ABSTRACT
Objective To investigate the interventional therapy effect of combination application of thrombus aspiration and intracoronary injection of tirofiban for treating heavy thrombosis burden of infarction related vessel in the patients with acute anterior myocardial infarction.Methods The patients with acute anterior myocardial infarction undergone direct primary percutaneous coronary intervention in the hospital were retrospectively analyzed.The group A received simple thrombus aspiration during transcutaneous PCI and the group B received the combination treatment of thrombus aspiration and intracoronary injection of tirofiban in direct PCI.Results The patients with myocardial perfusion grade less than 3 during thrombolysis during myocardial infarction(TIMI) in the group B were significantly less than those in the group A(P＜0.05).The cardiac magnetic resonance imaging(MRI) results indicated that the area of myocardial infarction in the group B was smaller than that in the group A(P＜0.05).The color echocardiography results showed that the left ventricular diastolic volume(LVDV) and left ventricular ejection fraction(LVEF) in the group B were significantly better than those in the group A(P＜0.05).Conclnsion The combination application of thrombus aspiration and intracoronary injection of tirofiban is safe and effective in direct PCI.
ABSTRACT
Objective To research the combined prognostic utility of NT-proBNP and hs-CTNI in NSTE-ACS risk stratification and early intervention therapy .Methods A total of 245 NSTE-ACS patients were divided to 4 groups(Aa ,Ab ,Ba ,Bb groups) ac-cording to immediate admission NT-proBNP and hs-CTNI .Patients were accepted percutaneous coronary intervention (PCI) ,coro-nary artery bypass grafting and conservative treatment were taken 6 months follow-up .Results The heart failure incidence of Aa group was significantly higher than Ba group(P0 .05) .In 6 months follow-up ,5 patients died and 10 patients accepted revascularization again because of severe angina and AMI .Conclusion In NSTE-ACS patient ,NT-proBNP and hs-CTNI elevation was closely related with severe coronary lesions and worse prediction ,which could undergo early in-tervention therapy .
ABSTRACT
Objective To evaluate the clinical outcomes of emergency intracoronary stenting for senile patients with acute myocardial infarction (AMI). Methods Eighty-four senile patients with AMI underwent emergency intracoronary stenting were compared with eighty-eight non-senile patients with AMI. Results Eighty-six stents were implanted in eighty-four infarction related arteries (IRA), two patients died during hospitalization,the procedural success rate was 97.6% in senile group. Eighty-eight stents were implanted in eighty-eight IRA, one patient died during hospitalization, the success rate was 98.9% in non-senile group. There was no significant difference in characteristic of stents, bleeding complication and LVEF between the senile group and the non-senile group.Conclusion Emergercy intracoronary stenting was an effective and safe therapeutic maneuver for the senile patients with AMI.
ABSTRACT
Objective To evaluate the efficacy and safety of intravenous thrombolysis with urokinase combined with emergency interventional therapy for acute myocardial infarction(AMI). Methods Fifty two patients with first AMI (≤12 h from onset)were randomized to thrombolysis plus PCI group and primary PCI group,the patency rate of infarct related artery (IRA) before intervention,the procedural success rate,the incidence of bleeding complications and acute ischemic events during hospitalization and the left ventricular ejection fraction (LVEF) measured by echocardiography before discharge were compared.Results The IRA patency rate in the thrombolysis plus PCI group (61 5%) was significantly higher than that in the primary PCI group (19 2%) ( P 0 05),no major bleeding complication and acute ischemic event occurred during hospitalization in both groups,the LVEF in the thrombolysis plus PCI group (64 3?5 6)% was higher than that in the primary PCI group(54 8?4 9)% before discharge ( P
