Clinical analysis of the early prognosis of the different ZEEK thrombus aspiration catheter application methods in acute ST-segment elevation myocardial infarction patients / 中国医师进修杂志

Objective To observe the ZEEK thrombus aspiration catheter use on the level of vascular and myocardial perfusion in acute ST-segment elevation myocardial infarction (STEMI) patients,as well as the impact of early prognosis in order to clear the relative best use of ZEEK thrombus aspiration catheter.Methods Eighty-eight acute STEMI patients who underwent percutaneous coronary intervention (PCI),according to the direct use of ZEEK thrombus aspiration catheter or after pre-expansion with small balloon,divided into direct aspiration group 45 cases,and inflation pre-aspiration group 43 cases.All patients underwent stenting,observed the perfusion of the vascular and myocardial levels after stenting,after 1 month,determined N end of B type natriuretic peptide (NT-proBNP) level,observed segmental wall motion score index (WMSI) and left ventricular ejection fractions (LVEF).Results Direct aspiration group was significantly better than inflation pre-aspiration group in the TIMI frames count,rate of TIMI coronary myocardial perfusion grade 2-3 grade and after 2 h ST segment resolution ＞ 50％ rate [(31.3 ± 7.9) frames vs.(42.5 ± 8.5) frames,84.4％(38/45) vs.72.1％(31/43),86.7％(39/45) vs.74.4％(32/43),P＜0.01 or ＜ 0.05].After 1 month,direct aspiration group was significantly lower than inflation pre-aspiration group in the peak of creatine kinase isozyme MB,NT-proBNP and WMSI [(2141.3 ± 306.5)U/L vs.(2734.5 ± 366.1)U/L,(443.2 ± 226.4) ng/L vs.(512.9 ± 281.7) nig/L,1.32 ± 0.16 vs.1.59 ± 0.23,P ＜ 0.05],but there was no significant difference in LVEF between two groups (P ＞ 0.05).Conclusions Repeated aspiration to infarction responsibility lesion segments using ZEEK thrombus aspiration catheter,and direct stenting,which is superior to the thrombus aspiration and stenting placement after single or multiple pre-expansion.

Analysis of Acute Myocardial Infarction Caused by Aortic Value Imcompentence / 中国医师杂志

Objective To Discuss the Clinical Recognition of Acute Myocardial Infarction(AMI) caused by aortic valve incompetence.Methods Data of 275 AMI patients in our hospital recent two years,7 of them were caused by aortic valve incompetence; all of patients(7 AMI) were received coronary artery angioplasty,ultrasound,left ventricular angiography examination,its clinical feature was analyzed.Results All of 7AMI patients have normal coronary without limited constriction or plaque and with aortic valve incompetence.
