BACKGROUND: Genetic-guided pharmacotherapy (PGx) is not recommended in clinical guidelines for coronary artery disease (CAD). We aimed to examine the extent and quality of evidence from economic evaluations of PGx in CAD and to identify variables influential in changing conclusions on cost-effectiveness. METHODS AND RESULTS: From systematic searches across 6 databases, 2 independent reviewers screened, included, and rated the methodological quality of economic evaluations of PGx testing to guide pharmacotherapy for patients with CAD...

OBJECTIVES: Anticoagulants and antiplatelet (ACAP) agents are increasingly and frequently used, especially in the elderly. The present study was carried out to assess the prevalence of delayed traumatic intracranial hemorrhage (dtICH) after a normal result on an initial head computed tomography (CT) in adults who were taking ACAP medication. MATERIALS AND METHODS: The present retrospective included all adult patients who arrived in the emergency department between January 2017 and January 2021 with a history of fall from the patient's own height, while being on ACAP medication with an isolated head injury...

Patients with chronic obstructive pulmonary disease (COPD) had higher risk of atrial fibrillation (AF). The treatment of AF includes medicines to control heart rate and reduce the risk of stroke, and procedures such as cardioversion to restore normal heart rhythm. To reduce the stroke, patients with AF may prescribe some type of antithrombotic medication (such as warfarin, one of the new non-vitamin K antagonist oral anticoagulants [NOACs] - dabigitran, apixaban, rivoraxaban, or edoxaban) or maybe aspirin. The aim of our study was to exam the prescription pattern in patients with COPD and AF...

Chronic subdural hematoma (cSDH) is one of the most common types of intracranial hemorrhages, particularly in the elderly. Despite extensive research regarding cSDH diagnosis and treatment, there is conflicting data on predictors of postoperative mortality (POM). We conducted a large retrospective review of patients who underwent a cSDH evacuation at a single urban institution between 2015 and 2022. Data were collected from the electronic medical record on prior comorbidities, anticoagulation use, mental status on presentation, preoperative labs, and preoperative/postoperative imaging parameters...

Dental procedures can pose a risk of bleeding, and it is not uncommon for dentists to consult prescribing physicians regarding a mutual patient's antiplatelet and anticoagulant medication to prevent excessive bleeding during or after an upcoming procedure. However, there has been a growing controversy in the dental community surrounding the stoppage of these medications prior to dental procedures. Some believe that stopping these medications prior to dental procedures is necessary to reduce the risk of bleeding complications, while others argue that stopping them can increase the risk of stroke or other thromboembolic events...

Peri-device leak after left atrial appendage closure (LAAC) is often treated with endovascular coils, plugs, or second occluders. This is the first study reporting the Amulet device used for peri-device leak. An 80-year-old male with paroxysmal atrial fibrillation and recurrent falls with head trauma who underwent LAAC with a 24 mm Watchman 2.5 device 3 years ago at another institution was referred to our clinic for management of the peri-device leak. Transesophageal echocardiogram showed persistent residual peri-device leak with 5 mm width along the Coumadin ridge aspect of the device...

End-stage renal disease (ESRD) and atrial fibrillation (AF) are commonly encountered, with ESRD itself serving as a well-established risk factor for AF.1 The 2018 AF guidelines have recommended apixaban across all the spectrums of renal impairment, including patients on hemodialysis (HD), and the 2019 American Heart Association/American College of Cardiology/Heart Rhythm Society updated guidelines have suggested careful consideration of reduced dose of direct oral anticoagulants (DOACs) in patients with ESRD...

The monkeypox virus was still spreading in May 2022, with the first case identified in a person with travel ties to Nigeria. Using molecular docking-based techniques, we evaluated the efficiency of different bioactive chemicals obtained from plants against the monkeypox virus. A total of 56 plant compounds were evaluated for antimonekypox capabilities, with the top four candidates having a higher binding affinity than the control. We targeted the monkeypox profilin-like protein, which plays a key role in viral replication and assembly...

BACKGROUND: Bioprosthetic valve thrombosis is a complication of transcatheter aortic valve replacement (TAVR). It is believed to be platelet independent, mainly driven by contact phase activation, and more likely to be targeted by oral anticoagulant (OAC). CASE SUMMARY: We report case of an 86-year-old man with history of TAVR, who presented an early TAVR aortic valve thrombosis occurring in the context of heparin-induced thrombocytopenia (HIT) and pulmonary embolism...

Resonant Acoustic Rheometry (RAR), a newly developed ultrasound-based technique for non-contact characterization of soft viscoelastic materials, has shown promise for quantitative assessment of plasma coagulation by monitoring the entire dynamic process in real time. Here, we report the development of a multichannel RAR (mRAR) system for simultaneous monitoring of the coagulation of multiple small-volume plasma samples, a capability that is critical to efficiently provide improved assessment of coagulation...

OBJECTIVE: The natural history of endovenous glue-induced thrombus (EGIT) resolution and the role of anticoagulation (AC) and/or anti-platelet (AP) agents in their management is currently ill-defined. The goal of this investigation is to determine the clinical behavior of EGITs and whether or not AC or AP affects treatment outcomes. METHODS: We performed a retrospective review of all endovenous ablations utilizing cyanoacrylate glue (CAG) from January 2020 to December 2021 at the Center for Vein Restoration...

BACKGROUND: Prognostic significance of different anticoagulants in TBI patients remains unanswered. We aimed to compare effects of different anticoagulants on outcomes of TBI patients. METHODS: A secondary analysis of AAST BIG MIT. Blunt TBI patients ≥50 years using anticoagulants presenting ICH were identified. Outcomes were progression of ICH and need for neurosurgical intervention (NSI). RESULTS: 393 patients were identified. Mean age was 74 and most common anticoagulant was aspirin (30%), followed by Plavix (28%), and coumadin (20%)...

A man in his 30s, with a medical history of end-stage renal disease on haemodialysis three times a week after kidney transplant rejection, anaemia of inflammatory disease, hypertension, atrial fibrillation, hyperlipidaemia, subtotal parathyroidectomy and aortic valve replacement on Coumadin treatment, presented to our institution with glans penis pain. Examination of the penis revealed a painful black eschar with ulceration on the glans penis with surrounding erythema. CT scan of the abdomen and pelvis and penile Doppler ultrasound revealed calcifications of the abdominal, pelvic and penile blood vessels...

Background Dental implants are increasingly being used in the rehabilitation of the edentulous areas in the maxilla and mandible. The anterior mandible is considered a safe zone for implant placement, but clinicians often find it challenging to control bleeding in this area. This is due to the presence of the sublingual artery, which can be of varying dimensions and can cause severe bleeding. This can be of higher significance in patients with high or uncontrolled blood pressure and in patients on blood thinners like Aspirin or Coumadin where establishing a clot can be difficult...

BACKGROUND: Ethanol infusion in the vein of Marshall (EI-VOM) has the advantages of reducing the burden of atrial fibrillation (AF), decreasing AF recurrence, and facilitating left pulmonary vein isolation and mitral isthmus bidirectional conduction block. Moreover, it can lead to prominent edema of the coumadin ridge and atrial infarction. Whether these lesions will affect the efficacy and safety of left atrial appendage occlusion (LAAO) has not yet been reported. OBJECTIVES: To explore the clinical outcome of EI-VOM on LAAO during implantation and after 60 days of follow-up...

INTRODUCTION: Although the use of venous thromboembolism (VTE) chemoprophylaxis has markedly reduced VTE rates after hip fracture surgery, few studies have directly compared the efficacy of different anticoagulant agents in this setting. The purpose of this study was to compare outcomes of Lovenox, Eliquis, or Coumadin as VTE prophylaxis after hip fracture surgery. METHODS: The PearlDiver MHip national database was queried for patients older than 60 years undergoing first-time hip fracture surgery with no concurrent pelvic or distal femoral fractures...

Arterial thromboembolism is a life-threatening condition in COVID-19 patients; however, the mechanism of hypercoagulopathy remains unknown. A 62-year-old man with a history of obesity was diagnosed with COVID-19 pneumonia. After hospitalisation, unfractionated heparin was administered because of increased D-dimer levels; nevertheless, an arterial embolism in the left lower limb developed on the following day. Enhanced computed tomography revealed an occluded left iliac artery and intra-aortic thrombus at the juxtarenal level...

The use of direct oral anticoagulants (DOACs) is widely increasing in the United States (US). Warfarin has been the conventional anticoagulant used in the past few decades, but it has been gradually replaced by DOACs. The objective of the study was to analyze trends in utilization, reimbursement, and price for those anticoagulants in the US Medicaid population. Retrospective data analysis was conducted using the National Summary Files for the Medicaid State Drug Utilization Data. Study drugs included dabigatran, rivaroxaban, apixaban, edoxaban and warfarin...

BACKGROUND: In the pivotal WATCHMAN trials, warfarin was used for post-procedural anticoagulation in the first 45 days after left atrial appendage closure. We aimed to investigate the efficacy and safety of direct oral anticoagulant (DOAC) versus warfarin after WATCHMAN. METHODS: We performed a literature search of five electronic databases to identify studies comparing DOAC with warfarin after WATCHMAN. We pooled outcomes for the efficacy (thromboembolism, device-related thrombus [DRT], peri-device leak [PDL] >5mm) and safety endpoints (bleeding, mortality)...
