Objective: To evaluate the post-operative mortality of left ventricular end-diastolic pressure (LVEDP) during primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: We retrospectively analyzed 255 patients with new onset of STEMI who received primary PCI in our hospital and all patients received LVEDP measurement before coronary artery opening. According to LVEDP value, the patients were divided into 2 groups: LVEDP≤14 mmHg group,n=155 and LVEDP>14 mmHg group,n=100. The post-operative mortality up to 6 months was observed, and the effect of LVEDP on death rate was studied by Cox regression analysis. Results: Compared with LVEDP≤14 mmHg group, the patients in LVEDP>14 mmHg group had the 6 months mortality at HR=4.26, 95% CI (1.13-16.08),P=0.03. Relevant study presented that LVEDP was slightly related to LVEF (r=-0.267, P=0.001) and BNP (r=-0.154,P=0.041). Multi-regression analysis indicated that with adjusted LVEF and BNP, LVEDP was the independent predictor for post-operative mortality up to 6 months in acute STEMI patients after PCI. Conclusion: The LVEDP value measured during PCI procedure is the independent predictor for mortality after PCI in patients with new onset of STEMI.

Objective To evaluate the outcome of ST-segment elevation myocardial infarction (STEMI) patients received different reperfusion therapies. Methods The 238 consecutive STEMI patients were enrolled from February 2012 to December 2012. According to the current guideline of PCI and the choice of patients, the patients were divided into the groups of percutaneous coronary intervention (PCI), ifbrinolysis, and conservative medication. The major adverse cardiac events (MACE) was analyzed in a follow up of 6 months. Results (1) The enrolled patients included the 210 patients received PCI (88.2%), 14 patients received fibrinolysis (5.9%) and 14 patients received conservative medication (5.9%).The Median time of D2B was 110minutes.(2) The rate of late stent thrombosis was signiifcant higher in BMS than DES (n=2, 2.8%vs 0, P < 0.05) . (3) The PCI group had a signiifcantly higher incidence of stroke than the ifbrinolysis group and the conservative medication group (1.0%vs 0, P < 0.05;1.0%vs 0, P<0.05). (4) The PCI group had a signiifcantly higher incidence of bleeding compared to the thrombolysis group and the medication group (1.0% vs 0, P < 0.05; 1.0% vs 0%, P < 0.05). Conclusions The majority of STEMI patients received PCI;The D2B time, which was required<90 minutes in guideline of PCI, was found delayed in our study;Compared to ifbrinolysis and conservative medication, PCI showed better clinical outcomes of STEMI patients.
