Using electronic medical records to identify patients at risk for underlying cardiac amyloidosis.

Background: Identification of transthyretin cardiac amyloidosis (ATTR-CA) patients is largely based on pattern recognition by providers, and this can be automated through electronic medical systems (EMR).

Methods: All patients in a large academic hospital with age > 60, ICD-10 code for chronic diastolic heart failure and no previous diagnosis of any amyloidosis were included. An Epic EMR scoring logic assigned risk scores to patients for ICD-10 and CPT codes associated with ATTR-CA, as follows: carpal tunnel syndrome (score 5), aortic stenosis/TAVR (5), neuropathy (4), bundle branch block (4), etc.

Evaluating the Abuse Potential of Lenabasum, a Selective Cannabinoid Receptor 2 Agonist.

Endocannabinoids, which are present throughout the central nervous system (CNS), can activate cannabinoid receptors 1 and 2 (CB1 and CB2). CB1 and CB2 agonists exhibit broad anti-inflammatory properties, suggesting their potential to treat inflammatory diseases. However, careful evaluation of abuse potential is necessary.

Novel cannabinoid receptor 1 inverse agonist CRB-913 enhances efficacy of tirzepatide, semaglutide, and liraglutidein the diet-induced obesity mouse model.

Objective: Incretin receptor agonists are now standard of care in treating obesity. Their efficacy and tolerability might be further improved by combining them with compounds that offer orthogonal mechanisms of action. The cannabinoid type 1 receptor (CB1R) is a clinically validated therapeutic target in obesity, and several experimental CB1R inverse agonists have been shown to induce weight loss.

Bedside ultrasound of the internal jugular vein to assess fluid status and right ventricular function: The POCUS-JVD study.

Background: Accurate estimation of fluid status is important in the management of heart failure patients, however, the current methods for bedside assessment can be unreliable or impractical for daily use.

Methods: Non-ventilated patients were enrolled immediately prior to scheduled right heart catheterization (RHC). Using M-mode, IJV maximum (Dmax) and minimum (Dmin) anteroposterior diameters were measured during normal breathing, while supine.

Covid-19 positive donor utilization for heart transplantation: The new frontier for donor pool expansion.

Background: Hearts from COVID-19 positive donors (CPD) are being utilized for heart transplantation by some centers; however, this is in the setting of the lack of guidelines or robust evidence. The paucity of evidence is reflected in the recent Organ Procurement and Transplantation Network (OPTN) communication describing CPD utilization as an "unknown risk."

Methods And Results: We analyzed the UNOS database for adult heart transplants performed between January 2021 to December 2022, and CPD comprised of a significant percentage of donors, being used in >10% of recipients in some UNOS regions.

Evaluation of adjusted international normalized ratio goal in patients with HeartMate 3 left ventricular assist devices.

Background: The HeartMate3 left ventricular assist device (HM3 LVAD) has shown a low incidence of thrombosis, but bleeding risk is as high as 43%. We aim to describe the impact of lower international normalization ratio (INR) goal on clinical outcomes.

Methods: In February 2019, our tertiary care institution lowered INR goal in HM3 patients from manufacturer recommendations to 1.

Patterns and outcomes of COVID-19 donor utilization for heart transplant.

Background: The outcomes following COVID-19 positive donor (CPD) utilization for heart transplant are unknown.

Methods: UNOS database was analyzed for heart transplants performed from the declaration of COVID-19 pandemic until September 30, 2022.

Result: Since the onset of pandemic, there were 9876 heart transplants reported.

Outcomes of Heart Failure in COVID-19 Patients: An Appalachian Experience.

Background: The Southeastern rural areas of the USA have a higher prevalence of heart failure (HF). Coronavirus disease 2019 (COVID-19) infection is associated with poor outcomes in patients with HF. Our study aimed to compare the outcomes of hospitalized HF patients with and without COVID-19 infection specifically in rural parts of the USA.

Retrospective review of secondary prevention strategies for gastrointestinal bleeding and associated clinical outcomes in left ventricular assist device patients.

Background: Gastrointestinal bleeding (GIB) is one of the most common bleeding complications associated with left ventricular assist devices (LVAD). Currently, there is no strong evidence or clear guidance for which secondary GIB prophylaxis strategy should be implemented after the discontinuation of aspirin.

Methods: Our single-center study describes the outcomes of 26 LVAD patients who experienced a total of 49 GIB events: these individuals were either in Group-1 (lower INR target range) or Group-2 (lower INR target plus a hemostatic agent) as the secondary prophylaxis strategy.

Lenabasum Reduces Porphyromonas gingivalis-Driven Inflammation.

The aim of this study was to evaluate the potential anti-inflammatory and anti-resorptive effects of lenabasum in the context of Porphyromonas gingivalis (Pg)-induced inflammation. Lenabasum or ajulemic acid (1',1'-dimethylheptyl-THC-11-oic-acid), a synthetic analog of THC-11-oic acid, has already demonstrated anti-inflammatory properties for the treatment of several inflammatory diseases. In vitro, the cytocompatibility of lenabasum was evaluated in human oral epithelial cells (EC), oral fibroblasts and osteoblasts by metabolic activity assay.

Ratio of Mixed Venous Oxygen Saturation-to-Pulmonary Capillary Wedge Pressure: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program.

Background: Hemodynamic values from right heart catheterization aid diagnosis and clinical decision-making but may not predict outcomes. Mixed venous oxygen saturation percentage and pulmonary capillary wedge pressure relate to cardiac output and congestion, respectively. We theorized that a novel, simple ratio of these measurements could estimate cardiovascular prognosis.

Mechanical circulatory support in pre and postheart transplant period.

Purpose Of Review: Progression of heart failure (HF) and its unpredictable and volatile nature, often requires advanced therapies including heart transplant. Mechanical circulatory support plays an integral part in the advanced treatment options. This technology can be deployed in several ways, particularly in the preparation and patient optimization for heart transplants.

COVID-19 and Heart Transplant: A Case Series and Review of the Literature.

Coronavirus disease 2019 (COVID-19) has resulted in many challenges in patient care, especially among high-risk populations such as heart transplant recipients. Patients with heart transplant experience a significantly higher mortality rate with COVID-19 infection, and management is based on extrapolation from clinical trials done on nontransplant patients and from clinical experience. Here we report 4 cases of patients with heart transplant who presented with COVID-19 infection in late 2020.

Pulmonary Arterial Hypertension: a Pharmacotherapeutic Update.

Purpose Of Review: Pulmonary arterial hypertension (PAH) leads to progressive increases in pulmonary vascular resistance (PVR), right heart failure, and death if left untreated. This review will summarize and discuss recent updates in the classification and management of patients with PAH.

Recent Findings: PAH requires careful hemodynamic assessment and is defined by a mean pulmonary artery pressure > 20 mmHg with normal left-sided filling pressures and a PVR ≥ 3 Wood units.

A "Cat"-astrophic Case of Bartonella henselae infective endocarditis followed by cardiac transplantation salvage therapy.

To our knowledge, no cases of Bartonella henselae endocarditis leading to subsequent heart transplantation salvage therapy have been published. We present a case of a 29-year-old man with cat-inflicted B henselae endocarditis and concurrent worsening heart failure, who then underwent successful heart transplantation 50 days following diagnosis. Treatment and monitoring strategies used in this patient are discussed.

Surgical Approaches in Heart Failure.

Heart failure is a progressive condition that continues to increase in both incidence and prevalence despite pharmacologic treatment. The high rate of morbidity and mortality associated with advanced heart failure has led to exploration of additional treatments, which include surgical interventions to improve outcomes. Heart transplant remains the gold standard but, because of the persistent donor shortage and increasing number of patients with advanced heart failure, mechanical circulatory support is gaining acceptance and can be used as a bridge to heart transplant for those eligible or as destination therapy.

Prognostic Role of Elevated Myeloperoxidase in Patients with Acute Coronary Syndrome: A Systemic Review and Meta-Analysis.

Background: Myocardial inflammation following acute ischemic injury has been linked to poor cardiac remodeling and heart failure. Many studies have linked myeloperoxidase (MPO), a neutrophil and inflammatory marker, to cardiac inflammation in the setting of acute coronary syndrome (ACS). However, the prognostic role of MPO for adverse clinical outcomes in ACS patients has not been well established.

In-hospital outcomes of percutaneous ventricular assist devices versus intra-aortic balloon pumps in non-ischemia related cardiogenic shock.

Introduction: This study compared inpatient outcomes related to the use of these two devices among patients who developed cardiogenic shock not due to acute myocardial infarction or coronary revascularization.

Methods: We extracted admission-level records of patients with a diagnosis of cardiogenic shock who underwent either PVAD or IABP implantation from the National Inpatient Sample (NIS) database from 2010 to 2014. Our outcomes of interest were mortality and length of stay.

Treatment of single peripheral pulmonary emboli: patient outcomes and factors associated with decision to treat.

Background: Increasing use of computed tomography pulmonary angiography together with higher-resolution scanners has increased the detection of peripheral filling defects. Physicians face the dilemma of whether to treat patients with these findings, especially single defects. The aims of this study were to compare the outcomes of treated and untreated patients with single peripheral filling defects (SPFD) and identify factors associated with treatment.
