Results
109 IMHA patients were included in this study, and 66 patients were
included after matching. Patients without DM experienced significantly
more aorta-related adverse events (51.6% vs 13.3%, P=0.001) and
reinterventions than patients in the DM group (29.0% vs 6.7%,
P=0.023). Cox regression analysis revealed that a higher matrix
metalloproteinase-9 level (hazard ratio [HR], 1.70; 95% confidence
interval [CI], 1.39-2.09, P <0.001) and larger
maximum aortic diameter (HR, 1.41; 95% CI, 1.11-1.80, P =0.005)
were associated with higher aorta-related mortality. The competing risk
analysis revealed a significantly higher aorta-related mortality during
the follow-up period in the no DM group than in the DM group (36.4%;
95% CI, 11.6%-82.3%, P =0.0294).
