A Retrospective Pilot Comparison Trial Investigating Clinical Outcomes in Cardiac Surgical Patients Who Received Sugammadex Reversal During 2018 to 2021.

OBJECTIVES: To compare the number of eligible urgent and elective cardiac surgical patients who could be extubated successfully within 6 hours of surgery and who received sugammadex versus those who did not. DESIGN: This retrospective pilot study compared outcomes in cardiac surgical patients undergoing cardiopulmonary bypass between 2018 to 2021 who received sugammadex versus those who did not. SETTING: At a tertiary-care hospital in the Northshore of Chicago. PARTICIPANTS: A total of 358 elective or urgent cardiac surgical patients who underwent cardiopulmonary bypass (by 1 cardiac surgeon) and were extubated within 24 hours of the end of surgery at Evanston Hospital in Evanston, IL, were included. INTERVENTIONS: Data were examined in the following 2 groups of patients: those who were administered sugammadex and those who were not. MEASUREMENTS AND MAIN RESULTS: After performing propensity matching for age, sex, body mass index, kidney or liver disease, the number of preoperative conditions (defined as the sum of the presence of the following medical conditions: diabetes, immunosuppressive disease, on home oxygen, on inhaled bronchodilator, or sleep apnea), number of patients who underwent elective or urgent surgery in each group, surgery time, cardiopulmonary bypass duration, number of intraoperative blood products, use of intraoperative midazolam and propofol, a statistically significant increase in the percentage of patients in the sugammadex group were extubated within 6 hours of the end of surgery versus those who did not receive sugammadex (96.67% v 81.33%, p = 0.0428). In addition, there was a statistically significant reduction in time to extubation (hours) (4.72 ± 2.92) v (3.57± 1.96 p = 0.0098) in the sugammadex group. All other outcomes did not meet statistical significance. CONCLUSION: This retrospective study suggested that using sugammadex reversal in cardiac surgical patients undergoing cardiopulmonary bypass may result in more patients meeting the Society of Thoracic Surgery benchmark extubation criteria within 6 hours of the end of surgery.

Incidence and characteristics of patients presenting with acute myocardial infarction and non-obstructive coronary artery disease.

OBJECTIVES: This study aimed to characterize the etiologies of patients presenting with myocardial infarction (MI) and found to have non-obstructive coronary artery disease (NOCAD) and compare risk factors and in-hospital mortality to those with obstructive coronary artery disease (CAD). BACKGROUND: Patients presenting with an MI are often found to have NOCAD defined as less than 50% luminal diameter reduction by visual estimation on coronary angiography. METHODS: This study is a retrospective analysis of a total of 2,038 patients that presented to NorthShore University HealthSystem with MI and underwent coronary angiography from 2010 to 2013. RESULTS: 1,822 patients (89%) had CAD and 216 (11%) had NOCAD. Of the NOCAD patients, the most common etiologies were Takotsubo cardiomyopathy (28%), no alternative explanation (26%), demand ischemia (21%), myopericarditis (7%), coronary artery vasospasm (5%), and coronary artery dissection (3%). NOCAD patients were more likely to be younger and female. There was no significant difference between NOCAD and CAD patients in terms of in-hospital mortality (3.7% vs. 4.0% respectively, OR = 1.1, 95% CI 0.5-2.3, P = 0.83 by univariate logistic regression, OR = 1.2, 95% CI 0.5-3.1, P = 0.74 by multivariable analysis). CONCLUSIONS: CAD patients were more likely to have traditional risk factors of diabetes, hypertension, hypercholesterolemia, previous MI, previous revascularization with percutaneous coronary intervention or coronary artery bypass graft surgery. Patients presenting with MI and NOCAD were found to have several different etiologies on coronary angiography with the most common being Takotsubo cardiomyopathy.
