Chitosan-Based Hemostatic Pad Reduced Vascular Complications After Transradial Coronary Intervention in Uncontrolled Hypertensive Patients: Application of Chitosan-Based Hemostatic Pad on CAG or PCI

Background: Vascular complications after coronary angiography (CAG) or percutaneous coronary intervention (PCI) are a major concern for revascularization therapies. In this study, we investigated whether the application of a chitosan-based hemostatic pad (HP) could ameliorate vascular complications after CAG or PCI procedures.

Methods: We retrospectively analyzed patients undergoing CAG or PCI in our cardiovascular center from January 2019 to December 2021. The incidence of total vascular complications including errhysis, large hematoma, pseudoaneurysm, radial artery occlusion (RAO), blister, and pain was recorded. Subgroup analyses of patients with a history of hypertension, patients with uncontrolled hypertension, and patients with controlled hypertension were performed.

Results: Our results demonstrated that the application of chitosan-based HP had no effect on vascular complications after CAG or PCI procedures (odds ratio [OR]: 1.03 (0.84–1.26), p = 0.80). Nevertheless, chitosan-based HP treatment markedly decreased the incidence of vascular complications in uncontrolled hypertensive patients (OR: 0.32 (0.11–0.95), p = 0.04), but not in hypertensive patients with controlled blood pressure (BP) (OR: 1.09 (0.88–1.35), p = 0.42).

Conclusions: Chitosan-based HP treatment could reduce the incidence of vascular complications in patients with uncontrolled hypertension. Nonetheless, applying chitosan-based HP treatment after CAG or PCI procedures is not recommendable for controlled hypertensive patients.
