Calculated plasma volume status is associated with poor outcomes in acute ischemic stroke treated with endovascular treatment.

ABSTRACT:

Background and purpose

The impact of calculated plasma volume status (PVS) on the prognosis of acute ischemic stroke treated with endovascular treatment (EVT) remains undetermined. This study aimed to investigate the association between PVS and 90 days functional outcomes after EVT.

Methods

We enrolled patients treated with EVT in the anterior circulation from a prospective registry. The endpoint was a modified Rankin scale score of ≥3 points at 90 days after EVT. We used multivariable logistic regression models to investigate the association between PVS and poor outcomes. We used the restricted cubic spline to present the linearity between PVS and poor outcomes.

Results

Among the 187 enrolled patients (median age, 65 years; 35.8% women), a total of 81 patients (43.3%) experienced poor outcomes at 90 days. In multivariable analyses, PVS was associated with poor outcomes despite increasing confounding factors (odds ratio, 3.157; 95% confidence interval, 1.942-5.534; P < 0.001). The restricted cubic spline revealed a positive correlation between PVS and the risk of poor outcomes after EVT (P for nonlinearity = 0.021).

Conclusion

Our study found that an elevated PVS value was associated with poor outcomes after EVT. Further prospective cohorts were warranted to evaluate the utility of PVS in AIS treated with EVT.

Project description:The optimal method to assess fluid overload in acute respiratory distress syndrome is not known, and current techniques have limitations. Plasma volume status has emerged as a noninvasive method to assess volume status and is defined as the percentage alteration from ideal plasma volume. We hypothesized that plasma volume status would suggest the presence of significant excess volume and therefore correlate with mortality in acute respiratory distress syndrome.Design and settingThis is a retrospective cohort study of subjects enrolled in four previously completed National Heart Lung and Blood Institute-sponsored acute respiratory distress syndrome trials, using data from the National Institutes of Health Biologic Specimen and Data Repository Information Coordinating Center repository.PatientsStudy subjects included 3,165 patients with acute respiratory distress syndrome previously enrolled in National Heart Lung and Blood Institute-sponsored acute respiratory distress syndrome trials.Measurements and main resultsThe exposure variable of interest was plasma volume status, calculated as the percentage alteration of actual plasma volume calculated on the basis of weight and hematocrit using sex-specific constants. We performed Kaplan-Meier survival analysis and univariable and adjusted Cox proportional hazard models to determine the association of plasma volume status with 60-day mortality. The median age of subjects was 52 years (interquartile range, 40-63 yr). Median plasma volume status was 5.9% (interquartile range, -2.4% to 13.6%), and overall, 68% of subjects had positive plasma volume status suggesting plasma volume higher than ideal plasma volume. In adjusted models, plasma volume status greater than median was associated with 38% greater risk for mortality (hazard ratio, 1.38; 95% CI, 1.20-1.59; p < 0.001). Each interquartile range increase in plasma volume status was associated with greater mortality in adjusted models (hazard ratio, 1.24 per interquartile range increase; 95% CI, 1.13-1.36; p < 0.001). Plasma volume status greater than median was associated with fewer ventilator-free days (18 vs 19 d; p = 0.0026) and ICU-free days (15 vs 17 d; p = 0.0001).ConclusionsPlasma volume status is independently associated with mortality, ICU-free days, and ventilator-free days among subjects with acute respiratory distress syndrome. Plasma volume status could be considered for risk-stratification and to direct therapy, particularly fluid management.

Project description:Background: Evidence for the effect of subclinical thyroid dysfunction on the prognosis of patients suffering from acute ischemic stroke and receiving reperfusion therapy remains controversial. We aimed to investigate the association between subclinical thyroid dysfunction and the outcomes of patients with acute ischemic stroke who were treated with reperfusion therapy. Methods: One hundred fifty-six consecutively recruited patients with acute ischemic stroke receiving reperfusion therapy (intravenous thrombolysis, intraarterial thrombectomy and combined intravenous thrombolysis and intraarterial thrombectomy) were included in this prospective observational study. We divided patients with subclinical thyroid dysfunction into the following 2 groups and defined a euthyroid group: subclinical hyperthyroidism (a thyroid-stimulating hormone level <0.35 μU/mL), subclinical hypothyroidism (a thyroid-stimulating hormone level >4.94 μU/mL), and a euthyroid state (0.35 μU/mL ≤ thyroid-stimulating hormone level ≤ 4.94 μU/mL). Patients with overt thyroid dysfunction were excluded. The primary outcome was functional disability at 3 months (modified Rankin Scale, mRS), and the secondary outcome was successful reperfusion. A multivariate analysis was performed to evaluate the associations between subclinical thyroid dysfunction and the primary and secondary outcomes. Results: The subclinical hyperthyroidism group appeared to have poor functional outcomes, but the differences were not significant. However, compared with patients in the euthyroid state, patients with subclinical hyperthyroidism had an increased risk of poor functional outcomes at 3 months after a stroke (adjusted odds ratio [OR] 2.50, 95% confidence interval [CI] 1.01-6.14 for a mRS score of 3 to 6) and a decreased rate of successful reperfusion after reperfusion therapy (OR 0.13, 95% CI 0.04-0.43). Conclusion: Subclinical hyperthyroidism may be independently associated with a poor prognosis at 3 months and unsuccessful reperfusion in patients with acute ischemic stroke receiving reperfusion therapy.
