RESUMEN
INTRODUCTION: Female patients are at elevated risk for adverse mental health outcomes following hospital admission for ischemic heart disease. These psychosocial characteristics are correlated with unacceptably higher rates of cardiovascular (CV) morbidity and mortality. Guidelines to address mental health following acute coronary syndrome (ACS) can only be developed with the aid of studies elucidating which subgroups of female patients are at the highest risk. METHODS/DESIGN: The Female Risk factors for post-Infarction Depression and Anxiety (FRIDA) Study is a prospective multicenter questionnaire-based study of female participants admitted to hospital with ACS. Data are collected within 72 h of admission as well as at 3 and 6 months. At baseline, participants complete a sociodemographic questionnaire, social support survey, and Hospital Depression and Anxiety Scale (HADS). Follow-up will consist of a demographic questionnaire, HADS, changes to health status, and quality of life indicators. Statistical analysis will include descriptive and inferential methods to observe baseline distributions and significance between groups. DISCUSSION/CONCLUSION: Our primary outcome is to determine if specific CV and sociodemographic factors correlate with increased depression and anxiety scores (HADS-D >7; HADS-A >7) at baseline. Our secondary aim is to determine if increased HADS scores at baseline and follow-up correlate with 3 and 6-month health and quality of life outcomes. A total of 2,000 patients will be enrolled across seven study sites. The aim of the FRIDA Study is to understand which groups of female patients have the highest rates of depression and anxiety following ACS to better inform care.

BACKGROUND: Myocardial infarction with nonobstructive coronary arteries (MINOCA) occurs in 6% to 15% of myocardial infarctions (MIs) and disproportionately affects women. Scientific statements recommend multimodality imaging in MINOCA to define the underlying cause. We performed coronary optical coherence tomography (OCT) and cardiac magnetic resonance (CMR) imaging to assess mechanisms of MINOCA. METHODS: In this prospective, multicenter, international, observational study, we enrolled women with a clinical diagnosis of myocardial infarction. If invasive coronary angiography revealed <50% stenosis in all major arteries, multivessel OCT was performed, followed by CMR (cine imaging, late gadolinium enhancement, and T2-weighted imaging and T1 mapping). Angiography, OCT, and CMR were evaluated at blinded, independent core laboratories. Culprit lesions identified by OCT were classified as definite or possible. The CMR core laboratory identified ischemia-related and nonischemic myocardial injury. Imaging results were combined to determine the mechanism of MINOCA, when possible. RESULTS: Among 301 women enrolled at 16 sites, 170 were diagnosed with MINOCA, of whom 145 had adequate OCT image quality for analysis; 116 of these underwent CMR. A definite or possible culprit lesion was identified by OCT in 46.2% (67/145) of participants, most commonly plaque rupture, intraplaque cavity, or layered plaque. CMR was abnormal in 74.1% (86/116) of participants. An ischemic pattern of CMR abnormalities (infarction or myocardial edema in a coronary territory) was present in 53.4% (62/116) of participants undergoing CMR. A nonischemic pattern of CMR abnormalities (myocarditis, takotsubo syndrome, or nonischemic cardiomyopathy) was present in 20.7% (24/116). A cause of MINOCA was identified in 84.5% (98/116) of the women with multimodality imaging, higher than with OCT alone (P<0.001) or CMR alone (P=0.001). An ischemic cause was identified in 63.8% of women with MINOCA (74/116), a nonischemic cause was identified in 20.7% (24/116) of the women, and no mechanism was identified in 15.5% (18/116). CONCLUSIONS: Multimodality imaging with coronary OCT and CMR identified potential mechanisms in 84.5% of women with a diagnosis of MINOCA, 75.5% of which were ischemic and 24.5% of which were nonischemic, alternate diagnoses to myocardial infarction. Identification of the cause of MINOCA is feasible and has the potential to guide medical therapy for secondary prevention.

BACKGROUND: Ranolazine is approved in the United States and Europe for chronic stable angina. Microvascular angina (MVA) is defined as angina with no obstructive coronary artery disease. STUDY QUESTION: Our objective was to assess the effectiveness of ranolazine at improving angina scores and quality of life in a Canadian cohort with severe refractory angina due to MVA. STUDY DESIGN: We administered questionnaires to 31 patients at baseline and after at least 6 weeks of ranolazine treatment. MEASURES AND OUTCOMES: Validated, clinically significant changes for each Seattle Angina Questionnaire domain and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form were obtained from the literature. Score changes between baseline and postranolazine use were analyzed using sign test. RESULTS: Patients were mostly female (27 of 31 patients) with a median age of 57 years. After initiation of ranolazine treatment, patients experienced improvements in Quality of Life Enjoyment and Satisfaction Questionnaire Short Form scores (80.6%; P < 0.01) and in 3 of the 4 domains of the Seattle Angina Questionnaire (physical limitation: 73.3%; P = 0.02; treatment satisfaction: 80.6%; P < 0.01; and disease perception: 77.4%; P < 0.01). Patients were less likely to have interactions with the health care system after ranolazine treatment as compared with before (35.5% vs. 93.5%; P < 0.01). CONCLUSIONS: Ranolazine significantly improves symptom control and quality of life in patients with MVA and severe refractory angina and reduces their interaction with the health care system. Given the potentially debilitating effect of chronic angina in MVA, ranolazine may be an effective treatment option.

Endometriosis and atherosclerotic cardiovascular disease (ASCVD) are both essentially diseases of inflammation. It is well established that inflammation is the leading mechanism in the initiation and maintenance of vascular injury and in the development and progression of atherosclerosis. Thus, if women with endometriosis do indeed have increased general inflammation, they are at increased risk of developing microvascular dysfunction and atherosclerosis. Currently available evidence suggests that young female patients with proven endometriosis may be at a higher lifetime risk of developing cardiovascular disease; this may be unrecognized due to the relatively young age of women found to have endometriosis. Other mechanisms proposed to explain the link between endometriosis and ASCVD include similarities in the genetic underpinnings of each condition, including microRNA dysfunction and the association between endometriosis and early menopause, a risk for developing ASCVD. Although physicians today primarily focus on traditional risk factors when evaluating an individual female patient's risk of developing ASCVD, we believe that a history of endometriosis should be included as a possible risk factor and needs further exploration. A better understanding of the mechanisms linking endometriosis with ASCVD will hopefully guide the implementation of new therapies to mitigate the increased cardiovascular disease burden that patients with endometriosis might face.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an infrequent but important cause of myocardial infarction (MI) especially in younger women. However, the clinical presentation and the acuity of symptoms prompting invasive management in SCAD patients have not been described. Understanding these presenting features may improve SCAD diagnosis and management. METHODS: We reviewed SCAD patients who were prospectively followed at the Vancouver General Hospital SCAD Clinic. Their presenting symptoms and unstable features were obtained from detailed clinical histories and hospital admission documentation. Baseline characteristics, predisposing and precipitating conditions, angiographic findings, management strategies, in-hospital, and long-term events were recorded prospectively. RESULTS: We included 196 SCAD patients who had complete documentation of their presenting symptoms. The majority were women (178/196; 90.8%) and all presented with MI (24.0% STEMI). The most frequent presenting symptom was chest discomfort, reported by 96%. Other symptoms included arm pain (49.5%), neck pain (22.1%), nausea or vomiting (23.4%), diaphoresis (20.9%), dyspnea (19.3%), and back pain (12.2%). Ventricular tachycardia/fibrillation occurred in 8.1% (16/196), with 1.0% having cardiac arrest. The time from symptom onset to hospital presentation was 1.1 ± 3.0 days. NSTEMI patients had longer delay for coronary angiography compared with STEMI (2.0 ± 2.5 days vs. 0.8 ± 1.7 days, P = 0.002). Overall, 34.2% had unstable symptoms upon arrival for coronary angiography. Those with unstable symptoms were more likely to undergo repeat angiography (65.7% vs. 50.4%, P = 0.049), and repeat or unplanned revascularization (14.9% vs. 5.4%, P = 0.033) during acute hospitalization. CONCLUSION: Chest discomfort was the most frequent presenting symptom with SCAD and one-third had unstable symptoms prompting urgent invasive angiography. © 2017 Wiley Periodicals, Inc.

Background/Introduction: Self-management approaches are regarded as appropriate methods to support patients with cardiovascular disease (CVD) and to prevent secondary complications and hospitalizations. Key to successful self-management is the ability of individuals to enlist peer supports to help sustain motivation and efforts to manage their condition. The purpose of this study was to investigate the proof of concept of a peer-support mobile-health (m-health) program, called Healing Circles, and explore the program's effect on self-management, social support, and health-related quality of life in women with CVD. MATERIALS AND METHODS: Healing Circles is a consumer m-health solution developed to facilitate peer support and self-management by connecting people with CVD in groups of five to nine people. Women with CVD (obstructive coronary artery disease) were included in this single group, pre/post study if they owned an iPhone/iPad with at least iOS 7.0. Participants (n = 21) used the Healing Circles program for a 10-week period. Self-management, social support, and health-related quality-of-life outcomes were assessed before and after the use of the program. User experiences and satisfaction were obtained during an exit interview. RESULTS: After 10 weeks of using the Healing Circles program, statistically significant improvements were observed in the participants' health behaviors (p = 0.04), self-monitoring (p = 0.04), social support (p = 0.01), and social integration (p = 0.002). As well, many women had a level of high satisfaction with the concept of using m-health for the delivery of peer support. CONCLUSION: The delivery of peer and self-management support using m-health technologies is well received and may improve self-management and social support. More research is needed to test hypotheses of the effect of the Healing Circles program on clinical outcomes.

This article aims to bridge existing knowledge gaps that impact clinical cardiovascular care and outcomes for women in Canada. The authors discuss various aspects of women's heart health, emphasizing the efficacy of multidisciplinary care in promoting women's well-being. The article also identifies the impact of national women's heart health campaigns and the value of peer support in improving outcomes. The article addresses the particular risks that women face, such as pregnancy-related complications and hormone replacement therapy, all of which are associated with cardiovascular events, and highlights the differences in ischemic symptoms between men and women. Despite improvements in acute event outcomes, challenges persist in accessing timely ambulatory care, particularly for women. Canada has responded to these challenges by introducing Women Heart Programs, which offer tailored programs, support groups, and specialized testing. However, these programs remain few in number and are found only in urban settings. Overall, this review identifies sex and gender factors related to women's heart health, underscoring the importance of specialized programs and multidisciplinary care in improving women's cardiovascular health.
Cet article vise à répondre aux incertitudes actuelles qui se répercutent sur les soins cardiovasculaires et les issues cliniques chez les femmes au Canada. Les auteurs abordent différents aspects de la santé cardiaque des femmes, mettant l'accent sur l'efficacité des soins multidisciplinaires pour améliorer le bien-être des femmes. L'article présente également l'effet des campagnes nationales sur la santé cardiaque des femmes et l'importance de l'entraide entre collègues pour améliorer les résultats. L'article traite des risques particuliers touchant les femmes, comme les complications liées à la grossesse et l'hormonothérapie substitutive, qui sont toutes associées à des événements cardiovasculaires, et il souligne les différences entre les hommes et les femmes pour ce qui est des symptômes ischémiques. Bien que des améliorations aient été observées quant à l'issue des événements aigus, des difficultés persistent sur le plan de l'accès rapide à des soins ambulatoires, surtout pour les femmes. Le Canada a répondu à ces difficultés en créant des programmes pour la santé cardiaque des femmes, qui offrent des services adaptés, des groupes de soutien et des analyses spécialisées. Cependant, ils sont encore peu nombreux et accessibles seulement en milieu urbain. Dans l'ensemble, cette analyse définit les facteurs liés au sexe et au genre qui interviennent dans la santé cardiaque des femmes, soulignant l'importance de mettre en place des programmes spécialisés et des soins multidisciplinaires pour améliorer la santé cardiovasculaire des femmes.
RESUMEN
Background: Heart disease is the leading cause of premature death for women in Canada. Ischemic heart disease is categorized as myocardial infarction (MI) with no obstructive coronary artery disease (MINOCA), ischemia with no obstructive coronary arteries (INOCA), and atherosclerotic obstructive coronary artery disease (CAD) with MI (MI-CAD) or without MI (non-MI-CAD). This study aims to study the prevalence of traditional and nontraditional ischemic heart disease risk factors and their relationships with (M)INOCA, compared to MI-CAD and non-MI-CAD in young women. Methods: This study investigated women who presented with premature (at age ≤ 55 years) vasomotor entities of (M)INOCA or obstructive CAD confirmed by coronary angiography, who are currently enrolled in either the Leslie Diamond Women's Heart Health Clinic Registry (WHC) or the Study to Avoid Cardiovascular Events in British Columbia (SAVEBC). Univariable and multivariable regression models were applied to investigate associations of risk factors with odds of (M)INOCA, MI-CAD, and non-MI-CAD. Results: A total of 254 women enrolled between 2015 and 2022 were analyzed, as follows: 77 with INOCA and 37 with MINOCA from the registry, and 66 with non-MI-CAD and 74 with MI-CAD from the study. Regression analyses demonstrated that migraines and preeclampsia or gestational hypertension were the most significant risk factors, with a higher likelihood of being associated with premature (M)INOCA, relative to obstructive CAD. Conversely, the presence of diabetes and a current or previous smoking history had the highest likelihood of being associated with premature CAD. Conclusions: The risk factor profiles of patients with premature (M)INOCA, compared to obstructive CAD, have significant differences.
Contexte: Au Canada, la cardiopathie est la principale cause de décès prématuré chez les femmes. La cardiopathie ischémique est catégorisée comme suit : infarctus du myocarde (IM) en l'absence de coronaropathie obstructive (MINOCA), ischémie sans obstruction des artères coronaires (INOCA) et athérosclérose coronaire obstructive accompagnée d'un IM ou sans IM. La présente étude vise à examiner la prévalence des facteurs de risque classiques et non classiques de cardiopathie ischémique et leurs liens avec le (M)INOCA, comparativement à l'athérosclérose coronaire obstructive accompagnée d'un IM ou sans IM chez les femmes jeunes. Méthodologie: Cette étude portait sur des femmes qui avaient prématurément (55 ans ou moins) souffert d'un (M)INOCA ou d'une coronaropathie obstructive confirmés par coronarographie et qui étaient inscrites au registre de la Leslie Diamond Women's Heart Health Clinic (WHC) ou qui participaient à l'étude visant à éviter les événements cardiovasculaires en Colombie-Britannique (Study toAvoid CardiovascularEvents inBC; SAVEBC). Des modèles de régression univariés et multivariés ont été utilisés pour explorer les associations entre les facteurs de risque et les probabilités de (M)INOCA, ainsi que d'athérosclérose coronaire obstructive accompagnée ou non d'un IM. Résultats: Au total, 254 femmes inscrites de 2015 à 2022 ont été recensées, soit 77 présentant une INOCA et 37, un MINOCA selon le registre WHC, et 66 présentant une athérosclérose coronaire obstructive sans IM et 74, une athérosclérose coronaire obstructive accompagnée d'un IM selon l'étude SAVEBC. Les analyses de régression ont démontré que les migraines et la prééclampsie ou l'hypertension gestationnelle étaient les facteurs de risque les plus importants associés à une probabilité la plus élevée de (M)INOCA comparativement à une coronaropathie obstructive. En revanche, la présence d'un diabète et d'un tabagisme actuel ou passé était associée à la probabilité la plus élevée de coronaropathie prématurée. Conclusions: Il existe d'importantes différences pour ce qui est des profils de facteurs de risque des patientes ayant prématurément souffert d'un (M)INOCA en comparaison d'une coronaropathie obstructive.
RESUMEN
Background: Screening first-degree relatives (FDRs) of patients with premature coronary artery disease (CAD) is recommended but not routinely performed. Objectives: To assess the diagnostic yield and impact on clinical management of a clinical and imaging-based screening program of FDRs delivered in the setting of routine clinical care. Methods: We recruited FDRs of patients with premature CAD with no personal history of CAD and prospectively assessed for: 1) cardiovascular risk and presence of significant subclinical atherosclerosis (SA) defined as plaque on carotid ultrasound, stenosis >50% or extensive atherosclerosis on coronary computed tomography angiography, or coronary artery calcium scores >100 Agatston units or >75% percentile for age and sex; 2) utilization of preventive medications and lipid levels prior enrolment and after completion of the assessment. Results: We assessed 132 FDRs (60.6% females), mean (SD) age 47(17) years old. Cardiovascular risk was high in 38.2%, moderate in 12.2%, and low in 49.6% of FDRs. SA was present in 34.1% of FDRs, including 12.5% in low, 51.9% in moderate, and 55.0% in high calculated risk groups. After assessment, LLT was initiated in 32.6% of FDRs and intensified in 16.0% leading to mean (SD) LDL-C decrease of 1.07(1.10) mmol/L in patients with high calculated risk or SA. LLT was recommended to all patients with high calculated risk, but those with SA were more likely to receive the medications from pharmacies (93.3% vs 60.0%, p = 0.006). Conclusion: Screening the FDRs of patients with premature CAD is feasible, may have high diagnostic yield and impact risk factor management.
RESUMEN
Myocardial infarction with no obstructive coronary artery disease (MINOCA) represents 6%-15% of all acute coronary syndromes, and women are disproportionately represented. MINOCA is an encompassing preliminary diagnosis, and emerging evidence supports a more expansive comprehensive diagnostic and therapeutic clinical approach. The current clinical practice update summarizes the latest evidence regarding the epidemiology, clinical presentation, and diagnostic evaluation of MINOCA. A cascaded approach to diagnostic workup is outlined for clinicians, for noninvasive and invasive diagnostic pathways, depending on clinical setting and local availability of diagnostic modalities. Evidence concerning the nonpharmacological and pharmacological treatment of MINOCA are presented and summarized according to underlying cause of MINOCA, with practical tips on the basis of expert opinion, outlining a real-life, evidence-based, comprehensive approach to management of this challenging condition.

BACKGROUND: We comparatively evaluated clinical outcomes in men and women presenting with stable angina with no coronary artery disease (CAD), nonobstructive CAD, and obstructive CAD on coronary angiography. METHODS: We studied all patients ≥20 years with stable angina, undergoing coronary angiography in British Columbia, Canada, from July 1999 to December 2002 (n = 13,695) with maximum follow-up to 3 years. No CAD, nonobstructive CAD, and obstructive CAD were defined as 0%, 1% to 49%, and ≥50% luminal narrowing in any epicardial coronary artery, respectively. Freedom from major adverse cardiac events (MACEs), which included the combined end points of all-cause mortality, nonfatal acute myocardial infarction, nonfatal stroke, and heart failure admissions, was estimated using the Kaplan-Meier method. Hazard ratios (HRs) and 95% CIs for MACE were estimated up to 3 years postcatheterization and compared between sex and CAD groups. RESULTS: Within the first year, women with nonobstructive CAD had a higher risk of MACE than men with nonobstructive CAD (adjusted HR 2.43, 95% CI 1.08-5.49). Furthermore, women with nonobstructive CAD had a 2.55-fold higher risk of MACE than women with no CAD (95% CI 1.33-4.88). In contrast, men with nonobstructive CAD had a similar risk as men with no CAD (adjusted HR 0.61, 95% CI 0.26-1.45). The differences in MACE according to extent of CAD were not evident in the longer term. CONCLUSIONS: Women with stable angina and nonobstructive CAD are 3 times more likely to experience a cardiac event within the first year of cardiac catheterization than men. A prospective trial to examine the impact of medical therapy on MACE in patients with nonobstructive CAD is warranted.

BACKGROUND: A prolonged corrected QT (QTc) interval is a marker for an increased risk of sudden cardiac death. We evaluated the relationship between oral contraceptive (OC) use, type of OC, and QTc interval. METHODS: We identified 410,782 ECGs performed at Northern California Kaiser Permanente on female patients between 15 and 53 years from January, 1995 to June, 2008. QT was corrected for heart rate using log-linear regression. OC generation (first, second and third) was classified by increasing progestin androgenic potency, while the fourth generation was classified as antiandrogenic. RESULTS: Among 410,782 women, 8.4% were on OC. In multivariate analysis after correction for comorbidities, there was an independent shortening effect of OCs overall (slope = -0.5 ms; SE = 0.12, P < 0.0002). Users of first and second generation progestins had a significantly shorter QTc than nonusers (P < 0.0001), while users of fourth generation had a significantly longer QTc than nonusers (slope = 3.6 ms, SE = 0.35, P < 0.0001). CONCLUSION: Overall, OC use has a shortening effect on the QTc. Shorter QTc is seen with first and second generation OC while fourth generation OC use has a lengthening effect on the QTc. Careful examination of adverse event rates in fourth generation OC users is needed.

Mortality rates for cardiovascular disease are higher in women than in men, but studies of women have been conducted less frequently. Current pharmacological and nonpharmacological treatment options for women with stable angina are reviewed.
RESUMEN
Defined as a prejudice either for or against something, biases at the provider, patient, and societal level all contribute to differences in cardiovascular disease recognition and treatment, resulting in outcome disparities between sexes and genders. Provider bias in the under-recognition of female-predominant cardiovascular disease and risks might result in underscreened and undertreated patients. Furthermore, therapies for female-predominant phenotypes including nonobstructive coronary artery disease and heart failure with preserved ejection fraction are less well researched, contributing to undertreated female patients. Conversely, women are less likely to seek urgent medical attention, potentially related to societal bias to put others first, which contributes to diagnostic delays. Furthermore, women are less likely to have discussions around risk factors for coronary artery disease compared with men, partially because they are less likely to consider themselves at risk for heart disease. Provider bias in interpreting a greater number of presenting symptoms, some of which have been labelled as "atypical," can lead to mislabelling presentations as noncardiovascular. Furthermore, providers might avoid discussions around certain therapies including thrombolysis for stroke, and cardiac resynchronization therapy in heart failure, because it is incorrectly assumed that women are not interested in pursuing options deemed more invasive. To mitigate bias, organizations should aim to increase the visibility and involvement of women in research, health promotion, and clinical and leadership endeavours. More research needs to be done to identify effective interventions to mitigate sex and gender bias and the resultant cardiovascular outcome discrepancies.

Background: Constrictive pericarditis (CP) is a rare condition in which the pericardium becomes progressively fibrotic and non-compliant leading to impaired ventricular filling and overt heart failure. While CP shares many clinical and haemodynamic similarities with restrictive cardiomyopathy, differentiation of these diseases is crucial as CP is potentially curative through pericardiectomy. Here, we present a case of proven pericardial constriction with atypical haemodynamics in a patient presenting with heart failure and severe left main coronary artery disease (CAD). Case summary: A 69-year-old female with a history of hypertension and paroxysmal atrial fibrillation presented with persistent heart failure refractory to diuretics. Ischaemic and infiltrative work-up were found to be negative with magnetic resonance imaging demonstrating trace pericardial fluid and thickening of the pericardium. Echocardiogram and right-heart catheterization demonstrated atypical haemodynamics suggestive of but not conclusive for CP, with coronary angiogram demonstrating severe left main CAD. Ultimately, the patient underwent coronary artery bypass grafting along with pericardiectomy and pericardial biopsy demonstrating constrictive physiology. Discussion: We suspect the inconclusive nature of the echocardiogram and cardiac catheterization was likely secondary to severe CAD impairing left ventricular relaxation and dampening ventricular interdependence. As such, clinicians should consider the possibility of coexistent severe CAD in patients with a clinical suspicion of CP, but inconclusive haemodynamics.
RESUMEN
BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of myocardial infarction (MI) that most frequently affects women. The characteristics of men with SCAD are less well described. OBJECTIVES: The aim of this study was to describe the characteristics of men with SCAD. METHODS: We compared baseline demographics, clinical presentation, angiographic findings and cardiovascular outcomes of men and women in the Canadian SCAD Study. Major adverse cardiovascular events (MACE) were composite of death, MI, stroke or transient ischemic attack, heart failure hospitalization, and revascularization. RESULTS: Of 1,173 patients with SCAD, 123 (10.5%) were men. Men with SCAD were younger than women (mean age 49.4 ± 9.6 years vs 52.0 ± 10.6 years; P = 0.01). Men had lower rate of prior MI than women (0.8% vs 7.0%; P = 0.005). Men were less likely to have fibromuscular dysplasia (FMD) (27.8% vs 52.7%; P = 0.001), depression (9.8% vs 20.2%; P = 0.005), emotional stress (35.0% vs 59.3%; P < 0.001), or high score on the Perceived Stress Scale (3.5% vs 11.0%; P = 0.025) but were more likely to report isometric physical stress (40.2% vs 24.0%; P = 0.007). There was no difference in angiographic types of SCAD, but men had more circumflex artery (44.4% vs 30.9%; P = 0.001) and fewer right coronary artery (11.8% vs 21.7%; P = 0.0054) dissections. At median follow-up of 3.0 (IQR: 2.0-3.8) years, men had fewer hospital presentations with chest pain (10.6% vs 24.8%; P < 0.001). There were no differences in in-hospital events or follow-up MACE (7.3% vs 12.7%; P = 0.106). CONCLUSIONS: Ten percent of SCAD patients were men. Men were younger and more likely to have a physical trigger but were less likely to have FMD, depression, or an emotional trigger. Men had less recurrent chest pain but no significant difference in MACE.

BACKGROUND: Many women with cardiac chest pain and ischemia or myocardial infarction have no obstructive coronary artery disease (INOCA or MINOCA). Studies suggest that these patients have a decreased quality of life and are at increased risk of cardiovascular events. Our study reports 1-year quality of life, frequency of angina, and outcomes following entry into a multidisciplinary Women's Heart Centre (WHC). METHODS: Patients with INOCA and MINOCA completed questionnaires on baseline demographics and clinical presentation. At 1-year, frequency of chest pain, quality of life, depression and anxiety symptoms, and cardiovascular outcomes were reported and compared with baseline. RESULTS: A total of 154 women with nonobstructive coronary artery disease were included in this study (112 patients with INOCA and 42 with MINOCA). Median age was 59 years, and the most common referral was for chest pain (94% in INOCA and 66% in MINOCA). At baseline, 64% of patients with INOCA and 43% of patients with MINOCA did not have specific diagnoses. Following investigations in the WHC, 71.4% of patients with INOCA established a new or a changed diagnosis (most common was coronary microvascular dysfunction at 68%), whereas 60% of patients with MINOCA established new or changed diagnoses (the most common of which was coronary vasospasm at 60%). At 1-year, participants had significantly decreased chest pain, improved quality of life, and improved mental health. CONCLUSIONS: A multidisciplinary WHC significantly increases the yield of a specific diagnosis in patients with INOCA and MINOCA. Further, attending a WHC could significantly improve the clinical and psychological outcomes of women with INOCA and MINOCA.

Up to 65% of women and approximately 30% of men have ischemia with no obstructive coronary artery disease (CAD; commonly known as INOCA) on invasive coronary angiography performed for stable angina. INOCA can be due to coronary microvascular dysfunction or coronary vasospasm. Despite the absence of obstructive CAD, those with INOCA have an increased risk of all-cause mortality and adverse outcomes, including recurrent angina and cardiovascular events. These patients often undergo repeat testing, including cardiac catheterization, resulting in lifetime healthcare costs that rival those for obstructive CAD. Patients with INOCA often remain undiagnosed and untreated. This review discusses the symptoms and prognosis of INOCA, offers a systematic approach to the diagnostic evaluation of these patients, and summarizes therapeutic management, including tailored therapy according to underlying pathophysiological mechanisms.
Jusqu'à 65 % des femmes et environ 30 % des hommes présentent une ischémie sans coronaropathie obstructive (INOCA [ischemia with no obstructive coronary artery disease]) révélée à la faveur d'une angiographie coronarienne invasive réalisée pour une angine stable. L'INOCA peut être attribuable à une dysfonction microvasculaire coronaire ou à un vasospasme coronaire. Malgré l'absence de coronaropathie obstructive, les patients atteints d'une INOCA présentent un risque accru de décès toutes causes confondues et d'événements indésirables, notamment l'angine récurrente et des événements cardiovasculaires. Ces patients sont souvent soumis à des examens répétés, dont le cathétérisme cardiaque, ce qui représente des dépenses de santé à vie qui rivalisent avec celles associées aux coronaropathies obstructives. Dans bien des cas, l'INOCA échappe au diagnostic et n'est pas traité. Dans le présent article de synthèse, nous nous penchons sur les symptômes et le pronostic de l'INOCA. Nous proposons une méthode systématique d'évaluation diagnostique de ces patients et résumons les modalités de sa prise en charge thérapeutique, notamment un traitement adapté aux mécanismes physiopathologiques sous-jacents.
RESUMEN
This Atlas chapter summarizes sex- and some gender-associated, and unique aspects and manifestations of cardiovascular disease (CVD) in women. CVD is the primary cause of premature death in women in Canada and numerous sex-specific differences related to symptoms and pathophysiology exist. A review of the literature was done to identify sex-specific differences in symptoms, pathophysiology, and unique manifestations of CVD in women. Although women with ischemic heart disease might present with chest pain, the description of symptoms, delay between symptom onset and seeking medical attention, and prodromal symptoms are often different in women, compared with men. Nonatherosclerotic causes of angina and myocardial infarction, such as spontaneous coronary artery dissection are predominantly identified in women. Obstructive and nonobstructive coronary artery disease, aortic aneurysmal disease, and peripheral artery disease have worse outcomes in women compared with men. Sex differences exist in valvular heart disease and cardiomyopathies. Heart failure with preserved ejection fraction is more often diagnosed in women, who experience better survival after a heart failure diagnosis. Stroke might occur across the lifespan in women, who are at higher risk of stroke-related disability and age-specific mortality. Sex- and gender-unique differences exist in symptoms and pathophysiology of CVD in women. These differences must be considered when evaluating CVD manifestations, because they affect management and prognosis of cardiovascular conditions in women.
Dans le présent chapitre d'Atlas sont récapitulés les aspects et les manifestations uniques, associés au sexe et certains associés au genre, des maladies cardiovasculaires (MCV) chez les femmes. Les MCV sont la cause principale de décès prématurés chez les femmes au Canada. De nombreuses différences quant aux symptômes et à la physiopathologie existent entre les sexes. Nous avons réalisé une revue de la littérature pour déterminer les différences entre les sexes dans les symptômes et la physiopathologie, et les manifestations uniques des MCV chez les femmes. Bien que les femmes atteintes d'une cardiopathie ischémique puissent éprouver des douleurs thoraciques, la description des symptômes, le délai entre l'apparition des symptômes et l'obtention de soins médicaux, et les symptômes prodromiques sont souvent différents de ceux des hommes. Les causes de l'angine et de l'infarctus du myocarde non liées à l'athérosclérose telles que la dissection spontanée de l'artère coronaire sont principalement observées chez les femmes. La coronaropathie obstructive et non obstructive, l'anévrisme aortique et la maladie artérielle périphérique montrent de plus mauvaises issues chez les femmes que chez les hommes. Des différences entre les sexes sont observées dans la cardiopathie valvulaire et les cardiomyopathies. Le diagnostic d'insuffisance cardiaque avec fraction d'éjection préservée est plus souvent posé chez les femmes qui présentent un meilleur taux de survie après un diagnostic d'insuffisance cardiaque. L'accident vasculaire cérébral (AVC) pourrait survenir tout au long de la vie des femmes, qui sont exposées à un risque plus élevé d'incapacités liées à l'AVC et de mortalité par âge. Il existe des différences uniques entre les sexes et les genres pour ce qui est des symptômes et de la physiopathologie des MCV chez les femmes. Lors de l'évaluation des manifestations des MCV, il faut tenir compte de ces différences puisqu'elles influencent la prise en charge et le pronostic des maladies cardiovasculaires chez les femmes.
