Background and Purpose Ventricular assist devices (VADs) have advanced the management of end-stage heart failure. However, these devices are associated with hemorrhagic and thrombotic complications, including stroke. We assessed the incidence, risk factors, and outcomes of ischemic and hemorrhagic stroke after VAD placement. Methods Using administrative claims data from acute care hospitals in California, Florida, and New York from 2005–2013, we identified patients who underwent VAD placement, defined by International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code 37.66. Ischemic and hemorrhagic strokes were identified by previously validated coding algorithms. We used survival statistics to determine incidence rates and Cox proportional hazard analyses to examine associations. Results Among 1,813 patients, we identified 201 ischemic strokes and 116 hemorrhagic strokes during 3.4 (±2.0) years of follow-up after implantation of a VAD. The incidence of stroke was 8.7% per year (95% confidence interval [CI], 7.7–9.7%). The annual incidence of ischemic stroke (5.5%; 95% CI, 4.8–6.4%) was nearly double that of hemorrhagic stroke (3.1%; 95% CI, 2.6–3.8%). Women faced a higher hazard of stroke than men (hazard ratio [HR], 1.6; 95% CI, 1.2–2.1), particularly hemorrhagic stroke (HR, 2.2; 95% CI, 1.4–3.4). Stroke was strongly associated with subsequent in-hospital mortality (HR, 6.1; 95% CI, 4.6–7.9). Conclusions The incidence of stroke after VAD implantation was 8.7% per year, and incident stroke was strongly associated with subsequent in-hospital mortality. Notably, ischemic stroke occurred at nearly twice the rate of hemorrhagic stroke. Women appeared to face a higher risk for hemorrhagic stroke than men.

Background and Aim Portal vein thrombosis (PVT) is increasingly common in cirrhotics, but its impact on mortality and outcomes is unclear. Studies evaluating PVT have been limited by small sample size. This study analyzes the trend of the prevalence of PVT and its associated mortality in hospitalized decompensated cirrhotics. Methods The Nationwide Inpatient Sample, the largest nationally representative database of hospital discharges, was queried from 1998 to 2014. Inpatients older than 18 years with decompensated cirrhosis were included, while those who received liver transplantation or had hepatocellular carcinoma were excluded. The primary outcomes were the trend in prevalence and associated mortality with PVT. Secondary outcomes included identifying risk factors of PVT and the effect of PVT on complications of portal hypertension. Multivariable logistic regression evaluated the outcomes. Results A total of 3 045 098 discharges were included, of which 1.5% had PVT. PVT prevalence increased from 0.7% to 2.4%, annual percent change of 9%. Mortality associated with PVT declined from 11.9% to 9.1%, annual percent change of −3.0%. In multivariable analysis controlling for factors associated with mortality in cirrhotics, PVT was associated with an increased risk of mortality (OR 1.12, P < 0.001). Multivariable logistic regression also demonstrated that PVT significantly increased the risk of acute kidney injury (OR 1.75, P < 0.001) and hepatorenal syndrome (OR 1.62, P < 0.001). Conclusions The prevalence of PVT is increasing while its associated mortality is decreasing. However, PVT still is associated with risk of mortality and kidney injury, implying a significant impact on cirrhotic outcomes.
