41例风湿性心脏病(风心病)二尖瓣病变患者(房颤29例,窦性心律12例)行心脏外科手术时取右心耳组织,用V-G染色法和V IDA S-21图像分析系统测量其心房组织胶原容积分数(CVF)。结果房颤患者的心房组织CVF明显高于窦性心律患者(P<0.05)。房颤患者均转复为窦性心律,随访12个月后,维持窦性心律20例,转为房颤9例;房颤复发患者的心房组织CVF、房颤持续时间和左房内径均明显大于维持窦性心律患者(P<0.05)。提示心房纤维化程度可能是影响风心病房颤患者复律后窦性心律维持的因素之一。
目的:分析急性心肌梗死(AMI)患者药物涂层球囊(DCB)治疗术后1年发生MACE事件的危险因素。方法:连续性纳入2021年1月~2023年12月于青岛市海慈医院心内科行DCB治疗的AMI患者192例。根据患者DCB治疗后1年MACE事件发生情况,将其分为非MACE组(156例)和MACE组(36例)。收集患者一般资料、术中术后资料、治疗情况、1年随访情况等资料,采用Cox回归分析分析AMI患者DCB治疗后发生MACE事件的影响因素,绘制受试者工作特征(ROC)曲线,评估影响因素的预测效能。结果:多因素Cox回归分析显示,STEMI (HR = 2.187, 95%CI = 1.016~4.708, P Objective: To analyze the risk factors for Major Adverse Cardiovascular Event (MACE) in patients with Acute Myocardial Infarction (AMI) who underwent Drug-Coated Balloon (DCB) treatment within 1 year. Methods: 192 patients with AMI who underwent DCB treatment in the Cardiology Department of Qingdao Haici Hospital from January 2021 to December 2023 were continuously enrolled. According to 1-year MACE event incidence after DCB treatment, they were divided into the non-MACE group (156 cases) and the MACE group (36 cases). The patients’ general information, intraoperative and postoperative information, treatment situation, and 1-year follow-up information were collected, and Cox regression analysis was used to analyze the influencing factors of MACE events in patients with AMI after DCB treatment, and the Receiver Operating Characteristic (ROC) curve was drawn to evaluate the predictive ability of the influencing factors. Results: The multivariate Cox regression analysis showed that STEMI (HR = 2.187, 95% CI=1.016~4.708, P < 0.05) and target vessel as LCX (HR = 0.021, 95% CI = 0.006~0.070, P < 0.05) and RCA (HR = 0.028, 95% CI = 0.010~0.083, P < 0.05) were independent predictors of MACE events in patients with AMI after DCB treatment within 1 year. The ROC curve analysis showed that the predictive ability of combined STEMI and target vessel as RCA and LCX in predicting MACE e
