摘要 目的:分析心电图V1导联P波终末电势(PTFV1)对冠心病患者脑卒中的影响。方法:采用回顾性分析法,对2018年1月至2021年1月期间我院收治的122例冠心病患者的临床资料进行分析,所有患者均接受12导联心电图和心脏磁共振检查。依据PTFV1水平对122例患者进行分组,其中A组(>-0.03mm·s,n=42)、B组(P波直立,以0计算,n=40)、C组(≤-0.03mm·s,n=40)。对各组患者的一般资料、LA和LV结构和功能参数、肺主动脉主干内径和右心房/室结构、血清相关指标水平、随访8个月的冠心病、脑卒中事件进行比较,并Logistic分析冠心病患者发生脑卒中的相关因素。结果:与C组比较,A组和B组的LA Vmin指数水平均降低,LAEF水平均升高,差异有统计学意义(P<0.05)。与C组比较,A组和B组的右心房心尖四腔短径、右心室短轴流出道内径、右心室心尖四腔长径水平均降低,差异有统计学意义(P<0.05)。与C组比较,A组和B组的血清IMD、Salusin-α水平均升高,血清CysC、CST、NT-proBNP水平均降低,差异有统计学意义(P<0.05)。随访8个月,C组的冠心病事件发生率为10%,脑卒中事件发生率为5%,与C组相比,A组和B组的冠心病事件和脑卒中事件发生率均降低,。PTFV1、右心房心尖四腔短径、右心室短轴流出道内径、右心室心尖四腔长径为冠心病患者发生脑卒中的危险因素(P<0.05)。结论:PTFV1≤-0.03mm·s是冠心病患者脑卒中的主要危险因素,可帮助预测冠心病患者脑卒中的发生。

Abstract：Objective: To analyze the effect of P-wave terminal potential (PTFV1) on stroke in patients with coronary heart disease (CHD). Methods: Using retrospective analysis, the clinical data of 122 patients with coronary heart disease admitted to our hospital from January 2018 to January 2021 were analyzed. All patients received 12-lead electrocardiogram and cardiac magnetic resonance examination. According to the level of PTFV1, 122 patients were divided into groups, including group A (>-0.03mm·s, n=42), group B (P wave upright, calculated as 0, n=40), and group C (≤-0.03mm·s, n=40). The general information, LA and LV structure and function parameters, pulmonary aortic trunk diameter and right atrium/ventricular structure, serum-related index levels, coronary heart disease and stroke events following 3-month follow-up were compared with the general data of each group of patients, and Logistic Factor analysis related factors of stroke in patients with coronary heart disease. Results: Compared with group C, the LA Vmin index level of group A and group B decreased, and the LAEF level increased, the difference was statistically significant (P<0.05). Compared with group C, the four-chamber short diameter of the right atrium apex, the inner diameter of the right ventricular short-axis outflow tract, and the four-chamber long diameter of the right ventricular apex in group A and group B decreased with statistical significance (P<0.05). Compared with group C, serum IMD and Salusin-α levels of group A and group B increased, and serum CysC, CST, and NT-proBNP levels decreased. The difference was statistically significant (P<0.05). After 8 months of follow-up, the incidence of coronary heart disease events in group C was 10%, and the incidence of stroke events was 5%. Compared with group C, the incidence of coronary heart disease events and stroke events in groups A and B were lower. PTFV1, the four-chamber short diameter of the right atrium apex, the inner diameter of the right ventricular short-axis outflow tract, and the four-chamber long diameter of the right ventricular apex were risk factors for stroke in patients with coronary heart disease (P<0.05). Conclusion: PTFV1≤-0.03mm·s is the main risk factor for stroke in patients with coronary heart disease, and it can help predict the occurrence of stroke in patients with coronary heart disease.
