Abstract: Objective To investigate the long-term cardiac structure and cardiac function in acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI). Methods Data from 198 cases of AMI pa-tients, including 93 cases of emergency PCI (group A) and 105 cases of elective PCI (group B), who admitted to Depart-ment of Cardiology of our hospital from July 2013 to July 2015, were retrospectively analyzed. Left atrial diameter (LA), left ventricular diameter (LV), right atrial diameter (RA), right ventricular diameter (RV), left ventricular ejection fraction (LVEF) and ventricular wall motion score indexes of the two groups were respectively measured by echocardiog-raphy and compared at the time of admission and six months after operation. Results The indexes of cardiac function in the two groups were significantly improved after operation in the first half of the year. LVEF of the emergency PCI group was significantly higher than that of the elective PCI group with (58.2±11.3%) vs (54.7±10.3), and LV of the emer-gency PCI group was significantly smaller than that of the elective PCI group with (49.4±5.4) mm vs (53.8±7.2) mm, P<0.05. Conclusion PCI can improve long-term cardiac function and prognosis in AMI patients, and emergency PCI is more advantageous.
