couple是什么意思Stroke remains a major healthcare problem. Its human and economic toll is staggering. Approximately 795 000 people in the United States have a stroke each year, of which about 610 000 are a first attack; and 6.4 million Americans are stroke survivors.1 Stroke is also estimated to result in 134 000 deaths annually and is the third leading cau of death in the nation behind heart dia and cancer. Progress has been made in reducing deaths from stroke. Along with other healthcare organizations, the American Heart Association (AHA) t the goal of decreasing cardiovascular and stroke mortality by 25% over 10 years. Between 1996 and 2006 the death rate for stroke fell by 33.5%, with the total number of stroke deaths declining by 18.4%.1 The goal of a 25% reduction was exceeded in 2008. The declines in stroke death rates, however, were greater in men than in women (age-adjusted male-to-female ratio decreasing from 1.11 to 1.03). Despite overall declines in stroke deaths, stroke incidence may be increasing. From 1988 to 1997 the age-adjusted stroke hospitalization rate grew 18.6% (from 560 to 664 per 10 000), while the total number of stroke hospitalizations incread 38.6% (from 592 811 to 821 760 annually). In 2010, the

laoscost of stroke is estimated at $73.7 billion (direct and indirect costs), with a mean lifetime cost estimated at $140 048. Stroke is also a leading cau of functional impairments, with 20% of survivors requiring institutional care after months and 15% to 30% being permanently disabled. Stroke is a life-changing event that affects not only stroke patients themlves but their family members and caregivers as well. Utility analys show that a major stroke is viewed by more than half of tho at risk as being wor than death. Despite the advent of treatment of lected patients with acute ischemic stroke with intravenous tissue-type plasminogen activator and the promi of other acute therapies, effective prevention remains the best approach for reducing the burden of stroke. Primary prevention is particularly important becau 77% of strokes are first events. The age-specific incidence of major stroke in Oxfordshire, United Kingdom, fell by 40% over a 20-year period with incread u of preventive treatments and general reductions in risk factors. Tho who practice a healthy lifestyle have an 80% lower risk of a first stroke compared with tho who do not. As discusd in detail in the ctions that follow, persons at high risk for or prone to stroke can now be identified and targeted for specific interventions.
area是什么意思This guideline provides an overview of the evidence on various established and emerging stroke risk factors and reprents a complete revision of the 2006 statement on this topic. One important change is the broader scope of this new guideline.Whereas the 2006 statement focud on ischemic stroke, becau of the overlap of risk factors and prevention strategies, this guideline also address hemorrhagic stroke, primarily focusing on an individual patient– oriented approach to stroke prevention. This contrasts with a population-bad approach in which “…the entire distribution of risk factors in the population is shifted to lower levels through population-wide interventions” and is reflected in the AHA statement on improving cardiovascular health at the community level.
