Impact of prehospital delay on mortality in patients with acute myocardial infarction treated with primary angioplasty and intravenous thrombolysis.
2001
Abstract Background In patients with acute myocardial infarction treated with thrombolysis, longer times to treatment are associated with increasingly worse clinical outcome. This relation may be different for treatment with primary angioplasty. Methods We analyzed the pooled data of the German acute myocardial infarction registries Maximal Individual Therapy in Acute Myocardial Infarction (MITRA) and Myocardial Infarction Registry (MIR) to determine the influence of prehospital delays on hospital mortality rates. Primary angioplasty was performed in 1063 patients and thrombolysis in 7552 patients. Results In patients treated with thrombolysis, in-hospital time to treatment was constantly 3…
Postoperative Reduction of Fibrinolysis as a Prognostic Factor of Fatal Outcome
2001
For the resection of an esophagus carcinoma a mortality rate of 2 to 30% was described, It is still unclear whether an abdominothoracic or transhiatal intervention is superior regarding the outcome. To investigate the prognostic value of fibrinolytic markers, plasmin-α2-antiplasmin (PAP) and D-dimer (DD) values were determined daily in the early postoperative period for 11days. In addition, the course of PAP and DD concentrations was compared with the method of esophagectomy. Of the 28 patients enclosed in the study, 5 died between day 10 and day 34 owing to adult respiratory distress syndrome and septicemia. The PAP and DD concentrations increased in survivors after surgery until day 5 an…
Five-Year Survival in Patients With ST-Segment–Elevation Myocardial Infarction According to Modalities of Reperfusion Therapy
2014
Background— Although primary percutaneous coronary intervention (pPCI) is the preferred reperfusion method for ST-segment–elevation myocardial infarction, it remains difficult to implement in many areas, and fibrinolytic therapy is still widely used. Methods and Results— We assessed 5-year mortality in patients with ST-segment–elevation myocardial infarction from the French Registry of Acute ST-Elevation or Non-ST Elevation Myocardial Infarction (FAST-MI) 2005 according to use and type of reperfusion therapy. Of 1492 patients with ST-segment–elevation myocardial infarction with a first call ≤12 hours from onset, 447 (30%) received fibrinolysis (66% prehospital; 97% with subsequent angiogra…
Endovascular management of the deep venous thrombosis: A new challenging role for the endovascular specialist in 2020
2020
Over the last years, the endovascular approach to the management of the acute and chronic deep vein thrombosis (DVT) has gained more and more attention from the scientific community. DVT is the third most common cardiovascular disease after coronary heart disease and stroke, with classic treatment based on anticoagulation. Recent evidences have highlighted the risk of postthrombotic syndrome as high as 30%-50% in proximal ilio-femoral lesions, with irreversible clinical symptoms and impact on the quality of life of the population. Since 2000s, the new concept of thrombus removal in the acute phase has been supported by the introduction of different techniques based on the endovascular ablat…
Plasma levels of inflammatory and thrombotic/fibrinolytic markers in acute ischemic strokes: Relationship with TOAST subtype, outcome and infarct site
2009
BACKGROUND: The aim of our study was to evaluate in patients with acute ischemic stroke the relationship between immuno-inflammatory variables, clinical outcome and infarct site. MATERIALS AND METHODS: We evaluated plasma levels of IL-1beta, TNF-alpha, IL-6 and IL-10, E-selectin, P-selectin, sICAM-1 ,sVCAM-1 vWF, TPA and PAI-1. RESULTS: Patients with cardioembolic subtype showed significantly higher median plasma levels of TNF-alpha, IL-6, IL-1beta whereas the lacunar subtype showed significantly lower median plasma levels of TNF-alpha, IL-6 and IL-1beta. CONCLUSIONS: A significant association was noted between the severity of neurological deficit at admission, the diagnostic subtype and so…
The importance of diagnosing the Polycystic Ovary Syndrome
2000
The polycystic ovary syndrome (PCOS) is an extremely common disorder that occurs in 4% to 7% of women of reproductive age. Although PCOS is known to be associated with reproductive morbidity and increased risk for endometrial cancer, diagnosis is especially important because PCOS is now thought to increase metabolic and cardiovascular risks. These risks are strongly linked to insulin resistance and are compounded by the common occurrence of obesity, although insulin resistance and its associated risks are also present in nonobese women with PCOS. Women with PCOS are at increased risk for impaired glucose tolerance, type 2 diabetes mellitus, and hypertension. Cardiovascular disease is believ…
ABNORMALLY HIGH THROMBOXANE BIOSYNTHESIS IN HOMOZYGOUS HOMOCYSTINURIA. EVIDENCE FOR PLATELET INVOLVEMENT AND PROBUCOL-SENSITIVE MECHANISM.
1993
Homocystinuria due to homozygous cystathionine beta-synthase deficiency is an inborn error of metabolism characterized by a high incidence of thrombosis and premature atherosclerosis. We evaluated TXA2 biosynthesis in vivo and several in vitro tests of platelet function in 11 homocystinuric patients and 12 healthy controls. In vitro, patients' platelet aggregation was within control values as were TXB2 formation, fibrinogen binding, and ATP secretion in response to thrombin. In contrast, the urinary excretion of 11-dehydro-TXB2, a major enzymatic derivative of TXA2, was > 2 SD of controls in all patients (1,724 +/- 828 pg/mg creatinine, mean +/- SD, in patients vs. 345 +/- 136 in controls, …
Murine tissue factor disulfide mutation causes a bleeding phenotype with sex specific organ pathology and lethality.
2019
Tissue factor is highly expressed in sub-endothelial tissue. The extracellular allosteric disulfide bond Cys186-Cys209 of human tissue factor shows high evolutionary conservation and in vitro evidence suggests that it significantly contributes to tissue factor procoagulant activity. To investigate the role of this allosteric disulfide bond in vivo, we generated a C213G mutant tissue factor mouse by replacing Cys213 of the corresponding disulfide Cys190-Cys213 in murine tissue factor. A bleeding phenotype was prominent in homozygous C213G tissue factor mice. Pre-natal lethality of 1/3rd of homozygous offspring was observed between E9.5 and E14.5 associated with placental hemorrhages. After b…
Improvement of fibrinolysis and plasma lipoprotein levels induced by gemfibrozil in hypertriglyceridemia.
1995
A randomized double-blind study was carried out with gemfibrozil (600 mg b.i.d.) vs placebo in 20 patients (twelve males and eight females, age 52 +/- 3 years, BMI 24.2 +/- 0.4) suffering from primary hypertriglyceridemia (Fredrickson's type IV). Each group was treated for a 12 week period with gemfibrozil (n = 10) or placebo (n = 10) patients) in a double-blind fashion. Total cholesterol, HDL-cholesterol (HDL-C) and its subfractions (HDL2-C and HDL3-C), blood glucose, Apolipoproteins A1 and B, fibrinogen, plasminogen, factor VII, t-PA:Ag and PAI activity pre- and post-venous occlusion (VO) were determined. In the gemfibrozil-treated group a significant decrease of total cholesterol and tri…
Use of Thromboelastography in severe sepsis a case-control Study
2011
Thromboelastography (TEG) is a global test of coagulation that records the viscoelastic changes in blood during clot formation. Cardiosurgery and liver transplantation are established fields of application for TEG. Severe sepsis is often characterized by an imbalance of the haemostatic equilibrium between clot formation and fibrinolysis in favor of a procoagulant status, especially in the first phase. A hypocoagulant status due to coagulation factor consumption could occur later. In spite of this, the correlation between TEG and sepsis is not clearly established. Moreover, there are doubts about which TEG-detected variable is best correlated with sepsis. The aim of this study is to clarify …
