Effect of PCI on left ventricular diastolic function in the old people with acute myocardial infarction / 中国综合临床

ABSTRACT

Objective To compare the the effect of PCI on short term (3 months) left ventricular diastolic function in the old patients with acute myocardial infarction (AMI) (≥ 65 years old). Methods 40 old AMI patients were divided into PCI group and non-operation group (pure medicine treatment group). The changes of left ventricular diastolic function were observed 3 months after operation which were compared with that before treatment so to define the effect of PCI. The major indexes were LA, LV, LVEF, E/A, and S/D. Results LA and LV in PCI group were not significandy changes but they were increased in non-operation group (P < 0.05). Although the left ventricular diastolic function in both group was continually impaird,it was better in PCI group than in non-operation greup(P <0.05). Conclusion PCI can prolong the progress of left heart remodeling and the excerbation of left ventricular diastolic function in old AMI patients.
