ObjectiveTo evaluate the value of myocardial perfusion change before and after coronary artery bypass grafting (CABG) in predicting postoperative major adverse cardiovascular events (MACE).MethodsA total of 70 CABG patients who received CABG completed by the same operator from January to November 2017 were selected, including 45 males and 25 females with an average age of 64.83±9.09 years. The patients were divided into two groups according to whether the patients had MACE after 1 year of the surgery, including a non-MACE group (group A, n=60) and a MACE group (group B, n=10). The clinical data of patients were compared.ResultsThere were statistical difference in the myocardial contrast echocardiography (MCE) score in the group A before and after surgery (P<0.05), and there were statistically significant differences in the left ventricular size and left ventricular ejection fraction (LVEF) value before and 1 year after surgery (P<0.001), but no statistically significant difference in the size of left atrium (P=0.075). There was no significant difference in the preoperative and postoperative MCE score, and preoperative and postoperative 1-year cardiac ultrasound score in the group B (P>0.05).ConclusionThe change of myocardial perfusion after CABG surgery is associated with postoperative MACE. The evaluation of myocardial perfusion before and after CABG surgery is of great significance for the prognosis evaluation of patients.
ObjectiveTo explore the risk factors and countermeasures of the perfusionist-related near-miss event (NME) in cardiopulmonary bypass (CPB). MethodsThe clinical data of the patients who underwent cardiac surgery in the Department of Cardiovascular Surgery, Nanfang Hospital, Southern Medical University from March 2020 to July 2021 were retrospectively analyzed. According to whether NME occurred during the operation, the patients were divided into an NME group and a non-NME group. The clinical data of the two groups were compared, and the risk factors for NME were analyzed. ResultsA total of 702 patients were enrolled, including 424 males and 278 females with a median age of 56.0 years. There were 125 patients in the NME group and 577 patients in the non-NME group. The occurrence rate of NME was 17.81%. Univariate analysis showed that there were statistical differences between the two groups in the gender, body surface area, CPB time, European system for cardiac operative risk evaluation score, emergency surgery, type of surgery, night CPB initiation, modified ultrafiltration use, multi-device control, average operation time, et al. (all P<0.05). The above variables were dimensionality reduction processed by least absolute shrinkage and selection operator regression, and the λ of minimum mean square error of 10-fold cross validation was 0.014. The variables of the corresponding model were selected as follows: multi-device control, night CPB initiation, minimum hematocrit, modified ultrafiltration use, CPB time. The results of multivariate logistic regression showed that night CPB initiation [OR=9.658, 95%CI (4.735. 19.701), P<0.01] and CPB time [OR=1.003, 95%CI (1.001, 1.006), P=0.014] were independent risk factors for NME. ConclusionNight CPB initiation and CPB time are independent risk factors for NME during CPB, which should be recognized and early warned in clinical work.
Endoscopic retrograde cholangiopancreatography (ERCP) is currently the first-line minimally invasive diagnosis and treatment of biliary and pancreatic diseases. With the increasing popularity of ERCP, ERCP-related adverse events which include post-ERCP pancreatitis, cholecystitis, cholangitis, bleeding, perforation, etc., have received more and more attention. In response to the controversy and problems in the management of these adverse events, the European Society of Gastrointestinal Endoscopy published the guidelines for ERCP-related adverse events in December 2019. The paper interprets the key points in the guideline to provide references for clinical practice.
ObjectiveTo design and use adverse nursing events information management system to improve the quality of nursing for high-risk patients and guarantee nursing quality and safety. MethodAdverse nursing events information management system was started from January 2014. Two hundred cases assessed to be nursing adverse events cases from September to December 2013 were chosen to form the control group, and another 200 from the same period in 2014 were designated to be the observation group. Then we compared the two groups in terms of the onset time of nursing assessment, incidence of adverse nursing events and rate of missing reports. ResultsThe onset time of nursing assessment, incidence of adverse events, and the rate of missing reports were significantly lower in the observation group than the control group (P<0.05). ConclusionsThe application of adverse nursing events information management system can improve the quality of nursing management and promote the nursing quality and safety.

Objective To explore the relationship between macro-economic indicators and incidences of adverse events linked to intrauterine devices (IUDs). Methods Data on IUD-associated adverse events were collected from a cohort study conducted between September 2005 and December 2006. Regional economic data were from the 2006 National Economic and Social Development Statistical Bulletins and Statistical Yearbooks of various regions. A total of 20,220 IUD users in 236 towns in Jiangsu, Shanghai, Guangdong, Anhui, Sichuan, and Chongqing provinces in China were included in this study. Linear correlation and regression analyses were used to analyze the relationships between regional income and total incidences of adverse events, incidences of mild adverse events, and incidences of severe adverse events. Results Incidences of total adverse events and mild adverse events were positively correlated with regional economic level (rs=0.336, Plt;0.05; rs=0.272, Plt;0.05), while incidences of severe adverse events were not correlated with regional economic level. Conclusions The positive relationship between regional economic level and reported IUD-associated mild adverse events likely reflects income-related disparities in women seeking care and receiving treatment for mild adverse events. This points to a need to improve both public health education and the quality of health services, particularly in poorer areas.
ObjectiveTo investigate the impact of clopidogrel resistance on the long-term prognosis in the elderly with acute coronary syndrome (ACS), as clopidogrel is widely used for secondary prevention in the patients with ACS, while studies on the relationship between clopidogrel resistance and long-term outcome in the elderly with ACS are limited. MethodsThree hundred elderly patients with ACS, aged from 70 to 95, with on average age of (81.3±6.4) years old, receiving clopidogrel (75 mg, once a day) over one month between January 2009 and December 2010 were followed up for major adverse cardiac events (MACE, including cardiac death, non-fatal re-myocardial infarction, angina, ischemia stroke/TIA, acute thrombosis and hemorrhage). Platelet aggregation was measured by light transmission aggregometry using adenosine diphosphate as a stimulus. According to the variation of platelet aggregation, the patients were divided into clopidogrel resistance group (<10%) and non-lopidogrel resistance group (≥10%). The median follow-up was 2 years. A Cox hazard proportional model was used to estimate time to outcome associated with clopidogrel resistance and MACE. ResultsThe incidence of clopidogrel resistance was 24.0% in our study population. Patients with diabetes, renal insufficiency, or a higher body mass index tended to have clopidogrel resistance. Compared with those patients without clopidogrel resistance, there was significantly increased MACE in patients with clopidogrel resistance (37.5%, 22.8%; P=0.032). Additionally, Cox hazard proportional model analysis demonstrated that clopidogrel resistance was an independently risk factor for MACE[HR=2.34, 95% CI (1.07, 4.57), P=0.016]. ConclusionDiabetes, renal insufficiency and high body max index are associated with clopidogrel resistance, which can predict the increased risk of MACE in elderly patients with ACS.
Objective To construct a risk prediction score model for serious adverse event (SAE) after cardiac catheterization in patients with adult congenital heart disease (ACHD) and pulmonary hypertension (PH) and verify its predictive effect. Methods The patients with PH who underwent cardiac catheterization in Wuhan Asian Heart Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to January 2022 were retrospectively collected. The patients were randomly divided into a model group and a validation group according to the order of admission. The model group was divided into a SAE group and a non-SAE group according to whether SAE occurred after the catheterization. The data of the two groups were compared, and the risk prediction score model was established according to the results of multivariate logistic regression analysis. The discrimination and calibration of the model were evaluated using the area under the receiver operating characteristic (ROC) curve and the Hosmer-Lemeshow test, respectively. Results A total of 758 patients were enrolled, including 240 (31.7%) males and 518 (68.3%) females, with a mean age of 43.1 (18.0-81.0) years. There were 530 patients in the model group (47 patients in the SAE group and 483 patients in the non-SAE group) and 228 patients in the validation group. Univariate analysis showed statistical differences in age, smoking history, valvular disease history, heart failure history, N-terminal pro-B-type natriuretic peptide, and other factors between the SAE and non-SAE groups (P<0.05). Multivariate analysis showed that age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, surgical general anesthesia, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients (P<0.05). The risk prediction score model had a total score of 0-139 points and patients who had a score>50 points were high-risk patients. Model validation results showed an area under the ROC curve of 0.937 (95%CI 0.897-0.976). Hosmer-Lemeshow goodness-of-fit test: χ2=3.847, P=0.797. Conclusion Age≥50 years, history of heart failure, moderate to severe congenital heart disease, moderate to severe PH, cardiac catheterization and treatment, general anesthesia for surgery, and N-terminal pro-B-type natriuretic peptide≥126.65 pg/mL were risk factors for SAE after cardiac catheterization for ACHD-PH patients. The risk prediction model based on these factors has a high predictive value and can be applied to the risk assessment of SAE after interventional therapy in ACHD-PH patients to help clinicians perform early intervention.
