High CHA2DS2-VASc scores in atrial fibrillation (AF) patients are generally associated with increased risks of stroke and dementia. In lower CHA2DS2-VASc scores there remains an unquantifiable cranial injury risk, necessitating an improved risk assessment method within these lower risk groups.  The objective of this article is to determine if sex-specific Intermountain Mortality Risk Scores (IMRS), a dynamic
measurement of systemic health comprised of commonly performed blood tests, can stratify dementia risk overall, and among CHA2DS2-VASc strata in AF patients.

Learning Objectives

Upon completion of this activity, participants will be able to:

1.  Understand the use of C-statistics as applied to model-based estimated of risk
2.  Recognize the meaning of C-statistics for the CHADS2 and CHA2DS2 Vasc scoring systems used commonly in clinical practice as a means to ascertain risk of thromboembolism in patients with atrial fibrillation
3.  Understand the components and use of the Intermountain Mortality Risk Scores (IMRS) to identify atrial fibrillation patients at risk of dementia independent of traditional risk scoring systems
4.  Recognize the value of biomarkers as they relate to systemic measurements of health in patients with atrial fibrillation

It is the policy of the Heart Rhythm Society to ensure balance, independent objectivity, and scientific rigor in all its certified educational activities. Everyone involved in the planning and participation of continuing medical education activities is required to disclose any real or apparent conflicts of interest related to the content in his/her presentation(s) and also disclose discussions of unlabeled/unapproved uses of drugs or devices during his/her presentation(s).

Content Development
All Heart Rhythm Society content--from objectives to content development, evaluation and measuring outcomes--is developed in compliance with ACCME guidelines. The Society’s education content is developed by expert physicians and vetted through the Education Committee to ensure alignment with organization strategic goals and that content is appropriate. Content is then reviewed by the CME Subcommittee to ensure quality and balance. HRS deploys a standard content validation form that must be signed by reviewers that states the content has been reviewed and approved.

Heart Rhythm Society takes steps to assure its learners and the public that the content of certified activities is accurate and reliable. The following principles are applied to the process of validating CME content. The content is peer-reviewed to ensure the following:

  • Fair Balance - that content is balanced among various options available for treatment and not biased toward a particular product or manufacturer.
  • Patient Treatment Recommendations - that patient treatment recommendations contained in the content are evidence-based, are appropriate for the target audience, and that the patient treatment recommendations contribute to overall improvement in patient care.
  • Scientific Validity - that scientific studies cited in the activity conform to standards accepted by the scientific community.
  • Learning Objectives - that the educational content supports the learning objectives of the activity, and that the objectives stated for performance-in-practice are actionable and measurable.
  • Omission and Commission - are there any studies, data, or best evidence that is missing?

CME Mission Statement
The Heart Rhythm Society CME Mission provides a framework for guiding and conducting the organization’s CME program and its educational activities. The CME Mission is clearly aligned with the Organizational Mission. The CME Mission Statement consists of six essential elements: purpose, scope, target audience, content, types of activities, and expected results. The purpose and scope of the Heart Rhythm Society CME Mission is to provide academically rigorous learning through the use of innovative teaching methods and advanced technologies that will enhance the ability of heart rhythm specialists worldwide to provide excellent patient care throughout their careers. The target audience is primarily heart rhythm physician specialists, but also includes scientists and other healthcare professionals who are dedicated to the study and management of heart rhythm disorders. The content covers any topic that addresses disturbances of the heart's rhythm or electrical activation, including the diagnosis, treatment, and prevention of bradyarrhythmias, tachyarrhythmias, sudden death, and cardiac dysfunction associated with electrophysiologic abnormalities. Emphasis will be placed on education designed to improve quality of life and survival for patients.

To accomplish the CME Mission, the Heart Rhythm Society currently develops the following types of educational activities:

  • Educational courses and symposia, including didactic presentations, interactive computer sessions and workshops;
  • Enduring materials, including audiotapes, CD-ROMs, and Webcasts;
  • Activities, such as those listed above, developed through collaboration with other medical organizations, in compliance with the ACCME Essentials and Standards

Expected results include improved knowledge and understanding resulting in improvements in health care provider competence, performance, or patient outcomes. Whenever possible, educational activities will be designed to address gaps in performance as compared to accepted performance measures or benchmarks determined by expert consensus and based upon scientific evidence. Evaluation of changes in behavior as a result of educational interventions will help guide future initiatives.
