Also the application of thrombolytic agent inside of coronary artery,platelet inhibitors GP Ⅱ/Ⅲ or direct thrombectomy can't improve short or long-term clinical outcomes, So we evaluated the safety and efficacy of distal protection device (GuardWire PlusTM) in the acute myocardial in farction (AMI) combined with percutaneous coronary intervention (PCI). Method Seventy-two patients with acute myocardial infarction receiving emergency PCI were randomly assigned into the distal protection group (GW group) and non-distal protection group(NGW) group. Data analyzed between the two groups were included the clinical characteristics, angiographic results, ST segment resolution, postoperative TIMI flow grade, TIMI frame count, myocardial blush grade, the left ventricular ejection fraction (LVEF) by eehocardiography in a Week after or 3 months after PCI, myocardial enzymes,preoperative and postoperative neuroendoerine biomarkers: endothelin (ET), plasma renin activity (PRA), angiotensin Ⅱ (AII), aldosterone(ALD), norepinephrine(NE), epinephrine (E). Results ST segment resolution ≥ 50% was significantly higher in the GW group (68.4%) than in NGW group (41.2%, P 〈 0.05). Early peak CK-MB and CTNI in GW group versus NGW group (8.63 ±2.42 hours vs 11.18 ±2.26 hours,10.16 ±2.96 hours vs 12.35 ±2.06 hours), and peak reduction difference were observed (63.3 ±9.82 vs 74.28 + 6.15 P = 0.000, 18.01 + 7.21 vs 21.48 ±5.61 P = 0.027). Left ventricular ejection fraction (LVEF) was higher in GW group (P = 0.01) than in NGW group. TIMI grade exhibited no difference while TIMI frame count (P = 0.043) and myocardial blush grade were significantly different (P = 0.0001). Postoperative biomarkers in endocrine expression were higher significantly in NGR group (P 〈 0.05). Conclusions Emergency PCI combined with distal protection device can help prevent distal embolism, reduce the risk of no-reflow and slow flow and thereafter improve the prognosis in AMI patients.展开更多

Although intra-aortic balloon pumping (IABP) is sometimes used in such patients to increase the diastolic coronary blood flow, there is little available information regarding the effects of IABP on the angiographic no-reflow phenomenon. Method Twenty-two AMI patient with NR were performed primary PCI between January 2006 and December 2009, of which 12 patients were selected for IABP therapy and the left 10 were selected as the control group by group procedure of odd and even days; We observed the vasoactive substance in both groups on the days of 1, 2, 3, 5, 7, 10 after the different interventions, which include plasma renin activity (PRA), angiotensin Ⅱ (ANG Ⅱ), aldosterone (ALD), adrenaline (E), and noradrenalin (NE); In addition, cardiac structure and cardiac ventricle systolic function including left atrium medial diameter (LAMD), left ventricular medial diameter (LVMD) Finally, left ventricular ejection fraction (LVEF) were evaluated after 10 days, 3 months and 6 months; statistics was taken to analysis. Results According to the time concentration curve, vasoactive substance of the IABP group decreased faster than that of the control group, and this difference had statistical significance (P 〈 0.01 ) ; In terms of LAMD, LVMD, and LVEF, echocardiography difference of the IABP and the control group in 10 days, 3 months, and 6 months also showed statistical significance (P 〈 0.05). Conclusions IABP can significantly reduce the release of vasoactive substances of NR in patients of primary PCI for AMI; LAMD, LVMD and LVEF in 10 days, 3 months, and 6 months can be improved using this method, which is conducive to recovery of heart function.展开更多
