Cardiovascular and physiological risk factors in women at midlife and beyond.

Cardiovascular disease (CVD) is the leading cause of death in women. After menopause, sex-specific and gender-specific factors may play an important role in increasing CVD risk, with changes in sex hormones, body fat distribution, lipid and metabolic profile, and structural and functional vascular modifications. Premature and early-onset menopause are detrimental to cardiovascular health due to the early cessation of the protective effect of endogenous estrogen. An independent association of menopause with an increased risk of CVD has been documented in early menopause (<45 years). Sex-related differences are relevant in pharmacokinetics and pharmacodynamics; different enzyme formations, drug compatibility, efficacy, and side effects vary for different sexes. Despite some progress in sex and gender research in CVD, disparities remain. Menopausal hormone therapy (MHT) is available at midlife for symptoms of menopause and may impact CVD risk. Taken early, MHT may reduce CVD morbimortality. However, this is balanced againts the risk of increased thrombosis. This paper reviews physiologic changes that contribute to cardiovascular risk in postmenopausal women and discusses clinical implications. Specifically, it explores the atheroprotective effects of estrogen and menopausal hormone therapy and the associations between menopause with lipid levels, hypertension, body composition, and diabetes for women at midlife and beyond.

Integration of Women's Cardiovascular Health Content Into Healthcare Provider Education: Results of a Rapid Review and National Survey.

Despite its importance, formal education in healthcare training programs on sex- and gender-specific cardiovascular disease (CVD) risk factors, symptoms, treatment, and outcomes is lacking. We completed rapid reviews of the academic and grey literature to describe the current state of women-specific CVD education in medical, nursing, and other healthcare education programs. Second, we analyzed results from a Canada-wide survey of healthcare professional education programs to identify gaps in curricula related to sex- and gender-specific training in CVD. Our academic review yielded only 15 peer-reviewed publications, and our online search only 20 healthcare education programs, that note that they specifically address women, or sex and gender, and CVD in their curricula. Across both searches, the majority of training and education programs were from the USA, varied greatly in length, delivery mode, and content covered, and lacked consistency in evaluation. Of surveys sent to 213 Canadian universities and other entry-to-practice programs, 80 complete responses (37.6%) were received. A total of 47 respondents (59%) reported that their programs included women-specific CVD content. Among those programs without content specific to CVD in women, 69.0% stated that its inclusion would add "quite a bit" or "a great deal" of value to the program. This study highlights the emerging focus on and substantial gaps in women-specific CVD training and education across healthcare education programs. All medical, nursing, and healthcare training programs are implored to incorporate sex- and gender-based CVD content into their regular curricula as part of a consolidated effort to minimize gaps in cardiovascular care.

Malgré la prévalence des maladies cardiovasculaires (CV), les programmes d'enseignement en santé accordent peu d'attention aux facteurs de risque, aux symptômes, aux traitements et aux issues selon le sexe ou le genre. Premièrement, nous avons fait une revue rapide de la littérature universitaire et la littérature grise pour faire état de la formation sur les maladies CV spécifiques aux femmes dans les programmes d'enseignement en médecine, en soins infirmiers et autres domaines de la santé. Deuxièmement, nous avons analysé les résultats d'une enquête menée à l'échelle du Canada sur des programmes de formation professionnelle pour cerner les lacunes dans les programmes au chapitre de la formation sur les maladies CV en fonction du sexe et du genre. Notre analyse de la littérature universitaire a permis de relever seulement 15 publications révisées par des pairs à ce sujet, et notre recherche en ligne a mis au jour seulement 20 programmes d'enseignement qui comportent un volet portant spécifiquement sur les femmes, ou bien le sexe et le genre, et les maladies CV. Ces deux enquêtes ont révélé que la majorité des programmes de formation et d'enseignement étaient aux États-Unis et qu'ils présentaient une grande diversité sur le plan de la durée, du mode d'enseignement et du contenu abordé. De plus, les méthodes d'évaluation n'étaient pas uniformes. Parmi les sondages envoyés à 213 universités et programmes d'admission à la pratique au Canada, 80 réponses complètes (37,6 %) ont été reçues. Quarante-sept des établissements qui ont répondu (59 %) ont signalé que leurs programmes comprenaient du contenu portant sur les maladies CV spécifiques aux femmes. Parmi les établissements dont les programmes ne comportaient aucun contenu spécifique aux femmes, 69,0 % ont indiqué qu'une telle inclusion ajouterait « beaucoup ¼ ou « énormément ¼ de valeur au programme. Cette étude met en lumière l'attention nouvelle accordée à la formation et à l'enseignement sur les maladies CV spécifiques aux femmes ainsi que les lacunes substantielles observées à cet égard dans les programmes d'enseignement en santé. Les programmes de formation en médecine, en soins infirmiers et en santé sont vivement invités à intégrer du contenu spécifique au sexe et au genre pour ce qui est des maladies CV dans un effort concerté visant à réduire les lacunes dans les soins cardiovasculaires.

Imprecision of high-sensitivity cardiac troponin assays at the female 99th-percentile.

BACKGROUND: An analytical benchmark for high-sensitivity cardiac troponin (hs-cTn) assays is to achieve a coefficient of variation (CV) of ≤ 10.0 % at the 99th percentile upper reference limit (URL) used for the diagnosis of myocardial infarction. Few prospective multicenter studies have evaluated assay imprecision and none have determined precision at the female URL which is lower than the male URL for all cardiac troponin assays. METHODS: Human serum and plasma matrix samples were constructed to yield hs-cTn concentrations near the female URLs for the Abbott, Beckman, Roche, and Siemens hs-cTn assays. These materials were sent (on dry ice) to 35 Canadian hospital laboratories (n = 64 instruments evaluated) participating in a larger clinical trial, with instructions for storage, handling, and monthly testing over one year. The mean concentration, standard deviation, and CV for each instrument type and an overall pooled CV for each manufacturer were calculated. RESULTS: The CVs for all individual instruments and overall were ≤ 10.0 % for two manufacturers (Abbott CVpooled = 6.3 % and Beckman CVpooled = 7.0 %). One of four Siemens Atellica instruments yielded a CV > 10.0 % (CVpooled = 7.7 %), whereas 15 of 41 Roche instruments yielded CVs > 10.0 % at the female URL of 9 ng/L used worldwide (6 cobas e411, 1 cobas e601, 4 cobas e602, and 4 cobas e801) (CVpooled = 11.7 %). Four Roche instruments also yielded CVs > 10.0 % near the female URL of 14 ng/L used in the United States (CVpooled = 8.5 %). CONCLUSIONS: The number of instruments achieving a CV ≤ 10.0 % at the female 99th-percentile URL varies by manufacturer and by instrument. Monitoring assay precision at the female URL is necessary for some assays to ensure optimal use of this threshold in clinical practice.

Approach to risk stratification of atherosclerotic cardiovascular disease: Use of biomarkers and imaging in a Canadian context.

OBJECTIVE: To outline the 2021 Canadian Cardiovascular Society (CCS) dyslipidemia guidelines and to present the current approaches to cardiovascular risk stratification, including the incorporation of biomarkers and imaging tests. SOURCES OF INFORMATION: Current guidelines were reviewed and an Ovid MEDLINE literature search was performed. MAIN MESSAGE: Cardiovascular disease (CVD) is the leading cause of global mortality, with ischemic heart disease contributing to nearly half of these deaths. Risk stratification is undertaken to identify patients who would benefit from primary prevention for atherosclerotic CVD (ASCVD), but commonly used methods for risk stratification are imperfect. The CCS guidelines endorse that the presence of risk modifiers (family history of premature ASCVD, high-sensitivity C-reactive protein level ≥2.0 mg/L, lipoprotein[a] level ≥500 mg/L [≥50 mg/dL], or coronary artery calcium >0) supports the use of statin therapy in those at intermediate risk (Framingham risk score 10% to 19.9%) who do not otherwise meet the recommendations for statin use. The CCS guidelines recommend statin therapy in patients at intermediate risk when cholesterol levels are elevated (low-density lipoprotein cholesterol level ≥3.5 mmol/L, non-high-density lipoprotein cholesterol level ≥4.2 mmol/L, or apolipoprotein B level ≥1.05 g/L). In addition, statin therapy should be considered for patients at low risk (Framingham risk score 5% to 9.9%) with elevated cholesterol levels, especially if risk modifiers are present. When cholesterol levels are not elevated, evidence still favours the use of statins in intermediate-risk patients when risk modifiers are present and in men 50 years and older and women 60 years and older with 1 additional risk factor. CONCLUSION: Biomarkers and imaging tests have the potential to improve ASCVD risk stratification by reclassifying any patient whose risk has been inaccurately estimated by traditional methods. Recently published guidelines by the CCS suggest the use of biomarkers and imaging in certain patient groups.

Approche de la stratification du risque de maladies cardiovasculaires athéroscléreuses: Utilisation des biomarqueurs et de l'imagerie en contexte canadien.

OBJECTIF: Donner un aperçu des lignes directrices de la Société canadienne de cardiologie (SCC) de 2021 sur la dyslipidémie et présenter les approches actuelles relatives à la stratification du risque cardiovasculaire, y compris l'intégration de la mesure des biomarqueurs et de l'imagerie. SOURCES DE L'INFORMATION: Les lignes directrices actuelles ont été passées en revue, et une recherche documentaire dans Ovid MEDLINE a été effectuée. MESSAGE PRINCIPAL: Les maladies cardiovasculaires (MCV) sont la principale cause de mortalité dans le monde, et les cardiopathies ischémiques contribuent à près de la moitié de ces décès. Une stratification du risque est entreprise pour identifier les patients susceptibles de bénéficier d'une prévention primaire de la MCV athéroscléreuse (MCVAS), mais les méthodes habituellement utilisées pour la stratification du risque sont imparfaites. Les lignes directrices de la SCC soutiennent que la présence de modificateurs du risque (antécédents familiaux de MCVAS prématurée, dosage de la protéine C réactive hypersensible ≥2,0 mg/L, dosage de la lipoprotéine [a] ≥500 mg/L [≥50 mg/dL] ou score calcique coronarien >0) justifie le recours à une thérapie aux statines chez les personnes à risque moyen (score de risque de Framingham de 10 à 19,9 %) qui ne sont pas autrement visées par les recommandations en faveur de l'utilisation de statines. Les lignes directrices de la SCC recommandent une thérapie aux statines chez les patients à risque modéré, lorsque leurs taux de cholestérol sont élevés (taux de cholestérol à lipoprotéines de basse densité ≥3,5 mmol/L, taux de cholestérol lié aux lipoprotéines autres que celles de haute densité ≥4,2 mmol/L ou taux d'apolipoprotéines B ≥1,05 g/L). De plus, une thérapie aux statines devrait être envisagée pour les patients à faible risque (score de risque de Framingham de 5 à 9,9 %) dont les taux de cholestérol sont élevés, surtout en présence de modificateurs du risque. Lorsque les taux de cholestérol ne sont pas élevés, des données probantes favorisent quand même le recours aux statines chez les patients à risque modéré lorsque des modificateurs du risque sont présents, de même que chez les hommes de 50 ans et plus et chez les femmes de 60 ans et plus ayant 1 facteur de risque additionnel. CONCLUSION: La mesure des biomarqueurs et l'imagerie ont le potentiel d'améliorer la stratification du risque de MCVAS en reclassant les patients dont le risque avait été estimé de manière inexacte par les méthodes traditionnelles. Les lignes directrices récemment publiées par la SCC suggèrent de se servir des biomarqueurs et de l'imagerie chez certains groupes de patients.

Canadian Cardiovascular Society 2022 Guidelines for Peripheral Arterial Disease.

Patients with widespread atherosclerosis such as peripheral artery disease (PAD) have a high risk of cardiovascular and limb symptoms and complications, which affects their quality of life and longevity. Over the past 2 decades there have been substantial advances in diagnostics, pharmacotherapy, and interventions including endovascular and open surgical to aid in the management of PAD patients. To summarize the evidence regarding approaches to diagnosis, risk stratification, medical and intervention treatments for patients with PAD, guided by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework, evidence was synthesized, and assessed for quality, and recommendations provided-categorized as weak or strong for each prespecified research question. Fifty-six recommendations were made, with 27% (15/56) graded as strong recommendations with high-quality evidence, 14% (8/56) were designated as strong recommendations with moderate-quality evidence, and 20% (11/56) were strong recommendations with low quality of evidence. Conversely 39% (22/56) were classified as weak recommendations. For PAD patients, strong recommendations on the basis of high-quality evidence, include smoking cessation interventions, structured exercise programs for claudication, lipid-modifying therapy, antithrombotic therapy with a single antiplatelet agent or dual pathway inhibition with low-dose rivaroxaban and aspirin; treatment of hypertension with an angiotensin converting enzyme or angiotensin receptor blocker; and for those with diabetes, a sodium-glucose cotransporter 2 inhibitor should be considered. Furthermore, autogenous grafts are more effective than prosthetic grafts for surgical bypasses for claudication or chronic limb-threatening ischemia involving the popliteal or distal arteries. Other recommendations indicated that new endovascular techniques and hybrid procedures be considered in patients with favourable anatomy and patient factors, and finally, the evidence for perioperative risk stratification for PAD patients who undergo surgery remains weak.

Permission to prescribe: do cardiologists need permission to prescribe diabetes medications that afford cardiovascular benefit?

PURPOSE OF REVIEW: Antihyperglycemic therapies including sodium glucose contransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1 RA) have been demonstrated to confer significant cardiovascular benefit and reduce future events in patients with type 2 diabetes mellitus (T2DM). However, despite positive data from cardiovascular outcome trials, these therapies remain underutilized in a large proportion of patients who have clinical indications and meet coverage guidelines for their initiation. One of the causes of the observed gap between scientific evidence and clinical cardiology practice is therapeutic hesitancy (otherwise known as therapeutic inertia). The purpose of this review is to discuss the contributors to therapeutic hesitancy in the implementation of these evidence-based therapies and, more importantly, provide pragmatic solutions to address these barriers. RECENT FINDINGS: Recent studies have demonstrated that clinicians may not initiate cardiovascular protective therapies due to a reluctance to overstep perceived interdisciplinary boundaries, concerns about causing harm due to medication side effects, and a sense of unfamiliarity with the optimal choice of therapy amidst a rapidly evolving landscape of T2DM therapies. SUMMARY: Herein, we describe a multifaceted approach aimed at creating a 'permission to prescribe' culture, developing integrated multidisciplinary models of care, enhancing trainees' experiences in cardiovascular disease prevention, and utilizing technology to motivate change. Taken together, these interventions should increase the implementation of evidence-based therapies and improve the quality of life and cardiovascular outcomes of individuals with T2DM.

Incorporating a Women's Cardiovascular Health Curriculum Into Medical Education.

Despite cardiovascular disease (CVD) being the leading cause of death of women globally, research on CVD over the past several decades has focused primarily on men. CVD research has led to progress in diagnosis and treatment, medical education, and public awareness; however, few of these advances have applied specifically to women's cardiovascular health. There is a paucity of sex- and gender-specific educational material regarding CVD in clinical training programs for physicians. The irregularity in integrated curricula across medical schools in Canada may be a factor in persistent disparities in clinical care and outcomes experienced by women, compared with men. In response to this gap, the Training and Education Working Group of the Canadian Women's Heart Health Alliance undertook the planning, development, and dissemination of a Canadian Women's Heart Health Education Course. The development of the course was guided by a 6-step approach for curriculum development for medical education, which included conducting a needs assessment, determining and prioritizing content, setting goals and objectives, selecting educational strategies, implementation, and evaluation.

Bien que les maladies cardiovasculaires (MCV) soient la principale cause de décès chez les femmes dans le monde, la recherche sur les MCV au cours des dernières décennies a été centrée principalement sur les hommes. La recherche sur les MCV a permis de faire des progrès en matière de diagnostic et de traitement, de formation médicale et de sensibilisation du public; toutefois, peu de ces progrès touchaient spécifiquement la santé cardiovasculaire des femmes. Les programmes de formation clinique des médecins ne comportent que peu de matériel éducatif sur les MCV propre à chaque sexe et à chaque genre. Il est possible que l'irrégularité des programmes de formation intégrés des écoles de médecine au Canada contribue aux disparités persistantes dans les soins prodigués aux femmes et les résultats cliniques obtenus chez celles-ci, comparativement aux hommes. Pour combler cette lacune, le Groupe de travail sur la formation et l'éducation de l'Alliance canadienne de santé cardiaque pour les femmes a entrepris la planification, la préparation et la diffusion de l'Initiative nationale de sensibilisation à la santé cardiaque des femmes. La conception de l'Initiative a été guidée par une approche en six volets axée sur l'élaboration d'un programme de formation médicale, qui comprenait une évaluation des besoins, la détermination et la hiérarchisation du contenu, la formulation des buts et des objectifs, la sélection des stratégies de formation, ainsi que la mise en œuvre et les modalités d'évaluation.

Gender-Based Differences in Outcomes Among Resuscitated Patients With Out-of-Hospital Cardiac Arrest.

BACKGROUND: Studies examining gender-based differences in outcomes of patients experiencing out-of-hospital cardiac arrest have demonstrated that, despite a higher likelihood of return of spontaneous circulation, women do not have higher survival. METHODS: Patients successfully resuscitated from out-of-hospital cardiac arrest enrolled in the CCC trial (Trial of Continuous or Interrupted Chest Compressions during CPR) were included. Hierarchical multivariable logistic regression models were constructed to evaluate the association between gender and survival after adjustment for age, gender, cardiac arrest rhythm, witnessed status, bystander cardiopulmonary resuscitation, episode location, epinephrine dose, emergency medical services response time, and duration of resuscitation. Do not resuscitate (DNR) and withdrawal of life-sustaining therapy (WLST) order status were used to assess whether differences in postresuscitation outcomes were modified by baseline prognosis. The analysis was replicated among ALPS trial (Amiodarone, Lidocaine, or Placebo in Out-of-Hospital Cardiac Arrest) participants. RESULTS: Among 4875 successfully resuscitated patients, 1825 (37.4%) were women and 3050 (62.6%) were men. Women were older (67.5 versus 65.3 years), received less bystander cardiopulmonary resuscitation (49.1% versus 54.9%), and had a lower proportion of cardiac arrests that were witnessed (55.1% versus 64.5%) or had shockable rhythm (24.3% versus 44.6%, P<0.001 for all). A significantly higher proportion of women received DNR orders (35.7% versus 32.1%, P=0.009) and had WLST (32.8% versus 29.8%, P=0.03). Discharge survival was significantly lower in women (22.5% versus 36.3%, P<0.001; adjusted odds ratio, 0.78 [95% CI, 0.66-0.93]; P=0.005). The association between gender and survival to discharge was modified by DNR and WLST order status such that women had significantly reduced survival to discharge among patients who were not designated DNR (31.3% versus 49.9%, P=0.005; adjusted odds ratio, 0.74 [95% CI, 0.60-0.91]) or did not have WLST (32.3% versus 50.7%, P=0.002; adjusted odds ratio, 0.73 [95% CI, 0.60-0.89]). In contrast, no gender difference in survival was noted among patients receiving a DNR order (6.7% versus 7.4%, P=0.90) or had WLST (2.8% versus 2.4%, P=0.93). Consistent patterns of association between gender and postresuscitation outcomes were observed in the secondary cohort. CONCLUSIONS: Among patients resuscitated after experiencing out-of-hospital cardiac arrest, discharge survival was significantly lower in women than in men, especially among patients considered to have a favorable prognosis.

Patient-Provider Communication Regarding Referral to Cardiac Rehabilitation.

This study investigated the dynamics of patient-provider communication in the cardiac rehabilitation (CR) referral process, to identify which aspects lead to CR participation. Semi-structured individual interviews were conducted with 31 patients eligible for CR. Questions probed the content and perception of the discussion that patients had with healthcare providers (HCP) regarding CR attendance. The interviews were audiotaped, transcribed, and imported into N6 software for grounded analyses. Key emerging themes were identified: illness perceptions; HCP encouragement; timing of discussion; and ease of referral. CR attenders were apt to self-advocate to ensure their enrollment in CR, whereas nonattenders were more likely to minimize the seriousness of their disease, and less likely to persevere to overcome obstacles in enrolling in a CR program. Surprisingly, the strength of the HCP referral did not influence the decision to attend CR as strongly when compared to the HCP's ability to facilitate enrollment in a CR program.

N° 311 - Prise en charge de la ménopause (Résumé/Déclarations Sommaires et Recommandations).

OBJECTIF: Offrir, aux fournisseurs de soins de santé, une mise à jour de la directive clinique quant à la prise en charge de la ménopause chez les femmes asymptomatiques en santé, ainsi que chez les femmes qui présentent des symptômes vasomoteurs ou urogénitaux; cette mise à jour se penche également sur les facteurs associés à la maladie cardiovasculaire, au cancer du sein, à l'urogynécologie et à la sexualité. ISSUES: Les interventions quant au mode de vie, les médicaments d'ordonnance et les traitements de médecine complémentaire et parallèle sont présentés en fonction de leur efficacité dans la prise en charge des symptômes ménopausiques. Des stratégies de counseling et thérapeutiques en ce qui concerne les préoccupations en matière de sexualité au cours de la périménopause et de la postménopause sont passées en revue. Des approches quant à l'identification et à l'évaluation des femmes exposées à un risque élevé d'ostéoporose (ainsi que des options en matière de prévention et de traitement) sont présentées dans la directive clinique sur l'ostéoporose qui accompagne les présentes. RéSULTATS: La littérature publiée a été récupérée par l'intermédiaire de recherches menées dans PubMed et The Cochrane Library, en août et en septembre 2012, au moyen d'un vocabulaire contrôlé (p. ex. « hormone replacement therapy ¼, « menopause ¼, « cardiovascular diseases ¼ et « sexual function ¼) et de mots clés (p. ex. « HRT ¼, « perimenopause ¼, « heart disease ¼ et « sexuality ¼). Les résultats ont été restreints aux directives cliniques, aux analyses systématiques, aux essais comparatifs randomisés / essais cliniques comparatifs et aux études observationnelles. Les résultats ont également été restreints aux documents publiés, en anglais ou en français, à partir de 2009. Les recherches ont été mises à jour de façon régulière et intégrées à la directive clinique jusqu'au 5 janvier 2013. La littérature grise (non publiée) a été identifiée par l'intermédiaire de recherches menées dans les sites Web d'organismes s'intéressant à l'évaluation des technologies dans le domaine de la santé et d'organismes connexes, dans des collections de directives cliniques, dans des registres d'essais cliniques, auprès de sociétés de spécialité médicale nationales et internationales, et dans des collections de directives cliniques. VALEURS: La qualité des résultats est évaluée au moyen des critères décrits dans le rapport du Groupe d'étude canadien sur les soins de santé préventifs (Tableau 1).

Stroke in Patients With Peripheral Artery Disease.

Background and Purpose- Predictors of stroke and transient ischemic attack (TIA) in patients with peripheral artery disease (PAD) are poorly understood. The primary aims of this analysis were to (1) determine the incidence of ischemic/hemorrhagic stroke and TIA in patients with symptomatic PAD, (2) identify predictors of stroke in patients with PAD, and (3) compare the rate of stroke in ticagrelor- and clopidogrel-treated patients. Methods- EUCLID (Examining Use of Ticagrelor in Peripheral Artery Disease) randomized 13 885 patients with symptomatic PAD to receive monotherapy with ticagrelor or clopidogrel for the prevention of major adverse cardiovascular events (cardiovascular death, myocardial infarction, or ischemic stroke). Ischemic/hemorrhagic stroke and TIA were adjudicated and measured as incidence rates postrandomization and cumulative incidence (per patient-years). Post hoc multivariable competing risk hazards analyses were performed using baseline characteristics to determine factors associated with all-cause stroke in patients with PAD. Results- A total of 458 cerebrovascular events in 424 patients (317 ischemic strokes, 39 hemorrhagic strokes, and 102 TIAs) occurred over a median follow-up of 30 months, for a cumulative incidence of 0.87, 0.11, and 0.27 per 100 patient-years, respectively. Age, prior stroke, prior atrial fibrillation/flutter, diabetes mellitus, geographic region, ankle-brachial index <0.60, prior amputation, and systolic blood pressure were independent baseline factors associated with the occurrence of all-cause stroke. After adjustment for baseline factors, the rates of ischemic stroke and all-cause stroke remained lower in patients treated with ticagrelor as compared with those receiving clopidogrel. There was no significant difference in the incidence of hemorrhagic stroke or TIA between the 2 treatment groups. Conclusions- In patients with symptomatic PAD, ischemic stroke and TIA occur frequently over time. Comorbidities such as age, prior stroke, prior atrial fibrillation/flutter, diabetes mellitus, higher blood pressure, prior amputation, lower ankle-brachial index, and geographic region were each independently associated with the occurrence of all-cause stroke. Use of ticagrelor, as compared with clopidogrel, was associated with a lower adjusted rate of ischemic and all-cause stroke. Further study is needed to optimize medical management and risk reduction of all-cause stroke in patients with PAD. Clinical Trial Registration- URL: https://www.clinicaltrials.gov . Unique identifier: NCT01732822.

Hypertension in menopausal women: the effect and role of estrogen.

States of estrogen imbalance or deprivation are associated with higher risks of hypertension and cardiovascular disease in women; however, the effects of estrogen on hypertension are multifactorial, complex, and not completely understood. Although controversial, hormone therapy may improve cardiovascular outcomes when initiated by recently menopausal women. Improved screening for hypertension, especially in specific groups of younger women at higher risk, is recommended. Further study is needed to determine whether sex-specific differences exist in therapeutic response to pharmacologic management of hypertension.

Ticagrelor versus clopidogrel in patients with symptomatic peripheral artery disease and prior coronary artery disease: Insights from the EUCLID trial.

Patients with peripheral artery disease (PAD) are at heightened risk of cardiovascular morbidity and mortality. We sought to evaluate the risk of concomitant coronary artery disease (CAD) in patients with symptomatic PAD versus PAD without diagnosed CAD, and whether ticagrelor was superior to clopidogrel in reducing that risk. The EUCLID trial randomized 13,885 patients with PAD to antithrombotic monotherapy with ticagrelor or clopidogrel. CAD was defined as prior myocardial infarction (MI), percutaneous coronary intervention (PCI), or coronary artery bypass graft (CABG) surgery. Median follow-up was 30 months. Among 4032 (29%) patients with PAD and CAD, 63% had prior MI, 54% prior PCI, and 38% prior CABG. After adjustment for baseline characteristics, patients with PAD and CAD had significantly higher rates of the primary endpoint (cardiovascular death/MI/stroke, 15.3% vs 8.9%, hazard ratio (HR) 1.50, 95% CI: 1.13-1.99; p=0.005), but no statistically significant increase in acute limb ischemia (HR 1.28, 95% CI: 0.57-2.85; p=0.55) or major bleeding (HR 1.10, 95% CI: 0.49-2.48; p=0.81) versus PAD without CAD. Among patients with PAD and CAD, there was no differential treatment effect between ticagrelor versus clopidogrel for the primary efficacy endpoint (HR 1.02, 95% CI: 0.87-1.19; p=0.84), acute limb ischemia (HR 1.03, 95% CI: 0.63-1.69; p=0.89), or major bleeding (HR 1.06, 95% CI: 0.66-1.69; p=0.81). There was a statistically significant interaction between prior coronary stent placement and study treatment ( p=0.03) with a numerical reduction in the primary efficacy endpoint with ticagrelor versus clopidogrel (13.8% vs 16.8%, HR 0.82, 95% CI: 0.65-1.03; p=0.09). Patients with PAD and prior CAD had higher composite rates of cardiovascular death, MI, and ischemic stroke versus PAD without diagnosed CAD. There were no significant differences between ticagrelor and clopidogrel in cardiovascular events or major bleeding. ClinicalTrials.gov Identifier: NCT01732822.
