Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia, characterized by an increased risk of thromboembolic complications that can be markedly reduced with anticoagulation. There is a paucity of studies assessing the total prevalence of AF in national populations. Aims:To assess the nationwide prevalence of AF in a population of adults ≥65 old and to determine the impact of duration of electrocardiogram (ECG) monitoring on the number of newly detected AF episodes. Methods:The NOMED-AF study (ClinicalTrials.gov; NCT: 0324347) was a cross-sectional study performed on a nationally representative random sample of 3014 Polish citizens 65 years or older. Final estimates were adjusted to the national population. All participants underwent up to 30 days of continuous ECG monitoring. Total AF prevalence was diagnosed based on the patient's medical records or the presence of AF in ECG monitoring. Results:The prevalence of AF in the Polish population ≥65 years was estimated as 19.2% (95% confidence interval [CI], 17.9%-20.6%). This included 4.1% (95% CI, 3.5%-4.8%) newly diagnosed cases and 15.1% (95% CI, 13.9%-16.3%) previously diagnosed cases and consisted of 10.8% (95% CI, 9.8%-11.9%) paroxysmal AF and 8.4% (95% CI, 7.5%-9.4%) persistent/permanent AF. The incidence of all paroxysmal AF events as a function of ECG monitoring duration increased from 1.9% (95% CI, 1.4%-2.6%) at 24 hours to 6.2% (95% CI, 5.3%-7.2%) at 4 weeks. Conclusions:The prevalence of AF in elderly adults is higher than estimated based on medical records only. Four weeks of monitoring compared to 24-hour ECG Holter allow detection of 7-fold more cases of previously undiagnosed paroxysmal AF.
Background Atrial fibrillation (AF) confers a high healthcare burden from stroke, heart failure, dementia and hospitalisation, and one challenge is. Early detection of this arrhythmia in the community, given that it is often asymptomatic. Aim To perform population screening for atrial fibrillation and flutter (AF/AFl) using a mobile long-term continuous ECG telemonitoring vest in a representative Polish and European population aged ≥65 years (age range 65–100 years). Methods The NOMED-AF study is a cross-sectional study based on a representative sample of adults aged ≥65 years (n=3014; mean age 77.5±7.9 years; 49.1% female). All study participants were equipped with a mobile long-term continuous ECG telemonitoring vest. National and European estimations were calculated on weighted data. Results In 680 subjects AF/AFl (including 279 with SAF; 9.3%) was confirmed. In the NOMED-AF population, the prevalence of AF/AFl was 22.6%, estimated to be 19.2% for Poland [1,251,100 (95% CI: 1,158,300–1,344,000) and 480,100 (95% CI: 426,60–533,700) subjects with AF/AFl and SAF, respectively] and 20.4% for Europe [20,300,000 (95% CI 18.8–21.9 M), including 8,000,000 (95% CI: 6.9–9.3 M) subjects with AF/AFl and SAF, respectively]. The prevalence of AF/AFl was 2.56-fold higher in men than in women and the incidence of silent AF (SAF) was 4.73-fold higher in men than in women. Although the risk of either AF/AFl or SAF increased with age, the odds ratio was significantly higher in women of a particular age group than in men of the corresponding age. Based on our survey, the total number of subjects with AF/AFl in Europe is estimated to be roughly 20.3 million (95% CI 18.8–21.9M), including 8.0 million (95% CI: 6.9–9.3M) subjects with silent AF/AFl (Figure). Conclusions Approximately 1 in 5 subjects aged ≥65 years suffers from AF/AFl. The risk for AF/AFl and SAF is higher in men than that in women, but when correlated to a particular age group, the risk increases significantly in women. Continuous ECG telemonitoring allows for more credible AF/AFl and SAF detection. Funding Acknowledgement Type of funding source: Public Institution(s).

Background The 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) guidelines for the management of arterial hypertension and the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline for the prevention, detection, evaluation, and management of high blood pressure in adults differ in approach to defining stages of hypertension and recommendations for treatment of high blood pressure. Purpose To contrast the implications of the ESC/ESH versus ACC/AHA hypertension guidelines among the general population in Poland – a country representing a high CVD risk region in Europe. Methods We used data from a representative random sample of 1439 Polish adults aged 40 to 79 from the research program NATPOL 2011. The analysis was weighted in order to reflect the structure of the population in Poland and was stratified by age and gender. We applied the ESC/ESH 10-year SCORE (Systematic COronary Risk Evaluation) and the ACC/AHA ASCVD (atherosclerotic CV disease) risk assessment tools and followed guideline-specific algorithms to detect hypertension and follow recommendations for treatment. Results The overall prevalence of hypertension among Polish adults according to the ACC/AHA guideline was 76.9% (95% CI, 74.7–79.0%) versus 51.8% (95% CI, 49.2–54.4%) according to the ESC/ESH guidelines. Application of the ACC/AHA guideline recommendations would result in antihypertensive drug treatment for 63.0% (95% CI, 60.5–65.5%) of Polish adults compared with 46.2% (95% CI, 43.6–48.7%) based on application of the ESC/ESH guidelines (difference 16.8% (95% CI, 14.9–18.8%), table 1).

Introduction. Arterial hypertension (AH) and cigarette smoking are a leading health and social problem in Polish population. Still around 24% of Poles are chronic smokers. Despite the high risk of cardio-vascular and oncological complications the number of papers assessing wellbeing and health condition of chronic smokers is low. Material and methods. As part of the Moltest Kardio+ program 425 citizens of pomorskie voivodeship (223 males, 52.47%) were examined. Inclusion criteria were age between 50 and 79 years and history of smoking with more than 30 pack years. Program consisted of one visit during which medical history, anthropometric measurements and three separate blood pressure measurements were taken. The results were then compared to the general population (NATPOL 2011 study). Results. There were no differences between SBP and DBP values in Moltest Kardio+ and NATPOL 2011 populations. Prevalence of AH was not significantly different in both populations. Significant differences in SBP according to number of pack years were noted. In Moltest study women had significantly lower BMI than those in general population, whereas men's BMI was significantly higher. Conclusions. Mean SBP and DBP values and prevalence of AH are not significantly different in these two groups. Number of pack years had a significant effect on SBP values in smokers. Entirely opposite relations between smoking and BMI index values were observed in female and male smokers. Higher prevalence of body mass disorders and concomitance of AH and chronic smoking in male smokers resulting in increased cardiovascular risk requires to undertake more intense preventive measures.
