Our SEDAN score reliably assessed risk for sICH in IV thrombolysis-treated patients with anterior- and posterior circulation ischemic stroke, and it can support clinical decision making in high-risk patients. External validation of the score supports its generalization.
This databank-based, multicenter study compared all stroke patients with IV tissue plasminogen activator aged > or = 80 years (n = 38) and those < 80 years old (n = 287). Three-month mortality was higher in older patients. Favorable outcome (modified Rankin scale < or = 1) and intracranial hemorrhage (asymptomatic/symptomatic/fatal) were similarly frequent in both groups. Logistic regression showed that stroke severity, time to thrombolysis, glucose level, and history of coronary heart disease independently predicted outcome, whereas age did not.
Background and Purpose-Intravenous thrombolysis (IVT) for stroke seems to be beneficial independent of the underlying etiology. Whether this is also true for cervical artery dissection (CAD) is addressed in this study. Methods-We used the Swiss IVT databank to compare outcome and complications of IVT-treated patients with CAD with IVT-treated patients with other etiologies (non-CAD patients). Main outcome and complication measures were favorable 3-month outcome, intracranial cerebral hemorrhage, and recurrent ischemic stroke. Modified Rankin Scale score Յ1 at 3 months was considered favorable. Results-Fifty-five (5.2%) of 1062 IVT-treated patients had CAD. Patients with CAD were younger (median age 50 versus 70 years) but had similar median National Institutes of Health Stroke Scale scores (14 versus 13) and time to treatment (152.5 versus 156 minutes) as non-CAD patients. In the CAD group, 36% (20 of 55) had a favorable 3-month outcome compared with 44% (447 of 1007) non-CAD patients (OR, 0.72; 95% CI, 0.41 to 1.26), which was less favorable after adjustment for age, gender, and National Institutes of Health Stroke Scale score (OR, 0.50; 95% CI, 0.27 to 0.95; Pϭ0.03). Intracranial cerebral hemorrhages (asymptomatic, symptomatic, fatal) were equally frequent in CAD (14% [7%, 7%, 2%]) and non-CAD patients (14% [9%, 5%, 2%]; Pϭ0.99). Recurrent ischemic stroke occurred in 1.8% of patients with CAD and in 3.7% of non-CAD-patients (Pϭ0.71). Conclusion-IVT-treated patients with CAD do not recover as well as IVT-treated non-CAD patients. However, intracranial bleedings and recurrent ischemic strokes were equally frequent in both groups. Key Words: carotid artery Ⅲ cervical artery dissection Ⅲ complications Ⅲ dissection Ⅲ outcome Ⅲ thrombolysis I ntravenous thrombolysis (IVT) for acute ischemic stroke using recombinant tissue plasminogen activator has been shown to be safe and efficacious. 1,2 Treatment response seems to be independent of the underlying stroke mechanism. 3 However, whether this observation includes patients with strokes attributable to cervical artery dissection (CAD) has not been studied. CAD is characterized by intramural accumulation of blood. Theoretically, IVT might promote and increase the intramural bleeding in CAD and cause progressive hemodynamic worsening and infarct growth. In patients with stroke with aortic dissection extending to the cervical arteries, IVT might be dangerous as it is in patients with IVT for myocardial infarction. 4 -6 According to recent pilot data, the outcome of 7 IVT-treated patients with CAD tended to be worse than that of 7 patients with CAD not treated with IVT. 7 In turn, patients with CAD have not been excluded from randomized, placebo-controlled trials 1,8,9 of IVT in stroke. Treatment guidelines 10 do not advise against IVT in such patients, but randomized, placebo-controlled trial-based data about IVT versus placebo in patients with CAD are not available. Only information of case series without control groups and small sample sizes (ie, 30, 11 11, 12 6, 13 a...
BackgroundAtrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all‐cause mortality may guide interventions.Methods and ResultsIn the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF) study, patients with nonvalvular atrial fibrillation were randomized to rivaroxaban or dose‐adjusted warfarin. Cox proportional hazards regression with backward elimination identified factors at randomization that were independently associated with all‐cause mortality in the 14 171 participants in the intention‐to‐treat population. The median age was 73 years, and the mean CHADS 2 score was 3.5. Over 1.9 years of median follow‐up, 1214 (8.6%) patients died. Kaplan–Meier mortality rates were 4.2% at 1 year and 8.9% at 2 years. The majority of classified deaths (1081) were cardiovascular (72%), whereas only 6% were nonhemorrhagic stroke or systemic embolism. No significant difference in all‐cause mortality was observed between the rivaroxaban and warfarin arms (P=0.15). Heart failure (hazard ratio 1.51, 95% CI 1.33–1.70, P<0.0001) and age ≥75 years (hazard ratio 1.69, 95% CI 1.51–1.90, P<0.0001) were associated with higher all‐cause mortality. Multiple additional characteristics were independently associated with higher mortality, with decreasing creatinine clearance, chronic obstructive pulmonary disease, male sex, peripheral vascular disease, and diabetes being among the most strongly associated (model C‐index 0.677).ConclusionsIn a large population of patients anticoagulated for nonvalvular atrial fibrillation, ≈7 in 10 deaths were cardiovascular, whereas <1 in 10 deaths were caused by nonhemorrhagic stroke or systemic embolism. Optimal prevention and treatment of heart failure, renal impairment, chronic obstructive pulmonary disease, and diabetes may improve survival.Clinical Trial Registration URL: https://www.clinicaltrials.gov/.

The Vscan used by a trained cardiologist has good diagnostic accuracy in the emergency setting compared with a high-end echocardiograph, despite small screen size and lack of pulse-wave and continuous Doppler.
