Management of Patients With ST-Elevation Myocardial Infarction
Guidelines for the Management of Patients With Unstable Angina/Non–ST-Elevation MI
Preventing Heart Attack and Death in Patients with Atherosclerotic CV Disease
Management of Patients with Chronic Stable Angina
Update for Coronary Artery Bypass Graft Surgery
Evaluation and Management of Chronic Heart Failure in the Adult
Primary Prevention of CV Disease in People with Diabetes Mellitus
Standards of Medical Care in Diabetes

IntroductionIntroduction
• Evidence based guidelines are based on rigorous expert analysis of available data, documenting relative benefits and risks of procedures and therapies.
• ACC/ADA/AHA practice guidelines reflect a consensus of expert opinion and are intended to assist healthcare providers in decision making by describing a range of approaches for the diagnosis, management, and prevention of CVD.
• The guidelines are intended to help improve the effectiveness of care, optimize patient outcomes, and favorably affect the overall cost of care by focusing resources on the most effective strategies.

Classification of Classification of Recommendations and Levels Recommendations and Levels of Evidenceof Evidence
*Data available from clinical trials or registries about the usefulness/efficacy in different subpopulations, such as gender, age, history of diabetes, history of prior myocardial infarction, history of heart failure, and prior aspirin use. A recommendation with Level of Evidence B or C does not imply that the recommendation is weak. Many important clinical questions addressed in the guidelines do not lend themselves to clinical trials. Even though randomized trials are not available, there may be a very clear clinical consensus that a particular test or therapy is useful or effective.
†In 2003, the ACC/AHA Task Force on Practice Guidelines developed a list of suggested phrases to use when writing recommendations. All guideline recommendations have been written in full sentences that express a complete thought, such that a recommendation, even if separated and presented apart from the rest of the document (including headings above sets of recommendations), would still convey the full intent of the recommendation. It is hoped that this will increase readers’ comprehension of the guidelines and will allow queries at the individual recommendation level.

CHD=Coronary heart disease
Primordial Prevention: Prevention of coronary heart disease risk factors
Primary Prevention: Modification of risk factors in order to prevent or delay the onset of coronary heart disease
Secondary Prevention: Initiation of therapy to reduce recurrent coronary heart disease events and decrease cardiac mortality in patients with established coronary heart disease
