Effect of Carillon Mitral Contour System on patient‐reported outcomes in functional mitral regurgitation: an individual participant data meta‐analysis
No full textAbstract Aims The Carillon Mitral Contour System has been shown to reduce mitral regurgitation and left ventricular volumes in symptomatic heart failure patients with functional mitral regurgitation. We sought to evaluate the effects of the Carillon device on quality of life and functional capacity in these patients. Methods and results An individual participant data meta‐analysis was conducted utilizing data from REDUCE‐FMR, TITAN, and TITAN II studies. The main outcomes assessed were changes from baseline in Kansas City Cardiomyopathy Questionnaire overall summary scores (KCCQ‐OSS), 6 min walk test (6MWT) distance, and New York Heart Association (NYHA) classification at Months 1 and 12 after device implantation. Subgroup analyses were conducted for patients with severe functional mitral regurgitation (Grade 3 or 4). Pooled estimates were calculated using a random‐effects model and are presented as weighted proportions or weighted mean differences along with 95% confidence intervals (CIs). Among 139 patients included in the analysis, Carillon device significantly improved the 6MWT distance (63.0 m; 95% CI 18.8–107.2, P = 0.0056) and KCCQ‐OSS score (15.1; 95% CI 5.6–24.7, P = 0.0022) at 1 month from baseline. These benefits were sustained at 12 months (64.1 m; 95% CI 13.2–115.0, P = 0.0141, for 6MWT distance, and 12.3; 95% CI 4.7–19.8, P = 0.0019, for KCCQ‐OSS score). More than 50% of the patients had improvements in KCCQ‐OSS by ≥5 (60.4%; 95% CI 47.4–72.1) and 10 points (50.5%; 95% CI 34.9–66.0) at 12 months. Almost half of the patients experienced a ≥1 class improvement in NYHA class after implantation of the device at 1 month (67.9%; 95% CI 37.3–88.3) and at 12 months (48.8%; 95% CI 31.8–66.2). Results remained similar for KCCQ‐OSS, 6MWT distance, and NYHA classification when only patients with Grade 3 or 4 mitral regurgitation were analysed. The pooled estimates of 30 day and 1 year all‐cause mortality were 2.2% (95% CI 0.7–6.5) and 17.3% (95% CI 11.8–24.5), respectively. Conclusions The Carillon Mitral Contour System significantly improved patient‐reported quality‐of‐life outcomes in heart failure patients with functional mitral regurgitation
Global epidemiology of heart failure
No full text: Heart failure (HF) is a heterogeneous clinical syndrome marked by substantial morbidity and mortality. The natural history of HF is well established; however, epidemiological data are continually evolving owing to demographic shifts, advances in treatment and variations in access to health care. Although the incidence of HF has stabilized or declined in high-income countries over the past decade, its prevalence continues to increase, driven by an ageing population, an increase in risk factors, the effectiveness of novel therapies and improved survival. This rise in prevalence is increasingly noted among younger adults and is accompanied by a shift towards HF with preserved ejection fraction. However, disparities exist in our epidemiological understanding of HF burden and progression in low-income and middle-income countries owing to the lack of comprehensive data in these regions. Therefore, the current epidemiological landscape of HF highlights the need for periodic surveillance and resource allocation tailored to geographically vulnerable areas. In this Review, we highlight global trends in the burden of HF, focusing on the variations across the spectrum of left ventricular ejection fraction. We also discuss evolving population-based estimates of HF incidence and prevalence, the risk factors for and aetiologies of this disease, and outcomes in different geographical regions and populations
Ferric carboxymaltose for the treatment of iron‐deficient heart failure patients: a systematic review and meta‐analysis
No full textAbstract Aims Intravenous ferric carboxymaltose (FCM) has been shown to improve functional capacity and quality of life in iron deficient heart failure patients. However, FCM's effect on hospitalizations and mortality remains unclear as previous randomized controlled trials (RCTs) and their meta‐analyses have been underpowered to detect significant differences. We sought to conduct an updated meta‐analysis using recently published RCT data. Methods and results Online databases were searched from inception until November 2020 for RCTs evaluating the effects of FCM on clinical outcomes in iron‐deficient heart failure patients. Outcomes of interest included heart failure hospitalizations, all‐cause mortality, and cardiovascular mortality. Meta‐analysis was performed using a fixed‐effect model and estimates were reported as odds ratios (ORs), hazard ratios, or rate ratios (RRs) along with corresponding 95% confidence intervals (CIs). A total of 1947 patients ( n = 1062 in the FCM group; n = 885 in the placebo group) were included. FCM, compared with placebo, significantly reduced the risk of the composite endpoint of time to first heart failure hospitalization or cardiovascular death (hazard ratio = 0.76; 95% CI = 0.63–0.90; I 2 = 55%). FCM also significantly reduced the risk of recurrent heart failure hospitalizations (RR = 0.68; 95% CI = 0.54–0.85; I 2 = 71%) and recurrent cardiovascular hospitalizations (RR = 0.71; 95% CI = 0.59–0.86; I 2 = 56%). However, FCM had no significant effect on the risk of all‐cause (OR = 0.97; 95% CI = 0.73–1.28; I 2 = 0%) or cardiovascular mortality (OR = 0.93; 95% CI = 0.69–1.27; I 2 = 0%). Conclusions Ferric carboxymaltose reduces heart failure hospitalizations and cardiovascular hospitalizations with no beneficial effect on all‐cause and cardiovascular mortality in iron‐deficient heart failure patients. These findings reinforce the role of FCM as a therapeutic option in heart failure patients
Percutaneous repair of moderate‐to‐severe or severe functional mitral regurgitation in patients with symptomatic heart failure: Baseline characteristics of patients in the RESHAPE‐HF2 trial and comparison to COAPT and MITRA‐FR trials
No full textABSTRACT Aim The RESHAPE‐HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE‐HF2 trial compared to those enrolled in the COAPT and MITRA‐FR trials. Methods and results The RESHAPE‐HF2 study is an investigator‐initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate‐to‐severe or severe FMR, for whom isolated mitral valve surgery was not recommended. Patients were randomized 1:1 to a strategy of delivering or withholding MitraClip. Of 506 patients randomized, the mean age of the patients was 70 ± 10 years, and 99 of them (20%) were women. The median EuroSCORE II was 5.3 (2.8–9.0) and median plasma N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) was 2745 (1407–5385) pg/ml. Most patients were prescribed beta‐blockers (96%), diuretics (96%), angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor–neprilysin inhibitors (82%) and mineralocorticoid receptor antagonists (82%). The use of sodium–glucose cotransporter 2 inhibitors was rare (7%). Cardiac resynchronization therapy (CRT) devices had been previously implanted in 29% of patients. Mean LVEF, left ventricular end‐diastolic volume and effective regurgitant orifice area (EROA) were 31 ± 8%, 211 ± 76 ml and 0.25 ± 0.08 cm 2 , respectively, whereas 44% of patients had mitral regurgitation severity of grade 4+. Compared to patients enrolled in COAPT and MITRA‐FR, those enrolled in RESHAPE‐HF2 were less likely to have mitral regurgitation grade 4+ and, on average, HAD lower EROA, and plasma NT‐proBNP and higher estimated glomerular filtration rate, but otherwise had similar age, comorbidities, CRT therapy and LVEF. Conclusion Patients enrolled in RESHAPE‐HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate‐to‐severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA‐FR trials. The results of RESHAPE‐HF2 will provide crucial insights regarding broader application of the transcatheter edge‐to‐edge repair procedure in clinical practice.Abbott Fund https://doi.org/10.13039/10000004

No full textABSTRACT The Society on Cachexia and Wasting Disorders (SCWD) convened a Regulatory and Trial Update Workshop in Washington, D.C., in December 2024, assembling experts from academic institutions, the pharmaceutical industry and the US Food and Drug Administration (FDA) for focused discussions. This article summarizes the latter half of the meeting, which primarily focused on novel anti‐obesity therapies based on incretin pathway alteration. Discussions highlighted the impact of glucagon‐like peptide‐1 (GLP‐1) receptor agonists or GLP‐1/glucose‐dependent insulinotropic polypeptide (i.e., GLP‐1/GIP) agonists on body composition and muscle health; the challenges of distinguishing ‘true’ skeletal muscle from fat‐free tissue; the impact of treatment discontinuation and weight regain; advances in imaging and quantitative assessment of lean body mass; as well as insights from emerging muscle‐preserving therapies (e.g., bimagrumab, pemvidutide and enobosarm). There are significant challenges in defining meaningful structural, functional and patient‐reported endpoints for the use of muscle‐‘protective’ drug therapies in the context of weight loss therapies. These also involve significant regulatory considerations for future drug development and approval pathways, for instance related to the very large number of individuals that may be considered for these therapeutic approaches as well as from the potential long (or life‐long) duration of therapy considered with these drugs. Together, these discussions highlight the growing importance of integrating body composition and functional assessments in future clinical trials
