Efficacy and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Atrial Fibrillation Patients With Impaired Liver Function: A Retrospective Cohort Study.
    Journal of the American Heart Association, 2018, 08-07, Volume: 7, Issue:15

    Background Patients with impaired liver function ( ILF ) were excluded from clinical trials that investigated non-vitamin K antagonist oral anticoagulants ( NOAC s) for stroke prevention in patients with atrial fibrillation. The aim of this study was to evaluate the efficacy and safety of NOAC s in atrial fibrillation patients with ILF . Methods and Results A cohort study based on electronic medical records was conducted from 2009 to 2016 at a multicenter healthcare provider in Taiwan and included 6451 anticoagulated atrial fibrillation patients (aged 76.7±7.0 years, 52.5% male). Patients were classified into 2 subgroups: patients with normal liver function (n=5818) and patients with ILF (n=633, 9.8%). Cox regression analysis was performed to investigate the risks of thromboembolism, bleeding, and death associated with use of NOAC s and warfarin in patients with normal liver function and ILF , respectively. In patients with normal liver function, compared with warfarin therapy (n=2928), NOAC therapy (n=4048) was associated with significantly lower risks of stroke or systemic embolism (adjusted hazard ratio: 0.75; 95% confidence interval, 0.65-0.88; P<0.001) and death (adjusted hazard ratio: 0.69; 95% confidence interval, 0.60-0.80; P<0.001) with no difference in major bleeding or gastrointestinal bleeding. In patients with ILF , compared with warfarin therapy (n=394), NOAC therapy (n=342) was associated with significantly lower risk of death (adjusted hazard ratio: 0.64; 95% confidence interval, 0.49-0.83; P<0.001), but no difference in stroke or systemic embolism, major bleeding, or gastrointestinal bleeding. Conclusions In atrial fibrillation patients with ILF , NOAC therapy and warfarin therapy were associated with similar risks of stroke or systemic embolism, major bleeding, and gastrointestinal bleeding.

The safety of thoracentesis in patients with uncorrected bleeding risk.
    Annals of the American Thoracic Society, 2013, Volume: 10, Issue:4

    Thoracentesis is commonly performed to evaluate pleural effusions. Many medications (warfarin, heparin, clopidogrel) or physiological factors (elevated International Normalized Ratio [INR], thrombocytopenia, uremia) increase the risk for bleeding. Frequently these medications are withheld or transfusions are performed to normalize physiological parameters before a procedure. The safety of performing thoracentesis without correction of these bleeding risks has not been prospectively evaluated.. This prospective observational cohort study enrolled 312 patients who underwent thoracentesis. All patients were evaluated for the presence of risk factors for bleeding. Hematocrit levels were obtained pre- and postprocedure, and the occurrence of postprocedural hemothorax was evaluated.. Thoracenteses were performed in 312 patients, 42% of whom had a risk for bleeding. Elevated INR, secondary to liver disease or warfarin, and renal disease were the two most common etiologies for bleeding risk, although many patients had multiple potential bleeding risks. There was no significant difference in pre- and postprocedural hematocrit levels in patients with a bleeding risk when compared with patients with no bleeding risk. No patient developed a hemothorax as a result of the thoracentesis.. This single-center, observational study suggests that thoracentesis may be safely performed without prior correction of coagulopathy, thrombocytopenia, or medication-induced bleeding risk. This may reduce the morbidity associated with transfusions or withholding of medications.
