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.
