HELD P. H.; CORBEU H. M. A.; DUNSELMAN P.; HJALMARSON A.; MURRAY D.; SWEDBER K.; FOR THE HAEMODYNAMIC STUDY GROUP OF THE METOPROLOL IN ACUTE MYOCARDIAL INFARCTION TRIAL 《European heart journal》1986,7(6):475-481
The relation of central haemodynamic changes to subsequent mortalityand peak enzyme activity was investigated in 190 patients withacute myocardial infarction. The mean delay time from onsetof symptoms to the haemodynamic study was 7.2 hours. Major exclusioncriteria were heart rate < 65beats min1, systolicblood pressure < 105 mmHg and lung rales to a distance of> 10 cm above the lung bases. Nine patients (4.7%) died within15 days and 16 patients (8.4%) within 90 days after the infarction.Compared to survivors, non-survivors were characterized by baselinedepression of cardiac index, stroke volume index and left ventricularstroke work index, while pulmonary capillary wedge pressureand peripheral resistance were increased. However, a wide overlapbetween survivors and non-survivors makes the predictive valuelow in the individual patient. Peak serum aspartate aminotransferase (S-ASAT) activity wasweakly related to baseline pulmonary capillary wedge pressure(r = 0.28; P< 0.001) and stroke volume index (r = 0.22;P7lt;0.01). The correlation to pulmonary capillary wedge pressurewas only found in anterior (r = 0.34) infarcts. Peak serum lactatedehydrogenase (LD1) was not correlated with baseline haemodynamics. 相似文献

Objectives. To investigate haemostatic markers (especially fibrinolysis), inflammatory parameters and lipids in patients with stable angina pectoris. Special attention was paid to differences between male and female patients, and to the reactivity to exercise or the diurnal variation of certain parameters.
Subjects. Eight hundred and nine patients (31% females) and a matched healthy control group ( n = 50).
Results. The patients had signs of disturbed fibrinolysis, with elevated plasma levels of tissue plasminogen activator (tPA) antigen and plasminogen activator inhibitor (PAI-1) activity at rest, and attenuated responses of tPA antigen and activity to exercise. Elevated levels of fibrinogen, white blood cell counts and orosomucoid were found, suggesting increased inflammatory activity, as well as a more disturbed lipid profile (higher triglycerides and lower HDL cholesterol levels) than among controls. Female patients had higher HDL cholesterol and lower triglyceride levels than male patients, but higher platelet counts and signs of enhanced platelet activity (β-thromboglobulin excretion). In addition, female patients had lower white blood cell counts, suggesting lesser inflammatory activity.
Conclusions. Patients with stable angina pectoris have signs of markedly disturbed fibrinolysis both at rest and in response to exercise, as well as signs of enhanced inflammatory activity and dyslipidemia. The observed sex differences suggest that male patients with stable angina pectoris may have a more lipid-related disease, whereas it may be more dependent on platelet function in females. 相似文献

Exocrine pancreatic tumours and their histological classification. A study based on 167 autopsy and 97 surgical cases 总被引:10,自引:0,他引:10
Based on histopathological examination of 264 exocrine pancreatic tumours (167 autopsy and 97 surgical) from the files of the Institute of Pathology, University of Hamburg, over a 15-yr period (1966-1980), a histogenetic classification is proposed. In addition to the more common neoplasms this also includes rarer and more recently defined entities. Of the 264 tumours, 250 were of duct origin, 10 acinar and four of uncertain histogenesis. Ductal adenocarcinoma, subdivided into a well-differentiated and a poorly-differentiated type, was most frequent (81.1%), followed by its variants: pleomorphic giant cell carcinoma 5.3%, adenosquamous carcinoma 3.8%, and mucinous carcinoma 1.1%. All these had a poor prognosis. Serous cystadenoma (1.1%), mucinous cystic tumour (1.5%) and intraductal papilloma (0.8%), which were rare tumours and mostly apparent in surgical material, proved to be benign or of only latent malignancy. The group of tumours of acinar cell origin consisted of the solid and cystic tumour (2.7%) with favourable prognosis and the acinar cell carcinoma (1.1%). No pancreatoblastoma was observed. The pleomorphic carcinomas of the small cell type (1.5%) were classed as tumours of uncertain histogenesis. 相似文献
