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.
