Advanced Markers for Hemodynamic Monitoring in Cardiogenic Shock and End-Stage Heart Failure: A Mini Review.

Right heart catheterization (RHC) provides critical hemodynamic insights by measuring atrial, ventricular, and pulmonary artery pressures, as well as cardiac output (CO). Although the use of RHC has decreased, its application has been linked to improved outcomes. Advanced hemodynamic markers such as cardiac power output (CPO), aortic pulsatility index (API), pulmonary artery pulsatility index (PAPi), right atrial pressure to pulmonary capillary wedge pressure ratio (RAP/PCWP) and right ventricular stroke work index (RVSWI) have been introduced to enhance risk stratification in cardiogenic shock (CS) and end-stage heart failure (HF) patients.

Novel therapeutic agents for cardiometabolic risk mitigation in heart transplant recipients.

Heart transplant (HT) recipients experience high rates of cardiometabolic disease. Novel therapies targeting hyperlipidemia, diabetes, and obesity, including proprotein convertase subtilisin/kexin inhibitors, sodium-glucose cotransporter-2 inhibitors, and glucagon-like peptide-1 agonists, are increasingly used for cardiometabolic risk mitigation in the general population. However, limited data exist to support the use of these agents in patients who have undergone heart transplantation.

Implementing Precision Medicine for Dilated Cardiomyopathy: Insights from The DCM Consortium.

Background: Clinical genetic evaluation of dilated cardiomyopathy (DCM) is implemented variably or not at all. Identifying needs and barriers to genetic evaluations will enable strategies to enhance precision medicine care.

Methods: An online survey was conducted in June 2024 among cardiologist investigators of the DCM Consortium from US advanced heart failure/transplant (HF/TX) programs to collect demographics, training, program characteristics, genetic evaluation practices for DCM, and implementation needs.

The Impact of Kinlessness on Older Adults with Advanced Heart Failure.

Markers of social health, including kinlessness, social isolation and loneliness, have important implications for quality of life and health for older adults. As the population ages, there is a growing cohort of kinless older adults without living partners or children, particularly among disadvantaged groups. Kinlessness has been associated with worse mental and physical health, significant unmet care needs, increased risk of dementia, higher rates of long-term placement, and higher mortality rates than those for patients with kin.

American registry of ambulatory and acute decompensated heart failure (AMERICCAASS registry): Rationale and design.

Aims: Heart failure (HF) is a highly prevalent and progressive condition associated with significant morbidity and mortality rates. Acute decompensated HF precipitates millions of hospitalizations each year. Despite therapeutic advances, the overall prognosis of HF is poor.

Associations Between Cardiac Function and Brain Health in Diverse Middle-Aged Adults: The Dallas Heart Study-2.

Background: Previous studies have linked cardiovascular risk factors during midlife to cognitive function in later life. However, few studies have looked at the association between cardiac function, brain structure, and cognitive function and even less have included diverse middle-aged populations.

Objectives: The objective of this study was to determine associations between cardiac and brain structure and function in a multiethnic cohort of middle-aged adults.

Sodium-Glucose Cotransporter 2 Inhibitors and Mycotic Genital or Urinary Tract Infections in Heart Failure.

Sodium-glucose cotransporter 2 inhibitors (SGLT2is) improve clinical outcomes in persons with heart failure (HF). This class of agents has been consistently associated with an increased risk of mycotic genital infections (MGIs), and in some, but not all trials, urinary tract infections (UTIs). Other medications widely used for cardiac conditions do not cause MGIs and UTIs, so cardiologists and their supporting teams will be encountering clinical questions that they previously did not have to address.

Circulating transthyretin and retinol binding protein 4 levels among middle-age V122I carriers in the general population.

Background: Hereditary transthyretin cardiac amyloidosis (ATTRv-CA) has a long latency phase before clinical onset, creating a need to identify subclinical disease. We hypothesized circulating transthyretin (TTR) and retinol binding protein 4 (RBP4) levels would be associated with carrier status and correlated with possible evidence of subclinical ATTRv-CA.

Methods: TTR and RBP4 were measured in blood samples from V122I carriers and age-, sex- and race-matched non-carrier controls (1:2 matching) among Dallas Heart Study participants (phases 1 (DHS-1) and 2 (DHS-2)).

A Phenomapping Tool and Clinical Score to Identify Low Diuretic Efficiency in Acute Decompensated Heart Failure.

Background: Individuals with acute decompensated heart failure (ADHF) have a varying response to diuretic therapy. Strategies for the early identification of low diuretic efficiency to inform decongestion therapies are lacking.

Objectives: The authors sought to develop and externally validate a machine learning-based phenomapping approach and integer-based diuresis score to identify patients with low diuretic efficiency.

American Registry of Ambulatory or acutely decompensated heart failure (AMERICCAASS Registry): First 1000 patients.

Background: About 80% of cardiovascular diseases (including heart failure [HF]) occur in low-income and developing countries. However, most clinical trials are conducted in developed countries.

Hypothesis: The American Registry of Ambulatory or Acutely Decompensated Heart Failure (AMERICCAASS) aims to describe the sociodemographic characteristics of HF, comorbidities, clinical presentation, and pharmacological management of patients with ambulatory or acutely decompensated HF in America.

Oxygen Uptake Efficiency Slope and Prognosis in Heart Failure With Reduced Ejection Fraction.

The prognostic utility of the oxygen uptake efficiency slope (OUES) in heart failure with reduced ejection fraction is uncertain. In this post hoc analysis of the HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) trial (n = 2,074), we tested for associations of OUES and peak oxygen uptake (VO) with heart failure hospitalization or cardiovascular death in multivariable Cox regression models, adjusting for minute ventilation/carbon dioxide production (VE/VCO) slope and other important confounders. Harrell's C-statistics assessed the discriminatory performance of OUES and peak VO.
