RESUMEN
Blood group is a potential genetic element in coronary artery disease. Nevertheless, the relationship between different ABO blood groups and myocardial injury after non-cardiac surgery (MINS) is poorly understood. This study verified whether ABO blood group is a potential MINS influencing factor. This retrospective cohort study included 1201 patients who underwent elective non-cardiac surgery and a mandatory troponin test on postoperative days 1 and 2 from 2019 to 2020 at a university-affiliated tertiary hospital. The primary outcome was associations between ABO blood groups and MINS, assessed using univariate and multivariate logistic-regression analyses. Path analysis was used to investigate direct and indirect effects between blood group and MINS. MINS incidence (102/1201, 8.5%) was higher in blood-type B patients than in non-B patients [blood-type B: 44/400 (11.0%) vs. non-B: 58/801 (7.2%); adjusted odds ratio = 1.57 (1.03-2.38); p = 0.036]. In the confounding factor model, preoperative hypertension and coronary artery disease medical history were associated with MINS risk [adjusted odds ratio: 2.00 (1.30-3.06), p = 0.002; 2.81 (1.71-4.61), p < 0.001, respectively]. Path analysis did not uncover any mediating role for hypertension, diabetes, or coronary artery disease between blood type and MINS. Therefore, blood-type B is associated with higher MINS risk; potential mediators of this association need to be investigated.

PURPOSE: The purpose of this study was to analyze the reliability and validity of the Perioperative Anxiety Scale-7 (PAS-7), which was created by Chinese medical professionals, by using the State-Trait Anxiety Scale (STAI-S) as the standard for the diagnosis of preoperative anxiety, and to compare whether there is a difference between the PAS-7 and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) in the diagnosis of preoperative anxiety in the Chinese population. DESIGN: This study was an observational study. METHODS: The PAS-7, APAIS, and STAI-S were all completed the day before surgery. The internal consistency test was used to evaluate the scale's reliability, and exploratory factor analysis and confirmatory factor analysis were used to assess the scale's construct validity. Pearson correlation was used to analyze the correlation between PAS-7 and STAI-S, and APAIS. The area under the receiver operating characteristic (ROC) curve was used to compare the diagnostic value of PAS-7 and APAIS. FINDINGS: The PAS-7 Cronbach's α coefficient was 0.804. The indicators of the overall fitting coefficient were within the acceptable range. PAS-7 scores correlated well with STAI-S and APAIS scores (P < .01). The area under the ROC curve of PAS-7 was 0.808 (0.752-0.856), and the area under the ROC curve of APAIS was 0.674 (0.611-0.733). The difference between areas was 0.133 (0.0612-0.206), P < .001, and the diagnostic value of PAS-7 was higher than that of APAIS. CONCLUSIONS: The PAS-7 scale has high reliability and validity and can be used to assess preoperative anxiety in patients undergoing elective surgery. PAS-7 is superior to APAIS for assessing preoperative anxiety in the Chinese population.
