What is the recommended management for a patient with normal left ventricular ejection fraction (LVEF) and no significant valvular abnormalities?

Management of a Patient with Normal Left Ventricular Ejection Fraction and No Significant Valvular Abnormalities

For patients with normal left ventricular ejection fraction (60-65%) and no significant valvular abnormalities, routine clinical follow-up with periodic examinations is recommended, with echocardiographic evaluation every 3-5 years if the patient remains asymptomatic. 1

Assessment and Monitoring

• Patients with normal left ventricular size and function (LVEF 60-65%) without valvular abnormalities generally have a good prognosis and do not require specific cardiac interventions 1
• For asymptomatic patients with normal cardiac function, clinical follow-up should be performed yearly or sooner if new cardiac symptoms develop 1
• Echocardiographic follow-up should be performed every 3-5 years in patients with normal cardiac function and no valvular disease 1
• The normal LVEF range is considered to be ≥50%, with the patient's current LVEF of 60-65% falling well within normal limits 1

Specific Considerations

• Normal right ventricular size and function, as noted in this patient, is also reassuring and does not require specific intervention 1
• Normal atrial sizes (both left and right) indicate absence of chronic pressure or volume overload, which is a favorable prognostic sign 1
• The biplane Simpson's method used to calculate LVEF (60-65%) is considered a reliable technique for assessing left ventricular function 2

Potential Pitfalls and Caveats

• LVEF, while normal in this case, has inherent limitations as it is affected by loading conditions and cavity geometry, and may not always reflect subtle myocardial dysfunction 3
• A normal LVEF does not exclude the possibility of diastolic dysfunction, which can cause heart failure symptoms despite preserved ejection fraction 1
• If the patient develops symptoms such as dyspnea, chest pain, or decreased exercise tolerance despite normal LVEF, further evaluation should be performed to assess for potential diastolic dysfunction or other cardiac conditions 1, 4

Special Circumstances

• If the patient has other cardiac risk factors (hypertension, diabetes, coronary artery disease), more frequent clinical follow-up may be warranted despite normal cardiac structure and function 5
• In patients with normal LVEF but symptoms suggestive of heart failure, evaluation for heart failure with preserved ejection fraction (HFpEF) should be considered 1, 4
• If the patient is an athlete or has a history of athletic training, sinus bradycardia with heart rates as low as 40-45 bpm may be physiologic and not require intervention 6

Follow-up Recommendations

• Instruct the patient to report any new cardiac symptoms promptly, particularly changes in exercise tolerance, shortness of breath, chest discomfort, or palpitations 1
• If new symptoms develop, a repeat comprehensive echocardiogram should be performed to reassess cardiac structure and function 1
• Routine health maintenance and cardiovascular risk factor modification should be emphasized, including blood pressure control, healthy diet, regular exercise, and smoking cessation 5
