Factors associated with perioperative anxiety among patients undergoing coronary angiography or angioplasty: a cross-sectional study.

Background: Anxiety is commonly encountered in patients undergoing medical procedures or surgeries and contributes to adverse outcomes including physiological damage, prolonged postoperative care, and rehabilitation. This study aimed to identify factors related to anxiety among patients undergoing coronary procedures. Methods: This cross-sectional study was conducted at a tertiary hospital in Vietnam. Patients were included in our study if they were scheduled for coronary angiography or angioplasty. Pre-operative Intrusive Thought Inventory was employed to assess the patient's anxiety level. Result: Three hundred six patients scheduled for coronary procedure met inclusion criteria. High perioperative anxiety was reported by 56.2% of patients undergoing coronary angiography/angioplasty. Multivariable analysis showed that factors independently associated with high perioperative anxiety were no previous coronary angiography/angioplasty (odd ratio [OR]: 2.69 [1.44-5.01]), lack of pre-procedural anesthesia information (OR: 5.12 [2.54-10.31]) and prolonged indication-to-procedure duration (OR: 1.08 [1.05-1.11]). Conclusion: Although coronary angiography or angioplasty were minimally invasive procedures, high perioperative anxiety was significant among patients scheduled for these procedures. Extended waiting time, no procedural experience, and inadequate anesthesia information were associated with increased levels of anxiety.
