Class I Guidelines
1. Measures listed as Class I recommendations for patients in stages A and B are also appropriate for patients in Stage C. (Levels of Evidence: A, B, and C as appropriate)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 1 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 2. Diuretics and salt restriction are indicated in patients with current or prior symptoms of HF and reduced LVEF who have evidence of fluid retention. (Level of Evidence: C)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 2 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 3. Angiotensin converting enzyme inhibitors are recommended for all patients with current or prior symptoms of HF and reduced LVEF, unless contraindicated. (Level of Evidence: A)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 3 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 4. Beta-blockers (using 1 of the 3 proven to reduce mortality, i.e., bisoprolol, carvedilol, and sustained release metoprolol succinate) are recommended for all stable patients with current or prior symptoms of HF and reduced LVEF, unless contraindicated. (Level of Evidence: A)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 4 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 5. Angiotensin II receptor blockers approved for the treatment of HF are recommended in patients with current or prior symptoms of HF and reduced LVEF who are ACEI-intolerant (as in patients with angioedema). (Level of Evidence: A)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 5 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 6. Drugs known to adversely affect the clinical status of patients with current or prior symptoms of HF and reduced LVEF should be avoided or withdrawn whenever possible (e.g., non steroidal anti-inflammatory drugs, most antiarrhythmic drugs, and most calcium channel blocking drugs; see text). (Level of Evidence: B)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 6 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 7. Exercise training is beneficial as an adjunctive approach to improve clinical status in ambulatory patients with current or prior symptoms of HF and reduced LVEF. (Level of Evidence: B)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 7 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 8. An implantable cardioverter-defibrillator is recommended as secondary prevention to prolong survival in patients with current or prior symptoms of HF and reduced LVEF who have a history of cardiac arrest, ventricular fibrillation, or hemodynamically destabilizing ventricular tachycardia. (Level of Evidence: A)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 8 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 9. Implantable cardioverter-defibrillator therapy is recommended for primary prevention to reduce total mortality by a reduction in sudden cardiac death in patients with ischemic heart disease who are at least 40 days post-MI, have an LVEF less than or equal to 30%, with NYHA functional class II or III symptoms while undergoing chronic optimal medical therapy, and have reasonable expectation of survival with a good functional status for more than 1 year. (Level of Evidence: A)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 9 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 10. Implantable cardioverter-defibrillator therapy is recommended for primary prevention to reduce total mortality by a reduction in sudden cardiac death in patients with non ischemic cardiomyopathy who have an LVEF less than or equal to 30%, with NYHA functional class II or III symptoms while undergoing chronic optimal medical therapy, and who have reasonable expectation of survival with a good functional status for more than 1 year. (Level of Evidence: B)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 10 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 11. Patients with LVEF less than or equal to 35%, sinus rhythm, and NYHA functional class III or ambulatory class IV symptoms despite recommended, optimal medical therapy and who have cardiac dyssynchrony, which is currently defined as a QRS duration greater than 0.12 ms, should receive cardiac resynchronization therapy unless contraindicated. (Level of Evidence: A)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 11 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III 12. Addition of an aldosterone antagonist is reasonable in selected patients with moderately severe to severe symptoms of HF and reduced LVEF who can be carefully monitored for preserved renal function and normal potassium concentration. Creatinine should be less than or equal to 2.5 mg/dL in men or less than or equal to 2.0 mg/dL in women and potassium should be less than 5.0 mEq/L. Under circumstances where monitoring for hyperkalemia or renal dysfunction is not anticipated to be feasible, the risks may outweigh the benefits of aldosterone antagonists. (Level of Evidence: B)

 ACC / AHA Guidelines for Diagnosis and Management of Chronic Heart Failure: Class I Recommendation 12 for patients with reduced LVEF should be: CLASS I CLASS IIa CLASS IIb CLASS III
