    Abstract Background: Serum lactate dehydrogenase (LDH) is the standard measure for detection of hemolysis and thus surveillance for device thrombosis in patients on continuous-flow left ventricular assist device (CF-LVAD) support. Significant hemolysis has been defined as LDH ≥600 IU/L. However, LDH testing requires phlebotomy, precluding frequent home monitoring. Simple dipstick urinalysis (UA) for urine hemoglobin (U-Hb) overcomes this limitation. This study correlated U-Hb and LDH levels and evaluated the performance of UA for detection of significant hemolysis in patients with CF-LVADs.
    Methods: U-Hb and LDH were measured concurrently 956 times in 221 patients with CF-LVADs. Statistics were computed to determine accuracy of UA in detecting LDH ≥600 IU/L, with a positive result being any detected U-Hb. All analyses were performed with and without excluding for 1) conditions associated with tissue damage, which are known to increase LDH, and 2) suspected or confirmed urinary tract infections or hematuria, which are known to cause hemoglobinuria for reasons other than hemolysis.
    Results: Mean LDH for absent/mild/severe U-Hb was 360 IU/L/467 IU/L IU/L/777 IU/L without exclusions, 354 IU/L/444 IU/L IU/L/651 IU/L after excluding non-hemolytic LDH elevations, 370 IU/L/513 IU/L IU/L/1,357 IU/L after excluding urinary tract infections and hematuria, and 367 IU/L/470 IU/L IU/L/1,217 IU/L when both exclusions applied (all p < 0.001). Absent U-Hb had a negative predictive value for LDH ≥600 IU/L of >90% for all analyses.
    Conclusions: Serum LDH is significantly associated with U-Hb levels. Absence of U-Hb appears to efficiently exclude significant hemolysis in patients with CF-LVADs. Because it can be performed by patients at home, hemoglobinuria monitoring may enable more intense surveillance and earlier diagnosis of device thrombosis.

    Abstract Background: Stroke is one of the leading complications during continuous flow-left ventricular assist device (CF-LVAD) support. Risk factors have been well described, although less is known regarding treatment and outcomes. We present a large single-center experience on stroke outcome and transplant eligibility by stroke sub-type and severity in CF-LVAD patients.
    Methods: Between January 1, 2008, and April 1, 2015, 301 patients underwent CF-LVAD (266 HeartMate II [HM I], Thoratec Corp, Pleasanton, CA; 35 HeartWare [HVAD], HeartWare International Inc, Framingham, MA). Stroke was defined as a focal neurologic deficit with abnormal neuroimaging. Intracerebral hemorrhage (ICH) definition excluded sub-dural hematoma and hemorrhagic conversion of an ischemic stroke (IS). Treatment in IS included intra-arterial embolectomy when appropriate; treatment in ICH included reversal of coagulopathy. Stroke severity was measured using the National Institutes of Health Stroke Scale (NIHSS). Outcomes were in-hospital mortality and transplant status.
    Results: Stroke occurred in 40 patients: 8 ICH (4 HM II, 4 HVAD) and 32 IS (26 HM II, 6 HVAD). Among 8 ICH patients, there were 4 deaths (50%), with NIHSS of 18.8 ± 13.7 vs 1.8 ± 1.7 in survivors (p = 0.049). Among 32 IS patients, 12 had hemorrhagic conversion and 5 were treated with intra-arterial embolectomy. There were 9 deaths (28%), with NIHSS of 16.2 ± 10.8 vs 7.0 ± 7.6 in survivors (p = 0.011). Among the 32 IS patients, 12 underwent transplant, and 1 is awaiting transplant. No ICH patients received a transplant.
    Conclusions: In-hospital mortality after stroke is significantly affected by the initial neurologic impairment. Patients with IS appear to benefit the most from in-hospital treatment and often make sufficient recovery to be able to progress to transplant.
