Lithuanian High Cardiovascular Risk (LitHiR) primary prevention programme - rationale and design

Lithuanian High Cardiovascular Risk (LitHiR) primary prevention programme - rationale and design Objectives: According to the latest WHO data, coronary heart disease deaths in Lithuania reached 38.3% of total deaths. Based on the unfavourable situation with cardiovascular morbidity and mortality in Lithuania the Lithuanian High Cardiovascular Risk (LitHiR) programme aimed at estimation and aggressive managing of cardiovascular risk factors. This paper describes the Lithuanian High Cardiovascular Risk programme protocol. Design and methods: In 2006 the Lithuanian High Cardiovascular Risk programme was started. LitHiR programme recruited men - at the age of 40-54 years and women - 50-64 years without overt cardiovascular disease. The two-level approach - primary health care institutions (PHCI) and specialized cardiovascular prevention units (CVPU) - was applied. The subjects selected were tested for cardiovascular risk and those with high cardiovascular risk were sent to secondary (CVPU) level, for other the plan of preventive measures of risk factor reduction was created. In years 2006-2010 overall 266,391 persons (36.9% from all target population) were examined. Among them 164,657 subjects (61.8%) were tested for the first time, 68,832 (25.8%) were tested repeatedly one time, 32,848 subjects (12.3%) were tested repeatedly for two and more times. Conclusions: The programme aimed at estimation and managing of cardiovascular risk factors striving to reduce acute cardiovascular event related morbidity and mortality, to slow down the progression of sub-clinical atherosclerosis into overt cardiovascular disease, to increase the number of newly identified cases of diabetes, metabolic syndrome and latent course of atherosclerosis related diseases, to decrease hospitalizations for treatment of arterial hypertension and coronary heart disease.

The association between phenomena on the Sun, geomagnetic activity, meteorological variables, and cardiovascular characteristic of patients with myocardial infarction

It has been found that solar and geomagnetic activity affects the cardiovascular system. Some evidence has been reported on the increase in the rate of myocardial infarction, stroke and myocardial infarction related deaths during geomagnetic storms. We investigated the association between cardiovascular characteristics of patients, admitted for myocardial infarction with ST elevation (STEMI), and geomagnetic activity (GMA), solar proton events (SPE), solar flares, and meteorological variables during admission. The data of 1,979 patients hospitalized at the Hospital of Lithuanian University of Health Sciences (Kaunas) were analyzed. We evaluated the association between environmental variables and patient’s characteristics by multivariate logistic regression, controlling patient’s gender and age. Two days after geomagnetic storms the risk of STEMI was over 1.5 times increased in patients who had a medical history of myocardial infarction, stable angina, renal or pulmonary diseases. The dose–response association between GMA level and STEMI risk for patients with renal diseases in history was observed. Two days after SPE the risk of STEMI in patients with stable angina in anamnesis was increased over 1.5 times, adjusting by GMA level. The SPE were associated with an increase of risk for patients with renal diseases in history. This study confirms the strongest effect of phenomena in the Sun in high risk patients.

Clinical-Technical Performance and Physician Satisfaction with a Transnational Telephonic ECG System

The effective use of cardiology hospital services could improve patient safety while shortening pre- and in-hospital stay periods using modern transtelephonic technologies and consultations by phone to follow up electrocardiograph (ECG) changes of the patients on a waiting list. The aim of this study was to assess clinical-technical performance and satisfaction with application of an international telephonic ECG system. A transnational telephonic ECG system was established between Lithuania and Germany. A follow-up study design was used to assess clinical-technical performance and user satisfaction with the system. According to inclusion and exclusion criteria, 34 patients were enrolled who transmitted 329 ECGs, of which 14 ECGs showed clinical changes. Of the ECGs sent 254/329 (77%) were of good quality, 9 (3%) were of moderate quality, and 66 (20%) were of bad quality. Among physicians surveyed, 77.6% were satisfied or very satisfied with telemedicine services. A telecardiology service can help to identify patients with urgent problems requiring rapid assessment at the hospital. The service has high acceptance from physicians but needs to be improved in terms of technical performance and patient compliance expectations.

Clinical relevance of high sensitivity C-reactive protein in cardiology

Coping with cardiovascular diseases (CVD), which are of the main causes of death worldwide, has influenced investigation of high sensitivity CRP (hsCRP) and its role in pathogenesis, prognosis and prevention of CVD. hsCRP can be synthesized in vascular endothelium, atherosclerotic plaques, and theory of inflammatory origin of atherosclerosis is being more widely debated, raising questions, whether higher hsCRP plasma concentration might be the cause or the consequence. Summing up controversial data from multiple studies, guidelines recommend hsCRP testing for both, primary (stratifying CVD risk groups, selecting patients for statin therapy) and secondary CVD prevention (prognosis of CVD and its treatment complications, evaluation of treatment efficacy in moderate CVD risk group). hsCRP testing also has role in heart failure, atrial fibrillation, arterial hypertension, valve pathology and prognosis of coronary stent thrombosis or restenosis. Medications (the well-known and the new specific - CRP binding) affecting its concentration are being investigated as well.

Factors Affecting Relevance of Tele-ECG Systems Application to High Risk for Future Ischemic Heart Disease Events Patients Group

Telecardiology can identify patients with urgent problems requiring rapid assessment at the hospital or even emergency admission. Telemedicine applications in cardiology must identify factors that make the service most beneficial to the patients. The aim of the study was to analyze factors affecting relevance and benefits of telephonic electrocardiography (ECG) consultations. A transnational telephonic ECG system was established between Lithuania and Germany. Using a follow-up study design, clinical performance and beneficial factors for telecardiology were assessed. According to inclusion and exclusion criteria, 34 patients sent 329 ECGs with 14 ECG showing important clinical changes. Of the 329 ECGs only 263 (80%) ECGs were of acceptable quality for clinical interpretation. Most important factors associated with benefits from tele-ECG service were gender, Thrombolysis in Myocardial Infarction (TIMI), Systematic Coronary Risk Evaluation (SCORE) risk stratification, and chest pain in previous month. Tele-ECG service of routine ECGs can be useful in recognition of silent ischemia or arrhythmias, and facilitating diagnosis. However, other factors such as chest pain in the previous month, gender, TIMI, and SCORE risk stratifications are important in planning tele-ECG services.

Prevalence of dyslipidemia in statin-treated patients in the Baltic states (Estonia, Latvia, and Lithuania): Results of the Dyslipidemia International Study (DYSIS)

BACKGROUND AND OBJECTIVE The Baltic nations (Estonia, Latvia, and Lithuania) are profoundly affected by cardiovascular disease (CVD). Studies have indicated that patients may experience persistent dyslipidemia despite chronic statin treatment. Therefore, the aim of this study was to analyze the risk factors for dyslipidemia despite statin-treatment in a large dataset from the Baltic nations. MATERIAL AND METHODS Patients in primary care centers across the Baltic nations were enrolled into the cross-sectional, observational Dyslipidemia International Study (DYSIS). Patients were ≥ 45 years old and had been treated with statins for at least three months. Patient characteristics and lipid measurements were used to determine variables contributing to dyslipidemia (abnormal low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], or total triglyceride [TG] values). RESULTS We enrolled 1797 patients with a mean age of 66.1 years and 59.1% being female. Overall 63.4% had cardiovascular disease, 30.1% were diabetic and 77.8% at high risk for cardiovascular complications. LDL-C was not at target level for 80.7%; low HDL-C levels were observed for 26.0%, and elevated TG levels were found in 35.0% of all patients. Multivariate analyses indicated that a BMI ≥ 30 kg/m(2) (OR, 2.12; 95% CI, 1.45-3.08) and hypertension (OR, 2.43; 95% CI, 1.1 6-5.10) were strongly associated with dyslipidemia (involving all three lipids) during statin therapy while age ≥ 70 years (OR, 0.63; 95% CI, 0.42-0.94) and female gender (OR, 0.48; 95% CI, 0.33-0.68) conferred reduced risk. CONCLUSIONS Our findings indicate many statin-treated patients in Estonia, Latvia, and Lithuania did not meet target lipid levels and had a very high risk of CVD. Combating other well-known CVD risk factors such as obesity and hypertension is vital to reduce the exceptionally high risk for CVD mortality seen in the Baltic nations.

The fear of dying and occurrence of posttraumatic stress symptoms after an acute coronary syndrome: A prospective observational study:

The purpose of the study was to investigate whether experiencing fear of dying after acute coronary syndrome predicts later posttraumatic stress symptoms. We enrolled 90 patients hospitalized with main diagnosis of acute coronary syndrome and assessed baseline characteristics. One month after discharge, we collected the Posttraumatic Stress Scale. A total of 24 patients (26.7%) developed posttraumatic stress symptoms 1 month after the acute coronary syndrome event. Patients with posttraumatic stress symptoms reported significantly greater fear of dying, helplessness, avoidance-focused coping, and severe anxiety. In our prospective study, fear of dying was associated with occurrence of posttraumatic stress symptoms in patients hospitalized with acute coronary syndrome.

Prevalence of cardiovascular risk factors in Lithuanian middle-aged subjects participating in the primary prevention program, analysis of the period 2009–2012

Abstract Background. The aim of this study was to assess the prevalence and changes of cardiovascular risk factors in the middle-aged Lithuanian subjects after conducting the primary prevention program. Design and methods. Four cross-sectional investigations of cardiovascular risk factors were conducted in 2009 (n = 9625), 2010 (n = 7716), 2011 (n = 5018) and 2012 (n = 4348). The program recruited men aged 40–54 and women aged 50–64 without overt cardiovascular disease. Results. During the period 2009–2012, the mean number of risk factors significantly increased (from 3.95 to 4.03, p < 0.001), while the numbers of people having metabolic syndrome (from 34.1% to 28.7%; p < 0.001), arterial hypertension (from 60.2% to 54.5%; p < 0.001), the average body mass index (BMI) value (from 29.17 to 28.92 kg/m2; p = 0.001) and abdominal obesity (from 48.4% to 45.3%; p < 0.001) significantly decreased. The percentage of subjects with dyslipidemia, as well as the average values of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglycerides, remained unchanged. The percentage of smoking subjects have significantly increased (from 19.3% to 22.7%; p < 0.001). Conclusions. The analysis showed that the prevalence of arterial hypertension, metabolic syndrome and obesity in Lithuania is slowly decreasing while conducting the primary prevention program; however, dyslipidemia, diabetes mellitus and smoking are still hard to manage for both genders.

Effectiveness of telemedicine and distance learning applications for patients with chronic heart failure. A protocol for prospective parallel group non-randomised open label study

Introduction Chronic heart failure in Baltic Sea Region is responsible for more hospitalisations than all forms of cancer combined and is one of the leading causes of hospitalisations in elderly patients. Frequent hospitalisations, along with other direct and indirect costs, place financial burden on healthcare systems. We aim to test the hypothesis that telemedicine and distance learning applications is superior to the current standard of home care. Methods and analysis Prospective parallel group non-randomised open label study in patients with New York Heart Association (NYHA) II–III chronic heart failure will be carried out in six Baltic Sea Region countries. The study is organised into two 6-month follow-up periods. The first 6-month period is based on active implementation of tele-education and/or telemedicine for patients in two groups (active run period) and one standard care group (passive run period). The second 6-month period of observation will be based on standard care model (passive run period) to all three groups. Our proposed practice change is based on translational research with empirically supported interventions brought to practice and aims to find the home care model that is most effective to patient needs. Ethics and dissemination This study has been approved by National Bioethics Committee (2011-03-07; Registration No: BE-2-11). Trial Registration This study has been registered in Australian New Zealand Clinical Trials Registry (ANZCTR) with registration number ACTRN12611000834954.

The risk of cardiovascular death following the first acute ischaemic syndrome: experience in Kaunas between 1997 and 2001

The aim of our study was twofold: initially to investigate the effects of the informative value of the variables of the acute period on the risk of cardiovascular death during the long-term period following the first acute coronary syndrome, and then to determine the long-term survival rate in different risk groups. Methods — The prospective five-year observational study included 732 patients with acute coronary syndrome who had survived the hospital period. Employing multivariable Cox’s proportional-hazard analysis, the most informative variables were selected, the risk score index was calculated, the risk groups for the prediction of cardiovascular death were identified, long-term survival (4.5 ± 2.1 years) in different risk groups was determined and internal validation of the model was performed. Results — During the observational period, 84 patients (11.5%) died due to cardiovascular causes. Cox proportional-hazard models demonstrated that six variables had significant influence on long-term survival during the five-year period after an acute coronary syndrome. These variables were: age [1-5 points], the presence of pathologic Q wave in > 2 ECG leads [2 points], Killip class II-IV [24 points], left ventricular ejection fraction < 35% [2-4 points], proximal stenosis of coronary arteries [2-4 points], absence of myocardial revascularization in the acute period [2 points].Three strata for risk of cardiovascular death were identified [0-5 points - 14.1% patients, 6-10 points - 62.6%, > 10 points - 23.3%].The probability of survival within the period of five years was found to be favourable for the majority of patients in the low- and medium-risk groups, while the number of such patients in the high-risk group was significantly lower [97.0% vs. 89.0% vs. 73.0%, P< 0.0000].The difference in the survival probability was negligible in developmental and validation sets. Conclusion — The risk score derived from clinical variables of first acute coronary syndromes permits a reliable determination of risk for cardiovascular death as well as the prediction of long-term survival in different risk groups.
