Why the study?

To assess left ventricular strain in patients with ventricular aneurysm after myocardial infarction using CMR-FT and evaluate its value for long-term prognosis.

Does myocardial strain assessed by CMR-FT predict NYHA classification in patients with ventricular aneurysm after myocardial infarction?

Comparison

NYHA class I (n=25) vs NYHA class II-IV (n=40)

Follow-up

3-12 months

Discussion

Implication

Strain metrics may aid NYHA risk stratification after MI with aneurysm; leaves open prospective validation before clinical adoption.

Structured PICO

Does myocardial strain assessed by CMR-FT predict NYHA classification in patients with ventricular aneurysm after myocardial infarction?

Population

65 patients with ventricular aneurysm (VA) after myocardial infarction (MI) confirmed by coronary angiography, ECG, and echocardiography. Mean age 61.8±11.2 years, 52 men and 13 women. Divided into NYHA I (n=25) and NYHA II-IV (n=40).

Intervention

Cardiac magnetic resonance-feature tracking (CMR-FT) for left ventricular myocardial strain analysis (GLS, GCS, GRS)

Outcome

New York Heart Association (NYHA) classification (NYHA I vs NYHA II-IV) at 1-year follow-upsurrogate

Myocardial strain assessed by CMR-FT is an independent predictor of NYHA class in patients with ventricular aneurysm after myocardial infarction, providing a potential tool for risk stratification.

Limitations

small sample size
short follow-up of 3-6 months after AMI which may neglect long-term prognosis
