Left ventricular assist devices (LVADs) offer a therapeutic strategy for patients with end-stage heart failure. Increased device utilization has also increased the incidence of device-related complications including gastrointestinal bleeding (GIB). Multiple mechanisms have been proposed in the pathophysiology of continuous-flow LVAD-associated GIB including physiologic changes associated with high shear and nonpulsatile flow such as gastrointestinal arteriovenous malformations and acquired von Willebrand syndrome. Strategies to minimize the morbidity and mortality of LVAD-associated GIB are needed. Octreotide, a somatostatin analogue, has been described as an adjunct to current therapies and interventions. Factors that contribute to LVAD-associated GIB may be targeted by the pharmacologic effects of octreotide, including improved platelet aggregation, increased vascular resistance, and decreased splanchnic circulation. Octreotide has demonstrated clinical benefit in several case series and clinical trials for the treatment of LVAD-associated GIB. The focus of this article will be to review the pathophysiology of LVAD-associated GIB, discuss pharmacologic and nonpharmacologic treatment modalities, and review available literature on the role of octreotide in the management of LVAD-associated GIB.

Background Impella devices are being increasingly used to manage cardiogenic shock. The incidence of thrombosis and hemolysis in patients on Impella support increases with longer durations of use, and the management of Impella thrombosis remains ill‐defined. Methods In this case series, we describe our institutional use of tissue plasminogen activator (tPA) alteplase in the Impella purge solution (0.04 or 0.08 mg/ml tPA in sterile water) for management of suspected Impella thrombosis in five patients, each with a different clinical course, treatment, and outcome. Given the limited evidence on the diagnosis of Impella thrombosis, suspicion was driven by the presence of decreased purge flow rates, increased purge pressures, and markers of hemolysis such as elevated lactate dehydrogenase and hematuria. Outcomes In all cases, tPA administration resulted in resolution of low purge flow rates and high purge pressures. No major bleeding complications were directly associated with tPA. Two patients were bridged successfully to heart transplantation, two patients underwent left ventricular assist device implantation, and one patient died after withdrawal of care. Conclusion Based on our experience, tPA administration appears to be a viable and safe salvage option to delay or prevent device exchange in the setting of suspected Impella thrombosis.

Background:Impairments in psychosocial status and cognition relate to poor clinical outcomes in patients with atrial fibrillation (AF). However, how often these conditions co-occur and associations between burden of psychosocial and cognitive impairment and quality of life (QoL) have not been systematically examined in patients with AF.Methods:A total of 218 patients with symptomatic AF were enrolled in a prospective study of AF and psychosocial factors between May 2013 and October 2014 at the University of Massachusetts Medical Center. Cognitive function, depression, and anxiety were assessed at baseline and AF-specific QoL was assessed 6 months after enrollment using validated instruments. Demographic and clinical information were obtained from a structured interview and medical record review.Results:The mean age of the study participants was 63.5 ± 10.2 years, 35% were male, and 81% had paroxysmal AF. Prevalences of impairment in 1, 2, and 3 psychosocial/cognitive domains (eg, depression, anxiety, or cognition) were 75 (34.4%), 51 (23.4%), and 16 (7.3%), respectively. Patients with co-occurring psychosocial/cognitive impairments (eg, >1 domain) were older, more likely to smoke, had less education, and were more likely to have heart failure (all P < 0.05). Compared with participants with no psychosocial/cognitive impairments, AF-specific QoL at 6 months was significantly poorer among participants with baseline impairment in 2 (B = −13.6, 95% CI: −21.7 to −5.4) or 3 (B = −15.1, 95% CI: −28.0 to −2.2) psychosocial/cognitive domains.Conclusion:Depression, anxiety, and impaired cognition were common in our cohort of patients with symptomatic AF and often co-occurred. Higher burden of psychosocial/cognitive impairment was associated with poorer AF-specific QoL.

Background: Oral direct factor Xa inhibitors (FxaIs) are renally eliminated; thus, acute kidney injury (AKI) may increase the risk for drug accumulation and bleeding. There is minimal data describing the effects of AKI on FxaI anti-Xa levels or clinical outcomes. Objective: To compare anti-Xa level monitoring with standard monitoring in patients who experience AKI on apixaban or rivaroxaban. Methods: This retrospective study included patients admitted within a large hospital system from May 2016 to October 2020. Patients were included if they received apixaban or rivaroxaban prior to AKI. Patients were stratified into 1 of 2 groups: those with anti-Xa level monitoring or those who received standard monitoring. The primary outcome was major bleeding as defined by the International Society of Thrombosis and Haemostasis. Results: A total of 196 patients were included in the final analysis. Major bleeding occurred in 2 patients who received anti-Xa level monitoring, compared with 14 patients who received standard monitoring (2.1% vs 14%; P < 0.01). Variables identified as predictors of major bleeding included a documented history of liver disease (adjusted odds ratio = 3.17; 95% CI = 1.04-9.67; P = 0.04) and antiplatelet use (adjusted odds ratio = 4.18; 95% CI = 1.28-13.7; P = 0.02). Conclusion and Relevance: This is the first study to demonstrate that anti-Xa level monitoring was associated with a significant reduction in major bleeding compared with standard monitoring in patients with AKI who received apixaban or rivaroxaban. The optimal management of antithrombotic medications in patients with AKI and recent exposure to an FxaI requires further investigation.

Background Oral factor Xa inhibitors (FXaI) can be administered in fixed doses without the need for routine laboratory monitoring. Anti-Xa assays can estimate anticoagulant effect for specific FXaI's. The aim of this study was to characterize anti-Xa levels in patients taking apixaban or rivaroxaban with major bleeding events. Methods Apixaban and rivaroxaban anti-Xa assays ordered within our hospital system from May 2016 to September 2019 were evaluated. The primary outcome was major bleeding events defined by International Society of Thrombosis and Haemostasis criteria. Median anti-Xa levels for each FXaI were calculated for those with and without major bleeding, as well as those who did and did not receive reversal agents. Results A total of 606 anti-Xa levels were analyzed. There were 146 major bleeding events documented, with the most common site being intracranial (63%). Median anti-Xa levels in patients with and without major bleeding were similar, whereas those on apixaban therapy who received reversal agents typically had higher anti-Xa levels (73 ng/mL vs. 153 ng/mL, p = 0.0019). Factors significantly associated with increased odds of bleeding were an age > 80 years, inappropriately high dosing regimens, and modest anti-Xa levels (100–300 ng/mL) for rivaroxaban specifically. Conclusions Older age and inappropriately high dosing regimens were associated with major bleeding in patients taking apixaban and rivaroxaban. Further investigation into the utility of anti-Xa levels for FXaI is warranted.

Unlabeled nebulization of opioids, lidocaine, magnesium, amphotericin B, and colistin is an alternative method of treatment for patients with pulmonary problems or infections or for those undergoing bronchoscopy. More research is needed to develop guidelines for their use since nebulization may provide benefits to many patients who otherwise cannot be treated or would be at risk of systemic adverse effects of the drugs.
