Evaluation of Guideline-Directed Medical Therapy for Outpatients Living with Heart Failure with Reduced Ejection Fraction.

Background: Pharmacotherapy is the cornerstone of treatment for heart failure with reduced ejection fraction (HFrEF). The Canadian Cardiovascular Society and Canadian Heart Failure Society have defined guideline-directed medical therapy (GDMT) as 4 foundational medications. Despite strong recommendations for use of GDMT in HFrEF, current practice alignment with guidelines is unknown. Objectives: The primary objectives were to determine the proportion of patients for whom optimized GDMT for HFrEF was prescribed, to describe the doses of foundational medications achieved, and to describe any documented rationale limiting the optimization of GDMT. The secondary objectives were to describe documented pharmacist activities outside of scheduled multidisciplinary appointments at the heart function clinic (HFC) and to describe heart failure-related hospital encounters in 2021. Methods: A retrospective cohort study using medical records of patients with HFrEF who were receiving treatment at the Regina HFC as of December 31, 2021, was conducted. Results: Of the 129 patients included in the study, 61 (47.3%) were prescribed optimized GDMT. Specifically, within the individual foundational medication classes, 82.2% (106/129), 80.6% (104/129), 79.1% (102/129), and 74.4% (96/129) of patients received optimized therapy with a renin-angiotensin system inhibitor, mineralocorticoid receptor antagonist, ß-blocker, and sodium-glucose cotransporter 2 inhibitor, respectively. Documented rationale was not available in 35.8% (38/106) of instances of suboptimal utilization of GDMT and in 41.7% (60/144) of instances of suboptimal dosing of GDMT. The most common documented rationale for suboptimal utilization was intolerance to the medication (33.0% [35/106]), and the most common rationale for suboptimal dosing was intolerance to dose increases (57.6% [83/144]). Pharmacists documented a total of 553 patient care activities for 58.9% (76/129) of the patients, outside scheduled multidisciplinary appointments in the HFC. Sixteen patients (12.4%) had heart failure-related hospital encounters a total of 31 times in 2021. Conclusions: Although many patients were receiving the benefits of multidisciplinary care at the Regina HFC, there remained a treatment gap in the use of GDMT for HFrEF. These findings will be used to inform strategies to improve clinic processes, including efficient identification of patients requiring optimization of GDMT, who would benefit the most from multidisciplinary care.

Contexte: La pharmacothérapie est la pierre angulaire du traitement de l'insuffisance cardiaque avec fraction d'éjection réduite (ICFEr). La Société cardiovasculaire du Canada et la Société canadienne d'insuffisance cardiaque ont défini le traitement médical fondé sur les lignes directrices (TMFLD) selon 4 médicaments fondamentaux. Malgré de fortes recommandations pour l'utilisation du TMFLD dans l'ICFEr, l'alignement actuel de la pratique sur les lignes directrices est inconnu. Objectifs: Les objectifs principaux étaient de déterminer la proportion de patients pour lesquels un TMFLD optimisé pour l'ICFEr avait été prescrit, de décrire les doses obtenues et de décrire les justifications documentées limitant l'optimisation du TMFLD. Les objectifs secondaires, quant à eux, étaient de décrire les activités documentées du pharmacien en dehors des rendez-vous prévus à la clinique multidisciplinaire de fonction cardiaque et de recenser les consultations hospitalières liées à l'insuffisance cardiaque au cours de l'année civile 2021. Méthodes: Cette étude de cohorte rétrospective se basait sur les dossiers médicaux de patients atteints d'ICFEr qui recevaient un traitement à la clinique de fonction cardiaque de Regina au 31 décembre 2021. Résultats: Sur les 129 patients inclus dans l'étude, 61 d'entre eux (47,3 %) ont reçu un TMFLD optimisé. Plus précisément, en ce qui concerne les classes de médicaments fondamentaux, 82,2 % (106/129) ont reçu un traitement optimal avec un inhibiteur du système rénine-angiotensine, 80,6 % (104/129) avec un antagoniste des récepteurs minéralocorticoïdes, 79,1 % (102/129) avec un ß-bloquant et 74,4 % (96/129) avec un inhibiteur sodique du cotransporteur de glucose 2. Dans 35,8 % (38/106) des cas d'utilisation sous-optimale du TMFLD et dans 41,7 % (60/144) des cas de dosage sous-optimal de celui-ci, la justification documentée était indisponible. Lorsqu'elles étaient documentées, les justifications les plus courantes étaient l'intolérance, respectivement, à l'utilisation d'un médicament (33.0% [35/106]) et à l'augmentation de la dose (57,6 % [83/144]). Les pharmaciens ont consigné un total de 553 activités de soins aux patients pour 58,9 % (76/129) des patients en dehors des rendez-vous multidisciplinaires prévus dans la clinique de fonction cardiaque. Seize (12,4 %) des patients ont été hospitalisés pour une insuffisance cardiaque 31 fois au total en 2021. Conclusion: Bien que de nombreux patients bénéficiaient des soins multidisciplinaires à la clinique de fonction cardiaque de Regina, une lacune subsistait dans le traitement par rapport à l'utilisation du TMFLD pour l'ICFEr. Ces résultats seront utilisés pour éclairer les stratégies visant à améliorer les processus cliniques, y compris l'identification efficace des patients nécessitant une optimisation du TMFLD, qui bénéficieraient le plus de soins multidisciplinaires.

2022 Canadian Cardiovascular Society Guideline for Use of GLP-1 Receptor Agonists and SGLT2 Inhibitors for Cardiorenal Risk Reduction in Adults.

This guideline synthesizes clinical trial data supporting the role of glucagon-like peptide-1 receptor agonists and sodium-glucose co-transporter 2 inhibitors (SGLT2i) for treatment of heart failure (HF), chronic kidney disease, and for optimizing prevention of cardiorenal morbidity and mortality in patients with type 2 diabetes. It is on the basis of a companion systematic review and meta-analysis guided by a focused set of population, intervention, control, and outcomes (PICO) questions that address priority cardiorenal end points. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system and a modified Delphi process were used. We encourage comprehensive assessment of cardiovascular (CV) patients with routine measurement of estimated glomerular filtration rate, urinary albumin-creatinine ratio, glycosylated hemoglobin (A1c), and documentation of left ventricular ejection fraction (LVEF) when evaluating symptoms of HF. For patients with HF, we recommend integration of SGLT2i with other guideline-directed pharmacotherapy for the reduction of hospitalization for HF when LVEF is > 40% and for the reduction of all-cause and CV mortality, hospitalization for HF, and renal protection when LVEF is ≤ 40%. In patients with albuminuric chronic kidney disease, we recommend integration of SGLT2i with other guideline-directed pharmacotherapy to reduce all-cause and CV mortality, nonfatal myocardial infarction, and hospitalization for HF. We provide recommendations and algorithms for the selection of glucagon-like peptide-1 receptor agonists and SGLT2i for patients with type 2 diabetes and either established atherosclerotic CV disease or risk factors for atherosclerotic CV disease to reduce all-cause and CV mortality, nonfatal stroke, and for the prevention of hospitalization for HF and decline in renal function. We offer practical advice for safe use of these diabetes-associated agents with profound cardiorenal benefits.

Prolonged methylene blue infusion in refractory septic shock: a case report.

PURPOSE: Methylene blue (MB) has been advocated for the treatment of refractory hemodynamic instability in patients with septic shock. However, the use of MB infusions in septic shock is not considered standard treatment, and the available literature describes infusions of short duration, typically less than six hours. CLINICAL FEATURES: We report a case of septic shock in a 67-yr-old male who required maximal vasopressor support with norepinephrine, epinephrine, and vasopressin. Despite standard protocols for the treatment of septic shock, the patient's hemodynamic status was refractory 80 hr post admission. However, initiation of a MB infusion resulted in the rapid restoration of hemodynamic stability and a subsequent decrease in vasopressor requirements. Multiple attempts to discontinue the MB infusion resulted in immediate and repeated increases in vasopressor requirements, necessitating a continuous infusion with a slow taper of MB for 120 hr. Ultimately, the patient survived the illness and was discharged home. We observed no adverse events that could be attributed to the use of MB. CONCLUSION: In our patient, the use of MB resulted in hemodynamic stability unattained with standard vasopressor support. Further research is warranted on the use of MB in patients with septic shock.

Impacts of the COVID-19 Pandemic on Cardiac Rehabilitation Delivery around the World.

Background: We investigated impacts of COVID-19 on cardiac rehabilitation (CR) delivery around the globe, including virtual delivery, as well as effects on providers and patients. Methods: In this cross-sectional study, a piloted survey was administered to CR programs globally via REDCap from April to June 2020. The 50 members of the International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) and personal contacts facilitated program identification. Results: Overall, 1062 (18.3% program response rate) responses were received from 70/111 (63.1% country response rate) countries in the world with existent CR programs. Of these, 367 (49.1%) programs reported they had stopped CR delivery, and 203 (27.1%) stopped temporarily (mean = 8.3 ± 2.8 weeks). Alternative models were delivered in 322 (39.7%) programs, primarily through low-tech modes (n = 226,19.3%). Furthermore, 353 (30.2%) respondents were re-deployed, and 276 (37.3%) felt the need to work due to fear of losing their job, despite the perceived risk of contracting COVID-19 (mean = 30.0% ± 27.4/100). Also, 266 (22.5%) reported anxiety, 241(20.4%) were concerned about exposing their family, 113 (9.7%) reported increased workload to transition to remote delivery, and 105 (9.0%) were juggling caregiving responsibilities during business hours. Patients were often contacting staff regarding grocery shopping for heart-healthy foods (n = 333, 28.4%), how to use technology to interact with the program (n = 329, 27.9%), having to stop their exercise because they have no place to exercise (n = 303, 25.7%), and their risk of death from COVID-19 due to pre-existing cardiovascular disease (n = 249, 21.2%). Respondents perceived staff (n = 488, 41.3%) and patient (n = 453, 38.6%) personal protective equipment, as well as COVID-19 screening (n = 414, 35.2%), and testing (n = 411, 35.0%) as paramount to in-person service resumption. Conclusion: Given the estimated number of CR programs globally, these results suggest approximately 4400 CR programs globally have ceased or temporarily stopped service delivery. Those that remain open are implementing new technologies to ensure their patients receive CR safely, despite the challenges. Highlights: - COVID-19 has impacted cardiac rehabilitation (CR) delivery around the globe.- In this cross-sectional study, a survey was completed by 1062 (18.3%) CR programs from 70 (63.1%) countries.- The pandemic has resulted in at least temporary cessation of ~75% of CR programs, with others ceasing initiation of new patients, reducing components delivered, and/or changing of mode delivery with little opportunity for planning and training.- There is also significant psychosocial and economic impact on CR providers.- Alternative CR model (e.g., home-based, virtual) reimbursement advocacy is needed, to ensure safe, accessible secondary prevention delivery.

Cardiac Rehabilitation for Women: A Systematic Review of Barriers and Solutions.

Cardiac rehabilitation (CR) services improve various clinical outcomes in patients with cardiovascular disease, but such services are underutilized, particularly in women. The aim of this study was to identify evidence-based barriers and solutions for CR participation in women. A literature search was carried out using PubMed, EMBASE, Cochrane, OVID/Medline, and CINAHL to identify studies that have assessed barriers and/or solutions to CR participation. Titles and abstracts were screened, and then the full-text of articles that met study criteria were reviewed. We identified 24 studies that studied barriers to CR participation in women and 31 studies that assessed the impact of various interventions to improve CR referral, enrollment, and/or completion of CR in women. Patient-level barriers included lower education level, multiple comorbid conditions, non-English native language, lack of social support, and high burden of family responsibilities. We found support for the use of automatic referral and assisted enrollment to improve CR participation. A small number of studies suggest that incentive-based strategies, as well as home-based programs, may contribute to improving CR attendance and completion rates. A systematic approach to CR referral, including automatic CR referral, may help overcome barriers to CR referral in women and should be implemented in clinical practice. However, more studies are needed to help identify the best methods to improve CR attendance and completion of CR rates in women.

Effectiveness of femoral nerve blockade for pain control after total knee arthroplasty.

Control of postoperative pain is a major concern for patients undergoing total knee arthroplasty (TKA). The purpose of this study was to investigate pain control and opioid use, as well as length of stay, ambulation time, antiemetic use, and degree of mobilization for patients undergoing total knee arthroplasty, comparing those receiving femoral nerve block (FNB) to those receiving no femoral nerve block. Using retrospective patient record data, 133 subjects from an acute care community hospital in western Canada were split into three groups: no FNB (control group, n = 49), single-shot FNB (n = 33), and continuous FNB (n = 51). There was a statistically significant improvement in pain control on day of surgery for the FNB group compared with the no-FNB group, and reduction in opioid usage on days 0, 1, and 2 in the continuous FNB group compared with the no-FNB and single-shot group. Also noted was a statistically significant reduction in antiemetic use in the FNB compared with the no-FNB group on the day after surgery. This study is in accordance with earlier studies that support continuous FNB as an effective method for achieving postoperative pain control and reducing opioid use for patients undergoing TKA.
