Risk factors for acute pulmonary embolism in patients with off-pump coronary artery bypass grafting: implications for nursing

Abstract

Objective Acute pulmonary embolism (APE) is a serious complication after off-pump coronary artery bypass grafting (OPCABG). We aimed to analyze the risk factors for APE in patients with OPCABG. Methods In this retrospective, observational study, patients with OPCABG who were treated in our hospital from 1 January 2018 to 31 March 2020 were included. The basic characteristics of patients and results of preoperative laboratory examinations were collected and analyzed. Results A total of 707 patients with OPCABG were included and the incidence of APE was 3.21%. Left ventricular ejection fraction (LVEF), a history of smoking, number of bypass grafting, duration of surgery, and age were significant risk factors for APE in patients with OPCABG. The areas under the curves of LVEF, number of bypass grafting, duration of surgery, and age were 0.773, 0.759, 0.738, and 0.723, respectively. The cutoff values of LVEF, number of bypass grafting, duration of surgery, and age were 59.84, 3.18, 237.42, and 73.28, respectively. Conclusions LVEF, a history of smoking, number of bypass grafting, duration of surgery, and age may be risk factors for APE in patients with OPCABG. Early measures should be taken to target these risks to prevent APE.

Factors Associated with Acute Pulmonary Embolism in Patients with Hypoxia After off-Pump Coronary Artery Bypass Grafting: A Case-Control Study

“…Prior research has identified various risk factors for PE following OPCABG, with a primary focus on a patient’s medical history and the circumstances before or during surgery. Zhou et al 14 found that factors such as ejection fraction, smoking history, number of grafts, surgery duration, and age were associated with an increased risk of acute PE after OPCABG. Du et al 15 reported that a history of bleeding disorders, congestive heart failure in the 30 days leading up to surgery, and surgery lasting over 310 minutes were linked to a higher likelihood of venous thromboembolism after CABG.…”
