- Abstract
Aims: Currently, little evidence exists on survival and quality of care in cancer patients presenting with acute heart failure (HF). The aim of the study is to investigate the presentation and outcomes of hospital admission with acute HF in a national cohort of patients with prior cancer., Methods and Results: This retrospective, population-based cohort study identified 221 953 patients admitted to a hospital in England for HF during 2012-2018 (12 867 with a breast, prostate, colorectal, or lung cancer diagnosis in the previous 10 years). We examined the impact of cancer on (i) HF presentation and in-hospital mortality, (ii) place of care, (iii) HF medication prescribing, and (iv) post-discharge survival, using propensity score weighting and model-based adjustment. Heart failure presentation was similar between cancer and non-cancer patients. A lower percentage of patients with prior cancer were cared for in a cardiology ward [-2.4% age point difference (ppd) (95% CI -3.3, -1.6)] or were prescribed angiotensin-converting enzyme inhibitors or angiotensin receptor antagonists (ACEi/ARB) for heart failure with reduced ejection fraction [-2.1 ppd (-3.3, -0.9)] than non-cancer patients. Survival after HF discharge was poor with median survival of 1.6 years in prior cancer and 2.6 years in non-cancer patients. Mortality in prior cancer patients was driven primarily by non-cancer causes (68% of post-discharge deaths)., Conclusion: Survival in prior cancer patients presenting with acute HF was poor, with a significant proportion due to non-cancer causes of death. Despite this, cardiologists were less likely to manage cancer patients with HF. Cancer patients who develop HF were less likely to be prescribed guideline-based HF medications compared with non-cancer patients. This was particularly driven by patients with a poorer cancer prognosis., Competing Interests: Conflict of interest: M.S., B.C., L.T., M.R., P.C.L., D.A., and M.P. had financial support from the British Heart Foundation and Cancer Research UK for the submitted work; D.A. has received research funding and in-kind support for unrelated research from AstraZeneca Inc.

- Abstract
Aims: To assess the recording and accuracy of acute myocardial infarction (AMI) hospital admissions between two electronic health record databases within an English cancer population over time and understand the factors that affect case-ascertainment., Methods and Results: We identified 112 502 hospital admissions for AMI in England 2010-2017 from the Myocardial Ischaemia National Audit Project (MINAP) disease registry and hospital episode statistics (HES) for 95 509 patients with a previous cancer diagnosis up to 15 years prior to admission. Cancer diagnoses were identified from the National Cancer Registration Dataset (NCRD). We calculated the percentage of AMI admissions captured by each source and examined patient characteristics associated with source of ascertainment. Survival analysis assessed whether differences in survival between case-ascertainment sources could be explained by patient characteristics. A total of 57 265 (50.9%) AMI admissions in patients with a prior diagnosis of cancer were captured in both MINAP and HES. Patients captured in both sources were younger, more likely to have ST-segment elevation myocardial infarction and had better prognosis, with lower mortality rates up to 9 years after AMI admission compared with patients captured in only one source. The percentage of admissions captured in both data sources improved over time. Cancer characteristics (site, stage, and grade) had little effect on how AMI was captured., Conclusion: MINAP and HES define different populations of patients with AMI. However, cancer characteristics do not substantially impact on case-ascertainment. These findings support a strategy of using multiple linked data sources for observational cardio-oncological research into AMI., (© The Author(s) 2021.

- Abstract
Aims: Non-valvular atrial fibrillation (AF) greatly increases the risk of ischaemic stroke. For people with contraindications to oral anticoagulation, left atrial appendage occlusion (LAAO) provides a non-pharmacological management alternative. The aim of this study was to measure the procedural safety and longer-term effectiveness of LAAO for AF in a UK setting., Methods and Results: This was a prospective, single-armed registry of patients with AF for whom anticoagulation was unsuitable. Registry data were collected between October 2014 and April 2018 and linked to routine data sources for follow-up. Data from 583 LAAO procedures were entered into the registry, of which 537 (from 525 patients) were eligible for inclusion (median CHA2DS2-VASc score 4). A closure device was successfully implanted in 93.4% of cases, with a procedural success rate (device implanted without major complication) of 88.9%. Five patients (1.0%) died in hospital. During follow-up [median 729 (Q1:Q3, 523:913) days] 45 patients experienced neurological events; 33 of which were ischaemic. The ischaemic neurological event rate was 3.3 (1.6-5.0)% at 1 year (n = 387) and 7.0 (4.3-9.6)% at 2 years (n = 196). There were significant improvements in overall patient health (via Visual Analogue Scale) measured at 6 weeks and 6 months, but no significant improvements observed in patient utility over time., Conclusion: The findings of our study suggest that LAAO is not without procedural risk, but that this risk may be justified in high-risk patients with AF who cannot take an anticoagulant. Moreover, the data do not provide support for more widespread use of LAAO as the complication rate was relatively high and would be difficult to justify in many patients with AF who tolerate anticoagulation., (© The Author(s) 2021.

- Abstract
Aims: We hypothesized that a decline in admissions with heart failure during COVID-19 pandemic would lead to a reciprocal rise in mortality for patients with heart failure in the community., Methods and Results: We used National Heart Failure Audit data to identify 36 974 adults who had a hospital admission with a primary diagnosis of heart failure between February and May in either 2018, 2019, or 2020. Hospital admissions for heart failure in 2018/19 averaged 160/day but were much lower in 2020, reaching a nadir of 64/day on 27 March 2020 [incidence rate ratio (IRR): 0.40, 95% confidence interval (CI): 0.38-0.42]. The proportion discharged on guideline-recommended pharmacotherapies was similar in 2018/19 compared to the same period in 2020. Between 1 February-2020 and 31 May 2020, there was a 29% decrease in hospital deaths related to heart failure (IRR: 0.71, 95% CI: 0.67-0.75; estimated decline of 448 deaths), a 31% increase in heart failure deaths at home (IRR: 1.31, 95% CI: 1.24-1.39; estimated excess 539), and a 28% increase in heart failure deaths in care homes and hospices (IRR: 1.28, 95% CI: 1.18-1.40; estimated excess 189). All-cause, inpatient death was similar in the COVID-19 and pre-COVID-19 periods [odds ratio (OR): 1.02, 95% CI: 0.94-1.10]. After hospital discharge, 30-day mortality was higher in 2020 compared to 2018/19 (OR: 1.57, 95% CI: 1.38-1.78)., Conclusion: Compared with the rolling daily average in 2018/19, there was a substantial decline in admissions for heart failure but an increase in deaths from heart failure in the community. Despite similar rates of prescription of guideline-recommended therapy, mortality 30 days from discharge was higher during the COVID-19 pandemic period., (© The Author(s) 2021.

- Abstract
Aims: COVID-19 might have affected the care and outcomes of hospitalized acute myocardial infarction (AMI). We aimed to determine whether the COVID-19 pandemic changed patient response, hospital treatment, and mortality from AMI., Methods and Results: Admission was classified as non-ST-elevation myocardial infarction (NSTEMI) or STEMI at 99 hospitals in England through live feeding from the Myocardial Ischaemia National Audit Project between 1 January 2019 and 22 May 2020. Time series plots were estimated using a 7-day simple moving average, adjusted for seasonality. From 23 March 2020 (UK lockdown), median daily hospitalizations decreased more for NSTEMI [69 to 35; incidence risk ratios (IRR) 0.51, 95% confidence interval (CI) 0.47-0.54] than STEMI (35 to 25; IRR 0.74, 95% CI 0.69-0.80) to a nadir on 19 April 2020. During lockdown, patients were younger (mean age 68.7 vs. 66.9 years), less frequently diabetic (24.6% vs. 28.1%), or had cerebrovascular disease (7.0% vs. 8.6%). ST-elevation myocardial infarction more frequently received primary percutaneous coronary intervention (81.8% vs. 78.8%), thrombolysis was negligible (0.5% vs. 0.3%), median admission-to-coronary angiography duration for NSTEMI decreased (26.2 vs. 64.0 h), median duration of hospitalization decreased (4 to 2 days), secondary prevention pharmacotherapy prescription remained unchanged (each > 94.7%). Mortality at 30 days increased for NSTEMI [from 5.4% to 7.5%; odds ratio (OR) 1.41, 95% CI 1.08-1.80], but decreased for STEMI (from 10.2% to 7.7%; OR 0.73, 95% CI 0.54-0.97)., Conclusion: During COVID-19, there was a substantial decline in admissions with AMI. Those who presented to hospital were younger, less comorbid and, for NSTEMI, had higher 30-day mortality., (Published on behalf of the European Society of Cardiology.

- Abstract
Aims: Limited data exist on the impact of COVID-19 on national changes in cardiac procedure activity, including patient characteristics and clinical outcomes before and during the COVID-19 pandemic., Methods and Results: All major cardiac procedures (n = 374 899) performed between 1 January and 31 May for the years 2018, 2019, and 2020 were analysed, stratified by procedure type and time-period (pre-COVID: January-May 2018 and 2019 and January-February 2020 and COVID: March-May 2020). Multivariable logistic regression was performed to examine the odds ratio (OR) of 30-day mortality for procedures performed in the COVID period. Overall, there was a deficit of 45 501 procedures during the COVID period compared to the monthly averages (March-May) in 2018-2019. Cardiac catheterization and device implantations were the most affected in terms of numbers (n = 19 637 and n = 10 453), whereas surgical procedures such as mitral valve replacement, other valve replacement/repair, atrioseptal defect/ventriculoseptal defect repair, and coronary artery bypass grafting were the most affected as a relative percentage difference (Δ) to previous years' averages. Transcatheter aortic valve replacement was the least affected (Δ -10.6%). No difference in 30-day mortality was observed between pre-COVID and COVID time-periods for all cardiac procedures except cardiac catheterization [OR 1.25 95% confidence interval (CI) 1.07-1.47, P = 0.006] and cardiac device implantation (OR 1.35 95% CI 1.15-1.58, P < 0.001)., Conclusion: Cardiac procedural activity has significantly declined across England during the COVID-19 pandemic, with a deficit in excess of 45 000 procedures, without an increase in risk of mortality for most cardiac procedures performed during the pandemic. Major restructuring of cardiac services is necessary to deal with this deficit, which would inevitably impact long-term morbidity and mortality., (Published on behalf of the European Society of Cardiology.

- Abstract
Aims: This study aims to examine the temporal trends and outcomes in patients who undergo percutaneous coronary intervention (PCI) with a previous or current diagnosis of cancer, according to cancer type and the presence of metastases., Methods and Results: Individuals undergoing PCI between 2004 and 2014 in the Nationwide Inpatient Sample were included in the study. Multivariable analyses were used to determine the association between cancer diagnosis and in-hospital mortality and complications. 6 571 034 PCI procedures were included and current and previous cancer rates were 1.8% and 5.8%, respectively. Both rates increased over time and the four most common cancers were prostate, breast, colon, and lung cancer. Patients with a current lung cancer had greater in-hospital mortality (odds ratio (OR) 2.81, 95% confidence interval (95% CI) 2.37-3.34) and any in-hospital complication (OR 1.21, 95% CI 1.10-1.36), while current colon cancer was associated with any complication (OR 2.17, 95% CI 1.90-2.48) and bleeding (OR 3.65, 95% CI 3.07-4.35) but not mortality (OR 1.39, 95% CI 0.99-1.95). A current diagnosis of breast was not significantly associated with either in-hospital mortality or any of the complications studied and prostate cancer was only associated with increased risk of bleeding (OR 1.41, 95% CI 1.20-1.65). A historical diagnosis of lung cancer was independently associated with an increased OR of in-hospital mortality (OR 1.65, 95% CI 1.32-2.05)., Conclusions: Cancer among patients receiving PCI is common and the prognostic impact of cancer is specific both for the type of cancer, presence of metastases and whether the diagnosis is historical or current. Treatment of patients with a cancer diagnosis should be individualized and involve a close collaboration between cardiologists and oncologists., (Published on behalf of the European Society of Cardiology.

- Abstract
Background:: High survival rates are commonly reported following primary percutaneous coronary intervention for ST-elevation myocardial infarction, with most contemporary studies reporting overall survival., Aims:: The aim of this study was to describe survival following primary percutaneous coronary intervention for ST-elevation myocardial infarction corrected for non-cardiovascular deaths by reporting relative survival and investigate clinically significant factors associated with poor long-term outcomes., Methods and Results:: Using the prospective UK Percutaneous Coronary Intervention registry, primary percutaneous coronary intervention cases ( n=88,188; 2005-2013) were matched to mortality data for the UK populace. Crude five-year relative survival was 87.1% for the patients undergoing primary percutaneous coronary intervention and 94.7% for patients <55 years. Increasing age was associated with excess mortality up to four years following primary percutaneous coronary intervention (56-65 years: excess mortality rate ratio 1.61, 95% confidence interval 1.46-1.79; 66-75 years: 2.49, 2.26-2.75; >75 years: 4.69, 4.27-5.16). After four years, there was no excess mortality for ages 56-65 years (excess mortality rate ratio 1.27, 0.95-1.70), but persisting excess mortality for older groups (66-75 years: excess mortality rate ratio 1.72, 1.30-2.27; >75 years: 1.66, 1.15-2.41). Excess mortality was associated with cardiogenic shock (excess mortality rate ratio 6.10, 5.72-6.50), renal failure (2.52, 2.27-2.81), left main stem stenosis (1.67, 1.54-1.81), diabetes (1.58, 1.47-1.69), previous myocardial infarction (1.52, 1.40-1.65) and female sex (1.33, 1.26-1.41); whereas stent deployment (0.46, 0.42-0.50) especially drug eluting stents (0.27, 0.45-0.55), radial access (0.70, 0.63-0.71) and previous percutaneous coronary intervention (0.67, 0.60-0.75) were protective., Conclusions:: Following primary percutaneous coronary intervention for ST-elevation myocardial infarction, long-term cardiovascular survival is excellent. Failure to account for non-cardiovascular death may result in an underestimation of the efficacy of primary percutaneous coronary intervention.

- Abstract
Aims: The relationship between operator volume and outcomes for percutaneous coronary intervention (PCI) has been studied in the past, but recent analyses of national data covering the modern radial, acute coronary syndrome-dominant era are limited. Changing in case-mix, practice, and service provision mean that previously described volume-outcome relationships may no longer be relevant, and a reassessment in contemporary practice is needed. We aim to assess whether operator volume is associated with independently reported 30-day mortality in a contemporary PCI cohort., Methods and Results: This observational cohort study analysed procedures recorded in the British Cardiovascular Intervention Society PCI database from 2013 to 2014 in England and Wales. Mixed effects multiple logistic regression modelling was used to account for operator and centre level effects and to adjust for potential confounders. Volume is defined as the total number of procedures the operator was responsible for in the previous 12 months. A total of 133 970 procedures were analysed. Median volume across all procedures was 178 per year (interquartile range 128-239). The 30-day mortality rate was 2.6%. After adjustment for case-mix, the association between volume and mortality was negligible (odds ratio per 100 procedures 0.99, 95% confidence interval 0.93-1.05; P = 0.725). Sensitivity analyses showed similar results amongst high-risk PCI subsets and in-hospital outcomes., Conclusion: There is no evidence that mortality differs by operator volume in the UK. Volume-outcome relationships in PCI should be carefully monitored in response to future changes in practice.

- Abstract
Aims: The HORIZONS trial reported a survival advantage for bivalirudin over heparin-with-glycoprotein inhibitors (GPIs) in primary PCI for ST elevation myocardial infarction. This drove an international shift in clinical practice. Subsequent studies have produced divergent findings on mortality benefits with bivalirudin. We investigated this issue in a larger population than studied in any of these trials, using the United Kingdom national PCI registry., Methods and Results: 61 136 primary PCI procedures were performed between January 2008 and January 2012. Demographic and procedural data were obtained from the registry. Mortality information was obtained through the UK Office of National Statistics. Multivariable logistic regression and propensity analysis modelling were utilized to study the association of different anti-thrombotic strategies with outcomes. Unadjusted data demonstrated near-identical survival curves for bivalirudin and heparin-plus-GPI groups. Significantly higher early and late mortality was found in patients treated with heparin alone ( ITALIC! P < 0.0001) but this group had a markedly higher baseline risk. After propensity matching, the bivalirudin vs. heparin-plus-GPI groups still demonstrated very similar adjusted mortality (odds ratio 1.00 at 30 days, and 0.96 at 1 year). Patients treated with heparin alone continued to show higher mortality after adjustment, although effect size was considerably diminished (odds ratio vs. other groups 1.17-1.24 at 30 days)., Conclusions: Analysis of recent UK data showed no significant difference in short- or medium-term mortality between ST elevation myocardial infarction patients treated with bivalirudin vs. heparin-plus-GPI at primary PCI., (Published on behalf of the European Society of Cardiology.

- Abstract
Objectives: The first transcatheter aortic valve implantation (TAVI) in England and Wales was performed in 2007. This study presents the subsequent national activity and outcomes for both TAVI and aortic valve replacement (AVR)., Methods: Data for all AVR and TAVI procedures between January 2006 and December 2012 in England and Wales were included. The number of procedures, patient characteristics, in-hospital and 30-day mortality, postoperative length of stay (PLOS) and survival were analysed separately for: isolated AVR; AVR + coronary artery bypass graft (CABG) surgery; AVR + other surgery and TAVI., Results: The number of TAVIs increased from 66 in 2007 (0.8% of all implants) to 1186 in 2012 (10.9% of all implants). AVR activity also increased over the study period. TAVI patients were older and had a higher mean logistic EuroSCORE than all AVR groups. The 30-day mortality rates were 2.1% for isolated AVR, 3.9% for AVR + CABG, 7.7% for AVR + other surgery and 6.2% for TAVI. In-hospital mortality has significantly improved for all groups. The 5-year survival rates were 82.6% for isolated AVR, 81.7% for AVR + CABG, 74.5% for AVR + other surgery and 46.1% for TAVI. The median PLOS after TAVI was similar to that of isolated AVR but shorter than that of the other AVR groups., Conclusions: Since the introduction of TAVI, there has been an increase in both TAVI and AVR activity. TAVIs now represent over 10% of all aortic valve implants. There are distinct differences between procedural groups with respect to patient risk factors. Outcomes for all procedural groups have improved, but long-term TAVI results are required before its role in the treatment of aortic stenosis can be fully defined., (© The Author 2015.

- Abstract
The impact of operator and centre volume on clinical outcomes and quality of care has been of considerable debate in recent years in a number of surgical- and procedural-based specialities. A relationship between higher volumes at both the institutional and operator levels and better clinical outcomes would at first appear intuitive, based on the premise that performing a procedure very infrequently would be likely to lead to unfamiliarity, complications, and poorer outcomes. In the current review, we study the relationship between operator volume and outcomes in the setting of percutaneous coronary intervention (PCI), and examine the evidence for current clinical competency guidelines that advocate that a minimum number of PCI procedures be undertaken annually. Whilst both high institutional and operator volumes have been shown to be associated with better outcomes by reducing death and in-hospital mortality, these data are often derived from the pre-stent era, or when high-volume operators undertook far smaller numbers of procedures than is currently recommended to maintain clinical competency. The emphasis of specific volume requirements for optimal outcomes needs to be interpreted with caution, as volume is not a surrogate for quality and merely one of the variables associated with outcome. Healthcare providers should focus on other measures of quality such as robust clinical care pathways, evidence-based treatments, periodic case review, using validated risk assessment scores, and ascertainment of outcome to improve care and reduce adverse events.

- Abstract
Aims: This study aims to evaluate temporal changes in stroke complications and their association with mortality and MACE outcomes in a national cohort of patients undergoing percutaneous coronary interventions (PCIs) in England and Wales., Methods and Results: A total of 426 046 patients who underwent PCI in England and Wales between 2007 and 2012 in the British Cardiovascular Intervention Society (BCIS) database were analysed. Statistical analyses were performed evaluating the rates of stroke complications according to the year of PCI and multiple logistic regressions were used to evaluate the odds of 30-day mortality and in-hospital major adverse cardiovascular events (MACE; a composite of in-hospital mortality, myocardial infarction or re-infarction, and revascularization) with stroke complications. Four hundred and thirty-six patients (0.1%) sustained an ischaemic stroke/TIA complication and 107 patients (0.03%) sustained a haemorrhagic stroke complication. Ischaemic stroke/TIA complications increased non-linearly from 0.67 (95% CI 0.47-0.87) to 1.14 (0.94-1.34) per 1000 patients between 2007 and 2012 (P = 0.006), whilst haemorrhagic stroke rates decreased non-linearly from 0.29 (0.19-0.39) to 0.15 (0.05-0.25) per 1000 patients in 2012 (P = 0.009). Following adjustment for baseline clinical and procedural demographics, ischaemic stroke was independently associated with both 30-day mortality (OR 4.92, 3.06-7.92) and in-hospital MACE (OR 3.11, 1.83-5.27). An even greater impact on prognosis was observed with haemorrhagic complications (30-day mortality: OR 13.87, 6.37-30.21), in-hospital MACE (OR 13.50, 6.30-28.92)., Conclusions: Incident ischaemic stroke complications have increased over time, whilst haemorrhagic stroke complications have decreased, driven through changes in clinical, procedural, drug-treatment, and demographic factors. Both ischaemic and haemorrhagic strokes are rare but devastating complications with high 30-day mortality and in-hospital MACE rates., (Published on behalf of the European Society of Cardiology.

- Abstract
Aim: Between 10 and 30% of patients undergoing percutaneous coronary intervention (PCI) have left ventricular (LV) dysfunction. We investigate the association between LV function on early and late mortality outcomes in a national 'real-world' cohort undergoing PCI in the elective and acute coronary syndrome setting through analysis of the British Cardiovascular Intervention Society (BCIS) data set., Methods and Results: The relationship between LV function and 30-day mortality in patients undergoing PCI for elective, ST-elevation myocardial infarction (STEMI) and non-ST elevation myocardial infarction (NSTEMI) indications was studied in 230 464 patients in the UK between 2006 and 2011. Abnormal LV function was an independent predictor of 30-day mortality outcomes: 30-day mortality risk for patients with moderate LV function (EF: 30-49%) (HR: 2.91; 95% CI: 2.43-3.49, P < 0.0001) and poor LV function (EF <30%) (HR: 7.25; 95% CI: 5.87-8.96, P < 0.0001) was compared with patients with good LV function (EF >50%). The independent prognostic impact of poor LV function on 30-day mortality increased from elective PCI (HR: 3.72: 95% CI: 2.21-6.25, P < 0.0001) through to the NSTEMI (HR: 5.03: 95% CI: 3.64-6.93, P < 0.0001) and STEMI (HR: 8.18: 95% CI: 5.62-11.92, P < 0.0001)., Conclusions: Our data suggest a strong relationship between LV function and mortality outcomes following PCI, with worsening LV function independently predicting 30-day and longer-term mortality outcomes across all indications for PCI. We report a differential impact of LV function on mortality outcomes across different indications for PCI, with the greatest adverse prognostic association between worsening LV function and mortality outcomes observed in patients undergoing PCI in the STEMI setting., (Published on behalf of the European Society of Cardiology.

- Abstract
Aims: To quantify the determinants of primary percutaneous coronary intervention (PCI) performance in England and Wales between 2004 and 2007., Methods and Results: All 8653 primary PCI cases admitted to acute hospitals in England and Wales as recorded in the Myocardial Ischaemia National Audit Project (MINAP) 2004-2007. We studied the impact of the volume of primary PCI cases (hospital volume) on door-to-balloon (DTB) times and the proportion of patients treated with primary PCI (hospital proportion) on 30-day mortality and employed regression analysis to identify reasons for DTB time variations with a multilevel component to express hospital variation. The proportion of patients receiving primary PCI increased from 5% in 2004 to 20% in 2007. Median DTB times reduced from 84 min in 2004 to 61 min in 2007. Median DTB times decreased as the number of primary PCI procedures increased. The 30-day all-cause mortality rate for hospitals performing primary PCI on >25% of ST-elevation myocardial infarction patients [5.0%; 95% confidence interval (CI): 3.9-6.1%] was almost double that of hospitals performing primary PCI on more than 75% (2.7%; 95% CI: 2.0-3.5%). Time-of-day, year of admission, sex, and diabetes significantly influenced DTB times. Hospital variation was evident by a hospital-level DTB time standard deviation of 12 min., Conclusions: There was a large variation in DTB times between the best and worst performing hospitals. Although patient-related factors impacted upon DTB times, the volume and proportion of patients undergoing primary PCI were significantly associated with delay and early mortality-hospitals with the highest proportion of primary PCI had the lowest mortality.

- Abstract
Aims: Patient access to reperfusion therapy and the use of primary percutaneous coronary intervention (p-PCI) or thrombolysis (TL) varies considerably between European countries. The aim of this study was to obtain a realistic contemporary picture of how patients with ST elevation myocardial infarction (STEMI) are treated in different European countries., Methods and Results: The chairpersons of the national working groups/societies of interventional cardiology in European countries and selected experts known to be involved in the national registries joined the writing group upon invitation. Data were collected about the country and any existing national STEMI or PCI registries, about STEMI epidemiology, and treatment in each given country and about PCI and p-PCI centres and procedures in each country. Results from the national and/or regional registries in 30 countries were included in this analysis. The annual incidence of hospital admission for any acute myocardial infarction (AMI) varied between 90-312/100 thousand/year, the incidence of STEMI alone ranging from 44 to 142. Primary PCI was the dominant reperfusion strategy in 16 countries and TL in 8 countries. The use of a p-PCI strategy varied between 5 and 92% (of all STEMI patients) and the use of TL between 0 and 55%. Any reperfusion treatment (p-PCI or TL) was used in 37-93% of STEMI patients. Significantly less reperfusion therapy was used in those countries where TL was the dominant strategy. The number of p-PCI procedures per million per year varied among countries between 20 and 970. The mean population served by a single p-PCI centre varied between 0.3 and 7.4 million inhabitants. In those countries offering p-PCI services to the majority of their STEMI patients, this population varied between 0.3 and 1.1 million per centre. In-hospital mortality of all consecutive STEMI patients varied between 4.2 and 13.5%, for patients treated by TL between 3.5 and 14% and for patients treated by p-PCI between 2.7 and 8%. The time reported from symptom onset to the first medical contact (FMC) varied between 60 and 210 min, FMC-needle time for TL between 30 and 110 min, and FMC-balloon time for p-PCI between 60 and 177 min., Conclusion: Most North, West, and Central European countries used p-PCI for the majority of their STEMI patients. The lack of organized p-PCI networks was associated with fewer patients overall receiving some form of reperfusion therapy.

- Abstract
A focused review of secondary preventive medication following revascularisation provides an opportunity to ensure optimal use of these agents. A retrospective analysis of our in-house cardiothoracic surgical database was performed to identify patients undergoing non-emergency, elective surgical revascularisation discharged on four secondary preventive medications: aspirin; beta-blockers; ACE-inhibitors and statins. Of 2749 patients studied, 2302 underwent isolated coronary artery bypass grafting (CABG), mean age 65.5 years (S.D. 9.15). Overall, 2536 (92%) patients were prescribed aspirin. Beta-blockers were prescribed in 2171 (79%) patients overall, in 1096/1360 (81%) of patients with a history of myocardial infarction and in 465/619 (75%) of patients with left ventricular systolic dysfunction (LVSD). Overall, 1518 (55%) patients were prescribed an ACE-inhibitor and 179 (6.5%) an angiotensin receptor blocker (ARB); one of these agents was prescribed in 446/619 (72%) patients with LVSD and 915/1360 (67%) patients with a history of previous myocardial infarction. Overall, 2518 (92%) patients were prescribed a statin. Secondary preventive therapies are prescribed more commonly on discharge after CABG than in previous studies, but there is a continuing under-utilisation of ACE-inhibitors. To maximise the potential benefits of these agents, further study is required to understand why they are not prescribed.
