易化PCI治疗心肌梗死   总被引:1,自引:0,他引:1  
急性心肌梗死(AMI)是由于病变血管内血栓形成而发生的急性闭塞,AMI的治疗从80年代的溶栓疗法,到逐渐发展起来的经皮冠状动脉介入(PCI)治疗,冠脉搭桥及干细胞移植等方案都是围绕AMI的治疗原则:尽快恢复梗死相关血管的前向血流灌注以挽救濒死心肌,防止梗死扩大及缩小心肌缺血范围,保护和维持心脏功能而展开的。但目前各种治疗方案都存在其一定的有限性。易化PCI方案是指AMI发生后首先尽可能地予以院前(或患者家中)药物溶栓再灌注疗法,同时静脉给血小板GpIIb/IIIa受体拮抗剂或口服氯吡格雷,并在这种药物易化了的再灌注治疗过程中尽快…  相似文献

OBJECTIVE: To describe factors associated with the development of stroke during long-term follow-up after acute myocardial infarction (AMI) in the LoWASA trial. PATIENTS: Patients who had been hospitalized for AMI were randomized within 42 days to receive either warfarin 1.25 mg plus aspirin 75 mg daily or aspirin 75 mg alone. DESIGN: The study was performed according to the probe design, that is open treatment and blinded end-point evaluation. SETTING: The study was performed in 31 hospitals in Sweden. The mean follow-up time was 5.0 years with a range of 1.7-6.7 years. RESULTS: In all, 3300 patients were randomized in the trial, of which 194 (5.9%) developed stroke (4.2% nonhaemorrhagic, 0.5% haemorrhagic and 1.3% uncertain. The following factors appeared as independent predictors for an increased risk of stroke: age, hazard ratio and 95% confidence interval (1.07; 1.05-1.08), a history of diabetes mellitus (2.4; 1.8-3.4), a history of stroke (2.3; 1.5-3.5), a history of hypertension (2.0; 1.5-2.7) and a history of smoking (1.5;1.1-2.0). Most of these factors were also predictors of a nonhaemorrhagic stroke whereas no predictor of haemorrhagic stroke was found. CONCLUSION: Risk indicators for stroke long-term after AMI were increasing age, a history of either diabetes mellitus, stroke, hypertension or smoking.  相似文献

Objective To study prognostic characteristics of cardiac troponin I (cTnI) elevation in acute ischemic stroke. Methods We retrospectively studied patients (n = 248) with acute ischemic stroke, acute ST-segment elevation myocardial infarction, and acute non-ST-elevation myocardial infarction who were treated between January 2013 and October 2015. Baseline demographic data and changes in cTnI levels among these three groups were compared. Patients with acute ischemic stroke were assigned to either the cTnI elevation group (cTnI > 0.034 ng/mL) or the no cTnI elevation group (cTnI ≤ 0.034 ng/mL). Logistic regression analysis was used to identify risk factors associated with elevated serum cTnI in patients with acute ischemic stroke. Moreover, the duration of hospital stay and incidence of major cardiovascular outcomes were compared in patients with acute ischemic stroke, with or without elevated cTnI. Results In this study population of patients with acute ischemic stroke (n = 178), acute ST-segment elevation myocardial infarction (n = 35), and acute non-ST-elevation myocardial infarction (n = 35), patients with acute ischemic stroke with elevated cTnI comprised 18.54% of subjects. Patients with elevated cTnI were older and more likely to have a history of hypertension. In addition, these patients had higher levels of inflammatory markers, reduced renal functions, increased D-dimer levels, higher NIH stroke scores, and lower left ventricular ejection fractions. Logistic regression analysis showed that both percentage of neutrophil and NIH stroke scores were elevated; estimated glomerular filtration rate and left ventricular ejection fraction were decreased in patients with acute ischemic stroke who had elevated cTnI, and they had more frequent major cardiovascular events during hospital stay. Conclusion Elevated cTnI detected in patients with acute ischemic stroke, indicated a greater likelihood of poor short-term prognosis during hospital stay.  相似文献

The hematopoietic and non-hematopoietic stem/progenitor cells harvested directly from the bone marrow (BM) or G-CSF mobilized peripheral blood were demonstrated to play an important role in regeneration of damaged organs (1, 2). Here, we asked if the stroke- or acute heart infarct-related stress triggers mobilization of stem/progenitor-enriched CD34(+)cells from the BM into the peripheral blood, which subsequently could contribute to regeneration of damaged tissues. To address this question the peripheral blood samples were harvested from patients with ischemic stroke during the first 24 h of manifestation of symptoms and on the second and sixth day afterwards or during the first 24 h of acute cardiac pain as well as on the second and sixth day of infarct. We measured in these patients (i) percentage of circulating hematopoietic stem/progenitor-enriched CD34(+) cells in peripheral blood by employing fluorescence activated cell sorter (FACS) and (ii) number of hematopoietic progenitor cells for the granulocyte-monocytic colony-forming unit (CFU-GM) and erythoid burst-forming unit (BFU-E) lineages circulating in peripheral blood. We concluded that stress related to ischemic stroke or acute myocardial infarction triggers the mobilization of hematopoietic stem/progenitor-enriched CD34(+) cells from the BM into peripheral blood. These circulating stem/progenitor-enriched CD34(+) cells may contribute to the regeneration of ischemic tissues, however, this possibility requires further studies.  相似文献

Viral and bacterial infections in patients with acute myocardial infarction   总被引:4,自引:0,他引:4  
The association of both viral and bacterial infections with acute myocardial infarction was investigated in a case-control study involving 40 consecutive patients with an acute myocardial infarction, 41 random controls and 30 patients with chronic coronary heart disease. All individuals were males aged 50 years or less. A rise in enterobacterial common antigen antibodies (15/40) and a recent influenza-like illness (11/40) were significantly more common among patients with acute myocardial infarction compared with the other groups. No differences were observed between the groups in the occurrence of antibodies against eight other bacterial antigens or 16 viruses.  相似文献
