Objective. To compare the long-term (5 year) prognostic values of commonly used risk scores on major adverse cardiovascular events (MACE) in a cohort of patients who underwent primary PCI for STEMI. Design. We created a composite endpoint of MACE, defined as the occurrence of any of the following events within 5 years: ischemic or hemorrhagic strok...

Stronger oscillations in the local Earth magnetic field may have an impact on the course of ischemic heart disease. This effect is individual for every person and depends on the sex, age, living territory, season, capability to adjust to magnetic field fluctuations and health status. Individuals who already have cardiovascular disease are more sens...

Introduction The SYNTAX score is an angiographic tool used to grade coronary artery disease (CAD) burden and complexity. SYNTAX score predicts 1-year adverse outcomes for patients with multivessel and/or left main CAD who undergo percutaneous coronary intervention (PCI). However, the relationship of the pre-PCI (basal) SYNTAX score to long-term out...

Introduction: The development of interventional cardiology increases the number of invasive procedures which are inevitably associated with increased exposure to ionizing radiation and associated risks. A percutaneous coronary intervention (PCI) substantiated by evaluation of the coronary artery lesion's functional significance is recommended by b...

Background: Geomagnetic storms strongly affect the human cardiovascular system, misbalancing adaptive mechanisms and causing severe adaptive stress responses at all levels of body regulation. Most physiological changes occur after a defined period following geomagnetic climate alterations, this ‘delay period’ lasts for 2-3 days. Methods: In total,...

Hemodialysis patients are susceptible to life-threatening arrhythmias whose incidence is markedly higher during the long interdialytic interval due to electrolyte fluctuations. Noninvasive monitoring of electrolyte fluctuations, particularly those of potassium, would enable restoring electrolyte balance before the onset of arrhythmias. This study i...

BACKGROUND: Physical activity causes a dramatic elevation in blood pressure and heart rate of individuals, usually these changes are proportional. The aim of this study was to assess the dynamic variation occurring in blood pressure and heart rate in athletes versus healthy sedentary individuals for a given amount of exercise. METHODS: A total of 1...
Article
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS). It was first described 80 years ago. Pathogenetic me­chanisms are most likely to be associated with inti­mas tear or bleeding vasa-vasorum, which resulting in intramural haemorrhage. SCAD typically occurs in young women who do not have coronary heart dis...

During past decades the science of collaboration in health care has progressed significantly worldwide, although in some regions (e.g.: Central and Eastern Europe) these processes are slower. The aim of this study was to develop a new, multidimensional measurement tool of the developing collaboration in primary health care (PHC). This study include...

Objectives: Atrial fibrillation is the most frequent cardiac arrhythmia affecting over 3 percent and appears to be increasing in general population. In addition to widely discussed such risk factor as obesity, arterial hypertension, electrolytes disbalances and dysfunction of thyroid, there is more and more evidence of human heath interactions with...

Objectives: Acute coronary syndrome as an acute oxygenated blood deprivation to the heart muscle due to atherosclerotic plaque rupture in the coronary artery followed by thrombosis is possibly associated with changes in the Earth’s local time varying magnetic field as they strongly influence hormonal and other regulatory systems’ activity. This stu...

The impact of changes in the geomagnetic field on the human body remains the subject of studies across the world, yet there is no consensus. Current studies are observing effects that require further work by researchers in order to find out the mechanisms that would allow a proper assessment of the correlations between the Earth's magnetic field va...

Background: In Lithuania, the right to confidentiality in healthcare for adolescents over the age of 16 was guaranteed in 2010 through the adoption of new legislation. This study sets out to explore changes in Lithuanian residents' attitudes towards confidentiality protection in adolescent sexual and reproductive healthcare (SRH) by comparing data...
Article
When using a reduced ECG lead system with three leads or less, the analysis of atrial activity during arrhythmias can become problematic due to low signal amplitude and noise. Long ago, Sir Thomas Lewis proposed a lead system for atrial activity enhancement in which two electrodes are placed directly on the chest, however, these leads are sensitive...
Article
Type 2 diabetes is a growing health problem globally; however, awareness about diabetes remains low. To assess the public perception of diabetes--how much does the public know about it? What are the beliefs about this challenging issue? A public opinion survey was performed in April 2012. Interviews with a random sample of 1,002 residents of Lithua...

A large unmet need for mental healthcare in Lithuania is partially attributable to a lack of primary care providers with skills in this area. The aim of this study was to assess general practitioners' (GPs) experience in mental healthcare and their perceptions about how to increase their involvement in the field. In this cross-sectional study, a 41...

A team approach in primary care has proven benefits in achieving better outcomes, reducing health care costs, satisfying patient needs, ensuring continuity of care, increasing job satisfaction among health providers and using human health care resources more efficiently. However, some research indicates constraints in collaboration within primary h...

Introduction General practitioners (GPs) write about 80% of all antibiotic prescriptions, the greatest number of them for patients with respiratory tract infections. However, there is a lack of research targeting the influence of external factors on antibiotic prescribing by physicians. This study aimed to explore experiences of GPs in Lithuania an...

Heart rate variability reflects current functional state of organism, the activity of autonomic nervous system and individual's adaptive reserves in response to changes in external or internal body functioning conditions. The aim of this study is to evaluate regulatory changes of autonomous cardiac function on systemic level (RR variability), arisi...
Article
Background. General practitioners (GPs) often become the first point of care for mental health issues. Improved collaboration between GPs and mental health teams can make a GP's mental health services more efficient. Objective. The aim of this study was to assess the collaboration between GPs and mental health team members and determine predictors...

Noninvasive risk stratification of patients who have suffered myocardial infarction (MI) is one of the greatest challenges in today's cardiology. No single test has sufficient predictive ability. Therefore, a combination of the tests must be applied for better post-MI risk stratification. The purpose of this study was to assess noninvasive predicto...

The long JTC interval of ECG can cause the life threatening arrhythmic events and is a non-questionable factor of sudden death. According to some authors, the JT interval gets shorter during 4-6 hours after percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction (AMI). The aim of this study was to determine the influenc...
