Project description:This guideline describes the approach and expertise needed for the genetic evaluation of cardiomyopathy. First published in 2009 by the Heart Failure Society of America (HFSA), the guideline has now been updated in collaboration with the American College of Medical Genetics and Genomics (ACMG). The writing group, composed of cardiologists and genetics professionals with expertise in adult and pediatric cardiomyopathy, reflects the emergence and increased clinical activity devoted to cardiovascular genetic medicine. The genetic evaluation of cardiomyopathy is a rapidly emerging key clinical priority, because high-throughput sequencing is now feasible for clinical testing and conventional interventions can improve survival, reduce morbidity, and enhance quality of life. Moreover, specific interventions may be guided by genetic analysis. A systematic approach is recommended: always a comprehensive family history; an expert phenotypic evaluation of the proband and at-risk family members to confirm a diagnosis and guide genetic test selection and interpretation; referral to expert centers as needed; genetic testing, with pre- and post-test genetic counseling; and specific guidance as indicated for drug and device therapies. The evaluation of infants and children demands special expertise. The approach to managing secondary and incidental sequence findings as recommended by the ACMG is provided.

Project description:ObjectivesThis study sought to determine clinician and scientist involvement in heart failure (HF) clinical research and to describe the challenges of conducting clinical trials in the United States.BackgroundImprovements in the current capability, potential, and deficiencies of the HF clinical research infrastructure in the United States are needed in order to enhance efficiency and impact.MethodsThe Heart Failure Society of America (HFSA) distributed an electronic survey regarding HF clinical trial activity for the purpose of understanding the barriers that exist to conducting high-quality HF clinical research.ResultsOverall, 1,794 HFSA members were queried, and 434 members (24%) completed surveys, whereas a total of 7,589 individuals with interest in HF were queried, and 615 completed surveys. Of the respondents, 410 (67%) were actively engaged in HF research and 120 (20%) were interested in research. Most respondents, 270, were physicians (44%); 311 of the total (76% of the total and 80% of physicians) practiced in academic institutions; 333 respondents (81%) had served as principal investigators and 73 (18%) as site coordinators. Respondents active in clinical research usually participated in 1 to 5 trials and enrolled 1 to 20 patients annually. Institutional review board (IRB) approval typically required 3 months, and contract completion required 3 to 6 months per site. The greatest barriers to research were insufficient site budgets, delay in contracting, inability to find participants meeting trial entry criteria, and unavailability of qualified study coordinators.ConclusionsMany U.S. clinical research sites are constrained by budgetary, staffing, and contractual issues. The HFSA Research Network seeks to unify interested sites and deconstruct barriers to permit high-value HF research.

Project description:Heart failure (HF) afflicts nearly 6 million Americans, resulting in one million emergency department (ED) visits and over one million annual hospital discharges. An aging population and improved survival from cardiovascular diseases is expected to further increase HF prevalence. Emergency providers play a significant role in the management of patients with acute heart failure (AHF). It is crucial that emergency physicians and other providers involved in early management understand the latest developments in diagnostic testing, therapeutics and alternatives to hospitalization. Further, clinical trials must be conducted in the ED in order to improve the evidence base and drive optimal initial therapy for AHF. Should ongoing and future studies suggest early phenotype-driven therapy improves in-hospital and post-discharge outcomes, ED treatment decisions will need to evolve accordingly. The potential impact of future studies which incorporate risk-stratification into ED disposition decisions cannot be underestimated. Predictive instruments that identify a cohort of patients safe for ED discharge, while simultaneously addressing barriers to successful outpatient management, have the potential to significantly impact quality of life and resource expenditures.

Project description:ObjectivesThe goal of this study was to evaluate the prevalence, characteristics, and outcomes of patients with advanced heart failure (HF) in a geographically defined population.BackgroundSome patients with HF progress to advanced HF, characterized by debilitating HF symptoms refractory to therapy. Limited data are available on the epidemiology and outcomes of patients with advanced HF.MethodsThis was a population-based cohort study of all Olmsted County, Minnesota, adults with and without HF from 2007 to 2017. The 2018 European Society of Cardiology advanced HF diagnostic criteria were operationalized and applied to all patients with HF. Hospitalization and mortality in advanced HF, overall and according to ejection fraction (EF) type (reduced EF <40% [HFrEF], mid-range EF 40%-49% [HFmrEF], and preserved EF ≥50% [HFpEF]) were examined using Andersen-Gill and Cox models.ResultsOf 6,836 adults with HF, 936 (13.7%) met criteria for advanced HF. The prevalence of advanced HF increased with age and was higher in men. At advanced HF diagnosis, 396 (42.3%) patients had HFrEF, 134 (14.3%) had HFmrEF, and 406 (43.4%) had HFpEF. The median (interquartile range) time from advanced HF diagnosis to death was 12.2 months (3.7-29.9 months). The mean rate of hospitalization was 2.91 (95% CI: 2.78-3.06) per person-year in the first year after advanced HF diagnosis. There were no differences in risks of all-cause mortality or hospitalization by EF. Patients with advanced HFpEF were at lower risk for cardiovascular mortality compared with advanced HFrEF (HR: 0.79; 95% CI: 0.65-0.97).ConclusionsIn this population-based study, more than one-half of patients with advanced HF had mid-range or preserved EF, and survival was poor regardless of EF.

Project description:BackgroundAcute decompensated heart failure (ADHF) is a highly morbid condition among adults. Little is known about outcomes in children with ADHF. We analyzed the Pediatric Cardiac Critical Care Consortium registry to determine the epidemiology, contemporary treatments, and predictors of mortality in critically ill children with ADHF.MethodsCardiac intensive care unit (CICU) patients ≤18 years of age meeting Pediatric Cardiac Critical Care Consortium criteria for ADHF were included. ADHF was defined as systolic or diastolic dysfunction requiring continuous vasoactive or diuretic infusion, respiratory support, or mechanical circulatory support. Demographics, diagnosis, therapies, complications, and mortality are described for the cohort. Predictors of CICU mortality were identified using logistic regression.ResultsAmong 26 294 consecutive admissions (23 centers), 1494 (6%) met criteria for analysis. Median age was 0.93 years (interquartile range, 0.1-9.3 years). Patients with congenital heart disease (CHD) comprised 57% of the cohort. Common therapies included the following: vasoactive infusions (88%), central venous catheters (86%), mechanical ventilation (59%), and high flow nasal cannula (46%). Common complications were arrhythmias (19%), cardiac arrest (10%), sepsis (7%), and acute renal failure requiring dialysis (3%). Median length of CICU stay was 7.9 days (interquartile range, 3-18 days) and the CICU readmission rate was 22%. Overall, CICU mortality was 15% although higher for patients with CHD versus non-CHD (19% versus 11%; P<0.001). Independent risk factors associated with CICU mortality included age <30 days, CHD, vasoactive infusions, ventricular tachycardia, mechanical ventilation, sepsis, pulmonary hypertension, extracorporeal membrane oxygenation, and cardiac arrest.ConclusionsADHF in children is characterized by comorbidities, high mortality rates, and frequent readmission, especially among patients with CHD. Opportunities exist to determine best practices around appropriate use of mechanical support, cardiac arrest prevention, and optimal heart transplantation candidacy to improve outcomes for these patients.

Project description:In response to the COVID-19 pandemic, US federal and state governments have implemented wide-ranging stay-at-home recommendations as a means to reduce spread of infection. As a consequence, many US healthcare systems and practices have curtailed ambulatory clinic visits-pillars of care for patients with heart failure (HF). In this context, synchronous audio/video interactions, also known as virtual visits (VVs), have emerged as an innovative and necessary alternative. This scientific statement outlines the benefits and challenges of VVs, enumerates changes in policy and reimbursement that have increased the feasibility of VVs during the COVID-19 era, describes platforms and models of care for VVs, and provides a vision for the future of VVs.

Project description:The heart failure syndrome has first been described as an emerging epidemic about 25 years ago. Today, because of a growing and ageing population, the total number of heart failure patients still continues to rise. However, the case mix of heart failure seems to be evolving. Incidence has stabilized and may even be decreasing in some populations, but alarming opposite trends have been observed in the relatively young, possibly related to an increase in obesity. In addition, a clear transition towards heart failure with a preserved ejection fraction has occurred. Although this transition is partially artificial, due to improved recognition of heart failure as a disorder affecting the entire left ventricular ejection fraction spectrum, links can be made with the growing burden of obesity-related diseases and with the ageing of the population. Similarly, evidence suggests that the number of patients with heart failure may be on the rise in low-income countries struggling under the double burden of communicable diseases and conditions associated with a Western-type lifestyle. These findings, together with the observation that the mortality rate of heart failure is declining less rapidly than previously, indicate we have not reached the end of the epidemic yet. In this review, the evolving epidemiology of heart failure is put into perspective, to discern major trends and project future directions.

Project description: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.

Project description:Physicians working in Europe and the United States should suspect Chagas heart failure in every patient coming from Latin America with chronic heart failure. Diagnosis should be confirmed by positive serology. Right bundle branch block and left anterior fascicular block on 12-lead electrocardiogram, enlarged cardiac silhouette with no pulmonary congestion on chest X-ray and left ventricular apical aneurysm on echocardiography are the distinctive features of this condition. The clinical course is poorer than that of non-Chagas heart failure; however, medical treatment is similar. Implantable cardioverter-defibrillators are useful in the primary and secondary prevention of sudden cardiac death. Cardiac resynchronisation therapy can be given to patients on optimal medical therapy and with lengthened QRS complex. Heart transplantation is the treatment of choice for patients with end-stage Chagas heart failure.

Project description:ObjectiveThere is increasing attention to cardiovascular diseases in low-income countries. However, little is known about heart failure (HF) in rural areas, where most of the populations in low-income countries live. We studied HF epidemiology, care delivery and outcomes in rural Haiti.MethodsAmong adults admitted with HF to a rural Haitian tertiary care hospital during a 12-month period (2013-2014), we studied the clinical characteristics and short-term outcomes including length of stay, inhospital death and outpatient follow-up rates.ResultsHF accounted for 392/1049 (37%) admissions involving 311 individuals; over half (60%) were women. Mean age was 58.8 (SD 16.2) years for men and 48.3 (SD 18.8) years for women; 76 (41%) women were <40 years of age. Median length of stay was 10 days (first and second quartiles 7, 17), and inhospital mortality was 12% (n=37). Ninety nine (36%) of the 274 who survived their primary hospitalisation followed-up at the hospital's outpatient clinic, and 18 (6.6%) were readmitted to the same hospital within 30 days postdischarge. Decreased known follow-up (p<0.01) and readmissions (p=0.03) were associated with increased distance between patient residence and hospital. Among the one-quarter (81) patients with echocardiograms, causes of HF included: non-ischaemic cardiomyopathy (64%), right HF (12%), hypertensive heart disease (7%) and rheumatic heart disease (5%). One-half of the women with cardiomyopathy by echocardiogram had peripartum cardiomyopathy.ConclusionsHF is a common cause of hospitalisation in rural Haiti. Among diagnosed patients, HF is overwhelming due to non-atherosclerotic heart disease and particularly affects young adults. Implementing effective systems to improve HF diagnosis and linkage to essential outpatient care is needed to reduce long-term morbidity and mortality.
