T he launch of Circulation: Cardiovascular Quality and Outcomes occurs during a time in which the healthcare system is simultaneously achieving its greatest triumphs and facing its most daunting challenges. As a profession, we are manifesting remarkable advances in our ability to understand, prevent, and treat cardiovascular disease and stroke, yet there are vast gaps in our ability to preempt, mitigate, and cure these conditions. Often, these gaps derive from a lack of evidence about how best to provide care and public health interventions, how best to prioritize resources, and how best to work collaboratively with and in the best interests of the public and our patients.Scholarship is needed to promote improvements in cardiovascular and stroke health and health care, focusing on the end results of our efforts. Outcomes research provides evidence to support efforts to achieve safe, effective, efficient, equitable, timely, and patient-centered care. 1 We envision the journal as a venue for content of consequence-a home for outstanding science, commentary, and novel ideas. The journal will be a catalyst for good science with practical implications and a means to inspire junior people to engage in scholarly activities that have practical applicability.The mission of Circulation: Cardiovascular Quality and Outcomes is to improve clinical decision making, population health, and healthcare policy. Moreover, Circulation: Cardiovascular Quality and Outcomes aspires to play a leading role in strengthening the global community dedicated to eliminating the epidemic of cardiovascular disease and stroke. This will be accomplished through a format that promotes scholarship, education, and constructive debate. The audience for this journal includes researchers, clinicians, policymakers, administrators, health plan executives, and government agency professionals.The journal's name is noteworthy. As part of the Circulation family, it occupies a place within a strong tradition of excellence and an association with the American Heart Association (AHA) and with the American Stroke Association. The term Quality and Outcomes is intended to convey our interest in how care and preventive strategies are delivered and what is achieved for patients and the public. The journal will be a home for contributions that span epidemiology, clinical epidemiology, management sciences, economics, statistics, health policy, quality improvement, and other fields. The publications will have a common link to practical importance, with the possibility of informing practice and policy.For the cardiovascular and stroke community, this journal completes the quartet of initiatives at the AHA to support the growth and development of outcomes research and to elevate the quality of cardiovascular care. In 1999, the Scientific Forum on Quality of Care and Outcomes Research in Cardiovascular Disease and Stroke was launched. Several years later, the AHA formed the Interdisciplinary Working Group on Quality of Care and Outcomes Research to allow a governing struct...
