Results
Forty-one consecutive patients (36 males, age 59 ± 10 years) were studied at baseline and after 6 months. According to the 6-month CMR LV-EDV variation, 10 patients (24%) showed LVR and 31 did not (76%). At baseline, LVR patients had a lower LV-EF, LV-GFI, GLS, and a higher MVO and SAS area. No significant differences were observed in terms of LV volumes and MSI although there was a trend for lower LV-EDV and higher LV-ESV mean values for LVR patients. At the univariable analysis, a significant correlation was found between the 6-month LV-EDV variation and baseline SAS area [r = 0.81, P < 0.001];LV-GFI (r = −0.56, P < 0.001), MVO (r = 0.55, P < 0.001), LV-EF (r = −0.42, P = 0.006), and GLS (r = 0.42, P = 0.007), whereas MSI did not show a significant correlation (r = −0.25, P = 0.113). At the multivariable analysis, a significant correlation remained only for the SAS area (r = 0.80, P < 0.001). The ROC curve analysis showed that a baseline SAS area ≥15% predicted LVR at 6 months with a sensitivity and a specificity of 80.0% and 90.3%, respectively [AUC 0.934, 95% CIs 0.810–0.988, P < 0.001].
