【摘要】 目的 觀察原發性高血壓左心室肥厚患者的心律失常情況。 方法 對2000年1月-2009年10月收治的251例原發性高血壓患者進行超聲心動圖及Holter檢查，比較有左心室肥厚（left ventricular hypertrophy，LVH）及無LVH兩組各類心律失常的發生情況。 結果 LVH組各種心律失常的發生率與非LVH組比較，差異有統計學意義（Plt;0.01）。LVH組室性心律失常及復雜性室性心律失常的檢出率為83.33%和51.85%，明顯高于非LVH組（28.67%和9.09%），差異有統計學意義（Plt;0.01）。 結論 高血壓并發LVH與心律失常的發生有一定密切關系。【Abstract】 Objective To analyze the condition of arrhythmia in the patients with primary hypertension combined with left ventricular hypertrophy. Methods A total of 251 patients with primary hypertension from January 2000 to October 2009 were selected. All the patients had undergone the examinations of ultrasonic cardiogram, 12-lead electrocardiogram and Holter test to compare the incidence of arrhythmia between LVH and non-LVH group. Results There were significant differences in the incidences of arrhythmia between the two groups (Plt;0.01). Furthermore, the incidence of ventricular arrhythmias and complexity of ventricular arrhythmias of the patients in LVH group was 83.33% and 51.85% respectively, significantly higher than that in non-LVH group (28.67% and 9.09%; Plt;0.01). Conclusion Primary hypertension combined with LVH is relevant to arrhythmias.
目的:了解阻塞性睡眠呼吸暫停綜合癥(OSAHS)患者夜間心律失常的發生情況、常見類型及相關因素。方法:對67例睡眠打鼾患者同步進行動態心電圖及多導睡眠圖監測。以呼吸暫停指數及夜間最低氧飽和度將研究對象進行分組,比較分析夜間心律失常發生率及發生類型并進一步分析夜間心律失常的相關因素。結果:OSAS組的夜間心律失常發生率顯著高于單純鼾癥患者。隨著OSAS加重,呼吸暫停低通氣指數逐漸增大,夜間氧飽和度下降越明顯,心律失常發生率升高,發生時間延長、惡性程度增加,尤其以緩慢型心律失常的發生率增多。結論:OSAHS患者夜間心律失常的發生率及嚴重程度與OSAHS嚴重程度呈正相關,夜間心律失常的誘發與呼吸暫停低通氣指數及低氧血癥密切相關。應重視夜間心律失常患者合并存在的OSAHS的診治。
Objective To investigate the risk factors for arrhythmia after robotic cardiac surgery. Methods The data of the patients who underwent robotic cardiac surgery under cardiopulmonary bypass (CPB) from July 2016 to June 2022 in Daping Hospital of Army Medical University were retrospectively analyzed. According to whether arrhythmia occurred after operation, the patients were divided into an arrhythmia group and a non-arrhythmia group. Univariate analysis and multivariate logistic analysis were used to screen the risk factors for arrhythmia after robotic cardiac surgery. ResultsA total of 146 patients were enrolled, including 55 males and 91 females, with an average age of 43.03±13.11 years. There were 23 patients in the arrhythmia group and 123 patients in the non-arrhythmia group. One (0.49%) patient died in the hospital. Univariate analysis suggested that age, body weight, body mass index (BMI), diabetes, New York Heart Association (NYHA) classification, left atrial anteroposterior diameter, left ventricular anteroposterior diameter, right ventricular anteroposterior diameter, total bilirubin, direct bilirubin, uric acid, red blood cell width, operation time, CPB time, aortic cross-clamping time, and operation type were associated with postoperative arrhythmia (P<0.05). Multivariate binary logistic regression analysis suggested that direct bilirubin (OR=1.334, 95%CI 1.003-1.774, P=0.048) and aortic cross-clamping time (OR=1.018, 95%CI 1.005-1.031, P=0.008) were independent risk factors for arrhythmia after robotic cardiac surgery. In the arrhythmia group, postoperative tracheal intubation time (P<0.001), intensive care unit stay (P<0.001) and postoperative hospital stay (P<0.001) were significantly prolonged, and postoperative high-dose blood transfusion events were significantly increased (P=0.002). Conclusion Preoperative direct bilirubin level and aortic cross-clamping time are independent risk factors for arrhythmia after robotic cardiac surgery. Postoperative tracheal intubation time, intensive care unit stay, and postoperative hospital stay are significantly prolonged in patients with postoperative arrhythmia, and postoperative high-dose blood transfusion events are significantly increased.
Objective To analyze the risk factors affecting the occurrence of arrhythmia after esophageal cancer surgery, construct a risk prediction model, and explore its clinical value. Methods A retrospective analysis was conducted on the clinical data of patients who underwent radical esophagectomy for esophageal cancer in the Department of Thoracic Surgery at Anhui Provincial Hospital from 2020 to 2023. Univariate and multivariate analyses were used to screen potential factors influencing postoperative arrhythmia. A risk prediction model for postoperative arrhythmia was constructed, and a nomogram was drawn. The predictive performance of the model was then validated. Results A total of 601 esophageal cancer patients were randomly divided into a modeling group (421 patients) and a validation group (180 patients) at a 7 : 3 ratio. In the modeling group, patients were further categorized into an arrhythmia group (188 patients, 44.7%) and a non-arrhythmia group (233 patients, 55.3%) based on whether they developed postoperative arrhythmia. Among those with postoperative arrhythmia, 43 (10.2%) patients had atrial fibrillation (AF), 12 (2.9%) patients had atrial premature beats, 15 (3.6%) patients had sinus bradycardia, and 143 (34%) patients had sinus tachycardia. Some patients exhibited multiple arrhythmias, including 14 patients with AF combined with sinus tachycardia, 7 patients with AF combined with atrial premature beats, and 3 patients with AF combined with sinus bradycardia. Univariate analysis revealed that a history of hypertension, heart disease, pulmonary infection, acute respiratory distress syndrome, postoperative hypoxia, anastomotic leakage, and delirium were risk factors for postoperative arrhythmia in esophageal cancer patients (P<0.05). Multivariate logistic regression analysis showed that a history of heart disease, pulmonary infection, and postoperative hypoxia were independent risk factors for postoperative arrhythmia after esophageal cancer surgery (P<0.05). The area under the receiver operating characteristic curve (AUC) of the constructed risk prediction model for postoperative arrhythmia was 0.710 [95% CI (0.659, 0.760)], with a sensitivity of 0.617 and a specificity of 0.768. Conclusion A history of heart disease, pulmonary infection, and postoperative hypoxia are independent risk factors for postoperative arrhythmia after esophageal cancer surgery. The risk prediction model constructed in this study can effectively identify high-risk patients for postoperative arrhythmia, providing a basis for personalized interventions.
ObjectiveTo analyze the perioperative safety and the short-term prognosis of non-small cell lung cancer (NSCLC) patients with preoperative arrhythmia. MethodsThe clinical data of NSCLC patients treated in the Department of Cardiothoracic Surgery, the First Affiliated Hospital of Chongqing Medical University from August 2020 to March 2021 were collected and observed. The patients were divided into an arrhythmia group and a control group according to whether there was arrhythmia in the 24 h ambulatory electrocardiogram examination report before operation. The incidence of intraoperative and postoperative cardiovascular events and short-term prognosis were compared between the two groups. Results A total of 466 patients were included in this study, including 338 patients in the arrhythmia group, 176 males and 162 females, with a median age of 68.0 (63.0, 72.0) years, and 128 patients in the control group, 59 males and 69 females, with a median age of 66.5 (60.0, 72.0) years. A total of 26 patients (7.7%) in the arrhythmia group were placed with temporary pacemakers before operation. There was no significant difference in the incidence of cardiovascular related events between the two groups [100 (29.6%) vs. 28 (21.9%), P=0.096]. The incidence of postoperative arrhythmia events in the arrhythmia group was higher than that in the control group [112 (33.1%) vs. 11 (8.6%), P<0.001]. The average postoperative ICU stay in the arrhythmia group was longer than that in the control group (1.1±0.7 d vs. 1.0±0.6 d, P=0.039). ConclusionPreoperative arrhythmia does not increase the risk of intraoperative cardiovascular events in NSCLC patients, but increases the incidence of postoperative arrhythmia events and prolongs ICU stay.
