Blunted cardiovascular responses to exercise by inhibiting afferent feedback via spinal cord stimulation in heart failure
AbstractThis case study investigated the impact of SCS on alterations in blood pressure during constant-load exercise in a female patient with heart failure. Three different SCS frequencies [No SCS (~0  Hz),Low SCS (~100  Hz), andHigh SCS (~1000  Hz)] with and without ischaemic stimulation of the legs (cuffs) were randomly applied during constant-load exercise. To determine cardiovascular and ventilatory responses to exercise following SCS frequencies, BP, heart rate (HR), and respiratory gas exchange were measured. This experiment was dup licated in visit 1 and visit 2 with a random application of SCS frequency order a...

Predicting in ‐hospital mortality among patients admitted with a diagnosis of heart failure: a machine learning approach
AbstractExisting risk prediction models for hospitalized heart failure patients are limited. We identified patients hospitalized with a diagnosis of heart failure between 7 May 2013 and 26 April 2022 from a large academic, quaternary care medical centre (training cohort). Demographics, medical comorbidities, vitals, and labs were collected and were used to construct random forest machine learning models to predict in-hospital mortality. Models were compared with logistic regression, and to commonly used heart failure risk scores. The models were subsequently validated in patients hospitalized with a diagnosis of heart fail...

Intramyocardial calcification in apical hypertrophic cardiomyopathy assessed using multimodality imaging: a case series
We report five cases of ApHCM, with evidence of intramyocardial calcification on echocardiogram. On cardiac magnetic imaging (MRI), a hypointense component at early gadolinium enhancement (EGE) sequences, compatible with calcium, and a deep layer, with hyperintensity at late gadolinium enhancement (LGE) sequences, referable to fibrosis, suggest an endomyocardial fibrosis (EMF) diagnosis. EMF pathologic hallmark is endocardium and myocardium scarring, evolving to dystrophic calcification. It is found only in few ApHCM patients. Our series is the largest one described until now. Analysing patients' history, coexistent inflam...

Prediction of cardiac worsening through to cardiogenic shock in patients with acute heart failure
ConclusionsHalf of patients admitted with AHF experience WHF or new-onset CS. Chronic kidney disease, tricuspid valve regurgitation, and elevated pro-adrenomedullin concentrations predict these events. They could potentially serve as early warning signs for further deterioration in AHF patients. (Source: ESC Heart Failure)

Oral nutritional supplements in older outpatients with heart failure: rationale and design of the ALIMENT ‐HF trial
ConclusionsThe ALIMENT-HF trial will evaluate the tolerance, efficacy, and safety of high-calorie and high-protein-rich ONS in older outpatients with HF co-morbid with malnutrition and anorexia and will provide insightful information for future randomized controlled trials.

Left ventricular reverse remodelling as a promising strategy for resolving left ventricular thrombus

Age ‐stratified profiles and outcomes of patients with heart failure with preserved ejection fraction
ConclusionsYounger HFpEF patients ( ≤64 years) exhibit a male predominance, elevated BMI, and poorly controlled diabetes, highlighting the importance of glycaemic control in reducing SCD risk. Older HFpEF patients (≥65 years) are more likely to be female, with multiple comorbidities linked to an increased risk of HF-related mort ality. These findings underscore the need for physicians to recognize age-related, distinct HFpEF phenotypes for personalized patient management. (Source: ESC Heart Failure)

Missed opportunities in heart failure diagnosis and management: study of an urban UK population
ConclusionsLow survival rates were observed across all HF groups, along with suboptimal rates of NP testing and specialist assessments. These findings suggest missed opportunities for timely and accurate HF diagnosis, a pivotal first step in improving outcomes for HF patients. Addressing these gaps in diagnosis and management is urgently needed. (Source: ESC Heart Failure)

Ca2+/calmodulin ‐dependent kinase IIδC‐induced chronic heart failure does not depend on sarcoplasmic reticulum Ca2+ leak
ConclusionsS2814 phosphoresistance of RyR2 prevents the CaMKII-dependent SR Ca2+ leak induction but does not prevent the cardiomyopathic phenotype caused by enhanced CaMKII δC activity. Our data indicate that additional mechanisms—independent of SR Ca2+ leak —are critical for the maladaptive effects of chronically increased CaMKIIδC activity with respect to heart failure.

Genetic predisposition in chemotherapy ‐induced cardiomyopathy in a 65‐year‐old female with metastatic breast cancer
We present a case of a 65-year-old woman with breast cancer who developed recurrent CTRCD following low-dose chemotherapy, despite lacking conventional cardiovascular risk factors. Her medical history included anthracycline-associated cardiomyopathy, and her condition deteriorated significantly after treatment with HER2-targeted therapies. Through the use of multimodal imaging, we detected severe left ventricular systolic dysfunction. Further investigation with genetic testing revealed a likely pathogenic variant in theTNNT2 gene, suggesting a genetic predisposition to CTRCD. This case implies the potential role of genetic...

Long ‐term prognostic value of the H2FPEF score in patients undergoing transcatheter aortic valve implantation
ConclusionsThe H2FPEF score is useful for predicting long-term adverse outcomes after TAVI, including all-cause mortality, cardiovascular mortality, and HF hospitalization for patients with preserved EF. More aggressive interventions targeting HFpEF in addition to the TAVI procedure might be relevant in patients with high H2FPEF scores, particularly in those with a lower surgical risk.
