Please explain in simple terms the echo results showing moderate concentric left‑ventricular hypertrophy, left‑ventricular ejection fraction 55‑60 %, mild ascending aortic dilation (3.9 cm), severe pulmonary artery dilation (5.4 cm), and the recommendation for NYHA heart‑failure staging.

Understanding Your Echocardiogram Results

Your echo shows a thickened heart muscle (likely from high blood pressure), normal pumping strength, but a severely enlarged lung artery that requires urgent evaluation for pulmonary hypertension and formal heart failure classification.

What Each Finding Means

1. Moderate Concentric Left Ventricular Hypertrophy

• Your heart's main pumping chamber has thickened walls all around, most commonly caused by chronic high blood pressure 1.
• This thickening increases your risk of heart failure, abnormal heart rhythms, and cardiovascular death, even when blood pressure is controlled 1.
• This is not simply an "adaptive" response—it represents pathologic remodeling that predicts worse outcomes and requires aggressive treatment 2.
• Approximately 13% of patients with this pattern progress to weakened heart function over 3 years, especially if you've had a heart attack, have a wide QRS on ECG, or have persistently elevated blood pressure 3.

2. Left Ventricular Ejection Fraction 55-60%

• Your heart's pumping strength is normal (normal range is 55-70%) 1.
• However, normal pumping function does not exclude heart failure—up to one-third of patients with cardiac shortness of breath have abnormal relaxation (diastolic dysfunction) despite normal ejection fraction 1, 4.
• The combination of thickened walls and normal ejection fraction suggests you may have early-stage heart disease that could progress 3.

3. Mild Ascending Aorta Dilatation (3.9 cm)

• Your aorta (the main artery leaving your heart) is mildly enlarged 1.
• Normal ascending aorta diameter is typically <3.7 cm, so 3.9 cm represents mild dilation that warrants monitoring 1.
• This finding requires periodic follow-up imaging to ensure it doesn't progress, though it's not immediately dangerous at this size 1.

4. Severely Dilated Pulmonary Artery (5.4 cm)

• This is the most concerning finding on your echo 1.
• Normal pulmonary artery diameter is <2.5 cm, so 5.4 cm represents severe, marked enlargement 1.
• This strongly suggests pulmonary hypertension (high blood pressure in the lung arteries), which requires immediate investigation 1.
• Pulmonary hypertension can result from left heart disease (related to your thickened heart muscle), primary lung disease, blood clots in the lungs, or other causes 1.

Why NYHA Heart Failure Staging Is Recommended

The combination of left ventricular hypertrophy, potential diastolic dysfunction, and severe pulmonary artery dilation indicates you likely have heart failure or are at high risk for developing it 1.

NYHA (New York Heart Association) classification assesses your symptoms:

• Class I: No symptoms with ordinary activity
• Class II: Slight limitation—comfortable at rest, but ordinary activity causes fatigue or shortness of breath
• Class III: Marked limitation—comfortable at rest, but less-than-ordinary activity causes symptoms
• Class IV: Symptoms at rest

This staging helps guide treatment intensity and prognosis 1.

What You Need Next

Immediate Workup for Pulmonary Hypertension

• Right heart catheterization to measure pulmonary artery pressures directly 1.
• Evaluation for blood clots in the lungs (CT pulmonary angiography or ventilation-perfusion scan) 1.
• Pulmonary function tests and assessment for chronic lung disease 1.
• Assessment of left ventricular filling pressures (diastolic function) to determine if pulmonary hypertension is due to left heart disease 1.

Blood Pressure Control

• Aggressive blood pressure management is essential to prevent progression of left ventricular hypertrophy and reduce cardiovascular risk 1.
• ACE inhibitors, beta-blockers, or certain calcium channel blockers can reduce left ventricular mass, whereas diuretics alone may not 5.

Cardiac MRI Consideration

• If there's any concern for infiltrative disease (amyloidosis, sarcoidosis) or if echocardiography doesn't fully explain your findings, cardiac MRI provides superior tissue characterization 1, 6, 7.

Key Pitfalls to Avoid

• Do not assume your heart is fine because ejection fraction is normal—diastolic dysfunction can cause severe symptoms and requires specific evaluation 1, 4.
• Do not delay investigation of the severely dilated pulmonary artery—this finding demands urgent workup for pulmonary hypertension, which significantly impacts treatment and prognosis 1.
• Do not rely on blood pressure readings alone to assess adequacy of treatment—serial echocardiography to monitor left ventricular mass regression is necessary 1.
