Angina is subjective certainly, however the dubious nature of LV wall motion and EF assessment are also suspect with interobserver variability on echo of ~10% which is why ranges are often used. Additionally, data from revived-bcis2 would indicate in low EF patients there’s no definitive data for PCI. I’m not sure a small improvement in …
Angina is subjective certainly, however the dubious nature of LV wall motion and EF assessment are also suspect with interobserver variability on echo of ~10% which is why ranges are often used. Additionally, data from revived-bcis2 would indicate in low EF patients there’s no definitive data for PCI. I’m not sure a small improvement in LV function is enough to warrant routine PCI unless clinical outcomes mirrored the LV function improvement. Hard clinical outcomes would be ideal, CV mortality, etc... I don’t believe orbita2 powered for CV outcomes only angina and QOL.
