Abstract
BACKGROUND Left ventricular (LV) dysfunction and ischaemic heart disease (IHD) are common among women. However, women tend to present later and are less likely to receive guideline-directed medical therapy (GDMT) compared with men. METHODS We analysed prospectively collected data (2005-2018) from a multicentre registry on GDMT 30 days after percutaneous coronary intervention in 13,015 patients with LV ejection fraction <50%. Guideline-directed medical therapy was defined as beta blocker, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker±mineralocorticoid receptor antagonist. Long-term mortality was determined by linkage with the Australian National Death Index. RESULTS Women represented 20% (2,634) of the total cohort. Mean age was 65±12 years. Women were on average >5 years, with higher body mass index and higher rates of hypertension, diabetes, renal dysfunction, prior stroke, and rheumatoid arthritis. Guideline-directed medical therapy was similar between sexes (73% vs 72%; p=0.58), although women were less likely to be on an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (80% vs 82%; p=0.02). Women were less likely to be on statin therapy (p<0.001) or a second antiplatelet agent (p=0.007). Women had higher unadjusted long-term mortality (25% vs 19%; p<0.001); however, there were no differences in long-term mortality between sexes on adjusted analysis (hazard ratio 0.99; 95% confidence interval 0.87-1.14; p=0.94). CONCLUSIONS Rates of GDMT for LV dysfunction were high and similar between sexes; however, women were less likely to be on appropriate IHD secondary prevention. The increased unadjusted long-term mortality in women was attenuated in adjusted analysis, which highlights the need for optimisation of baseline risk to improve long-term outcomes of women with IHD and comorbid LV dysfunction.

Abstract
AIMS Increasing transcatheter aortic valve implantation (TAVI) rates have resulted in prolonged waiting times. These have been associated with heart failure hospitalizations (HFH) and mortality yet sex differences have not yet been reported. METHODS AND RESULTS All patients who underwent TAVI for severe aortic stenosis at a tertiary referral hospital in Australia were prospectively included. Total waiting time was divided into 'work-up' waiting time (period from referral date until heart team approval) and, 'procedural' waiting time (period from heart team approval until procedure date). Patients were analysed according to sex. Cohorts were matched to correct for differences in baseline and procedural variables. The primary endpoints were waiting times. Secondary outcomes included a composite of 30-day mortality and HFH, quality of life, and mobility. A total of 407 patients (42% women) were included. After matching of the two cohorts (345 patients), women had significantly longer total waiting times than men: median 156 [interquartile range (IQR) 114-220] days in women vs. 147 [IQR 92-204] days in men (P = 0.037) including longer work-up (83 [IQR 50-128] vs. 71 [IQR 36-119], P = 0.15) and procedural waiting times (65 [IQR 44-100] vs. 58 [IQR 30-93], P = 0.042). Increasing waiting times were associated with higher 30-day mortality and HFH (P = 0.01 for work-up waiting time, P = 0.02 for procedural waiting time) and decreased 30-day mobility (P = 0.044 for procedural waiting time) in women, but not in men. CONCLUSION TAVI waiting times are significantly longer in women compared to men and are associated with increased mortality and HFH and reduced mobility at 30-days.

Abstract
BACKGROUND Recent US guidelines recommend lower blood pressure (BP) targets in hypertension, but aggressive lowering of diastolic BP (DBP) can occur at the expense of myocardial perfusion, particularly in the presence of coronary artery disease. We sought to establish the long-term impact of low DBP on mortality among patients undergoing percutaneous coronary intervention with well-controlled systolic BP. METHODS We analyzed data from 12 965 patients undergoing percutaneous coronary intervention between 2009 and 2018 from the Melbourne Interventional Group registry who had a preprocedural systolic BP of ≤140 mm Hg. Patients with ST-elevation myocardial infarction, cardiogenic shock, and out-of-hospital arrest were excluded. Patients were stratified into 5 groups according to preprocedural DBP: <50, 50 to 59, 60 to 69, 70 to 79, and ≥80 mm Hg. The primary outcome was long-term, all-cause mortality. Mortality data were derived from the Australian National Death Index. RESULTS Patients with DBP<50 mm Hg were older with higher rates of diabetes, renal impairment, prior myocardial infarction, left ventricular dysfunction, peripheral and cerebrovascular disease (all P<0.001). Patients with DBP<50 mm Hg had higher 30-day (2.5% versus 0.7% for the other 4 quintiles; P<0.0001) and long-term mortality (median, 3.6 years; follow-up, 29% versus 11%; P<0.0001). Cox-regression analysis revealed that DBP<50 mm Hg was an independent predictor of long-term mortality (hazard ratio [HR], 1.55 [95% CI, 1.20-2.00]; P=0.001). CONCLUSIONS In patients with well-controlled systolic BP undergoing percutaneous coronary intervention, low DBP (<50 mm Hg) is an independent predictor of long-term mortality.

Abstract
Patients at a low risk of coronary artery disease (CAD) could be triaged to noninvasive coronary computed tomography angiogram instead of invasive coronary angiography, reducing health care costs and patient morbidity. Therefore, we aimed to develop a CAD risk prediction score to identify those who underwent transcatheter aortic valve implantation (TAVI) at a low risk of CAD. We enrolled 1,782 patients who underwent TAVI and randomized the patients to the derivation or validation cohort 2:1. The aortic stenosis-CAD (AS-CAD) score was developed using logistic regression, followed by separation into low- (score 0 to 5), intermediate- (6 to 10), or high-risk (>11) categories. The AS-CAD was validated initially through the k-fold cross-validation, followed by a separately held validation cohort. The average age of the cohort was 82 ± 7 years, and 41% (730 of 1,782) were female; 35% (630) had CAD. The male sex, previous percutaneous coronary intervention, stroke, peripheral arterial disease, diabetes, smoking status, left ventricular ejection fraction <50%, and right ventricular systolic pressure >35 mm Hg were all associated with an increased risk of CAD and were included in the final AS-CAD model (all p <0.03). Within the validation cohort, the AS-CAD score stratified those into low, intermediate, and high risk of CAD (p <0.001). Discrimination was good within the internal validation cohort, with a c-statistic of 0.79 (95% confidence interval 0.74 to 0.84), with similar power obtained using k-fold cross-validation (c-statistic 0.74 [95% confidence interval 0.70 to 0.77]). In conclusion, The AS-CAD score robustly identified those at a low risk of CAD in patients with severe AS. The use of AS-CAD in practice could avoid potential complications of invasive coronary angiogram by triaging low-risk patients to noninvasive coronary assessment using existing computed tomography data.

Abstract
Myocardial infarction complicated by cardiogenic shock (MI-CS) has a poor prognosis, even with early revascularization. Previously, intra-aortic balloon pump (IABP) use was thought to improve outcomes, but the IABP-SHOCK-II (Intra-aortic Balloon Pump in Cardiogenic Shock-II study) trial found no survival benefit. We aimed to determine the trends in IABP use in patients who underwent percutaneous intervention over time. Data were taken from patients in the Melbourne Interventional Group registry (2005 to 2018) with MI-CS who underwent percutaneous intervention. The primary outcome was the trend in IABP use over time. The secondary outcomes included 30-day mortality and major adverse cardiovascular and cerebrovascular events (MACCEs). Of the 1,110 patients with MI-CS, IABP was used in 478 patients (43%). IABP was used more in patients with left main/left anterior descending culprit lesions (62% vs 46%), lower ejection fraction (<35%; 18% vs 11%), and preprocedural inotrope use (81% vs 73%, all p <0.05). IABP use was associated with higher bleeding (18% vs 13%) and 30-day MACCE (58% vs 51%, both p <0.05). The rate of MI-CS per year increased over time; however, after 2012, there was a decrease in IABP use (p <0.001). IABP use was a predictor of 30-day MACCE (odds ratio 1.6, 95% confidence interval 1.18 to 2.29, p = 0.003). However, IABP was not associated with in-hospital, 30-day, or long-term mortality (45% vs 47%, p = 0.44; 46% vs 50%, p = 0.25; 60% vs 62%, p = 0.39). In conclusion, IABP was not associated with reduced short- or long-term mortality and was associated with increased short-term adverse events. IABP use is decreasing but is predominately used in sicker patients with greater myocardium at risk.

Abstract
AIMS To evaluate the long-term incidence of structural valve deterioration (SVD) in patients who underwent transcatheter aortic valve implantation (TAVI). METHOD AND RESULTS Between 2008 and 2018, 693 underwent TAVI at two centres. Four hundred and twenty-one (421) patients (mean age 83.6±6.0 yrs) survived for ≥2 years post TAVI and had at least two consecutive transthoracic echocardiographies (TTEs) with the latest TTE no less than 2 years after TAVI, and were therefore included in the analysis for SVD. Median follow-up was 4.7 (3.6-6.0) years and median echocardiography follow-up 3 (3.0-4.0) years. All-cause mortality was 30.9% (130) with a median time to death of 4.1 (3.0-5.6) years. The cumulative incidence of SVD increased from 1.7% (95% CI, 0.4-2.9) at 3 years to 3.5% (95% CI, 1.5-5.8) at 5 years and 4.7% (95% CI, 1.6-7.9) at 10 years. The overall median time to SVD was 3 (2-4) years. Twelve (12) patients demonstrated SVD stage 2, and 1 patient stage 3. No SVD required re-intervention. All other patients showed no significant changes in valve parameters over time. CONCLUSIONS Structural valve deterioration is an uncommon event, occurring in 5% over a total follow-up of 10 years. Most patients show stable valve parameters. However, the analysis is limited by the loss of follow-up (owing to patient mortality), which renders extrapolation of the data to a younger patient population difficult.

Abstract
BACKGROUND AND HYPOTHESIS Two cohorts face high mortality after ST-elevation myocardial infarction (STEMI): females and patients with in-hospital STEMI. The aim of this study was to evaluate sex differences in ischemic times and outcomes of in-hospital STEMI patients. METHODS Consecutive STEMI patients treated with percutaneous coronary intervention (PCI) were prospectively recruited from 30 hospitals into the Victorian Cardiac Outcomes Registry (2013-2018). Sex discrepancies within in-hospital STEMIs were compared with out-of-hospital STEMIs. The primary endpoint was 12-month all-cause mortality. Secondary endpoints included symptom-to-device (STD) time and 30-day major adverse cardiovascular events (MACE). To investigate the relationship between sex and 12-month mortality for in-hospital versus out-of-hospital STEMIs, an interaction analysis was included in the multivariable models. RESULTS A total of 7493 STEMI patients underwent PCI of which 494 (6.6%) occurred in-hospital. In-hospital versus out-of-hospital STEMIs comprised 31.9% and 19.9% females, respectively. Female in-hospital STEMIs were older (69.5 vs. 65.9 years, p = .003) with longer adjusted geometric mean STD times (104.6 vs. 94.3 min, p < .001) than men. Female versus male in-hospital STEMIs had no difference in 12-month mortality (27.1% vs. 20.3%, p = .92) and MACE (22.8% vs. 19.3%, p = .87). Female sex was not independently associated with 12-month mortality for in-hospital STEMIs which was consistent across the STEMI cohort (OR: 1.26, 95% CI: 0.94-1.70, p = .13). CONCLUSIONS In-hospital STEMIs are more frequent in females relative to out-of-hospital STEMIs. Despite already being under medical care, females with in-hospital STEMIs experienced a 10-min mean excess in STD time compared with males, after adjustment for confounders. Adjusted 12-month mortality and MACE were similar to males.

Abstract
OBJECTIVES Patients with ST-elevation myocardial infarction (STEMI) that occur while already in hospital ('in-hospital STEMI') face high mortality. However, data about this patient population are scarce. We sought to investigate differences in reperfusion and outcomes of in-hospital versus out-of-hospital STEMI. DESIGN, SETTING AND PARTICIPANTS Consecutive patients with STEMI all treated with percutaneous coronary intervention (PCI) across 30 centres were prospectively recruited into the Victorian Cardiac Outcomes Registry (2013-2018). PRIMARY AND SECONDARY OUTCOMES Patients with in-hospital STEMI were compared with patients with out-of-hospital STEMI with a primary endpoint of 30-day major adverse cardiovascular events (MACE). Secondary endpoints included ischaemic times, all-cause mortality and major bleeding. RESULTS Of 7493 patients with PCI-treated STEMI, 494 (6.6%) occurred in-hospital. Patients with in-hospital STEMI were older (67.1 vs 62.4 years, p<0.001), more often women (32% vs 19.9%, p<0.001), with more comorbidities. Patients with in-hospital STEMI had higher 30-day MACE (20.4% vs 9.8%, p<0.001), mortality (12.1% vs 6.9%, p<0.001) and major bleeding (4.9% vs 2.3%, p<0.001), than patients with out-of-hospital STEMI. According to guideline criteria, patients with in-hospital STEMI achieved symptom-to-device times of ≤70 min and ≤90 min in 29% and 47%, respectively. Patients with out-of-hospital STEMI achieved door-to-device times of ≤90 min in 71%. Occurrence of STEMI while in hospital independently predicted higher MACE (adjusted OR 1.77, 95% CI 1.33 to 2.36, p<0.001) and 12-month mortality (adjusted OR 1.49, 95% CI 1.08 to 2.07, p<0.001). CONCLUSIONS Patients with in-hospital STEMI experience delays to reperfusion with significantly higher MACE and mortality, compared with patients with out-of-hospital STEMI, after adjustment for confounders. Focused strategies are needed to improve recognition and outcomes in this high-risk and understudied population.

Abstract
IMPORTANCE The practice of pretreatment with oral P2Y12 inhibitors in non-ST elevation acute coronary syndromes (NSTEACS) remains common; however, its association with improved cardiovascular outcomes is unclear. OBJECTIVE To assess the association between oral P2Y12 inhibitor pretreatment and cardiovascular and bleeding outcomes in patients with NSTEACS. DATA SOURCES On March 20, 2021, PubMed, MEDLINE, Embase, Scopus, Web of Science, Science Direct, clinicaltrials.gov, and the Cochrane Central Register for Controlled Trials were searched from database inception. STUDY SELECTION Randomized clinical trials of patients with NSTEACS randomized to either oral P2Y12 inhibitor pretreatment (defined as prior to angiography) or no pretreatment (defined as following angiography, once coronary anatomy was known) among patients undergoing an invasive strategy. DATA EXTRACTION AND SYNTHESIS This study followed Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Data on publication year, sample size, clinical characteristics, revascularization strategy, P2Y12 inhibitor type and dosage, time from pretreatment to angiography, and end point data were independently extracted by 2 authors. A random-effects model was used, including stratification by (1) P2Y12 inhibitor type, (2) revascularization strategy, and (3) access site. MAIN OUTCOMES AND MEASURES The primary end point was 30-day major adverse cardiac events (MACEs). Secondary end points were 30-day myocardial infarction (MI) and cardiovascular death. The primary safety end point was 30-day major bleeding (defined according to individual studies). RESULTS A total of 7 trials randomizing 13 226 patients to either pretreatment (6603 patients) or no pretreatment (6623 patients) were included. The mean age of patients was 64 years and 3598 (27.2%) were female individuals. Indication for P2Y12 inhibitors was non-ST elevation myocardial infarction in 7430 patients (61.7%), radial access was used in 4295 (32.6%), and 10 945 (82.8%) underwent percutaneous coronary intervention. Pretreatment was not associated with a reduction in 30-day MACE (odds ratio [OR], 0.95; 95% CI, 0.78-1.15; I2 = 28%), 30-day MI (OR, 0.90; 95% CI, 0.72-1.12; I2 = 19%), or 30-day cardiovascular death (OR, 0.79; 95% CI, 0.49-1.27; I2 = 0%). The risk of 30-day major bleeding was increased among patients who underwent pretreatment (OR, 1.51; 95% CI, 1.16-1.97; I2 = 41%). The number needed to harm to bring about 1 major bleeding event with oral P2Y12 inhibitor pretreatment was 63 patients. CONCLUSIONS AND RELEVANCE In this study, pretreatment with oral P2Y12 inhibitors among patients with NSTEACS prior to angiography, compared with treatment once coronary anatomy is known, was associated with increased bleeding risk and no difference in cardiovascular outcomes. Routine pretreatment with oral P2Y12 inhibitors in patients with NSTEACS receiving an early invasive strategy is not supported by this study.

Abstract
Abstract
Background
In patients with prior CABG requiring subsequent PCI there is uncertainty whether bypass grafts or native coronary arteries should be targeted.
Methods
We analysed data from 2,764 patients with prior CABG in the Melbourne Interventional Group registry (2005–2018), divided into two groups: those undergoing PCI to a native vessel (n=1,928) and those with PCI to a graft vessel (n=836).
Results
Patients with a graft vessel PCI were older, had more high-risk clinical characteristics (prior MI, heart failure, ejection fraction <50%, renal impairment, peripheral and cerebrovascular disease), and high-risk procedural features (ACC/AHA types B2/C lesions). However, patients in the native vessel group were more likely to have PCI to a chronic total occlusion. The majority of graft PCI were to saphenous vein grafts (84%), with 10% to radial and 6% to LIMA/RIMA grafts. Distal embolic protection devices were used in 30% of graft PCI. Patients with graft PCI had higher rates of no reflow (6.3% vs. 1.5%; p<0.001), coronary perforation (p=0.016) and inpatient stent thrombosis (p=0.028). However, 30-day mortality and major adverse cardiovascular and cerebrovascular events (MACCE) were similar. Unadjusted long-term mortality (median follow up 4.8 years) was higher in patients who had undergone a graft PCI (44% vs. 32%, p<0.001), but following Cox proportional hazards modelling, PCI vessel type was not a predictor of long-term mortality (HR 1.13; 95% CI 0.96–1.33, p=0.14).
Conclusions
Early clinical outcomes and risk-adjusted long-term mortality are similar for patients with prior CABG undergoing PCI to a native vessel or a bypass graft.

Abstract
Abstract
Background
Myocardial infarction complicated by cardiogenic shock (MI-CS) has a poor prognosis, even with early revascularisation. Previously, intra-aortic balloon pump (IABP) use was thought to improve outcomes, but the SHOCK-II trial in 2012 found no survival benefit.
Purpose
This study aimed to determine the trends in IABP use in patients with MI-CS undergoing percutaneous intervention (PCI) over time and characteristics associated with use.
Methods
Between 2005–2018, patients presenting with MI-CS that underwent percutaneous coronary intervention (PCI) at a hospital participating in the Melbourne Interventional Group Registry were included. The primary outcome was the trend in IABP use over time. Secondary outcomes included mortality, 30-day MACCE (major adverse cardiovascular and cerebrovascular events) and predictors of outcome, determined via logistic regression.
Results
Of the 1,110 patients identified, IABP was used in 478 (43%). IABP was used more in patients with left main and left anterior descending culprit lesions (62% vs. 46%), lower ejection fraction (<35%; 18% vs. 11%), and pre-procedural inotrope use (81% vs. 73%), all p<0.05. IABP use was associated with higher inpatient bleeding (18% vs. 13%) and 30-day MACCE (58% vs. 51%), both p<0.05. The rate of MI-CS increased over time, but after 2012 there was a decline in IABP use (Figure 1). IABP use was a predictor of 30-day MACCE (OR 1.6, 95% CI 1.18–2.29, p=0.003). However, IABP was not associated with in-hospital, 30-day or long-term mortality (45% vs. 47%, p=0.44; 46% vs. 50%, p=0.25; 60% vs. 62%, p=0.39).
Conclusions
Consistent with the SHOCK II trial, IABP use is not associated with reduced short- or long-term mortality, but in this study was associated with increased short-term adverse events. IABP use is declining, but is still used in sicker patients with greater myocardium at risk, given limited alternatives.

Abstract
Abstract
Background
Home inotropes are utilised in those with end-stage heart failure as a bridge to cardiac transplantation. The use of intravenous dobutamine has been linked to cases of eosinophilic myocardial hypersensitivity (EMH), however, little is known about incidence and predictors.
Purpose
We sought to examine the incidence and possible predictors of eosinophilic myocardial hypersensitivity in a cohort of patients on home inotrope therapy at a cardiac transplant centre.
Methods
Patients enrolled in the home inotrope program with progression to heart transplantation or ventricular assist device (VAD) with available myocardial tissue for histopathology, from January 2000 to May 2020 were included. EMH was defined by a pathologist reporting eosinophilic infiltrate with hypersensitivity on myocardial histopathology.
Results
From a cohort of 74 patients, 58% (43) were on dobutamine and 42% (31) were on milrinone. There were zero cases of EMH in those on milrinone. EMH was identified in 14% (6/43) of patients receiving dobutamine. In the dobutamine cohort, the mean age was 52-±12 years, with 22% being female. Non-ischaemic dilated cardiomyopathy encompassed 62%, the remaining 38% were ischaemic cardiomyopathy. Median dobutamine dose (250 [200–282] mcg/min vs. 225 [200–291] mcg/min) and duration of therapy (41 [23–79] days vs. 53 [24–91] days) were similar between those with and without EMH. Rates of known allergy (27% vs. 33%) and asthma (1 patient in each group) were also similar between those with and without EMH. Those with EMH had a median peak eosinophil count of 0.40×109/L (IQR 0.21–0.66×109/L) compared to a peak of only 0.10×109/L (IQR 0.06–0.29×109/L) in the non-EMH cohort. There was a significant difference in the change in absolute eosinophil count between groups; over the duration of dobutamine therapy the median change in eosinophil count was 0.31×109/L (IQR 0.21–0.59×109/L) in the EMH group compared to 0.03×109/L (IQR 0.00–0.14×109/L) in the non-EMH cohort (p=0.02). Peak C-reactive protein was similar between groups (42±46mg/L vs. 44±45mg/L). Mean left ventricular ejection fraction (LVEF) reduced from 19% (±7%) to 17% (±2%) in those with EMH, while LVEF increased from 20% (±7%) to 22% (±9%) in non-EMH patients (Figure 1), p=NS. Re-presentation with heart failure requiring hospitalisation occurred in 83% in the EMH group compared to only 59% in the non-EMH group (p=0.26). The majority of patients with EMH (83%) required VAD as bridge to transplant, compared to only 41% of non-EMH (p=0.05).
Conclusion(s)
EMH occurred in 14% of patients receiving home dobutamine. Patients who developed EMH were more likely to require escalation in treatment to VAD as a bridge to heart transplant. In patients receiving dobutamine a reduction in LVEF, hospitalisation with decompensated heart failure and rising eosinophil count should prompt physicians to consider EMH.

Abstract
OBJECTIVES To compare short- and long-term outcomes after transcatheter aortic valve implantation (TAVI) in the public and private hospital setting. DESIGN Propensity-matched, retrospective analysis of a prospective registry. SETTING AND PARTICIPANTS Patients with severe aortic stenosis who underwent TAVI at a tertiary public hospital (n=507) and an experienced private hospital (n=436). MAIN OUTCOME MEASURES The primary endpoint was all-cause mortality. RESULTS Patients that underwent TAVI in the public hospital were younger than patients in the private hospital (82±8 years vs 84±6 years, p<0.001), with lower estimated short-term mortality risk (Society of Thoracic Surgeons Predicted Risk of Mortality [STS-PROM] score >4.0%: 43% vs 56%, p<0.001). There was no difference between public and private hospitals in 30-day mortality (1.5% vs 1.2%, p=1.0), and the rate of complications was similar. Long-term survival was similar in propensity-matched public (n=344) and private (n=344) patient cohorts. The 1-year, 2-year, 5-year and 7-year survival rates were 95%, 90%, 67% and 47% in public patients, and 92%, 86%, 67% and 51% in private patients (p=0.94). In multivariable analysis, the hospital setting was not a predictor of mortality. CONCLUSION Despite increased age and predicted mortality in private hospital patients, short- and long-term outcomes after TAVI were comparable between public and private hospital settings. This study demonstrates the feasibility of performing TAVI in a private hospital with a dedicated and experienced team and questions the current restricted access to TAVI in the private sector.

Abstract
Background Women with ST‐segment–elevation myocardial infarction experience delays in reperfusion compared with men with little data on each time component from symptom onset to reperfusion. This study analyzed sex discrepancies in patient delays, prehospital system delays, and hospital delays. Methods and Results Consecutive patients with ST‐segment–elevation myocardial infarction treated with percutaneous coronary intervention across 30 hospitals in the Victorian Cardiac Outcomes Registry (2013–2018) were analyzed. Data from the Ambulance Victoria Data warehouse were used to perform linkage to the Victorian Cardiac Outcomes Registry for all patients transported via emergency medical services (EMS). The primary end point was EMS call‐to‐door time (prehospital system delay). Secondary end points included symptom‐to‐EMS call time (patient delay), door‐to‐device time (hospital delay), 30‐day mortality, major adverse cardiovascular events, and major bleeding. End points were analyzed according to sex and adjusted for age, comorbidities, cardiogenic shock, cardiac arrest, and symptom onset time. A total of 6330 (21% women) patients with ST‐segment–elevation myocardial infarction were transported by EMS. Compared with men, women had longer adjusted geometric mean symptom‐to‐EMS call times (47.0 versus 44.0 minutes; P<0.001), EMS call‐to‐door times (58.1 versus 55.7 minutes; P<0.001), and door‐to‐device times (58.5 versus 54.9 minutes; P=0.006). Compared with men, women had higher 30‐day mortality (odds ratio [OR], 1.38; 95% CI, 1.06–1.79; P=0.02) and major bleeding (OR, 1.54; 95% CI, 1.08–2.20; P=0.02). Conclusions Female patients with ST‐segment–elevation myocardial infarction experienced excess delays in patient delays, prehospital system delays, and hospital delays, even after adjustment for confounders. Prehospital system and hospital delays resulted in an adjusted excess delay of 10 minutes compared with men.

Abstract
BACKGROUND/PURPOSE PPMI and CAD are common in patients undergoing TAVR. Despite several studies evaluating their interaction as well as the influence these factors play on outcomes, there remains no consensus. We sought to evaluate the impact of peri-procedural myocardial injury (PPMI) and incidental coronary artery disease (iCAD) on outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS/MATERIALS We analyzed prospective data from 400 patients undergoing TAVI for severe aortic stenosis between 2008 and 2018 to determine rates of PPMI (troponin 15× the upper limit of normal) and iCAD (≥50% stenosis) and their impact on long-term mortality. RESULTS Mean age was 83 ± 6 years; 45% were female. PPMI was observed in 65% (254/400). On multivariable logistic regression analysis, higher left ventricular ejection fraction (LVEF) (OR 1.04, 95%CI 1.01-1.06, p = 0.002), and first generation valves (OR 3.00, 95%CI 1.75-5.15, p < 0.001) were independently associated with PPMI, while oral anticoagulation was inversely associated (OR 0.48, 95%CI 0.28-0.82, p = 0.007). PPMI was not associated with 30-day, 1-year or long-term mortality. After excluding previous bypass grafting, iCAD was observed in 40% (129/324). In patients with iCAD, PCI was associated with reduced long-term mortality compared to medical management in adjusted analysis (OR 0.37, 95%CI 0.16-0.88, p = 0.03). CONCLUSIONS PPMI and iCAD in patients undergoing TAVR are common. PPMI is associated with older generation valves and higher LVEF rather than traditional cardiovascular risk factors. In our study, PPMI was not associated with long-term mortality. However, in patients with iCAD, PCI was associated with reduced long-term mortality compared to medical management.

Abstract
Abstract
Aims
We sought to investigate if sex disparity exists for secondary prevention pharmacotherapy following acute coronary syndrome (ACS) and impact on long-term clinical outcomes.
Methods and results
We analysed data on medical management 30-day post-percutaneous coronary intervention (PCI) for ACS in 20 976 patients within the multicentre Melbourne Interventional Group registry (2005–2017). Optimal medical therapy (OMT) was defined as five guideline-recommended medications, near-optimal medical therapy (NMT) as four medications, sub-optimal medical therapy (SMT) as ≤3 medications. Overall, 65% of patients received OMT, 27% NMT and 8% SMT. Mean age was 64 ± 12 years; 24% (4931) were female. Women were older (68 ± 12 vs. 62 ± 12 years) and had more comorbidities. Women were less likely to receive OMT (61% vs. 66%) and more likely to receive SMT (10% vs. 8%) compared to men, P < 0.001. On long-term follow-up (median 5 years, interquartile range 2–8 years), women had higher unadjusted mortality (20% vs. 13%, P < 0.001). However, after adjusting for medical therapy and baseline risk, women had lower long-term mortality [hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.79–0.98; P = 0.02]. NMT (HR 1.17, 95% CI 1.05–1.31; P = 0.004) and SMT (HR 1.79, 95% CI 1.55–2.07; P < 0.001) were found to be independent predictors of long-term mortality.
Conclusion
Women are less likely to be prescribed optimal secondary prevention medications following PCI for ACS. Lower adjusted long-term mortality amongst women suggests that as well as baseline differences between gender, optimization of secondary prevention medical therapy amongst women can lead to improved outcomes. This highlights the need to focus on minimizing the gap in secondary prevention pharmacotherapy between sexes following ACS.

Abstract
Transcatheter aortic valve implantation (TAVI) is emerging as the default strategy for older patients with severe, symptomatic, and trileaflet aortic stenosis. Increased body-mass index (BMI) is associated with a protective effect in patients undergoing percutaneous coronary intervention. We assessed whether elevated BMI was associated with a similar association in TAVI. We evaluated prospectively collected data from 634 patients who underwent TAVI at 2 centers from August 2008 to April 2019. Patients were stratified as normal weight (BMI 18.5 to 24.9 kg/m2, n = 214), overweight (25 to 29.9 kg/m2, n = 234), and obese (>30 kg/m2, n = 185). Outcomes were reported according to VARC-2 criteria. Mortality was assessed using Cox proportional hazards regression analysis (median follow-up 2 years). Kaplan-Meier analysis was used to estimate cumulative mortality. Baseline differences were seen in age (85 vs 84 vs 82, p <0.001), STS-PROM score (4.3 vs 3.4 vs 3.6, p <0.001), sex (50% vs 36% vs 55% female, p <0.001), clinical frailty score (p = 0.02), diabetes (21% vs 29% vs 40%, p <0.001), and presence of chronic obstructive pulmonary disease (COPD) (13% vs 13% vs 23%, p = 0.009). On multivariable analysis there was no mortality difference between normal and obese patients (hazard ratio [HR] 0.70, confidence interval [CI] 0.46 to 1.1 p = 0.11), however overweight patients had significantly lower mortality (HR 0.56 CI 0.38 to 0.85, p = 0.006). Variables independently associated with increased mortality were increasing age, male sex, COPD, previous balloon valvuloplasty, and higher STS-PROM. In conclusion, overweight patients have lower long-term mortality when compared with normal weight and obese patients undergoing TAVI.

Abstract
Abstract
Background and purpose
Women at increased surgical risk have been shown to have better outcomes with transcatheter aortic valve implantation (TAVI) as compared to surgical valve replacement (SAVR). With the scope of TAVI moving into low-surgical risk patients we aimed to update the current literature to include the new low-risk randomized controlled trial data in investigating outcomes by sex.
Methods
We systematically searched MedlineOVID, PubMed, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and reference lists for relevant randomised controlled trials (RCTs) comparing TAVI to SAVR published prior to October 7th 2019. Data extraction was performed by two independent authors and included trial design details, baseline characteristics and outcome data stratified by sex. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Quantitative synthesis of pooled data was performed using Mantel-Haenszel fixed or random effects model. Q-statistic and the I2 test were used for assessment of heterogeneity.
Results
Our search yielded eight RCTs included in the final quantitative synthesis. The overall pooled cohort was 8,040, of whom 41.4% were female. Women had significantly lower rates of one-year all-cause mortality and one-year composite endpoint with TAVI as compared to SAVR. The selective mortality benefit with TAVI over SAVR in women did not persist to five-years. At 30-days, women demonstrated lower rates of major bleeding and acute kidney injury following TAVI compared to SAVR. For men, these outcomes were similar regardless of type of intervention. Both sexes were at increased risk of major vascular complications with TAVI as compared to SAVR, however women demonstrated nearly double the odds of major vascular complication with TAVI compared to men.
Conclusion
Our updated meta-analysis demonstrates that at one-year women undergoing TAVI have significantly lower mortality and better safety outcomes compared to those undergoing SAVR. These benefits are not seen in men. In the new low-risk era, these results are ever more important for guiding appropriate patient selection.

Abstract
Abstract
Background
Left ventricular dysfunction and ischaemic heart disease are common amongst women, however, women tend to present later and are less likely to receive guideline-directed medical therapy compared to their male counterparts.
Purpose
To investigate if a sex discrepancy exists for optimal medical therapy (OMT) and long-term mortality in a cohort of patients with known ischaemic heart disease (IHD) and left ventricular dysfunction.
Methods
We analysed prospectively collected data from a multicentre registry database collected between 2005–2018 on pharmacotherapy 30-days post percutaneous coronary intervention (PCI) in 13,015 patients with left ventricular ejection fraction (LVEF) <50%. OMT at 30-days was defined as beta-blocker (BB), angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEi/ARB) ± mineralocorticoid receptor antagonist (MRA). Long-term mortality was determined by linkage with the National Death Index, with median follow up of 4.7 (IQR 2.0–8.6) years.
Results
Mean age was 65±12 years; women represented 20.2% (2,634) of the cohort. Women were on average 5 years older, had higher average BMI, higher rates of hypertension, diabetes, renal dysfunction, prior stroke and rheumatoid arthritis. Men were more likely to have sleep apnoea, be current/ex-smokers and to have had prior myocardial infarction, PCI and bypass surgery. Overall, 72.3% (9,411) of patients were on OMT, which was similar between sexes (72.7% in women vs. 72.2% in men, p=0.58). Rates of BB therapy were similar between sexes (85.2% vs. 84.5%, p=0.38), while women were less likely to be on an ACEi/ARB (80.4% vs. 82.4%, p=0.02) and more likely to be on a MRA (12.1% vs. 10.0%, p=0.003). Amongst those with LVEF ≤35% (n=1,652), BB (88.7% vs. 87.3%, p=0.46), ACEi/ARB (83.3% vs. 82.1%, p=0.59) and MRA use (32.5% vs. 33.3%, p=0.78) was comparable. Aspirin use was similar between sexes (95.3% vs. 95.9%, p=0.12), while women were less likely to be on statin therapy (93.5% vs. 95.3%, p<0.001) and a second antiplatelet agent (94.4% vs. 95.6%, p=0.007). On unadjusted analysis women had significantly higher long-term mortality of 25.4% compared to 19.0% for men (p<0.001). Kaplan-Meier analysis out to 14 years demonstrated that men on OMT have the best long-term survival overall and women on sub-OMT have significantly poorer outcomes compared to men on sub-OMT. However, after adjusting for OMT and other comorbidities there was no difference in long-term mortality between sexes (HR 0.99, 95% CI 0.87–1.14, p=0.94).
Conclusion
From this large multicentre registry, we found similar rates of guideline-directed pharmacotherapy for left ventricular dysfunction between sexes, however women were less likely to be on appropriate IHD secondary prevention. The increased unadjusted long-term mortality amongst women is likely due to differing baseline risk, given that adjusted mortality was similar between sexes.

Abstract
Previous studies indicate that women who underwentwho underwent transcatheter aortic valve implantation (TAVI) have poorer 30-day outcomes compared with men. However, the effect of gender as a prognostic factor for long-term outcomes following TAVI remains unclear. Between 2008 and 2018, all patients (n = 683) who underwent TAVI in 2 centres in Melbourne, Australia were prospectively included in a registry. The primary end-point was long-term mortality. The secondary end points were Valve Academic Research Consortium-2 (VARC-2) in-hospital complications and mortality at 30-days and 1-year. Of 683 patients, 328 (48%) were women. Women had a higher mean STS-PROM score (5.2 ± 3.1 vs 4.6 ± 3.5, p < 0.001) but less co-morbidities than men. Women had a significantly higher in-hospital bleeding rates (3.3% vs 1.0%, Odds Ratio 4.21, 95% confidence interval [CI] 1.16 to15.25, p = 0.027) and higher 30-day mortality (2.4% vs 0.3%, hazard ratio [HR] 8.75, 95% CI 1.09 to 69.6, p = 0.040) than men. Other VARC-2 outcomes were similar between genders. Overall mortality rate was 36% (246) over a median follow up of 2.7 (interquartile rang [IQR] 1.7 to 4.2) years. Median time to death was 5.3 (95% CI 4.7 to 5.7) years. One-year mortality was similar between genders (8.3% vs 7.8%), as was long-term mortality (HR = 0.91, 95% CI 0.71 to 1.17, p = 0.38). On multivariable analysis, female gender was an independent predictor for 1-year mortality (HR = 2.33, 95% CI 1.11 to 4.92, p = 0.026), but not long-term mortality (HR = 0.78, 95% CI 0.54 to 1.14, p = 0.20). In the women only cohort, STS-PROM was the only independent predictor of long-term mortality (HR 1.88, 95% CI 1.42 to 2.48, p < 0.001). In conclusion, women had higher rates of peri-procedural major bleeding and 30-day mortality following TAVI. However, long-term outcomes were similar between genders.

Abstract
Guidelines mandate emergent revascularization in patients presenting with ST-elevation myocardial infarction (STEMI) irrespective of gender. We sought to compare the door-to-balloon times and the impact of timely reperfusion on clinical outcomes in women compared with men presenting with STEMI undergoing primary percutaneous coronary intervention (PPCI). We analyzed data from 6,179 consecutive patients presenting with STEMI undergoing PPCI from the Melbourne Interventional Group registry (2005 to 2017). The primary outcome was long-term mortality. Of the 6,179 patients included 1,258 (20.3%) were female. Female patients were older (69 ± 13 vs 62 ± 12 years; p < 0.001), had more co-morbidities and had longer median symptom-to-balloon times (204 [interquartile range {IQR} 154 to 294] vs 181 [IQR 139 to 258] minutes; p < 0.001) and longer median door-to-balloon times (81 [IQR 55 to 102] vs 75 [IQR 51 to 102)] minutes; p < 0.001), while receiving less drug-eluting stents (39% vs 43%; p = 0.01) and having less radial access for PPCI (15% vs 21%; p < 0.001). Furthermore, female patients received less guideline-directed medical therapy than men with less prescription of aspirin (93.4% vs 95.4%; p = 0.02), statins (96.5% vs 97.6%; p < 0.05), and beta blockers (84.3% vs 89.4%; p < 0.001). Unadjusted in-hospital and 30-day mortality rates were higher in women (8.8% vs 6.2%, 9.8% vs 6.9%; p < 0.001). However, on Cox-proportional hazards modeling, gender was not an independent predictor of long-term mortality (hazards ratio 0.99, 95% confidence interval 0.83 to 1.18; p = 0.92) at a mean follow-up of 4.8 ± 3.5 years. In conclusion, in this large multicenter registry of patients with STEMI, women had longer ischemic times, higher risk profiles, and differing interventional approaches compared with men. Addressing these gender inequalities with early identification of symptoms, adherence to guideline-directed medical therapy, as well as higher rates of radial access and use of drug-eluting stents has the potential to further improve outcomes in women with STEMI.

Abstract
High-order harmonic generation in polyatomic molecules generally involves multiple channels of ionization. Their relative contribution can be strongly influenced by the presence of resonances, whose assignment remains a major challenge for high-harmonic spectroscopy. Here we present a multi-modal approach for the investigation of unaligned polyatomic molecules, using SF6 as an example. We combine methods from extreme-ultraviolet spectroscopy, above-threshold ionization and attosecond metrology. Fragment-resolved above-threshold ionization measurements reveal that strong-field ionization opens at least three channels. A shape resonance in one of them is found to dominate the signal in the 20-26 eV range. This resonance induces a phase jump in the harmonic emission, a switch in the polarization state and different dynamical responses to molecular vibrations. This study demonstrates a method for extending high-harmonic spectroscopy to polyatomic molecules, where complex attosecond dynamics are expected.
