Item Acute Ischemic Stroke, Depressed Left Ventricular Ejection Fraction, and Sinus Rhythm: Prevalence and Practice Patterns(American Heart Association, 2022) Baker, Anna D.; Schwamm, Lee H.; Sanborn, Danita Y.; Furie, Karen; Stretz, Christoph; Grory, Brian Mac; Yaghi, Shadi; Kleindorfer, Dawn; Sucharew, Heidi; Mackey, Jason; Walsh, Kyle; Flaherty, Matt; Kissela, Brett; Alwell, Kathleen; Khoury, Jane; Khatri, Pooja; Adeoye, Opeolu; Ferioli, Simona; Woo, Daniel; Martini, Sharyl; De Los Rios La Rosa, Felipe; Demel, Stacie L.; Madsen, Tracy; Star, Michael; Coleman, Elisheva; Slavin, Sabreena; Jasne, Adam; Mistry, Eva A.; Haverbusch, Mary; Merkler, Alexander E.; Kamel, Hooman; Schindler, Joseph; Sansing, Lauren H.; Faridi, Kamil F.; Sugeng, Lissa; Sheth, Kevin N.; Sharma, Richa; Neurology, School of MedicineBackground: There are limited data about the epidemiology and secondary stroke prevention strategies used for patients with depressed left ventricular ejection fraction (LVEF) and sinus rhythm following an acute ischemic stroke (AIS). We sought to describe the prevalence of LVEF ≤40% and sinus rhythm among patients with AIS and antithrombotic treatment practice in a multi-center cohort from 2002 to 2018. Methods: This was a multi-center, retrospective cohort study comprised of patients with AIS hospitalized in the Greater Cincinnati Northern Kentucky Stroke Study and 4 academic, hospital-based cohorts in the United States. A 1-stage meta-analysis of proportions was undertaken to calculate a pooled prevalence. Univariate analyses and an adjusted multivariable logistic regression model were performed to identify demographic, clinical, and echocardiographic characteristics associated with being prescribed an anticoagulant upon AIS hospitalization discharge. Results: Among 14 338 patients with AIS with documented LVEF during the stroke hospitalization, the weighted pooled prevalence of LVEF ≤40% and sinus rhythm was 5.0% (95% CI, 4.1-6.0%; I2, 84.4%). Of 524 patients with no cardiac thrombus and no prior indication for anticoagulant who survived postdischarge, 200 (38%) were discharged on anticoagulant, 289 (55%) were discharged on antiplatelet therapy only, and 35 (7%) on neither. There was heterogeneity by site in the proportion discharged with an anticoagulant (22% to 45%, P<0.0001). Cohort site and National Institutes of Health Stroke Severity scale >8 (odds ratio, 2.0 [95% CI, 1.1-3.8]) were significant, independent predictors of being discharged with an anticoagulant in an adjusted analysis. Conclusions: Nearly 5% of patients with AIS have a depressed LVEF and are in sinus rhythm. There is significant variation in the clinical practice of antithrombotic therapy prescription by site and stroke severity. Given this clinical equipoise, further study is needed to define optimal antithrombotic treatment regimens for secondary stroke prevention in this patient population.Item Sex-specific stroke incidence over time in the Greater Cincinnati/Northern Kentucky Stroke Study(Wolters Kluwer, 2017-09-05) Madsen, Tracy E.; Khoury, Jane; Alwell, Kathleen; Moomaw, Charles J.; Rademacher, Eric; Flaherty, Matthew L.; Woo, Daniel; Mackey, Jason; La Rosa, Felipe De Los Rios; Martini, Sharyl; Ferioli, Simona; Adeoye, Opeolu; Khatri, Pooja; Broderick, Joseph P.; Kissela, Brett M.; Kleindorfer, Dawn; Neurology, School of MedicineOBJECTIVE: Recent data suggest stroke incidence is decreasing over time, but it is unknown whether incidence is decreasing in women and men to the same extent. METHODS: Within our population of 1.3 million, all incident strokes among residents ≥20 years old were ascertained at all hospitals during July 1993-June 1994 and calendar years 1999, 2005, and 2010. A sampling scheme was used to ascertain out-of-hospital cases. Sex-specific incidence rates per 100,000 among black and white participants, age- and race-adjusted, were standardized to the 2000 US Census population. Trends over time by sex were compared; a Bonferroni correction was applied for multiple comparisons. RESULTS: Over the 4 study periods, there were 7,710 incident strokes; 57.2% (n = 4,412) were women. Women were older than men (mean ± SE 72.4 ± 0.34 vs 68.2 ± 0.32, p < 0.001). Incidence of all strokes decreased over time in men (263 [confidence interval 246-281] to 192 [179-205], p < 0.001) but not in women (217 [205-230] to 198 [187-210], p = 0.15). Similar sex differences were seen for ischemic stroke (men, 238 [223-257] to 165 [153-177], p < 0.01; women, 193 [181-205] to 173 [162-184], p = 0.09). Incidence of all strokes and of ischemic strokes was similar between women and men in 2010. Incidence of intracerebral hemorrhage and subarachnoid hemorrhage were stable over time in both sexes. CONCLUSIONS: Decreases in stroke incidence over time are driven by a decrease in ischemic stroke in men. Contrary to previous study periods, stroke incidence rates were similar by sex in 2010. Future research is needed to understand why the decrease in ischemic stroke incidence is more pronounced in men.
