Its occurrence has been substantially reduced by thienopyridine treatment. However, information on clinical profile of patients with SAST in clopidogrel era is limited. In order to define the incidence and factors predisposing to stent thrombosis, we analyzed the computerized angiographic database of three interventional cardiology centers. Out of a total number of 5903 percutaneous coronary interventions (PCIs) with stent implantation, we found 10 patients with SAST (0.17%). The indication for PCI was usually an early invasive approach (90%) during an acute coronary syndrome. All patients were treated with an apparently optimal antithrombotic regimen (90% received heparin or LMWH and 70% received IIb/IIIa receptor inhibitors and all given aspirin). In each of the patients, we could identify high-risk angiographic findings. SAST presentation was always clinically significant with definite myocardial infarction in 100% of cases. 80% of cases occurred during the first six days post PCI. Two patients had a recurrent event. Finally, despite earlier reports of atorvastatin-mediated inhibition of clopidogrel activation we did not find any patient with SAST taking both drugs. Thus, patients with stent thrombosis during thienopyridine treatment usually exhibit high-risk angiographic features. Prospective studies should be performed to elucidate drug interactions that may reduce clopidogrel efficacy and contribute to stent thrombosis.","PeriodicalId":83747,"journal":{"name":"International journal of cardiovascular interventions","volume":"6 3-4","pages":"160-4"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628840310030478","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25289456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heparin-coated stent (HCS) may improve procedural outcomes when treating these high-risk lesions. The purpose of this study was to determine the safety and efficacy of HCS in patients with acute coronary syndromes and thrombus containing lesions.Methods: Between January 2001 and January 2002, 49 patients (42 male) with thrombus containing lesions (32 sustained acute myocardial infarction) received HC BX stents (HepaCoat) at our hospital. Procedural, hospital and six-month outcomes and quantitative angiographic analysis data were obtained from all patients.Results: The mean age of patients was 58 +/- 14 years, 45% had multi-vessel disease and 24% were diabetics. Fifteen patients (31%) received a second HCS for sub-optimal results or threatened closure. Procedural success was achieved in 94% of patients. The mean stent diameter and length was 3.2 +/- 0.2 mm and 18.2 +/- 7.4 mm. The mean TIMI flow increased from 1.3 +/- 1.3 to 2.9 +/- 0.3 and the mean diameter stenosis before and after intervention was 84 +/- 21% and 12 +/- 14%. In-hospital and 30-day follow-up were eventually without occurrence of death, myocardial infarction, stent thrombosis, coronary bypass. At six-months follow-up, cardiac event-free survival was 89.8%, target vessel revascularization was 6.1 and 90% of patients were free of angina.Conclusion: In this series of patients with acute ischemic syndromes associated with visible thrombus, the use of HCS resulted in (1) favorable procedural and six-month outcomes, (2) no incidence of stent thrombosis, and (3) overall good cardiac prognosis at six-month follow-up.","PeriodicalId":83747,"journal":{"name":"International journal of cardiovascular interventions","volume":"6 2","pages":"77-81"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628840410034762","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24698337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Euro-SPAH is a multi-center, double blind, randomized trial investigating the efficacy of IST to reduce in-stent late loss.Methods: Patients with angina or silent ischaemia with stented de novo lesions were randomised to sham or IST. The sample size had a 90% power to detect a late loss difference of 0.21 mm at 6 months. The secondary endpoints were MACE at 1, 6, 12 months and neo-intimal hyperplasia on IVUS at 6 months.Results: At 23 sites in Europe, 403 patients were randomized, with successful treatment with sham or IST in 95.6%. There were no significant differences between the groups in terms of baseline demographics or lesion characteristics. Angiographic follow-up was obtained in 89%. In-stent late loss was not significantly different. The restenosis rate at 6 months was 23% in the IST group versus 25% in the sham group. The IVUS measurements confirm the absence of effect of IST on neointimal hyperplasia. At one year, the event-free survival did not significantly differ between the two groups.Conclusion: The use of sonotherapy following stent implantation in de novo lesions does not reduce intra-stent neointimal hyperplasia, or effect the angiographic restenosis rate compared to sham treatment.","PeriodicalId":83747,"journal":{"name":"International journal of cardiovascular interventions","volume":"6 2","pages":"53-60"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628840410030405","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24697895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Self-expanding (SE) stents generate a lasting force on the arterial wall and may lead to an increased arterial response with time.Objectives: To characterize the process of neovascularization with SE stents, and to correlate it with vascular injury, inflammation and intimal proliferation.Methods: Sixty-nine SE stents were im-planted in 37 non-atherosclerotic pigs.Detailed, multisection histological examination was performed at 15 days, 1, 3 and 6 months post-deployment. Neo-vascularization in addition to other histologic parameters where determined and scored.Results: Intravascular-ultrasound-based average vessel diameter was 3.3 +/- 0.04 mm; stent size was 3.75 +/- 0.35 mm leading to an oversizing ratio of 1.14 +/- 0.15. Intimal thickness (IT), inflammatory score (IFS) and vascularization score(VAS) reached peak values at three months (IT = 344 +/- 202 1m, IFS = 0.91 +/- 0.5, and VAS = 1.56 +/- 0.8). In contrast,the injury score (INS) continued to increase at all time-points, with maximum value at six months (INS = 1.6 +/- 0.7). Both vascularization and inflammation indices increased with an increase in the injury score (p < 0.01). When vessels were divided according to vascularization score (VAS <1.5 and >1.5) there was a significant difference in IT.Conclusion: Neovascularization in response to SE stents is a time-dependent phenomenon and interacts with injury and inflammation. The remodeling of the vessel wall caused by the sustained force of the SE stent on the arterial wall enhances the formation of neovascularization. Neointimal formation is related to the degree of neovascularization.","PeriodicalId":83747,"journal":{"name":"International journal of cardiovascular interventions","volume":" ","pages":"61-7"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628840310022117-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40919060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
