Temporal analysis of non-ST segment elevation-acute coronary syndrome (NSTEACS) outcomes in 'young' patients under the age of fifty: A nationwide cohort study

BACKGROUND

The characteristics and risk factor profile of young patients presenting with non-ST segment elevation acute coronary syndrome (NSTEACS) and how they may have changed over time is not well reported.

METHODS

We identified 26,708 NSTEACS patients aged under 50 presenting to United Kingdom (UK) hospitals between 2010 and 2017 from Myocardial Ischaemia National Audit Project (MINAP). We calculated incidence of NSTEACS per 100,000 UK population, using Office of National Statistics (ONS) population estimates, prevalence of comorbidities, ethnicity, and in-hospital mortality. We formed biennial groups to enable comparison, 2010-2011, 2012-2013, 2014-2015 and 2016-2017.

RESULTS

The incidence of NSTEACS per 100,000 population showed minimal change between 2010 and 2017 (2010: 5.4 per 100,000 and 2017; 4.9 per 100,000). Rates of smoking (2010-11; 58% and 2016-17; 53%), and family history of coronary artery disease (CAD) (2010-11; 51% and 2016-17; 44%) fell, but the proportion of patients from an ethnic minority background (2010-11; 12% and 2016-17; 20%), with diabetes mellitus (DM) (2010-11; 14%, and 2016-17; 18%) and female patients (2010-11; 22% and 2016-17; 24%) increased over the study period. Mortality from NSTEACS remained unchanged (2010-11; 1% and 2016-17; 1%).

CONCLUSIONS

The incidence of NSTEACS in patients aged under fifty has not reduced despite reduction in prevalence of risk factors such as smoking hypercholesterolaemia in those admitted to UK hospitals. Despite improved rates of early invasive coronary angiography and percutaneous coronary intervention in 'young' NSTEACS patients, in-hospital mortality remains unchanged.

Radiation protection for healthcare professionals working in catheterisation laboratories during pregnancy: a statement of the European Association of Percutaneous Cardiovascular Interventions (EAPCI) in collaboration with the European Heart Rhythm Association (EHRA), the European Association of Cardiovascular Imaging (EACVI), the ESC Regulatory Affairs Committee and Women as One

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

Overcoming professional barriers encountered by women in interventional cardiology: an EAPCI statement

Despite the increasing proportion of female medical and nursing students, there is still a significant under-representation of women working as healthcare providers in interventional cardiology, with very few of them reaching senior leadership, academic positions, or acting principal investigators, as well as actively involved in company advisory boards. In this position paper, we will describe the current status of women working in interventional cardiology across Europe. We will also provide an overview of the most relevant determinants of the under-representation of women at each stage of the interventional cardiology career path and offer practical suggestions for overcoming these challenges.

An EAPCI Expert Consensus Document on Ischaemia with Non-Obstructive Coronary Arteries in Collaboration with European Society of Cardiology Working Group on Coronary Pathophysiology & Microcirculation Endorsed by Coronary Vasomotor Disorders International Study Group

This consensus document, a summary of the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI), appraises the importance of ischaemia with non-obstructive coronary arteries (INOCA). Angina pectoris affects approximately 112 million people globally. Up to 70% of patients undergoing invasive angiography do not have obstructive coronary artery disease, more common in women than in men, and a large proportion have INOCA as a cause of their symptoms. INOCA patients present with a wide spectrum of symptoms and signs that are often misdiagnosed as non-cardiac leading to under-diagnosis/investigation and under-treatment. INOCA can result from heterogeneous mechanism including coronary vasospasm and microvascular dysfunction and is not a benign condition. Compared to asymptomatic individuals, INOCA is associated with increased incidence of cardiovascular events, repeated hospital admissions, as well as impaired quality of life and associated increased health care costs. This consensus document provides a definition of INOCA and guidance to the community on the diagnostic approach and management of INOCA based on existing evidence from research and best available clinical practice; noting gaps in knowledge and potential areas for further investigation.

EAPCI Position Statement on Invasive Management of Acute Coronary Syndromes during the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic poses an unprecedented challenge to healthcare worldwide. The infection can be life threatening and require intensive care treatment. The transmission of the disease poses a risk to both patients and healthcare workers. The number of patients requiring hospital admission and intensive care may overwhelm health systems and negatively affect standard care for patients presenting with conditions needing emergency interventions. This position statements aims to assist cardiologists in the invasive management of acute coronary syndrome (ACS) patients in the context of the COVID-19 pandemic. To that end, we assembled a panel of interventional cardiologists and acute cardiac care specialists appointed by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and from the Acute Cardiovascular Care Association (ACVC) and included the experience from the first and worst affected areas in Europe. Modified diagnostic and treatment algorithms are proposed to adapt evidence-based protocols for this unprecedented challenge. Various clinical scenarios, as well as management algorithms for patients with a diagnosed or suspected COVID-19 infection, presenting with ST- and non-ST-segment elevation ACS are described. In addition, we address the need for re-organization of ACS networks, with redistribution of hub and spoke hospitals, as well as for in-hospital reorganization of emergency rooms and cardiac units, with examples coming from multiple European countries. Furthermore, we provide a guidance to reorganization of catheterization laboratories and, importantly, measures for protection of healthcare providers involved with invasive procedures.

Diagnostic Angiograms and Percutaneous Coronary Interventions in Pregnancy

Cardiovascular disease is the leading indirect cause of maternal mortality in the UK. Pregnancy increases the risk of acute MI (AMI) by three- to fourfold secondary to the profound physiological changes that place an extra burden on the cardiovascular system. AMI is not always recognised in pregnancy and there is concern among both clinicians and patients regarding catheter-based interventions due to fears of foetal irradiation and risks to the foetus. This article evaluates the current state of knowledge on AMI in pregnancy with particular emphasis on pregnancy-associated spontaneous coronary artery dissection and percutaneous coronary intervention as the revascularisation procedure for AMI. Special considerations that must be made in patients requiring percutaneous coronary intervention for pregnancy-associated spontaneous coronary artery dissection and the current recommendations on arterial access, methods of minimising radiation and stent selection are discussed.

Percutaneous coronary and structural interventions in women: a position statement from the EAPCI Women Committee

Several expert documents on sex-based differences in interventional outcomes are now available, however this is the first position paper from the EAPCI Women Committee discussing the potential influence of sex in the percutaneous treatment of coronary and structural heart disease. Despite the misconception that coronary artery disease is a 'man's disease', contemporary data shows a growing incidence in women. However, women are under-represented in randomised coronary clinical trials (~25%). The generalisation of such studies is therefore problematic in decision-making for females undergoing coronary intervention. Differences in pathophysiology between sexes exist, highlighting the need for greater awareness amongst healthcare professionals to enable best evidence-based therapies for women as well as for men. Reassuringly, women represent half of the population included in transcatheter aortic valve implantation clinical trials and may actually benefit more. Growing evidence is also emerging for other interventional atrial procedures which may well be advantageous to women. Awareness of sex disparities is increasing, and we must all work collaboratively within our profession to ensure we provide effective care for all patients with heart disease. The EAPCI Women Committee aim to highlight such issues through this position paper and through visibility within the interventional community.

Two-year outcomes following unprotected left main stenting with first vs. new-generation drug-eluting stents: the FINE registry

AIMS

To assess two-year outcomes following first vs. new-generation drug-eluting stent (DES) implantation in unprotected left main (ULMCA) percutaneous coronary intervention.

METHODS AND RESULTS

All eligible patients from our two-centre registry treated with first and new-generation DES from October 2006 to November 2010 were analysed. The study objective was major adverse cardiac events (MACE), defined as all-cause mortality, target vessel revascularisation (TVR) and myocardial infarction (MI) at two years. In total, 186 patients were included: 93 (50.0%) treated with first vs. 93 (50.0%) with new-generation DES. No differences were observed in baseline clinical characteristics except for higher EuroSCORE with new-generation DES (3.6±2.5 vs. 4.6±2.7; p=0.007). No significant difference was observed in stenting techniques; two stents were used respectively in 53.8% vs. 44.1% (p=0.187). Notably, intravascular ultrasound guidance was more frequent with new-generation DES (46.2% vs. 61.3%; p=0.040). At 730.0 (interquartile range 365.5-1,224.5) days, there was a trend towards improved MACE with new-generation DES (31.2% vs. 19.6%; p=0.070) and a significant reduction in TVR (23.7% vs. 12.0%; p=0.038) and MI (4.3% vs. 0%; p=0.044). Notably, there were four cases of definite stent thrombosis (ST) with first vs. none with new-generation DES (p=0.044).

CONCLUSIONS

In our study, new-generation DES had a trend for less MACE and improved results with regard to MI, TVR and definite ST at two-year follow-up.

Is There Still a Survival Advantage to Bypass Surgery Over Percutaneous Intervention in the Modern Era?

The method of revascularization for multi-vessel coronary artery disease (MVD) has traditionally been coronary artery bypass grafting (CABG), however, due to recent advances in the field of percutaneous coronary intervention (PCI), this latter technique has gained in popularity and its role in guidelines has been promoted. This review aims to address the current data available for the treatment of patients with complex coronary disease, including the specific disease subset in those with diabetes mellitus, focusing on the importance of risk stratification and review by the 'Heart Team'. The concept of complete versus incomplete revascularization and the assessment of lesions utilizing functional techniques are discussed. Over recent years, PCI has grown to become the most frequently performed therapeutic intervention in medicine and continues to grow. There are encouraging data that this is an effective and safe treatment option in selected patients, however, neither strategy alone can provide a solution for the entire spectrum of patients with MVD.

ACS and STEMI treatment: gender-related issues

Cardiovascular disease is the leading cause of death amongst women, with acute coronary syndromes (ACS) representing a significant proportion. It has been reported that in women presenting with ACS there is underdiagnosis and consequent undertreatment leading to an increase in hospital and long-term mortality. Several factors have to be taken into account, including lack of awareness both at patient and at physician level. Women are generally not aware of the cardiovascular risk and symptoms, often atypical, and therefore wait longer to seek medical attention. In addition, physicians often underestimate the risk of ACS in women leading to a further delay in accurate diagnosis and timely appropriate treatment, including cardiac catheterisation and primary percutaneous coronary intervention, with consequent delayed revascularisation times. It has been acknowledged by the European Society of Cardiology that gender disparities do exist, with a Class I, Level of Evidence B recommendation that both genders should be treated in the same way when presenting with ACS. However, there is still a lack of awareness and the mission of Women in Innovation, in association with Stent for Life, is to change the perception of women with ACS and to achieve prompt diagnosis and treatment.

Comparison of percutaneous coronary intervention (with drug-eluting stents) versus coronary artery bypass grafting in women with severe narrowing of the left main coronary artery (from the Women-Drug-Eluting stent for LefT main coronary Artery disease Registry)

Women typically present with coronary artery disease later than men with more unfavorable clinical and anatomic characteristics. It is unknown whether differences exist in women undergoing treatment for unprotected left main coronary artery (ULMCA) disease. Our aim was to evaluate long-term clinical outcomes in women treated with percutaneous coronary intervention (PCI) with drug-eluting stents versus coronary artery bypass grafting (CABG). All consecutive women from the Drug-Eluting stent for LefT main coronary Artery disease registry with ULMCA disease were analyzed. A propensity matching was performed to adjust for baseline differences. In total, 817 women were included: 489 (59.8%) underwent treatment with PCI with drug-eluting stents versus 328 (40.2%) with CABG. Propensity score matching identified 175 matched pairs, and at long-term follow-up there were no differences in all-cause (odds ratio [OR] 0.722, 95% confidence interval [CI] 0.357 to 1.461, p=0.365) or cardiovascular (OR 1.100, 95% CI 0.455 to 2.660, p=0.832) mortality, myocardial infarction (MI; OR 0.362, 95% CI 0.094 to 1.388, p=0.138), or cerebrovascular accident (CVA; OR 1.200, 95% CI 0.359 to 4.007, p=0.767) resulting in no difference in the primary study objective of death, MI, or CVA (OR 0.711, 95% CI 0.387 to 1.308, p=0.273). However, there was an advantage of CABG in major adverse cardiovascular and cerebrovascular events (OR 0.429, 95% CI 0.254 to 0.723, p=0.001), driven exclusively by target vessel revascularization (OR 0.185, 95% CI 0.079 to 0.432, p<0.001). In women with significant ULMCA disease, no difference was observed after PCI or CABG in death, MI, and CVA at long-term follow-up.

A comparison of the femoral and radial crossover techniques for vascular access management in transcatheter aortic valve implantation: the Milan experience

OBJECTIVE

To compare radial and femoral crossover techniques (CT) for vascular access management in transcatheter aortic valve implantation (TAVI).

BACKGROUND

Femoral crossover for controlled angiography and balloon inflation of the therapeutic access site to facilitate safe vascular closure is beneficial but technically challenging in patients with complex femoral anatomy. An alternative approach should be available.

METHODS

Between June 2011 and March 2012, 41 transfemoral TAVI patients receiving the femoral CT were compared to 46 transfemoral TAVI patients receiving the radial CT. Outcomes were 30-day valve academic research consortium (VARC) endpoints.

RESULTS

Patients undergoing the radial CT received higher median contrast volumes (150 interquartile range [IQR]: 105-180 vs. 111 IQR: 90-139 ml; P = 0.025) but procedural radiation dose and fluoroscopy times were comparable. Thirty day all cause and cardiovascular death were similar between radial and femoral CT groups (respectively 2.4% vs. 7.9%, P = 0.258 and 0% vs. 7.9%, P = 0.063). There were no differences in major vascular complications (4.3% vs. 7.3%, P = 0.553), life threatening or major bleeding events (respectively 9.1% vs. 19.5%, P = 0.168 and 13.6% vs. 22%, P = 0.315).

CONCLUSION

In TAVI cases with unfavorable contralateral femoral anatomy, radial CT for vascular access management is a reasonable alternative to the femoral CT.

New-generation drug-eluting stent experience in the percutaneous treatment of unprotected left main coronary artery disease: the NEST registry

OBJECTIVES

To explore the 2-year clinical outcomes in patients with unprotected left main coronary artery (ULMCA) disease treated with overall new drug-eluting stent (DES) options.

BACKGROUND

Recent available data have shown the feasibility and the safety of new DESs, mainly evaluating the everolimus-eluting stents in the setting of ULMCA disease.

METHODS

Patients with ULMCA disease undergoing percutaneous coronary intervention (PCI) with everolimus-, zotarolimus-, and biolimus A9-eluting stents were prospectively evaluated. The study objective was the composite of major adverse cardiac events (MACEs), consisting of all-cause mortality, myocardial infarction (MI), and target vessel revascularization (TVR) at 2-year clinical follow-up.

RESULTS

A total of 154 patients were analyzed. The mean EuroSCORE and SYNTAX scores were 4.7 ± 2.6 and 27.5 ± 8.3, respectively. Distal location was present in 126 patients (81.8%) and 96 lesions (76.3%) were true Medina bifurcations. The 2-stent technique was used in 73 cases (57.9%). Everolimus-, zotarolimus-, and biolimus A9-eluting stents were implanted in 68 patients (44.2%), 46 patients (29.9%), and 40 patients (25.9%), respectively. At a median clinical follow-up of 551.5 days (interquartile range, 360.8-1045.5 days), MACEs occurred in 29 patients (18.8%). Ten patients (6.5%) died, and 2 deaths (1.3%) were adjudicated as cardiac. No patient had myocardial infarction or definite stent thrombosis (ST). One probable and 1 possible ST were adjudicated. TVR was required in 19 patients (12.3%) and target lesion revascularization was required in only 7 patients (4.5%).

CONCLUSIONS

In our experience, despite the presence of complex distal left main lesions, new DESs in ULMCA disease appear to be promising in terms of safety and efficacy at 2-year clinical follow-up.

A "modified crossover technique" for vascular access management in high-risk patients undergoing transfemoral transcatheter aortic valve implantation

OBJECTIVES

To describe results from our "modified crossover technique" for vascular access management during transcatheter aortic valve implantation (TAVI).

BACKGROUND

Vascular access management remains a major cause of complications following TAVI due to the large bore sheaths required.

METHODS

All suitable patients undergoing TAVI in our center, between June and August 2011, underwent our "modified crossover technique," which enables the passage of a balloon through left radial access and inflation in the proximal iliac to allow percutaneous closure in a clean field.

RESULTS

In total, 15 patients were included: the logistic EuroSCORE was 19.7 ± 12.1% and STS score 5.7 ± 5.6%. The mean therapeutic femoral access site diameter was 8.1 ± 1.0 mm. Ten (66.7%) patients received Edwards SAPIEN™ XT (two using the new E-sheath) and five (33.3%) patients a Medtronic CoreValve ReValving System® device. The "modified crossover technique" was used successfully in all patients. There were three vascular complications occurring at the therapeutic access site: one rupture of the external iliac artery, one Prostar failure, and one pseudoaneurysm of the right common femoral artery. All complications were successfully treated percutaneously with covered stent implantation via access from the contralateral femoral artery. In view of the balloon inflation from the left radial artery, the complications could be treated in a clean field with minimal blood loss.

CONCLUSIONS

Our "modified crossover technique" using the left radial artery as the diagnostic site for balloon inflation appears a helpful adjunct in managing TAVI vascular access sites.

Left main thrombotic occlusion following balloon aortic valvuloplasty for severe aortic stenosis

Percutaneous balloon aortic valvuloplasty is used in high-risk patients with significant aortic stenosis, either as palliation or as a bridge to more definitive treatment. We report the case of a high-risk patient, a man aged 71 years and with multiple comorbidities, undergoing this procedure. Following the procedure, he was given protamine to aid with vascular closure. This immediately led to hemodynamic collapse and cardiopulmonary arrest with angiographic evidence of thrombus occluding the left main coronary artery. This extremely rare complication requires prompt and aggressive treatment to enable good functional recovery of the individual.
