Abstract
BACKGROUND Mitral valve (MV) disease is the most common form of valvular heart disease. Findings that indicate women have a higher risk for unfavorable outcomes than men remain controversial. This study aimed to determine the sex-based differences in epidemiological distributions and outcomes of surgery for MV disease.Methods and Results: Overall, 18,572 patients (45.3% women) who underwent MV surgery between 2001 and 2018 were included. Outcomes included in-hospital death and all-cause mortality during follow up. Subgroup analysis was conducted across different etiologies, including infective endocarditis (IE), degenerative, ischemic, and rheumatic mitral pathology. The overall MV repair rate was lower in women than in men (20.5% vs. 30.6%). After matching, 6,362 pairs (woman : man=1 : 1) of patients were analyzed. Women had a slightly higher risk for in-hospital death than men (10.8% vs. 9.8%; odds ratio [OR]: 1.11, 95% confidence interval [CI]: 0.99-1.24; P=0.075). Women tended to have a higher incidence of de novo dialysis (9.8% vs. 8.6%; P=0.022) and longer intensive care unit stay (8 days vs. 7.1 days; P<0.001). Women with IE had poorer in-hospital outcomes than men; however, there were no sex differences in terms of all-cause mortality. CONCLUSIONS Sex-based differences of MV intervention still persist. Although long-term outcomes were comparable between sexes, women, especially those with IE, had worse perioperative outcomes than men.

Abstract
The incidence of premature myocardial infarction (PMI) has been rising and acute kidney injury (AKI) occurring in PMI patients severely impacts prognosis. This study aimed to develop and validate a prediction model for AKI specific to PMI patients. The MIMIC-Ⅲ-CV and MIMIC-Ⅳ databases were utilized for model derivation of PMI patients. Single-center data served for external validation. There were 571 and 182 AKI patients in the training set (n = 937) and external validation set (n = 292) cohorts, respectively. Finally, a 7-variable model consisting of: Sequential Organ Failure Assessment (SOFA) score, coronary artery bypass grafting (CABG), ICU stay time, loop diuretics, estimated glomerular filtration rate (eGFR) HCO3- and Albumin was developed, achieving an AUC of 0.85 (95% CI: 0.83-0.88) in the training set. External validation also confirmed model robustness. This model may assist clinicians in the early identification of patients at elevated risk for PMI. Further validation is warranted before clinical application.

Abstract
Despite significant progress in medical research and public health efforts, gaps in knowledge of women's heart health remain across epidemiology, presentation, management, outcomes, education, research, and publications. Historically, heart disease was viewed primarily as a condition in men and male individuals, leading to limited understanding of the unique risks and symptoms that women experience. These knowledge gaps are particularly problematic because globally heart disease is the leading cause of death for women. Until recently, sex and gender have not been addressed in cardiovascular research, including in preclinical and clinical research. Recruitment was often limited to male participants and individuals identifying as men, and data analysis according to sex or gender was not conducted, leading to a lack of data on how treatments and interventions might affect female patients and individuals who identify as women differently. This lack of data has led to suboptimal treatment and limitations in our understanding of the underlying mechanisms of heart disease in women, and is directly related to limited awareness and knowledge gaps in professional training and public education. Women are often unaware of their risk factors for heart disease or symptoms they might experience, leading to delays in diagnosis and treatments. Additionally, health care providers might not receive adequate training to diagnose and treat heart disease in women, leading to misdiagnosis or undertreatment. Addressing these knowledge gaps requires a multipronged approach, including education and policy change, built on evidence-based research. In this chapter we review the current state of existing cardiovascular research in Canada with a specific focus on women.

Abstract
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.

Abstract
Sex differences in coronary artery disease (CAD) presentation, risk factors and prognosis have been widely studied. Similarly, studies on atherosclerosis have shown prominent sex differences in plaque biology. Our understanding of the underlying genetic and molecular mechanisms that drive these differences remains fragmented and largely understudied. Through reviewing genetic and epigenetic studies, we identified more than 40 sex-differential candidate genes (13 within known CAD loci) that may explain, at least in part, sex differences in vascular remodeling, lipid metabolism and endothelial dysfunction. Studies with transcriptomic and single-cell RNA sequencing data from atherosclerotic plaques highlight potential sex differences in smooth muscle cell and endothelial cell biology. Especially, phenotypic switching of smooth muscle cells seems to play a crucial role in female atherosclerosis. This matches the known sex differences in atherosclerotic phenotypes, with men being more prone to lipid-rich plaques, while women are more likely to develop fibrous plaques with endothelial dysfunction. To unravel the complex mechanisms that drive sex differences in CAD, increased statistical power and adjustments to study designs and analysis strategies are required. This entails increasing inclusion rates of women, performing well-defined sex-stratified analyses and the integration of multi-omics data.

Abstract
BACKGROUND This study aimed to develop and validate an AI (artificial intelligence)-aid method in myocardial perfusion imaging (MPI) to differentiate ischemia in coronary artery disease. METHODS We retrospectively selected 599 patients who had received gated-MPI protocol. Images were acquired using hybrid SPECT-CT systems. A training set was used to train and develop the neural network and a validation set was used to test the predictive ability of the neural network. We used a learning technique named "YOLO" to carry out the training process. We compared the predictive accuracy of AI with that of physician interpreters (beginner, inexperienced, and experienced interpreters). RESULTS Training performance showed that the accuracy ranged from 66.20% to 94.64%, the recall rate ranged from 76.96% to 98.76%, and the average precision ranged from 80.17% to 98.15%. In the ROC analysis of the validation set, the sensitivity range was 88.9 ~ 93.8%, the specificity range was 93.0 ~ 97.6%, and the AUC range was 94.1 ~ 96.1%. In the comparison between AI and different interpreters, AI outperformed the other interpreters (most P-value < 0.05). CONCLUSION The AI system of our study showed excellent predictive accuracy in the diagnosis of MPI protocols, and therefore might be potentially helpful to aid radiologists in clinical practice and develop more sophisticated models.

Abstract
BACKGROUND Several studies have reported some sex differences in patients with coronary artery diseases. However, the results regarding long-term outcomes in patients with chronic coronary syndrome (CCS) are inconsistent. Therefore, the present study investigated sex differences in long-term outcomes in patients with CCS after percutaneous coronary intervention (PCI).Methods and Results: This was a retrospective, multicenter cohort study. We enrolled patients with CCS who underwent PCI between April 2013 and March 2019 using the Clinical Deep Data Accumulation System (CLIDAS) database. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, or hospitalization for heart failure. In all, 5,555 patients with CCS after PCI were included in the analysis (4,354 (78.4%) men, 1,201 (21.6%) women). The median follow-up duration was 917 days (interquartile range 312-1,508 days). The incidence of MACE was not significantly different between the 2 groups (hazard ratio [HR] 1.20; 95% confidential interval [CI] 0.97-1.47; log-rank P=0.087). After performing multivariable Cox regression analyses on 4 different models, there were still no differences in the incidence of MACE between women and men. CONCLUSIONS There were no significant sex differences in MACE in patients with CCS who underwent PCI and underwent multidisciplinary treatments.

Abstract
AIMS Cardiac rehabilitation (CR) not only improves cardiovascular outcomes, but also health-related quality of life (HRQOL). Unfortunately, CR is still underutilized, especially among women and older patients. Aim of this study was to highlight age- and sex-specific effects of inpatient CR on HRQOL. METHODS AND RESULTS From 2012 to 2018, 18 459 patients were prospectively assessed in six Swiss CR clinics. Of these, we retrospectively analysed a final sample of 8286 patients with a mean (standard deviation) age of 67.8 (11.3) in men and 72.2 (11.3) in women. HRQOL was measured at CR entry and discharge. In multivariable analyses, sex- and age-specific changes in HRQOL throughout CR were estimated, adjusting for baseline HRQOL and clinical characteristics. Participants of both sexes improved significantly (P < 0.001) in all domains of HRQOL during CR. Women reported significantly lower social (P < 0.001) and emotional (P < 0.001) HRQOL than men at CR entry. Female sex predicted greater improvement in social (F = 19.63, P < 0.001), emotional (F = 27.814, P < 0.001), and physical HRQOL (F = 20.473, P < 0.001). In a subgroup of n = 2632 elderly patients (>75 years), female sex predicted greater changes in emotional (F = 15.738, P < 0.001) and physical (F = 6.295, P = 0.012), but not in social HRQOL. CONCLUSION Women report poorer HRQOL at CR entry compared with men, but in turn particularly benefit from CR in this regard. Our results indicate that sex- and age-specific needs of patients should be considered.

Clinical Outcomes in Younger Women Hospitalized With an Acute Myocardial Infarction: A Contemporary Population-Level Analysis. Can J Cardiol 2022; 38:1651-1660. [PMID: 36334935 DOI: 10.1016/j.cjca.2022.06.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 06/18/2022] [Accepted: 06/23/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND For younger women with acute myocardial infarction (AMI), little is known regarding their contemporary care pathways and clinical outcomes. METHODS We studied AMI patients aged 18-55 years, hospitalized from April 1, 2009, to March 31, 2019, in Ontario, Canada. We compared trends in comorbidities, angiographic findings, and revascularisation rates in men and women. The primary outcome was 1-year all-cause mortality or readmission for unstable angina, AMI, heart failure, or stroke. Inverse probability of treatment weighting was used to account for differences in baseline clinical characteristics between men and women. RESULTS Among the 38,071 AMI patients included, 8,077 (21.2%) were women. Over the study period, women had increasing rates of diabetes (24.8% to 34.9%; Ptrend < 0.001), and declining rates of smoking (53.2% to 41.7%; Ptrend < 0.005). Although most patients received coronary angiography (96%), coronary revascularisation was less frequent among women than men (percutaneous coronary intervention: 61.9% vs 78.8% [P < 0.001]; surgery: 4.1% vs 6.0% [P < 0.001]). Women had more normal coronary anatomy (5.8% vs 1.7%; P < 0.001) and nonobstructive disease (22.8% vs 9.3%; P < 0.001) than men. Compared with men, the primary composite end point was significantly increased among women (10.0% vs 7.9%, adjusted HR 1.11; P = 0.02) and related to increased readmission rates for cardiovascular events. All-cause readmission was significantly increased among women (25.8% vs 21.1%, adjusted HR 1.34; P < 0.0001). CONCLUSIONS Coronary angiography is performed almost universally in younger women with AMI; however, coronary revascularisation is less frequent, perhaps reflecting less obstructive disease. Although mortality rates after AMI were similar between sexes, cardiovascular readmission rates and all-cause readmissions were significantly increased among women.

Abstract
Cardiovascular disease is a leading cause of morbidity and mortality in males and females in the United States and globally. Cardiac rehabilitation (CR) is recommended by the American Heart Association/American College of Cardiology for secondary prevention for patients with cardiovascular disease. CR participation is associated with improved cardiovascular disease risk factor management, quality of life, and exercise capacity as well as reductions in hospital admissions and mortality. Despite these advantageous clinical outcomes, significant sex disparities exist in outpatient phase II CR programming. This article reviews sex differences that are present in the spectrum of care provided by outpatient phase II CR programming (ie, from referral to clinical management). We first review CR participation by detailing the sex disparities in the rates of CR referral, enrollment, and completion. In doing so, we discuss patient, health care provider, and social/environmental level barriers to CR participation with a particular emphasis on those barriers that majorly impact females. We also evaluate sex differences in the core components incorporated into CR programming (eg, patient assessment, exercise training, hypertension management). Next, we review strategies to mitigate these sex differences in CR participation with a focus on automatic CR referral, female-only CR programming, and hybrid CR. Finally, we outline knowledge gaps and areas of future research to minimize and prevent sex differences in CR programming.

Abstract
OBJECTIVES Outcomes of sex differences in major cardiac surgery remain controversial. A comprehensive understanding of sex differences in major adult cardiac surgery could provide better knowledge of risk factors, management strategy and short-term or long-term outcomes. The present study aimed to investigate sex differences in the risks of outcomes of major cardiac surgeries and subgroup analyses of different valve types. DESIGN Population-based nationwide cohort study. SETTING Data were obtained from National Health Insurance Research Database (NHIRD) in Taiwan. PARTICIPANTS A total of 66 326 adult patients (age ≥20 years; 30.3% women) who underwent a first major cardiac surgery (isolated coronary artery bypass graft (CABG), isolated valve or concomitant bypass/valve) from 2000 to 2013 were identified via Taiwan NHIRD. MAIN OUTCOME MEASURES Outcomes of primary interest were in-hospital death and all-cause mortality during follow-up period. Propensity score matching was conducted as a secondary analysis for the sensitivity test. RESULTS Women who underwent isolated CABG tended to have greater risks of both in-hospital (OR 1.37; 95% CI 1.26 to 1.49) and late outcomes (HR 1.26; 95% CI 1.22 to 1.31). Women after concomitant CABG/valve also had a greater in-hospital (OR 1.19; 95% CI 1.01 to 1.40) and long-term mortality (HR 1.14; 95% CI 1.05 to 1.24). Women after isolated mitral valve repair have a non-favourable outcome of in-hospital mortality (OR 1.70; 95% CI 1.01 to 2.87). Women who did not receive an isolated aortic valve replacement had more favourable all-cause mortality outcome (HR 0.90; 95% CI 0.84 to 0.96). Secondary analysis in the propensity score-matching cohort demonstrated results similar to the primary analysis. CONCLUSIONS Female patients who underwent procedures involving CABG (with or without concurrent valvular intervention) had generally worse outcomes. However, the results of isolated valve surgery were variable on the basis of the type of intervened valve.

Knockdown of circ_0004104 Alleviates Oxidized Low-Density Lipoprotein-Induced Vascular Endothelial Cell Injury by Regulating miR-100/TNFAIP8 Axis. J Cardiovasc Pharmacol 2021; 78:269-279. [PMID: 34554678 DOI: 10.1097/fjc.0000000000001063] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 05/08/2021] [Indexed: 01/12/2023]
Abstract
ABSTRACT Coronary artery disease (CAD) is a common cardiovascular disease, mainly due to vascular endothelial cell (VEC) injury caused by atherosclerosis. Circular RNA has been shown to be involved in the regulation of various diseases. However, the role and mechanism of circ_0004104 in CAD are still unclear. Oxidized low-density lipoprotein (ox-LDL) was used to construct the VEC injury model in vitro. The expression levels of circ_0004104 and miR-100 were measured by quantitative real-time polymerase chain reaction. The proliferation of VECs was determined using 3-(45)-dimethylthiahiazo (-z-y1)-35-di-phenytetrazoliumromide assay and 5-ethynyl-2'-deoxyuridine staining assay. VEC apoptosis rate was assessed using flow cytometry, and caspase-3 activity was measured using a Caspase-3 Assay Kit. The protein expression levels of Ki-67, cleaved-caspase3, and tumor necrosis factor-α-induced protein 8 (TNFAIP8) were detected by western blot analysis. Furthermore, enzyme-linked immunosorbent assay was performed to assess the concentrations of inflammatory cytokines. In addition, the relationship between miR-100 and circ_0004104 or TNFAIP8 was confirmed by dual-luciferase reporter assay and biotin-labeled RNA pull-down assay. Our results revealed that circ_0004104 was upregulated and miR-100 was downregulated in patients with CAD and ox-LDL-induced VECs. Ox-LDL could inhibit the proliferation and promote the apoptosis and inflammation of VECs to induce VEC injury. However, silenced circ_0004104 could alleviate VEC injury induced by ox-LDL. Moreover, we found that circ_0004104 could sponge miR-100 and a miR-100 inhibitor could reverse the inhibition effect of circ_0004104 knockdown on ox-LDL-induced VEC injury. In addition, TNFAIP8 was a target of miR-100, and miR-100 alleviated ox-LDL-induced VEC injury by targeting TNFAIP8. Our data suggested that circ_0004104 promoted ox-LDL-induced VEC injury by the miR-100/TNFAIP8 axis, indicating that circ_0004104 might be a potential biomarker for CAD treatment.

Reproductive risk factors for angiographic obstructive coronary artery disease among postmenopausal women. ACTA ACUST UNITED AC 2021; 27:1403-1410.

Abstract
OBJECTIVE Reproductive factors are female-specific coronary artery disease (CAD) risk factors. However, the importance of reproductive factors in angiographic obstructive CAD in postmenopausal women remains uncertain. This study aimed to compare reproductive factors between postmenopausal women with no apparent CAD, nonobstructive CAD, and obstructive CAD and identify reproductive risk factors for obstructive CAD. METHODS In this hospital-based cross-sectional study, 1,474 postmenopausal women, admitted with chest pain and referred for invasive coronary angiography were enrolled between April 2013 and October 2018. RESULTS Adjusted odds ratio (95% CI) for obstructive CAD were 1.81 (1.03-3.17) for multigravidity (three or more pregnancies), 1.77 (1.14-2.76) for early menopause (≤40 y old), and 1.72 (1.26-2.35) for short reproductive life span (≤30 y). Each additional year in age at menopause or reproductive life span was associated with a 4% reduction in obstructive CAD risk in postmenopausal women (odds ratio, 0.96; 95% CI, 0.94-0.99; P = 0.011). The other reproductive factors, including parity, age at first birth, spontaneous abortion, induced abortion, stillbirth, hypertensive disorders of pregnancy, gestational diabetes mellitus, and age at menarche, were not correlated with obstructive CAD risk in postmenopausal women. CONCLUSIONS Multigravidity (three or more pregnancies), early menopause, and a shorter reproductive life span were independent risk factors of angiographic obstructive CAD among postmenopausal women, which suggested that pregnancy and ovarian function may be important for the early identification and prevention of increased risk of female angiographic obstructive CAD.

Abstract
Data regarding the potential influence of gender on outcomes of rotational atherectomy (RA) percutaneous coronary intervention (PCI) are scarce and conflicting. Using the Euro4C registry, an international prospective multicentric registry of RA PCI, we evaluated the influence of gender on clinical outcomes of RA PCI. Between October 2016 and July 2018, 966 patients were included. In them, 267 (27.6%) were females. Female patients were older than males (77.7 years old ± 9.8 vs 73.3 ± 9.5 years old respectively, p < 0.001) had a poorer renal function (43,1% of females had a GFR < 60 ml/min:1.73m² vs 30.4% of males, p < 0.001) and were more frequently admitted for an acute coronary syndrome (32.2% vs 22.3% p = 0.002). During RA procedure, women were less likely to be treated by radial approach (65.0% vs 74.4%, p = 0.004). In-hospital major adverse cardiac event rate-defined as cardiovascular death, myocardial infarction, stroke/transient ischemic attack, target lesion revascularization, and coronary artery bypass grafting surgery-was higher in the female group (7.1% vs 3.7%, p = 0.043). However, coronary perforation, dissection, slow/low flow and tamponade did not significantly differ in gender, neither did cardiovascular medications at discharge. At 1 year follow-up, rate of major adverse cardiac event was 18.4% in the female group vs 11.2% in the male group (adjusted Hazard Ratio 1.82 [1.24 to 2.67], p = 0.002). No significant bleeding differences were observed in gender, neither in hospital, nor during follow-up. In conclusion women had worse clinical outcomes following RA PCI during hospitalization and at 1 year follow-up than did men.

Abstract
BACKGROUND Despite cardiac rehabilitation for elder people already showed its usefulness, to date it is still not clear the impact of gender and of psychological constructs in influencing the rehabilitation outcomes. AIM This study aimed at exploring the gender differences of great elders (over 75 years old) in cardiac rehabilitation, with particular attention to the impact of physical and psychological conditions, as depressive symptoms, on long-term post-discharge outcomes. DESIGN A cohort study design was used and a secondary analysis was conducted. SETTING Cardiac rehabilitation unit of a postacute rehabilitation Institute. POPULATION Elderly patients over 75 years old admitted to the cardiac rehabilitation program. METHODS Psychological and functional variables, such as Barthel Index, BMI, quality of life, and depression measured at admission and discharge from CR were matched with mortality information up to 4 years, used as long-term outcomes. RESULTS A total of 523 patients, 228 females and 295 males, with a mean age of 76.27 years±3.46 were progressively enrolled. Barthel index at admission and discharge was higher for males than females, 74.10±17.31 vs. 68.90 SD±16.81 (P<0.001), and 95.45±10.64 vs. 92.95±13.03 (p=0.021), respectively, while the relative change from admission to discharge Δ% of Barthel was higher for females 0.25±0.18 than for males 0.21±0.17 (P<0.05). Compared to males, either at admission or discharge females presented more severe depressive symptoms (5.21±3.46 vs. 3.86±2.79, P<0.001; 4.15±3.21 vs. 2.93±2.45, P<0.001) and a worse quality of life (10.58±2.15 vs. 9.55±2.24, P<0.001; 7.5±1.63 vs. 7.02±1.08, P=0.018). Cox proportional analysis revealed that female gender, depression at discharge, Barthel, and Comorbidity Index were associated with higher hazard and shorter survival time. On the other hand, higher BMI was associated with lower hazard and longer survival time. CONCLUSIONS Elderly women following a CR program present more disability, depression, and a worse QoL than men. Obviously, these characteristics influence the length of hospitalization but with significant improvement. Despite the frail-gender paradox regarding survival, after CR program women have a higher risk of mortality than men. Depression has a significant negative impact on elderly psychophysical health. CLINICAL REHABILITATION IMPACT Gender-specific and individualized rehabilitation programs should be implemented by considering the discussed physical and psychological risk factors. Further insight about gender differences among over 75 elderlies in CR is provided, this knowledge may be useful for clinicians scheduling recovery plans to promote elderlies' psychological and physical health. Psychological interventions should be implemented to relieve the depressive symptoms among elders.

Abstract
BACKGROUND Depressive symptoms (DS) disproportionately affect women with cardiac disease; however, no analyses have been conducted that would allow for focused sex-specific interventions. METHODS Consecutively enrolled women (n = 663) were matched with men postcardiac revascularization at cardiac rehabilitation (CR) entry by primary diagnosis, age, and year of CR entry from database records (2006 to 2017). Multivariate analyses were conducted to determine predictors of DS (≥16 on the Center for Epidemiologic Studies Depression Scale) in all patients and men and women separately. RESULTS In bivariate analysis, women were more likely than men to have DS (30.2% vs 19.3%; P < 0.001) in the matched cohort. A greater proportion of women than men had DS in all 10-year age categories (P < 0.05) except youngest (<50 years; 37% vs 30.4%; P = 0.7) and oldest (≥80; 12.3% vs 10.3%; P = 0.8). DS peaked in women aged 50 to 59 (42.5%) and men <50 years (30.4%). In all patients, independent predictors of DS were younger age, lower cardiorespiratory fitness (VO2peak), being unemployed, greater comorbidities, smoking, anxiolytics, antidepressants, not being married, but not sex. Shared predictors in women-only and men-only analyses were younger age, lower VO2peak, antidepressants, and being unemployed. Unique predictors for women were obesity, smoking, and delayed CR entry and, for men, hypertension, myocardial infarction, anxiolytics, and not being married. CONCLUSIONS Despite matching for age and diagnosis, women were more likely to have DS than men. However, sex was not a predictor of DS in multivariate analyses. This suggests that the profile of women predisposes them to greater DS. Obesity, smoking, and greater delayed CR entry were unique correlates for women and targets for intervention.

Abstract
OBJECTIVES This study is to determine the management and clinical outcomes of patients investigated with coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFRCT) according to sex. BACKGROUND Women are underdiagnosed with conventional ischemia testing, have lower rates of obstructive coronary artery disease (CAD) at invasive coronary angiography (ICA), yet higher mortality compared to men. Whether FFRCT improves sex-based patient management decisions compared to CCTA alone is unknown. METHODS Subjects with symptoms and CAD on CCTA were enrolled (2015 to 2017). Demographics, symptom status, CCTA anatomy, coronary volume to myocardial mass ratio (V/M), lowest FFRCT values, and management plans were captured. Endpoints included reclassification rate between CCTA and FFRCT management plans, incidence of ICA demonstrating obstructive CAD (≥50% stenosis) and revascularization rates. RESULTS A total of 4,737 patients (n = 1,603 females, 33.8%) underwent CCTA and FFRCT. Women were older (age 68 ± 10 years vs. 65 ± 10 years; p < 0.0001) with more atypical symptoms (41.5% vs. 33.9%; p < 0.0001). Women had less obstructive CAD (65.4% vs. 74.7%; p < 0.0001) at CCTA, higher FFRCT (0.76 ± 0.10 vs. 0.73 ± 0.10; p < 0.0001), and lower likelihood of positive FFRCT ≤ 0.80 for the same degree stenosis (p < 0.0001). A positive FFRCT ≤0.80 resulted in equal referral to ICA (n = 510 [54.5%] vs. n = 1,249 [56.5%]; p = 0.31), but more nonobstructive CAD (n = 208 [32.1%] vs. n = 354 [24.5%]; p = 0.0003) and less revascularization (n = 294 [31.4%] vs. n = 800 [36.2%]; p < 0.0001) in women, unless the FFRCT was ≤0.75 where revascularization rates were similar (n = 253 [41.9%] vs. n = 715 [46.4%]; p = 0.06). Women have a higher V/M ratio (26.17 ± 7.58 mm3/g vs. 24.76 ± 7.22 mm3/g; p < 0.0001) that is associated with higher FFRCT independent of degree stenosis (p < 0.001). Predictors of revascularization included stenosis severity, FFRCT, symptoms, and V/M ratio (p < 0.001) but not female sex (p = 0.284). CONCLUSIONS FFRCT differs between the sexes, as women have a higher FFRCT for the same degree of stenosis. In FFRCT-positive CAD, women have less obstructive CAD at ICA and less revascularization, which is associated with higher V/M ratio. The findings suggest that CAD and FFRCT variations by sex need specific interpretation as these differences may affect therapeutic decision making and clinical outcomes.

Abstract
AIMS This study evaluates 10-year follow-up data on associated comorbidity, mortality, and pharmacological treatment patterns for men and women with different stages of peripheral arterial disease (PAD) in a population-based setting. METHODS AND RESULTS This was a prospective observational population-based cohort study, based on physical examinations and questionnaires at baseline supplemented with national register data between 2005 and 2015. Subjects were placed in subgroups defined by ankle-brachial index levels and reported symptoms; asymptomatic PAD (APAD), intermittent claudication (IC), severe limb ischaemia (SLI), or references (Ref). Cox proportional hazards regression models were used for analysis with adjustments for sex and baseline age and comorbidity. The cohort consisted of 5080 subjects (45% males). At baseline, APAD, IC, and SLI were prevalent in 559 (11%), 320 (6.3%), and 78 (1.5%) subjects, respectively. A significant increased risk for cardiovascular (CV) death, even when adjusted for age and baseline morbidity, were noted in all PAD stages as compared with reference group with a small difference between APAD and IC, an adjusted hazard ratio 1.80 (confidence interval 1.45-2.22) and 1.95 (1.50-2.53), respectively. Only about 60% of PAD subjects received medical prophylactic treatment as recommended in guidelines. CONCLUSION Peripheral arterial disease subjects had significantly increased CV morbidity and mortality risks, especially males. Asymptomatic PAD subjects confer similar risk for CV events as symptomatic patients. Our findings motivate enhanced preventive efforts of all PAD stages, including in asymptomatic disease.

A Clinical Tool to Identify Candidates for Stress-First Myocardial Perfusion Imaging. JACC Cardiovasc Imaging 2020; 13:2193-2202. [PMID: 32563652 DOI: 10.1016/j.jcmg.2020.03.022] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 03/10/2020] [Accepted: 03/13/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVES This study sought to develop a clinical model that identifies a lower-risk population for coronary artery disease that could benefit from stress-first myocardial perfusion imaging (MPI) protocols and that can be used at point of care to risk stratify patients. BACKGROUND There is an increasing interest in stress-first and stress-only imaging to reduce patient radiation exposure and improve patient workflow and experience. METHODS A secondary analysis was conducted on a single-center cohort of patients undergoing single-photon emission computed tomography (SPECT) and positron emission tomography (PET) studies. Normal MPI was defined by the absence of perfusion abnormalities and other ischemic markers and the presence of normal left ventricular wall motion and left ventricular ejection fraction. A model was derived using a cohort of 18,389 consecutive patients who underwent SPECT and was validated in a separate cohort of patients who underwent SPECT (n = 5,819), 1 internal cohort of patients who underwent PET (n=4,631), and 1 external PET cohort (n = 7,028). RESULTS Final models were made for men and women and consisted of 9 variables including age, smoking, hypertension, diabetes, dyslipidemia, typical angina, prior percutaneous coronary intervention, prior coronary artery bypass graft, and prior myocardial infarction. Patients with a score ≤1 were stratified as low risk. The model was robust with areas under the curve of 0.684 (95% confidence interval [CI]: 0.674 to 0.694) and 0.681 (95% CI: 0.666 to 0.696) in the derivation cohort, 0.745 (95% CI: 0.728 to 0.762) and 0.701 (95% CI: 0.673 to 0.728) in the SPECT validation cohort, 0.672 (95% CI: 0.649 to 0.696) and 0.686 (95% CI: 0.663 to 0.710) in the internal PET validation cohort, and 0.756 (95% CI: 0.740 to 0.772) and 0.737 (95% CI: 0.716 to 0.757) in the external PET validation cohort in men and women, respectively. Men and women who scored ≤1 had negative likelihood ratios of 0.48 and 0.52, respectively. CONCLUSIONS A novel model, based on easily obtained clinical variables, is proposed to identify patients with low probability of having abnormal MPI results. This point-of-care tool may be used to identify a population that might qualify for stress-first MPI protocols.

Abstract
Coronary artery disease (CAD) is a complex disease caused by the combination of environmental and genetic factors. It is one of the leading causes of death and disability in the world. Much research has been focussed on CAD genetic mechanism. In recent years, genome-wide association study (GWAS) has developed rapidly around the world. Medical researchers around the world have successfully discovered a series of CAD genetic susceptibility genes or susceptible loci using medical research strategies, leading CAD research toward a new stage. This paper briefly summarizes the important progress made by GWAS for CAD in the world in recent years, and then analyzes the challenges faced by GWAS at this stage and the development trend of future research, to promote the transformation of genetic research results into clinical practice and provide guidance for further exploration of the genetic mechanism of CAD.

Abstract
Sex differences in coronary artery disease (CAD) are well established, with women presenting with non-obstructive CAD more often than men do. However, recent evidence has identified coronary microvascular dysfunction as the underlying cause for cardiac complaints, yet sex-specific prevalence numbers are inconclusive. This review summarises known sex-specific aspects in the pathophysiology of both macro- and microvascular dysfunction and identifies currently existing knowledge gaps. In addition, this review describes current diagnostic approaches and whether these should take underlying sex differences into account by, for example, using different techniques or cut-off values for women and men. Future research into both innovation of imaging techniques and perfusion-related sex differences is needed to fill evidence gaps and enable the implementation of the available knowledge in daily clinical practice.

Abstract
BACKGROUND Exercise-based cardiac rehabilitation has a class 1A recommendation in coronary artery disease and heart failure based on its beneficial effects on mortality, morbidity and quality of life. However, the inter-individual response to exercise training is highly variable and influenced by both training and patient characteristics. Notably, men and women display a different training response, even when accounting for age, height and lean muscle mass. Most studies investigating exercise effects on various physiological outcomes focus on male patients. Because women are understudied, the scientific evidence for tailored exercise prescription in women is still limited. METHODS This narrative review summarises: (a) the underlying physiological determinants of the response to exercise training in women with cardiovascular disease, in which women rely more on fat than on carbohydrate oxidation during exercise, have lower aerobic capacities and smaller increases in cardiac function during exercise; (b) the benefits and barriers of exercise in women, in whom improving cardiometabolic risk and quality of life is weighed against socioeconomic and psychological needs; and (c) the relevance of different clinical endpoints in exercise trials such as maximum oxygen uptake, morbidity, mortality, training characteristics, quality of life and metabolic or vascular endpoints. RESULTS Finally, we provide a perspective on how to improve referral, enrolment and adherence to exercise training in women, with structured approaches to inform the referring physician as well as the patient, and offering more flexible, gender-tailored or tele/smartphone-based programmes while addressing the socioeconomic and psychological needs of the patients. This may ultimately improve the admission, adherence and outcome of exercise-based cardiac rehabilitation in women.

Abstract
New knowledge about male-female differences in pathophysiology, diagnosis, and treatment is shifting the practice of medicine from a one-size-fits all approach to a more individualized process that considers sex-specific interventions at the point of care. In this article, we review how clinical practice guideline committees can incorporate a structured framework to determine whether sex-specific assessments of the quality of the evidence or the particular recommendations should be made. The process can be operationalized by societies who author clinical practice guidelines by developing formal policies to approach biological sex in a systematic way, and by ensuring that writing committees include an individual who will champion the formal appraisal of the literature for associations between sex and the outcomes of interest. Ongoing challenges are discussed, and solutions are provided for how to disaggregate the evidence, how to assess bias, how to improve search strategies, and what to do when the data are insufficient to make sex-specific recommendations. Application of sex-specific recommendations will involve routinely asking whether the presentation, diagnostic workup, or management might change for each patient if they were the opposite sex.
