Physician's fear of anticoagulant therapy in nonvalvular atrial fibrillation.

Despite the availability of predictive tools and treatment guidelines, anticoagulant therapies are underprescribed and many patients are undertreated for conditions that predispose to thromboembolic complications, including stroke. This review explores reasons for which physicians fear that the risks of anticoagulation may be greater than the potential benefit. The results of numerous clinical trials confirm that patients benefit from judiciously managed anticoagulation and that physicians can take various approaches to minimize risk.

Racial-ethnic differences in stroke risk factors and subtypes: results of a prospective hospital-based registry.

A majority of stroke research in the United States focuses on Caucasian and African-American populations, limiting the amount of comparative stroke data available on other racial and ethnic groups. The purpose of this research was to examine differences in stroke risk factors/subtypes between minority stroke patient groups in the United States (Asian-Indian, African-American, and Hispanic), using a Caucasian reference group. All patients had a comprehensive stroke work-up to ascertain their stroke risk factors and their stroke etiology applying TOAST criteria.
