- Abstract
\ud Objectives\ud This study presents the United Kingdom and Ireland real-world learning curve experience of the EvolutTM R (Medtronic, Minneapolis, Minnesota, USA) transcatheter heart valve.\ud \ud Background\ud The EvolutTM R is a self-expanding, repositionable and fully recapturable second-generation transcatheter heart valve with several novel design features to improve outcome, and reduce complications.\ud \ud Methods\ud Clinical, procedural, and 30-day outcome data were prospectively collected for the first 264 patients to receive an Evolut RTM valve in the United Kingdom and Ireland.\ud \ud Results\ud 264 consecutive EvolutTM R implants were performed across 9 centers. Mean age was 81.1 ± 7.8 years and mean Logistic EuroScore was 19.9 ± 13.7%. Procedural indications included aortic stenosis (72.0%), mixed aortic valve disease (17.4%) and failing aortic valve bioprostheses (10.6%).\ud \ud Conscious sedation was used in 39.8% of cases and transfemoral access in 93.6%. The procedural success rate was 91.3%, and paravalvular leak immediately after implantation was mild or less in 92.3%. Major complications were rare: cardiac tamponade 0.4%; conversion to sternotomy 0.8%; annular rupture 0.0%; coronary occlusion 0.8%; major vascular 5.3%; acute kidney injury 6.1%; new permanent pacemaker implantation 14.7%; and procedural-related death 0.0%. \ud \ud At 30-day follow-up survival was 97.7%, paravalvular leak was mild or less in 92.3% and stroke rate was 3.8%.\ud \ud Conclusions\ud This registry represents the largest published real-world experience of the EvolutTM R valve. Procedural success rate was high and safety was excellent, comparable to previous studies of the EvolutTM R valve and other second-generation devices. The low rate of complications represents an improvement on first-generation devices.

- Abstract
Background: The Synergy Megatron
TM is an everolimus-drug eluting stent that may offer advantages in the treatment of aorto-ostial disease and large proximal vessels., Aims: To report the short- to medium-term clinical outcomes from the European Synergy MegatronTM Implanters' Registry., Methods: This registry was an investigator-initiated study conducted at 14 European centers. The primary outcome was target lesion failure (TLF), defined as the composite of cardiovascular death, target vessel myocardial infarction (MI), and target lesion revascularisation., Results: Five hundred seventy-five patients underwent PCI with MegatronTM between 2019 and 2021. Patients were 69 ± 12 years old, 26% had diabetes mellitus, 24% had moderate-severe left ventricular impairment and 59% presented with an acute coronary syndrome. 15% were deemed prohibitively high risk for surgical revascularisation. The target vessel involved the left main stem in 55%, the ostium of the RCA in 13% and was a true bifurcation (Medina 1,1,1) in 50%. At 1 year, TLF was observed in 40 patients, with 26 (65%) occurring within the first 30 days. The cumulative incidence of TLF was 4.5% at 30 days and 8.6% (95% CI 6.3-11.7) at 1 year. The incidence of stent thrombosis was 0.5% with no late stent thromboses. By multivariate analysis, the strongest independent predictors of TLF were severe left ventricular impairment (HR 3.43, 95% CI: 1.67-6.76, p < 0.001) and a target vessel involving the left main (HR 4.00 95% CI 1.81-10.15 p = 0.001)., Conclusions: Use of the Synergy MegatronTM everolimus eluting stent in a 'real-world' setting shows favorable outcomes at 30 days and 1 year., (© 2023 The Authors.

- Abstract
Obesity is reported to have a protective effect on mortality in pulmonary hypertension (PH), a phenomenon known as obesity paradox. However, the data are conflicting, with some studies showing decreased mortality while other studies found no effect of obesity on mortality. Therefore, we performed a systematic review and meta-analysis to examine whether there is an association between obesity and mortality in PH. Only patients with PH diagnosed by right heart catheterization were included. We also performed a sub-group analysis of subjects with pre-capillary PH only. A total of six studies met the inclusion criteria, with a sample size of 13,987 patients. Obese subjects had lower mortality compared to non-obese subjects in the combined pre- and post-capillary PH group (hazard ratio 0.79, 95% CI 0.66-0.95, p = 0.01). While obesity was associated with reduction in mortality in the pre-capillary PH group (hazard ratio 0.77, 95% CI 0.60 to 0.98, p = 0.03), this was not uniform across all studies.

- Abstract
Background: Injury surveillance is the cornerstone of any prevention program. However the same pertaining to women's boxing is meager. We hence intended to analyse the incidence, pattern and characteristics of injuries in female boxers during the 4th Elite Women's National Boxing Championship, 2019, in India., Methods: A total of 235 female Indian boxers participated in the tournament. Injuries from the competition injury database maintained in accordance with the injury code proposed by the Australian Sports Injury Data Dictionary were compiled to observe the pattern and analysed. The outcomes measured were incidence in terms of injury rate and injury risk and injury pattern in terms of site, nature, mechanism, severity and time of injury., Results: The injury rate was observed to be 43.98 injuries per 1000 athlete bouts of exposure (95% confidence interval [CI]: 33.71-54.07) and 293.21 injuries per 1000 athlete hours of competition (95% CI: 225.94-360.47). The most commonly injured site was head, face and neck regions. Most injuries were bruises/contusions followed by cuts and epistaxis. No concussions were reported., Conclusion: This study observed that women are less prone to injuries than their male counterparts, even though a logical comparison is difficult because of the lack of data and standardization in women's boxing., Competing Interests: The authors have none to declare., (© 2021 Director General, Armed Forces Medical Services.

- Abstract
Background: Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) caused by an immunological reaction to repeated inhalational exposure to antigens. The etiology and exact immunopathology are poorly understood. Autoimmunity overlapping with HP has been described but the role of concomitant autoimmunity in the clinical course and outcome of the HP is not clearly established. In this study, we examined patients diagnosed with HP and compare them to patients with concomitant HP and autoimmunity., Methods: Patients were retrospectively screened from a single-center ILD registry. Patients > 18 years with an established multidisciplinary diagnosis of HP were included in the study. Patients with HP without autoimmune features and patients with HP with autoimmune features (HPAF) were assessed. We compared the demographics, clinical characteristics, treatment, and outcomes between the two groups. We used a Cox proportional hazards model to compare lung transplant-free survival outcomes of patients with HPAF to those with non-HPAF HP patients., Results: Of 73 patients with HP, 43 were diagnosed with HPAF. Patients with HPAF had a higher echocardiographic probability of pulmonary hypertension as compared to non-HPAF HP patients [48.8 vs 23.3%, p = 0.028, Crude odds ratio (cOR) = 3.14]. Symptomatically, those with HPAF reported a higher prevalence of arthritis as compared to non-HPAF HP (20.9 vs 3.3%, p = 0.040, cOR = 7.68). No significant differences between pulmonary function tests, oxygen requirements, mortality, and lung transplantation rates were found between the two groups. There was no statistically significant difference in transplant-free survival (p = 0.836)., Conclusion: Patients with HPAF had a higher echocardiographic probability of pulmonary hypertension as compared to patients with non-HPAF HP. The clinical characteristics and outcomes did not differ between the two groups and concomitant autoimmunity among the HP group did not portend a poorer prognosis., (© 2022.

- Abstract
Emergency percutaneous coronary intervention of the left main (LM ePCI) coronary artery necessitated by acute coronary syndrome is associated with a high risk of mortality. However, optimal treatment strategies and related outcomes remain undefined in this group. We undertook a multi-center, retrospective, observational cohort study of consecutive patients requiring LM ePCI between 2011 and 2018 and reported the coronary anatomy, treatment strategies, outcomes, and predictors of mortality. A total of 116 consecutive cases were included. Patients were predominantly male (85%) with a median age of 68.0 years; 12 patients (10%) had previous coronary artery bypass grafting. ST-elevation was noted in 76 (66%); 30 (26%) presented with an out-of-hospital cardiac arrest (OOHCA) and 47 (41%) with cardiogenic shock. The most frequent pattern of disease was Medina 1,1,1, seen in 59 patients (51%). The commonest revascularization strategy was provisional stenting (95 cases, 82%) with improved or thrombolysis in myocardial infarction 3 flow seen in 85 cases (73%). All-cause mortality was 35% at 30 days, rising to 58% at 5 years. Adverse predictors of 30-day mortality included presentation with cardiogenic shock (p = 0.018) and OOHCA (p = 0.020), whereas improved flow and/or thrombolysis in myocardial infarction 3 flow in both circumflex and left anterior descending artery afforded a better prognosis (p = 0.028). In conclusion, patients who underwent LM ePCI are a high-risk subgroup and commonly present with cardiogenic shock and OOHCA. Provisional stenting appears to be the preferred option with the successful restoration of coronary flow in most cases despite complex anatomy. High 30-day mortality is driven by the presence of cardiogenic shock, OOHCA, and failure to restore or improve coronary flow., Competing Interests: Disclosures The authors have no conflicts of interest to declare., (Copyright © 2022 Elsevier Inc.

- Abstract
Objective: We aimed to determine the prevalence and clinical characteristics of self-reported hyperthyroidism in patients with sarcoidosis., Methods: A national registry-based study investigating 3836 respondents to the Sarcoidosis Advanced Registry for Cures questionnaire in the period between June 2014 and August 2019 was conducted. This registry is generated from a web-based questionnaire that is self-reported by patients with sarcoidosis. We compared patients with sarcoidosis who had hyperthyroidism with those who did not. We used multivariate logistic regression analysis to study the association between hyperthyroidism and different cardiac manifestations in patients with sarcoidosis., Results: Three percent of the study respondents self-reported having hyperthyroidism and were generally middle-aged Caucasian women. Compared with patients without hyperthyroidism, patients with hyperthyroidism had more sarcoidosis-related comorbidities (59% vs 43%, P = .001) and more steroid-related comorbidities (56% vs 44%, P = .01), but there was no difference in the sarcoidosis-specific treatments they received, which included corticosteroids. Patients with hyperthyroidism reported sarcoidosis involvement of the heart (26.6% vs 14.9%, P = .005), kidneys (14.9% vs 8%, P = .033) and sinuses (17.7% vs 10.2%, P = .030) more frequently. Cardiac manifestations that were more frequently reported in patients with hyperthyroidism included atrial arrhythmias (11.3% vs 6.3%, P = .046), ventricular arrhythmias (17.2% vs 7.5%, P < .001), congestive heart failure (10.4% vs 5%, P = .017), and heart block (9.4% vs 4.7%, P = .036)., Conclusion: Hyperthyroidism is infrequent in patients with sarcoidosis but is potentially associated with different cardiac manifestations. We suggest considering routine screening for hyperthyroidism in patients with sarcoidosis, especially in those with cardiac involvement. Further studies are needed to investigate the impact of identifying and treating hyperthyroidism in patients with sarcoidosis., (Copyright © 2022 AACE. Published by Elsevier Inc.

- Abstract
Background: Patients with acute respiratory distress syndrome (ARDS) are highly susceptible to developing delirium for a multitude of reasons. Previous studies have linked pre-existing depression with an increased risk of postoperative delirium in patients undergoing cardiac and non-cardiac surgery. However, the evidence regarding the association between pre-existing psychiatric illnesses and delirium in ARDS patients is unknown. In this study, we aim to determine the relationship between pre-existing psychiatric illness and the risk of development of delirium amongst ARDS patients., Study Design and Methods: We performed a retrospective study of a mixed group of patients admitted to the intensive care unit (ICU) between January 2016 and December 2019 with a diagnosis of ARDS per the Berlin definition. The study group was divided into 2 cohorts: subjects with delirium and subjects without delirium. Comparison between the 2 groups was conducted to examine the impact of pre-existing psychiatric illnesses including major depressive disorder (MDD), generalized anxiety disorder (GAD), bipolar disorder, schizophrenia, or post-traumatic stress disorder. Multivariable logistic regression analysis was performed adjusting for benzodiazepine use, sedatives, analgesics, sequential organ failure assessment score, and corticosteroid use to determine the association between pre-existing psychiatric disorders and delirium., Results: 286 patients with ARDS were identified; 124 (43%) of whom were diagnosed with ICU delirium. In patients diagnosed with ICU delirium, 49.2% were found to have preexisting psychiatric illnesses, compared to 34.0% without any preexisting psychiatric illness (OR = 1.94, P = 0.01). In a subgroup analysis of individual psychiatric illnesses, GAD and MDD were associated with the development of delirium (OR = 1.88, P = 0.04 and OR = 1.76, P = 0.05 respectively)., Interpretation: ARDS patients with preexisting psychiatric illnesses, particularly GAD and MDD are associated with an increased risk of developing ICU delirium. Clinicians should be aware of the effect of psychiatric co-morbidities on developing delirium in critically ill patients.

- Abstract
Right ventricular (RV) dysfunction and pulmonary hypertension (PH) occurs in approximately one-third of patients with interstitial lung disease (ILD) and is associated with reduced 6-minute walk distance (6MWD), and increased hospitalizations and mortality. Although the impact of RV dysfunction and PH has been well described in several types of ILD, data is scarce on antisynthetase syndrome. Therefore, we sought to examine the presence of RV dysfunction and PH in patients with antisynthetase syndrome and the impact on clinical outcomes. We conducted a retrospective study of patients with antisynthetase syndrome. Seventy-five subjects were identified. Fifty-one (68%) subjects had echocardiographic data. Patients were grouped into those with normal fractional area change (FAC) ≥ 35% and reduced FAC < 35%. Clinical, echocardiographic, and right heart catheterization data were compared between the two groups. Subjects with FAC < 35% had lower diffusion capacity of the lung for carbon monoxide (29% vs. 47%, p = 0.004), fibrotic features on computed tomography of the chest (79% vs. 33%, p = 0.005), larger RV diameter (5.4 vs. 3.9 cm, p < 0.001), higher right atrial pressures (8 vs. 5 mmHg, p = 0.02), and required supplemental oxygen more frequently (100% vs. 44%, p < 0.001) compared to those with FAC ≥ 35%. We found no difference in 6MWD and hospitalizations between the two groups. The presence of RV dysfunction in antisynthetase syndrome may identify patients at risk of poor outcomes., Competing Interests: The authors declare no conflicts of interest., (© 2022 The Authors.

- Abstract
Proteus syndrome is a rare progressive multisystem disorder characterized by asymmetric, disproportionate overgrowth of bone, skin, and other tissue types. Molecular pathogenesis has been identified as somatic activating mutations of the AKT1 gene. The presentation of Proteus syndrome is exceptionally variable. Respiratory complications include emphysematous lung disease and predisposition to pulmonary emboli, the latter of which is a significant source of mortality. Pulmonary hypertension due to longstanding hypoxic lung disease as well as chronic thromboembolic events has been observed in this population. In contrast, precapillary pulmonary arterial hypertension in the absence of chronic pulmonary emboli and parenchymal lung disease has not been described in the literature on patients with Proteus syndrome. We report such a case in a young patient with Proteus syndrome, reviewing subsequent management and emphasizing the need for a detailed investigation of dyspnea., Competing Interests: The authors declare no conflict of interest., (© 2022 The Authors.

- Abstract
Introduction: Ustekinumab-induced eosinophilic pneumonia is rare and to our knowledge, this is the fifth reported case of such an entity., Case Study: A 60-year-old female was admitted with worsening shortness of breath and a nonproductive cough for 4 months. Her past medical history was significant for Crohn's disease and psoriatic arthritis that was previously managed with adalimumab and switched to ustekinumab 2 months before symptoms. Initial diagnostic workup showed 10% peripheral eosinophilia and a CT chest showed numerous 5 mm nodules scattered throughout the lungs along with some peripheral reticulations. Her BAL fluid analysis showed abnormally high eosinophil count (67%), greatly limiting her potential diagnoses to eosinophilic pneumonia, EGPA, and tropical pulmonary eosinophilia (TPE). AEP typically causes more severe disease with a rapid onset, and there was low suspicion for TPE based on history, leaving EGPA and CEP. Based on her negative autoimmune serology, a negative biopsy of the nasal mucosa (no vasculitis/granulomata or eosinophils), and negative infectious workup, the patient was diagnosed with CEP secondary to ustekinumab and the drug was stopped. She was started on high dose prednisone and after a prolonged taper over 5 months, her symptoms and nodules and reticulations on her CT scan resolved., Discussion: This case exemplifies the importance of identifying drug-induced lung diseases which in many cases might not have a strong temporal association with the symptom onset. It also highlights that some drugs owing to their long elimination half-time can remain in the system for a prolonged period and continues to cause symptoms despite their cessation and require prolonged treatment and reassurance., Conclusion: The association of eosinophilic pneumonia with ustekinumab, a drug used in the treatment of psoriasis and other autoimmune diseases, is rare and there is a paucity of literature regarding this association.

- Abstract
Background: Macrophage activating syndrome (MAS) is a form of hemophagocytic lymphohistiocytosis (HLH), a rare complication of autoimmune disease that is characterized by cytokine storm and multiorgan failure., Case Summary: A 32-year-old male presented with acutely decompensated pulmonary arterial hypertension and right heart failure secondary to MAS. The patient was immediately started on inhaled and intravenous epoprostenol, vasopressors and dexamethasone and anakinra were administered. Despite the therapies given, the patient's condition continued to decline, and he was placed on veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support. Over a few days, his clinical condition improved, and he was decannulated from VA-ECMO and later transitioned oral treprositinil and was discharged home. Due to its non-specific clinical manifestations, the diagnosis of MAS depends on high clinical suspicion and initial laboratory work up such as thrombocytopenia, transaminitis, hyperferritinemia, hypertriglyceridemia, hypofibrinogenemia, etc. In our patient, MAS led to decompensated Pulmonary Arterial Hypertension (PAH) leading to right heart failure that was refractory to inhaled and intravenous epoprostenol and vasopressors and required VA-ECMO as a bridge to recovery while his MAS was managed by anakinra and dexamethasone., Conclusion: MAS can result in acute decompensation of PAH and right heart failure. Besides RV failure management, immunosuppressants such as anakinra, etoposide, etc. should be utilized early in the management of MAS. In refractory right heart failure, VA-ECMO can be considered as a bridge to recovery. There is a paucity of literature supporting the utilization of VA-ECMO in the management of refractory right heart failure caused by MAS in adults and much of the data stems from pediatric studies. This case serves as a fine example of successful use of VA-ECMO in adult population., Competing Interests: None of the authors associated with this manuscript have any conflict of interest., (© 2021 Published by Elsevier Ltd.)

- Abstract
Although patients with COVID-19 can have mild nonspecific myalgia and mild elevation of creatinine kinase levels, severe myalgia along with elevation of creatinine kinase levels >10 times the upper normal limit and dark-colored urine indicate an underlying severe rhabdomyolysis. This report describes a 60-year-old morbidly obese man who was found to have severe rhabdomyolysis, along with acute kidney injury, dark-colored urine, and a positive COVID-19 test. He had a prolonged hospital course requiring continuous renal replacement therapy, mechanical ventilation, and multiple vasopressors and eventually died of multiorgan failure. The management of severe rhabdomyolysis and COVID-19 is challenging, and fluid resuscitation should be done cautiously, monitoring for early signs of fluid overload., (Copyright © 2021 Baylor University Medical Center.)

- Abstract
Introduction: We aimed to investigate the optimal timing of invasive coronary angiography and subsequent intervention in non-ST-segment elevation acute myocardial infarction (NSTEMI) patients., Methods: We examined the impact of early (≤24 h) versus delayed (>24 h) intervention in a large observational cohort of 20,882 consecutive NSTEMI patients treated with PCI between 2005 and 2015 at 8 tertiary cardiac centers in London (UK) using Cox-regression analysis and propensity matching., Results: Mean age was 64.5 ± 12.7 years and 26.1% were females. A quarter (27.6%), were treated within 24 h. Patients treated within 24 h were slightly younger (62.8 ± 12.8 vs. 65.2 ± 12.6, p < 0.001), most commonly male (76% vs. 72.9%, p < 0.001) and were more frequently ventilated (2.3% vs. 1.4%, p < 0.001) and in cardiogenic shock (3.6% vs. 1.4%, p < 0.001) with dynamic changes on their ECG (84.5% vs. 76.1% p < 0.001). At a median follow up of 4.2 years (interquartile range 1.8 to 7) 17.7% of patients had died. Estimated 5-year survival in patients treated within 24 h was 84.6% vs. 81% for those treated >24 h following their presentation (p < 0.001). This survival benefit remained following adjustment for confounders; HR
(delayed vs. early management) 1.11 (95%CI 1.003 to 1.23, p = 0.046). In the propensity matched cohort of 4356 patients in each group, there remained a trend for higher survival in the early intervention group (p = 0.061)., Conclusions: Notwithstanding the limitations of the retrospective design, this real-world cohort of NSTEMI patients suggests that an early intervention (≤24 h) may improve mid-term survival., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2020 Elsevier Inc.

- Abstract
Background: Obese subjects are at higher risk of development and progression of ARDS. There are limited data regarding mechanical ventilation practices and use of adjunctive therapies in subjects with ARDS across different obesity classes. We hypothesized that the adherence to lung-protective ventilation would be worse with rising body mass index class in patients with ARDS., Methods: We conducted a retrospective observational study of subjects with ARDS. We evaluated the differences in ventilator settings, airway pressures, gas exchange, use of rescue therapies, length of hospital stay, and mortality among subjects based on the obesity classes of the WHO., Results: The study included 613 subjects with ARDS: 21.4% were normal weight, 25% were overweight, and 53.7% were obese; 33.3% of the obese subjects met criteria for class I-II obesity, while 20.4% were class III obese (morbid obesity). On day 1, 53% of subjects with class III obesity had tidal volumes > 8 mL/kg, compared to 26% of the subjects with normal weight. In addition, 48% of the morbidly obese subjects received at least one rescue therapy as compared to 37% of normal weight subjects and 36% of overweight subjects. There were significant differences in the use of rescue therapies among the groups. In a multivariable model, subjects with class III obesity were significantly more likely to receive tidal volume > 8 mL/kg predicted body weight on day 1 when compared with subjects with normal weight (odds ratio 3.14, 95% CI 1.78-5.57). There was no difference in length of stay in ICU or hospital, duration of mechanical ventilation, or adjusted ICU or hospital mortality among the 4 groups., Conclusions: In this study, the risk of exposure to higher tidal volumes and the need for specific rescue therapies rose with higher classes of obesity in subjects with ARDS. More research is needed to identify how to better implement lung-protective ventilation in patients with obesity., Competing Interests: Mr Chatburn has disclosed relationships with IngMar Medical, Drive/DeVilbiss, and imtmedical. The remaining authors have disclosed no conflicts of interest., (Copyright © 2020 by Daedalus Enterprises.)

- Abstract
Introduction : Azathioprine is an immune-modulating agent used in the management of autoimmune diseases and in preventing graft rejection. Its role in the management of refractory asthma is not very well-established. Case study : A 47-year-old female with an underlying severe refractory asthma, managed with high dose steroids, was seen as an outpatient. Her course was complicated by frequent asthma exacerbation and severe adverse effects of chronic steroid use. Her symptoms did not respond to standard asthma management per Guidelines for the Diagnosis and Management of Asthma 1. She was tried on other management which included methotrexate and omalizumab injections without success. Azathioprine was started as a steroid-sparing agent following which her symptoms showed dramatic improvement with fewer exacerbations, higher peak flow measurements, and she was able to wean down her daily prednisone dose from 60 mg/day to 5 mg/day. Conclusion : Azathioprine is still an investigational agent for the management of asthma and more research needs to be done to evaluate its role. To our knowledge, this is the second case report which details the therapeutic role of Azathioprine in the management of asthma.

- Abstract
Background Limited information exists regarding procedural success and clinical outcomes in patients with previous coronary artery bypass grafting (CABG) undergoing percutaneous coronary intervention (PCI). We sought to compare outcomes in patients undergoing PCI with or without CABG. Methods and Results This was an observational cohort study of 123 780 consecutive PCI procedures from the Pan-London (UK) PCI registry from 2005 to 2015. The primary end point was all-cause mortality at a median follow-up of 3.0 years (interquartile range, 1.2-4.6 years). A total of 12 641(10.2%) patients had a history of previous CABG, of whom 29.3% (n=3703) underwent PCI to native vessels and 70.7% (n=8938) to bypass grafts. There were significant differences in the demographic, clinical, and procedural characteristics of these groups. The risk of mortality during follow-up was significantly higher in patients with prior CABG (23.2%; P =0.0005) compared with patients with no prior CABG (12.1%) and was seen for patients who underwent either native vessel (20.1%) or bypass graft PCI (24.2%; P <0.0001). However, after adjustment for baseline characteristics, there was no significant difference in outcomes seen between the groups when PCI was performed in native vessels in patients with previous CABG (hazard ratio [HR],1.02; 95%CI, 0.77-1.34; P =0.89), but a significantly higher mortality was seen among patients with PCI to bypass grafts (HR,1.33; 95% CI, 1.03-1.71; P =0.026). This was seen after multivariate adjustment and propensity matching. Conclusions Patients with prior CABG were older with greater comorbidities and more complex procedural characteristics, but after adjustment for these differences, the clinical outcomes were similar to the patients undergoing PCI without prior CABG. In these patients, native-vessel PCI was associated with better outcomes compared with the treatment of vein grafts.

- Abstract
Amino-aromatic compounds, 2-amino-4-nitrotoluene (ANT), and 2,4-diaminotoluene (DAT) are carcinogens and environmentally persistent pollutants. In this study, we investigated their degradation by natural manganese peroxidase (nMnP) derived from Phanerochaete chrysosporium and recombinant manganese peroxidase packaged in vaults (vMnP). Encapsulation of manganese peroxidase (MnP) in ribonucleoprotein nanoparticle cages, called vaults, was achieved by creating recombinant vaults in yeast Pichia pastoris. Vault packaging increased the stability of MnP by locally sequestering multiple copies of the enzyme. Within 96 h, both vMnP and nMnP catalyzed over 72% removal of ANT in-vitro, which indicates that vault packaging did not limit substrate diffusion. It was observed that vMnP was more efficient than nMnP and P. chrysosporium for the catalysis of target contaminants. Only 57% of ANT was degraded by P. chrysosporium even when MnP activity reached about 480 U L
-1 in cultures. At 1.5 U L-1 initial activity, vMnP achieved 38% of ANT and 51% of DAT degradation, whereas even 2.7 times higher activity of nMnP showed insignificant biodegradation of both compounds. These results imply that due to protection by vault cages, vMnP has lower inactivation rates. Thus, it works effectively at lower dosage for a longer duration compared to nMnP without requiring frequent replenishment. Collectively, these results indicate that fungal enzymes packaged in vault nanoparticles are more stable and active, and they would be effective in biodegradation of energetic compounds in industrial processes, waste treatment, and contaminated environments., (Copyright © 2019 Elsevier Ltd.

- Abstract
Background: Acute ST elevation myocardial infarction (STEMI) is a medical emergency and is most commonly due to atherosclerotic plaque rupture and occlusion of coronary vessels. This case demonstrates that eosinophilic granulomatosis with polyangiitis (EGPA) myocarditis can mimic acute STEMI., Case Summary: A 44-year-old woman presented with acute chest pain, shortness of breath, and collapse with ST elevation on electrocardiography. Coronary angiogram showed unobstructed coronaries and chest film revealed left-sided consolidation. Together with a thorough history, serum eosinophilia, cardiac magnetic resonance (CMR), and computated tomography imaging, the patient was diagnosed with acute EGPA myocarditis. She responded tremendously to steroid and cyclophosphamide immunosuppression and subsequent CMR imaging demonstrated complete resolution of myocarditis., Discussion: CMR played a crucial role in the diagnosis and follow-up of this rare presentation. In patients who present as a STEMI but show unobstructed coronary vessels, EGPA may be a possible diagnosis., (© The Author(s) 2019.

- Abstract
Aims: The public reporting of healthcare outcomes has a number of potential benefits; however, unintended consequences may limit its effectiveness as a quality improvement process. We aimed to assess whether the introduction of individual operator specific outcome reporting after percutaneous coronary intervention (PCI) in the UK was associated with a change in patient risk factor profiles, procedural management, or 30-day mortality outcomes in a large cohort of consecutive patients., Methods and Results: This was an observational cohort study of 123 780 consecutive PCI procedures from the Pan-London (UK) PCI registry, from January 2005 to December 2015. Outcomes were compared pre- (2005-11) and post- (2011-15) public reporting including the use of an interrupted time series analysis. Patients treated after public reporting was introduced were older and had more complex medical problems. Despite this, reported in-hospital major adverse cardiovascular and cerebrovascular events rates were significantly lower after the introduction of public reporting (2.3 vs. 2.7%, P < 0.0001). Interrupted time series analysis demonstrated evidence of a reduction in 30-day mortality rates after the introduction of public reporting, which was over and above the existing trend in mortality before the introduction of public outcome reporting (35% decrease relative risk 0.64, 95% confidence interval 0.55-0.77; P < 0.0001)., Conclusion: The introduction of public reporting has been associated with an improvement in outcomes after PCI in this data set, without evidence of risk-averse behaviour. However, the lower reported complication rates might suggest a change in operator behaviour and decision-making confirming the need for continued surveillance of the impact of public reporting on outcomes and operator behaviour., (Published on behalf of the European Society of Cardiology.

- Abstract
Background: A large proportion of patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) present with multivessel disease (MVD). There is uncertainty in the role of complete coronary revascularization in this group of patients., Objectives: The aim of this study was to investigate the outcomes of complete revascularization compared with culprit vessel-only intervention in a large contemporary cohort of patients undergoing percutaneous coronary intervention (PCI) for NSTEMI., Methods: The authors undertook an observational cohort study of 37,491 NSTEMI patients treated between 2005 and 2015 at the 8 heart attack centers in London. Clinical details were recorded at the time of the procedure into local databases using the British Cardiac Intervention Society (BCIS) PCI dataset. A total of 21,857 patients (58.3%) presented with NSTEMI and MVD. Primary outcome was all-cause mortality at a median follow-up of 4.1 years (interquartile range: 2.2 to 5.8 years)., Results: A total of 11,737 (53.7%) patients underwent single-stage complete revascularization during PCI for NSTEMI, rates that significantly increased during the study period (p = 0.006). Those patients undergoing complete revascularization were older and more likely to be male, diabetic, have renal disease and a history of previous myocardial infarction/revascularization compared with the culprit-only revascularization group. Although crude, in-hospital major adverse cardiac event rates were similar (5.2% vs. 4.8%; p = 0.462) between the 2 groups. Kaplan-Meier analysis demonstrated significant differences in mortality rates between the 2 groups (22.5% complete revascularization vs. 25.9% culprit vessel intervention; p = 0.0005) during the follow-up period. After multivariate Cox analysis (hazard ratio: 0.90; 95% confidence interval: 0.85 to 0.97) and the use of propensity matching (hazard ratio: 0.89; 95% confidence interval: 0.76 to 0.98) complete revascularization was associated with reduced mortality., Conclusions: In NSTEMI patients with MVD, despite higher initial (in-hospital) mortality rates, single-stage complete coronary revascularization appears to be superior to culprit-only vessel PCI in terms of long-term mortality rates. This supports the need for further randomized study to confirm these findings., (Copyright © 2018 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Cardiogenic shock remains a major cause of morbidity and mortality in patients with ST-segment elevation myocardial infarction. We aimed to assess the current trends in cardiogenic shock management, looking specifically at the incidence, use of intra-aortic balloon pump therapy and outcomes in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention., Methods and Results: We undertook an observational cohort study of 21,210 ST-segment elevation myocardial infarction patients treated between 2005-2015 at the eight Heart Attack Centres in London, UK. Patients' details were recorded at the time of the procedure into local databases using the British Cardiac Intervention Society percutaneous coronary intervention dataset. There were 1890 patients who presented with cardiogenic shock. The primary outcome was all-cause mortality at a median follow-up of 4.1 years (interquartile range: 2.2-5.8 years). Increasing rates of cardiogenic shock were seen over the course of the study with consistently high mortality rates of 45-70%. A total of 685 patients underwent intra-aortic balloon pump insertion during primary percutaneous coronary intervention for cardiogenic shock with decreasing rates over time. Those patients undergoing intra-aortic balloon pump therapy were younger, more likely to have poor left ventricular function and less likely to have had previous percutaneous coronary intervention compared to the control group. Procedural success rates were similar (86.0% vs 87.1%, p=0.292) although crude, in-hospital major adverse cardiac event rates were higher (43.8% vs 33.7%, p<0.0001) in patients undergoing intra-aortic balloon pump therapy. Kaplan-Meier analysis demonstrated significantly higher mortality rates in patients receiving intra-aortic balloon pump therapy (50.9% intra-aortic balloon pump vs 39.9% control, p<0.0001) during the follow-up period. After multivariate Cox analysis (hazard ratio 1.04, 95% confidence interval 0.62-1.89) and the use of propensity matching (hazard ratio: 1.29, 95% confidence interval: 0.68-1.45) intra-aortic balloon pump therapy was not associated with mortality., Conclusion: Cardiogenic shock treated by percutaneous coronary intervention is increasing in incidence and remains a condition associated with high mortality and limited treatment options. Intra-aortic balloon pump therapy was not associated with a long-term survival benefit in this cohort and may be associated with increased early morbidity.

- Abstract
Objectives: The authors present the UK and Irish real-world learning curve experience of the Evolut R transcatheter heart valve., Background: The Evolut R is a self-expanding, repositionable, and fully recapturable second-generation transcatheter heart valve with several novel design features to improve outcomes and reduce complications., Methods: Clinical, procedural, and 30-day outcome data were prospectively collected for the first 264 patients to receive the Evolut R valve in the United Kingdom and Ireland., Results: A total of 264 consecutive Evolut R implantations were performed across 9 centers. The mean age was 81.1 ± 7.8 years, and the mean logistic European System for Cardiac Operative Risk Evaluation score was 19.9 ± 13.7%. Procedural indications included aortic stenosis (72.0%), mixed aortic valve disease (17.4%), and failing aortic valve bioprostheses (10.6%). Conscious sedation was used in 39.8% of patients and transfemoral access in 93.6%. The procedural success rate was 91.3%, and paravalvular leak immediately after implantation was mild or less in 92.3%. Major complications were rare: cardiac tamponade in 0.4%, conversion to sternotomy in 0.8%, annular rupture in 0.0%, coronary occlusion in 0.8%, major vascular in 5.3%, acute kidney injury in 6.1%, new permanent pacemaker implantation in 14.7%, and procedure-related death in 0.0%. At 30-day follow-up, survival was 97.7%, paravalvular leak was mild or less in 92.3%, and the stroke rate was 3.8%., Conclusions: This registry represents the largest published real-world experience of the Evolut R valve. The procedural success rate was high and safety was excellent, comparable with previous studies of the Evolut R valve and other second-generation devices. The low rate of complications represents an improvement on first-generation devices., (Copyright © 2017 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: ST-segment elevation myocardial infarction is increasingly common in octogenarians, and optimal management in this cohort is uncertain. This study aimed to describe the outcomes of octogenarians with ST-segment elevation myocardial infarction treated by primary percutaneous coronary intervention., Methods and Results: We analyzed 10 249 consecutive patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention between 2005 and 2011 at 8 tertiary cardiac centers across London, United Kingdom. The primary end point was all-cause mortality at a median follow-up of 3 years. In total, 1051 patients (10.3%) were octogenarians, with an average age of 84.2 years, and the proportion increased over the study period (P=0.04). In-hospital mortality (7.7% vs 2.4%, P<0.0001) and long-term mortality (51.6% vs 12.8%, P<0.0001) were increased in octogenarians compared with patients aged <80 years, and age was an independent predictor of mortality in a fully adjusted model (hazard ratio 1.07, 95% CI 1.07-1.09, P<0.0001). Time-stratified analysis revealed an increasingly elderly and more complex cohort over time. Nonetheless, long-term mortality rates among octogenarians remained static over time, and this may be attributable to improved percutaneous coronary intervention techniques, including significantly higher rates of radial access and lower bleeding complications. Variables associated with bleeding complications were similar between octogenarian and younger cohorts., Conclusions: In this large registry, octogenarians undergoing primary percutaneous coronary intervention had a higher rate of complications and mortality compared with a younger population. Over time, octogenarians undergoing primary percutaneous coronary intervention increased in number, age, and complexity. Nevertheless, in-hospital outcomes were reasonable, and long-term mortality rates were static., (© 2016 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.)

- Abstract
Objectives: This study aimed to assess the impact of thrombus aspiration on mortality in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI)., Background: The clinical effect of routine intracoronary thrombus aspiration before primary PCI in patients with ST-segment elevation myocardial infarction is uncertain., Methods: We undertook an observational cohort study of 10,929 ST-segment elevation myocardial infarction patients from January 2005 to July 2011 at 8 centers across London, United Kingdom. Patients' details were recorded at the time of the procedure into local databases using the British Cardiac Intervention Society PCI dataset. Primary outcome was all-cause mortality at a median follow-up of 3.0 years (interquartile range: 1.2 to 4.6 years)., Results: In our cohort, 3,572 patients (32.7%) underwent thrombus aspiration during primary PCI. Patients who had thrombus aspiration were younger, had lower rates of previous myocardial infarction but were more likely to have poor left ventricular function. Procedural success rates were higher (90.9% vs. 89.2%; p=0.005) and in-hospital major adverse cardiac event rates were lower (4.4% vs. 5.5%; p=0.012) in patients undergoing thrombus aspiration. However, Kaplan-Meier analysis demonstrated no significant difference in mortality rates between patients with and without thrombus aspiration (14.8% aspiration vs. 15.3% PCI only; p=0.737) during the follow-up period. After multivariate Cox analysis (hazard ratio [HR]: 0.89, 95% confidence interval [CI]: 0.65 to 1.23) and the addition of propensity matching (HR: 0.85 95% CI: 0.60 to 1.20) thrombus aspiration was still not associated with decreased mortality., Conclusions: In this cohort of nearly 11,000 patients, routine thrombus aspiration was not associated with a reduction in long-term mortality in patients undergoing primary PCI, although procedural success and in-hospital major adverse cardiac event rates were improved., (Copyright © 2015 American College of Cardiology Foundation.

Background & Aims: Ventricular assist devices (VADs) are used to treat patients with end-stage heart disease. However, patients with VADs frequently develop gastrointestinal (GI) bleeding. We investigated the incidence, etiology, and outcome of GI bleeding in patients with VADs., Methods: In a retrospective study, we analyzed data from 391 consecutive patients (mean age, 53.9 ± 14.2 years; 81% male) who underwent VAD implantation for end-stage heart disease from January 2000 through May 2012 at the Cleveland Clinic. Multivariable logistic regression analysis was used to identify factors independently associated with GI bleeding in patients with VADs., Results: Sixty-two patients (15.9%) had GI bleeding. The risk of GI bleeding increased by 10% for every 5-year increase in age (P = .006). GI bleeding was also associated with lower body mass index (P = .046), current smoking (P = .007), and lower baseline levels of hemoglobin (P < .001). Bleeding was primarily overt (79%), and most patients presented with hematochezia (43.5%). Causes of bleeding were primarily vascular malformations (26.5%) and ulcers (26.5%). Patients who received VADs as their only therapy, rather than as a bridge-to-transplantation, were more likely to have GI bleeding (P = .008). Colonoscopy detected GI bleeding with the highest diagnostic yield; most bleeding was associated with colonic lesions (51.4%). Overall mortality was 39.4%, and 2 deaths were directly related to GI bleeding., Conclusions: On the basis of a large case series analysis, GI bleeding is common after implantation of VADs (15.9% of patients have at least 1 episode of bleeding). Episodes were mostly overt and predominantly from the lower GI tract; colonoscopy is the best method of detection., (Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.)

- Abstract
Vascular calcification is an active and regulated process which is integral to cardiovascular disease and intimately linked to hypertension. Dysfunctional vascular smooth muscle cells, microvesicles, and dysregulated mineralization inhibitors play key roles in the calcification process, which occurs in the vessel intima in association with atherosclerosis as well as in the vessel media during ageing. Historically hypertension was considered a risk factor promoting atherosclerosis and associated intimal calcification. However, it is now recognized that not all vascular calcification occurs with atherosclerosis, and calcification of the vessel media is associated with arterial stiffening and is a major cause of isolated systolic hypertension in the elderly. Importantly, vascular calcification, regardless of its anatomical site, is an independent risk factor for cardiovascular mortality. Therefore, understanding the factors and mechanisms driving these processes will provide novel therapeutic targets for its prevention and perhaps ultimately its regression.
