Characteristics, management, and outcomes in women and men with congestive heart failure in 40 countries at different economic levels: an analysis from the Global Congestive Heart Failure (G-CHF) registry. Lancet Glob Health 2024; 12:e396-e405. [PMID: 38218197 DOI: 10.1016/s2214-109x(23)00557-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 11/21/2023] [Accepted: 11/24/2023] [Indexed: 01/15/2024]
Abstract
BACKGROUND There is a paucity of data on the clinical characteristics, management, and outcomes of women compared with men with heart failure in low-income and middle-income countries compared with high-income countries. We examined sex differences in risk factors, clinical characteristics, and treatments, and prospectively assessed the risk of heart failure hospitalisation and mortality in patients with heart failure in 40 high-income, middle-income, and low-income countries. METHODS Participants aged 18 years or older with heart failure were enrolled from Dec 20, 2016, to Sept 9, 2020 in the prospective Global Congestive Heart Failure (G-CHF) study from 257 centres in 40 high-income, middle-income, and low-income countries. Participants were followed up until May 25, 2023. We recorded the demographic characteristics, medical history, and treatments of participants. We prospectively recorded data on heart failure hospitalisation and mortality by sex in the overall study, according to country economic status, and according to level of left ventricular ejection fraction (LVEF). FINDINGS 23 341 participants (9119 [39·1%] women and 14 222 [60·1%] men) were recruited and followed up for a mean of 2·6 years (SD 1·4). The mean age of women in the study was 62 years (SD 17) compared with 64 years (14) in men. Fewer women than men had an LVEF of 40% or lower (51·7% women vs 66·2% men). By contrast, more women than men had an LVEF of 50% or higher (33·2% women vs 18·6% men). Hypertensive heart failure was the most common aetiology in women (25·5% women vs 16·8% men), whereas ischaemic heart failure was the most common aetiology in men (45·6% men vs 26·6% women). Signs and symptoms of congestion were more common in women than men: 42·6% of women had a New York Heart Association functional class of III or IV compared with 37·9% of men. The use of heart failure medications and cardiac tests did not differ systematically between the sexes, although implantable cardioverter defibrillator (ICD) implantation was lower among women than men (8·7% women vs 17·2% men). The adjusted risk of heart failure hospitalisation was similar in women and men (women-to-men adjusted hazard ratio [HR] 0·99 [95% CI 0·92-1·05]). This pattern was consistent within groups of countries categorised by economic status, geographical region, and by LVEF level. However, women had a lower adjusted risk of mortality (women-to-men adjusted HR 0·79 [95% CI 0·75-0·84]) despite adjustments for prognostic factors-a pattern which was consistently observed across groups of countries irrespective of economic status, geography, and LVEF levels of patients. INTERPRETATION The underlying cause of heart failure and ejection fraction phenotype differ between women and men, as do the severity of symptoms. Heart failure treatments (except ICD use) were not consistently in favour of one sex. Paradoxically, while the rates of hospitalisations were similar among women and men, the risk of death was lower among women. These patterns were consistent regardless of the economic status of the countries. The higher mortality among men is unexplained and warrants further study. FUNDING Bayer.

Sex Differences in Systemic and Coronary Arterial Hemodynamics in Heart Failure With Preserved Ejection Fraction. Am J Cardiol 2023; 205:87-93. [PMID: 37595413 DOI: 10.1016/j.amjcard.2023.07.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 06/27/2023] [Accepted: 07/08/2023] [Indexed: 08/20/2023]
Abstract
Heart failure (HF) with preserved ejection fraction (HFpEF) predominantly affects females. Systemic and coronary arterial abnormalities are present in HFpEF and may contribute to HFpEF in females. We performed a cross-sectional study of 32 participants with HFpEF and 26 controls. Arterial hemodynamics were noninvasively assessed by combining arterial tonometry with echocardiography. Coronary microvascular function was assessed by rubidium-82 positron emission tomography as the myocardial flow reserve. Coronary vascular resistance (CVR) at rest and vasodilator stress were calculated using positron emission tomography. CVR reserve was calculated as stress - rest CVR. Multivariable linear regression assessed the associations of female sex with arterial hemodynamics in participants with and without HF, and the association of HF with arterial hemodynamics within each sex stratum. Demographics and left ventricular systolic and diastolic function were similar between males and females. Among those with HFpEF, females had a higher steady and pulsatile arterial load and more impaired (less negative) CVR reserve than males. Conversely, in controls, females had similar hemodynamics to males. We then divided the sample based on sex. Femaleswith HFpEF had a higher pulsatile arterial load and higher stress CVR than control females. Among males, arterial hemodynamics were similar, regardless of HFpEF status. The measures of early pulsatile arterial load were independently associated with higher E/e' and lower myocardial flow reserve in females only. In conclusion, despite similar left ventricular function between sexes, older females with HFpEF are characterized by additional systemic and coronary arterial hemodynamic abnormalities compared with males with HFpEF and similarly aged females without HFpEF.

Outcomes of acute heart failure patients managed in the emergency department. CAN J EMERG MED 2023; 25:752-760. [PMID: 37537320 DOI: 10.1007/s43678-023-00555-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 06/24/2023] [Indexed: 08/05/2023]
Abstract
BACKGROUND Acute heart failure is a serious condition commonly seen in the emergency department (ED). The HEARTRISK6 Scale has been recently developed to identify the risk of poor outcomes but has not been tested. We sought to describe the management and outcomes of ED patients with acute heart failure and to evaluate the potential impact of the HEARTRISK6 Scale. METHODS We conducted a health records review of 300 consecutive acute heart failure patients presenting to two tertiary care EDs. Two evaluators abstracted clinical variables, ED management and treatment details, and patient outcomes using the electronic health records platform (EPIC) and attending physicians verified the data. The primary outcome measure was a short-term serious outcome, as shown in Results. In addition, the HEARTRISK6 score was calculated retrospectively. RESULTS We included 300 patients with mean age of 78.5 years, 51.0% male, 56.3% arrival by ambulance, and 67.0% admitted to hospital. 25.3% experienced a short-term serious outcome 1) after admission (N = 201): non-invasive ventilation 14.9%, intubation 1.5%, major cardiac procedure 5.0%, myocardial infarction 2.0%, death 8.5%; 2) after ED discharge (N = 99): return to ED 21.2%, death 4.0%. Those initially admitted experienced a much higher proportion of serious outcomes compared to those discharged (29.9% vs. 16.2%). A HEARTRISK6 Scale cut-point score of ≥ 1 would have had a sensitivity of 91.0%, specificity 24.5%, and negative likelihood ratio 0.37 for short-term serious outcomes and suggested hospital admission for 80.7% of cases. CONCLUSION There was a large range of severity of illness of acute heart failure patients and a wide variety of treatments were administered in the ED. Both admitted and discharged patients experienced a high proportion of poor outcomes. The HEARTRISK6 Scale showed a high sensitivity for short-term serious outcomes but with the potential to increase hospital admissions. Further validation of the HEARTRISK6 Scale is required before routine clinical use.

Abstract
Importance Most epidemiological studies of heart failure (HF) have been conducted in high-income countries with limited comparable data from middle- or low-income countries. Objective To examine differences in HF etiology, treatment, and outcomes between groups of countries at different levels of economic development. Design, Setting, and Participants Multinational HF registry of 23 341 participants in 40 high-income, upper-middle-income, lower-middle-income, and low-income countries, followed up for a median period of 2.0 years. Main Outcomes and Measures HF cause, HF medication use, hospitalization, and death. Results Mean (SD) age of participants was 63.1 (14.9) years, and 9119 (39.1%) were female. The most common cause of HF was ischemic heart disease (38.1%) followed by hypertension (20.2%). The proportion of participants with HF with reduced ejection fraction taking the combination of a β-blocker, renin-angiotensin system inhibitor, and mineralocorticoid receptor antagonist was highest in upper-middle-income (61.9%) and high-income countries (51.1%), and it was lowest in low-income (45.7%) and lower-middle-income countries (39.5%) (P < .001). The age- and sex- standardized mortality rate per 100 person-years was lowest in high-income countries (7.8 [95% CI, 7.5-8.2]), 9.3 (95% CI, 8.8-9.9) in upper-middle-income countries, 15.7 (95% CI, 15.0-16.4) in lower-middle-income countries, and it was highest in low-income countries (19.1 [95% CI, 17.6-20.7]). Hospitalization rates were more frequent than death rates in high-income countries (ratio = 3.8) and in upper-middle-income countries (ratio = 2.4), similar in lower-middle-income countries (ratio = 1.1), and less frequent in low-income countries (ratio = 0.6). The 30-day case-fatality rate after first hospital admission was lowest in high-income countries (6.7%), followed by upper-middle-income countries (9.7%), then lower-middle-income countries (21.1%), and highest in low-income countries (31.6%). The proportional risk of death within 30 days of a first hospital admission was 3- to 5-fold higher in lower-middle-income countries and low-income countries compared with high-income countries after adjusting for patient characteristics and use of long-term HF therapies. Conclusions and Relevance This study of HF patients from 40 different countries and derived from 4 different economic levels demonstrated differences in HF etiologies, management, and outcomes. These data may be useful in planning approaches to improve HF prevention and treatment globally.

Abstract
Pulmonary hypertension (PH) is a rare condition associated with significant morbidity and mortality. The priorities for future research in PH according to patients, caregivers, and clinicians have not been established. We performed a James Lind Alliance priority setting partnership in Canada. An initial survey of 249 respondents (76% patients and/or caregivers, 12.5% clinicians) generated 1588 questions, which were combined into 187 summary questions. An evidence check identified 352 systematic reviews and guidelines which were mapped to the summary questions, which determined that 157 summary questions were unanswered by existing research. An interim prioritisation survey (240 respondents, 66% patients and/or caregivers, 18% clinicians) asked respondents to choose which of the 157 summary questions were among the 30-40 most important. In a final workshop patients, caregivers, and clinicians discussed and ranked the top 25 questions from the interim survey to identify the Top 10 PH research priorities. These results will inform researchers and funding bodies about patient, caregiver, and clinician priorities for future research on PH.

Sex-based differences in referral of heart failure patients to outpatient clinics: a scoping review. ESC Heart Fail 2022; 9:3702-3712. [PMID: 36069110 PMCID: PMC9773741 DOI: 10.1002/ehf2.14143] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 07/26/2022] [Accepted: 08/24/2022] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Guidelines recommend that hospitalized patients newly diagnosed with HF be referred to an outpatient HF clinic (HFC) within 2 weeks of discharge. Our study aims were (i) to assess the current literary landscape on the impact of patient sex on HFC referral and outcomes and (ii) to provide a qualitative overview of possible considerations for the impact of sex on referral patterns and HF characteristics including aetiology, symptom severity, investigations undertaken and pharmacologic therapy. METHODS AND RESULTS We conducted a scoping review using the Arksey and O'Malley framework and searched Medline, EMBASE, PsychINFO, Cochrane Library, Ageline databases and grey literature. Eligible articles included index HF hospitalizations or presentations to the Emergency Department (ED), a description of the HFC referral of patients not previously followed by an HF specialist and sex-specific analysis. Of the 11 372 potential studies, 8 met the inclusion criteria. These studies reported on a total of 11 484 participants, with sample sizes ranging between 168 and 3909 (25.6%-50.7% female). The included studies were divided into two groups: (i) those outlining the referral process to an HFC and (ii) studies which include patients newly enrolled in an HFC. Of the studies in Group 1, males (51%-82.4%) were more frequently referred to an HFC compared with females (29%-78.1%). Studies in Group 2 enrolled a higher proportion of males (62%-74% vs. 26%-38%). One study identified independent predictors of HFC referral which included male sex, younger age, and the presence of systolic dysfunction, the latter two more often found in males. Two studies, one from each group reported a higher mortality amongst males compared with females, whereas another study from Group 2 reported a higher hospitalization rate amongst females following HFC assessment. CONCLUSIONS Males were more likely than females to be referred to HFCs after hospitalization and visits to the Emergency Department, however heterogeneity across studies precluded a robust assessment of sex-based differences in outcomes. This highlights the need for more comprehensive longitudinal data on HF patients discharged from the acute care setting to better understand the role of sex on patient outcomes.

Abstract
Abstract
Background
Poor health-related quality of life (HRQL) is common in heart failure (HF) and strongly predicts death and HF hospitalization in all regions of the world. Understanding facors associated with HRQL could therefore lead to improved prognosis in HF patients. Despite that the majority of HF occurs in low- and middle-income countries, there are limited data characterizing self-perceived health HRQL and its correlates in these settings.
Purpose
To examine clinical and social correlates of HRQL in patients with HF from high- (HIC), upper middle- (UMIC), lower middle-(LMIC) and low-income (LIC) countries.
Methods
Between 2017 and 2020, we enrolled 23,292 patients with HF (32% inpatients, 61% men) from 40 countries in the Global Congestive Heart Failure Study. We recorded HRQL at baseline using Kansas City Cardiomyopathy Questionnaire (KCCQ)-12. In a cross-sectional analysis, we compared age- and sex-adjusted mean KCCQ-12 summary scores (SS: 0–100, higher=better) between patients from different country income levels. We used multivariable linear regression examining correlations (estimates expressed as β-coefficients) of KCCQ-12-SS with sociodemographic-, comorbidity-, treatment- and symptom-covariates. The adjusted model (37 covariates) was informed by univariable findings, clinical importance and backward selection. We used partial R2-estimates to understand the contribution to the variability in KCCQ-12-SS of 4 different groups of covariates. (sociodemographic, comorbidities, treatments and signs and symptoms of congestion).
Results
Mean age was 63 years and 40% were in NYHA class III–IV. Average HRQL was 55± SD 0.5. It was 62.5 (95% CI 62.0–63.1) in HIC, 56.8 (56.1–57.4) in UMIC, 48.6 (48.0–49.3) in LMIC, and 38.5 (37.3–39.7) in LICs (p<0.0001). Strong correlates (β-coefficient [95% CI]) of KCCQ-12-SS were NYHA class III vs class I/II (−12.1 [−12.8 to −11.4] and class IV vs. class I/II (−16.5 [−17.7 to −15.3]), effort dyspnea (−9.5 [−10.2 to −8.8]) and living in LIC vs. HIC (−5.8 [−7.1 to −4.4]). Symptoms explained most of the KCCQ-12-SS variability (partial R2=0.32 of total adjusted R2=0.51), followed by sociodemographic factors (R2=0.12). Results were consistent in populations across income levels.
Conclusion
The most important correlates of HRQL in HF patients relate to HF symptom severity, irrespective of country-income level. Improved symptom control may have a big impact on HRQL, especially in LICs.

Abstract
BACKGROUND There is no consensus on the most effective treatments of pulmonary arterial hypertension (PAH). Our objective was to compare effects of medications for PAH. METHODS We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and Clinicaltrials.gov from inception to December 2021. We performed a frequentist random-effects network meta-analysis on all included trials. We rated the certainty of the evidence using the Grades of Recommendation, Assessment, Development, and Evaluation approach. RESULTS We included 53 randomised controlled trials with 10 670 patients. Combination therapy with endothelin receptor antagonist (ERA) plus phosphodiesterase-5 inhibitors (PDE5i) reduced clinical worsening (120.7 fewer events per 1000, 95% CI 136.8-93.4 fewer; high certainty) and was superior to either ERA or PDE5i alone, both of which reduced clinical worsening, as did riociguat monotherapy (all high certainty). PDE5i (24.9 fewer deaths per 1000, 95% CI 35.2 fewer to 2.1 more); intravenous/subcutaneous prostanoids (18.3 fewer deaths per 1000, 95% CI 28.6 fewer deaths to 0) and riociguat (29.1 fewer deaths per 1000, 95% CI 38.6 fewer to 8.7 more) probably reduce mortality as compared to placebo (all moderate certainty). Combination therapy with ERA+PDE5i (49.9 m, 95% CI 25.9-73.8 m) and riociguat (49.5 m, 95% CI 17.3-81.7 m) probably increase 6-min walk distance as compared to placebo (moderate certainty). CONCLUSION Current PAH treatments improve clinically important outcomes, although the degree and certainty of benefit vary between treatments.

Evaluation of Lung Glucose Uptake with Fluorine-18 Fluorodeoxyglucose Positron Emission Tomography/CT in Patients with Pulmonary Arterial Hypertension and Pulmonary Hypertension Due to Left Heart Disease. ANNALS OF NUCLEAR CARDIOLOGY 2022; 8:21-29. [PMID: 36540173 PMCID: PMC9749761 DOI: 10.17996/anc.22-00151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Revised: 02/01/2022] [Accepted: 04/05/2022] [Indexed: 06/17/2023]
Abstract
Aim: Previous studies have demonstrated increased glucose uptake by 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) in lung parenchyma in animal models or small pulmonary arterial hypertension (PAH) cohorts. However, it is not well known whether increased FDG uptake in the lung is a unique phenomenon in PAH or whether elevated pulmonary artery pressure (PAP) induces FDG uptake. Methods and results: Nineteen patients with PAH, 8 patients with pulmonary hypertension due to left heart disease (PH-LHD), and 14 age matched control subjects were included. All PH patients underwent right heart catheterization and FDG-PET. The mean standard uptake value (SUV g/mL) of FDG in each lung was obtained and average values of both lungs were calculated as mean lung FDG SUV. The correlation between hemodynamics and mean lung FDG SUV was also analyzed in PH patients. Mean PAP (mPAP) was not significantly different between PAH and PH-LHD (45±11 vs 43±5 mmHg, p=0.51). PAH patients demonstrated significantly increased mean lung FDG SUV compared with PH-LHD and controls (PAH: 0.76±0.26 vs PH-LHD: 0.51±0.12 vs controls: 0.53±0.16, p=0.0025). The mean lung FDG SUV did not correlate with mPAP either in PAH or PH-LHD. Conclusion: PAH is associated with increased lung FDG uptake indicating increased glucose utilization in the lung. This may represent metabolic shift to glycolysis and/or active inflammation in the remodeled pulmonary vasculature, and is observed to a greater extent in PAH than in patients with PH secondary to LHD and control subjects without PH.

Mortality trends in pulmonary arterial hypertension in canada: a temporal analysis of survival per ESC/ERS Guideline Era. Eur Respir J 2021; 59:13993003.01552-2021. [PMID: 34675044 PMCID: PMC9160389 DOI: 10.1183/13993003.01552-2021] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 10/06/2021] [Indexed: 11/05/2022]
Abstract
INTRODUCTION The evolution in pulmonary arterial hypertension (PAH) management has been summarized in three iterations of the European Society of Cardiology/European Respiratory Society (ESC/ERS) guidelines. No study has assessed whether changes in management, as reflected in the changing guidelines, has translated to improved long-term survival in PAH. METHODS Mixed retrospective/prospective analysis of treatment naïve, incident PAH patients (n=392) diagnosed at three major centers in Canada from 2009-2021. Patients were divided into two groups based on their diagnosis date and in accordance with three ESC/ERS guideline iterations: 2009 and 2015. Overall survival was assessed based on date of diagnosis and initial treatment strategy (i.e. mono versus combination). RESULTS In Canada, there was a shift towards more aggressive upfront management with combination therapy after the publication of the 2015 guidelines (10.4% and 30.8% in 2009-2015 patients, and 36.0% and 57.4% in 2016-2021 patients, for baseline and 2-year follow-up respectively). A key factor associated with combination therapy after 2015 was higher pulmonary vascular resistance (p=0.009). The 1, 3 and 5 year survival rates in Canada were 89.2%, 75.6%. and 56.0%, respectively. Despite changes in management, there was no improvement in long-term survival before and after publication of the 2015 ESC/ERS guideline (p=0.53). CONCLUSIONS There was an increase in the use of initial and sequential combination therapy in Canada after publication of the 2015 ESC/ERS guidelines, which was not associated with improved long-term survival. These data highlight the continued difficulties of managing this aggressive pulmonary disease in an era without a cure.

Abstract
In this update of the Canadian Cardiovascular Society heart failure (HF) guidelines, we provide comprehensive recommendations and practical tips for the pharmacologic management of patients with HF with reduced ejection fraction (HFrEF). Since the 2017 comprehensive update of the Canadian Cardiovascular Society guidelines for the management of HF, substantial new evidence has emerged that has informed the care of these patients. In particular, we focus on the role of novel pharmacologic therapies for HFrEF including angiotensin receptor-neprilysin inhibitors, sinus node inhibitors, sodium glucose transport 2 inhibitors, and soluble guanylate cyclase stimulators in conjunction with other long established HFrEF therapies. Updated recommendations are also provided in the context of the clinical setting for which each of these agents might be prescribed; the potential value of each therapy is reviewed, where relevant, for chronic HF, new onset HF, and for HF hospitalization. We define a new standard of pharmacologic care for HFrEF that incorporates 4 key therapeutic drug classes as standard therapy for most patients: an angiotensin receptor-neprilysin inhibitor (as first-line therapy or after angiotensin converting enzyme inhibitor/angiotensin receptor blocker titration); a β-blocker; a mineralocorticoid receptor antagonist; and a sodium glucose transport 2 inhibitor. Additionally, many patients with HFrEF will have clinical characteristics for which we recommended other key therapies to improve HF outcomes, including sinus node inhibitors, soluble guanylate cyclase stimulators, hydralazine/nitrates in combination, and/or digoxin. Finally, an approach to management that integrates prioritized pharmacologic with nonpharmacologic and invasive therapies after a diagnosis of HFrEF is highlighted.

Interdepartmental program to improve outcomes for acute heart failure patients seen in the emergency department. CAN J EMERG MED 2021; 23:169-179. [PMID: 33709357 DOI: 10.1007/s43678-020-00047-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Accepted: 10/23/2020] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Acute heart failure patients often have an uncertain or delayed follow-up after discharge from the ED. Our goal was to introduce rapid-access specialty clinics to ensure acute heart failure patients were seen within 7 days, in an effort to reduce admissions and improve follow-up care. METHODS This prospective cohort study was conducted at two campuses of a large tertiary care hospital. We enrolled acute heart failure patients who presented to the ED with shortness of breath and were later discharged. Following a 12-month before period, we introduced rapid-access acute heart failure clinics staffed by cardiology and internal medicine. We allowed for a 3-month implementation period and then observed outcomes over the subsequent 12-month after period. The primary outcome was hospital admission within 30 days. Secondary outcomes included mortality and actual access to specialty care. RESULTS Patients in the before (N = 355) and after periods (N = 374) were similar for age and most characteristics. Segmented autoregression analysis demonstrated there was a pre-existing trend to fewer admissions. Attendance at a specialty clinic increased from 17.8 to 42.1% (P < 0.01) and the median days to the clinic decreased from 13 to 6 days (P < 0.01). 30-days mortality did not change. CONCLUSION Implementation of rapid-access clinics for acute heart failure patients discharged from the ED did not lead to an overall decrease in hospital admissions. It did, however, lead to increased access to specialist care, reduced follow-up times, without an increase in return ED visits or mortality. Widespread use of this rapid-access approach to a specialist can improve care for acute heart failure patients discharged home from the ED.

Canadian Cardiovascular Society/Canadian Heart Failure Society Joint Position Statement on the Evaluation and Management of Patients With Cardiac Amyloidosis. Can J Cardiol 2020; 36:322-334. [PMID: 32145862 DOI: 10.1016/j.cjca.2019.12.034] [Citation(s) in RCA: 56] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 12/04/2019] [Accepted: 12/04/2019] [Indexed: 01/29/2023] Open
Abstract
Cardiac amyloidosis is an under-recognized and potentially fatal cause of heart failure and other cardiovascular manifestations. It is caused by deposition of misfolded precursor proteins as fibrillary amyloid deposits in cardiac tissues. The two primary subtypes of systemic amyloidosis causing cardiac involvement are immunoglobulin light chain (AL), a plasma cell dyscrasia, and transthyretin (ATTR), itself subdivided into a hereditary subtype caused by a gene mutation of the ATTR protein, and an age-related wild type, which occurs in the absence of a gene mutation. Clinical recognition requires a high index of suspicion, inclusive of the extracardiac manifestations of both subtypes. Diagnostic workup includes screening for serum and/or urine monoclonal protein suggestive of immunoglobulin light chains, along with serum cardiac biomarker measurement and performance of cardiac imaging for findings consistent with amyloid infiltration. Modern cardiac imaging techniques, including the use of nuclear scintigraphy with bone-seeking radiotracer to noninvasively diagnose ATTR cardiac amyloidosis, have reduced reliance on the gold standard endomyocardial biopsy. Disease-modifying therapeutic approaches have evolved significantly, particularly for ATTR, and pharmacologic therapies that slow or halt disease progression are becoming available. This Canadian Cardiovascular Society/Canadian Heart Failure Society joint position statement provides evidence-based recommendations that support the early recognition and optimal diagnostic approach and management strategies for patients with cardiac amyloidosis. This includes recommendations for the symptomatic management of heart failure and other cardiovascular complications such as arrhythmia, risk stratification, follow-up surveillance, use of ATTR disease-modifying therapies, and optimal clinical care settings for patients with this complex multisystem disease.

Abstract
Significant practice-changing developments have occurred in the care of heart transplantation candidates and recipients over the past decade. This Canadian Cardiovascular Society/Canadian Cardiac Transplant Network Position Statement provides evidence-based, expert panel recommendations with values and preferences, and practical tips on: (1) patient selection criteria; (2) selected patient populations; and (3) post transplantation surveillance. The recommendations were developed through systematic review of the literature and using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The evolving areas of importance addressed include transplant recipient age, frailty assessment, pulmonary hypertension evaluation, cannabis use, combined heart and other solid organ transplantation, adult congenital heart disease, cardiac amyloidosis, high sensitization, and post-transplantation management of antibodies to human leukocyte antigen, rejection, cardiac allograft vasculopathy, and long-term noncardiac care. Attention is also given to Canadian-specific management strategies including the prioritization of highly sensitized transplant candidates (status 4S) and heart organ allocation algorithms. The focus topics in this position statement highlight the increased complexity of patients who undergo evaluation for heart transplantation as well as improved patient selection, and advances in post-transplantation management and surveillance that have led to better long-term outcomes for heart transplant recipients.

Abstract
AIMS This randomized controlled trial sought to determine the financial impact of an initial diagnostic strategy of coronary computed tomography angiography (CCTA) in patients with heart failure (HF) of unknown aetiology. Invasive coronary angiography (ICA) is used to investigate HF patients. CCTA may be a non-invasive cost-effective alternative to ICA. This randomized controlled trial sought to determine the financial impact of an initial diagnostic strategy of coronary computed tomography angiography (CCTA) in patients with heart failure (HF) of unknown aetiology. METHODS AND RESULTS This multicentre, international trial enrolled patients with HF of unknown aetiology. The primary outcome was the cost of CCTA vs. ICA strategies at 12 months. Clinical outcomes were also collected. An 'intention-to-diagnose' analysis was performed and a secondary 'as-tested' analysis was based on the modality received. Two hundred and forty-six patients were randomized (age = 57.8 ± 11.0 years, ejection fraction = 30.1 ± 10.1%). The severity of coronary artery disease was similar in both groups. In the 121 CCTA patients, 93 avoided ICA. Rates of downstream ischaemia and viability testing were similar for both arms. There were no significant differences in the composite clinical outcomes or quality of life measures. The cost of CCTA trended lower than ICA [CDN -$871 (confidence interval, CI -$4116 to $3028)]. Using an 'as-tested' analysis, CCTA was associated with a decrease in healthcare costs (CDN -$2932, 95% CI -$6248 to $746). CONCLUSION In patients with HF of unknown aetiology, costs were not statistically different between the CCTA and ICA strategies. CLINICAL TRIALS.GOV NCT01283659.

Abstract
This joint Canadian Heart Failure Society and the CCS Heart Failure guidelines report has been developed to provide a pan-Canadian snapshot of the current state of clinic-based ambulatory heart failure (HF) care in Canada with specific reference to elements and processes of care associated with quality and high performing health systems. It includes the viewpoints of persons with lived experience, patient care providers, and administrators. It is imperative to build on the themes identified in this survey, through engaging all health care professionals, to develop integrated and shared care models that will allow better patient outcomes. Several patient and organizational barriers to care were identified in this survey, which must inform the development of regional care models and pragmatic solutions to improve transitions for this patient population. Unfortunately, we were unsuccessful in incorporating the perspectives of primary care providers and internal medicine specialists who provide the majority of HF care in Canada, which in turn limits our ability to comment on strategies for capacity building outside the HF clinic setting. These considerations must be taken into account when interpreting our findings. Engaging all HF care providers, to build on the themes identified in this survey, will be an important next step in developing integrated and shared care models known to improve patient outcomes.

Abstract
We provide an update on Canada's first neonatal heart transplant recipient who, after cardiac retransplantation, underwent a mitral valve replacement and tricuspid valve repair. Twenty-seven years after his initial heart surgery and 13 years after his most recent transplant, this patient developed heart failure with severe mitral regurgitation secondary to a calcified mitral valve. The patient was highly sensitized with no evidence of allograft rejection; therefore, mitral and tricuspid surgery was performed. The patient did well perioperatively and remains well 18 months after surgery. To our knowledge, this novel case represents the first double-valve surgery in a patient who underwent cardiac retransplantation.

Abstract
OBJECTIVES Heart failure is a common ED presentation that is underserved by palliative care services and is associated with significant morbidity and mortality. We sought to evaluate use of palliative care services in patients with heart failure presenting to the ED. The primary outcome studied was palliative care involvement. Secondary outcomes of the study were: (1) 1-year mortality, (2) ED visits, (3) hospital admissions and (4) heart failure clinic involvement. METHODS We conducted a health records review of 500 patients with heart failure who presented to two Canadian academic hospital EDs from January to August 2013. RESULTS Patients were of mean age 80.7 years, women (53.2%) and had significant comorbidities. Only 41% of all deceased patients at 1 year had any palliative care involvement. Of those with palliative care, 44 (76%) patients had less than 2 weeks of palliative care involvement prior to death. Compared with those with no palliative care, the 79 (15.8%) patients with palliative care involvement had a higher 1-year mortality rate (70.9% vs 18.8%) and more hospital admissions/year (1.4 vs 0.85) for heart failure. CONCLUSIONS We found that few patients with heart failure had palliative care services. Additionally, the majority of those who have palliative care involvement do not meet current recommendations for early palliative care involvement in heart failure. This study suggests that the ED may be an appropriate setting to identify and refer high-risk patients with heart failure who could benefit from earlier palliative care involvement.

Abstract
Purpose A proportion of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) do not achieve treatment goals or experience side effects on their current therapy. In such cases, switching patients to a new drug while discontinuing the first may be a viable and appropriate treatment option. CAPTURE was designed to investigate how physicians manage the switching of patients to riociguat in real-world clinical practice. Observations from the study were used to assess whether recommendations in the riociguat prescribing information are reflected in clinical practice. Methods CAPTURE was an international, multicenter, uncontrolled, retrospective chart review that collected data from patients with PAH or inoperable or persistent/recurrent CTEPH who switched to riociguat from another pulmonary hypertension (PH)-targeted medical therapy. The primary objective of the study was to understand the procedure undertaken in real-world clinical practice for patients switching to riociguat. Results Of 127 patients screened, 125 were enrolled in CAPTURE. The majority of patients switched from a phosphodiesterase type 5 inhibitor (PDE5i) to riociguat and the most common reason for switching was lack of efficacy. Physicians were already using the recommended treatment-free period when switching patients to riociguat from sildenafil, but a slightly longer period than recommended for tadalafil. In line with the contraindication, the majority of patients did not receive riociguat and PDE5i therapy concomitantly. Physicians also followed the recommended dose-adjustment procedure for riociguat. Conclusion Switching to riociguat from another PH-targeted therapy may be feasible in real-world clinical practice in the context of the current recommendations.

Ejection fraction improvement and reverse remodeling achieved with Sacubitril/Valsartan in heart failure with reduced ejection fraction patients. AMERICAN JOURNAL OF CARDIOVASCULAR DISEASE 2017; 7:108-113.

Abstract
BACKGROUND Sacubitril/Valsartan has been shown to improve mortality and reduce hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF). The effect of Sacubitril/Valsartan on ejection fraction (EF) and reverse remodeling parameters have not been previously described. METHODS We performed a single-center, retrospective, cohort study of HFrEF patients (n=48) who were treated with Sacubitril/Valsartan for a median duration of 3 months (Interquartile range 2-6 months). Clinical and echocardiographic parameters were reviewed at three time points (pre-baseline which was median of 18 months before starting Sacubitril/Valsartan, baseline before treatment started, and post-Sacubitril/Valsartan). Paired sample t-test and one-way repeated measures ANOVA were used for normally distributed data, while Wilcoxon Signed Rank test for non-normally distributed data. RESULTS Sacubitril/Valsartan use was associated with an average 5% (±1.2) increase in EF, from a mean baseline of 25.33% to 30.14% (p<0.001) with a median duration of treatment 3 months. There was no significant change in mean LVEF over a median duration of 11 months (IQR 5.5-15.5) between pre-baseline and baseline time points prior to treatment (p=1.0). The mean increase in ejection fraction tended to be marginally greater in the medium/high dose cohort as compared to the low dose cohort, with a mean increase of 5.09% (±1.36) and 4.03% (±3.17), respectively (p=0.184). There was a 3.36 mm reduction in left ventricular end-systolic diameter (p=0.04), a 2.64 mm reduction in left ventricular end-diastolic diameter (p=0.02), and a 14.4 g/m2 reduction in left ventricular mass index (p<0.01). CONCLUSION Sacubitril/Valsartan was found to improve EF and multiple measures of reverse remodeling beyond the effects of concomitant optimal medical therapy. Though these results are encouraging, our small sample, observational study requires confirmation in larger cohorts with longer follow-up periods.

Abstract
INTRODUCTION Both types of sleep-disordered breathing (SDB), obstructive and central sleep apnoea (OSA and CSA, respectively), are common in patients with heart failure and reduced ejection fraction (HFrEF). In such patients, SDB is associated with increased cardiovascular morbidity and mortality but it remains uncertain whether treating SDB by adaptive servo-ventilation (ASV) in such patients reduces morbidity and mortality. AIM ADVENT-HF is designed to assess the effects of treating SDB with ASV on morbidity and mortality in patients with HFrEF. METHODS ADVENT-HF is a multicentre, multinational, randomized, parallel-group, open-label trial with blinded assessment of endpoints of standard medical therapy for HFrEF alone vs. with the addition of ASV in patients with HFrEF and SDB. Patients with a history of HFrEF undergo echocardiography and polysomnography. Those with a left ventricular ejection fraction ≤45% and SDB (apnoea-hypopnoea index ≥15) are eligible. SDB is stratified into OSA with ≥50% of events obstructive or CSA with >50% of events central. Those with OSA must not have excessive daytime sleepiness (Epworth score of ≤10). Patients are then randomized to receive or not receive ASV. The primary outcome is the composite of all-cause mortality, cardiovascular hospital admissions, new-onset atrial fibrillation requiring anti-coagulation but not hospitalization, and delivery of an appropriate discharge from an implantable cardioverter-defibrillator not resulting in hospitalization during a maximum follow-up time of 5 years. CONCLUSION The ADVENT-HF trial will help to determine whether treating SDB by ASV in patients with HFrEF improves morbidity and mortality.

Distinct Patterns of Hyperpnea During Cheyne-Stokes Respiration: Implication for Cardiac Function in Patients With Heart Failure. J Clin Sleep Med 2017; 13:1235-1241. [PMID: 29065956 DOI: 10.5664/jcsm.6788] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2017] [Accepted: 08/16/2017] [Indexed: 01/06/2023]
Abstract
STUDY OBJECTIVES In heart failure (HF), we observed two patterns of hyperpnea during Cheyne-Stokes respiration with central sleep apnea (CSR-CSA): a positive pattern where end-expiratory lung volume remains at or above functional residual capacity, and a negative pattern where it falls below functional residual capacity. We hypothesized the negative pattern is associated with worse HF. METHODS Patients with HF underwent polysomnography. During CSR-CSA, hyperpnea, apnea-hyperpnea cycle, and lung to finger circulation times (LFCT) were measured. Plasma N-terminal prohormone of brain natriuretic peptide (NT-proBNP) concentration and left ventricular ejection fraction (LVEF) were assessed. RESULTS Of 33 patients with CSR-CSA (31 men, mean age 68 years), 9 had a negative hyperpnea pattern. There was no difference in age, body mass index, and apnea-hypopnea index between groups. Patients with a negative pattern had longer hyperpnea time (39.5 ± 6.4 versus 25.8 ± 5.9 seconds, P < .01), longer cycle time (67.8 ± 15.9 versus 51.7 ± 9.9 seconds, P < .01), higher NT-proBNP concentrations (2740 [6769] versus 570 [864] pg/ml, P = .01), and worse New York Heart Association class (P = .02) than those with a positive pattern. LFCT and LVEF did not differ between groups. CONCLUSIONS Patients with HF and a negative CSR-CSA pattern have evidence of worse cardiac function than those with a positive pattern. Greater positive expiratory pressure during hyperpnea is likely generated during the negative pattern and might support stroke volume in patients with worse cardiac function. COMMENTARY A commentary on this article appears in this issue on page 1227. CLINICAL TRIAL REGISTRATION The trial is registered with Current Controlled Trials (www.controlled-trials.com; ISRCTN67500535) and Clinical Trials (www.clinicaltrials.gov; NCT01128816).
