To assess the in-hospital clinical course and the long-term evolution of acute massive pulmonary embolism after thrombolytic therapy and to identify predictors of adverse clinical outcome Methods A total of 260 patients hospitalized from January 1989 to October 1998 were retrospectively reviewed and followed up for 3 9 to 8 4 years Baseline characteristics and variables pre- and post-thrombolysis were identified Particular attention was paid to the clinical events, including death, recurrent thromboembolism, chronic thromboembolic pulmonary hypertension, and major bleeding attributable to the use of anticoagulants Kaplan-Meier event-free survival curves were generated Univariate analysis by means of the log-rank test was used to test each candidate variable for association with clinical outcome Multivariate analysis with the Cox proportional hazard model was used to determine independent predictors of the long-term outcome Results The in-hospital mortality rate was 8 5%, with 68 2% due to pulmonary embolism itself, and the follow-up mortality rate was 31 7%, with 29 2% due to recurrent embolism Factors associated with an adverse outcome in univariate analysis were: (1) prior thromboembolic diseases; (2) duration of anticoagulant therapy 50 mmHg after thrombolysis; and (6) greater than 30% obstruction of pulmonary vasculature identified by pulmonary ventilation/perfusion scintigraphy before hospital discharge Multivariate analysis identified three independent predictors of poor long-term outcome for patients with acute massive pulmonary embolism after thrombolysis; which were: (1) Doppler recording of pulmonary artery systolic pressure >50 mm Hg, with relative risk of 3 78 and a 95% confidence interval of 2 70 to 4 86; (2)

Objective To evaluate the potential value of intravascular ultrasound(IVUS)imaging in the diagnosis of aortic intramural hematoma(AIH).Methods From September 2002 to May 2005,a consecutive series of 15 patients with suspected aortic dissection(AD)underwent both IVUS imaging and spiral computed tomography(CT).Six patients diagnosed as acute type B AIH by CT or IVUS composed the present study *** The study group consisted of five males and one female with mean age of 66 years *** of them had chest or back *** one patient,CT omitted a localized AIH and an associated penetrating atherosclerotic ulcer(PAU),which were detected by *** another patient,CT mistaken a partly thrombosed false lumen as an AIH,whereas IVUS detected a subtle intimal tear and slow moving blood in the false *** the four rest patients,both CT and IVUS made the diagnosis of AIH,however,IVUS detected three PAUs in three of them,only one of them was also detected by CT,and two of them escaped initial CT and were confirmed by follow up CT or magnetic resonance *** IVUS imaging is a safe examination and has high accuracy in the diagnosis of AIH,particularly for diagnosing localized AIH,distinguishing AIH with thrombosed classic AD and detecting accompanied small PAUs.

Background Early local platelet activation after coronary intervention identifies patients at increased risk of acute stent thrombosis （AST）. However, early changes in platelet activation in coronary circulation following drug-eluting stent （DES） implantation have never been reported. Methods In a prospective study of 26 consecutive elective stable angina patients, platelet activation was analyzed by measuring soluble glycoprotein V （sGPV） and P-selectin （CD62P） before and after implantation of either DES or bare metal stent （BMS）. All patients were pretreated with clopidogrel （300 mg loading dose） and aspirin （75 mg orally） the day before the procedure. Blood samples were drawn from the coronary ostium and 10 - 20 mm distal to the lesion site. Results Consistent with the lower baseline clinical risk, the levels of CD62P and sGPV were within normal reference range, both in the coronary ostium and distal to the lesion before percutaneous coronary intervention （PCI） procedure. The levels of CD62P and sGPV did not change significantly （CD62P：（31.1 ± 9.86） ng/ml vs （29.5 ± 9.02） ng/ml, P=0.319 and sGPV：（52.4 ± 13.5） ng/ml vs （51.8 ± 11.7） ng/ml, P=0.674, respectively） after stent implantation when compared with baseline. Changes in these platelet activation markers did not differ between stent types. Conclusions Intracoronary local platelet activation does not occur in stable angina patients before and immediately followina DES implantation when dual anti-Dlatelet is administered.

Background The value of intravascular ultrasound （IVUS） imaging in patients with replacement of the ascending aorta for acute type A aortic dissection （AD） is unknown. The purpose of this study was to assess the potential use of IVUS imaging in this setting. Methods From September 2002 to July 2005, IVUS imaging with a 9 MHz probe was performed in a series of 16 consecutive patients with suspected or established AD. This study focused on 5 of them with replacement of the ascending aorta for acute type A AD. Among these 5 patients, other imaging modalities including aortography, spiral computed tomography, magnetic resonance imaging and transesophageal echocardiography were performed in 5, 3, 3 and 1 patients, respectively. Results There were no complications related to IVUS imaging. For the replaced graft, as other imaging modalities, IVUS could identify all 5 grafts, the proximal and the distal anastomoses, and the ostia of the reimplanted coronary arteries. In 2 cases, IVUS detected 2 peri-graft pseudo-aneurysms （1 per case）, which were also detected by magnetic resonance imaging but omitted by aortography. For the residual dissection, IVUS had similar findings as other imaging modalities in detecting the patency （5/5）, the longitudinal and the circumferential extent, the thrombus （4/5）, the recurrent dissection （1/5） and an aneurysm distal to the graft （5 in 4 patients）. However, it detected more intimal tears and side branch involvements than other imaging modalities （15 vs 10 and 3 vs 1, respectively）. Conclusions In following-up patients with replacement of the ascending aorta for acute type A AD, IVUS imaging can provide complete information of the replaced graft and the residual dissection. So, IVUS imaging may be considered when the four current frequently used imaging modalities can not supply sufficient information or there are some discrepancies between them.

Objective To observe the immediate angiographic and intravascular ultrasound (IVUS) results and their effects on one month clinical outcomes in forty one patients who submitted to coronary stent deployment with IVUS guidance Methods All patients were allocated to coronary stent implantation with high inflation pressure After good angiographic results (<20% residual stenosis), all patients underwent IVUS and higher pressure dilatation would be necessary if criteria for optimal coronary stent implantation were not met The optimal criterion of IVUS for stent implantation was the ratio of intrastent lumen cross sectional area to the average of the proximal and distal reference lumen cross sectional areas ≥80% All patients had aspirin and ticlopidine therapy on the day of angioplasty and during the one month follow up period Results Optimal criteria of IVUS were obtained without any further intrastent dilatation in twenty five patients but intrastent higher pressure dilatation was performed in fourteen patients whose ultrasound results did not reach the criteria In these patients, we increased the minimal intrastent lumen area 25 7% ( P <0 05) Thirty five patients (90%) had good minimal intrastent lumen area of IVUS There were no deaths, myocardial infarction, acute stent thrombosis or need for revascularization during the study and the one month follow up Conclusions Intracoronary stent deployment under IVUS guidance, including combining aspirin and ticlopidine therapy, had beneficial ultrasound results and good clinical outcomes after one month follow up

目的探讨经皮冠状动脉介入(PCI)术中冠状动脉内血浆纤溶酶原激活剂抑制物-1(PAI-1)、D-二聚体(D-D)、凝血因子Ⅶ(FⅦa)及可溶性P选择素(CD62P)活性在球囊扩张和支架植入前后的早期改变及其与PAI-1基因多态性的相关性,评估其对急性支架血栓形成的预测价值。方法选择稳定型心绞痛患者20例,按标准方法行冠状动脉造影且证实冠状动脉狭窄均在70%以上。术中冠状动脉内血样采集顺序依次为:球囊扩张前冠状动脉入口处(Ostium)用引导导管,球囊扩张15min以后及支架植入后15min通过血栓吸引器穿过病灶在病变远端采血。结果PAI-1基因多态性在本组中分布为4G/5G型最多(12例,60%),4G/4G型其次(6例,30%),5G/5G型最少(2例,10%)。4G和5G等位基因频率分别为60%和40%。具有PAI-14G/5G基因型患者冠状动脉内血浆PAI-1、D-D以及FⅦ活性在球囊扩张后较球囊扩张前明显升高且有统计学意义(P均为0.01),然而这些指标在球囊扩张前与支架植入后比较无显著性差异。结论球囊扩张较支架植入更易损伤血管内皮并导致冠状动脉内局部、早期止血活性的一过性增高,具有PAI-14G/5G基因型患者对这种反应较为敏感。PCI术前双联抗血小板药物可以有效抑制血小板活性。
