Background-Stroke incidence is greater in blacks than in whites; data on Hispanics are limited. Comparing subtype-specific ischemic stroke incidence rates may help to explain race-ethnic differences in stroke risk. The aim of this population-based study was to determine ischemic stroke subtype incidence rates for whites, blacks, and Hispanics living in one community. Methods and Results-A comprehensive stroke surveillance system incorporating multiple overlapping strategies was used to identify all cases of first ischemic stroke occurring between July 1, 1993, and June 30, 1997, in northern Manhattan. Ischemic stroke subtypes were determined according to a modified NINDS scheme, and age-adjusted, race-specific incidence rates calculated. The annual age-adjusted incidence of first ischemic stroke per 100 000 was 88 (95% CI, 75 to 101) in whites, 149 (95% CI, 132 to 165) in Hispanics, and 191 (95% CI, 160 to 221) in blacks. Among blacks compared with whites, the relative rate of intracranial atherosclerotic stroke was 5.85 (95% CI, 1.82 to 18.73); extracranial atherosclerotic stroke, 3.18 (95% CI, 1.42 to 7.13); lacunar stroke, 3.09 (95% CI, 1.86 to 5.11); and cardioembolic stroke, 1.58 (95% CI, 0.99 to 2.52). Among Hispanics compared with whites, the relative rate of intracranial atherosclerotic stroke was 5.00 (95% CI, 1.69 to 14.76); extracranial atherosclerotic stroke, 1.71 (95% CI, 0.80 to 3.63); lacunar stroke, 2.32 (95% CI, 1.48 to 3.63); and cardioembolic stroke, 1.42 (95% CI, 0.97 to 2.09). Conclusions-The high ischemic stroke incidence among blacks and Hispanics compared with whites is due to higher rates of all ischemic stroke subtypes.
Patients with lateropulsion following stroke have a lower FIM efficiency and more dependency at discharge when compared with matched controls with equal functional limitations. Secondary analyses show worse outcomes for the subgroup of patients with right hemisphere stroke; lateropulsion and greater leg weakness may account for differences. Patients with lateropulsion may require longer rehabilitation to reach outcome goals.
The metabolic syndrome (MetS) is a distinctive phenotype associated with an increased risk of vascular disease. Carotid plaque is a surrogate marker of subclinical atherosclerosis and a powerful predictor of vascular outcomes. The relationship between the MetS and subclinical atherosclerosis in multiethnic populations has not been well characterized. The authors have evaluated the association of the MetS with subclinical atherosclerosis among 1895 community residents from the Northern Manhattan Study (mean age, 68.0+/-9.7 years; 59% women; 25% black; 22% white; 51% Hispanic). The prevalence of the MetS was 41% (35% in men, 45% in women), and 57% of subjects had carotid plaque. In a multivariate-adjusted logistic regression model, the MetS was a significant predictor of plaque presence (odds ratio, 1.36; 95% confidence interval, 1.10-1.67). Additionally, the number of MetS components was significantly associated with plaque prevalence. Further studies are needed to understand the role of the MetS in the progression from subclinical to clinical atherosclerotic disease.
<i>Background:</i> Dietary fat intake is associated with coronary heart disease risk, but the relationship between fat intake and ischemic stroke risk remains unclear. We hypothesized that total dietary fat as part of a Western diet is associated with increased risk of ischemic stroke. <i>Methods:</i> As part of the prospective Northern Manhattan Study, 3,183 stroke-free community residents over 40 years of age underwent evaluation of their medical history and had their diet assessed by a food-frequency survey. Cox proportional hazard models calculated risk of incident ischemic stroke. <i>Results:</i> The mean age of participants was 69 years, 63% were women, 21% were white, 24% black and 52% Hispanic. During a mean of 5.5 years of follow-up, 142 ischemic strokes occurred. After adjusting for potential confounders, risk of ischemic stroke was higher in the upper quintile of total fat intake compared to the lowest quintile (HR 1.6, 95% CI 1.0–2.7). Total fat intake >65 g was associated with increased risk of ischemic stroke (HR 1.6, 95% CI 1.2–2.3). Risk was attenuated after controlling for caloric intake. <i>Conclusions:</i> The results suggest that increased daily total fat intake, especially above 65 g, significantly increases risk of ischemic stroke.
Background and Purpose: Continued smoking after stroke is associated with a high risk of stroke recurrence and other cardiovascular disease. We sought to comprehensively understand the epidemiology of smoking cessation in stroke survivors in the United States. Furthermore, we compared smoking cessation in stroke and cancer survivors because cancer is another smoking-related condition in which smoking cessation is prioritized. Methods: We performed a cross-sectional analysis of data from the Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance System, an annual, nationally representative health survey. Using pooled data from 2013 to 2019, we identified stroke and cancer survivors with a history of smoking. We used survey procedures to estimate frequencies and summarize quit ratios with attention to demographic and geographic (state-wise and rural-urban) factors for stroke survivors. The quit ratio is conventionally defined as the proportion of ever smokers who have quit. Then, we used multivariable logistic regression to compare quit ratios in stroke and cancer survivors while adjusting for demographics and smoking-related comorbidities. Results: Among 4 434 604 Americans with a history of stroke and smoking, the median age was 68 years (interquartile range, 59–76), and 45.4% were women. The overall quit ratio was 60.8% (95% CI, 60.1%–61.6%). Quit ratios varied by age group, sex, race and ethnicity, and several geographic factors. There was marked geographic variation in quit ratios, ranging from 48.3% in Kentucky to 71.5% in California. Furthermore, compared with cancer survivors, stroke survivors were less likely to have quit smoking (odds ratio, 0.72 [95% CI, 0.67–0.79]) after accounting for differences in demographics and smoking-related comorbidities. Conclusions: There were considerable demographic and geographic disparities in smoking quit ratios in stroke survivors, who were less likely to have quit smoking than cancer survivors. A targeted initiative is needed to improve smoking cessation for stroke survivors.
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.
