Valproic Acid for Hyperactive Delirium and Agitation in Critically Ill Patients.

Background: Delirium and agitation are common syndromes in critically ill patients. Valproic acid (VPA) has shown benefit in intensive care unit (ICU)-associated delirium and agitation, but further evaluation is needed.

Objective: The purpose of this study was to evaluate the effectiveness and safety of VPA for hyperactive delirium and agitation in critically ill adult patients.

Balancing the Interactions: Assessing Antiplatelet and Antiretroviral Therapy Drug-Drug Interactions in People Living with HIV.

The clinical effect of drug-drug interactions (DDIs) between antiplatelets and antiretrovirals (ART) on bleeding, thrombosis, and other major adverse cardiovascular events (MACE) is unknown. The objective of this retrospective study was to assess the incidence of DDI at P2Y12 inhibitor (P2Y12inh) initiation and the effect of DDI on patient outcomes. Adult people living with human immunodeficiency virus (PLWH; HIV) receiving ART newly initiated on an oral P2Y12inh were included.

Bivalirudin versus heparin in patients undergoing percutaneous coronary intervention in acute coronary syndromes.

Introduction: Data on outcomes between unfractionated heparin and bivalirudin anticoagulation during percutaneous coronary intervention (PCI) in acute coronary syndromes (ACS) remains inconclusive. We aimed to systematically analyze PCI outcomes comparing unfractionated heparin and bivalirudin.

Methods: We systematically searched Ovid MEDLINE, Ovid Embase, Ovid Cochrane Database of Systematic Reviews, Scopus, and Web of Science from database inception in 1966 through January 2024 for studies evaluating PCI outcomes comparing unfractionated heparin and bivalirudin.

Evaluating the Use of Unfractionated Heparin with Intra-Aortic Balloon Counterpulsation.

Background: Evidence supporting anticoagulation with unfractionated heparin (UFH) in patients with an intra-aortic balloon pump (IABP) to prevent limb ischaemia remains limited, while bleeding risks remain high. Monitoring heparin in this setting with anti-factor Xa (anti-Xa) is not previously described.

Objectives: The study objective is to describe the incidence of thromboembolic and bleeding events with the use of UFH in patients with an IABP utilising monitoring with both anti-Xa and activated partial thromboplastin time (aPTT).

Development and external validation of a dynamic risk score for early prediction of cardiogenic shock in cardiac intensive care units using machine learning.

Aims: Myocardial infarction and heart failure are major cardiovascular diseases that affect millions of people in the USA with morbidity and mortality being highest among patients who develop cardiogenic shock. Early recognition of cardiogenic shock allows prompt implementation of treatment measures. Our objective is to develop a new dynamic risk score, called CShock, to improve early detection of cardiogenic shock in the cardiac intensive care unit (ICU).

Antithrombotic Stewardship: Evaluation of Platelet Reactivity-Guided Cangrelor Dosing Using the VerifyNow Assay.

Cangrelor may be used as a bridge when temporary interruption of dual antiplatelet therapy is necessary. However, the optimal dose and monitoring of cangrelor in patients remains unknown, especially in the setting of mechanical circulatory support (MCS). We conducted an observational, single-center, retrospective cohort study of patients who had percutaneous coronary intervention within 3 months and received cangrelor while admitted to any intensive care unit.

Anticoagulant prescribing patterns in patients with primary central nervous system malignancies and secondary metastases.

To evaluate the safety of direct oral anticoagulants (DOACs) versus low-molecular weight heparin (LMWH) in patients with central nervous system (CNS) malignancies and secondary metastases. All adult patients with CNS malignancies and secondary metastases who were treated with a DOAC or LMWH for any indication from 2018 to 2022 were included. The primary outcome was the incidence of any intracranial hemorrhage (ICH) after anticoagulation initiation.

To cool or not to cool: Targeted temperature management to prevent ventricular tachycardia associated with Brugada syndrome.

Key Clinical Message: A robust inflammatory and febrile response from acute viral illness such as with SARS-CoV-2 in patients with Brugada syndrome may lead to triggering of ventricular arrhythmias. The use of targeted temperature management (TTM) using cooling devices may mitigate the febrile triggering of ventricular arrhythmias in patients with Brugada syndrome.

Abstract: Brugada syndrome (BrS) is an autosomonal dominant genetic disorder, with a risk of ventricular tachycardia (VT).

To PLEX or Not to PLEX for Amiodarone-Induced Thyrotoxicosis.

Amiodarone-induced thyrotoxicosis (AIT) carries significant cardiovascular morbidity. There are two types of AIT with treatment including antithyroid medications and corticosteroids and treatment of ventricular arrhythmias. Therapeutic plasma exchange (TPE) also known as "PLEX" may help remove thyroid hormones and amiodarone.

Anti-factor Xa as the preferred assay to monitor heparin for the treatment of pulmonary embolism.

Introduction: The mainstay of acute pulmonary embolism (PE) treatment is anticoagulation. Timely anticoagulation correlates with decreased PE-associated mortality, but the ability to achieve a therapeutic activated partial thromboplastin time (aPTT) with unfractionated heparin (UFH) remains limited. Although some institutions have switched to a more accurate and reproducible test to assess for heparin's effectiveness, the anti-factor Xa (antiXa) assay, data correlating a timely therapeutic antiXa to PE-associated clinical outcomes remains scarce.

Antithrombotic and hemostatic stewardship: Evaluation of romiplostim for treatment of thrombocytopenia at a large academic medical center.

Romiplostim is indicated for immune thrombocytopenia (ITP), though is often used off-label for other indications such as chemotherapy-induced thrombocytopenia (CIT) and thrombocytopenia post hematopoietic stem cell transplantation (HSCT). Although romiplostim is FDA approved at a starting dose of 1 mcg/kg, it is often initiated at 2-4 mcg/kg depending on the severity of thrombocytopenia in clinical practice. Given the limited data, but interest in higher doses of romiplostim for indications other than ITP, we aimed to assess our inpatient romiplostim utilization at NYU Langone Health.

To Measure or Not to Measure: Direct Oral Anticoagulant Laboratory Assay Monitoring in Clinical Practice.

The need for therapeutic drug monitoring of direct oral anticoagulants (DOACs) remains an area of clinical equipoise. Although routine monitoring may be unnecessary given predictable pharmacokinetics in most patients, there may be altered pharmacokinetics in those with end organ dysfunction, such as those with renal impairment, or with concomitant interacting medications, at extremes of body weight or age, or in those with thromboembolic events in atypical locations. We aimed to assess real-world practices in situations in which DOAC drug-level monitoring was used at a large academic medical center.

Off-Target Effects of Cancer Therapy on Development of Therapy-Induced Arrhythmia: A Review.

Background: Advances in cancer therapeutics have improved overall survival and prognosis in this patient population; however, this has come at the expense of cardiotoxicity including arrhythmia.

Summary: Cancer and its therapies are associated with cardiotoxicity via several mechanisms including inflammation, cardiomyopathy, and off-target effects. Among cancer therapies, anthracyclines and tyrosine kinase inhibitors (TKIs) are particularly known for their pro-arrhythmia effects.

Real world prescribing practices of apixaban or rivaroxaban lead-in doses for the treatment of venous thromboembolism in hospitalized patients.

The oral factor Xa inhibitors (OFXAi) apixaban and rivaroxaban are increasingly utilized for the treatment of venous thromboembolism (VTE) with recommended initial higher dose 7- and 21-day lead-in regimens, respectively. In patients receiving initial parenteral anticoagulation, it remains unknown if the full recommended higher dose OFXAi lead-in regimens are warranted, or if days can be subtracted. We aimed to describe when clinicians may deviate from recommended lead-in durations and evaluate clinical outcomes in these scenarios.

Antithrombotic management for Impella temporary ventricular assist devices: An analysis of an academic health-system experience.

The use of acute mechanical circulatory support (MCS) has increased over the last decade. For patients with left-ventricular failure, an Impella (Abiomed, Danvers, MA) may be used to improve cardiac output. The purpose of this study is to describe Impella anticoagulation patterns and evaluate the safety and effectiveness of our protocol.

Direct oral anticoagulants versus warfarin in people living with human immunodeficiency virus.

Human immunodeficiency virus (HIV) is associated with increased rates of cardiovascular disease and vascular events, and people living with HIV (PLWH) may often have indications for therapeutic anticoagulation. However, the ideal anticoagulant in PLWH remains unknown. This retrospective cohort evaluated the tolerability and effectiveness of oral anticoagulants in PLWH.
