Hypertension-induced subclinical vascular and cognitive changes are reversible-An observational cohort study.

Beside the well-known complications of poorly controlled, long-standing hypertension, milder abnormalities induced by early-stage hypertension have also been described. In our study, the authors examined the reversibility of changes induced by early-stage hypertension. The authors performed laboratory testing, ambulatory blood pressure monitoring, carotid intima-media thickness (IMT) measurement, evaluation of stiffness parameters, assessment of various cardiac and cerebral hemodynamic parameters during head-up tilt table (HUTT) testing, and neuropsychological examinations in 49 recently diagnosed hypertensive patients.

Altered irisin/BDNF axis parallels excessive daytime sleepiness in obstructive sleep apnea patients.

Study Objectives: Obstructive sleep apnea hypopnea syndrome (OSAHS) is a sleep-related breathing disorder, characterized by excessive daytime sleepiness (EDS), paralleled by intermittent collapse of the upper airway. EDS may be the symptom of OSAHS per se but may also be due to the alteration of central circadian regulation. Irisin is a putative myokine and has been shown to induce BDNF expression in several sites of the brain.

Plasma homocysteine levels are related to medium-term venous graft degeneration in coronary artery bypass graft patients.

Objective: Saphenous venous grafts (SVGs) are established choices for coronary artery bypass grafting (CABG); however, their lumen patency is limited. Our goal was to investigate the risk factors of SVG degeneration.

Methods: Seventy-five patients (mean age, 57.

[Myocardial infarction of rare etiology in a young adult].

Chest pain is not uncommon among young patients below the age of 35 years, however, it is rarely caused by acute coronary syndrome. The rarity of coronary artery occlusion in this population can easily lead to diagnostic mistakes. The authors present the case history of a 19-year-old young female, who was admitted to the emergency department of a local hospital due to the sudden onset of chest pain and malaise.

Elevated LDL-C combined with hypertension worsens subclinical vascular impairment and cognitive function.

Hypertension and dyslipidemia belong to the most prevalent modifiable risk factors for cerebrovascular and cardiovascular diseases. Hereby, we aimed to examine the combined effects of newly diagnosed hypertension and hyperlipidemia on the characteristics of the arterial wall and on cognitive function. We examined 72 hypertensive and 85 apparently healthy individuals.

[Short and long term prognosis of patients with myocardial infarction. Hungarian Myocardial Infarction Registry].

Introduction: Mortality data of patients with acute myocardial infarction are incomplete in Hungary.

Aim: The aim of the authors was to analyse the data of 8582 myocardial infarction patients (4981 with ST-elevation myocardial infarction) registered in the Hungarian Myocardial Infarction Register in order to define the hospital, 30-day, and 1-year mortality. To evaluate the prehospital mortality of myocardial infarction, all myocardial infarction and sudden death were registered in five districts of Budapest.

Early-phase clinical trials in the community: results from the national cancer institute community cancer centers program early-phase working group baseline assessment.

Purpose: The National Cancer Institute (NCI) Community Cancer Centers Program (NCCCP) formed an Early-Phase Working Group to facilitate site participation in early-phase (EP) trials. The Working Group conducted a baseline assessment (BA) to describe the sites' EP trial infrastructure and its association with accrual.

Methods: EP accrual and infrastructure data for the sites were obtained for July 2010-June 2011 and 2010, respectively.

Anxiety, depression and autonomic nervous system dysfunction in hypertension.

Objectives: This study examined the relationship between autonomic nervous system dysfunction, anxiety and depression in untreated hypertension.

Patients And Methods: 86 newly diagnosed hypertensive patients and 98 healthy volunteers were included in the study. The psychological parameters were assessed with Spielberger State-Trait Anxiety Inventory and Beck Depression Inventory by a skilled psychologist.

Cerebro- and cardiovascular reactivity and neuropsychological performance in hypertensive patients.

Background: Hypertensive (HT) patients are at higher risk of cognitive decline than normotensive individuals, because high blood pressure is a risk factor for mild cognitive deterioration. In this study cardio- and cerebrovascular reactivity along with cognitive performance was assessed on newly diagnosed HT patients.

Methods: Diagnosis of hypertension was based on international recommendations.

[Rectus sheath haematoma--rare complication of anticoagulant therapy].

The haematoma in the sheath of musculus rectus abdominis is a rare clinical entity. Its diagnosis is often difficult. Authors observed it in three patients who were on anticoagulant therapy.

[Complex non-invasive hemodynamic system for the evaluation of vascular status].

The vascular diseases (myocardial infarct, stroke, peripheral occlusive disease) have a common pathophysiological background, the arteriosclerosis, that impairs the autoregulation of cerebral vessels, decreases the endothelium mediated flow in the peripheral vessels. Therefore the assessment of the vascular damage or the follow-up of therapy need a complex and simultaneous approach. Currently the morphological and functional changes in the vascular system can be investigated with separated measuring systems, focusing either to cardiac or cerebral parameters (intermittent blood pressure measurement, ECG, cerebral blood flow by transcranial Doppler e.

Pharmacological mechanisms contributing to the clinical efficacy of levosimendan.

Acute decompensation of chronic heart failure is a direct life-threatening situation with short-term mortality approaching 30%. A number of maladaptive changes are amplified within the cardiovascular system during the progression of chronic heart failure that makes the decompensation phase difficult to handle. Levosimendan is a new Ca2+-sensitizer for the treatment of acutely decompensated heart failure that has proved to be effective during the decompensation of chronic heart failure and acute myocardial infarction.

[Percutaneous coronary intervention].

The aim of this article was to provide an overview on percutaneous coronary intervention and to identify the predictive factors of the outcome. Numerous and diverse factors have been associated with interventional treatment that include intrinsic stent thrombogenicity and patient-, target lesion-, and procedure-related issues. Stent design, surface coating and the addition of adjunctive pharmacotherapeutic agents may influence the degree of platelet activation.

99mTc-MIBI SPECT assessment of the effects of aneurysm resection on the left ventricular morphology.

Objective: 99mTc-MIBI SPECT is a widely used myocardial perfusion investigation technique, but few data are available concerning its use to assess the morphological characteristics of a left ventricular aneurysm (LVA) before and after LVA resection.

Methods And Results: Pre- and postoperative rest 99mTc-MIBI SPECT images were analysed in order to characterize the features of LVAs and the changes in the 3D scintigraphic parameters after apical LVA resection in 6 patients. In the middle horizontal slice an angle was defined to quantify the apical divergence associated with the LVA.

Quantitative morphological analysis of the motoneurons innervating muscles involved in tongue movements of the frog Rana esculenta.

We give an account of an effort to make quantitative morphological distinctions between motoneurons of the frog innervating functionally different groups of muscles involved in the movements of the tongue. The protractor, retractor, and inner muscles of the tongue were considered on the basis of their major action during the prey-catching behavior of the frog. Motoneurons were selectively labeled with cobalt lysin through the nerves of the individual muscles, and dendritic trees of successfully labeled neurons were reconstructed.

Disturbed regulation of cholesterol synthesis in monocytes of obese patients with hypercholesterolemia.

The aim of the present study was to clarify the influence of obesity on the functions of low-density lipoprotein receptors (LDL-R) and 3-hydroxy-3-methylglutarate-coenyzme A (HMG-CoA) reductase both in healthy control subjects and in patients with hypercholesterolemia (HC). Experiments were performed on monocytes of 15 non-obese (C I) and 11 obese (C II) healthy control subjects and on 22 non-obese (HC I) and 26 obese (HC II) patients with HC. [(125)I]LDL was used to determine LDL-R activity by measuring binding and intracellular degradation.

[Coronary angioplasty over 70 years of age].
