目的：评价风心病心肌病理损害与术后早期心功能的关系，指导围术期治疗。方法：３３例风心病患者分为二尖瓣狭窄组（ｎ＝１６）和二尖瓣关闭不全组（ｎ＝１７），观察其心肌病理损害变化；用Ｓｗａｎ－Ｇａｎｚ导管测量术后７２ｈ心排量和心脏指数。结果：心肌病理损害愈重，术后早期心功能恢复愈慢，反之亦然。结论：术后早期心功能的恢复与心肌病理损害程度有关。
Objective: To evaluate the relationship between myocardial pathological lesions of rheumatic heart disease and early postoperative cardiac function, and to guide the perioperative treatment. Methods: Thirty-three patients with rheumatic heart disease were divided into mitral stenosis group (n = 16) and mitral regurgitation group (n = 17), and their myocardial pathological changes were observed. Swan- Volume and heart index. Results: The more severe the pathological changes of heart muscle, the slower the recovery of cardiac function in the early postoperative period and vice versa. Conclusion: The recovery of early postoperative cardiac function is related to the degree of myocardial pathological damage.
