Central aortic pulse pressure, thrombogenicity and cardiovascular risk
AbstractHigh central aortic pulse pressure (CPP) and thrombin-induced platelet –fibrin clot strength (TIP–FCS) have been associated with ischemic outcomes in patients with coronary artery disease in separate studies. But, the ischemic risk associated with these factors has never been analyzed in a single study and their interrelation is unknown. The primary aim of the stud y was to establish cut points for CPP and TIP–FCS measured at the time of catheterization associated with long term major adverse cardiovascular events. We enrolled 334 consecutive patients undergoing cardiac catheterization and assessed thrombogen...

Venous thromboembolism: thrombosis, inflammation, and immunothrombosis for clinicians
AbstractVenous thromboembolism (VTE) is a worldwide disease related with mortality, cardiovascular disability, impaired quality of life and, cause major long-term complications. Clinicians related to the acute and long-term patients care must be involved in the molecular mechanisms of thrombosis. The vessel wall and its inner lining of the endothelium are critical to the maintenance of a patent vasculature. After endothelial disruption, collagen (first line of endothelial defense) and intravascular tissue factor (second line of endothelial defense) are exposed to blood flow, starting the formation of a thrombus. Anticoagul...

Evaluating safety of thrombolysis in chronic kidney disease patients presenting with pulmonary embolism using propensity score matching
AbstractTo assess the safety of thrombolytic therapy in chronic kidney disease (CKD) patients who present with pulmonary embolism (PE). We used the Nationwide Inpatient Sample Database to identify patients who underwent thrombolysis for PE between 2010 and 2014. The patients were divided into two groups: (1) No CKD and (2) CKD. Patients with and without CKD were matched using 1:1 propensity score matching and a caliper width of 0.01. The primary outcomes were in-hospital mortality and hemorrhagic events. The secondary outcomes were blood transfusions, length of stay and total hospitalization charge. Two separate, multivari...

Comparison of 4 different strategies of DAPT after PCI in ACS real world population from a Northern Italy registry
AbstractAim of the study was to compare four different strategies of dual antiplatelet therapy (DAPT) in patients with acute coronary syndromes (ACS) treated with PCI. DAPT with Clopidogrel, Ticagrelor and Prasugrel has proved to be effective in patients with ACS treated with percutaneous coronary intervention (PCI) by reducing major adverse cardiovascular outcomes (MACE). However, the effect of the different strategies in a real-world population deserves further verification. A retrospective analysis of 2404 discharged ACS patients treated with PCI was performed, with a median follow-up of 1 year. The study population w...

Systemic lupus erythematosus and the risk of perioperative major adverse cardiovascular events
AbstractSystemic lupus erythematosus (SLE) is a significant risk factor for cardiovascular disease. The relationship between SLE and perioperative cardiovascular risks following non-cardiac surgery is uncertain. We investigated associations between a diagnosis of SLE and outcomes following major non-cardiac surgery in a large national database from the United States. Patients age ≥ 18 years requiring major non-cardiac surgery were identified from Healthcare Cost and Utilization Project’s National Inpatient Sample data from 2004 to 2014. Systemic lupus erythematosus and perioperative major adverse cardiovascular e...

Efficacy and safety of dabigatran in patients with atrial fibrillation scheduled for transoesophageal echocardiogram-guided direct electrical current cardioversion: a prospective propensity score-matched cohort study
This study investigated the long-term efficacy and safety of newly initiated anticoagulation with dabigatran versus uninterrupted vitamin K antagonist (VKA) therapy in patients with AF scheduled for transesophageal echocardiogram (TEE)-guided direct electrical current cardioversion (DCC). Consecutive adult patients with persistent AF scheduled to undergo DCC were included in the study. Patients received dabigatran 110 mg or 150 mg twice daily (bid) or VKA at therapeutic doses for at least 3 weeks before and 4 weeks after DCC. All patients underwent anamnestic, clinical, electrocardiographic and echocardiographic eva...

Overwork accelerates thrombotic reaction: implications for the pathogenesis of Karoshi
AbstractWork-related stressors are potential causes of cardiovascular diseases (CVDs) and stroke; however, the pathophysiological mechanisms by which occupational stress induces and exacerbates CVDs remain unclear. The global thrombosis test (GTT) is a novel in vitro assay for evaluating both thrombotic reactions and subsequent thrombolysis. The time required to form an occlusive thrombus with the GTT, called as the occlusion time (OT), and the time to lyse the thrombus, the lysis time (LT), are markers of thrombotic and thrombolytic reactions, respectively. We investigated the impact of work-related stress on the thrombot...

Cryptogenic acute limb ischemia: a retrospective cohort study defining a previously undescribed clinical entity
AbstractAcute limb ischemia (ALI) is generally secondary to cardioembolism or progression of peripheral vascular disease, however, a discrete population of patients with ALI exists in which no precipitant is ever established. Unlike cryptogenic arterial occlusion in other arenas, such as cryptogenic stroke, cryptogenic acute limb ischemia (cALI) has not been well-described, and no routine management has been established. The aim of this study is to describe patients with cALI, and the risk of recurrence based on the treatment they received. We performed a retrospective cohort study of patients evaluated for ALI at a single...

Acute agranulocytosis after oral administration of dabigatran: a rare case report and a short review of literature
AbstractThis case report describes agranulocytosis immediately after oral administration of dabigatran in a 68 years old man with atrial fibrillation (AF). Dabigatran is an oral, reversible and competitive thrombin inhibitor that has shown promising results. In patients with atrial fibrillation of RE-LY study (Randomized Evaluation of Long-Term Anticoagulant Therapy), dabigatran administered at a dose of 1 50 mg, as compared with warfarin, was associated with lower rates of stroke and systemic embolism but similar rates of major hemorrhage. Dabigatran is administered as a prodrug and the peak of the plasma concentration...

Direct oral anti-coagulants compared to vitamin-K antagonists in cardioversion of atrial fibrillation: an updated meta-analysis
AbstractPharmacological or electrical cardioversion allows immediate symptoms improvement in the setting of paroxysmal or persistent atrial fibrillation (AF), although the periprocedural risk of systemic embolism should be considered. Recently, there was a great interest on the safety and efficacy of direct oral anticoagulants (DOACs) when used for the cardioversion of non-valvular AF. We performed a random-effects meta-analysis of patients undergoing both electrical and pharmacologic cardioversion for non-valvular AF in the RE-LY, ROCKET-AF, ARISTOTLE, ENGAGE AF-TIMI 48, X-VeRT, ENSURE-AF, and EMANATE trials. We assessed ...

Prothrombin complex concentrate for reversal of direct factor Xa inhibitors prior to emergency surgery or invasive procedure: a retrospective study
AbstractDirect oral factor Xa (FXa) inhibitors are widely used for anticoagulation but a targeted antidote is not available. Four-factor prothrombin complex concentrate (4FPCC) has been shown in observational studies to support hemostasis in most patients with major bleeding related to FXa inhibitors with an acceptable rate of thromboembolic events. However, the effectiveness of 4FPCC for reversal of FXa inhibitors prior to emergency surgery or invasive procedures is unclear. A retrospective chart review was performed in patients that received 4FPCC at Hamilton General Hospital from 2015 to 2017. The primary effectiveness ...

Quality of direct oral anticoagulant prescribing in elderly patients with non-valvular atrial fibrillation: results from a large urban health system
AbstractNon-valvular atrial fibrillation (NVAF) is common in older adults. Oral anticoagulation is indicated to reduce the risk of stroke and systemic embolism, but it also poses a risk of bleeding, particularly in the elderly. Direct oral anticoagulants (DOACs) provide an alternative to warfarin and their use in the treatment of AF is growing. We conducted a retrospective cohort study to assess the quality of DOAC prescribing in elderly patients with NVAF in a large academic health system and to compare practice with consensus best practice recommendations. We searched the electronic medical record for patients ≥ 6...

Four factor prothrombin complex concentrate for warfarin reversal in patients with left ventricular assist devices
AbstractContinuous flow left ventricular assist devices (CF-LVAD) require therapeutic anticoagulation which is often interrupted for procedures or bleeding. Prior to the availability of four factor prothrombin complex concentrate (4F-PCC) in the United States, warfarin was held and its effects reversed by vitamin K or fresh frozen plasma. We evaluated the use of 4F-PCC for temporary warfarin reversal in patients with CF-LVADs and assessed outcomes. This analysis is a retrospective study of CF-LVAD patients who received 4F-PCC for warfarin reversal in the setting of bleeding or need for urgent or elective procedures. Primar...

Impact of cost on use of non-vitamin K antagonists in atrial fibrillation patients in Ontario, Canada
AbstractCanadian guidelines recommend non vitamin K antagonists (NOACs) in preference to vitamin K antagonists (VKAs) for stroke prevention in patients with atrial fibrillation (AF), but NOACs are more expensive than VKAs. Canada has a universal healthcare system that covers the cost of NOACs for select patient groups. Ability to pay for NOACs may influence their use. We reviewed medical charts of Hamilton General Hospital outpatients under the age of 65 with a new diagnosis of AF who were referred for initiation of OAC therapy. We contacted these patients by phone and asked them to complete a questionnaire regarding their...
