REACH Registry: a Global Observational Study of around 68,000 Patients in 44 Countries Who Are at High Risk of Atherothrombosis1 • Rationale • Evaluation of atherothrombosis is still limited because previous surveys have: • Focused on studying specific risk factors, or ‘single’ manifestations of the disease (e.g. heart disease) • Focused mostly on hospitalized or hospital-treated patients with stringent inclusion criteria • Been conducted in either North America or Europe 1. Bhatt DL et al, on behalf of the REACH Registry Investigators.JAMA 2006; 295(2): 180-189.
REACH Registry: a Global Observational Study of around 68,000 Patients in 44 Countries Who Are at High Risk of Atherothrombosis1 • The REACH Registry should have these added advantages: • The most globally inclusive and geographically extensive registry of patients at high risk of heart attack and stroke • Includes a broad spectrum of patient types – with or without a previous history of disease • Provides data from a ‘real world’ setting, reflecting daily practice 1. Bhatt DL et al, on behalf of the REACH Registry Investigators.JAMA 2006; 295(2): 180-189.
REACH Registry: Objectives1 Primary objectives are: Compile international data set to extend knowledge of atherothrombotic risk factors and ischemic events in the outpatient setting Provide a better understanding of the prevalence and clinical consequences of atherothrombosis in a wide range of patients from different parts of the world Important intermediate investigations have included: Assess use of risk management strategies and 18- to 24-month outcomes in a broad outpatient population encompassing various geographic regions and physician specialties 1. Ohman EM et al, on behalf of the REACH Registry Investigators.Am Heart J 2006; in press.

What do we hope the REACH Registry will achieve? REACH is the most geographically and ethnically diverse atherothrombotic population yet surveyed, providing the most accurate view to date of burden of disease and long-term prognosis for patients at high risk for atherothrombotic events With up to four years of clinical follow-up, the REACH Registry will • provide long-term insights into real-world event rates, treatment patterns and outcomes • help to improve assessment and management of stroke, heart attack and associated risk factors

REACH Registry:Baseline Results Data shown may differ slightly from published abstractsowing to a subsequent database lock
Aims of the Baseline Analysis1 • Aim: • To determine whether atherosclerosis risk factor prevalence and treatment would demonstrate comparable patterns in many countries around the world • Conclusion: • Classic cardiovascular risk factors are consistent and common, but are largely undertreated and undercontrolled in many regions of the world 1. Bhatt DL et al, on behalf of the REACH Registry Investigators.JAMA 2006; 295(2): 180-189.
REACH Registry: Conclusions From Baseline • Cardiovascular risk profiles are common and consistent across different geographic locations and patient types:1 • Treatment goals are consistently not achieved in all patient types worldwide • Established therapies are consistently underused in high-risk populations • Women are undertreated despite commonly having more severe disease2 • The REACH Registry patients with PAD have:3 • A high prevalence of concomitant disease in other vascular beds • Multiple risk factors for atherothrombosis, including pre-diabetes and undiagnosed diabetes • Underutilization of appropriate medications to treat cardiovascular risk • The REACH Registry patients with cerebrovascular disease have:4 • A high prevalence of multiple risk factors for atherothrombosis and disease in other vascular beds • Underutilization of appropriate medications 1.
