雙腔起搏治療對急性下壁心梗合并三度房室傳導阻滯患者的影響
[Abstract]:Objective to study the effects of dual chamber pacing on serum brain natriuretic peptide (BNP), cardiac troponin level and cardiac function in patients with acute inferior myocardial infarction (AMI) complicated with three degree atrioventricular block (AVB). Methods the serum levels of brain natriuretic peptide and cardiac troponin in patients with acute inferior wall infarction complicated with three degree atrioventricular block (observation group) and healthy subjects (control group) before and after treatment were compared. The level of cardiac function before and after treatment, To analyze the correlation between ejection fraction (LVEF) and peak velocity of mitral valve (E) / late diastolic peak velocity (A) (E / A) and ra after treatment. Results after treatment, the levels of serum brain natriuretic peptide and cardiac troponin in the observation group were significantly decreased, but still higher than those in the control group (P0.05). In the observation group, the levels of E / Agna LVEF and Sra were significantly higher than those of 1 day after operation, and the levels of LAVmin and LAVmax decreased significantly at 3 months after operation as compared with 1 day before operation, and the level of Lef increased significantly at 3 months after operation compared with that on the 1st day before operation, and the levels of LAVmin and LAVmax were significantly lower in the observation group than in the first day before operation. The difference was statistically significant (P0.05). LVEF was positively correlated with Sra level. Conclusion Dual-chamber pacing can significantly improve the serum levels of brain natriuretic peptide and cardiac troponin and improve cardiac function in patients with acute inferior wall infarction complicated with three degree atrioventricular block.
