Decompensated Heart Failure Research Articles

Outpatient treatment of decompensated heart failure: A systematic review and study level meta-analysis.

Patients with acutely decompensated heart failure (ADHF) are usually admitted to hospital for management. There is growing interest in delivering intravenous (IV) diuretic therapy at home, in the community or at hospital day-care units; the safety and effectiveness of outpatient-based management (OPM) for ADHF has not been established. We conducted a systematic literature review and meta-analysis to investigate the short-term safety and effectiveness of OPM compared with inpatient management (IPM) of ADHF. Pre-specified endpoints were 30day mortality and 30day hospitalization. The meta-analysis was conducted using RevMan 5.4 software. Twenty-nine studies of OPM were identified, including 7683 patients. Only five studies directly compared OPM (n=1303) with IPM (n=2047), including three observational studies, and two randomized controlled trials (RCTs). The other 24 studies only stated OPM outcomes. For the five studies comparing IPM versus OPM, patients were generally aged >75years and of similar age for each strategy, with a similar proportion of men (56%). In a study-level, aggregate analysis, 30day all-cause mortality was 9.3% (121/1303) for OPM, compared with 15.6% (320/2047) for IPM [OR 0.29 (95% CI 0.09, 0.93) P=0.04]. Four studies reported 30day all-cause hospitalization; 22.0% for IPM versus 16.8% for OPM [OR 0.73 (95% CI 0.61, 0.89), P=0.001]. In the two RCTs, we found no difference in 30day mortality or hospitalization. In observational studies, OPM of ADHF is associated with lower 30day hospitalization and lower 30day mortality; such differences were not observed in two small, single-centre RCTs. A substantial, multicentre RCT is required to confirm the safety and effectiveness of OPM for ADHF.

Workflow and Framework for Collecting and Implementing Point-of-Care Ultrasound Data in the Management of Heart Failure Patients.

Management and prevention of acute decompensated heart failure remain highly prevalent and challenging medical conditions. Incorporation of Point-of-Care Ultrasound (POCUS) as an adjunctive tool for assessing volume status and treatment response has shown significant promise. POCUS can be used for imaging internal anatomic structures serially and capturing these images for comparison and measurement over time. This protocol describes a scalable and standardized methodology for the serial assessment of the inferior vena cava (IVC). The methodology includes serial image collection, measurement, and presentation in the electronic medical record. A workflow for POCUS-acquired images of the IVC was created to capture the images and measure the diameter in a discrete data field for direct comparison over time and in response to clinical management. The protocol also includes the assessment of the presence or absence of pleural effusion as discrete data in the standardized workflow. By integrating POCUS into heart failure management, clinicians can improve patient outcomes through more precise and timely adjustments in treatment.

Fluid Restriction for Patients with Heart Failure: Current Evidence and Future Perspectives.

Fluid restriction has long been believed to benefit patients with heart failure by counteracting the activated renin-angiotensin aldosterone system and sympathetic nervous activity. However, its effectiveness remains controversial. In this paper, we summarized the current recommendations and reviewed the scientific evidence on fluid restriction in the setting of both acute decompensated heart failure and compensated heart failure. While a recent meta-analysis demonstrated the beneficial effects of fluid restriction on both all-cause mortality and hospitalization compared to usual care, several weaknesses were identified in the assessment of the methodological quality of the meta-analysis using AMSTAR 2. Further randomized controlled trials with larger sample sizes are needed to elucidate the benefits of fluid restriction for both clinical outcomes and patient-reported outcomes in patients with heart failure.

Assessment of venous congestion with venous excess ultrasound score in the prognosis of acute heart failure in the emergency department: a prospective study.

In acute decompensated heart failure (HF), systemic venous congestion contributes to patients' symptoms and hospital admissions. The purpose of our study is to determine if venous congestion, examined using the venous excess ultrasound (VExUS) score, predicts HF-related hospitalization and mortality in patients admitted to the emergency department (ED) with acute decompensated HF. Fifty patients admitted for acute HF in ED underwent ultrasound (US) assessment according to the VExUS score within the first 24 and 72 h. All patients were followed up with a telephone call at 30 and 60 days after hospital discharge. On admission, 56% had a VExUS score of 3. After 72 h, 32% had no more signs of congestion at the Doppler VExUS examination (inferior vena cava < 2 cm, VExUS score of 0); a similar percentage still exhibited a VExUS score of 3 despite therapy. Eighty per cent of patients were hospitalized after admission to the ED, while six (15%) died in-hospital; all exhibited a first-assessment VExUS score of 3. No patient with a VExUS score < 3 died during the study. During short-term follow-up, 18 patients were readmitted to the ED for acute decompensated HF. Ninety-four per cent of the readmitted patients had a VExUS score of 3 at the Doppler assessment at the first ED admission. Severe venous congestion, defined as a VExUS score of 3 at the initial assessment of patients with acute decompensated HF, predicts inpatient mortality, HF-related death, and early readmission.

Plasma soluble fms-like tyrosine kinase-1, placental growth factor, and vascular endothelial growth factor system gene variants as predictors of survival in heart failure.

Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF), components of the vascular endothelial growth factor (VEGF) system, play key roles in angiogenesis. Reports of elevated plasma levels of sFlt-1 and PlGF in coronary heart disease and heart failure (HF) led us to investigate their utility, and VEGF system gene single nucleotide polymorphisms (SNPs), as prognostic biomarkers in HF. ELISA assays for sFlt-1, PlGF and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were performed on baseline plasma samples from the PEOPLE cohort (n = 890), a study of outcomes among patients after an episode of acute decompensated HF. Eight SNPs potentially associated with sFlt-1 or PlGF levels were genotyped. sFlt-1 and PlGF were assayed in 201 subjects from the Canterbury Healthy Volunteers Study (CHVS) matched to PEOPLE participants. All-cause death was the major endpoint for clinical outcome considered. In PEOPLE participants, mean plasma levels for both sFlt-1 (125 ± 2.01 pg/ml) and PlGF (17.5 ± 0.21 pg/ml) were higher (both p < 0.044) than in the CHVS cohort (81.2 ± 1.31 pg/ml and 15.5 ± 0.32 pg/ml, respectively). sFlt-1 was higher in HF with reduced ejection fraction compared to HF with preserved ejection fraction (p = 0.005). The PGF gene SNP rs2268616 was univariately associated with death (p = 0.016), and was also associated with PlGF levels, as was rs2268614 genotype. Cox proportional hazards modelling (n = 695, 246 deaths) showed plasma sFlt-1, but not PlGF, predicted survival (hazard ratio 6.44, 95% confidence interval 2.57-16.1; p < 0.001) in PEOPLE, independent of age, NT-proBNP, ischaemic aetiology, diabetic status and beta-blocker therapy. Plasma sFlt-1 concentrations have potential as an independent predictor of survival and may be complementary to established prognostic biomarkers in HF.

The Use of Drugs that Should be Avoided or Used with Caution in Patients Hospitalized for Acute Decompensated Heart Failure.

Heart failure (HF) is a pervasive global health concern, with acute decompensated heart failure (ADHF) contributing significantly to morbidity and mortality. Medications used in patients with HF may exacerbate HF or prolong the QT interval, posing additional risks. The objective is to assess the prevalence and utilization patterns of medications known to cause or exacerbate HF and prolong the QT interval among patients with ADHF. Understanding these patterns is crucial for optimizing patient care and minimizing potential risks. A retrospective chart review was conducted at Huntsville Hospital, Huntsville, USA, covering 602 patients with ADHF over a 40-month period. Inclusion criteria involved age ≥ 18 years, a history of HF, and ADHF admission. The 2016 American Heart Association Scientific Statement was used to identify drugs that may cause or exacerbate HF and those that could prolong the QT interval RESULTS: Among the 602 patients, 57.3% received medications causing or exacerbating HF, notably albuterol (34.9%) and diabetes medications (20.4%), primarily metformin, followed by urologic agents (14.3%), mostly tamsulosin, and nonsteroidal anti-inflammatory drugs (NSAIDs) (6.1%). Moreover, 82.9% were on medications prolonging the QT interval, with loop diuretics, amiodarone, ondansetron, and famotidine most prevalent. Furthermore, 42.1% of the patients received more than two concomitant medications that prolong the QT interval, which can further exacerbate the risk of torsades de pointes. This study underscores the high prevalence of HF-causing or HF-exacerbating medications and QT-prolonging drugs in patients with ADHF. Healthcare professionals must be cognizant of these patterns, advocating for safer prescribing practices to optimize patient outcomes and reduce the burden of HF-related hospitalizations.

Management and outcomes of heart failure hospitalization among older adults in the United States and Japan.

Despite advances in therapies, the disease burden of heart failure (HF) has been rising globally. International comparisons of HF management and outcomes may reveal care patterns that improve outcomes. Accordingly, we examined clinical management and patient outcomes in older adults hospitalized for acute HF in the United States (US) and Japan. We identified patients aged >65 who were hospitalized for HF in 2013 using US Medicare data and the Japanese Registry of Acute Decompensated Heart Failure (JROADHF). We described patient characteristics, management, and healthcare utilization and compared outcomes using multivariable Cox regression during and after HF hospitalization. Among 11193 Japanese and 120289 US patients, age and sex distributions were similar, but US patients had higher comorbidity rates. The length of stay was longer in Japan (median 18 vs. 5days). While Medicare patients had higher use of implantable cardioverter defibrillator or cardiac resynchronization therapy during hospitalization (1.32% vs. 0.6%), Japanese patients were more likely to receive cardiovascular medications at discharge and to undergo cardiac rehabilitation within 3months of HF admission (31% vs. 1.6%). Physician follow-up within 30days was higher in Japan (77% vs. 57%). Cardiovascular readmission, cardiovascular mortality and all-cause mortality were 2.1-3.7 times higher in the US patients. The per-day cost of hospitalization was lower in Japan ($516 vs. $1323). We observed notable differences in the management, outcomes and costs of HF hospitalization between the USand Japan. Large differences in length of hospitalization, cardiac rehabilitation rate and outcomes warrant further research to determine the optimal length of stay and assess the benefits of inpatient cardiac rehabilitation to reduce rehospitalization and mortality.

Increased Risk of Severe Cardiovascular Events Following Exacerbations of Chronic Obstructive Pulmonary Disease: Results of the EXACOS-CV Study in Japan.

Severe exacerbations of chronic obstructive pulmonary disease (COPD) are known to increase the risk of cardiovascular events. However, this association has not been investigated specifically in patients with COPD in Japan, whose characteristics may differ from those of Western patients (i.e., western Europe, the US, and Canada). This longitudinal retrospective cohort study analyzed secondary claims data and included patients aged≥40years with COPD (International Classification of Diseases-10 codes J41-J44). All exacerbations occurring during follow-up were measured. Time-dependent Cox models were used to estimate hazard ratios (HRs) for the association between time periods following an exacerbation of COPD (vs. time prior to a first exacerbation) and occurrence of a first hospitalization for a severe fatal or non-fatal cardiovascular event. The analysis included 152,712 patients with COPD with a mean age of 73.8years and 37.6% of whom were female. During a median follow-up of 37months, 63,182 (41.4%) patients experienced≥1 exacerbation and 13,314 (8.7%) patients experienced≥1 severe cardiovascular event. Following an exacerbation of COPD, the risk of a severe cardiovascular event was increased in the first 30days [adjusted HR (aHR) 1.44, 95% confidence interval (CI) 1.33-1.55] and remained elevated for 365days post-exacerbation (aHR 1.13, 95% CI 1.04-1.23). Specifically, the risks of acute coronary syndrome or arrhythmias remained significantly increased for up to 180days, and the risk of decompensated heart failure for 1year. Among Japanese patients with COPD, the risk of experiencing a severe cardiovascular event increased following a COPD exacerbation and remained elevated for 365days, emphasizing the need to prevent exacerbations.

Ventricular Angiography: A Forgotten Diagnostic Tool?

A 76-year-old male patient presented to the emergency room with acute decompensated right heart failure and presyncope episodes. Upon admission, his electrocardiogram (ECG) showed sustained monomorphic ventricular tachycardia at 180 bpm, which was electrically cardioverted, and the patient was subsequently admitted to the intensive care unit. The echocardiography showed a very dilated right ventricle (RV) with global systolic dysfunction and akinetic anterior and lateral walls. The coronary angiography was normal. The cardiac magnetic resonance showed signs of fibro-fatty replacement of the RV myocardium. Furthermore, the ECG after cardioversion showed inverted T waves and an epsilon wave in V1-V3 leads and late potentials by signal-averaged ECG. As such, a diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC) was suspected. However, he presented no familial history of ARVC, was 76 years of age at the time of diagnosis and was asymptomatic until now. Given these considerations, we performed a right ventricular angiography which showed dilatation of the RV with akinetic/dyskinetic bulging, creating the "pile d'assiettes" image suggestive of ARVC. In the case of this patient, the RV angiography contributed to establish a diagnosis of ARVC with a very late presentation, to our knowledge the latest presentation in terms of age described in the literature.

Temporal trends in acute decompensated heart failure outcomes: A single-center 11-year retrospective analysis

BackgroundAcute Decompensated Heart Failure (ADHF) is associated with frequent hospitalizations, posing a significant health and economic burden globally. Despite advancements in heart failure management, studies delineating temporal trends in ADHF outcomes are sparse.Methods: in this retrospective analysis, ADHF patients admitted to Shamir Medical Center from 2007 to 2017 were categorized into two cohorts: early (2007–2011) and recent (2012–2017). Clinical characteristics, in-hospital interventions, and outcomes were compared. Survival analysis was performed using Kaplan-Meier methods with log-rank tests. Results8332 admitted patients were analyzed, 4366 (52.4 %) in the early period, and 3966 (47.6 %) in the recent period. In the recent cohort, ischemic heart disease decreased significantly (from 45.2 % to 34.7 %), while hypertension and smoking rates increased. Additionally, a significant increase in coronary artery bypass grafting (from 0.8 % to 3.5 %) and beta-blockers prescription (from 45.5 % to 63.4 %) post-discharge was observed. However, no substantial improvement in in-hospital mortality (8.9 % in early vs. 8.0 % in recent), 30-day (3.2 % in early vs. 3.1 % in recent), 1-year (23.3 % in early vs. 23.8 % in recent), or 5-year survival rates was noted between cohorts. A subset analysis of patients admitted to cardiology departments showed a significant reduction in in-hospital mortality in the recent cohort (12.3 % in early vs. 6.3 % in recent), yet without a corresponding long-term survival benefit. ConclusionsAdvancements in heart failure management over the 11-year study period did not demonstrate an improvement in clinical outcomes for ADHF patients, highlighting the challenge of translating advancements in the medical care of ADHF patients into long-term survival benefits.

Skeletal muscle quantity and quality evaluation in heart failure: comparing thoracic versus abdominopelvic CT approaches

Given the critical role of skeletal muscle in healthy aging, low muscle mass (myopenia) and quality (myosteatosis) can be used as predictors of poor functional and cardiometabolic outcomes. Myopenia is also a part of sarcopenia and malnutrition diagnostic criteria. However, there is limited evidence for using chest computed tomography (CT) to evaluate muscle health. We aimed to compare chest CT landmarks to the widely used L3 vertebra for single-slice skeletal muscle evaluation in patients with heart failure (HF). Patients admitted for acute decompensated HF between January 2017 and December 2018 were retrospectively analyzed. Body composition measurements were made on CT of the chest and abdomen/pelvis with or without contrast one month before discharge. Skeletal muscle index (SMI) and intermuscular adipose tissue percentage (IMAT%) were calculated at several thoracic levels (above the aortic arch, T8, and T12) and correlated to the widely used L3 level. A total of 200 patients were included, 89 (44.5%) female. The strongest correlation of thoracic SMI (for muscle quantity) and IMAT% (for muscle quality) with L3 was at the T12 level (r = 0.834, p < 0.001 and r = 0.757, p < 0.001, respectively). Cutoffs to identify low muscle mass for T12 SMI (derived from the lowest sex-stratified L3 SMI tertile) were 31.1 cm²/m² in men and 26.3 cm²/m² in women. SMI and IMAT% at T12 had excellent correlations with the widely used L3 level for muscle quantity and quality evaluation in patients with HF.

Cracking the Code of Coronary Calcium: One-year Clinical Outcomes of Intravascular Lithotripsy in All-comers and Two Complex Cohorts

Background: Severe coronary calcifications are commonly encountered in real-world populations and in left main (LM) disease, heightening complication risks including stent underexpansion. Although intravascular lithotripsy (IVL) appears safe, longer-term data in high-risk populations are lacking. The aim of this study was therefore to examine 1-year IVL outcomes for severely calcified lesions in two complex cohorts: LM stenosis and underexpanded stents (UES) during stent implantation. Methods: A registry study was carried out to examine major adverse cardiovascular events (MACEs) (MI, target vessel revascularisation [TVR], cardiac mortality). The LM and UES subgroups were compared with their counterparts in the non-LM and de novo lesion subgroups, respectively. Results: The study involved 102 participants (median age, 70 years, 68% male), and the cardiovascular burden was high (diabetes, 72%; dialysis, 18%; prior MI, 43%, median left ventricular ejection fraction, 45%). Many participants presented acutely (acute coronary syndrome, 36%; decompensated heart failure, 13%) and had complex anatomies (triple-vessel disease, 77%). The cardiovascular burden was higher in the LM and UES subgroups than in the non-LM and de novo lesion subgroups, but the rates of procedural complications and 30-day MACEs were low and were not significantly different. The 1-year MACE rate was higher in the LM group than in non-LM (29% versus 10%, p=0.042), but was non-significant after adjusting for baseline variables (OR 3.08; 95% CI [0.87–10.9]); the rates of 1-year MI, TVR and mortality did not differ from non-LM. In the UES group, 1-year MACE rate (17% versus 13%, p=0.500) was similar to that for de novo lesions. Conclusion: The preliminary data suggest that the use of IVL is reasonable when encountering stent underexpansion due to severe coronary calcifications during stent implantation. The 1-year MACE rate was higher in calcific LM stenosis, probably due to greater comorbidity burden and acute presentations.

Prognostic utility of B-type natriuretic peptide and 6-min walk test in patients with acute decompensated heart failure

BackgroundWe aimed to assess the utility of B-type natriuretic peptide (BNP) and 6-min walk test (6 MWT) together as predictors of re-hospitalization and mortality in acute decompensated heart failure (ADHF) patients. MethodsThis prospective, observational, comparative study was conducted at a tertiary care center in India between October 2016 and March 2018. Patients (aged≥18 years) with ADHF and left ventricular systolic dysfunction were included in this study. The study group (N = 100 patients) consisted of patients undergoing a second BNP test along with the 6 MWT at the time of discharge and at 3-months of discharge. The control group (N = 100 patients) consisted of patients who did not undergo these tests at discharge and/or at 3-months of discharge. Study endpoints were re-hospitalization within 6-months, and in-patient and 6-month mortality. ResultsTotal 200 patients diagnosed with ADHF were enrolled. Mean age was 53.46 ± 10.12 years in the study group and 52.98 ± 9.88 years in the control group. ROC analysis of BNP level to predict re-hospitalization revealed AUC of 0.935 (p < 0.001) at admission, 0.915 (p < 0.001) at discharge, and 0.783 (p < 0.001) at 3-months. Similarly, at discharge, ROC analysis of 6 MWT to predict death gave AUC of 0.670 (p = 0.011), and at 3-months, it was 0.838 (p < 0.001). ROC analysis of BNP level to predict mortality showed AUC of 0.960 (p < 0.001) at admission, 0.947 (p < 0.001) after discharge, and 0.960 (p = 0.002) at 3-months. ConclusionBNP levels and 6 MWT have good prognostic utility in ADHF patients, and thus may be beneficial in making therapeutic adjustments and taking precautionary measures in these patients.

Sequential Blockade with Loop Diuretics and Acetazolamide: A Novel Strategy in Acute Heart Failure

Abstract Acute decompensated heart failure (HF) is the most common form of acute HF (AHF) and presents with systemic congestion due to left ventricular dysfunction with sodium and water retention. Diuretics are the mainstay of treatment for AHF, with loop diuretics being the first-line therapy. However, in some studies, patients who were given high doses of loop diuretics were discharged from the hospital with residual signs of volume overload. Combining acetazolamide, a carbonic anhydrase inhibitor, with loop diuretics has been shown to be beneficial as it increases the efficacy of loop diuretics and reduces the signs and symptoms of congestion. Further, it can be used for the prevention or treatment of diuretic resistance (DR). Sequential nephron blockade with acetazolamide has emerged as a novel strategy for the treatment of AHF to enhance the efficacy of loop diuretics and prevent DR. This review highlights the combination of acetazolamide with loop diuretics as an alternative and possibly more effective decongestive strategy option in AHF patients. Nevertheless, there is limited evidence to support this combination therapy, and further research is necessary to substantiate its use in AHF patients.

Integrating Residents – Organizational Quality Metric of reducing 30-day readmission of patients with acute decompensated heart failure (Interdisciplinary QI project)

Introduction: Hospital readmissions post-discharge for congestive heart failure (CHF) pose a significant burden on patients and healthcare systems, indicating potential gaps in care quality. The 2022 heart failure guidelines advocate for structured workflows to address this issue. Despite this, McLaren Flint Hospital witnessed a rise in 30-day readmissions for CHF exacerbation, highlighting the need for intervention. To tackle this challenge, our resident-faculty Quality Improvement (QI) team has partnered with institutional QI/Patient Safety (PS) initiatives. Our goal is to establish a coordinated approach involving various healthcare professionals to optimize the discharge process and transition of care for CHF patients at McLaren Flint Hospital. Methods and Materials: Our intervention comprises two crucial tools: a CHF workflow sheet and a CHF medication sheet. The workflow begins with patient identification through daily census reports. Upon discharge, nurses implement the CHF medication sheet, with medications prescribed by medical floor doctors. Pharmacists and dietitians review and educate patients about medications and dietary considerations, respectively. Additionally, case managers organize post-discharge phone calls and appointments with primary care physicians within 48 to 72 hours and 7 days, respectively. Weekly reports on patients requiring cardiac rehabilitation are also dispatched. Plan-Do-Study-Act (PDSA) Toolkit guides our implementation, allowing for continuous improvement and adaptation. Results: The initial implementation phase commenced on March 6th, 2024. Nursing staff are well-versed in the workflow, and CHF medication forms are readily accessible in patient charts. However, challenges in timely medication reconciliation and orders pose operational hurdles, necessitating resolution. Ongoing evaluation will provide more comprehensive results approximately two months post-completion of the first PDSA cycle. Conclusion: Our initiative aims to address areas for improvement in reducing 30-day readmission rates post-CHF exacerbation at McLaren Flint Hospital. Utilizing the PDSA cycle toolkit, we will monitor outcomes and refine our process accordingly.

Feasibility of Short-Term Use of Ivabradine in Critical Ill Patients Who Have Atrial Fibrillation and Tachycardia.

Ivabradine is approved for heart rate reduction in patients with stable symptomatic heart failure (HF). The United States Food and Drug Administration and Taiwan Central Health Insurance Agency approved the use of ivabradine for patients with chronic stable HF with sinus rhythm, but it has not yet been approved for patients with acute decompensated HF or with atrial fibrillation (AF). To investigate whether short-term ivabradine use is feasible in critically ill patients with AF and rapid ventricular response (RVR). This study retrospectively analyzed 23 patients admitted to an intensive care unit with acute HF and AF-RVR who received ivabradine. All patients initially received a slow IV of amiodarone. Other medications for HF were prescribed according to current HF guidelines. The time taken for ivabradine to reduce HR to 80 beats per minute, referred to as "Time to 80," was measured in each patient. Overall, 69.6 % (16/23) of the patients had New York Heart Association functional class IV HF. In addition, 60.9% (14/23) of the patients required endotracheal intubation and ventilatory support, with more than half receiving vasopressor treatment to manage hypotension. Five patients died during the study period. The surviving patients had a significantly shorter "Time to 80" compared to those who did not survive (p = 0.037). Adding ivabradine to standard treatment might be feasible for critically ill patients with AF and tachycardia. The finding that surviving patients had a shorter "Time to 80" duration than those who did not survive may have clinical implications. However, further investigations are needed to assess its clinical utility.

Prescription Patterns of Sodium-glucose Cotransporter-2 Inhibitors in Adults With Type 2 Diabetes and Heart Failure With Reduced Ejection Fracture Admitted to a Tertiary Care Centre in Ontario, Canada

ObjectivesOur aim in this study was to assess early adoption patterns of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in eligible patients with type 2 diabetes (T2DM) and heart failure with reduced ejection fracture (HFrEF), and to identify gaps in practice. MethodsA retrospective chart review was conducted of patients with T2DM and HFrEF admitted with decompensated heart failure to The Ottawa Hospital under cardiology or general internal medicine from June 2019 to May 2021. Patterns were assessed at 8-month intervals (1 period before release of the Diabetes Canada 2020 guidelines and 2 periods afterward). Baseline patient characteristics, comorbidities, and prescriber information were collected. ResultsOf the 98 patients who met the inclusion criteria, 36.7% had a prescription for an SGLT2i, either on admission, discharge, or follow-up. Trends showed a gradual increase over time. On admission, 9.8% of patients were on an SGLT2i in period 1, 19.2% in period 2, and 23.3% in period 3. Patients receiving a prescription for SGLT2i on discharge were 0.0% in period 1, 10.0% in period 2, and 9.5% in period 3, all of whom were admitted under cardiology. On follow-up, 13.9% of eligible patients were started on an SGLT2i in period 1, 21.1% in period 2, and 35.0% in period 3. Endocrinology was the main prescriber of SGLT2i in the outpatient setting, followed by cardiology. ConclusionsOverall, trends show a slow but steady increase in early prescriptions of SGLT2i. However, most eligible patients were not started on therapy during our study period with variability in practice between specialties, highlighting opportunities to boost uptake in the future.

The RICA-2 registry: design and baseline characteristics of the first 1,000 patients

Background and objectiveHeart failure (HF) is a syndrome of epidemic proportions and one of the main reasons for hospital admission. Patient registries provide real-world clinical practice information which is complementary to clinical trials. RICA-2 is a registry of the Spanish Society of Internal Medicine. Its main goal is to know the clinical and epidemiological characteristics and prognostic factors of patients with HF treated in Internal Medicine Departments. The objective of this study is to present the design of the RICA-2, the baseline characteristics of the first 1000 patients included and their comparison with those of the historical cohort of the RICA registry. MethodsObservational, multicentre and prospective study of patients with HF with the following inclusion criteria: age equal to or greater than 18 years old, diagnosis of HF according to the European Guidelines, indistinct inclusion in decompensation or stable phase, of patients with de novo HF or chronic HF, regardless of left ventricular ejection fraction, aetiology and comorbidities. ResultsRICA-2 patients have advanced age (83 years old) and 51% are women. The comorbidity burden is higher than in the RICA registry (5 points in the Charlson comorbidity index), with predominating chronic decompensated HF (74%), hypertensive aetiology (39%) and preserved ejection fraction (52%). Most patients are pre-frail or vulnerable and are at risk of malnutrition. ConclusionThe RICA-2 represents a contemporary cohort of patients that will provide us with clinical, epidemiological and prognostic information on patients with acute and chronic HF treated in Internal Medicine.
