VII. Strain
 

- Medidas de strain-rate en 10 sujetos sanos y en 12 pacientes después de sufrir un infarto agudo de miocardio26

1 12 pacientes con IAM. Se analizan 114 segmentos con contractilidad normal y 76 con alteraciones segmentarias. Edad media 62± 12.
2 10 voluntarios en el grupo control con edades entre 30 ± 7 años. Se analizan 171 segmentos. No diferencias significativas en los valores entre los distintos segmentos.
