularseptum of the heart. It is transmitted in an autosomal dominant way. The symptoms are unspecific reaching from dyspnoe to syncopes. Sometimes the sudden death is the first manifestation of the disease. Molekular genetic researches showed that in the patients genes Mutations in proteins of the sarkomer were detectable. Two of them are alpha-Tropomyosin and beta-Myosin Heavy Chain. We examined 45 unrelated Patient of the existence of Mutations in alpha-Tropomyosin and beta-Myosin Heavy Chain. We used following Examinations: PCR, SSCP, Sequencing. A mutation in the beta-Myosin Heavy Chain were found in 6 Patients (13%), non in alpha-Tropomyosin. Generally mutations are expected in 35% in beta-Myosin Heavy Chain and 3% in alpha-Tropomyosin. Our patients seem to have mutations in genes we did not examine in this study. We detected Mutations in: Exon 13 Arg403Trp and Val411Ile, Exon 19 Arg719Trp, Exon 20 Ile736Thr, Exon 21 Leu796Phe und Exon 23 Cys905Phe. Mutation Arg 403Trp and Arg719Trp have been known in this form before, the others were new. As the phenotypes of our patients were heterogenous and not significantly to be distinguished we looked for risk factors for sudden death as described by Burn et al. 1997 within our group of patients with mutations. Five Persons showed risk factors as discribed: Exon 13 Arg403Trp and Val411Ile, Exon 19 Arg719Trp, Exon 20 Ile736Thr, Exon 21 Leu796Phe. The person with the mutation Exon 23 Cys905Phe showed no risk factors for sudden death. Our results correlate with those of earlier studies. The patient with the mutation Exon 23 Cys905Phe was classified as a low risk patient while the other mutations correlate with a further high risk.

- Abstract
Women with known cardiovascular diseases (CVD) and a desire to have children should receive a timely comprehensive counselling before becoming pregnant. This is critical as the foundation for an informed decision-making process of the mother and her family. Furthermore, a detailed interdisciplinary management plan should be developed and discussed with the patient. The modified World Health Organization (mWHO) classification should be applied for maternal cardiovascular risk stratification. Although the prevalence of aortic pathologies is infrequent, they are often life-threatening conditions. Following the recent advances in terms of surgical management and anticoagulation, the adequate management of valvular heart disease is particularly challenging. Cardiomyopathies during pregnancy are associated with high maternal mortality and severe cardiovascular complications, such as progressive heart failure and thromboembolic events; however, novel treatment options have recently become available., (© 2021.

- Abstract
Background: Sex/gender differences pose a challenge in the care of patients with chronic coronary artery disease (CAD) especially in the resident sector. The aim of the AURORA trial was to obtain a nationwide overview on how resident cardiologists deal with sex/gender-specific aspects of symptomatic chronic CAD in their medical routine care and in the interplay with general practitioners, as well as derive insights out of it for general practice., Method: Between October 2018 and April 2019 a survey among German cardiologists (n = 360) in the outpatient sector was performed using a structured questionnaire. Items focused on the cardiologists' personal assessment of sex/gender aspects in the diagnosis and treatment and consequences for the overall medical care of patients with chronic CAD., Results: The range of symptoms of chronic CAD in male and female patients was differently assessed by the participating male or female cardiologists. General practitioners referred men at an earlier stage than women to a cardiologist for further testing. In male and female patients with non-obstructive CAD cardiovascular risk was largely assessed as comparable to patients with obstructive CAD. In terms of medical care, it was shown that therapeutic decisions made by cardiologists were generally considered and continued by the general practitioners., Conclusions: Results from previous trials on sex/gender differences in ischemic heart disease have made their way into medical care. However, they also show potential for optimization in diagnosis, treatment and collaboration between resident cardiologists and general practitioners. Overall the results indicate that sex/gender differences in chronic CAD gain more medical attention. However, there is a current lack of concise sex-specific guidelines for prevention, diagnosis and treatment.

- Abstract
Many drugs have act differently in women and men. Biological differences between women and men lead to sex differences in pharmacokinetics, i.e., in drug absorption, distribution in tissues, metabolism by liver enzymes, and excretion via the kidney and intestine. In addition there are sex differences in pharmacodynamics, leading to a different efficacy of drugs in women and men. The biological differences between women and men may be caused by sex-specific gene expression, by sex-specific epigenetic modifications, and finally by the effect of sex hormones. In addition, gender plays a role in drug efficacy as a sociocultural dimension that may lead to differences between women and men. Frequently drugs are only tested on animals of one sex and thereby optimized for one sex. This is based on the notion that sex differences are not important for clinical drug effects. Furthermore, to date, sex and gender differences have been underestimated in clinical studies, and phase III studies were not prospectively designed to assess sex differences in drug effects. In addition, women and men use drugs differently with respect to compliance, adherence, and self-medication with over-the-counter drugs. Further, it is known that male and female physicians treat women and men as patients differently. In conclusion, drug therapy is not yet optimized for both genders. However, there is increasing awareness that differences between women and men should be respected in order to provide optimal drugs in optimal doses for both genders.

- Abstract
Women and men differ in drug needs and drug metabolism. Usually women are smaller and lighter and have a higher body fat percentage and lower kidney function. Primary drug-metabolizing enzymes in the intestinal wall and liver, which are part of the cytochrome P450 family, have different activities in men and women. Their substrates (beta-blockers, blockers of calcium channels such as nifedipine and verapamil, cyclosporine, and many others) are metabolized differently. Sex differences were observed after administration of digitalis, which is often overdosed in women. Furthermore, beta-blockers are found at higher plasma levels in women and ACE inhibitors cause more side effects in women than in men. In women, acetylsalicylic acid provides effective primary prophylaxis against stroke but not myocardial infarction. In men, these drugs have opposite effects. Anticoagulants and thrombolytics often lead to bleeding complications in women, QT prolonging drugs produce more frequently arrhythmia. It is therefore very important to control drugs following approval and to look out for these differences between men and women.

- Abstract
In cardiovascular diseases e.g. heart failure and coronary artery disease gender differences are evident in etiology, pathophysiology, clinical presentation, prognosis and response to treatment. Diabetes and hypertension are the major risk factors in women. Mechanisms leading to apparent diabetes or its clinical pre-stage are different in women and men and according to this result in different therapeutic implications. Diastolic heart failure is more frequent in women and effects and side effects of important groups of active pharmaceutical substances are, at least to some extent, different. Atrial fibrillation and ventricular arrhythmia differ in frequency of occurrence; drug induced tachycardia with QT interval prolongation is particularly frequent in women. Underlying pathomechanisms responsible for gender differences in pharmacotherapy are on the one hand differences in pharmacokinetic mechanisms. Particularly drugs which are metabolised via cytochrome P 450 CYP 3A pathway show different kinetics in women and men. In addition, important differences are evident in pharmocodynamics caused by effects of sex steroid hormones or products of X-chromosomal genes. The evidence of estrogen and testosterone receptors in cardiomyocytes and the vascular system, interaction of sex steroid hormones with cellular pathways and the role of X-chromosomal genes are the focus of basic research. Interactions of sex steroid hormone receptors with other nuclear receptors e.g. PPARs ("peroxisome proliferator-activated receptors") are another important underlying mechanism. The knowledge of different pharmacokinetic mechanisms has to be taken into consideration in pharmacotherapy of cardiovascular diseases, for example by adjustment of drug dosages in women, necessary in different groups of pharmaceutical substances or in the long run, gender differences in effects and side effects of drugs. In drug development both aspects have to be considered. There is more than one good reason to intensify basic and clinical research and research on health care on gender differences in cardiovascular diseases.

- Abstract
Large differences exist between women and men in the syndrome of heart failure (HF). In contrast to men, hypertension and diabetes represent the major risk factors for development of HF in women and hypertension is also the major cause of left ventricular hypertrophy and stroke. Left ventricular hypertrophy in women increases the risk for mortality to a higher degree than it does in men. The clinical course of HF is generally more benign and more frequently characterized by HF with preserved systolic function. Estrogen receptors are present in the human heart. Based on data from rodent models, they are believed to modulate hypertrophy and the progression of HF. Some of the signaling pathways have been described and involve phosphorylation of intracellular kinases and production of nitric oxide. Interestingly, estrogen receptors are upregulated in human hypertrophy and HF. The clinical course of HF in women is characterized by the more frequent occurrence of diastolic HF. Myocardial remodeling with age and, as a consequence, of mechanical load is different in both genders. Adherence to guidelines in the diagnosis and treatment of HF is less strict in women than in men, leading to undertreatment with inhibitors of the renin-angiotensin system. Women are generally underrepresented in clinical trials in HF and gender-specific analyses have been neglected in most older large survival trials. In some of the large survival studies angiotensin-converting enzyme inhibitors or beta-receptor blockers did not reach significant endpoints in women. However, meta-analyses show overall positive effects for these groups of substances. Angiotensin receptor blockers were effective in large studies including high percentages of women.

- Abstract
So far, two angiotensin receptor subtypes, called AT1 and AT2, have been described in an animal model and in human. AT1 mediates almost all known effects of angiotensin II and its gene sequence and regulation is well studied. In contrast, only few data on function and regulation of AT2 are available. The complete mRNA sequence of AT2 has only recently been cloned and sequenced. The angiotensin receptors' receptor density and subtype distribution is organ specific. In the rat, lowest densities are found in the myocardium, followed by kidney, liver, adrenal medulla and cortex. The percentage of AT1 in the different organs amounts to 80, 85, 90, 57 and 10%. Angiotensin receptor subtypes have also been quantitated in human myocardium. There, the relatively unknown subtype AT2 dominates (67%). Myocardial receptor density is low, amounting to about 11 fmol/mg protein corresponding to 1/20-1/50 of the density of beta-adrenergic receptors. Angiotensin receptors in the human heart are present on cardiac fibroblasts and induce proliferation of these cells. Blockade of the renin angiotensin system by ACEI and AT1 antagonists in the rat downregulates angiotensin receptors in liver, kidney and adrenals to about 50% in an organ- and subtype specific manner, whereas cyclosporin A upregulates receptors twice. In end-stage human heart failure, but not in early stages, angiotensin receptors are downregulated to 1/3 of control values. Regulator mechanisms at transcriptional level have been elucidated by reporter gene assays; PMA, an activator of proteinkinase C, stimulates the transcription of the AT1 gene. The organ- and subtypespecific regulation of angiotensin receptors by pharmacological agents and/or cardiovascular diseases can contribute to the understanding of these drugs and of the pathophysiology of the corresponding diseases.
