2017 ESC Guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation: The Task Force for the management of acute myocardial infarction in patients presenting with ST-segment elevation of the European Society of Cardiology (ESC).

The American College of Cardiology (ACC)/American Heart Association (AHA) Task Force on Practice Guidelines was formed to make recommendations regarding the diagnosis and treatment of patients with known or suspected cardiovascular disease. Coronary artery disease (CAD) is the leading cause of death in the United States. Unstable angina (UA) and the closely related condition non–ST-segment elevation myocardial infarction (NSTEMI) are very common manifestations of this disease. These life-threatening disorders are a major cause of emergency medical care and hospitalizations in the United States. In 1996, the National Center for Health Statistics reported 1 433 000 hospitalizations for UA or NSTEMI. In recognition of the importance of the management of this common entity and of the rapid advances in the management of this condition, the need to revise guidelines published by the Agency for Health Care Policy and Research (AHCPR) and the National Heart, Lung and Blood Institute in 1994 was evident. This Task Force therefore formed the current committee to develop guidelines for the management of UA and NSTEMI. The present guidelines supersede the 1994 guidelines.

The customary ACC/AHA classifications I, II, and III summarize both the evidence and expert opinion and provide final recommendations for both patient evaluation and therapy:

Class I: Conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective .

Class II: Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a procedure or treatment. 

Class IIa: Weight of evidence/opinion is in favor of usefulness/efficacy. 

Class IIb: Usefulness/efficacy is less well established by evidence/opinion. 

Class III: Conditions for which there is evidence and/or general agreement that the procedure/treatment is not useful/effective and in some cases may be harmful. 

The weight of the evidence was ranked highest (A) if the data …

ACC/AHA 2005 Guideline Update for the Diagnosis and Management of Chronic Heart Failure in the Adult

BACKGROUND\nSeveral large-scale trials have demonstrated improved survival with ACE-inhibitor therapy started during acute myocardial infarction. A systematic overview was conducted to resolve uncertainties regarding time of initiation, time course of effect, and identification of patients in whom the benefits or the risks may be greater.\n\n\nMETHODS AND RESULTS\nThis overview aimed to include individual data from all randomized trials involving more than 1000 patients in which ACE-inhibitor treatment was started in the acute phase (0 to 36 hours) of myocardial infarction and continued for a short time (4 to 6 weeks). Data were available for 98,496 patients from 4 eligible trials, and the results were consistent among the trials. Thirty-day mortality was 7.1% among patients allocated to ACE inhibitors and 7.6% among control subjects, corresponding to a 7% (SD, 2%) proportional reduction (95% CI, 2% to 11%; 2P<0.004). This represented avoidance of approximately 5 (SD, 2) deaths per 1000 patients, with most of the benefit observed within the first week. The proportional benefit was similar in patients at different underlying risk. The absolute benefit was particularly large in some high-risk groups (ie, Killip class 2 to 3, heart rate > or = 100 bpm at entry) and in anterior MI. ACE-inhibitor therapy also reduced the incidence of nonfatal cardiac failure (14.6% versus 15.2%, 2P=0.01) but was associated with an excess of persistent hypotension (17.6% versus 9.3%, 2P<0.01) and renal dysfunction (1.3% versus 0.6%, 2P<0.01).\n\n\nCONCLUSIONS\nThese results support the use of ACE inhibitors early in the treatment of acute MI, either to a wide range of patients or selectively in patients with anterior MI and in those at increased risk of death.
