The end points included patency rates on catheterization laboratory (cath lab) arrival, revascularization results when PCI was performed, complication rates, left ventricular function and restored patency rate following PCI. Results Patency on cath lab arrival was 64% with rt PA (34% TIMI 3,30% TIMI 2), while 31% of placebo (13% TIMI 3, 18% TIMI 2). There was no difference in the restored TIMI 3 rates of IRA between the two groups (85% vs 87%). No difference were observed in stroke or major bleeding. Left ventricular function was similar in both groups (52±9% vs 50±8%), but left ventricular ejection fraction fraction (LVEF) was higher with patent IRA (TIMI 3) on cath lab arrival than that of others (56±12% vs 48±10%).Conclusions Strategy thrombolytic regimens were compatible with subsequent PCI lead to more frequenc early recanalization (before cath lab arrival), which facilitates greater left ventricular function preservation with no augmentation of adverse events.展开更多

The protocols of the manipulation duration and the effect for TRA pPCI and TFA pPCI procedures were respectively compared, including the time of transradial artery puncture and the rate of puncture success at first time ; the time of guiding catheter engaging into target coronary ostium; the rate of patence in infarct related artery (IRA); total duration of manipulation and the successful rate.The incidence of complications such as bleeding, vessel injury,thrombi and embolism as well as the average stay of hospitalization between two groups was compared. The status and the incidance of vessel spasm were observed and the effect of medicine administration to prevent from and relieve the vascular spasm was evaluated. The time of Allen’s test before and after TRA pPCI , the inner diameter and the peak of blood velocity of the right and left radial artery were investigated with color Doppler vessel echography as well as the complications of radial artery were followed up 1 month after TRA pPCI procedure. Results Two cases in every TRA pPCI and TFA pPCI groups were crossed over each other because procedure of the transradial or transfemoral access was failure. One handred and six vessels (48 vessels in LAD,22 vessels in LCX and 36 vessels in RCA) associated with 28 vessels of total occlusion in TRA pPCI group and 102 vessels (51 vessels in LAD,18 veesles in LCX and 33 vessels in RCA) with 24 vessels in total occlusion in TFA pPCI group were angioplasticized . The successful rates of the first time puncture in access artery, the re patence IRA and pPCI were similar in TRA pPCI and TFA pPCI groups ( 93.4% vs 96.1% ;100% vs 100%; 96.2% vs 97.1% , P >0.05 ). There were no significant diffierence in the average time of puncture time of access artery ,engaging in target vessels of guiding catheters and the total procedure of PCI between the two groups ( 1.3 ±0.3s vs 1.2 ±0.3s ; 6.0 ±1.6min vs 5.8 ±0.9min ; 49.2 ±24.1min vs 46.5 ± 26.4min , P >0.05 ). The access artery complications such as bleeding ,hematoma and embolism as well the veneous thrombosis in TFA pPCI group were much more than those in TRA pPCI group(p< 0.01 ). Although slight artery spasm of 4.7% cases in TRA pPCI group was happened during the procedure of PCI , the procedure had being continued after administration of medicine to release the spasm. The time of Allen’s test ,diameter and the systolic velocity of blood in daul radial arteries were no significant change before and after pPCI.Conclusions The duration and effect by TRA pPCI for AMI with stable hemodynamics was similar to TFA pPCI. The complications such as of bleeding,vessel injury, thrombi and embolism by TRA pPCI were few, and it was unnecessary to discontinue the anticoagulation medicine. TRA pPCI might be selected as a access vessel for pPCI in AMI patients with stable hemodynamics.展开更多

The radio of ulnar artery versus radial artery was 1.35:1.00 and the time of Allen’s test in ulnar artery side was shorter than that in radial artery side ( 2.70 ±0.36 s vs 4.68 ±0.52s , P <0.05 ) before PCI. The efficiency of PCI TRU was evaluated. The time of manipulative duration for each procedure of PCI TRU was recorded. The time of Allen’s test, luminal diameter (mm) , cross area of vessel lumin (mm 2), blood velocity (Vs max), blood resistance (RI) in ulnar artery and radial artery and the level of blood oxygen in finger (PaO 2、SatO 2) were measured and recorded , respectively , as well were compared quantitatively before and after 1 month of procedure . Results Fourty eight lesion segments of 42 vessels in all patients were angioplasticized successfully via TRU by 6F guiding catheter including 23 segments of type B1 , 14 segments of type B2 and 11 segments of type C. PCI TRU in all of 40 patients was performed successfully. Fourty eight stents were implanted including 2 lesions of intrastent restenosis angioplasticized with cutting balloon technique before re stenting . The average time of manipulative duration of guiding catheters engaging in osicum of target coronary, crossing the vessel lesions of guidewire, dilatation and implantation of stents,and under X ray fluoroscopy were 4.30 ±0.59 min , 2.52 ±0.40min , 2.66 ±0.40 min ,and 25.9 ±0.49 min , respectively, and the total time of the whole procedure was 56.6 ±14.8 min . When the ulnar introducer was taken off, the access site in ulnar artery was suppressed by tourniquet with no bleeding in the access site and no limitation of physical activation under maintaining infusion of heparin immediately after procedure . There was no significant change in the diameter of ulnar artery and the time of Allen’s test after 1 month of PCI procedure as compared with those before procedure ( 3.22 ±0.48mm vs 3.26 ±0.22 mm , P >0.05 ; 2.96 ±0.98 s vs 2.72 ±0.47 s , P >0.05 ). No significant change was found in the parameters of blood velocity , cross area of vessel lumin, blood resistance and the level of blood oxygen in finger after 1 month of PCI procedure. The average total hospital stay was 5.21 ±0.43 days. Following up 1 month, no complications such as occlusion of ulnar artery, abnormal sensitivity and movement disability were found in right hands in all patients.Conclusions The ulnar artery might be selected as one approach of antebrachial artery for PCI in the patients with coronary heart disease whose radial artery was difficulty as access vessels of PCI, while reversed Allen’s test for radial and ulnar artery are positive and the luminal diameter of ulnar artery was larger than that of radial artery.展开更多
