Background Hypertensive disorders of pregnancy (HDP) are a leading global cause of maternal and fetal morbidity/mortality. Most estimates of HDP occurrence are reported for composite exposures of HDP or preeclampsia alone, with limited disaggregation by obstetrical subgroup (eg, multi‐fetal deliveries). Consequently, our understanding of HDP prevalence and temporal trends remains limited, and methods for identifying specific diagnoses in administrative data remain underexamined. This population‐based descriptive study assessed how enhanced administrative case‐finding definitions influence prevalence estimates of HDP in pregnancy and postpartum. Methods Included were individuals aged ≥18 years discharged from an Ontario hospital following their first obstetrical delivery between April 1, 2002, and December 31, 2017. We calculated overall and annual prevalence estimates and assessed temporal trends for any HDP and major subtypes by case‐finding definitions, stratified by plurality (singleton versus multi‐fetal deliveries). Results Most subjects had a singleton first delivery (n=781 258; 98%); however, HDP was 2.2 to 2.4 times more prevalent in multi‐fetal deliveries. When pre‐pregnancy hypertension was considered during case‐finding, HDP prevalence increased from 193.6 to 207.6 per 1000 multi‐fetal deliveries and from 79.9 to 92.6 per 1000 singleton deliveries. Gestational hypertension was the most common diagnosis in both populations but was nearly twice as common in those who delivered a multiple gestation (94.4–100.0 versus 49.7–53.4 per 1000 deliveries). Prevalence trends differed by coding strategy and plurality. Conclusions Although informative, data from discharge abstracts alone are insufficient for HDP surveillance, particularly for chronic hypertension in pregnancy. Validation studies should assess the accuracy of our case‐finding definitions against suitable reference standards.

Thoracic aortic aneurysm (TAA) is a relatively common, under-recognised and lethal condition. Yet, current management remains anchored on absolute diameter for prophylactic repair, despite many dissections occurring below surgical thresholds—particularly in women. This review synthesises evidence showing that while rigorous standardisation of imaging is foundational, diameter alone is insufficient for accurate risk prediction. We appraise clinically available biomarkers beyond size: indexed metrics (Aortic Size Index, Aortic Height Index, Indexed Aortic Area) that adjust for body habitus—especially relevant in women; morphological descriptors (ascending length, arch tortuosity, aortic volume) that capture geometry; dynamic and biomechanical measures (growth rate, regional deformation, distensibility/stiffness) that reflect disease activity and advanced modalities (four-dimensional flow MRI, vascular deformation mapping) that quantify haemodynamics such as flow displacement and wall shear stress. Functional aortic markers—including central blood pressure, aortic stiffness, pulsatile arterial load and arterial age—independently predict expansion and improve risk stratification when combined with diameter. Furthermore, recognition of sex differences in TAA growth and outcomes supports sex-informed, precision aortic imaging and functional approaches to risk assessment. Future priorities include prospective multicentre validation, actionable sex-specific thresholds and multidisciplinary collaboration to translate these tools into personalised surveillance and timely intervention.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome, predominantly affecting women. Psychological distress is common pre- and post-SCAD, yet sex-specific patterns remain understudied. This cross-sectional study aimed to examine sex differences in the psychological distress of patients with SCAD. METHODS: Adult patients diagnosed with SCAD within the past 3 years, confirmed by coronary angiography, were recruited from 6 Canadian hospitals between April 2022 and January 2025. Participants completed questionnaires assessing sociodemographics and validated measures of psychological distress: Patient Health Questionnaire-9 for depression, Generalized Anxiety Disorder-7 for generalized anxiety, Cardiac Anxiety Questionnaire for cardiac-related anxiety, and PTSD Checklist-5 for posttraumatic stress symptoms. Sex differences were analyzed using t tests for continuous variables and χ 2 tests for categorical variables. Multivariable linear regression models assessed the association between sex and psychological distress, adjusting for age, pre-SCAD mental health diagnosis, and employment status. RESULTS: Among 326 patients (92.9% women; mean age=53.3±11.1 years), women reported higher rates of preexisting mental health conditions (29.2% versus 8.7%; P =0.035). Post-SCAD women reported higher mean scores than men on the Patient-Health-Questionnaire-9, Cardiac-Anxiety-Questionnaire, and PTSD Checklist-5 (all P <0.05). Female sex was associated with greater depressive (B=2.94; P =0.010), cardiac anxiety (B=7.09; P =0.008), and posttraumatic stress symptoms (B=5.94; P =0.048) after adjustment. Clinically significant symptoms were more common in women versus men: 25.1% versus 0% (depression), 21.5% versus 4.4% (anxiety), 54.8% versus 26.1% (cardiac anxiety), and 15.5% versus 0% (posttraumatic stress). CONCLUSIONS: Both women and men experience clinically significant cardiac anxiety following SCAD, but women report a greater psychological burden, including more preexisting mental health conditions and twice the distress after SCAD. These results underscore the importance of routine psychological screening and timely intervention to support mental health and recovery outcomes, particularly among women.

Background: Spontaneous Coronary Artery Dissection (SCAD) is a cause of acute coronary syndrome, particularly among women, and is associated with psychological distress, including depression, anxiety, and post-traumatic stress (PTSD) symptoms. Fibromuscular dysplasia (FMD), a vascular condition that alters the arteries, is often found in patients with SCAD, adding complexity and uncertainty with a second serious diagnosis. This study examined the differences in mental health symptoms between SCAD survivors with and without FMD to better understand their unique psychosocial needs and inform interventions to enhance patient outcomes. Methods: Patients diagnosed with SCAD within the past 3 years were recruited from 6 Canadian cardiac hospitals. Participants completed questionnaires assessing socio-demographics, comorbidities, and validated psychological measures, including Patient Health Questionnaire-9 (PHQ-9) for depression, Generalized Anxiety Disorder-7 (GAD-7) for generalized anxiety, Cardiac Anxiety Questionnaire (CAQ) for cardiac-related anxiety, and PTSD Checklist (PCL-5) for PTSD symptoms. Differences in mental health outcomes between SCAD survivors with and without FMD were analyzed using t-tests for continuous variables and chi-square tests for categorical variables. Results: The study included 326 participants (92.9% female; mean age 53.3 years), with 67 participants (20.6%) having a confirmed diagnosis of FMD at the time of questionnaire completion (39.3% FMD at study completion). Post-SCAD, patients with FMD reported significantly higher scores than patients without FMD on the GAD-7 (6.4±5.9 vs. 4.7±4.9, p = .028), CAQ (29.9±13.1 vs. 26.0±12.3, p = .023), and PCL-5 (17.2±15.4 vs. 13.3± 14.0, p = .048). The proportion of SCAD survivors with FMD scoring in the clinically diagnostic range was significantly higher than those in patients without FMD: 32.8% vs. 20.8% for depression, 31.3% vs. 17.4% for anxiety, 64.2% vs. 49.2% for cardiac anxiety, and 25.4% vs. 11.6% for PTSD (all p < .05). Conclusions: Our findings suggest that SCAD survivors with comorbid FMD experience significantly higher distress —depression, generalized anxiety, cardiac-related anxiety, and PTSD symptoms—compared to those without FMD. Longitudinal research is needed to explore the role of these mental health concerns in long-term mental health and cardiac outcomes. Enhanced psychological interventions for those with FMD may be required.

Abstract Aims Although cardiovascular disease (CVD) screening and preventive care in the early postpartum are recommended for women with prior gestational diabetes (GDM) and hypertensive disorders of pregnancy (HDP), certain barriers limit access to such services. We conducted a scoping review to summarize evidence on the barriers and facilitators of CVD prevention services among women with prior GDM or HDP. Methods and results A comprehensive search strategy was used to search articles published in three databases (Ovid Medline, CINAHL, Embase). Studies published in English or French that investigated and reported barriers or facilitators to postpartum CVD screening and preventive care among women with previous GDM and HDP were included. Out of 18 565 studies we screened, 29 studies (12 qualitative, 17 quantitative) were included. Main individual level barriers including lack of knowledge, health, and emotional factors were identified. Competing priorities, lack of family/friend support, and mistrust of healthcare providers were the most reported interpersonal level barriers, while gaps in communication were the most significant organizational barrier, and gaps in insurance coverage was the most reported system barrier. Individual level facilitators included a personal desire for better health and availability of postpartum programmes, and the most reported interpersonal facilitator was women's commitment to modelling a healthy lifestyle for their children. Organizational level facilitators were access to primary care providers and follow-up visit reminders, and programme availability in native languages. Conclusion Women with prior GDM or HDP face significant barriers to accessing postpartum CVD prevention services. These barriers ranged from individual-level knowledge gaps to system-level healthcare disparities.

Abstract Aims Aortic regurgitation (AR) arises from leaflet disease and/or dilatation of the functional aortic annulus complex. Understanding the mechanisms of AR informs surgical planning of valve and aorta repair. This study investigates the mechanisms, aetiologies, and outcomes of isolated native severe AR in a consecutive cohort of patients. Methods and results Patients with moderate-to-severe (3+)/severe (4+) native valve AR, identified from our institutional echocardiography database (2014–2018), were included. Exclusions were significant concomitant valve disease, endocarditis, or aortic dissection. AR was classified per the El-Khoury system: Type I (normal leaflet motion: Ia–ascending aorta/sinotubular junction dilatation, Ib–aortic root dilation, Ic–aortic annular dilation), Type II (leaflet prolapse), and Type III (leaflet restriction). Valve anatomy and clinical outcomes, including mortality and surgical intervention, were analyzed. Of 282 patients (77.3% male), 58.5% had multiple AR mechanisms. Type II (leaflet prolapse) was most common (48.6%), followed by Type III (36.2%). Bicuspid aortic valve (BAV) represented 35.5% of the population, with leaflet prolapse observed in 72%. Multiple mechanisms were more frequent in BAV (77% vs. 48%, P &lt; 0.001). After a median follow-up of 4.7 years (available for 97.5% of patients), 158 (57.5%) underwent an intervention with 48.7% having an aortic valve repair or valve-sparing aortic root replacement. Conclusion Although leaflet prolapse (Type II) was the pre-dominant AR mechanism, multiple contributing mechanisms were often present, particularly in BAV patients. Aortic valve repair accounted for nearly half of surgical interventions, underscoring the importance of mechanism identification to optimize repair and avoid valve replacement.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are a major cause of maternal morbidity and mortality and are associated with acute cardiac events in the peripartum period, as well as cardiovascular disease later in life. Despite the robust association between hypertension and atrial fibrillation (AFib), comparatively little is known about HDP and its subtypes as sex-specific risk factors for AFib. METHODS: A population-based retrospective cohort study was conducted, including 771 521 nulliparous women discharged for obstetrical delivery of their first live or stillborn singleton infant between 2002 and 2017 in Ontario, Canada. Data were obtained from record-level, coded, and linked population-based administrative databases housed at ICES. Using competing risks Cox proportional hazards regression, we estimated crude and multivariable-adjusted cause-specific hazard ratios and 95% CIs for associations between history of any HDP (and its 6 subtypes), and AFib before death, as well as all-cause mortality without a previous AFib diagnosis. RESULTS: Approximately 8% of women were diagnosed with HDP during the 16-year exposure accrual period. The total person-time of follow-up was 7 380 304 person-years, during which there were 2483 (0.3%) incident AFib diagnoses and 2951 (0.4%) deaths. History of any HDP was associated with an increased cause-specific hazard ratios of incident AFib and death without a previous AFib diagnosis (adjusted cause-specific hazard ratios, 1.45 [95% CI, 1.28–1.64] and 1.31 [95% CI, 1.16–1.47], respectively). These associations were observed in relatively young women (median time to event, 7 years postpartum). Associations suggestive of a dose-response relationship were observed, with more severe HDP subtypes and prepregnancy chronic hypertension associated with a 1.5 to 2.2 times higher cause-specific rate of AFib, and a 1.4 to 2.1 times higher cause-specific rate of death compared with no hypertension in pregnancy. CONCLUSIONS: Women exposed to HDP in their first delivery have a significantly increased cause-specific hazard ratios of incident AFib compared to their unexposed counterparts, with higher rates observed in subjects exposed to more severe de novo HDP diagnoses as well as chronic hypertension in pregnancy. These findings underscore the need to consider HDP history in risk calculation/stratification for arrhythmic and nonarrhythmic cardiovascular diseases, improve surveillance of traditional and female-specific cardiovascular disease risk factors, and develop targeted prevention strategies to reduce the occurrence and burden of HDP.
