Heart Failure

Diagnosis
  • Use echocardiography to screen for valvular heart disease in patients with significant murmurs. Do not use echocardiography to screen for heart failure in asymptomatic patents without murmurs.

  • Obtain an electrocardiogram and chest x-ray in patients with suspicion for heart failure to aid in diagnosis and provide insight into the cause of ventricular dysfunction.

  • Perform echocardiography and use results to define the type and extent of ventricular dysfunction and to identify potentially reversible causes of heart failure.

  • Use exercise testing to confirm functional capacity in heart failure, to look for ischemia, and to differentiate it from other conditions

  • Order laboratory studies to aid in diagnosis or to identify secondary causes of heart failure, including electrolytes, blood counts, and thyroid studies.

Therapy
  • Advise patients with heart failure to limit salt to 2 g sodium and fluid intake to 2 quarts daily.

  • Use ACE inhibitors in all patients with heart failure regardless of functional class except in patients with a history of angioedema; use ARBs instead in patients intolerant of ACE inhibitors.

  • Use β-blockers in patients with all NYHA classes of heart failure.

  • Use hydralazine combined with nitrates as an alternative to ACE inhibitors or ARBs in patients intolerant to both, and consider adding it to standard therapy in African-American patients with heart failure.

  • Use low doses of an aldosterone antagonist in patients with NYHA class III to IV heart failure on ACE inhibitors and β-blockers.

  • Use loop diuretics to control volume overload and improve the functional capacity of patients with heart failure.

  • Evaluate patients with heart failure and ventricular arrhythmias, syncope, sudden cardiac death, or EF < 35% for ICD placement.

  • Consider cardiac resynchronization therapy for patients with NYHA class III or IV heart failure, EF <35% and prolonged QRS duration.

  • Treat patients with a normal ejection fraction and signs and symptoms of heart failure for diastolic dysfunction.
