[Short-term effect of percutaneous transluminal coronary angioplasty with stent implantation in treating myocardial infarction with severe pump failure].
OBJECTIVE
To evaluate the short-term therapeutic effect of percutaneous transluminal coronary angioplasty (PTCA) with stent implantation in the treatment of myocardial infarction with severe pump failure.


METHODS
The clinical data of 73 patients receiving PTCA and stent implantation for myocardial infarction with severity pump failure were analyzed and grouped according the occurrence of complications, degree of the vascular lesions and the complexity of the surgical procedures. Preoperative and postoperative ventricular ejection fractions (LVEF) were compared in each case.


RESULTS
The degree of vascular lesions and surgical complexity were not shown to relate to the occurrence of the complications. Except in cases complicated by chronic renal dysfunction, significant improvement was achieved in the patients 7 d after the operation (P<0.05), regardless of different degrees of vascular lesions and surgical complexity.


CONCLUSIONS
PTCA with stent implantation is effective to improve the short-term cardiac function of patients with myocardial infarction and severe pump failure.
