To observe impact of late percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) on ventricular remodeling.
Between June 2013 and March 2015, chose 58 patients treated with late PCI during 7 days and 3 months after AMI, and 50 patients without PCI after AMI as control group. Optimal therapy for all patients included drugs known to carry prognostic benefits after AMI. Both groups took 99TCm-MIBI myocardial perfusion imaging test assessing left ventricular size and function at 1 month and 9 months after AMI. Regarding left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF).
LVEDV, LVESV and LVEF were similar between the two groups in 1 month after AMI. However, significant changes in LVEDV[(102.6±25.6)ml vs (117.2±28.5)ml P=0.035] and LVESV [(55.1±20.6)ml vs (66.4±28.7)ml P=0.043] were observed within two groups at 9 months，and the LVEF of PCI group increased dramatically than control group [(56.1±9.6)% vs (47.4±13.2)% P=0.006].
Late percutaneous coronary intervention in patients with AMI is an effective therapy, prevent ventricular remodeling efficiently and protect left ventricular function.
