Abstract：Objective To explore the prediction value of QRS-T angle of electrocardiogram combined with admission hypersensitive C-reactive protein (hs-CRP) in patients with coronary heart disease complicated with malignant arrhythmia after percutaneous coronary intervention. Methods A total of 72 patients with coronary heart disease admitted to Rugao Hospital of Traditional Chinese Medicine, Jiangsu Province from August 2016 to July 2021 were selected as the study subjects. According to whether the patients were complicated with malignant arrhythmia within one month after percutaneous coronary intervention, they were divided into combined group (27 cases) and uncombined group (45 cases). The medical records, hematological indexes, and QRS-T angle of electrocardiogram after admission were compared between the two groups, the related influencing factors postoperative malignant arrhythmia in patients with coronary heart disease after percutaneous coronary were analyzed, and the predictive value of QRS-T angle of electrocardiogram and admission hs-CRP level for postoperative malignant arrhythmia in patients with coronary heart disease were evaluated. Results The proportion of smoking history, proportion of blood potassium level ＜ 3.5 mmol/L, QRS-T angle, and admission hs-CRP level in the combined group were higher than those in the uncombined group, the differences were statistically significant (P ＜ 0.05). Multivariate results showed that smoking history, blood potassium level < 3.5 mmol/L, QRS-T angle of electrocardiogram, and admission hs-CRP level were the influencing factors of postoperative malignant arrhythmia in patients with coronary heart disease after percutaneous coronary intervention (P ＜ 0.05). The predictive value of QRS-T angle combined with admission hs-CRP level in patients with coronary heart disease after percutaneous coronary intervention was higher than that of the two alone (P ＜ 0.05). Conclusion QRS-T angle of electrocardiogram combined with admission hs-CRP level has high predictive efficacy in patients with coronary heart disease after percutaneous coronary intervention complicated with malignant arrhythmia, which is worthy of further promotion.
