PCI for Cardiac Function in Patients with Non ST Segment Elevation Myocardial Infarction

Objective To evaluation of non ST segment elevation myocardial infarction(NSTEMI),direct percutaneous coronary intervention(PCI) treatment and conservative treatment for patients on left ventricular function.Methods 36 NSTEMI patients treated by PCI were as treatment group,at the same period 26 cases of simple application of drugs to treat the patients with NSTEMI as drug treatment group,two groups of patient age,gender and disease were matched.Before operation(drug therapy),after 3 days and 1 month after the measurement,plasma BNP levels in patients were detected.Preoperative PCI(or prior drug treatment) and after(or drugs) for 1 months and 3 months,patients were examined by color Doppler.Comparison of 2 groups of left ventricular end diastolic diameter(LVDd),left ventricular end systolic diameter(LVDs),left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(Fs) changes was performed,and on the basis of clinical performance,NUHA grading of heart function change of 2 groups was compared.Results Two groups of patients plasma BNP concentration decreased,BNP in interventional treatment group decreased more than drug therapy group.Color Doppler detection of various indexes of left ventricular function were obviously improved(P0.05),and interventional treatment group after the March fourth indicators were superior to drug therapy group:LVDd[(45.26 ±12.85) VS(47.71±13.09)mm]、LVDs[(29.75±0.91) VS(31.06±0.61)mm]、LVEF[(55.52±5.25)% VS(46.62±6.52)%]和FS[(26.27±6.83)% VS(23.98±3.05)%](P0.05).Interventional therapy group classification of NYHA was also superior to drug therapy group.Conclusion As a simple drug conservative treatment,PCI was more beneficial to protect NSTEMI of left heart function in patients with.
