Real-world data of cardio-oncologic interventions for cardiovascular adverse events with oral oncolytics.

Background: Oral cancer therapy-related cardiovascular (CV) toxicity has a wide variety of presentations including arrhythmia, cardiomyopathy, and myocardial infarction, but clinical evidence related to its management is limited. The purpose of this IRB-approved, single-center, retrospective, cohort study was to characterize cardio-oncologic interventions for CV adverse events related to oral oncolytics.

Methods: The cohort included 67 patients who were admitted to a multi-hospital health system between June 1, 2016 and July 31, 2021, had at least one medical record order of oral oncolytics considered to have cardiotoxic potential, and had an ICD10 code for a cardiotoxic event added to their electronic medical records after initiation of oral oncolytics.

Patients' and physicians' beliefs and attitudes towards integrating personalized risk estimates into patient education about left ventricular assist device therapy.

Background: Personalized risk (PR) estimates may enhance clinical decision making and risk communication by providing individualized estimates of patient outcomes. We explored stakeholder attitudes toward the utility, acceptability, usefulness and best-practices for integrating PR estimates into patient education and decision making about Left Ventricular Assist Device (LVAD).

Methods And Results: As part of a 5-year multi-institutional AHRQ project, we conducted 40 interviews with stakeholders (physicians, nurse coordinators, patients, and caregivers), analyzed using Thematic Content Analysis.

Predicting Survival of End-Stage Heart Failure Patients Receiving HeartMate-3: Comparing Machine Learning Methods.

HeartMate 3 is the only durable left ventricular assist devices (LVAD) currently implanted in the United States. The purpose of this study was to develop a predictive model for 1 year mortality of HeartMate 3 implanted patients, comparing standard statistical techniques and machine learning algorithms. Adult patients registered in the Society of Thoracic Surgeons, Interagency Registry for Mechanically Assisted Circulatory Support (STS-INTERMACS) database, who received primary implant with a HeartMate 3 between January 1, 2017, and December 31, 2019, were included.

Outflow cannula alignment in continuous flow left ventricular devices is associated with stroke.

We sought to evaluate whether differences in left ventricular assist device (LVAD) canula alignment are associated with stroke. There is a paucity of clinical data on contribution of LVAD canulae alignment to strokes. We conducted a retrospective analysis of patients who underwent LVAD implantation at Houston Methodist hospital from 2011 to 2016 and included those who had undergone cardiac computed tomography (CT) with contrast.

HFSA Expert Consensus Statement on the Medical Management of Patients on Durable Mechanical Circulatory Support.

The medical management of patients supported with durable continuous flow left ventricular assist device (LVAD) support encompasses pharmacological therapies administered in the preoperative, intraoperative, postoperative, and chronic LVAD support stages. As patients live longer on LVAD support, the risks of LVAD-related complications and progression of cardiovascular and other diseases increase. Using existing data from cohort studies, registries, randomized trials, and expert opinion, this Heart Failure Society of America Consensus Document on the Medical Management of Patients on Durable Mechanical Circulatory Support offers best practices on the management of patients on durable mechanical circulatory support, focusing on pharmacological therapies administered to patients on continuous flow LVADs.

Real-World Efficacy of Tafamidis in Patients With Transthyretin Amyloidosis and Heart Failure.

Tafamidis was associated with a reduction in cardiovascular hospitalizations and all-cause mortality in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) in the ATTR-ACT trial. However, real-world data on the efficacy of tafamidis are limited. We conducted a retrospective, observational cohort study using the TriNetX research network.

Circulating hemopexin modulates anthracycline cardiac toxicity in patients and in mice.

Anthracyclines such as doxorubicin (Dox) are effective chemotherapies, but their use is limited by cardiac toxicity. We hypothesized that plasma proteomics in women with breast cancer could identify new mechanisms of anthracycline cardiac toxicity. We measured changes in 1317 proteins in anthracycline-treated patients ( = 30) and replicated key findings in a second cohort ( = 31).

Medical Therapy for Heart Failure with Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) is a challenging disease state that has long been plagued by heterogeneity in diagnostic criteria and underlying etiologies. Due in part to the complexity of defining this disease and the simplistic approach of only studying medications that have shown significant improvement in heart failure with reduced ejection fraction, there have been a multitude of negative trials in this population. In the past few years, however, there have been medications that have finally shown to benefit patients with HFpEF.

Tissue plasminogen activator in left ventricular assist device-related intravascular hemolysis after failed augmented anticoagulation.

Objectives: We sought to examine the efficacy and safety of adding fibrinogen-guided low-dose multi-day Alteplase™ tissue plasminogen activator (tPA) in the management of intravascular hemolysis (IVH) in patients with the HeartMate II (HM-II) continuous flow (CF) left ventricular assist device (LVAD) who failed to achieve IVH resolution with conventional augmented anticoagulation (AAC).

Background: IVH in patients with LVAD is often treated with AAC, failing which pump exchange is considered. We hypothesized that a trial of low-dose tPA after failed AAC therapy could resolve IVH and prevent pump exchange in some patients.

TTR variants in patients with dilated cardiomyopathy: An investigation of the DCM Precision Medicine Study.

Purpose: The cardiac phenotype of hereditary transthyretin amyloidosis (hTTR) usually presents as a restrictive or hypertrophic cardiomyopathy, and, although rarely observed as dilated cardiomyopathy (DCM), TTR is routinely included in DCM genetic testing panels. However, the prevalence and phenotypes of TTR variants in patients with DCM have not been reported.

Methods: Exome sequences of 729 probands with idiopathic DCM were analyzed for TTR and 35 DCM genes.

Future Directions in Cardiac Amyloidosis.

Just a few years ago, cardiac amyloidosis (CA) was rarely diagnosed. With poor treatment options and delayed and infrequent diagnoses, most patients who were eventually recognized to have CA were referred for hospice care. Now, the availability of sponsored genetic testing, increased use of nuclear scintigraphy, and widespread recognition have contributed to an increasing number of patients being diagnosed with transthyretin amyloid cardiomyopathy (ATTR-CM).

Cardiovascular Risks with Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitors and Monoclonal Antibody Therapy.

Purpose Of Review: Tyrosine kinase inhibitors (TKI) and monoclonal antibodies (mAbs) that target the epidermal growth factor receptor (EGFR) have changed the therapeutic landscape across a range of solid malignancies. However, there is little data regarding the cardiovascular (CV) impact of these agents. The purpose of this review is to discuss reported CV effects, pathophysiology, pre-treatment screening, diagnostic workup, and treatment recommendations in this patient population.

State-of-the-art review on management of end-stage heart failure in amyloidosis: transplant and beyond.

Cardiac involvement occurs in light-chain (AL), transthyretin wild-type (wtATTR), and hereditary (hATTR) amyloidosis; other types of amyloidosis account for < 5% of all cardiac amyloidosis (CA). CA can present subclinically on screening, insidiously with symptoms such as exertional dyspnea, or abruptly as cardiogenic shock. Initially, CA patients were thought to be poor candidates for transplant due to short long-term survival; however, there is a marked improvement in heart and multi-organ transplant outcomes over the past 10 years with newer treatments and improvements in support with temporary and durable mechanical circulatory support while awaiting transplant.

Pre-operative sarcopenia is predictive of recurrent gastrointestinal bleeding on left ventricular assist device support: A multicenter analysis.

Introduction: Whether pre left ventricular assist device (LVAD) sarcopenia is associated with higher incidence of gastrointestinal bleeding (GIB) on LVAD support remains unknown.

Methods: To study the association between preoperative sarcopenia and post LVAD GIB events, we performed a retrospective, multi-centered study including patients with chest CTs performed ≤ 3 months prior to LVAD implantation at the University of Minnesota (n = 143) and Houston Methodist Hospital (n = 133). To quantify sarcopenia, unilateral pectoralis muscle mass indexed to body surface area (PMI) and attenuation (approximated by mean Hounsfield units; PHU) were measured on pre-operative chest CT scans.

Degree of change in right ventricular adaptation measures during axillary Impella support informs risk stratification for early, severe right heart failure following durable LVAD implantation.

Risk assessment for early, severe right heart failure (RHF) after LVAD implantation remains imperfect. We sought to define the differences in RV adaptation and load after axillary Impella support between patients who experienced RHF and those who did not. Seventeen of 18 patients included were deemed intermediate or high risk for RHF by EUROMACS-RHF score.

Intravenous immunoglobulin in heart transplant recipients with mild to moderate hypogammaglobulinemia and infection.

Background: Hypogammaglobulinemia (HGG) is a complication of solid organ transplantation leading to increased risk of infections. Intravenous immunoglobulin G (IVIG) replacement in patients with HGG may be able to reduce risk and morbidity associated with infection; however, there is scarce data about IVIG in mild to moderate HGG (IgG 400-700 mg/dl) and heart transplant recipients.

Methods: A single center, retrospective study was performed in heart transplant recipients with mild (IgG 500-700 mg/dl) to moderate (IgG 400-499 mg/dl) HGG in the presence of an infection.
