Normal Left Ventricular Ejection Fraction for a 65-Year-Old Male
For a 65-year-old male, normal left ventricular ejection fraction (LVEF) ranges from 53-73% by echocardiography, with values below 53% considered abnormal. 1
Echocardiography-Based Reference Values
The most authoritative guideline data comes from the 2015 ASE/EACVI recommendations, which established that:
- Normal LVEF: 63 ± 5% (mean ± standard deviation)
- Normal range: 53-73% using the biplane method of disks
- Key finding: EF is NOT significantly related to age, gender, or body surface area 1
This means your 65-year-old male patient should be evaluated using the same reference range as younger adults, as age does not meaningfully affect normal LVEF values by echocardiography.
Cardiac MRI Reference Values (If Applicable)
If cardiac MRI is used instead, the 2019 European guidelines provide slightly different thresholds 2:
- Normal LVEF for men: 57-77%
- Mildly abnormal: 41-56%
- Moderately abnormal: 30-40%
- Severely abnormal: <30%
Important caveat: CMR and echocardiography values should never be directly compared due to different measurement techniques, spatial resolution, and inclusion of different anatomical structures 2.
Recent Meta-Analysis Findings
A 2026 meta-analysis of population-based studies (n=10,427) provides additional context 3:
- Pooled mean LVEF: 61.9% for men
- Lower limit of normal: 51.7% for men
- Critical threshold: LVEF <50% has <5% probability of being normal across all demographic groups
This reinforces that an LVEF below 50% is highly unlikely to represent normal cardiac function, regardless of age.
Clinical Application Algorithm
For your 65-year-old male patient:
- If LVEF ≥53% → Consider normal (by echo guidelines)
- If LVEF 50-52% → Borderline; consider repeat measurement, assess for technical factors, and evaluate clinical context
- If LVEF <50% → Abnormal; warrants further cardiac evaluation regardless of symptoms
Important Technical Considerations
Measurement variability matters: The biplane method of disks (modified Simpson's rule) is the recommended technique 1. Single-plane or M-mode calculations may be less accurate, particularly in elderly patients where contraction patterns shift from longitudinal to circumferential shortening 4.
Avoid the "supranormal" trap: While LVEF >70% might seem reassuring, recent evidence suggests LVEF 70-80% and ≥80% are associated with increased adverse outcomes and may reflect underlying pathology rather than superior cardiac function 5. The optimal LVEF range appears to be 60-70%.
Key Pitfalls to Avoid
- Don't assume age-related decline: Unlike many physiological parameters, normal LVEF does not decrease with age by echocardiography 1
- Don't use different modality cutoffs interchangeably: Echo and CMR have different normal ranges 2
- Don't rely solely on LVEF: It reflects global ejection performance, not direct myocardial contractility, and can be normal despite impaired longitudinal function 6
