Abstract

More than 2 million Americans have heart failure, and about 400,000 new cases are diagnosed each year. Mortality is high, with 5-year mortality in the range of 50 percent. Many of the almost 1 million hospitalizations each year for heart failure might be prevented by improved evaluation and care.

This Quick Reference Guide for Clinicians summarizes major recommendations in Heart Failure: Evaluation and Care of Patients with Left-Ventricular Systolic Dysfunction. Clinical Practice Guideline No. 11. The document was prepared by RAND, a nonprofit research and policy organization, and a private-sector panel of experts and consumers. Guideline recommendations are intended for use by a broad range of health care practitioners.

The guideline recommendations are based on a combination of evidence obtained through extensive literature reviews and on expert judgment where evidence was lacking. Specific recommendations are made in the following areas:

  • Prevention of heart failure with asymptomatic left-ventricular systolic dysfunction.
  • Approaches to diagnosis and initial evaluation of suspected heart failure.
  • Hospital admission and discharge criteria.
  • Pharmacological management.
  • Patient counseling and education.
  • Exercise and rehabilitation.
  • Evaluation for myocardial revascularization.
  • Patient monitoring and followup evaluation.

Table 1. Recommended Tests for Patients With Signs or Symptoms of Heart Failure

Test Recommendation Finding Suspected Diagnosis
Electrocardiogram Acute ST-T wave changes Atrial fibrillation, other tachyarrhythmia Myocardial ischemia Thyroid disease or heart failure due to rapid ventricular rate
  Bradyarrhythmias Heart failure due to low heart rate
  Previous MI (e.g., Q waves) Heart failure due to reduced left-ventricular performance
  Low voltage Pericardial effusion
  Left-ventricular hypertrophy Diastolic dysfunction
Complete blood count Anemia Heart failure due to or aggravated by decreased oxygen-carrying capacity
Urinalysis Proteinuria Nephrotic syndrome
  Red blood cells or cellular casts Glomerulonephritis
Serum creatinine Elevated Volume overload due to renal failure
Serum albumin Decreased Increased extravascular volume due to hypoalbuminemia
T4 and TSH (obtain only if atrial fibrillation, evidence of thyroid disease, or patient age >65) Abnormal T4 or TSH Heart failure due to or aggravated by hypo/hyperthyroidism

Note: TSH = Thyroid-stimulating hormone, MI = myocardial infraction.

Table 2. Echocardiography and Radionuclide Ventriculography Compared in Evaluation of Left-Ventricular Performance

Test Advantages Disadvantages
Echocardiogram Permits concomitant assessment of valvular disease, left-ventricular hypertrophy, and left-atrial size Less expensive than radionuclide ventriculography in most areas Able to detect pericardial effusion and ventricular thrombus More generally available Difficult to perform in patients with lung disease Usually only semi-quantitative estimate of ejection fraction provided Technically inadequate in up to 18% of patients under optimal circumstances
Radionuclide ventriculogram More precise and reliable measurement of EF Better assessment of right-ventricular function Requires venipuncture and radiation exposure Limited assessment of valvular heart disease and left-ventricular hypertrophy

Table 3. Suggested Topics for Patient, Family, and Caregiver Education and Counseling

General Counseling
  • Explanation of heart failure and the reason for symptoms
  • Cause or probable cause of heart failure
  • Expected symptoms
  • Symptoms of worsening heart failure
  • What to do if symptoms worsen
  • Self-monitoring with daily weights
  • Explanation of treatment/care plan
  • Clarification of patient's responsibilities
  • Importance of cessation of tobacco use
  • Role of family members or other caregivers in the treatment/care plan
  • Availability and value of qualified local support group
  • Importance of obtaining vaccinations against influenza and pneumococcal disease
Prognosis
  • Life expectancy
  • Advance directives
  • Advice for family members in the event of sudden death
Activity Recommendations
  • Recreation, leisure, and work activity
  • Exercise
  • Sex, sexual difficulties, and coping strategies
Dietary Recommendations
  • Sodium restriction
  • Avoidance of excessive fluid intake
  • Fluid restriction (if required)
  • Alcohol restriction
Medications
  • Effects of medications on quality of life and survival
  • Dosing
  • Likely side effects and what to do if they occur
  • Coping mechanisms for complicated medical regimens
  • Availability of lower cost medications or financial assistance
Importance of Compliance With the Treatment/Care Plan
