Distinct Profiles and New Pharmacological Targets for Heart Failure with Preserved Ejection Fraction.

Background: Heart failure with preserved ejection fraction (HFpEF) is a multifactorial condition with a variety of pathophysiological causes and morphological manifestations. The inclusion criteria and patient classification have become overly simplistic due to the customary differentiation regarding the ejection fraction (EF) cutoff. EF is considered a measure of systolic function; nevertheless, it only represents a portion of the true contractile state and has been shown to have certain limits due to methodological and hemodynamic irregularities. Methods: As a result, broader randomized clinical trials have yet to incorporate the most recent criteria for HFpEF diagnosis, leading to a lack of data consistency and confusion in interpreting the results. The primary variations between the bigger clinical trials published in this context concerning patient selection and echocardiographic characteristics were analyzed. For all these reasons, we aim to clarify the main features and clinical impact of HFpEF in a study combining imaging, bio-humoral analysis, and clinical history to identify the specific subgroups that respond better to tailored treatment. Results: Disparate clinical characteristics and a lack of uniform diagnostic standards may cause suboptimal therapeutic feedback. To optimize treatment, we suggest shifting the paradigm from the straightforward EF measurement to a more comprehensive model that considers additional information, such as structural traits, related disorders, and biological and environmental data. Therefore, by evaluating certain echocardiographic and clinical factors, a stepwise diagnostic procedure may be useful in identifying patients at high risk, subjects with early HFpEF, and those with evident HFpEF. Conclusions: The present assessment underscores the significance of the precision medicine approach in guaranteeing optimal patient outcomes by providing the best care according to each distinct profile.

Pharmacological management of heart failure in adults with congenital heart disease.

Congenital heart disease (CHD) is the most common global congenital defect affecting over 2.4 million individuals in the United States. Ongoing medical and surgical advancements have improved the survival of children with CHD leading to a shift where, as of 2010, adults constitute two-thirds of the CHD patient population. The increasing number and aging of adult congenital heart disease (ACHD) patients present a clinical challenge due to heightened complexity, morbidity, and mortality. Studies indicate that 1 in 13 ACHD patients will develop heart failure (HF) in their lifetime. ACHD-HF patients experience more frequent emergency department visits, higher hospitalization rates, longer hospital stays, and higher mortality compared to non-ACHD patients with heart failure (non-ACHD-HF). Despite HF being the leading cause of death in ACHD patients, there is a notable gap in evidence regarding treatment. While guideline-directed medical therapy (GDMT) has been extensively studied in non-ACHD-HF, research specific to ACHD-HF individuals is limited. This article aims to comprehensively review available literature addressing the pharmacological treatment of ACHD-HF.

Beyond Quadruple Therapy and Current Therapeutic Strategies in Heart Failure with Reduced Ejection Fraction: Medical Therapies with Potential to Become Part of the Therapeutic Armamentarium.

Heart failure with reduced ejection fraction (HFrEF) is a complex clinical syndrome with significant morbidity and mortality and seems to be responsible for approximately 50% of heart failure cases and hospitalizations worldwide. First-line treatments of patients with HFrEF, according to the ESC and AHA guidelines, include ß-blockers, angiotensin receptor/neprilysin inhibitors, sodium-glucose cotransporter 2 inhibitors, and mineralocorticoid receptor antagonists. This quadruple therapy should be initiated during hospital stay and uptitrated to maximum doses within 6 weeks after discharge according to large multicenter controlled trials. Quadruple therapy improves survival by approximately 8 years for a 55-year-old heart failure patient. Additional therapeutic strategies targeting other signaling pathways such as ivabradine, digoxin, and isosorbide dinitrate and hydralazine combination for African Americans, as well as adjunctive symptomatic therapies, seem to be necessary in the management of HFrEF. Although second-line medications have not achieved improvements in mortality, they seem to decrease heart failure hospitalizations. There are novel medical therapies including vericiguat, omecamtiv mecarbil, genetic and cellular therapies, and mitochondria-targeted therapies. Moreover, mitraclip for significant mitral valve regurgitation, ablation in specific atrial fibrillation cases, omecamtiv mecarbil are options under evaluation in clinical trials. Finally, the HeartMate 3 magnetically levitated centrifugal left ventricular assist device (LVAD) has extended 5-year survival for stage D HF patients who are candidates for an LVAD.

Angiotensin-Neprilysin inhibition in heart failure with preserved ejection fraction: A meta-analysis of randomized controlled trials.

BACKGROUND: The effect of sacubitril/valsartan on patients with heart failure (HF) with preserved ejection fraction (HFpEF) is a topic of ongoing debate. METHODS: Medline was queried from inception through the last week of May 2023 for randomized studies assessing the effects of sacubitril/valsartan in patients with HFpEF. For continuous outcomes, we pooled either the geometric mean ratios (gMR) or weighted mean difference (WMD) with 95% confidence intervals (CI). For dichotomous outcomes, we pooled Risk ratios (RR) with 95% CI. RESULTS: Four trials were included (N=8,129). Compared to the control, sacubitril/valsartan was associated with a reduction in NT-proBNP levels (gMR: 0.84, 95% CI 0.80, 0.88) and improvement in KCCQ score (WMD: 0.85, 95% CI: 0.02, 1.67). We observed no differences for HF hospitalization (RR: 0.90, 95% CI: 0.79, 1.01), cardiovascular mortality (RR: 0.83, 95% CI: 0.52, 1.32), all-cause mortality (RR: 0.99, 95% CI: 0.86-1.13) and improvement (RR: 1.15, 95% CI: 0.93, 1.42) or worsening (RR: 0.92, 95% CI: 0.78, 1.09) of NYHA class between the sacubitril/valsartan and comparator group. Sacubitril/valsartan was generally safe, and patients were less likely to have a ≥50% decline in eGFR compared to control (RR: 0.60, 95% CI: 0.39, 0.92). CONCLUSION: Pooled analysis suggests that sacubitril/valsartan reduces natriuretic peptide levels and improves the quality of life in patients with HFpEF, which may translate into better clinical outcomes as observed by a numerical trend towards improvement in major HF outcomes with sacubitril/valsartan therapy.

Advances in the Management of Heart Failure with Reduced Ejection Fraction; The Role of SGLT2is, ARNI, Myotropes, Vericiguat, and Anti-inflammatory Agents: A Mini-review.

Heart failure with reduced ejection fraction (HFrEF) has been associated with poor prognosis, reduced quality of life, and increased healthcare expenditure. Despite tremendous advances in HFrEF management, reduced survival and a high rate of hospitalization remain unsolved issues. Furthermore, HFrEF morbidity and economic burden are estimated to increase in the following years; hence, new therapies are constantly emerging. In the last few years, a series of landmark clinical trials have expanded our therapeutic armamentarium with a ground-breaking change in HFrEF-related outcomes. Sodium-glucose co-transporter 2 inhibitors (mainly dapagliflozin and empagliflozin) have already revolutionized the management of HFrEF patients via a significant reduction in cardiovascular mortality and heart failure hospitalizations. Furthermore, vericiguat and omecamtiv mecarbil have emerged as promising and novel disease-modifying therapies. The former restores the impaired cyclic guanosine monophosphate pathway, and the latter stimulates cardiac myosin without marked arrhythmogenesis. Both vericiguat and omecamtiv mecarbil have been shown to reduce heart failure admissions. Sacubitril/valsartan is an established and effective therapy in HFrEF patients and should be considered as a replacement for angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARBs). Lastly, inflammasome activity is implicated in HFrEF pathophysiology, and the role of anti-inflammatory agents in HFrEF trajectories is readily scrutinized, yet available therapies are ineffective. This mini-review summarizes the major and most recent studies in this field, thus covering the current advances in HFrEF therapeutics.

Cambios en la selección e impacto potencial de los inhibidores de neprilisina y del receptor de la angiotensina en los pacientes sometidos a reparación mitral percutánea borde a borde / Temporal trend and potential impact of angiotensin receptor neprilysin inhibitors on transcatheter edge-to-edge mitral valve repair

Introducción y objetivos: En insuficiencia cardiaca persistente con insuficiencia mitral (IM) secundaria se debe considerar la reparación transcatéter borde-a-borde (TEER) de la válvula mitral. Los inhibidores de neprilisina (ARNIs) demostraron mejorar el pronóstico en insuficiencia cardiaca. Nuestro objetivo fue evaluar el impacto de los ARNIs en la selección y resultados. Métodos: La población del registro nacional de TEER (marzo/2012-enero/2021) se dividió en 2 grupos: a) TEER pre-ARNI (n=450) y b) TEER una vez que los ARNIs se recomendaron en guías europeas (n=639), teniendo en cuenta si se prescribieron (n=52) o no (n=587). Resultados: Un total de 1.089 pacientes consecutivos se sometieron a TEER para el tratamiento de la IM. Presentaron menor tamaño ventricular izquierdo (100 frente a 82mL, p=0,025) y mejor función (35 frente a 38%, p=0,011) en la era ARNI. A los 2 años, la mortalidad (10,6 frente a 17,3%, p <0,001) y los ingresos por insuficiencia cardiaca (16,6 frente a 27,8%, p <0,001) fueron menores, pero no la recurrencia de IM. En la era ARNI, la mortalidad fue comparable independientemente de la prescripción de ARNIs, pero tuvieron menor tasa de muerte+re-hospitalización a 2 años (OR=0,369, IC95%, 0,137-0,992, p=0,048), mejor NYHA y menor recurrencia de IM (1,9 frente al 14,3%, p=0,011). Conclusiones: Se observó una mejor selección y resultados en candidatos a TEER en la era ARNI y su prescripción se asoció a una reducción significativa de eventos globales, mejor NYHA y menor recurrencia de la IM.(AU)

Introduction and objectives: Transcatheter edge-to-edge repair (TEER) should be considered in patients with heart failure and secondary mitral regurgitation (MR). Angiotensin receptor-neprilysin inhibitors (ARNIs) have been demonstrated to improve prognosis in heart failure. We aimed to evaluate the impact ARNIs on patient selection and outcomes. Methods: The population of the Spanish TEER prospective registry (March 2012 to January 2021) was divided into 2 groups: a) TEER before the ARNI era (n=450) and b) TEER after the recommendation of ARNIs by European Guidelines (n=639), with further analysis according to intake (n=52) or not (n=587) of ARNIs. Results: A total of 1089 consecutive patients underwent TEER for secondary MR. In the ARNI era, there was a reduction in left ventricle dilation (82mL vs 100mL, P=.025), and better function (35% vs 38%, P=.011). At 2 years of follow-up, mortality (10.6% vs 17.3%, P <.001) and heart failure readmissions (16.6% vs 27.8%, P <.001) were lower in the ARNI era, but not recurrent MR. In the ARNI era, 1- and 2-year mortality were similar irrespective of ARNI intake but patients on ARNIs had a lower risk of readmission+mortality at 2 years (OR, 0.369; 95%CI, 0.137-0.992; P=.048), better NYHA class, and lower recurrence of MR III-IV (1.9% vs 14.3%, P=.011). Conclusions: Better patient selection for TEER has been achieved in the last few years with a parallel improvement in outcomes. The use of ARNIs was associated with a significant reduction in overall events, better NYHA class, and lower MR recurrence.(AU)

Evaluation of an arnis-based exercise program for community-dwelling older adults in the Philippines: An exploratory study protocol

BACKGROUND@#Arnis is the national martial art of the Philippines. Similar to Tai Chi, a martial art with established therapeutic effects, it can improve the balance control of older adults. However, no study has been conducted to prove this.@*OBJECTIVE@#This study aims to design and evaluate an Arnisbased exercise program to improve the static and dynamic balance control of community-dwelling Filipino older adults@*METHODOLOGY@#: A qualitative exploratory study will be conducted. An Arnis-based exercise program for older adults will be age-appropriately designed and video-recorded by the researchers. A heterogeneous group of resource persons composed of a Physical Therapist, Geriatrician, Sports Scientist, Arnis Expert, and Senior Citizen will be invited to watch the videos and evaluate the exercise program. Using the Delphi method and semi-structured interviews via the different online meeting platforms, they will provide feedback and comments about the exercise program based on their unique professional background, experience, and perspective. Thematic analysis will be employed in examining the gathered information. The modification of the exercise program and additional rounds of validation and feedback from the resource persons will be conducted as necessary until consensus is achieved@*EXPECTED RESULTS@#This will produce an alternative and culturally relevant exercise program that can be implemented by physical therapists and other health professionals caring for older adults in improving their balance control to reduce their risk of falling.
