RESUMO
BACKGROUND: Despite a temporal increase in respiratory failure in patients hospitalized with acute heart failure (HF), clinical trials have largely not reported the incidence or associated clinical outcomes for patients requiring mechanical ventilation. METHODS AND RESULTS: After pooling 5 acute HF clinical trials, we used multivariable logistic regression adjusted for demographics, comorbidities, examinations, and laboratory findings to assess associations between mechanical ventilation and clinical outcomes. Among the 8296 patients, 210 (2.5%) required mechanical ventilation. Age, sex, smoking history, baseline ejection fraction, HF etiology, and the proportion of patients randomized to treatment or placebo in the original clinical trial were similar between groups (all, P > 0.05). Baseline diabetes mellitus was more common in the mechanical ventilation group (Pâ¯=â¯0.02), but other comorbidities, including chronic lung disease, were otherwise similar (all P > 0.05). HF rehospitalization at 30 days (12.7% vs 6.6%, P < 0.001) and all-cause 60-day mortality (33.3% vs 6.1%, P < 0.001) was higher among patients requiring mechanical ventilation. After multivariable adjustment, mechanical ventilation use was associated with an increased 30-day HF rehospitalization (odds ratio 2.03; 95% confidence interval, 1.29-3.21, Pâ¯=â¯0.002), 30-day mortality (odds ratio 10.40; 95% confidence interval, 7.22-14.98, P < 0.001), and 60-day mortality (odds ratio 7.68; 95% confidence interval, 5.50-10.74, P < 0.001). The influence of mechanical ventilation did not differ by HF etiology or baseline ejection fraction (both, interaction P > 0.20). CONCLUSIONS: Respiratory failure during an index hospitalization for acute HF was associated with increased rehospitalization and all-cause mortality. The development of respiratory failure during an acute HF admission identifies a particularly vulnerable population, which should be identified for closer monitoring.

BACKGROUND: Ranolazine is approved in the United States and Europe for chronic stable angina. Microvascular angina (MVA) is defined as angina with no obstructive coronary artery disease. STUDY QUESTION: Our objective was to assess the effectiveness of ranolazine at improving angina scores and quality of life in a Canadian cohort with severe refractory angina due to MVA. STUDY DESIGN: We administered questionnaires to 31 patients at baseline and after at least 6 weeks of ranolazine treatment. MEASURES AND OUTCOMES: Validated, clinically significant changes for each Seattle Angina Questionnaire domain and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form were obtained from the literature. Score changes between baseline and postranolazine use were analyzed using sign test. RESULTS: Patients were mostly female (27 of 31 patients) with a median age of 57 years. After initiation of ranolazine treatment, patients experienced improvements in Quality of Life Enjoyment and Satisfaction Questionnaire Short Form scores (80.6%; P < 0.01) and in 3 of the 4 domains of the Seattle Angina Questionnaire (physical limitation: 73.3%; P = 0.02; treatment satisfaction: 80.6%; P < 0.01; and disease perception: 77.4%; P < 0.01). Patients were less likely to have interactions with the health care system after ranolazine treatment as compared with before (35.5% vs. 93.5%; P < 0.01). CONCLUSIONS: Ranolazine significantly improves symptom control and quality of life in patients with MVA and severe refractory angina and reduces their interaction with the health care system. Given the potentially debilitating effect of chronic angina in MVA, ranolazine may be an effective treatment option.

PURPOSE OF REVIEW: We provide a concise review of recent studies focusing on the management of patients with acute heart failure (AHF). RECENT FINDINGS: In well designed randomized trials, no mortality benefit has been observed with the use of diuretics, ultrafiltration, inotropes and vasodilators in AHF. Recent trials examining the role of novel inotropes and vasodilators as well as the role of mineralocorticoid receptor antagonists in the AHF population, is reviewed. SUMMARY: The focus of therapy in AHF should be directed towards symptom management. No mortality benefit has been observed despite good quality studies.

Formation of an intramural left atrial hematoma (ILAH) is a rare complication of coronary artery stenting. Rapid diagnosis with noninvasive multimodality imaging can potentially be lifesaving. We report a case of ILAH that resulted in left ventricular inflow obstruction and pericardial tamponade in a 55-year-old male who presented with hemodynamic instability and worsening dyspnea three weeks after seemingly uncomplicated left circumflex artery stenting. We demonstrate features on transthoracic echocardiography with contrast and cardiac computed tomography that were used for diagnosis and management.

Survival to hospital discharge among patients with out-of-hospital cardiac arrest (OHCA) is low and important regional differences in treatment practices and survival have been described. Since the 2017 publication of the Canadian Cardiovascular Society's position statement on OHCA care, multiple randomized controlled trials have helped to better define optimal post cardiac arrest care. This working group provides updated guidance on the timing of cardiac catheterization in patients with ST-elevation and without ST-segment elevation, on a revised temperature control strategy targeting normothermia instead of hypothermia, blood pressure, oxygenation, and ventilation parameters, and on the treatment of rhythmic and periodic electroencephalography patterns in patients with a resuscitated OHCA. In addition, prehospital trials have helped craft new expert opinions on antiarrhythmic strategies (amiodarone or lidocaine) and outline the potential role for double sequential defibrillation in patients with refractory cardiac arrest when equipment and training is available. Finally, we advocate for regionalized OHCA care systems with admissions to a hospital capable of integrating their post OHCA care with comprehensive on-site cardiovascular services and provide guidance on the potential role of extracorporeal cardiopulmonary resuscitation in patients with refractory cardiac arrest. We believe that knowledge translation through national harmonization and adoption of contemporary best practices has the potential to improve survival and functional outcomes in the OHCA population.

Background: Extracorporeal life support (ECLS) is associated with high morbidity and mortality. Complications and mortality are higher at lower-volume centres. Most Canadian ECLS institutions are low-volume centres. Protocols offer one way to share best practices among institutions to improve outcomes. Whether Canadian centres have ECLS protocols, and whether these protocols are comprehensive and homogenous across centres, is unknown. Methods: Purposeful sampling with mixed methods was used. A Delphi panel defined key elements relevant to the ECLS process. Documentation used in the delivery of ECLS services was requested from programs. Institutional protocols were assessed using deductive coding to determine the presence of key elements. Results: A total of 37 key elements spanning 5 domains (referral, initiation, maintenance, termination, and administration) were identified. Documentation from 13 institutions across 10 provinces was obtained. Institutions with heart or lung transplantation programs had more-complete documentation than did non-transplantation programs. Only 5 key elements were present in at least 50% of protocols (anticoagulation strategy, ventilation strategy, defined referral process, selection criteria, weaning process), and variation was seen in how institutions approached each of these elements. Conclusions: The completeness of ECLS protocols varies across Canada. Programs describe variable approaches to key elements. This variability might represent a lack of evidence or consensus in these areas and creates the opportunity for collaboration among institutions to share protocols and best practice. The key-element framework provides a common language that programs can use to develop ECLS programs, initiate quality-improvement projects, and identify research agendas.
Introduction: L'assistance cardiorespiratoire extracorporelle (ACRE) est associée à des taux élevés de morbidité et de mortalité. Les taux de complications et de mortalité sont plus élevés dans les centres à volume plus faible. La plupart des établissements qui offrent l'ACRE au Canada sont des centres à volume faible. Les protocoles constituent un moyen de partager des pratiques exemplaires entre les établissements afin d'améliorer les résultats. On ignore si les centres du Canada ont des protocoles d'ACRE, et si ces protocoles sont exhaustifs et homogènes dans tous les centres. Méthodes: Nous avons utilisé un échantillonnage dirigé par méthodes mixtes. Le panel Delphi a défini les éléments fondamentaux pertinents au processus d'ACRE. La documentation utilisée pour la prestation de services d'ACRE a été demandée aux programmes. Nous avons évalué les protocoles des établissements au moyen du processus inductif de codification pour déterminer la présence d'éléments fondamentaux. Résultats: Nous avons relevé un total de 37 éléments fondamentaux couvrant cinq domaines (aiguillage, amorce, maintien, cessation et administration). La documentation provenait de 13 établissements de 10 provinces. Les établissements qui ont des programmes de transplantation cardiaque ou pulmonaire avaient une documentation plus complète que les programmes sans transplantation. Seuls cinq éléments fondamentaux étaient présents dans au moins 50 % des protocoles (stratégie d'anticoagulation, stratégie de ventilation, processus défini d'aiguillage, critères de sélection, processus de sevrage), et une variation était observée dans la façon dont les établissements considéraient chacun de ces éléments. Conclusions: Au Canada, l'exhaustivité des protocoles d'ACRE varie. Les programmes décrivent la variabilité des approches des éléments fondamentaux. Cette variabilité qui pourrait représenter le manque de données probantes ou de consensus dans ces domaines ouvre la voie à la collaboration des établissements au partage des protocoles et des pratiques exemplaires. Le cadre des éléments fondamentaux contribue à offrir un langage commun que peuvent utiliser les programmes pour élaborer des programmes d'ACRE, amorcer des projets d'amélioration de la qualité et établir des programmes de recherche.
RESUMO
Family engagement empowers family members to become active partners in care delivery. Family members increasingly expect and wish to participate in care and be involved in the decision-making process. The goal of engaging families in care is to improve the care experience to achieve better outcomes for both patients and family members. There is emerging evidence that engaging family members in care improves person- and family-important outcomes. Engaging families in adult cardiovascular care involves a paradigm shift in the current organization and delivery of both acute and chronic cardiac care. Many cardiovascular health care professionals have limited awareness of the role and potential benefits of family engagement in care. Additionally, many fail to identify opportunities to engage family members. There is currently little guidance on family engagement in any aspect of cardiovascular care. The objective of this statement is to inform health care professionals and stakeholders about the importance of family engagement in cardiovascular care. This scientific statement will describe the rationale for engaging families in adult cardiovascular care, outline opportunities and challenges, highlight knowledge gaps, and provide suggestions to cardiovascular clinicians on how to integrate family members into the health care team.

BACKGROUND: Women with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention historically experience worse in-hospital outcomes compared to men. HYPOTHESIS: Implementation of a regional STEMI system will reduce care gaps in reperfusion times and in-hospital outcomes between women and men. METHODS: 1928 patients (413 women, 21.4%) presented with an acute STEMI between June 2007 and March 2016. The population was divided into an early cohort (n = 728 patients, 2007-May 2011), and a late cohort (n = 1200 patients, June 2011-2016). The primary endpoints evaluated were reperfusion times and in-hospital outcomes. RESULTS: Compared to men, women experienced significant delays in first medical contact (FMC) to arrival at the emergency room (26.0 vs. 22.0 min, p < 0.001) and FMC-to-device (109 vs. 101 min p = 0.001). Women had higher incidences of post-PCI heart failure and death compared to men (p < 0.05). Following multivariable adjustment, no mortality difference was observed for women versus men (adjusted OR; 0.82; 95% confidence interval [CI], 0.51-1.34; p = 0.433) or for early versus late cohorts (adjusted OR; 1.04; 95% CI, 0.68-1.60; p = 0.856). CONCLUSION: Following STEMI regionalization, women continued to experience significantly longer reperfusion times, although there was no difference in adjusted mortality. These results highlight the ongoing disparity of STEMI care between women and men, and suggest that regionalization alone is insufficient to close sex-based care gaps.

BACKGROUND: Treatment of ST-elevation myocardial infarction (STEMI) in Canada is protocolized, and timely patient transfer can improve outcomes. Population-based processes of care in Canada for other cardiovascular conditions remain less clear. We aimed to describe the interhospital transfer of Canadian patients with acute cardiovascular disease. METHODS: We reviewed the Canadian Institute for Health Information Discharge Abstract Database for adult patients hospitalized with acute cardiovascular disease between 2013 and 2018. We compared patient characteristics and clinical outcomes based on transfer status (transferred, nontransferred) and presenting hospital (teaching, large community, medium community, and small community hospitals). The primary outcome of interest was in-hospital mortality. RESULTS: There were 476,753 patients with primary acute cardiovascular diagnoses, 48,579 (10.2%) of whom were transferred. Transferred patients were more frequently younger, male, and had fewer comorbidities. The most common diagnoses among transferred patients were non-STEMI (44.2%), STEMI (29.0%), and congestive heart failure (9.4%). Using teaching hospitals as a reference, transfer to large and medium community hospitals was associated with lower hospital mortality (adjusted odds ratio: 0.83, 95% confidence interval: 0.75-0.91 and 0.45, 95% confidence interval: 0.39-0.52, respectively). CONCLUSIONS: Approximately 10% of patients with acute cardiovascular conditions are transferred to another hospital. Patient transfer may be associated with lower in-hospital mortality, with possible variability based on diagnosis, comorbidities, hospital of origin, and destination hospital. Further investigation into the optimization of care for patients with acute cardiovascular disease, including transfer practices, is warranted as regionalized care models continue to develop.
INTRODUCTION: Au Canada, le traitement de l'infarctus du myocarde avec sus-décalage du segment ST (STEMI) découle d'un protocole qui prévoit au moment opportun le transfert des patients pour permettre d'améliorer les résultats cliniques. On n'en sait encore peu sur les processus de soins auprès de la population canadienne en ce qui concerne les autres maladies cardiovasculaires. Nous avions pour objectif de décrire les transferts interhospitaliers de patients canadiens atteints d'une maladie cardiovasculaire aiguë. MÉTHODES: Nous avons passé en revue les résumés de la base de données de l'Institut canadien d'information sur la santé sur les congés des patients hospitalisés atteints d'une maladie cardiovasculaire aiguë entre 2013 et 2018. Nous avons comparé les caractéristiques des patients et les résultats cliniques en fonction du statut du transfert (patients transférés ou non transférés) et de l'hôpital de destination (hôpitaux d'enseignement, grands hôpitaux communautaires, hôpitaux communautaires moyens et petits hôpitaux communautaires). Le principal critère étudié était la mortalité intrahospitalière. RÉSULTATS: Parmi les 476 753 patients qui avaient un diagnostic principal de maladie cardiovasculaire aiguë, 48 579 (10,2 %) ont été transférés. Les patients transférés étaient plus fréquemment jeunes, de sexe masculin, et avaient peu de comorbidités. Les diagnostics les plus fréquents parmi les patients transférés étaient les non-STEMI (44,2 %), les STEMI (29,0 %) et l'insuffisance cardiaque congestive (9,4 %). En utilisant comme référence les hôpitaux d'enseignement, les transferts vers de grands hôpitaux communautaires et des hôpitaux communautaires moyens étaient associés à une plus faible mortalité intrahospitalière (ratio d'incidence approché ajusté : 0,83, intervalle de confiance à 95 %, 0,75-0,91 et 0,45, intervalle de confiance à 95 %, 0,39-0,52, et ce, respectivement). CONCLUSIONS: Approximativement 10 % des patients atteints d'une maladie cardiovasculaire aiguë sont transférés vers un autre hôpital. Le transfert des patients peut être associé à une plus faible mortalité intrahospitalière et montrer une variabilité en fonction du diagnostic, des comorbidités, de l'hôpital d'origine et de l'hôpital de destination. D'autres études liées à l'optimisation des soins des patients atteints d'une maladie cardiovasculaire aiguë, qui porteront de plus sur les pratiques de transfert, sont justifiées puisque l'élaboration de modèles de soins régionaux se poursuit.
RESUMO
The ongoing COVID-19 pandemic has placed pressure on health care systems and intensive care unit capacity worldwide. Respiratory insufficiency is the most common reason for hospital admission in patients with COVID-19. The most severe form of respiratory failure is acute respiratory distress syndrome (ARDS), which is associated with significant morbidity and mortality. Patients with ARDS are often treated with invasive mechanical ventilation according to established evidence-based and guideline recommended management strategies. With growing strain on critical care capacity, clinicians from diverse backgrounds, including cardiovascular specialists, might be required to help care for the growing number of patients with severe respiratory failure and ARDS. The aim of this article is to outline the fundamentals of ARDS diagnosis and management, including mechanical ventilation, for the nonintensivist. In the absence of mechanical ventilation trials specifically in patients with COVID-19-associated ARDS, the information presented is on the basis of general ARDS trials.

Coronary artery disease (CAD) is the most prevalent type of heart disease among women and men. Sex-related differences in the presentation, prognosis, and management of patients with CAD has been increasingly studied. Compared with men, women are more likely to present with multiple comorbidities, have a higher prevalence of psychological risk factors, and present with atypical symptoms. These factors, along with delays in seeking medical attention, might contribute to sex-related treatment differences in women with stable angina and acute coronary syndrome. This review article highlights recent evidence examining sex-related differences in stable CAD patients with obstructive CAD, nonobstructive CAD, as well as myocardial infarction.

Kounis syndrome is defined as an acute coronary syndrome triggered by allergic or hypersensitivity reactions resulting in mast cell and platelet activation. Numerous causes have been described, including various drugs, medical conditions, and environmental exposures. Samter's triad consists of nasal polyps, asthma, and aspirin (or nonsteroidal anti-inflammatory drug) sensitivity. We describe a case of Kounis type I in a young woman with Samter's triad who presented with cardiac arrest on 3 occasions. Ergonovine provocation testing established the diagnosis of coronary vasospasm. The patient has derived significant benefit from calcium channel blockers.

AIM: To compare low volume polyethylene glycol with ascorbic acid, sodium picosulfate-magnesium citrate and clear liquid diet alone as bowel preparation prior to small bowel capsule endoscopy (CE). METHODS: We retrospectively collected all CE studies done from December 2011 to July 2013 at a single institution. CE studies were reviewed only if low volume polyethylene glycol with ascorbic acid, sodium picosulfate-magnesium citrate or clear liquid diet alone used as the bowel preparation. The studies were then reviewed by the CE readers who were blinded to the preparation type. Cleanliness and bubble burden were graded independently within the proximal, middle and distal small bowel using a four-point scale according to the percentage of small bowel mucosa free of debris/bubbles: grade 1 = over 90%, grade 2 = between 90%-75%, grade 3 = between 50%-75%, grade 4 = less than 50%. Data are expressed as mean ± SEM. ANOVA and Fishers exact test were used where appropriate. P values < 0.05 were considered statistically significant. RESULTS: A of total of 123 CE studies were reviewed. Twenty-six studies were excluded from analysis because of incomplete small bowel examination. In the remaining studies, 39 patients took low volume polyethylene glycol with ascorbic acid, 31 took sodium picosulfate-magnesium citrate and 27 took a clear liquid diet alone after lunch on the day before CE, followed by overnight fasting in all groups. There was no significant difference in small bowel cleanliness (1.98 ± 0.09 vs 1.84 ± 0.08 vs 1.76 ± 0.08) or small bowel transit time (213 ± 13 vs 248 ± 14 ± 225 ± 19 min) for clear liquid diet alone, MoviPrep and Pico-Salax respectively. The bubble burden in the mid small bowel was significantly higher in the MoviPrep group (1.6 ± 0.1 vs 1.9 ± 0.1 vs 1.6 ± 0.1, P < 0.05). However this did not result in a significant difference in diagnosis of pathology. CONCLUSION: There was no significant difference in small bowel cleanliness or diagnostic yield of small bowel CE between the three preparations regimens used in this study.
RESUMO
Specialized endoscopic evaluation for patients with Barrett's esophagus (BE) is well supported; however, no studies have shown that centers with expertise provide better quality care for BE with high-grade dysplasia or early adenocarcinoma. In this study, the investigators aimed to evaluate the management and clinical course for patients treated in a community practice versus a specialized BE center. Methods. A retrospective analysis of referrals from the community to our specialized center for evaluation of BE at St Paul's Hospital Division of Gastroenterology between January 2007 and February 2014 was performed. Subjects were patients who were referred for BE and dysplasia and subsequently reevaluated by endoscopy. The pathology and endoscopy reports from the community and our center were reviewed. Inclusion criteria were as follows: being ≥ 19 years old and pathologic diagnosis of BE or dysplasia in the community. Exclusion criteria were as follows: incomplete pathology data or incomplete endoscopy reports from the community physicians. Results. A total of 77 patients were reviewed. The staging of 28.9% of patients referred from the community was changed from the initial pathological diagnosis. 18.4% of these patients were upstaged. Using Fischer's exact test, we showed that, in our specialized center, endoscopic impressions correlated significantly with pathology results (p < 0.0001).

Helicobacter pylori (H. pylori) infection has been clearly linked to peptic ulcer disease and some gastrointestinal malignancies. Increasing evidence demonstrates possible associations to disease states in other organ systems, known as the extraintestinal manifestations of H. pylori. Different conditions associated with H. pylori infection include those from hematologic, cardiopulmonary, metabolic, neurologic, and dermatologic systems. The aim of this article is to provide a concise review of the evidence that supports or refutes the associations of H. pylori and its proposed extraintestinal manifestations. Based on data from the literature, PUD, mucosal associated lymphoid tumors lymphoma, and gastric adenocarcinoma has well-established links. Current evidence most supports extraintestinal manifestations with H. pylori in immune thrombocytopenic purpura, iron deficiency anemia, urticaria, Parkinson's, migraines and rosacea; however, there is still plausible link with other diseases that requires further research.
