Heart failure (HF) affects 6 million people in the US, and type 2 diabetes (T2D) is a significant risk factor for HF. Since 2008, regulatory agencies have required cardiovascular safety trials for new T2D therapies, and these have consistently demonstrated the cardiovascular benefits of glucose-lowering drugs. Sodium-glucose cotransporter inhibitors (SGLTi) and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs)/glucose-dependent insulinotropic polypeptide (GIP) reduce major adverse cardiovascular events and deaths, regardless of diabetes status, and improve cardiorespiratory fitness.

Introduction: A four-drug regimen of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) is underused, in part due to prescriber inertia and low patient adherence. Although fixed-dose combination pills ('polypills') have improved adherence and clinical outcomes for other conditions, there are no polypills available that combine multiple classes of GDMT for HFrEF. Pharmacy-level over-encapsulation, in which several tablets are combined into one capsule, offers an opportunity to create customised HFrEF polypills with the goal of improving delivery of HFrEF therapies.

Implantable cardioverter-defibrillators (ICDs) are recommended to reduce the risk of sudden cardiac death (SCD) in patients with heart failure with reduced ejection fraction (HFrEF). The landmark studies leading to the current guideline recommendations preceded the 4 pillars of guideline-directed medical therapies (GDMTs). Therefore, some have questioned the role of ICDs for primary prevention in current clinical practice.

Introduction: Heart failure (HF) is a frequent cause of readmissions. Despite caring for underresourced patients and dependence on government funding, safety net hospitals frequently incur penalties for failing to meet pay-for-performance readmission metrics. Limited research exists on the causes of HF readmissions in safety net hospitals.

Background: Ischemic cardiomyopathy is the leading cause of heart failure (HF). Most patients do not undergo coronary assessment after HF diagnosis. There are no randomized clinical trials of coronary assessment after HF diagnosis.

Article Synopsis
  • This text outlines a new clinic model called Heart Plus that combines Addiction Medicine and Cardiology to treat patients with stimulant-associated cardiomyopathy (SA-CMP).
  • The approach uses contingency management to significantly improve outpatient care engagement and reduce emergency visits and hospital admissions among these patients.
  • Participants experienced a decrease in stimulant use and were better positioned to access social support services, leading to improved overall health and well-being.

Introduction: Although lower socioeconomic status (SES) has been associated with worse in-hospital outcomes among patients with heart failure, the in-hospital outcomes for patients undergoing durable Left Ventricular Assist Device (LVAD) implantation or Heart Transplantation (HT) based on SES have not been well characterized.

Methods: We analyzed data from the National Inpatient Sample of hospitalizations between January 2016 and December 2020 of patients aged 18 and over who underwent a HT or newly implanted LVAD. Quartile classification of the median household income of the patient's residential zip code was used to estimate SES.

Article Synopsis
  • Ischemic cardiomyopathy leads to heart failure (HF), but many patients don't get coronary assessments, and the relationship between assessment and HF outcomes in safety-net populations is unclear.
  • A study of electronic health records from San Francisco Health Network revealed that only 26.9% of HF patients underwent coronary assessment, with notable disparities based on age, gender, race/ethnicity, and medical history.
  • The analysis suggested that coronary assessment is linked to lower mortality rates and improved health outcomes for HF patients, indicating the necessity for more comprehensive evaluation post-diagnosis.

Heart failure (HF) disproportionately impacts African Americans. We evaluated existing quality improvement (QI) initiatives and patient and provider perceptions of barriers to HF care to develop equity-centered QI recommendations. We performed a literature review, interviewed providers and patients (=11), and conducted a root cause analysis at a safety net hospital in San Francisco, California.

Background: Thirty-day readmission following heart failure hospitalization impacts hospital performance measures and reimbursement. We investigated readmission characteristics and the magnitude of 30-day hospital readmissions after hospital discharge for heart failure using the Healthcare Cost and Utilization Project State Inpatient Databases (SID).

Methods: Adults aged ≥ 40 years hospitalized with a primary discharge diagnosis of heart failure from 2007-2011 were identified in the California, New York, and Florida SIDs.

Background: ATL-146e is an adenosine A(2A) agonist that has recently been demonstrated to improve neurological outcome in spinal cord injury in animals. In the current study, we extended the treatment paradigm and tested neurobehavioral functioning out to 1 week after injury to assess if early neurological improvement is sustained long term by an adenosine analogue.

Materials And Methods: New Zealand White rabbits (3.

Correlated neuronal activity is believed to play an important role in refining and maintaining cortical circuitry during early development. Here we provide evidence that globally and locally correlated activity mediate different forms of adult plasticity. Pulses of broad-spectrum noise were used to activate time-locked responses across large areas of the rat auditory cortex, globally synchronizing cortical activity.
