Oxidative Stress Markers and Their Dynamic Changes in Patients after Acute Ischemic Stroke.

We have focused on determining the range of oxidative stress biomarkers and their dynamic changes in patients at different time points after the acute ischemic stroke (AIS). 82 patients with AIS were involved in our study and were tested: within 24 h from the onset of the attack (group A); at 7-day follow-up (group B); and at 3-month follow-up (group C). 81 gender and age matched volunteers were used as controls. Stroke patients in group A had significantly higher concentrations of plasma lipid peroxides and urine 8-isoprostanes when compared with controls. Protein carbonyls were not significantly different in any experimental group compared to controls. Antioxidant capacity of plasma was increased only in experimental group C. Activities of superoxide dismutase and catalase were elevated in all three experimental AIS groups compared to controls. Paraoxonase activity was reduced in groups A and B and unchanged in group C when compared to controls. Glutathione peroxide activity was elevated only in group A. Our results suggest that free radical damage is the highest within 24 h after the attack. During the next 3 months oxidative damage to lipids caused by free radicals is reduced due to activated antioxidant system.

AIM: The aim of this review is to address documents and a number of studies on hypertension published in the last years in order to assess their contribution to our expanding knowledge of arterial hypertension. DISCUSSION: Arterial hypertension is not defined by symptoms and signs but by numbers of blood pressure values. Arterial hypertension is vascular disease (vascular risk factor) of many vascular diseases (atherosclerosis; arteriolosclerosis/arteriolonecrosis/arteriolocalcinosis; arterial thrombosis; arterial embolism; arterial thromboembolism; arterial dissection; complicated arterial aneurysm) and other. CONCLUSION: Arterial hypertension is cause and consequence of functional (endothelial dysfunction) and of structural organovascular injury (multiorganomultivascular disease). Blood vessels are culprits, implements and victims of arterial hypertension and of organovascular arterial diseases.

[Uncorrected Tetralogy of Fallot--a case report of a 69-year-old patient]. / Nekorigovaná Fallotova tetralógia u 69-rocného pacienta.

Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart defect. The actual treatment relies on cardio-surgery--complete correction within the infant age. Without surgery only 10% of subjects survived 3rd decade and only 3-5% of subjects were able to survive until their 40th. This particular paper is dedicated to case of a 69-years old male subject with positive history of uncorrected ToF due to his refusal of surgery, ischemic cardiac disease NYHA III-IV and chronic kidney failure. This subject was hospitalized within the department of internal medicine due to several days of chest pain connected with lower extremities oedemas and dyspnoeic syndrome after minimal physical load. Provided echocardiography revealed pulmonary artery stenosis, severe tricuspid insufficiency, concentric hypertrophy of ventricles, ventricular septal defect, dextroposition of aorta and severe pericardial effusion. Chest X-ray proved massive pleura effussion. The actual conditions of subject improved significantly after onset of diuretics, antiarrhytmics and providing of pleural punction. Subject has been discharged. Cases of ToF presented within available sources in older population were associated with left ventricular hypertrophy and hypoplastic pulmonary artery and slow subpulmonal obstruction development which also presented within our subject. Left ventricular hypertrophy has a potential to develop continuously and therefore its benefits can be visible within adult age.
