The prevalence of diabetes mellitus (DM) in patients requiring cardiac
surgery is significantly increasing, and achieving tight perioperative
glycemic control in DM patients may decrease perioperative morbidity and
improve survival [7] . Current studies have demonstrated a
negative correlation between DM and the occurrence of aortic diseases[8-11] . However, previous studies are contradictory in that
patients with DM were found to have poorer outcomes after abdominal
aortic aneurysm repair [12], whereas mortality and clinical
complications in type B aortic dissection patients after TEVAR were
significantly reduced in DM patients [13] . In our previous
study, we demonstrated that uncomplicated type A IMH patients with DM
(receiving the “wait‐and‐watch strategy” and tight glycemic control)
may have lower aorta‐related mortality and rates of aorta‐related
adverse events and reintervention than patients in the non-DM group[14] .
Whether patients with uncomplicated IMHB (receiving the “wait‐and‐watch
strategy”) may benefit from tight glycemic control remains unclear.
Thus, we hypothesized that among uncomplicated IMHB patients receiving
the “wait-and-watch strategy” (combined with tight glucose
management), patients with DM (compared with patients without DM) would
benefit from such a treatment strategy. In this study, we aimed to
summarize the clinical presentations, therapeutic approaches, and
outcomes of IMHB patients with and without DM.
