The prevalence of the metabolic syndrome components and their combinations in men and women with acute ischemic syndromes
During the last decade, it has been shown that the metabolic syndrome and its different components – arterial hypertension (AH), abdominal obesity (AO), diabetes mellitus (DM), atherogenic hypertriglyceridemia (HTG), and/or low concentration of high-density lipoprotein cholesterol (HDL-C)) – increase the risk of cardiovascular diseases. There is increasing evidence that the incidence of the metabolic syndrome and the distribution of its components in combinations in the general male and female population differ. The aim of our study was to determine the incidence of the metabolic syndrome in men and women with acute ischemic syndromes and to evaluate the distribution of the metabolic syndrome component combinations in the presence of the metabolic syndrome. Contingent and methods. The study included 2756 patients (1670 males and 1086 females) with acute ischemic syndromes (1997 with myocardial infarction and 759 with unstable angina pectoris), in whom all five components of the metabolic syndrome were assessed. Women were significantly older than men (68.1±9.5 vs. 60.2±11.8 years, P<0.001). The metabolic syndrome was found (according to modified NCEP III) in 1641 (59.5%) patients (in 70.2% of females and in 52.6% of males, P<0.001). The most common components in both men and women were AH andAO(94.0%vs. 95.9%and 86.4%vs. 84.5%, respectively). HTGwas significantlymore common in men than in women (80.0% vs. 73.0%, P<0.001), while decreased HDL-C concentration was more common in women (82.8% and 59.2%, P<0.001). The DM component, detected in more than one-third of patients with acute ischemic syndromes, was significantly more common in women than in men (39.2% vs. 33.1%, P<0.05). Combinations of three components were significantly more common in men than in women, while combinations of four–five components were more common in women (55.6% vs. 41.4%, P<0.001; and 58.6% vs. 44.4%, P<0.01). The most common combination of three components in men was AH+AO+HTG and in women – AH+AO+lowHDL-C; themost common combination of four components in bothmen and women was AH+AO+HTG+low HDL-C. Conclusion. In the metabolic syndrome, the differences between the components of atherogenic dyslipidemia in patients with acute ischemic syndromes were related to the patients’ gender: men significantly more frequently had increased TG concentration and women – decreased HDLC concentration; this is the problem to be addressed in further studies of dyslipidemia
Memory of the nazi period in austria: analysis of mnemonic actors.
During the Anschluss (annexation) of Austria, the German invaders were warmly welcomed. Throughout the Nazi period, over a million Austrian men joined the German army, and Austrians played leading roles in various killing sites. Astonishingly, approximately 75% of concentration camp guards were Austrians, despite Austria's population being significantly smaller than Germany's. After the Allies occupied Austria, they divided the territory into administrative zones, similar to Germany. However, while Germany underwent a public denazification campaign, Austria's approach took a different turn. For more than four decades, Austria's public discourse and collective memory were dominated by "the Victim theory." This narrative allowed Austrians to evade moral and material responsibility for the crimes committed under Nazi rule. While the Germans were “struggling to overcome their past” (Vergangenheitsbewältigung), the Austrians were going the opposite direction. It was only in the late 1980s that a public debate emerged regarding Austria's guilt in Hitler's aggression. This thesis focuses on untangling the intricate Austrian memory field by examining it through the perspective of mnemonic actors. Its primary objective is to identify and analyze the various mnemonic actors that shaped Austria's post-war memory, as well as understand their methods of constructing and disseminating the memory of the Nazi period. To achieve this, the thesis reviews relevant literature on Austrian post-war history, collective memory, and politics of memory. It synthesizes theories of collective memory and presents a theoretical approach based on Bernhard & Kubik's interpretation of mnemonic actors and memory regimes The research then conducts an in-depth examination of the literature within three distinct timeframes to identify the mnemonic actors, which are subsequently analyzed using the discourse-historical approach The study reveals specific governmental, opposition, non-governmental, and international mnemonic actors operating within three memory regimes from 1945 to 2001. The findings highlight the different actors that influenced each regime and discuss the means through which memory was transferred. This work has made a humble attempt to contribute to the study of Austrian memory politics, with its novelty laying in the yet understudied role of mnemonic actors in Austria. There is a need to further delve into the different actors that shaped the Austrian memory field. This work has only explored one type (out of four theorized by Bernhard and Kubik) of mnemonic actors. In result, the analysis and conclusions about the type of memory regimes cannot be made
Doppler ultrasonography of the fetal tibial artery in high-risk pregnancy and its value in predicting and monitoring fetal hypoxia in IUGR fetuses
Background and Objectives: Intrauterine growth restriction (IUGR) is the term used to describe a fetus whose estimated weight is less than the 10th percentile of its age growth curve. IUGR is the second most common cause of perinatal death. In many cases there is a deficiency in the standardization of optimal management, prenatal follow-up and timing of delivery. Doppler examination is the most sensitive test that can assess the condition of the fetus and indicate fetal intrauterine hypoxia. Numerous studies of the fetal intrauterine state focus on the umbilical artery and the fetal cerebral blood vessels, while the peripheral arteries have so far received insufficient attention. Materials and Methods: We present a case of an IUGR fetus monitored with a non-stress test (NST) and a Doppler examination of the fetal arteries (tibial, umbilical, middle cerebral and uterine) and the ductus venosus. In this case the first early sign of fetal hypoxia was revealed by blood flow changes in the tibial artery. Results: We hypothesize that peripheral vascular changes (in the tibial artery) may more accurately reflect the onset of deterioration in the condition of the IUGR fetus, such that peripheral blood flow monitoring ought to be employed along with other techniques already in use. Conclusion: This paper describes the clinical presentation of an early detection of late IUGR hypoxia and claims that blood flow changes in the tibial artery signal the worsening of the fetus’s condition
Fetal biometry: Relevance in obstetrical practice
Ultrasound imaging in obstetrics and gynecology dates back to 1958 when The Lancet published the first article about the use of ultrasonography for fetal and gynecological assessments. It is now almost inconceivable, 60 years later, to think of effective performance in obstetrics and gynecology without the variety of ultrasound, for example, real time imaging, power and color Doppler, 3D/4D ultrasonography, etc. Such examinations facilitate the assessment of intrauterine fetal growth and development during pregnancy, provide alerts about the risk of pre-eclampsia and preterm birth, help identify anatomic reasons for infertility, diagnose ectopic pregnancies, uterine, ovary and tubal pathology. Ultrasonogra- phy is also used for diagnostic and treatment procedures during pregnancy or for the treatment of infertility. This article is an overview of the development of fetal ultrasound, the methodology and interpretation of ultrasound in the assessment of intrauterine fetal growth and fetal biometry standards both worldwide and in Lithuania
N-carboxymethyllysine as a biomarker for coronary artery disease and age-related macular degeneration
Background and objective: An association between coronary artery disease (CAD) and agerelated macular degeneration (ARMD) has long been postulated, but exact mechanisms remain unclear. The global prevalence of CAD and ARMD increases and early biomarkers for early diagnosis of these diseases are necessary. The aim of this study was to investigate the plasma level of oxidative stress biomarker CML in patients with and without angiographic findings of atherosclerosis in the coronary arteries (CADath+ and CADath, respectively) and to assess if there was an association of CAD with ARMD. Materials and methods: The study enrolled 233 subjects. Based on cardiologic and ophthal- mologic examinations, the patients were divided into four subgroups: CADath+ARMD+, CADath+ARMD−, CADath−ARMD+, and CADath−ARMD−. The enzyme-linked immunosorbent assay was used for the measurement of plasma CML levels. Serum lipid levels were determined by an automatic analyzer using conventional enzymatic methods. Results: CADath+ patients had higher CML concentration compared to CADath subjects (1.04 ± 0.6 vs. 0.83 ± 0.4 ng/mL, P < 0.001). The highest mean CML level (1.12 ± 0.7 ng/mL) was found in CADath+ARMD+ patients. The mean plasma CML concentration was higher in subjects with any of the analyzed diseases compared to CADath−ARMD− subjects. A significant positive association of CADath+ (OR = 2.50, 95% CI 1.60–3.90, P = 0.0001), ARMD (OR = 2.08, 95% CI 1.40–3.11, P = 0.0001) and both analyzed diseases (OR = 4.67, 95% CI 2.29– 9.53, P = 0.0001) with an increased level of plasma CML in a logistic regression model adjusting by age was identified. Conclusions: The level of CML, an oxidative stress biomarker, reflects the presence of atherosclerosis in coronary arteries and shows a possible link between ARMD and CADath+ via oxidative status
Image quality of 16-slice computed tomography coronary angiography in patients with complete left bundle branch block
Objective. Noninvasive diagnosis of coronary artery disease in patients with left bundle branch block is challenging. Multislice computed tomography can be useful in this population; however, quality of images depends on the patterns of myocardial contractions. We investigated the influence of left bundle branch block on image quality of multislice computed tomography coronary angiography. Materials and methods. Multislice computed tomography coronary angiography was performed in 30 patients with left bundle branch block and 30 patients without conduction disturbances. Image quality of each coronary segment was visually assessed and rated on a five-point scale (1=highest quality). Results. Average image quality score in the best cardiac cycle phase did not differ significantly between groups (1.71±0.59 in the left bundle branch block group vs. 1.60±0.57 in the control group, P=0.46). In the left bundle branch block group, a significantly lower image quality score was observed in end-systolic cardiac phase (2.67±0.6 vs. 2.22±0.65 in the control group, P=0.007), whereas no difference was demonstrated in mid-diastolic phase (1.73±0.6 vs. 1.69±0.66 in the control group, P=0.81). After image assessment in multiple cardiac phases, an increase in image quality score was higher in the left bundle branch block than in the control group (0.2±0.17 vs. 0.11±0.14, P=0.003). A negative correlation was observed between image quality score and both the heart rate and heart rate variability in both groups (P<0.001). Conclusion. A nonsignificantly lower overall image quality of multislice computed tomography coronary angiography was demonstrated in the left bundle branch block group. In the presence of left bundle branch block, image quality in the end-systolic phase was significantly lower. Image assessment in multiple phases increased overall image quality and is therefore advisable in patients with left bundle branch block. Increased heart rate and heart rate variability worsened image quality in both groups
Implementation of international transtelephonic ECG platform for patients with ischemic heart disease
Ischemic heart disease in European countries over decades causes up to 55% of all cases of sudden death and also has a high rate of mortality, morbidity, and hospital admission. Patients with such chronic diseases also require intensive home care facilities from community nurses. The aim was to establish international multilingual platform for transtelephonic ECG system as an alternative solution for home care and assess its performance. Methods. During this pilot study, the international toll-free line between Lithuania and Germany was established, and practical applicability of the tele-ECG device was tested. Transtelephonic ECG system was implemented between Telemedicine Center in Bad Segeberg (Bad Segeberg Clinic, Germany), the Call Center in Kaunas at the Hospital of Kaunas University of Medicine, and a patient residence. Results. Over a 6-month follow-up period, 34 patients were recruited. Following the ECG transmission, 86 teleconsultations were done. During the study, a total of 329 ECGs were sent by the patients; out of them, 14 ECGs were with clinical changes. Technical problems due to insufficient patient training, telecommunication systems, acoustic data transmission, and device itself were reported. Up to 23% of ECGs sent by patients were unreadable and not applicable for further clinical analysis. Conclusions. Our study showed the potential of telemedicine facilities to overcome the problems of access that makes the technique so potentially useful, but for telemonitoring application at patient homes in a wider population, it needs to be improved in terms of technical performance, transmission and analysis automatization
Cocaine-induced myocardial infarction (clinical case report)
Cocaine abuse has been associated with various cardiovascular complications, including angina pectoris, myocardial infarction, and sudden cardiac death. The first report of myocardial infarction temporally related to the recreational use of cocaine appeared in 1982. This article discusses the possible pathological mechanisms underlying the pathogenesis of myocardial ischemia and infarction secondary to cocaine abuse, and current ideas on the management of cocaine-induced myocardial infarction. We report a case of acute myocardial ischemia in a young healthy male patient and his 5-year follow-up
The Impact of Myocardial Revascularization After Acute Coronary Syndromes on One-Year Cardiovascular Mortality
The aim of this observational study was to evaluate the impact of myocardial revascularization performed after acute coronary syndromes on one-year cardiovascular mortality. Material and Methods. The study population comprised 1226 consecutive patients who were admitted to the Clinic of Cardiology in 2005 because of acute coronary syndromes with significant (≥70%) coronary artery stenoses. The relationship between myocardial revascularization and oneyear cardiovascular mortality was evaluated by applying multivariable logistic regression. Cardiovascular mortality was evaluated using the Kaplan-Meier method. Results. Of all the patients included into the study, 540 had Q-wave myocardial infarction, 339 patients had non–Q-wave myocardial infarction, and 347 patients were treated for unstable angina pectoris. During hospitalization, 496 patients underwent percutaneous transluminal coronary angioplasty, 373 patients underwent coronary artery bypass grafting within 60 days following acute coronary syndromes, and 357 patients received pharmacological treatment alone. During one-year follow-up, 105 cases of cardiovascular death were registered. The one-year cardiovascular mortality was significantly lower in patients who underwent percutaneous transluminal coronary angioplasty or coronary artery bypass grafting comparing with those patients who received only pharmacotherapy (5.4% and 7.8% vs. 14.3%, P<0.05). Multivariate logistic regression analysis revealed that myocardial revascularization independently reduced one-year cardiovascular mortality (adjusted odds ratio for percutaneous transluminal coronary angioplasty, 0.304; 95% CI, 0.18 to 0.53; P<0.001, and coronary artery bypass grafting, 0.540; 95% CI, 0.32 to 0.90; P=0.018) in patients who were admitted because of acute coronary syndromes. Conclusions. Myocardial revascularization performed after acute coronary syndromes was significantly associated with the reduction of cardiovascular mortality within one-year period independently of clinical variables
Cardiovascular risk in diabetes mellitus during one-year period after acute coronary syndrome
Aim. The significance of clinical characteristics during acute phase of coronary syndrome for hospital prognosis is well established. However their prognostic ability and impact on defining risk of lethal outcome during one-year period after acute coronary syndrome in pts with diabetes mellitus is not clarified. Methods. In a prospective one-year study 699 pts with first acute coronary syndrome were studied: 61 with diabetes mellitus and 638 – without diabetes mellitus. We have analyzed their demographic characteristics, risk factors of ischemic heart disease, clinical, echocardiographic, angiographic data. During one year follow up period there were 61 cases of cardiac death. Results. Univariate analysis showed, that pts with diabetes mellitus vs pts without diabetes mellitus more often were female, aged >65 years, had arterial hypertension, obesity and sinusal tachycardia, severe acute left ventricular failure, three – vessel coronary disease, episodes of paroxysmal atrial flutter during acute phase of acute coronary syndrome (p<0.05). Multivariate logistic regression analysis showed that these variables remained independent predictors for lethal outcome and had OR from 1.6 to 9.5 in pts without diabetes mellitus. The presence of diabetes mellitus increased the value of OR of these variables 1.5–2.5 fold and this followed to the further stratification of pts. The value ³14 of general risk score in multivariate model indicated the high risk for lethal outcome during one-year period. Almost half of pts (48.3%) with diabetes mellitus had the high risk, a 36.5 percent of them died during follow up. The sensitivity of risk score in predicting mortality was 37.3 percent in high risk group and 58.8 percent in low risk group, specificity – 96.7 percent and 82.7 percent respectively. Conclusion.
