RÉSUMÉ
Objective:To investigate atrial fibrillation patients′illness perception during the blanking period after pulmonary vein isolation (PVI) and to analyze its influencing factors, so as to provide a reference for improving patients′cognition of the disease and speeding up the rehabilitation process.Methods:This study was a cross-sectional survey. Convenience sampling method was adopted to select 320 patients with atrial fibrillation who were reexamined in the outpatient department during the blanking period after PVI from Affiliated Hospital of Qingdao University from Auguest 2022 to May 2023 as the research subjects. The General Information Questionnaire, the Brief Illness Perception Questionnaire (BIPQ), and the Control Attitudes Scale-Revised (CAS-R) were used for on-site investigation.Results:Totally 320 patients were included in this study, including 177 males and 143 females, aged (61.64 ± 10.74) years old. The total score of BIPQ was (42.98 ± 10.49) points, the total score of CAS-R was (27.20 ± 5.65) points. The results of multiple linear regression analysis showed that age, resting heart rate, postoperative course, and perceived control were the influencing factors of illness perception ( F = 25.24, P<0.05). Conclusions:The illness perception of atrial fibrillation patients during the blanking period after PVI needs to be improved urgently. Medical staff should pay more attention to patients with old age, fast resting heart rate, short postoperative course, and low perceived control, and take effective measures to reduce negative illness perception and promote postoperative rehabilitation.
RÉSUMÉ
Objective To evaluate the short-term prediction of high-sensitivity cardiac troponin T (hs-cTnT) and other cardiovascular risk biomarkers in patients undergoing maintenance hemodialysis (MHD).Methods We conducted a cohort survey in 296 consecutive MHD patients whose clinical data were retrospectively analyzed.Before MHD,hs-cTnT and other relative cardiovascular biomarkers were detected.The end point (all-cause death) and time of occurring were recorded in the next 13 months.The differences between survival and all-cause death were analyzed by t-test,Mann-Whitney test and x2 test.The best two percentile cutoff point was calculated by X-tile and the survival rate was calculated by Kaplan-Meier Logistic regression analysis was applied to analyze the odd ratio between high risk and non-high risk hs-cTnT group.Non-high risk group was divided into intermediate risk and low risk group based on the 99th percentile of hs-cTnT in healthy population,to further evaluate its short-term prediction value for MHD patients.The short-term significance of hs-cTnT was proved to be independently associated with all-cause death by Logistic regression analysis.Results The mean value of serum hs-cTnT in survival group was 0.05 (0.03～0.07) ng/mL,while in the death group it was 0.07 (0.04～0.14) ng/mL,which had statistical significance (P =0.027).The best two percentile cutoff of hs-cTnT in MHD patients was 0.1 ng/mL.The survival rate in high risk group (hs-cTnT＞0.1 ng/mL) is lower than it in non-high risk group (hs-cTnT≤0.1 ng/mL) (76.67％ vs.96.62％,P ＜0.05).The odd ratios for high risk group and non-high risk group was 7.288 (P＜ 0.001).Moreover,further grouping the non-high risk group by hs-cTnT =0.014 ng/mL,intermediate risk group (hs-cTnT＞0.014 ng/mL) group has lower survival rate than low risk group (hs-cTnT≤0.014ng/mL),while there wasn't any death case occurred in the low risk group.Conclusions Hs-cTnT is an independent risk factor to all-cause death.Thus hs-cTnT can be a strong indicator of short-term prediction and prognostic evaluation.
