Blood pressure measurement and assessment of arterial structure and function: an expert group position paper.

Measuring blood pressure (BP) and investigating arterial hemodynamics are essential in understanding cardiovascular disease and assessing cardiovascular risk. Several methods are used to measure BP in the doctor's office, at home, or over 24 h under ambulatory conditions. Similarly, several noninvasive methods have been introduced for assessing arterial structure and function; these methods differ for the large arteries, the small ones, and the capillaries. Consequently, when studying arterial hemodynamics, the clinician is faced with a multitude of assessment methods whose technical details, advantages, and limitations are sometimes unclear. Moreover, the conditions and procedures for their optimal implementation, and/or the reference normality values for the parameters they yield are not always taken into sufficient consideration. Therefore, a practice guideline summarizing the main methods and their use in clinical practice is needed. This expert group position paper was developed by an international group of scientists after a two-day meeting during which each of the most used methods and techniques for blood pressure measurement and arterial function and structure evaluation were presented and discussed, focusing on their advantages, limitations, indications, normal values, and their pragmatic clinical application.

Does atrial fibrillation still increase the risk of death? One-year follow-up results of the NOMED-AF study.

INTRODUCTION: Although atrial fibrillation (AF) is a well­known risk factor for ischemic stroke and hospitalization, its effect on mortality has not been clearly established. OBJECTIVES: We aimed to assess whether AF is an independent risk factor for death. A secondary objective was to evaluate the role of oral anticoagulation in the prevention of stroke and death in 1­year follow­up of patients included in the NOMED­AF (Noninvasive Monitoring for Early Detection of Atrial Fibrillation) study. PATIENTS AND METHODS: The NOMED­AF study included 3014 patients. The participants underwent continuous long­term electrocardiographic monitoring using a wearable vest for up to 30 days. The present analysis involved 2795 patients who completed the 1­year follow­up. The median (interquartile range) follow­up time was 365 (365-365) days. AF was diagnosed in 617 participants. RESULTS: Independent risk factors for death in the patients who completed the 1­year follow­up were AF, age equal to or above 65 years, and chronic kidney disease. The individuals with diagnosed AF had an almost 2­fold higher risk of death (odds ratio [OR], 1.7; 95% CI, 1.18-2.44; P <0.001) and a 2.5­fold higher risk of stroke (OR, 2.53; 95% CI, 1.41-4.44; P <0.001), as compared with those without an AF diagnosis. The participants with AF who received oral anticoagulants had an almost 5­fold lower risk of death than those who were not on anticoagulation (2.9% vs 14.2%, respectively; P <0.001). CONCLUSIONS: AF is an independent risk factor for death and cardiovascular hospitalization. The risk of death and stroke in patients with AF is significantly higher than in the patients without this arrhythmia. Oral anticoagulation in patients with AF significantly reduces the rates of death and stroke; however, its use is suboptimal in this group of patients.

Serial echocardiographic evaluation of COVID-19 patients without prior history of structural heart disease: a 1-year follow-up CRACoV-HHS study.

Background: It is a well-known fact that COVID-19 affects the cardiovascular system by exacerbating heart failure in patients with preexisting conditions. However, there is a poor insight into the cardiovascular involvement and sequelae in patients without preexisting conditions. The aim of the study is to analyse the influence of COVID-19 on cardiac performance in patients without prior history of structural heart disease. The study is part of the CRACoV project, which includes a prospective design and a 12-month follow-up period. Material and methods: The study included 229 patients hospitalised with a diagnosis of COVID-19 (median age of 59 years, 81 were women). A standard clinical assessment and laboratory tests were performed in all participants. An extended echocardiographic image acquisition was performed at baseline and at a 3-, 6-, and 12-month follow-up. All analyses were performed off-line. A series of echocardiographic parameters was compared using repeated measures or Friedman analysis of variance. Results: In all subjects, the left ventricular (LV) ejection fraction at baseline was preserved [63.0%; Q1:Q3 (60.0-66.0)]. Elevated levels of high-sensitivity cardiac troponin T were detected in 21.3% of the patients, and elevated NT-proBNP levels were detected in 55.8%. At the 1-year follow-up, no significant changes were observed in the LV diameter and volume (LV 48.0 ± 5.2 vs. 47.8 ± 4.8 mm, p = 0.08), while a significant improvement of the parameters in the biventricular strain was observed (LV -19.1 ± 3.3% vs. -19.7 ± 2.5%, p = 0.01, and right ventricular -19.9 ± 4.5% vs. -23.2 ± 4.9%, p = 0.002). In addition, a decrease in the LV wall thickness was also observed (interventricular septum 10.4 ± 1.6 vs. 9.7 ± 2.0 mm, p < 0.001; LV posterior wall 9.8 ± 1.4 vs. 9.1 ± 1.5 mm, p < 0.001). Conclusions: In an acute phase of COVID-19, the elevation of cardiac biomarkers in patients with normal left ventricular ejection fraction is a frequent occurrence; however, it does not translate into clinically significant cardiac dysfunction after 1 year. The serial echocardiographic evaluations conducted in patients without preexisting structural heart disease demonstrate an overall trend towards an improved cardiac function and a reduced myocardial thickening at 1-year follow-up. This suggests that the acute cardiac consequences of COVID-19 are associated with systemic inflammation and haemodynamic stress in patients without preexisting conditions.

The effectiveness of atrial fibrillation identification using noninvasive long-term electrocardiographic monitoring system (NOMED-AF TECH).

INTRODUCTION: Although it is well­known that longer electrocardiographic (ECG) monitoring allows for detection of paroxysmal silent atrial fibrillation (SAF), it is still unknown how long the ECG monitoring should last to increase the probability of SAF diagnosis. OBJECTIVES: Our aim was to analyze ECG acquisition parameters and timing to detect SAF during the Noninvasive Monitoring for Early Detection of Atrial Fibrillation study. PATIENTS AND METHODS: The protocol assumed up to 30 days of ECG telemonitoring of each participant in order to reveal AF / atrial flutter (AFL) episodes lasting at least 30 seconds. SAF was defined as AF detected and confirmed by cardiologists in asymptomatic individuals. The ECG signal analysis was based on the results of 2974 participants (98.67%). AF/AFL episodes were registered and confirmed by cardiologists in 515 individuals, that is, 75.7% of all patients (n = 680) in whom AF/AFL diagnosis was established. RESULTS: The median monitoring time to detect the first SAF episode was 6 days (interquartile range [IQR], 1-13). Fifty percent of the patients with this type of arrhythmia were identified by 6th day (IQR, 1-13) of the monitoring, and 75% by the 13th day of the study. Paroxysmal AF was registered on average on 4th day (IQR, 1-10). CONCLUSIONS: The ECG monitoring time to detect the first episode of SAF in at least 75% of patients at risk of this arrhythmia was 14 days. Detection of 1 patient with de novo AF, SAF, or de novo SAF, required monitoring of, respectively, 17, 11, and 23 patients.

Prevalence and factors predisposing to potential drug-drug interactions in a Polish community-dwelling geriatric population: An observational, cross-sectional study.

BACKGROUND: Due to advanced age, multimorbidity and polypharmacotherapy, older patients are predisposed to drug interactions and the adverse effects of inappropriate drug combinations. OBJECTIVES: To provide up-to-date data on predisposing factors and the prevalence of possible drug interactions in the Polish geriatric population and to promote automated analysis programs as part of safe pharmacotherapy. MATERIAL AND METHODS: We used the Lexicomp® Drug Interactions database to assess pharmacological interactions between active substances included in all types of preparations (prescription drugs, over-the-counter drugs, vitamins, nutritional preparations, and dietary supplements) used at least once in the 2 weeks preceding the study, among 2633 home-dwelling people aged >65 years. The variables measured included age, sex, place of residence, level of education, and multimorbidity. Post-stratification was used to weigh the sample structure against the Polish population in 2017. RESULTS: Drug interactions were identified in 81.2% of all individuals. The mean number (with 95% confidence interval (95% CI)) of all drug interactions was 4.24 (4.02-4.46), and the median value (with 1st and 3rd quartiles (Q1-Q3)) was 3 (1-6). At least 1 category C interaction was observed in 75.8% of all study participants, 24.3% had 1 or more category D interaction, and 4.3% had 1 or more category X interaction. The most important predisposing factor to drug interactions was multimorbidity. CONCLUSIONS: This study identified a high prevalence of potential drug interactions in the Polish geriatric population. Automated analysis systems deliver useful information on pharmacological interactions and should be promoted in the Polish healthcare community as tools to support pharmacotherapy.

Polypharmacy among elderly patients in Poland: prevalence, predisposing factors, and management strategies.

INTRODUCTION: The world's elderly population is growing dramatically. Pharmacotherapy in seniors is particularly challenging due to changes in metabolism, multimorbidity, and a great interest in nonprescription drugs. OBJECTIVES: We aimed to provide up­to­datedata on pharmacotherapy in the geriatric population of Poland, to determine factors predisposing to polypharmacy and excessive polypharmacy, and to identify seniors who are most likely to require multidisciplinary interventions in the field of pharmacotherapy. PATIENTS AND METHODS: We analyzed the use of all prescription and nonprescription drugs taken within 2 weeks preceding the study in a representative national sample of 3014 home­dwelling seniors aged over 65 years. The variables of age, sex, place of residence, level of education, and multimorbidity were considered. Poststratification was used to balance the sample structure to match the Polish population of 2017. RESULTS: Consumption of at least 1 drug was reported by 90.7% of the participants, and the mean number of drugs used was 5.01 (95% CI, 4.87-5.15). At least 1 nonprescription drug was used by 44.2% of the respondents, with a mean number of 0.52 (95% CI, 0.49-0.55). More than 5 drugs were taken by 53.5% of the entire population, while the use of more than 10 drugs was reported by 8.7% of the respondents, with multimorbidity as the most predisposing factor. Single­pill combinations accounted for 27.2% of medications. CONCLUSIONS: The high prevalence of polypharmacy resulting from multimorbidity confirms the need for the implementation of combined medical and pharmaceutical care of the geriatric patients.

Low-grade chronic inflammation and immune alterations in childhood and adolescent cancer survivors: A contribution to accelerated aging?

BACKGROUND: The long-term consequences of chemotherapy and radiotherapy result in a high prevalence and early onset of age-related chronic diseases in survivors. We aimed to examine whether childhood and adolescent cancer survivors (CS) demonstrate biomarkers of accelerated aging. METHODS: We evaluated 50 young adult CS at 11 [8-15] years after cancer diagnosis, and 30 healthy, age and sex-matched controls, who were unexposed to cancer therapy. Using a machine-learning approach, we assessed factors discriminating CS from controls and compared selected biomarkers and lymphocyte subpopulations with data from the Framingham Heart Study (FHS) cohort and the Genotype Tissue Expression (GTEx) project. RESULTS: Survivors compared with controls had higher levels of C-reactive protein and fibrinogen. The surface expression of CD38 on T cells was increased, and there was an increase in the percentage of memory T cells in survivors, compared with the unexposed group. The relationships between above cell subpopulations and age were consistent in CS, FHS, and GTEx cohorts, but not in controls. CONCLUSIONS: Young pediatric cancer survivors differ from age-related controls in terms of activation of the adaptive immune system and chronic, low-grade inflammation. These changes resemble aging phenotype observed in older population. Further research in biomarkers of aging in young, adult childhood cancer survivors is warranted, as it may facilitate screening and prevention of comorbidities in this population.

Cardiovascular risk factors as determinants of cerebral blood flow - a cross-sectional and 6-year follow-up study.

Purpose: The parameters of cerebral blood flow are modulated by many factors. The aim of the study was to prospectively assess the relationship between the number of the established cardiovascular risk factors and hemodynamic parameters of cerebral blood flow.Material and methods: The study was cross-sectional baseline and 6-year follow-up data analysis. We analyzed data regarding cardiovascular risk factors, medications use, and ultrasonographically (transcranial Doppler) obtained mean cerebral blood flow velocity (mCBFV), pulsatility (PI), resistance (RI) indexes of middle cerebral artery.Results: After 6.0 ± 0.6 years of follow-up, there was increase in systolic (p = .047), and decrease in diastolic (p = .005) blood pressure, resulting in greater pulse pressure (p < .001). Although intima-media thickness increased during follow-up (p = .019), PI, RI and mCBFV did not differ between baseline and follow-up. In the cohort without follow-up (n = 112), we observed strong association between number of studied cardiovascular risk factors and lower mCBFV, and higher PI and RI (all p < .001), in the cohort with 6 year follow-up (n = 53), we confirmed similar association for mCBFV and PI (p = .002) at baseline, and mCBFV (p = .024) after follow-up. During follow-up, more patients were treated with vasoactive medications (p < .05). Also the median (interquartile range) of total number of taken drugs at follow-up 2 (1-3) was greater than at baseline 1 (0-2), (p < .001). The addition of vasoactive medications during follow-up was associated with increase of the mCBFV (0.012 ± 0.02 m/s, p = .013).Conclusion: The parameters of the cerebral blood flow are adversely influenced by accretion of cardiovascular risk factors, both at baseline and after 6 years of follow-up. The addition of a vasoactive medication during follow-up is associated with an increase of the mCBFV, a possibly beneficial effect.

The "Wholesome Contact" non-pharmacological, volunteer-delivered multidisciplinary programme to prevent hospital delirium in elderly patients: study protocol for a randomised controlled trial.

BACKGROUND: In hospital settings, delirium affects as many as 50% of older patients, aggravating their symptoms and worsening their condition, and therefore increasing the risk of in-hospital complications and death. The aim of this study is to assess the efficacy of structured, non-pharmacological care, delivered to older hospitalised patients by trained volunteers (students of medical fields), on the reduction of incidence of adverse health-related outcomes. METHODS/DESIGN: This trial will be a randomised, investigator-blind, controlled trial conducted in an internal medicine and geriatric ward in Poland. We aim to include 416 patients who are 70 years of age and have been hospitalised for medical reasons. Eligible patients will be randomised 1:1 to receive structured, non-pharmacological care delivered by students of medicine, psychology and nursing, together with standard medical treatment or standard medical care alone. The protocol of interventions has been designed to cover nine main risk factors for delirium, with the scope of multidisciplinary interventions being individualised and tailored. The protocol will be aimed at immobilisation, vision and hearing impairment, cognitive impairment and disorientation, stress and anxiety, sleep-wake cycle disturbances, dehydration and malnutrition, and pain. A structured evaluation of patients' cognition, mood, anxiety and functional performance is planned to be carried out twice, on the day of group allocation and at discharge; structured screening assessment for delirium will be conducted daily using the Confusion Assessment Method. The primary outcome will be the incidence of delirium in hospital; secondary outcomes will be in-hospital changes in cognition, mood and anxiety, and functional status, occurrence of falls and death. DISCUSSION: Delirium prevention programmes are being introduced worldwide. A particular novelty of our project, however, is that invitations for voluntary work with older patients at risk for delirium will be addressed to medical students. With the use of the service learning method, the students will shape their attitudes, increase their knowledge and understanding of hospital care, and master competencies to work within interdisciplinary teams, which establishes the originality and practicality of the project.

Chronic heart failure management in primary healthcare in Poland: Results of a nationwide cross-sectional study.

BACKGROUND: Organizational and educational activities in primary care in Poland have been introduced to improve the chronic heart failure (CHF) management. OBJECTIVES: To assess the use of diagnostic procedures, pharmacotherapy and referrals of CHF in primary care in Poland. METHODS: The cross-sectional survey was conducted in 2013, involving 390 primary care centres randomly selected from a national database. Trained nurses contacted primary care physicians who retrospectively filled out the study questionnaires on the previous year's CHF management in the last five patients who had recently visited their office. The data on diagnostic and treatment procedures were collected. RESULTS: The mean age ± SD of the 2006 patients was 72 ± 11 years, 45% were female, and 56% had left ventricular ejection fraction <50%. The percentage of the CHF patients diagnosed based on echocardiography was 67% and significantly increased during the last decade. Echocardiography was still less frequently performed in older patients (≥80 years) than in the younger ones (respectively 50% versus 72%, Ρ <0.001) and in women than in men (62% versus 71%, P <0.001). The percentage of the patients treated with ß-blocker alone was 88%, but those with a combination of angiotensin inhibition 71%. The decade before, these percentages were 68% and 57%, respectively. Moreover, an age-related gap observed in the use of the above-mentioned therapy has disappeared. CONCLUSION: The use of echocardiography in CHF diagnostics has significantly improved in primary care in Poland but a noticeable inequality in the geriatric patients and women remains. Most CHF patients received drug classes in accordance with guidelines.

Nonpharmacological Interventions Targeted at Delirium Risk Factors, Delivered by Trained Volunteers (Medical and Psychology Students), Reduced Need for Antipsychotic Medications and the Length of Hospital Stay in Aged Patients Admitted to an Acute Internal Medicine Ward: Pilot Study.

Purpose. Effectiveness of nonpharmacological multicomponent prevention delivered by trained volunteers (medical and psychology students), targeted at delirium risk factors in geriatric inpatients, was assessed at an internal medicine ward in Poland. Patients and Methods. Participants were recruited to intervention and control groups at the internal medicine ward (inclusion criteria: age ≥ 75, acute medical condition, basic orientation, and logical contact on admission; exclusion criteria: life expectancy < 24 hours, surgical hospitalization, isolation due to infectious disease, and discharge to other medical wards). Every day trained volunteers delivered a multicomponent standardized intervention targeted at risk factors of in-hospital complications to the intervention group. The control group, selected using a retrospective individual matching strategy (1 : 1 ratio, regarding age, gender, and time of hospitalization), received standard care. Outcome Measures. Hospitalization time, deaths, falls, delirium episodes, and antipsychotic prescriptions were assessed retrospectively from medical documentation. Results. 130 patients (38.4% males) participated in the study, with 65 in the intervention group. Antipsychotic medications were initiated less frequently in the intervention group compared to the control group. There was a trend towards a shorter hospitalization time and a not statistically significant decrease in deaths in the intervention group. Conclusion. Nonpharmacological multicomponent intervention targeted at delirium risk factors effectively reduced length of hospitalization and need for initiating antipsychotic treatment in elderly patients at the internal medicine ward.

Osteoprotegerin and TRAIL in Acute Onset of Atrial Fibrillation.

BACKGROUND: There is a growing amount of evidence that inflammatory processes are involved in the development of atrial fibrillation (AF) and its complications. We decided to investigate the behavior of osteoprotegerin (OPG) and TNF-related apoptosis inducing ligand (TRAIL) in terms of acute onset of AF. METHODS AND RESULTS: We included 60 patients with acute onset of AF, candidates for pharmacological cardioversion. The presence of cardiovascular comorbidities was connected with higher concentration of OPG and lower level of TRAIL right from the first hours of AF paroxysm. The initial TRAIL level correlated also positively with left ventricle ejection fraction and negatively with left atrium diameter. We found subsequent increase of OPG in subgroups selected on the basis of CHA2DS2-VASc scoring. Although basal concentrations of studied markers did not allow prediction of the restoration of sinus rhythm, we observed important increase of TRAIL concentration in subgroup with sinus rhythm maintenance (94.11 ± 29.46 versus 111.39 ± 30.23 pg/mL; p = 0.002). CONCLUSIONS: OPG and TRAIL are associated with the underlying cardiovascular damage in AF, but their balance is modulated by the fact of sinus rhythm restoration. Determining the suitability of OPG and TRAIL as predictive markers in AF requires further prospective studies.

Correlations of C-reactive protein, von Willebrand factor, and carotid artery intima-media thickness with CHA2DS2-VASc in patients with acute atrial fibrillation.

INTRODUCTION: The risk of stroke in patients with atrial fibrillation (AF) seems to be independent of the presence or duration of arrhythmia at a given moment. However, there is no single approved measurable parameter that would allow to predict the risk of stroke in patients with newly diagnosed AF. OBJECTIVES: We aimed to determine the levels of von Willebrand factor (vWF) and high-sensitivity C-reactive protein (hs-CRP) as well as to measure the intima-media thickness (IMT) in patients in the first hours of an AF episode and compare these markers with predicted risk of stroke. PATIENTS AND METHODS: The study group consisted of 60 consecutive adult patients with symptomatic AF lasting less than 48 hours. In all patients, vWF and hs-CRP levels as well as IMT were measured and compared with the calculated CHA2DS2-VASc score. RESULTS: We found a significant difference in the levels of the measured markers (vWF, 110.3% [range, 92.3%-124.2%] vs 170.2% [range, 111.1%-219.5%], P <0.005; hs-CRP, 1.08 mg/l [range, 0.46-2.49 mg/l] vs 3.43 mg/l [range, 1.59; 5.95 mg/l]; P <0.005) and IMT (0.62 mm [range, 0.56-0.71 mm] vs 0.75 mm [range, 0.63-0.81 mm], P = 0.01) between patients with a CHA2DS2-VASc score of less than 2 and those with a score of 2 or higher. Using the receiver operating characteristic curves, we determined the optimal cut-off points for hs-CRP (1.27 mg/l), vWF (153.25%), and IMT (0.65 mm), which allowed us to identify patients requiring oral anticoagulation. CONCLUSIONS: The tested parameters allow, with moderate sensitivity and specificity, to predict the presence of indications for chronic oral antithrombotic prophylaxis in patients with newly diagnosed AF. In order to determine the real ability of these parameters to predict stroke, a prospective long-term follow-up is required.

Epidemiology and management of coexisting heart failure and atrial fibrillation in an outpatient setting.

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia complicating heart failure (HF). The coexistence of these diseases may be partially explained by the presence of common risk factors. Although the effect of AF on the prognosis in HF is still debatable, it is associated with specific complications and affects therapy. OBJECTIVES: The aim of this analysis was to evaluate epidemiology and management of coexisting HF and AF among Polish outpatients. PATIENTS AND METHODS: The present study was performed within the framework of the Polish National Cardiovascular Disease Prevention and Treatment Program, POLKARD 2003-2005, and included patients with HF treated in a representative number of 400 outpatient clinics. Data was collected using questionnaires and included demographic characteristics as well as information about coexisting diseases and treatment, provided by patients and physicians on the basis of the available medical records. RESULTS: The study involved 3682 patients with HF (mean age 67.1 ±11.7 years; 58% of patients were men). AF was present in 38% of the patients. The prevalence of arrhythmia increased with the New York Heart Association class. We observed significant differences between the subgroups of patients with AF and those with sinus rhythm in terms of demographic parameters, risk factors, concomitant diseases, and therapy. Although the use of angiotensin-converting enzyme inhibitors and ß-blockers was significantly lower in the subgroup with AF, a multivariable analysis showed that it was associated with specific demographic characteristics and comorbidities rather than with arrythmia itself. Specialty patient care was associated with increased use of therapy aimed to improve the prognosis of HF patients. CONCLUSIONS: Patients with AF constitute a particular subgroup within the population of patients with HF. A specific distribution of risk factors with a significant effect of noncardiac diseases may confound HF therapy in this patient group. Specialty care may be able to optimize treatment in patients with coexisting HF and AF.

[Analysis of severe and threefold atypical and serious course of catatonic-paranoid psychosis]. / Analiza ciezkiego i potrójnie nietypowego przebiegu psychozy katatoniczno-paranoidalnej.

The paper describes the difficult course of catatonic-paranoid psychosis which began with symptoms similar to the myasthenia. The growing symptoms of catatonia (in this oral mechanisms with the compulsion of mastication, injuring with teeth of the mouth, tongue biting and damage, such as lockjaw) brought about choking which was followed by aspiration pneumonia. The patient had to have pharmacological coma induced, along with muscle relaxation and artificial ventilation in the conditions of the intensive care department. Despite treatment with high doses of neuroleptics, the repeated trials of bringing the patient out from the coma caused recurrence of the catatonic symptoms. A decision was made to go along with electroconvulsive therapy. During one of the ECT treatments there were complications in the form of circulation cessation which required defibrillation. The paper contains basic information about the serious complications of the electroconvulsive therapy. It moreover carries out the critical analysis of the whole treatment period.

Ten-year follow-up after in-hospital adult cardiac arrest.

BACKGROUND: The aim of the study was to determine the prevalence of in-hospital cardiac arrest and survival during 10 years of observation. STUDY GROUP: patients hospitalized in the Internal Medicine Unit (including Intensive Care) in the years 1995-1997 with cardiac arrest during hospitalization. The probable reasons for the cardiac arrest were defined (cardiac or non-cardiac) as well as the mechanism (VF/VT, other). The number of deaths during the first 24 hours from the episode, during the whole stay in the hospital and after one, five and ten-years was analyzed. RESULTS: During the period examined, 152 cardiac arrests took place. The resuscitation was successful in 83 cases. In that group, 66% patients had cardiac cause of cardiac arrest, 50.6% in the mechanism of VF. Ninety percent of the patients died during their stay in the hospital (38.5% during the first 24 hours after the episode), 10% of the patients left the hospital alive. Only 2 of them (2.4%) survived the next 5 years. Nobody survived 10 years. CONCLUSIONS: Cardiac arrest within the internal ward was characterized by high in-hospital mortality risk and unsuccessful late prognosis. Non-cardiac cause of cardiac arrest, relatively common in cases of in-hospital cardiac arrest, is connected with better survival after the first 24 hours; however, it does not improve the general survival to hospital discharge.

Knowledge of antithrombotic prophylaxis among patients with atrial fibrillation.

BACKGROUND: Effective and safe anticoagulative therapy needs close co-operation between doctor and patient, the latter being well-informed. The aim of the study was to assess knowledge of oral anticoagulation in a group of patients with atrial fibrillation (AF) treated with acenocoumarol and to determine the relationship between knowledge and INR value. METHOD: The study group consisted of patients with AF who were continuously using anticoagulative therapy and who were admitted to hospital (for different reasons). The questionnaire comprised questions about their knowledge of various aspects of the treatment used. In the assessment of knowledge a numerical scale was introduced (0-9 points) and the patients were given one point for each correct answer. RESULTS: The study group consisted of 61 patients aged 46-91 (mean 70.18). The level of knowledge of oral anticoagulation among the group of patients examined was low (the mean number of points achieved was 4.19 in the 9-point scale). Sex, education and the reason for admission had no relationship with the level of knowledge. Younger patients (4.85 +/- 1.94 vs. 3.56 +/- 1.86, p = 0.01) and those who had INR within the therapeutic limits at the moment of admission to the hospital (5.50 +/- 1.79 vs. 3.56 +/- 1.79 points, p = 0.0003) had a higher level of knowledge of the antithrombotic treatment. CONCLUSIONS: Knowledge of treatment with acenocoumarol among the patients with atrial fibrillation using oral anticoagulation is low and inversely correlated with age. The greater the knowledge, the better is the value of INR controlled. (Cardiol J 2007; 14: 44-49).

Myocarditis related to Salmonella enteritidis infection.

Myocarditis associated with bacterial enteritis has only rarely been described in literature. The clinical manifestation of the disease is often oligosymptomatic, so the real incidence could be underestimated. A case of myocarditis in a 31-year-old male patient having Salmonella enteritidis infection is reported. The clinical course and problems concerning the diagnosis are discussed. The possibility of myocardial infection should be considered in any patient with cardiac complaints during gastrointestinal infection. (Cardiol J 2007; 14: 589-591).
