The STARTING-SICH is the first nomogram developed and validated in a large SITS-ISTR cohort for individualized prediction of sICH in intravenous thrombolysis-treated stroke patients.
The red blood cell distribution width (RDW) is a simple, rapid, inexpensive and straightforward hematological parameter, reflecting the degree of anisocytosis in vivo. The currently available scientific evidence suggests that RDW assessment not only predicts the risk of adverse outcomes (cardiovascular and all-cause mortality, hospitalization for acute decompensation or worsened left ventricular function) in patients with acute and chronic heart failure (HF), but is also a significant and independent predictor of developing HF in patients free of this condition. Regarding the biological interplay between impaired hematopoiesis and cardiac dysfunction, many of the different conditions associated with increased heterogeneity of erythrocyte volume (i.e., ageing, inflammation, oxidative stress, nutritional deficiencies and impaired renal function), may be concomitantly present in patients with HF, whilst anisocytosis may also directly contribute to the development and worsening of HF. In conclusion, the longitudinal assessment of RDW changes over time may be considered an efficient measure to help predicting the risk of both development and progression of HF.
An appropriate and timely management, including early diagnosis and accurate prognostication, is the mainstay for managed care of patients with acute ischemic stroke. Since red blood cell distribution width (RDW) was found to be an independent predictor of clinical outcomes in patients with thrombotic disorders, we designed a retrospective observational study to investigate whether the RDW value may also retain predictive significance in stoke patients undergoing thrombolytic therapy. This retrospective study was based on all patients admitted to the Emergency Department (ED) of the University Hospital of Verona (Italy) with a diagnosis of ischemic stroke, who underwent systemic thrombolysis between January 2013 and June 2015. The RDW value along with basal clinical characteristics was recorded at ED admission. The final study population consisted of 316 patients. A significant association was found between stroke severity (NIHSS score) and RDW ( = 0.322; < 0.001). The median RDW value in patients with clinical improvement after thrombolysis was significantly lower than in patients without (13.4 vs. 14.1%; < 0.001). The diagnostic accuracy (area under the curve) of RDW for predicting the lack of neurological improvement was 0.667. In univariate analysis, RDW >14.5% was associated with increased rate of no neurological improvement (odds ratio [OR], 2.38; 95% confidence interval [CI], 1.37-4.13), an association remaining significant also in multivariate analysis (OR, 1.85; 95% CI, 1.13-3.32). Survivor curve analysis showed that patients with RDW values ≥14.5% had a higher risk of 1-year mortality and shorter survival. These results suggest that RDW assessment at ED admission may provide valuable diagnostic and prognostic information in patients with acute ischemic stroke.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
