RESUMO
BACKGROUND: Sonothrombolysis is a therapeutic application of ultrasound with ultrasound contrast for patients with ST elevation myocardial infarction (STEMI). Recent trials demonstrated that sonothrombolysis, delivered before and after primary percutaneous coronary intervention (pPCI), increases infarct vessel patency, improves microvascular flow, reduces infarct size, and improves ejection fraction. However, it is unclear whether pre-pPCI sonothrombolysis is essential for therapeutic benefit. We designed a parallel 3-arm sham-controlled randomized controlled trial to address this. METHODS: Patients presenting with first STEMI undergoing pPCI within 6 hours of symptom onset were randomized 1:1:1 into 3 arms: sonothrombolysis pre-/post-pPCI (group 1), sham pre- sonothrombolysis post-pPCI (group 2), and sham pre-/post-pPCI (group 3). Our primary end point was infarct size (percentage of left ventricular mass) assessed by cardiac magnetic resonance imaging at day 4 ± 2. Secondary end points included myocardial salvage index (MSI) and echocardiographic parameters at day 4 ± 2 and 6 months. RESULTS: Our trial was ceased early due to the COVID pandemic. From 122 patients screened between September 2020 and June 2021, 51 patients (age 60, male 82%) were included postrandomization. Median sonothrombolysis took 5 minutes pre-pPCI and 15 minutes post-, without significant door-to-balloon delay. There was a trend toward reduction in median infarct size between group 1 (8% [interquartile range, 4,11]), group 2 (11% [7, 19]), or group 3 (15% [9, 22]). Similarly there was a trend toward improved MSI in group 1 (79% [64, 85]) compared to groups 2 (51% [45, 70]) and 3 (48% [37, 73]) No major adverse cardiac events occurred during hospitalization. CONCLUSIONS: Pre-pPCI sonothrombolysis may be key to improving MSI in STEMI. Multicenter trials and health economic analyses are required before clinical translation.
RESUMO
Cardiovascular disease (CVD) remains the leading cause of death globally. Although the burden of CVD risk factors tends to be lower in women, they remain at higher risk of developing complications when affected by these risk factors. There is still a lack of awareness surrounding CVD in women, both from a patient's and a clinician's perspective, especially among visible minorities. However, women who are informed about their heart health and who engage in decision-making with their healthcare providers are more likely to modify their lifestyle, and improve their CVD risk. A patient-centered care approach benefits patients' physical and mental health, and is now considered gold-standard for efficient patient care. Engaging women in their heart health will contribute in closing the gap of healthcare disparities between men and women, arising from sociocultural, socioeconomic, and political factors. This comprehensive review of the literature discusses the importance of engaging women in decision-making surrounding their heart health and offers tools for an effective and culturally sensitive patient-provider relationship.

This article provides a summary of the clinical spectrum of no obstructive coronary arteries. We describe the pathologies, invasive and noninvasive assessment, and management strategies.
RESUMO
Over half of all patients with angina have no angiographically demonstratable obstructive coronary disease, with a significant proportion of these patients having undiagnosed microvascular dysfunction and/or vasospastic angina. In chronic coronary syndrome, ischemia with non-obstructive coronary artery disease (INOCA) often remains undiagnosed, or uninvestigated. INOCAmay occur due to vasospastic angina and microvascular dysfunction and require invasive assessment in the coronary catheterization lab. To evaluate INOCA coronary flow reserve (CFR) and the index of microcirculatory resistance (IMR) are used to assess microvascular dysfunction before acetylcholine provocation testing for coronary spasm. This review provides an overview of the invasive investigation of INOCA in the coronary catheterization lab for patients with angina to be optimally managed.
RESUMO
BACKGROUND: Sex-based outcome differences for women with ST-segment-elevation myocardial infarction (STEMI) have not been adequately addressed, and the role played by differences in prescription of potent P2Y12 inhibitors (P-P2Y12) is not well defined. This study explores the hypothesis that disparities in P-P2Y12 (prasugrel or ticagrelor) use may play a role in outcome disparities for women with STEMI. METHODS: Data from British Cardiovascular Intervention Society national percutaneous coronary intervention database were analyzed, and 168 818 STEMI patients treated with primary percutaneous coronary intervention from 2010 to 2020 were included. RESULTS: Among the included women (43 131; 25.54%) and men (125 687; 74.45%), P-P2Y12 inhibitors were prescribed less often to women (51.71%) than men (55.18%; P<0.001). Women were more likely to die in hospital than men (adjusted odds ratio, 1.213 [95% CI, 1.141-1.290]). Unadjusted mortality was higher among women treated with clopidogrel (7.57%), than P-P2Y12-treated women (5.39%), men treated with clopidogrel (4.60%), and P-P2Y12-treated men (3.61%; P<0.001). The strongest independent predictor of P-P2Y12 prescription was radial access (adjusted odds ratio, 2.368 [95% CI, 2.312-2.425]), used in 67.93% of women and 74.38% of men (P<0.001). Two risk adjustment models were used. Women were less likely to receive a P-P2Y12 (adjusted odds ratio, 0.957 [95% CI, 0.935-0.979]) with risk adjustment for baseline characteristics alone, when procedural factors including radial access were included in the model differences were not significant (adjusted odds ratio, 1.015 [95% CI, 0.991-1.039]). CONCLUSIONS: Women were less likely to be prescribed prasugrel or ticagrelor, were less likely to have radial access, and had a higher mortality when being treated for STEMI. Improving rates of P-P2Y12 use and radial access may decrease outcome disparities for women with STEMI.

Objective: To investigate the extent to which multivessel disease, incomplete revascularisation and prescribing differences contribute to sex-based outcome disparities in patients with ST-elevation MI (STEMI) and establish whether differences in cardiac death and MI (CDMI) rates persist at long-term follow-up. Methods and results: This observational study evaluates sex-based outcome differences (median follow-up 3.6 years; IQR [2.4-5.4]) in a consecutive cohort of patients (n=2,083) presenting with STEMI undergoing percutaneous coronary intervention). Of the studied patients 20.3% (423/2,083) were women and 38.3% (810/2,083) had multivessel disease (MVD). Incomplete revascularisation was common. The median residual SYNTAX score (rSS) was 5.0 (IQR [0-9]) in women and 5.0 (IQR [1-11]) in men (p=0.369), and in patients with MVD it was 9 (IQR [6-17]) in women and 10 (IQR [6-15]) in men (p=0.838). The primary endpoint CDMI occurred in 20.3% of women (86/423) and in 13.2% of men (219/1,660) (p=0.028). Differences persisted following multivariable risk adjustment: female sex was independently associated with CDMI (aHR 1.33; IQR [1.02-1.74]). Women with MVD had CDMI more often than all other groups (p<0.001 for all). Significant sex-based prescribing differences were evident: women were less likely to receive guideline-recommended potent P2Y12 inhibitors than men (31% versus 43%; p=0.012), and differences were particularly evident in patients with MVD (25% in women versus 45% in men, p=0.011). Conclusion: Sex-based differences in STEMI patient outcome persist at long-term follow-up. Poor outcomes were disproportionately found in women with MVD and those with rSS>8. Observed differences in P2Y12 prescribing practices may contribute to poor outcomes for women with MVD and incomplete revascularisation.
RESUMO
BACKGROUND: Worldwide, the cardiology profession has an under-representation of women. We assessed medical students' perceptions of cardiology as a career choice with the aim of identifying barriers to gender diversity. METHOD: An anonymous survey was distributed to medical students studying at three Australian medical universities. Questions pertained to demographics, year and stage of medical training, desire to pursue cardiology, and perceived barriers to a cardiology career. Results were analysed according to identified gender and desire to pursue or not pursue a cardiology career. Multivariable logistic regression evaluated for independent associations. The primary outcome were barriers identified to pursuing a career in cardiology. RESULTS: From 127 medical student respondents (86.6% female, mean age 25.9±4.8 years), 37.0% stated they wanted to pursue a career in cardiology (39.1% of women versus 23.5% of men, p=0.54). The top four perceived barriers to a cardiology career included: poor work-life balance (92/127, 72.4%), physician training process (63/127, 49.6%), on-call requirements (50/127, 39.4%) and lack of flexibility (49/127, 38.6%), with no gender differences. Women were more likely to report gender-related barriers (37.3% versus 5.9%, p=0.01) and less likely to identify procedural aspects as a barrier (5.5% women versus 29.4% men, p=0.001). Students in their pre-clinical years were more likely to want a career in cardiology (odds ratio 3.0, 95% confidence interval 1.2-7.7, p=0.02). CONCLUSIONS: A high proportion of female and male medical students want to pursue a career in cardiology with both genders identifying major barriers of poor work-life balance, lack of flexibility, on-call requirements and the training process.

AIMS: Pharmaco-invasive percutaneous coronary intervention (PI-PCI) is recommended for patients with ST-elevation myocardial infarction (STEMI)who are unable to undergo timely primary PCI (pPCI). The present study examined late outcomes after PI-PCI (successful reperfusion followed by scheduled PCI or failed reperfusion and rescue PCI)compared with timely and late pPCI (>120 min from first medical contact). METHODS AND RESULTS: All patients with STEMI presenting within 12 h of symptom onset, who underwent PCI during their initial hospitalization at Liverpool Hospital (Sydney), from October 2003 to March 2014, were included. Amongst 2091 STEMI patients (80% male), 1077 (52%)underwent pPCI (68% timely, 32% late), and 1014 (48%)received PI-PCI (33% rescue, 67% scheduled). Mortality at 3 years was 11.1% after pPCI (6.7% timely, 20.2% late) and 6.2% after PI-PCI (9.4% rescue, 4.8% scheduled); P < 0.01. After propensity matching, the adjusted mortality hazard ratio (HR) for timely pPCI compared with scheduled PCI was 0.9 (95% CIs 0.4-2.0) and compared with rescue PCI was 0.5 (95% CIs 0.2-0.9). The adjusted mortality HR for late pPCI, compared with scheduled PCI was 2.2 (95% CIs 1.2-3.1)and compared with rescue PCI, it was 1.5 (95% CIs 0.7-2.0). CONCLUSION: Patients who underwent late pPCI had higher mortality rates than those undergoing a pharmaco-invasive strategy. Despite rescue PCI being required in a third of patients, a pharmaco-invasive approach should be considered when delays to PCI are anticipated, as it achieves better outcomes than late pPCI.

The European Association of Percutaneous Cardiovascular Interventions (EAPCI), the European Heart Rhythm Association (EHRA), the European Association of Cardiovascular Imaging (EACVI), the European Society of Cardiology (ESC) Regulatory Affairs Committee and Women as One support continuous review and improvement, not only in the practice of assuring patients a high quality of care but also in providing health professionals with support documents to help them in their career and enhance gender equity. Recent surveys have revealed that radiation exposure is commonly reported as the primary barrier for women pursuing a career in interventional cardiology or cardiac electrophysiology (EP). The fear of foetal exposure to radiation during pregnancy may lead to a prolonged interruption in their career. Accordingly, this joint statement aims to provide a clear statement on radiation risk and the existing data on the experience of radiation-exposed cardiologists who continue to work in catheterisation laboratories (cath labs) throughout their pregnancies. In order to reduce the barrier preventing women from accessing these careers, increased knowledge in the community is warranted. Finally, by going beyond simple observations and review of the literature, our document suggests proposals for improving workplace safety and for encouraging equity.

Decades of research demonstrate the value of workplace diversity. Reports from individual countries show that women are underrepresented in internal medicine workforces. However, large pooled international studies are not available. This study investigates the current representation of women in the internal medicine workforce internationally and identifies specialties in which underrepresentation is evident. Peer-reviewed studies, government reports, and medical association reports were used to determine proportions of specialists and doctors training in internal medical specialties and in comparator surgical specialties. Data were available from Australia, Canada, England, New Zealand, the United States, Wales, Scotland, and Northern Ireland. A total of 380,263 doctors were studied, including 268,822 practicing specialist physicians (also known as attendings or consultants) and 53,226 doctors in internal medicine specialty training programs (also known as residents, fellows, advanced trainees, or specialist registrar trainees). Among practicing physician specialists, the rate of representation of women was 35% (95,195/268,822, p <0.001). Among trainees, the rate of representation of women was 43% (22,728/53,226, p <0.001). Among physician specialties evaluated, cardiology (15%, 4,152 of 27,328), gastroenterology (20%, 3,765 of 18,893), and respiratory/critical care (24%, 5,255 of 21,870) had the lowest representations of women compared with men (p <0.001 for all). Cardiology and particularly the subspecialty of interventional cardiology were clear outliers as the internal medicine specialties with the lowest representation of women at practicing specialist and trainee levels. In conclusion, this study is the largest international study of women in internal medicine specialties. It found that cardiology, gastroenterology, and respiratory/critical care specialties have the most substantial underrepresentation of women. These data are a global call to action to establish more successful strategies to provide a diverse and representative cardiology workforce.

INTRODUCTION: Spontaneous coronary artery dissection (SCAD) is an under-recognised cause of acute coronary syndrome (ACS) with a strong female predominance. There are currently limited prospective studies and no randomised controlled trials that inform on SCAD's best clinical care. Little is also known about predictors of acute SCAD deterioration or recurrence. We describe the study design of a multi-centre prospective and historical cohort study recruiting patients with SCAD across 15-20 sites in Australia/New Zealand (NZ). The primary aim is to describe the clinical presentation, management and outcomes along with predictors of acute deterioration and recurrence in a large Australian/NZ SCAD cohort, with international data pooling. METHODS AND ANALYSIS: Consented patients diagnosed with SCAD during a hospital admission for an ACS will be prospectively followed at 30 days then yearly, for up to 5 years. Each recruiting site will also retrospectively identify historical cases of SCAD from the proceeding 10 years, with a waiver of consent. For historical cases, data will be collected in a de-identified manner with date of last follow-up or death obtained from the medical records. All cases undergo core laboratory adjudication of coronary angiography and any accompanying imaging to confirm SCAD diagnosis. The primary endpoint will be occurrence of major adverse cardiovascular events; a composite of all-cause mortality, recurrent myocardial infarction (including SCAD recurrence), stroke/transient ischaemic attack, heart failure, cardiogenic shock, cardiac arrest/ventricular arrhythmia, heart transplantation and, repeat/unplanned revascularisation. Secondary endpoints will include each individual primary outcome as well as acute SCAD extension and quality of life/Seattle Angina Score in prospectively recruited participants. Endpoints will be assessed at the end of the hospital admission and at 30-days, 1 year, and median long-term follow-up. ETHICS: Multicentre ethics approval has been granted from the Western Sydney Local Health District Human Research Ethics Committee (2021/ETH00040). DISSEMINATION OF RESULTS: The analysed results will be published in peer-reviewed journals on completion of the historical data collection and then on completion of the prospective data collection. REGISTRATION DETAILS: The ANZ-SCAD registry has been prospectively registered with the Australia and New Zealand Clinical Trials Registry (ACTRN12621000824864).

BACKGROUND: Specialty training in cardiovascular diseases is consistently perceived to have adverse job conditions and interfere with family life. There is a dearth of universal workforce support for trainees who become parents during training. OBJECTIVES: This study sought to identify parental policies across cardiovascular training programs internationally. METHODS: An Internet-based international survey study available from August 2020 to October 2020 was sent via social media. The survey was administered 1 time and anonymously. Participants shared experiences regarding parental benefits/policies and perception of barriers for trainees. Participants were divided into 3 groups: training program directors, trainees pregnant during cardiology fellowship, and trainees not pregnant during training. RESULTS: A total of 417 replies were received from physicians, including 47 responses (11.3%) from training program directors, 146 responses (35%) from current or former trainees pregnant during cardiology training, and 224 responses (53.7%) from current or former trainees that were not pregnant during cardiology training. Among trainees, 280 (67.1%) were parents during training. Family benefits and policies were not uniformly available across institutions, and knowledge regarding the existence of such policies was low. Average parental leave ranged from 1 to 2 months in the United States compared with >4 months outside the United States, and in all countries, paternity leave was uncommon (only 11 participants [2.6%]). Coverage during family leave was primarily provided by peers (n = 184 [44.1%]), and 168 (91.3%) were without additional monetary or time compensation. CONCLUSIONS: This is the first international survey evaluating and comparing parental benefits and policies among cardiovascular training programs. There is great variability among institutions, highlighting disparities in real-world experiences.

The challenges to academic and professional development and career advancement of women in cardiology (WIC), imposed by the pandemic, not only impinge the female cardiologists' "leaky pipeline" but also make the "leakiness" more obvious. This consensus document aims to highlight the pandemic challenges WIC face, raise awareness of the gender equity gap, and propose mitigating actionable solutions derived from the data and experiences of an international group of female cardiovascular clinicians and researchers. This changing landscape has led to the need for highly specialized cardiologists who may have additional training in critical care, imaging, advanced heart failure, or interventional cardiology. Although women account for most medical school graduates, the number of WIC, particularly in mentioned sub-specialties, remains low. Moreover, women have been more affected by systemic issues within these challenging work environments, limiting their professional progression, career advancement, and economic potential. Therefore, it is imperative that tangible action points be noted and undertaken to ensure the representation of women in leadership, advocacy, and decision-making, and increase diversity in academia. Strategies to mitigate the negative impacts of the pandemic need to be taken during this COVID-19 pandemic to ensure WIC have a place in the field of Cardiology.

BACKGROUND: Countries who suffered large COVID-19 outbreaks reported a decrease in acute coronary syndrome (ACS) presentations and percutaneous coronary intervention (PCI). The impact of the pandemic in countries like Australia, with relatively small outbreaks yet significant social restrictions, is relatively unknown. There is also limited and conflicting data regarding the impact on clinical outcomes, symptom-to-door time (STDT) and door-to-balloon time (DTBT). METHODS: Consecutive ACS patients treated with PCI were prospectively recruited from a tertiary hospital network in Melbourne, Australia. The pre-pandemic period (11 March 2019-10 March 2020) was compared to the pandemic period (11 March 2020-10 May 2020) using an interrupted time series analysis with a primary endpoint of number PCI-treated ACS per day. Secondary endpoints included STDT, DTBT, total mortality and major adverse cardiac events (MACE). RESULTS: A total 984 ACS patients (14.8% during the pandemic period) received PCI. Mean number of PCI-treated ACS per day did not differ between the two periods (2.3 vs 2.4, p=0.61) with no difference in STDT [+51.3 mins, 95% confidence interval (CI) -52.4 to 154.9, p=0.33], 30-day mortality (5% vs 5.3%, p=0.86) or MACE (5.2% vs 6.1%, p=0.68). DTBT was significantly longer during the pandemic versus the pre-pandemic period (+18.1 mins, 95% CI 1.6-34.5, p=0.03) and improved with time (slope estimate: -0.76, 95% CI -1.62 to 0.10). CONCLUSIONS: Despite significant social restrictions imposed in Melbourne, numbers of ACS treated with PCI and 30-day outcomes were similar to pre-pandemic times. DTBT was significantly longer during the COVID-19 pandemic period, likely reflecting infection control measures, which reassuringly improved with time.

Women are under-represented among transcatheter aortic valve replacement (TAVR) and transcatheter mitral valve repair (TMVr) operators. This review assesses the representation of women as patients and as proceduralists and trial authors in major structural interventions. Women are under-represented as proceduralists in structural interventions: only 2% of TAVR operators and 1% of TMVr operators are women. Only 1.5% of authors in landmark clinical TAVR and TMVr trials are interventional cardiologists who are women (4/260). Significant under-representation and under-enrolment of women in landmark TAVR trials is evident: the calculated participation-to-prevalence ratio (PPR) is 0.73, and in TMVr trials, the PPR is 0.69. Under-representation of women is also evident in registry data (PPR = 0.84 for TAVR registries and for TMVr registries). In structural interventional cardiology, women are under-represented as proceduralists, trial participants and patients. This under-representation has the potential to affect the recruitment of women to randomised trials, subsequent guideline recommendations, selection for treatment, patient outcomes and sex-specific data analysis.
RESUMO
This review evaluates published data regarding outcomes for women with ACS undergoing PCI. Data is discussed from a patient centred perspective and timeline, beginning with sex-based differences in perception of risk, time to presentation, time to treatment, access to angiography, access to angioplasty, the impact of incomplete revascularization, prescribing practices, under-representation of women in randomized controlled trials and in cardiology physician workforces. The objective of the review is to identify factors contributing to outcome disparities for women with ACS, and to discuss potential solutions to close this outcome gap.
