RESUMO
BACKGROUND AND AIM: Risk adjustment following percutaneous coronary intervention (PCI) is vital for clinical quality registries, performance monitoring, and clinical decision-making. There remains significant variation in the accuracy and nature of risk adjustment models utilised in international PCI registries/databases. Therefore, the current systematic review aims to summarise preoperative variables associated with 30-day mortality among patients undergoing PCI, and the other methodologies used in risk adjustments. METHOD: The MEDLINE, EMBASE, CINAHL, and Web of Science databases until October 2022 without any language restriction were systematically searched to identify preoperative independent variables related to 30-day mortality following PCI. Information was systematically summarised in a descriptive manner following the Checklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies checklist. The quality and risk of bias of all included articles were assessed using the Prediction Model Risk Of Bias Assessment Tool. Two independent investigators took part in screening and quality assessment. RESULTS: The search yielded 2,941 studies, of which 42 articles were included in the final assessment. Logistic regression, Cox-proportional hazard model, and machine learning were utilised by 27 (64.3%), 14 (33.3%), and one (2.4%) article, respectively. A total of 74 independent preoperative variables were identified that were significantly associated with 30-day mortality following PCI. Variables that repeatedly used in various models were, but not limited to, age (n=36, 85.7%), renal disease (n=29, 69.0%), diabetes mellitus (n=17, 40.5%), cardiogenic shock (n=14, 33.3%), gender (n=14, 33.3%), ejection fraction (n=13, 30.9%), acute coronary syndrome (n=12, 28.6%), and heart failure (n=10, 23.8%). Nine (9; 21.4%) studies used missing values imputation, and 15 (35.7%) articles reported the model's performance (discrimination) with values ranging from 0.501 (95% confidence interval [CI] 0.472-0.530) to 0.928 (95% CI 0.900-0.956), and four studies (9.5%) validated the model on external/out-of-sample data. CONCLUSIONS: Risk adjustment models need further improvement in their quality through the inclusion of a parsimonious set of clinically relevant variables, appropriately handling missing values and model validation, and utilising machine learning methods.

BACKGROUND: Acute decompensated heart failure (ADHF) is a leading cause of cardiovascular disease hospitalisations associated with significant morbidity and mortality. In hospitals, HF patients are typically managed by cardiology or physician teams, with differences in patient demographics and clinical outcomes. This study utilises contemporary HF registry data to compare patient characteristics and outcomes in those with ADHF admitted into General Medicine and Cardiology units. METHODS: The Victorian Cardiac Outcomes Registry was utilised to identify patients hospitalised with ADHF 30-day period in each of four consecutive years. We compared patient characteristics, pharmacological management and outpatient follow-up of patients admitted to General Medicine and Cardiology units. Primary outcome measures included in-hospital mortality, 30-day readmission, and 30-day mortality. RESULTS: Between 2014 and 2017, a total of 1,253 patients with ADHF admissions were registered, with 53% admitted in General Medicine units and 47% in Cardiology units. General Medicine patients were more likely to be older (82 vs 71 years; p<0.001), female (51% vs 34%; p<0.001), and have higher prevalence of comorbidities and preserved left ventricular function (p<0.001). There were no differences in primary outcome measures between General Medicine and Cardiology in terms of: in-hospital mortality (5.0% vs 3.9%; p=0.35), 30-day readmission (23.4% vs 23.6%; p=0.93), and 30-day mortality (10.0% vs 8.0%; p=0.21). CONCLUSIONS: Hospitalised patients with HF continue to have high mortality and rehospitalisation rates. The choice of treatment by General Medicine or Cardiology units, based on the particular medical profile and individual needs of the patients, provides equivalent outcomes.

BACKGROUND: Clinical outcomes of patients with renal transplant (RT) undergoing percutaneous coronary intervention (PCI) remain poorly elucidated. METHOD: Between 2014 and 2021, data were analysed for the following three groups of patients undergoing PCI enrolled in a multicentre Australian registry: (1) RT recipients (n=226), (2) patients on dialysis (n=992), and (3) chronic kidney disease (CKD) patients (estimated glomerular filtration rate [eGFR], 30â60 mL/min per 1.73 m2) without previous RT (n=15,534). Primary outcome was 30-day major adverse cardiac and cerebrovascular events (MACCEs)-composite of mortality, myocardial infarction, stent thrombosis, target vessel revascularisation, and stroke. RESULTS: RT recipients were younger than dialysis and patients with CKD (61±10 vs 68±12 vs 78±8.2 years, p<0.001). Patients with RT less frequently had severe left ventricular dysfunction compared with dialysis and CKD groups (6.7% vs 14% and 8.5%); however more, often presented with acute coronary syndrome (58% vs 52% and 48%), especially STEMI (all p<0.001). Patients with RT and CKD had lower rates of 30-day MACCE (4.4% and 6.8% vs 11.6%, p<0.001) than the dialysis group. Three-year survival was similar between RT and CKD groups, however was lower in the dialysis group (80% and 83% vs 60%, p<0.001). After adjustment, dialysis was an independent predictor of 30-day MACCE (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.44â2.50, p<0.001), however RT was not (OR 0.91, CI 0.42â1.96, p=0.802). Both RT (hazard ratio [HR] 2.07, CI 1.46â2.95, p<0.001) and dialysis (HR 1.35, CI 1.02â1.80, p=0.036) heightened the hazard of long-term mortality. CONCLUSIONS: RT recipients have more favourable clinical outcomes following PCI compared with patients on dialysis. However, despite having similar short-term outcomes to patients with CKD, the hazard of long-term mortality is significantly greater for RT recipients.

AIM: We aim to describe prevalence of Emergency Medical Service (EMS) use, investigate factors predictive of EMS use, and determine if EMS use predicts treatment delay and mortality in our ST-elevation myocardial infarction (STEMI) cohort. METHOD: We prospectively collected data on 5,602 patients presenting with STEMI for primary percutaneous coronary intervention (PCI) transported to PCI-capable hospitals in Victoria, Australia, from 2013-2018 who were entered into the Victorian Cardiac Outcomes Registry (VCOR). We linked this dataset to the Ambulance Victoria and National Death Index (NDI) datasets. We excluded late presentation, thrombolysed, and in-hospital STEMI, as well as patients presenting with cardiogenic shock and out-of-hospital cardiac arrest. RESULTS: In total, 74% of patients undergoing primary PCI for STEMI used EMS. Older age, female gender, higher socioeconomic status, and a history of prior ischaemic heart disease were independent predictors of using EMS. EMS use was associated with shorter adjusted door-to-balloon (53 vs 72 minutes, p<0.001) and symptom-to-balloon (183 vs 212 minutes, p<0.001) times. Mode of transport was not predictive of 30-day or 12-month mortality. CONCLUSIONS: EMS use in Victoria is relatively high compared with internationally reported data. EMS use reduces treatment delay. Predictors of EMS use in our cohort are consistent with those prevalent in prior literature. Understanding the patients who are less likely to use EMS might inform more targeted education campaigns in the future.

BACKGROUND: Acute coronary syndrome (ACS) admissions and percutaneous coronary intervention (PCI) volume declined during periods of COVID-19 lockdown internationally in 2020. The effect of lockdown on emergency medical service (EMS) utilisation, and PCI volume during the initial phase of the pandemic in Australia has not been well described. METHOD: We analysed data from the Victorian Cardiac Outcomes Registry (VCOR), a state-wide PCI registry, linked with the Ambulance Victoria EMS registry. PCI volume, 30-day major adverse cardiovascular and cerebrovascular events (MACCE; composite of mortality, myocardial infarction, stent thrombosis, unplanned revascularisation, and stroke), and EMS utilisation were compared over four time periods: lockdown (26 Mar 2020-12 May 2020); pre-lockdown (26 Feb 2020-25 Mar 2020); post-lockdown (13 May 2020-10 Jul 2020); and the year prior (26 Mar 2019-12 May 2019). Interrupted time series analysis was performed to assess PCI trends within and between consecutive periods. RESULTS: The EMS utilisation for ACS during lockdown was higher compared with other periods: lockdown 39.4% vs pre-lockdown 29.7%; vs post-lockdown 33.6%; vs year prior 27.1%; all p<0.01. Median daily PCI cases were similar: 31 (IQR 10, 38) during lockdown; 39 (15, 49) pre-lockdown; 39.5 (11, 44) post-lockdown; and, 42 (10, 49) the year prior; all p>0.05. Median door-to-procedure time for ACS indication during lockdown was shorter at 3 hours (1.2, 20.6) vs pre-lockdown 3.9 (1.7, 21); vs post-lockdown 3.5 (1.5, 21.26); and, the year prior 3.5 (1.5, 23.7); all p<0.05. Lockdown period was associated with lower odds for 30-day MACCE compared to pre-lockdown (odds ratio [OR] 0.55 [0.33-0.93]; p=0.026); post-lockdown (OR 0.66; [0.40-1.06]; p=0.087); and the year prior (OR 0.55 [0.33-0.93]; p=0.026). CONCLUSIONS: Contrary to international trends, EMS utilisation for ACS increased during lockdown but PCI volumes remained similar throughout the initial stages of the pandemic in Victoria, with no observed adverse effect on 30-day MACCE during lockdown. These data suggest that the public health response in Victoria was not associated with poorer quality cardiovascular care in patients receiving PCI.

BACKGROUND: An adverse interaction whereby opioids impair and delay the gastrointestinal absorption of oral P2Y12 inhibitors has been established, however the clinical significance of this in acute coronary syndrome (ACS) is uncertain. We sought to characterise the relationship between prehospital opioid dose and clinical outcomes in patients with ACS. METHODS: Patients given opioid treatment by emergency medical services (EMS) with ACS who underwent percutaneous coronary intervention (PCI) between 1 January 2014 and 31 December 2018 were included in this retrospective cohort analysis using data linkage between the Ambulance Victoria, Victorian Cardiac Outcomes Registry and Melbourne Interventional Group databases. Patients with cardiogenic shock, out-of-hospital cardiac arrest and fibrinolysis were excluded. The primary end point was the risk-adjusted odds of 30-day major adverse cardiac events (MACE) between patients who received opioids and those that did not. RESULTS: 10 531 patients were included in the primary analysis. There was no significant difference in 30-day MACE between patients receiving opioids and those who did not after adjusting for key patient and clinical factors. Among patients with ST-elevation myocardial infarction (STEMI), there were significantly more patients with thrombolysis in myocardial infarction (TIMI) 0 or 1 flow pre-PCI in a subset of patients with high opioid dose versus no opioids (56% vs 25%, p<0.001). This remained significant after adjusting for known confounders with a higher predicted probability of TIMI 0/1 flow in the high versus no opioid groups (33% vs 11%, p<0.001). CONCLUSIONS: Opioid use was not associated with 30-day MACE. There were higher rates of TIMI 0/1 flow pre-PCI in patients with STEMI prescribed opioids. Future prospective research is required to verify these findings and investigate alternative analgesia for ischaemic chest pain.

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.

OBJECTIVE: The Asia-Pacific Evaluation of Cardiovascular Therapies (ASPECT) collaboration was established to inform on percutaneous coronary intervention (PCI) in the Asia-Pacific Region. Our aims were to (i) determine the operational requirements to assemble an international individual patient dataset and validate the processes of governance, data quality and data security, and subsequently (ii) describe the characteristics and outcomes for ST-elevation myocardial infarction (STEMI) patients undergoing PCI in the ASPECT registry. METHODS: Seven (7) ASPECT members were approached to provide a harmonised anonymised dataset from their local registry. Patient characteristics were summarised and associations between the characteristics and in-hospital outcomes for STEMI patients were analysed. RESULTS: Six (6) participating sites (86%) provided governance approvals for the collation of individual anonymised patient data from 2015 to 2017. Five (5) sites (83%) provided >90% of agreed data elements and 68% of the collated elements had <10% missingness. From the registry (n=12,620), 84% were male. The mean age was 59.2±12.3 years. The Malaysian cohort had a high prevalence of previous myocardial infarction (34%), almost twice that of any other sites (p<0.001). Adverse in-hospital outcomes were the lowest in Hong Kong whilst in-hospital mortality varied from 2.7% in Vietnam to 7.9% in Singapore. CONCLUSIONS: Governance approvals for the collation of individual patient anonymised data was achieved with a high level of data alignment. Secure data transfer process and repository were established. Patient characteristics and presentation varied significantly across the Asia-Pacific region with this likely to be a major predictor of variations in the clinical outcomes observed across the region.

OBJECTIVES: Patients with stable ischemic heart disease (SIHD) may present with a variety of symptoms including typical angina, angina equivalents such as dyspnea or no symptoms. We sought to determine whether symptom status affects periprocedural safety and long-term mortality in patients undergoing PCI. METHODS: Prospectively enrolled consecutive patients undergoing PCI for SIHD at six hospitals in Australia between 2005 to 2018 as part of the Melbourne Interventional Group registry. Symptom status was recorded at the time of PCI and patients undergoing staged PCI were excluded. RESULTS: Overall, 11,730 patients with SIHD were followed up for a median period of 5 years (maximum 14.0 years, interquartile range 2.2-9.0 years) with 1,317 (11.2%) being asymptomatic. Asymptomatic patients were older, and more likely to be male, have triple-vessel disease, with multiple comorbidities including renal failure, diabetes and heart failure (all P < .01). These patients had significantly higher rates of periprocedural complications and major adverse cardiovascular events at 30-days. Long-term mortality was significantly higher in asymptomatic patients (27.2% vs 18.0%, P < .001). On cox regression for long-term mortality, after adjustment for more important clinical variables, asymptomatic status was an independent predictor (Hazard ratio (HR) 1.39 95% CI 1.16-1.66, P < .001). CONCLUSIONS: In a real-world cohort of patients undergoing revascularization for SIHD, absence of symptoms was associated with higher rates of periprocedural complications and, after adjustment for more important clinical variables, was an independent predictor of long-term mortality. As the primary goal of revascularization in SIHD remains angina relief, the appropriateness of PCI in the absence of symptoms warrants justification.

BACKGROUND: Diabetes mellitus (DM) is a predictor of restenosis and late stent thrombosis (ST) in patients undergoing percutaneous coronary intervention (PCI) with drug-eluting-stents (DES). Real-world data on rates of early ST is lacking. We compared clinical outcomes of patients with and without DM from the Victorian cardiac outcomes registry. METHODS: Consecutive patients undergoing PCI with DES were analyzed with primary outcome being ST at 30-days. Secondary outcomes including major adverse cardiovascular events (MACE) and all-cause mortality. RESULTS: Of 43,209 patients included, 9730 (22.5%) had DM. At 30 days, DM was independently associated with higher rates of early ST (0.7% vs. 0.5%) OR 1.41 (95% confidence interval; 1.05-1.87, p = 0.02), MACE (4.1% vs. 3.5%, p = 0.004) and mortality (1.9% vs. 1.5%, p = 0.01). Increased risk was not simply due to treatment. Patients with DM requiring insulin were equally affected in regard to MACE (4.7% vs. 3.9%, p = 0.069) and mortality (1.9%, vs. 1.8%, p = 0.746). On National Death Index linkage, patients with DM had increased all-cause mortality over five-year follow-up (OR 1.69 CI 1.55-1.83, p = < 0.001). CONCLUSION: In this large real-world-registry, DM was an independent predictor of early ST, MACE and mortality at 30 days. These data suggest additional therapeutic strategies are required to reduce the risk of early complications in patients with DM undergoing PCI with DES.

OBJECTIVES: To examine predictors and outcomes of unsuccessful percutaneous coronary intervention (PCI) cases in a contemporary Australian registry cohort. BACKGROUND: With improvements in techniques and pharmacotherapy in PCI, more complex lesions in older patients are now being attempted. In the context of PCI performance assessment, there are limited data regarding the characteristics and outcomes of unsuccessful PCI. METHOD: We prospectively collected data on patients undergoing single-lesion PCI between 2013 and 2017 who were enrolled in the multi-center Victorian Cardiac Outcomes Registry. Procedures were divided into two groups by whether or not PCI was deemed successful at the end of the procedure using a pre-specified definition. RESULTS: There were 34,383 single-lesion PCI performed, of which 18,644 (54.2%) were for acute coronary syndromes. Of the study cohort, 2080 patients (6.0%) had an unsuccessful PCI - these patients were older, more likely to have previous stroke, PCI, severe left ventricular dysfunction and chronic kidney disease (all p < 0.001). The procedure was also more likely to be performed for stable angina (p < 0.001). Chronic total occlusion PCI made up 31% of unsuccessful PCI cases. Unsuccessful PCI was itself associated with higher in-hospital and 30-day mortality and MACE (all p < 0.001). 4.9% of unsuccessful PCIs led to unplanned in-hospital bypass surgery (compared to 0.2% in successful PCIs, p < 0.001). CONCLUSION: Our study highlights that even in contemporary PCI practice, more than 1 in 20 PCI attempts are unsuccessful. Lack of procedural success has a strong influence on patient outcomes. Monitoring rates of unsuccessful cases is an important quality assurance tool.

OBJECTIVES: This study examined if sex differences in prehospital pain scores, opioid administration, and clinical outcomes exist in acute coronary syndrome (ACS) patients. BACKGROUND: Sex differences persist in ACS presentation, management, and outcomes. The impact of sex differences on prehospital pain management of ACS with opioids is unknown. METHODS: Patients presenting with ACS via ambulance (2014-2018) that underwent percutaneous coronary intervention (PCI) were prospectively collected via the Victorian Cardiac Outcomes Registry and Melbourne Interventional Group, linked to the Ambulance Victoria database. The primary outcome was 30-day major adverse cardiac events (MACE). Secondary outcomes were descriptive analyses of prehospital pain score, intravenous morphine equivalent analgesic dosing, plus predictors of MACE and thrombolysis in myocardial infarction (TIMI) 0-1 flow pre-PCI. RESULTS: A total of 10,547 patients were included (female: 2775 [26%]). Opioids were administered to 1585 (57%) females, 5068 (65%) males (p < 0.001). Adjusted 30-day MACE was similar between opioid groups in both sexes (female: odds ratio [OR]: 1.21, confidence interval [CI] 0.82-1.79, p = 0.34; male: OR: 0.89, CI: 0.68-1.16, p = 0.40). Median pain score at presentation was 6 (interquartile range [IQR]: 4, 8) for both sexes. Median opioid dose was 2.5 mg (IQR: 0, 10) in females and 5 mg (IQR: 0, 10) in males (p < 0.001), with similar pain relief achieved. Adjusted rates of TIMI 0-1 pre-PCI were higher in patients administered opioids (female: OR 2.9, CI: 2.07-4.07, p < 0.001; male: OR: 2.67, CI: 2.19-3.25, p < 0.001). CONCLUSIONS: Female patients undergoing PCI received less opioid analgesia, but no sex differences in prehospital pain scores were seen. Opioid administration was associated with impaired antegrade flow in the culprit artery in both sexes, but not short-term MACE. Trials evaluating nonopioid analgesics in ACS are needed.

PURPOSE: During the COVID-19 pandemic, widespread public health measures were implemented to control community transmission. The association between these measures and health-related quality of life (HRQOL) among patients following percutaneous coronary intervention has not been studied. METHODS: We included consecutive patients undergoing percutaneous coronary intervention (PCI) in the state-wide Victorian Cardiac Outcomes Registry between 1/3/2020 and 30/9/2020 (COVID-19 period; n = 5024), with a historical control group from the identical period one year prior (control period; n = 5041). HRQOL assessment was performed via telephone follow-up 30 days following PCI using the 3-level EQ-5D questionnaire and Australian-specific index values. RESULTS: Baseline characteristics were similar between groups, but during the COVID-19 period indication for PCI was more common for acute coronary syndromes. No patients undergoing PCI were infected with COVID-19 at the time of their procedure. EQ-5D visual analogue score (VAS), index score, and individual components were higher at 30 days following PCI during the COVID-19 period (all P < 0.01). In multivariable analysis, the COVID-19 period was independently associated with higher VAS and index scores. No differences were observed between regions or stage of restrictions in categorical analysis. Similarly, in subgroup analysis, no significant interactions were observed. CONCLUSION: Measures of HRQOL following PCI were higher during the COVID-19 pandemic compared to the previous year. These data suggest that challenging community circumstances may not always be associated with poor patient quality of life.

BACKGROUND: Delay to reperfusion in ST-elevation myocardial infarction (STEMI) is detrimental, but can be minimised with prehospital notification by ambulance to the treating hospital. We aimed to assess whether prenotification was associated with improved first medical contact to balloon times (FMC-BT) and whether this resulted in better clinical outcomes. We also aimed to identify factors associated with use of prenotification. METHODS: This was a retrospective study of prospective Victorian Cardiac Outcomes Registry data for patients undergoing primary percutaneous coronary intervention for STEMI from 2013-2018. Postcardiac arrest were excluded. Patients were grouped by whether they arrived by ambulance with prenotification (group 1), arrived by ambulance without prenotification (group 2) or self-presented (group 3). We compared groups by FMC-BT, incidence of major adverse cardiac and cerebrovascular events (MACCE), mortality and factors associated with the use of prenotification. RESULTS: 2891 patients were in group 1 (79.3% male), 1620 in group 2 (75.7% male) and 1220 in group 3 (82.9% male). Patients who had prenotification were more likely to present in-hours (p=0.004) and self-presenters had lowest rates of cardiogenic shock (p<0.001). Prenotification had shorter FMC-BT than without prenotification (104 min vs 132 min, p<0.001) Self-presenters had superior clinical outcomes, with no difference between ambulance groups. Groups 1 and 2 had similar 30-day MACCE outcomes (7.4% group 1 vs 9.1% group 2, p=0.05) and similar mortality (4.6% group 1 vs 5.9% group 2, p=0.07). In multivariable analysis, male gender, right coronary artery culprit and in-hours presentation independently predicted use of prenotification (all p<0.05). CONCLUSION: Differences in clinical characteristics, particularly gender, time of presentation and culprit vessel may influence ambulance prenotification. Ambulance cohorts have high-risk features and worse outcomes compared with self-presenters. Improving system inequality in prehospital STEMI diagnosis is recommended for fastest STEMI treatment.

BACKGROUND: Following percutaneous coronary intervention (PCI), outpatient cardiac rehabilitation (CR) is essential for secondary prevention. However uptake of CR is suboptimal, despite strong evidence demonstrating benefits. The aim of this study was to identify contemporary trends and predictors of CR referral of PCI patients in Victoria. METHODS: A prospective, observational study using data extracted from the Victorian Cardiac Outcomes Registry was undertaken. A total of 41,739 patients were discharged following PCI over the study period (2017-2020) and included for analysis. RESULTS: Cardiac rehabilitation referral was 85%, with an increasing trend over time (p<0.001). Multivariable modelling identifying the independent predictors of CR referral included hospitals with high volumes of ST-elevation myocardial infarction patients (STEMI) (OR 4.89, 95% CI 4.41-5.20), STEMI diagnosis (OR 1.90, 95% CI 1.69-2.14), or treatment in a private hospital (OR 1.45, 95% CI 1.33-1.57). Predictors of non-referral included cardiogenic shock (OR 0.54, 95% CI 0.41-0.71), aged over 75 years (OR 0.62, 95% CI 0.57-0.68) and previous PCI (OR 0.66, 95% CI 0.62-0.70). Percutaneous coronary intervention patients with an acute coronary syndrome who were referred to CR were also more likely to be prescribed four or more major preventive pharmacotherapies, compared to those who were not referred (90% vs 82.1%, p<0.001). CONCLUSION: Our contemporary multicentre analysis showed generally high CR referral rates which have increased over time. However, more effort is needed to target patients treated in the public sector, low volume STEMI hospitals or with short lengths of stay.

BACKGROUND: Acute decompensated heart failure (ADHF) is the most common cause of hospital admission in patients over 65, with poorer outcomes demonstrated in rural versus metropolitan areas. The aim of this study was to compare the in-hospital and post-discharge management of ADHF patients admitted to rural versus metropolitan hospitals in Victoria. METHODS: Data from the Victorian Cardiac Outcomes Registry, Heart Failure (VCOR-HF) project was used. This was a prospective, observational, non-randomised study of consecutive patients admitted to participating hospitals in Victoria, Australia, with ADHF as their primary diagnosis over four 30-day periods during consecutive years. All patients were followed up for 30 days post discharge. RESULTS: 1,357 patients (1,260 metropolitan, 97 rural) were admitted to study hospitals with ADHF during the study periods. Cohorts were similar in age (average 76.87±13.12 yrs) and percentage of male gender (56.4% overall). Metropolitan patients were more likely to have diabetes (44.4% vs 34.0%, p=0.046), kidney disease (65.8% vs 37.1%, p<0.01) and anaemia (31.9% vs 19.6%, p=0.01). There was no significant difference in length of stay between metropolitan and rural patients (7.49 vs 6.37 days, p=0.12). There was no significant difference between metropolitan and rural patients in 30-day rehospitalisations (19.1% vs 11.6%, p=0.07, respectively) and all-cause 30-day mortality (8.2% vs 4.1%, p=0.15, respectively). Metropolitan patients were significantly more likely to have seen their general practitioner (GP) (68.1% vs 53.2%, p<0.01) or attend an outpatient clinic (35.9% vs 10.6%, p<0.01) by 30 days. There was no significant difference in number of days to follow-up of any kind between groups. Referrals to a heart failure home visiting program remained low overall (19.9%). CONCLUSION: There was no significant difference in 30-day rehospitalisations or mortality between patients admitted to rural versus metropolitan hospitals. Geographical discrepancies were noted in follow-up by 30 days, with significantly more metropolitan patients having seen a doctor by 30 days post-discharge. Overall follow-up rates remain suboptimal.

BACKGROUND: Heart failure is increasing in prevalence, creating a greater public health and economic burden on our health care system. With a rising proportion of hospitalisations for heart failure with preserved ejection fraction (HFpEF) compared to heart failure with reduced ejection fraction (HFrEF) and lack of proven therapies for HFpEF, patient characterisation and defining clinical outcomes are important in determining optimal management of heart failure patients. There is scarce Australian-specific data with regards to the burden of disease of patients with HFpEF which further limits our ability to appropriately manage this syndrome. AIM: To determine the characteristics, management practices and outcomes of patients with HFpEF compared to patients diagnosed with HFrEF. METHOD: Data was sourced from the Victorian Cardiac Outcomes Registry-Heart Failure (VCOR-HF) snapshot of patients admitted with acute heart failure to one of 16 Victorian health services between 2014-2017 over one consecutive month annually. Outcomes measured were in-hospital mortality, and 30-day readmission and mortality. RESULTS: Of the 1,132 HF patients, 436 patients were diagnosed with HFpEF and were more likely to be female (59%) and older (81.5±9.8 vs 73.2±14.5 years). They were also more likely to have hypertension (80%), atrial fibrillation (59.9%), chronic obstructive airways disease (36.2%) and chronic kidney disease (68.8%). Patients with HFrEF were more likely to have ischaemic heart disease with a history of previous myocardial infarction (36.6%), percutaneous coronary intervention and cardiac bypass surgery (35.2%). There were no significant differences in 30-day mortality between HFpEF and HFrEF (10.2% vs 7.8%; p=0.19, respectively) and 30-day readmission rates (22.1% vs 25.9%; p=0.15, respectively). CONCLUSION: VCOR-HF Snapshot data provides important insight into the burden of acute heart failure. Whilst patients with HFpEF and HFrEF have differing clinical profiles, morbidity, mortality and re-admission rates are similar.

OBJECTIVES: Approximately 5-10% of patients presenting for percutaneous coronary intervention (PCI) have concurrent atrial fibrillation (AF). To what extent AF portends adverse long-term outcomes in these patients remains to be defined. METHODS: We analysed data from the multicentre Melbourne Interventional Group Registry from 2014-2018. Patients were identified as being in AF or sinus rhythm (SR) at the commencement of PCI. The primary endpoint was long-term mortality, obtained via linkage with the National Death Index. RESULTS: 13,286 procedures were included, with 800 (6.0%) patients in AF and 12,486 (94.0%) in SR. Compared to SR, patients with AF were older (72.9±10.9 vs 64.1±12.0 p<0.001) and more likely to have comorbidities including diabetes mellitus (31.3% vs 25.0% p<0.001), hypertension (74.4% vs 65.1% p<0.001) and moderate to severe left ventricular systolic dysfunction (36.6% vs 19.5% p<0.001). Atrial fibrillation was associated with an increased risk of in-hospital mortality (11.0% vs 2.5% p<0.001) and MACE (composite of all-cause mortality, myocardial infarction, or target vessel revascularisation) (11.9% vs 4.2% p<0.001). In-hospital major bleeding was more common in the AF group (3.1% vs 1.0% p<0.001). On Cox proportional hazards modelling, AF was an independent predictor of long-term mortality (adjusted HR 1.38 95% CI 1.11-1.72 p<0.004) at a mean follow-up of 2.3±1.5 years. CONCLUSIONS: Preprocedural AF is common among patients presenting for PCI. Preprocedural AF is associated with high-rates of comorbid illnesses and portends higher risk of short- and long-term outcomes including mortality underscoring the need for careful evaluation of its risks prior to PCI.

BACKGROUND: Percutaneous coronary intervention (PCI) in stable ischaemic heart disease (SIHD) has not been shown to improve prognosis but can alleviate symptoms and improve quality of life. Appropriately selected patients with symptoms refractory to medical therapy therefore stand to benefit, provided safety is proven. METHODS: Consecutive patients undergoing PCI for SIHD between 2005-2018 in a prospective registry were included. Yearly comparisons evaluated trends, and a sub-analysis was performed comparing proximal left anterior descending artery (prox-LAD) to other-than-proximal LAD (non-pLAD) PCI. Outcomes included peri-procedural characteristics, in-hospital and 30-day event rates including MACE, and 5-year National Death Index (NDI) linked mortality. RESULTS: There were 9,421 procedures included. Over time, patients were increasingly co-morbid and had higher rates of AHA/ACC class B2/C lesions, ostial stenoses, bifurcation lesions, and chronic total occlusions (all p-for-trend ≤0.001). Over 14 years, major bleeding reduced (1.05% in 2005/06 vs 0.29% in 2017/18, p-for-trend <0.001), while other in-hospital and 30-day event rates were stably low. There were only seven (0.07%) in hospital deaths and 5-year mortality was 10.3%. No differences were found in outcomes between patients who underwent prox-LAD compared to non-pLAD PCI. Major independent predictors of NDI linked all-cause mortality included an eGFR <30 mL/min/1.73 m2 (HR 4.06, 95% CI 3.26-5.06), chronic obstructive pulmonary disease (COPD) (HR 2.25, 95% CI 1.89-2.67) and LVEF <30% (HR 2.13, 95% CI 1.57-2.89). CONCLUSIONS: Although patient and procedural complexity increased over time, a high degree of procedural success and safety was maintained, including in those undergoing prox-LAD PCI. These real-world data can enhance shared decision making discussions regarding whether PCI should be pursued in patients with symptomatic SIHD refractory to medical therapy.

AIMS: We aimed to assess the impact of the severity of chronic kidney disease (CKD) with long-term clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). METHODS: We analyzed data on consecutive patients undergoing PCI enrolled in the Victorian Cardiac Outcomes Registry (VCOR) from January 2014 to December 2018. Patients were stratified into tertiles of renal function; estimated glomerular filtration (eGFR) ≥60, 30-59 and < 30 ml/min/1.73 m2 (including dialysis). The primary outcome was long-term all-cause mortality obtained from linkage with the Australian National Death Index (NDI). The secondary endpoint was a composite of 30 day major adverse cardiac and cerebrovascular events. RESULTS: We identified a total of 51,480 patients (eGFR ≥60, n = 40,534; eGFR 30-59, n = 9,521; eGFR <30, n = 1,425). Compared with patients whose eGFR was ≥60, those with eGFR 30-59 and eGFR<30 were on average older (77 and 78 vs. 63 years) and had a greater burden of cardiovascular risk factors. Worsening CKD severity was independently associated with greater adjusted risk of long-term NDI mortality: eGFR<30 hazard ratio 4.21 (CI 3.7-4.8) and eGFR 30-59; 1.8 (CI 1.7-2.0), when compared to eGFR ≥60, all p < .001. CONCLUSION: In this large, multicentre PCI registry, severity of CKD was associated with increased risk of all-cause mortality underscoring the high-risk nature of this patient cohort.
