Heart Failure with Preserved LVEF,HFSA 2010 Recommendations,HFSA 2010 Practice Guideline Preserved LVEFDiagnosis,Recommendation 11.1 Careful attention to differential diagnosis is recommended in patients with HF and preserved LVEF to distinguish among a variety of cardiac disorders, because treatments may differ. These various entities may be distinguished based on: Echocardiography Electrocardiography Stress imaging (via exercise or pharmacologic means, using myocardial perfusion or echocardiographic imaging). Cardiac catheterization,Strength of Evidence = C,Figure 11.1. Diagnostic Criteria: HF with Reduced vs. HF with Preserved EF,Clinical evidence of HF: Clear clinical presentation of HF or Framingham or Boston criteria If uncertain: Plasma BNP or chest x-ray or cardiopulmonary exercise testing,LVEF 50%,LVEF 50%,Supportive evidence: Eccentric LVH or remodeling,Supportive evidence: Concentric LVH or remodeling Left atrial enlargement in absence of AF Echo Doppler or catheter evidence of diastolic dysfunction,Exclusions: Non-myocardial disease,Exclusions: Non-myocardial disease,Adapted from Yturralde FR. Prog Cardiovasc Dis 2005;47:314-19,HF with Reduced EF,Non-Myocardiala,High output Anemia, AV fistula,Valvular disease AS, AR, MR, MS,Myocardialb,Hypertension,CAD,Diabetes,Infiltrative myopathyc,Cardiomyopathy genetic, post-partum, viral, drug/radiation,HF with Preserved EF,Non-Myocardiala,High output Anemia, AV fistula,Valvular disease AS, AR, MR, MS,Myocardialb,Hypertension,CAD,Diabetes,Cardiomyopathy genetic, post-partum, viral, drug/radiation,Infiltrative myopathyc,Pericardial constraint constriction, tamponade,Figure 11.2. Etiology of HF with Reduced vs. HF with Preserved LVEF,a = cause of HF or specific target for therapy b = disease process that may lead to HF c = may have stage in which EF is normal, but often declines,Figure 11.3. Diagnostic Algorithm for HF with Preserved LVEF,No inducible ischemia, fibrotic, collagen- Vascular, RCM, cardinoid, diabetes, Radiation or chemotherapy induced heart disease, infiltrative disease, co- morbid conditions, reconsider diagnosis of HF,HFSA 2010 Practice Guideline Preserved LVEFEvaluation,Recommendation 11.2 Evaluation for ischemic heart disease and inducible myocardial ischemia is recommended in patients with HF and preserved LVEF. Strength of Evidence = C,HFSA 2010 Practice Guideline Preserved LVEFBlood Pressure,Recommendation 11.3 Blood pressure monitoring is recommended in patients with HF and preserved LVEF. Strength of Evidence = C,HFSA 2010 Practice Guideline Preserved LVEFLow Sodium Diet,Recommendation 11.4 Counseling on the use of a low sodium diet is recommended for all patients with HF, including those with preserved LVEF. Strength of Evidence = C,HFSA 2010 Practice Guideline Preserved LVEFDiuretics,Recommendation 11.5 Diuretic treatment is recommended in all patients with HF and volume overload, including those with preserved LVEF. Treatment may begin with either a thiazide or loop diuretic. In more severe volume overload or if response to a thiazide is inadequate, treatment with a loop diuretic should be implemented. Avoid excessive diuresis, which may lead to orthostatic changes in blood pressure and worsening renal function.,Strength of Evidence = C,HFSA 2010 Practice Guideline Preserved LVEFARBs or ACEIs,Recommendation 11.6 In the absence of other indications for these drugs, ARBs or ACE inhibitors may be considered in patients with HF and preserved LVEF: ARBs Strength of Evidence = C ACE inhibitors Strength of Evidence = C,HFSA 2010 Practice Guideline Preserved LVEFACE Inhibitors,Recommendation 11.7 ACE inhibitors should be considered in all patients with HF and preserved LVEF who have: symptomatic atherosclerotic cardiovascular disease or diabetes and one additional risk factor Strength of Evidence = C In patients who meet these criteria but are intolerant to ACE inhibitors, ARBs should be considered. Strength of Evidence = C,HFSA 2010 Practice Guideline Preserved LVEFBeta Blockers,Recommendation 11.8 Beta blocker treatment is recommended in patients with HF and preserved LVEF who have: Prior MI Strength of Evidence = A Hypertension Strength of Evidence = B Atrial fibrillation requiring control of ventricular rate Strength of Evidence = B,HFSA 2010 Practice Guideline Preserved LVEFCCBs,Recommendation 11.9 Calcium channel blockers should be considered in patients with HF and preserved LVEF and: Atrial fibrillation requiring control of ventricular rate and intolerance to beta blockers. In these patients, diltiazem or verapamil should be considered. Strength of Evidence = C Symptom-limiting angina. Strength of Evidence = A Hypertension.
