目的 :研究经皮冠状动脉腔内成形术 (PTCA)对急性心肌梗死 (AMI)患者短期内心功能的影响。方法 :以CF -II型心血管功能检诊仪对 2 4例AMI患者进行动态监测 ,术前 1日及术后第 1、2、3、5、7日检测血流动力学各参数。结果 :患者的血流动力学参数在PTCA术后第 1、2、3日较术前明显恶化 ,术后第 7日参数已恢复甚至优于术前水平。患者术后 1周内的心功能动态演变呈“U”型趋势曲线。结论 :AMI患者在PTCA术后可出现短暂而可逆的心功能障碍 ,尤其在术后 3日内心功能下降最明显。因此 ,加强和维护患者术后的心功能仍应是此期医疗和护理的重点。
Objective: To study the effect of percutaneous transluminal coronary angioplasty (PTCA) on the short-term cardiac function in patients with acute myocardial infarction (AMI). Methods: Twenty-four patients with AMI underwent dynamic monitoring with CF-II cardiovascular function test instrument. The parameters of hemodynamics were detected on the 1st, 2nd, 3rd, 5th and 7th days before operation. Results: The hemodynamic parameters of patients were significantly worse than those before operation on the 1st, 2nd and 3rd days after PTCA. The parameters on the 7th day after operation were restored or even better than the preoperative levels. The dynamic evolution of cardiac function in patients within 1 week after surgery was “U” trend curve. Conclusion: Short-term and reversible cardiac dysfunction may occur in AMI patients after PTCA, especially in the third day after operation. Therefore, to strengthen and maintain the patient’s cardiac function after surgery should still be the focus of medical and nursing.
