Influence of PCI on plasma B-type natriuretic peptide in patients with acute ST elevated myocardial infarction / 中国介入心脏病学杂志

ABSTRACT

Objective To investigate whether emergency percutaneous coronary intervention(PCI) could influence the BNP level in patients with ST-segment elevation myocardial infarction(STEMI).Methods We enrolled 193 patients who were admitted with STEMI.The BNP levels were measured at admission.All patients underwent routine clinical laboratory tests in the first day of hospitalization.Ninety-two patients underwent emergency PCI and the other 101 patients received conservative medicine treatment.The patients who had emergency PCI were divided into two subgroups according to the time between symptom onset and PCI started(ictus time 0-3 h,n=42;ictus time 3-6 h,n=50) for analysis.Results BNP levels were significantly lower in patients undergoing PCI when compared with conservative medicine treatment(261.0?410.9 ng/L vs 921.5?1126.7 ng/L,P
