From the Guidelines
The patient's echocardiogram shows a normal heart with sinus rhythm, and no treatment is necessary for heart failure with normal left ventricular ejection fraction (LVEF) at this time, as the current evidence does not support the use of specific medications for patients with normal LVEF and no symptoms of heart failure 1.
Patient's Echocardiogram Results
The left ventricle has a normal size (LVIDd 5.3 cm) and normal wall thickness without left ventricular hypertrophy (IVSd 0.6 cm, LVPWd 0.7 cm). Left ventricular systolic function is normal with an ejection fraction of 54% by Simpson's method and 55-60% by visual assessment. The left ventricular mass index is normal at 61 g/m².
Diastolic Function
Diastolic function is normal with an E/A ratio of 1.2, deceleration time of 209 ms, and normal tissue Doppler velocities (E' septal 13.2 cm/s, E' lateral 18.8 cm/s). The E/E' ratios (medial 9.2, lateral 6.5) are within normal range, indicating normal left ventricular filling pressures.
Left Atrium
The left atrium is normal in size with a very small indexed volume of 8.3 ml/m².
Recommendations
According to the ACC/AHA 2005 guideline update for the diagnosis and management of chronic heart failure in the adult, physicians should control systolic and diastolic hypertension, in accordance with published guidelines, which is a Class I recommendation with Level of Evidence A 1. However, in this case, there is no indication of hypertension or any other condition that would require treatment.
Quality of Life and Morbidity
Given the patient's normal echocardiogram results, there is no evidence to suggest that the patient has heart failure with normal LVEF, and therefore, no treatment is necessary at this time 1. The patient's quality of life and morbidity are not expected to be affected by any underlying heart condition, as the echocardiogram results are normal.
Mortality
The patient's mortality risk is not increased, as the echocardiogram results are normal, and there is no evidence of any underlying heart condition that would increase the risk of mortality 1.
From the Research
Left Ventricle Assessment
- The left ventricle chamber size is reported as normal with an LVIDd of 5.3 cm, which is within the normal range according to 2.
- The left ventricular hypertrophy (LVH) is also reported as normal with an IVSd of 0.6 cm and LVPWd of 0.7 cm.
- The systolic function is normal with an EF of 55-60% and a mass index of 61 g/m², which is consistent with the findings of 2.
Diastolic Function Assessment
- The diastolic function is reported as normal with an E/A ratio of 1.2 and a DT of 209 ms, which is in line with the guidance provided by 3.
- The E' septal and lateral values are 13.2 cm/s and 18.8 cm/s, respectively, and the E/E' medial and lateral values are 9.2 and 6.5, respectively.
- These values are consistent with normal diastolic function, as described in 3 and 4.
Left Atrium Assessment
- The left atrium size is reported as normal with a trace indexed volume of 8.3 ml/m².
- The assessment of left atrium size and function is an important aspect of evaluating diastolic function, as highlighted in 3 and 4.
Clinical Implications
- The assessment of left ventricular size and function, as well as diastolic function, is crucial for understanding global cardiac function and identifying the wider effects of disease processes, as emphasized in 3 and 4.
- The use of echocardiography as a primary imaging modality for assessing left ventricular function is supported by the findings of 2, 3, and 4.
