Very early invasive strategy in higher risk non-ST-elevation acute coronary syndrome: the RAPID NSTEMI trial.

OBJECTIVE: To investigate whether a very early invasive strategy (IS)±revascularisation improves clinical outcomes compared with standard care IS in higher risk patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). METHODS: Multicentre, randomised, controlled, pragmatic strategy trial of higher risk patients with NSTE-ACS, defined by Global Registry of Acute Coronary Events 2.0 score of ≥118, or ≥90 with at least one additional high-risk feature. Participants were randomly assigned to very early IS±revascularisation (<90 min from randomisation) or standard care IS±revascularisation (<72 hours). The primary outcome was a composite of all-cause mortality, new myocardial infarction or hospitalisation for heart failure at 12 months. RESULTS: The trial was discontinued early by the funder due to slow recruitment during the COVID-19 pandemic. 425 patients were randomised, of whom 413 underwent an IS: 204 to very early IS (median time from randomisation: 1.5 hours (IQR: 0.9-2.0)) and 209 to standard care IS (median: 44.0 hours (IQR: 22.9-72.6)). At 12 months, there was no significant difference in the primary outcome between the early IS (5.9%) and standard IS (6.7%) groups (OR 0.93, 95% CI 0.42 to 2.09; p=0.86). The incidence of stroke and major bleeding was similar. The length of hospital stay was reduced with a very early IS (3.9 days (SD 6.5) vs 6.3 days (SD 7.6), p<0.01). CONCLUSIONS: A strategy of very early IS did not improve clinical outcomes compared with a standard care IS in higher risk patients with NSTE-ACS. However, the primary outcome rate was low and the trial was underpowered to detect such a difference. TRIAL REGISTRATION NUMBER: NCT03707314.

A randomized controlled trial to investigate the use of acute coronary syndrome therapy in patients hospitalized with COVID-19: the COVID-19 Acute Coronary Syndrome trial.

BACKGROUND: Patients hospitalized with COVID-19 suffer thrombotic complications. Risk factors for poor outcomes are shared with coronary artery disease. OBJECTIVES: To investigate the efficacy of an acute coronary syndrome regimen in patients hospitalized with COVID-19 and coronary disease risk factors. METHODS: A randomized controlled, open-label trial across acute hospitals (United Kingdom and Brazil) added aspirin, clopidogrel, low-dose rivaroxaban, atorvastatin, and omeprazole to standard care for 28 days. Primary efficacy and safety outcomes were 30-day mortality and bleeding. The key secondary outcome was a daily clinical status (at home, in hospital, on intensive therapy unit admission, or death). RESULTS: Three hundred twenty patients from 9 centers were randomized. The trial terminated early due to low recruitment. At 30 days, there was no significant difference in mortality (intervention vs control, 11.5% vs 15%; unadjusted odds ratio [OR], 0.73; 95% CI, 0.38-1.41; p = .355). Significant bleeds were infrequent and were not significantly different between the arms (intervention vs control, 1.9% vs 1.9%; p > .999). Using a Bayesian Markov longitudinal ordinal model, it was 93% probable that intervention arm participants were more likely to transition to a better clinical state each day (OR, 1.46; 95% credible interval [CrI], 0.88-2.37; Pr [beta > 0], 93%; adjusted OR, 1.50; 95% CrI, 0.91-2.45; Pr [beta > 0], 95%) and median time to discharge to home was 2 days shorter (95% CrI, -4 to 0; 2% probability that it was worse). CONCLUSION: Acute coronary syndrome treatment regimen was associated with a reduction in the length of hospital stay without an excess in major bleeding. A larger trial is needed to evaluate mortality.

CONCLUSIONS: acute coronary syndrome treatment regimen was associated with a 99 reduction in the length of hospital stay without an excess in major bleeding. a larger trial is needed to evaluate mortality.

One-year outcomes of percutaneous coronary intervention in native coronary arteries versus saphenous vein grafts in patients with prior coronary artery bypass graft surgery.

BACKGROUND: Patients with prior coronary artery bypass graft (CABG) surgery often require percutaneous coronary intervention (PCI). Data are still limited in regards to the outcomes of native saphenous vein graft (SVG) PCI after CABG. METHODS: We performed a retrospective study in a tertiary reference cardiac center of consecutive patients who underwent PCI after CABG. The data were collected for patients who underwent either native or graft PCI from January 2008 to December 2018. Arterial graft PCIs were excluded. Multivariable Cox regression analysis with propensity matching was performed, and major adverse cardiac events (MACE) outcomes including death or myocardial infarction (MI) or revascularization were assessed at 1-year after each index procedure. RESULTS: A total of 435 PCI were performed in 401 patients (209 had native PCI and 192 had graft PCI). Target lesions were classified as following: 235 (54%) native coronary arteries and 200 (46%) SVG. Propensity matching resulted in 167 matched pairs. In multivariable Cox regression graft PCI relative to native PCI was an independent risk factor for MACE (hazard ratio [HR] 1.725, 95% confidence interval [CI] 1.049-2.837) which was primarily driven by increased incidence in revascularization (HR 2.218, 95% CI 1.193-4.122) and MI (HR 2.248, 95% CI 1.220-4.142) and with no significant difference in mortality (HR 1.118, 95% CI 0.435-2.870). CONCLUSIONS: Compared with native coronary PCI, bypass graft PCI was significantly associated with higher incidence of MACE at 1-year and this was mainly driven by MI and revascularization.

Quality of Life Assessment in Patients Undergoing Trans-Catheter Aortic Valve Implantation Using MacNew Questionnaire.

The MacNew questionnaire is a disease-specific quality of life measure that has been used in patients with myocardial infarction and heart failure. We aimed to investigate the impact of transcatheter aortic valve implantation (TAVI) on health-related quality of life (HRQoL) using MacNew Questionnaire and identify predictors associated with a change in its score. This was a prospective multi-center study performed across 5 National Health Service hospitals in the United Kingdom performing TAVI between 2016 and 2018. HRQoL was assessed using MacNew Questionnaire, Euro Quality of Life-5D-5L, and Short Form 36 questionnaires collected at baseline, 3-, 6- and 12 months after the procedure. Out of 225 recruited patients, 19 did not have TAVI and 4 withdrew their consent, and hence 202 patients were included. HRQoL was assessed in 181, 161, and 147 patients at 3, 6, and 12 months, respectively. Using MacNew, there was a significant improvement in all domains of HRQoL as early as 3 months after TAVI which was sustained up to 12 months with improved discrimination of change in HRQoL compared with other scales. Poor mobility at baseline and history of myocardial infarction were independent predictors of reduced improvement in HRQoL at 3 months. HRQoL increased in all subgroups of patients including frail ones. In conclusion, the MacNew assessment tool performed well in a representative TAVI cohort and could be used as an alternative disease-specific method for assessing HRQoL change after TAVI.

Ultra-low contrast, complex left main coronary intervention case series using novel intravascular ultrasound technology.

BACKGROUND: Contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) carries a high morbidity and mortality. Ultra-low contrast percutaneous coronary intervention (ULPCI) has previously been described. Complex left main (LM) ULPCI using two-stent strategy guided by novel intravascular ultrasound (IVUS) co-registration software has not been described. We report a series of complex LM ULPCI using IVUS co-registration. CASE SUMMARIES: Five patients with estimated glomerular filtration rate ≤20 mL/min who presented with stable angina or non-ST segment elevation acute coronary syndrome underwent percutaneous coronary intervention (PCI). The patients previously had diagnostic angiography performed as a separate procedure. Successful LM ULPCI was performed in all patients with a provisional and two-stent bifurcation strategies. These were complex procedures, some of which required haemodynamic support and rotational atherectomy. DISCUSSION: This report describes the first ULPCI using a dedicated two-stent LM bifurcation strategy and using rotational atherectomy and IVUS co-registration. This technology facilitated complex PCI in this high-risk patient group with minimal contrast use (≤6 mL) with optimal results and no patients developed acute kidney injury after intervention. The adaptation of ULPCI to daily practice in patients at risk of CIN will improve treatment for this underserved patient group.

Use of dalbavancin in infective endocarditis: a case series.

BACKGROUND: Infective endocarditis, typically caused by Gram-positive organisms such as viridans group streptococci and Staphylococcus aureus, is associated with high mortality and morbidity and requires aggressive, prolonged antimicrobial treatment and sometimes surgery. Dalbavancin, a lipoglycopeptide active against Gram-positive pathogens, has a long half-life, which allows IV treatment as one dose or two doses with a prolonged interval, offering personalized treatment for complex psychosocial situations or facilitating early discharge. In the absence of randomized controlled trials in infective endocarditis, current evidence derives from real-world case series involving off-licence use. The Austrian Society for Infectious Disease and Tropical Medicine includes dalbavancin as an option for infective endocarditis. OBJECTIVES: This retrospective case series reports use of dalbavancin in a small cohort of patients with infective endocarditis treated at Lancashire Cardiac Centre, Blackpool Teaching Hospitals Foundation Trust, UK. RESULTS: The pharmacy database included 11 patients in whom dalbavancin was used to address either complex psychosocial circumstances or the need for early discharge. The endocarditis multidisciplinary team selected dalbavancin from available treatment options. Structures affected by infective endocarditis included aortic, mitral and tricuspid valves; aortic composite grafts; implantable cardioverter defibrillator leads; and prosthetic aortic valves. Eight patients underwent surgery; three were managed conservatively with antibiotics. Dalbavancin was curative in all but one patient, whose signs and symptoms of infection improved. No patients developed adverse reactions. CONCLUSIONS: Dalbavancin is an alternative treatment option at hospital discharge when conventional antibiotics may not be suitable due to complex psychosocial issues or early discharge is required.

Mental Health Outcomes Among British Healthcare Workers-Lessons From the First Wave of the Covid-19 Pandemic.

OBJECTIVE: To ascertain the level of psychological distress, using validated psychology tools, among British National healthcare workers (HCW) during the first wave of the Covid-19 crisis. METHODS: A multi-centre, anonymized, all-comer staff survey across 3 hospitals in Lancashire, England during the Covid-19 first wave (April to June 2020), consisting of Patient Health Questionnaire (PHQ-9), Perceived Stress Scale-10 (PSS-10), Generalized Anxiety Disorder-7 (GAD-7), and Impact of Events Scale (IES-6). RESULTS: Among 1113 HCW, median (IQR) PHQ-9, GAD-7, PSS-10, and IES-6 score was 7 (3 to 11), 6 (3 to 11), 19 (13 to 24), and 9 (5 to 14), respectively. Potential predictors of higher levels of psychological distress included living alone, disabled dependents, history of depression/anxiety, and being female. CONCLUSIONS: The study indicates a high prevalence of psychological distress during the acute Covid-19 period among HCW, identifies groups at risk and areas of future research.

Meta-Analysis Comparing Direct Oral Anticoagulants to Vitamin K Antagonists for The Management of Left Ventricular Thrombus.

Introduction: To compare vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) treatment in patients with left ventricular (LV) thrombus. The primary outcome was stroke or systemic embolism (SSE). Secondary outcomes were thrombus resolution, bleeding, and death.Areas covered: Five observational studies were included (total n = 700; VKAs n = 480; DOACs n = 220). There was a trend toward less SSE with VKAs compared to DOACs (5.2% vs. 9%; odds ratio [OR] = 0.54, 95% confidence interval [CI] = 0.29-1.01, p = 0.05). No significant difference between VKAs and DOACs in rates of thrombus resolution (61.6% vs. 56.8%; OR = 1.00, 95% CI = 0.58-1.73, p = 0.99), bleeding (8.2% vs. 4.4%; OR = 1.62, 95% CI = 0.69-3.77, p = 0.27), or death (12.7% vs. 11.8%; OR = 1.09, 95% CI = 0.59-2.0, p = 0.79) was noted. In non-primary percutaneous coronary intervention setting, VKAs were associated with less SSE in prespecified analysis (5.2% vs.10.6%; OR = 0.48, 95% CI = 0.25-0.93, p = 0.03).Expert opinion: The current meta-analysis suggests a trend toward higher SSE with the use of DOACs compared to VKAs. Our recommendation is for VKAs to retain the preferred management of LV thrombus with cautious off-label use of DOACs.

Hospital admission with non-alcoholic fatty liver disease is associated with increased all-cause mortality independent of cardiovascular risk factors.

Non-alcoholic fatty liver disease (NAFLD) is common and strongly associated with the metabolic syndrome. Though NAFLD may progress to end-stage liver disease, the top cause of mortality in NAFLD is cardiovascular disease (CVD). Most of the data on liver-related mortality in NAFLD derives from specialist liver centres. It is not clear if the higher reported mortality rates in individuals with non-cirrhotic NAFLD are entirely accounted for by complications of atherosclerosis and diabetes. Therefore, we aimed to describe the CVD burden and mortality in NAFLD when adjusting for metabolic risk factors using a 'real world' cohort. We performed a retrospective study of patients followed-up after an admission to non-specialist hospitals with a NAFLD-spectrum diagnosis. Non-cirrhotic NAFLD and NAFLD-cirrhosis patients were defined by ICD-10 codes. Cases were age-/sex-matched with non-NAFLD hospitalised patients. All-cause mortality over 14-years follow-up after discharge was compared between groups using Cox proportional hazard models adjusted for demographics, CVD, and metabolic syndrome components. We identified 1,802 patients with NAFLD-diagnoses: 1,091 with non-cirrhotic NAFLD and 711 with NAFLD-cirrhosis, matched to 24,737 controls. There was an increasing burden of CVD with progression of NAFLD: for congestive heart failure 3.5% control, 4.2% non-cirrhotic NAFLD, 6.6% NAFLD-cirrhosis; and for atrial fibrillation 4.7% control, 5.9% non-cirrhotic NAFLD, 12.1% NAFLD-cirrhosis. Over 14-years follow-up, crude mortality rates were 14.7% control, 13.7% non-cirrhotic NAFLD, and 40.5% NAFLD-cirrhosis. However, after adjusting for demographics, non-cirrhotic NAFLD (HR 1.3 (95% CI 1.1-1.5)) as well as NAFLD-cirrhosis (HR 3.7 (95% CI 3.0-4.5)) patients had higher mortality compared to controls. These differences remained after adjusting for CVD and metabolic syndrome components: non-cirrhotic NAFLD (HR 1.2 (95% CI 1.0-1.4)) and NAFLD-cirrhosis (HR 3.4 (95% CI 2.8-4.2)). In conclusion, from a large non-specialist registry of hospitalised patients, those with non-cirrhotic NAFLD had increased overall mortality compared to controls even after adjusting for CVD.

Meta-Analysis Comparing Percutaneous to Surgical Access in Trans-Femoral Transcatheter Aortic Valve Implantation.

To compare the outcomes in trans-femoral transcatheter aortic valve implantation (TF-TAVI) performed with percutaneous approach (PC) versus surgical cut-down (SC). In 13 trials including 5,859 patients (PC = 3447, SC = 2412), the outcomes based on Valve Academic Research Consortium criteria were compared between PC and SC in TF-TAVI. Compared with SC, PC was associated with similar major vascular complications (VCs) (8.7% vs 8.5%; odds ratio [OR] = 0.93, 95% confidence interval [CI] = 0.76 to 1.15, p = 0.53), major bleeding (OR = 1.09, 95% CI = 0.66 to 1.8, p = 0.73), perioperative mortality (5.7% vs 5.2%; OR = 1.13, 95% CI = 0.85 to 1.49, p = 0.4), urgent surgical repair (OR = 1.27, 95% CI = 0.81 to 2.02, p = 0.3), stroke (3.3% vs 3.9%; OR = 0.85, 95% CI = 0.53 to 1.36, p = 0.5), myocardial infarction (1.3% vs 1.1%; OR = 1.06, 95% CI = 0.53 to 2.12, p = 0.86), and renal failure (5.2% vs 5.9%; OR = 0.68, 95% CI = 0.38 to 1.22, p = 0.2), but shorter hospital stay (9.1 ± 8.5 vs 9.6 ± 9.5 days; mean difference = -1.07 day, 95% CI = -2.0 to -0.15, p = 0.02) and less blood transfusion (18.5% vs 25.7%; OR = 0.61, 95% CI = 0.43-0.86, p = 0.005). Minor VCs occurred more frequently in PC compared to SC (11.9% vs 6.9%; OR = 1.67, 95% CI = 1.04-2.67, p = 0.03). In conclusion, in TF-TAVI, PC is a safe and feasible alternative to SC, and adopting either approach depends on operator experience after ensuring that vascular access could be safely achieved with that specific technique.

Initial experience of a self-expanding transcatheter aortic valve with an outer pericardial wrap: The United Kingdom and Ireland Implanters' registry.

OBJECTIVES: The United Kingdom and Ireland Implanters' registry is a multicenter registry which reports on real-world experience with new transcatheter heart valves. BACKGROUND: The Evolut PRO (Medtronic, Minneapolis, MN) transcatheter aortic valve is a self-expanding transcatheter aortic valve with an outer pericardial wrap, designed to minimize paravalvular regurgitation. METHODS: Between July 2017 and December 2018, clinical, procedural, and 30-day outcome data were prospectively collected from all patients receiving the Evolut PRO valve across nine participating centers in the United Kingdom and Ireland. The primary efficacy outcome was the Valve Academic Research Consortium-2 (VARC-2)-defined endpoint of device success. The primary safety outcome was the VARC-2-defined composite endpoint of early safety at 30 days. RESULTS: A total of 317 patients underwent implantation. Mean age was 81.8 ± 6.4 years and Society of Thoracic Surgeons Predicted Risk of Mortality Score 5.5 ± 1.8%. Iliofemoral access was used in 99.1% of patients. Device success was 91.2%. Mean gradient was 7.6 ± 4.7 mmHg and effective orifice area 1.9 ± 0.7 cm2 . The incidence of moderate paravalvular regurgitation was 1.7% and there was no severe paravalvular regurgitation. A new permanent pacemaker was implanted in 17.8% of patients without a pacemaker at baseline. Early safety was demonstrated in 92.7%. At 30 days, all-cause mortality was 0.6%, stroke 3.8%, and major vascular complication 2.8%. CONCLUSIONS: Real-world experience of the Evolut PRO transcatheter aortic valve demonstrated favorable procedural success, safety, valve function, and incidence of new permanent pacemaker implantation.

Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.

BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

Balloon-assisted tracking technique as 'a way forward' for transradial intervention.

BACKGROUND: In percutaneous coronary interventions, use of the radial artery may be limited by vascular anatomy or vascular complications, such as radial artery spasm, dissection or perforation. The balloon-assisted tracking (BAT) technique is a novel and innovative method to successfully perform transradial procedures in patients with difficult vascular anatomy, severe tortuosity or radial artery spasm. In addition, the BAT technique can serve as a bail-out technique when vascular complications such as artery dissection or perforation occur. OBJECTIVE: We analysed data of all percutaneous coronary intervention patients in whom the BAT technique was undertaken in daily practice and report acute and long-term outcomes. RESULTS: A total of 62 patients were included and, in most patients, the BAT technique was performed for radial spasm. Most patients were administered benzodiazepines or nitrates before the BAT technique was performed. The primary end point, defined as successful passage of the catheter through the artery of the arm using the BAT technique, was 98%. 11% of patients developed a complication within 24 h (haematoma, prolonged pain or visible vascular damage at the end of procedure); all completely recovered at follow-up. No complications occurred during long-term follow-up. CONCLUSION: BAT is a low-risk and easy-to-use technique that increases the success rate of radial artery access and may prevent vascular complications.

Initial experience of a large, self-expanding, and fully recapturable transcatheter aortic valve: The UK & Ireland Implanters' registry.

OBJECTIVES: The UK & Ireland Implanters' registry is a multicenter registry which reports on real-world experience with novel transcatheter heart valves. BACKGROUND: The 34 mm Evolut R transcatheter aortic valve is a self-expanding and fully recapturable transcatheter aortic valve, designed to treat patients with a large aortic annulus. METHODS: Between January 2017 and April 2018, clinical, procedural and 30-day outcome data were prospectively collected from all patients receiving the 34 mm Evolut R valve across 17 participating centers in the United Kingdom and Ireland. The primary efficacy outcome was the Valve Academic Research Consortium-2(VARC-2)-defined endpoint of device success. The primary safety outcome was the VARC-2-defined composite endpoint of early safety at 30 days. RESULTS: A total of 217 patients underwent attempted implant. Mean age was 79.5 ± 8.8 years and Society of Thoracic Surgeons Predicted Risk of Mortality Score 5.2% ± 3.4%. Iliofemoral access was used in 91.2% of patients. Device success was 79.7%. Mean gradient was 7.0 ± 4.6 mmHg and effective orifice area 2.0 ± 0.6 cm2 . Paravalvular regurgitation was more than mild in 7.2%. A new permanent pacemaker was implanted in 15.7%. Early safety was demonstrated in 91.2%. At 30 days, all-cause mortality was 3.2%, stroke 3.7%, and major vascular complication 2.3%. CONCLUSIONS: Real-world experience of the 34 mm Evolut R transcatheter aortic valve demonstrated acceptable procedural success, safety, valve function, and incidence of new permanent pacemaker implantation.

Balloon assisted retraction of a migrated CoreValve Evolut R bioprosthesis during cardiac arrest.

We describe a case of balloon assisted retraction of a migrated CoreValve Evolut R bioprosthesis during trans-femoral TAVI.
