Is the 2016 ESC diagnostic algorithm useful for assessing the prevalence of chronic heart failure in population-based studies?

BACKGROUND

Chronic heart failure (CHF) is a major healthcare problem. However, there are no epidemiological studies assessing the prevalence of CHF in the general population with diagnosis based on algorithms recommended for clinical practice.

AIM

The aim of the HF-Pomorskie survey was to assess the prevalence of three basic components of the 2016 ESC diagnostic algorithm for CHF (symptoms, N-terminal pro B-type natriuretic peptide [NT-proBNP], and abnormalities on echocardiography) and to determine whether this algorithm may be applicable to studies in general population samples.

METHODS

The study was performed in a representative sample of 313 adults (170 women and 143 men) aged between 20 and 90 years (mean 55.2 years [15.3]) in Northern Poland. A questionnaire to determine New York Heart Association [NYHA] class, laboratory tests including NT-proBNP, as well as transthoracic echocardiography and spirometry examinations were performed in all subjects.

RESULTS

Dyspnea (NYHA class II-IV) was reported by 13.7% of recruited participants. Dyspnea and elevated levels of NT-proBNP (>125 pg/ml) were found in 7.7% of all examined subjects, while dyspnea, elevated NT-proBNP levels accompanied by systolic or diastolic abnormalities on echocardiography occurred in 4.8%. In the group without dyspnea (86.3% of all examined subjects), every sixth subject had an elevated level of NT-proBNP. On the other hand, 5.8% of studied subjects reported a previous diagnosis of CHF, which was confirmed using the current ESC algorithm in 78% of them.

CONCLUSIONS

The prevalence of CHF assessed by the 2016 ESC diagnostic algorithm in the representative sample of adults was equal to 4.8%. The clinical algorithm for the diagnosis of CHF is fully applicable to the representative surveys in the general population. However, due to logistic and economic factors, echocardiography examination and NT-proBNP determination can be limited to patients reporting dyspnea or previous diagnosis of CHF.

The prevalence of dyspnea in the adult Polish population

OBJECTIVES

Dyspnea is one of the most predominant symptom in clinical practice. There is a lack of data about incidents of dyspnea among Polish adults therefore it would be important to establish prevalence of this symptom before COVID-19 pandemic to assess the impact of this infection on the functioning of the adult Polish population in the future. The aim of the study was to establish prevalence of dyspnea in adult Polish population.

MATERIAL AND METHODS

It was an observational-cross-sectional study, with representative sample of adult Poles aged 18-79 years. The 2413 participants were surveyed. Responders were asked if and when dyspnea occurs and what is its severity in relation to 1 of 4 categories (A, B, C, and D) describing the impact of dyspnea on reduced exercise tolerance and daily activities.

RESULTS

The 67.1% of the respondents answered negatively to all question about experiencing dyspnea (females (F) 61% vs. males (M) 74%, p < 0.05). Dyspnea only during intense physical exertion (A), was reported by 22.8% (F 26.2% vs. M 19.2%, p = 0.07). Dyspnea limiting daily activities (B, C and D) was reported by 10.1% (F 13.1% vs. M 7%, p < 0.05). Significant differences in the severity of dyspnea were found between the age groups. People diagnosed with chronic heart failure or lung diseases significantly more often reported dyspnea than people without these conditions.

CONCLUSIONS

Every tenth Pole reported dyspnea limiting performing activities of daily living. Additionally, about 20% of Poles experienced dyspnea considered as "gray area," only during intense physical exertion, that requires deepening and clarifying the medical history.

Prevalence of self-reported heart failure in the adult Polish population: results of the NATPOL 2011 study

INTRODUCTION

Chronic heart failure (CHF) is a growing medical and economic problem, especially in Central and Eastern Europe. However, only a few studies have analyzed the prevalence of CHF in this region.

OBJECTIVES

The aim of the study was to assess the prevalence of CHF in a representative sample of adult Poles.

PATIENTS AND METHODS

The NATPOL 2011 study was a cross-sectional study of a representative sample of the adult Polish population that included 2413 individuals (1168 men, 1245 women) aged 18-79 years (mean age 45.8 (16.7) years). All participants completed a detailed questionnaire and underwent laboratory tests. We have evaluated the prevalence of CHF based on self-reported symptoms, National Health Fund (NFZ) database and NTproBNP level.

RESULTS

Proportion of patients that reported the diagnosis of CHF was 4.3% (95% CI 3.6%-5.2%). Only 0.2% of people aged <40 years reported CHF, compared to 3.2% of those 40-59 years of age and 13.2% of those 60-79 years of age. The distribution of NTproBNP levels in CHF patients was markedly skewed to the right, with the median of 181 pg/ml (interquartile range 90.8-531). Among 104 subjects who declared having CHF, almost fifty six (55.8%) had recorded at least one outpatient visit or hospitalization related to ICD I50 code in NHS database which resulted in 2.4% of confirmed diagnoses of CHF in Polish adults.

CONCLUSIONS

The results of our study indicate that the proportion of inhabitants of Poland aged 18-79 years with heart failure is somewhere between 2.4% and 4.3%. This corresponds to 720 to 1,200 thousands of diagnosed CHF patients in Poland.

New mtDNA Association Model, MutPred Variant Load, Suggests Individuals With Multiple Mildly Deleterious mtDNA Variants Are More Likely to Suffer From Atherosclerosis

The etiology of common complex diseases is multifactorial, involving both genetic, and environmental factors. A role for mitochondrial dysfunction and mitochondrial DNA (mtDNA) variation has been suggested in the pathogenesis of common complex traits. The aim of this study was to investigate a potential role of mtDNA variants in the development of obesity, diabetes, and atherosclerosis in the Polish population. Whole mtDNA sequences from 415 Polish individuals representing three disease cohorts and a control group were obtained using high-throughput sequencing. Two approaches for the assessment of mtDNA variation were applied, traditional mitochondrial haplogroup association analysis and the mutational or variant load model using the MutPred pathogenicity prediction algorithm for amino acid substitutions in humans. We present a possible association between mildly deleterious mtDNA variant load and atherosclerosis that might be due to having more than one likely mildly deleterious non-synonymous substitution. Moreover, it seems largely dependent upon a few common haplogroup associated variants with MutPred score above 0.5.

Cardiovascular diseases prevention in Poland: results of WOBASZ and WOBASZ II studies

BACKGROUND

Cardiovascular diseases are the main cause of morbidity and an important cause of disability and premature death in European countries. Current guidelines recommend prevention delivery by physicians during medical consultations.

AIM

We sought to evaluate the prevention support offered by Polish physicians in 2013-2014 compared to 2003-2005, and its determinants.

METHODS

The data from two population surveys were analysed: WOBASZ (6392 men and 7153 women, aged 20-74 years, screened in 2003-2005) and WOBASZ II (2751 men and 3418 women, aged ≥ 20 years, screened in 2013-2014). For comparison analysis, the population of WOBASZ II was restricted to persons aged 20-74 years. Prevention delivery was assessed using a questionnaire.

RESULTS

Overall, 64% of men and 75% of women screened in 2003-2005 consulted their physicians at least once in the preceding year; 10 years later these rates were 70% and 82%, respectively. In both studies, 70% of respondents recalled having received one piece of prevention advice during a medical consultation. One-third of participants neither received any prevention advice nor had their blood pressure or cholesterol level measured. In WOBASZ II we observed a significant increase in the frequency of counselling regarding smoking cessation, nutrition, and increased physical activity, as well as in the frequency of cholesterol measurements, compared to WOBASZ. The prevention support was related to the health status.

CONCLUSIONS

The prevention support in the years 2013-2014 was better than in 2003-2005, but was still insufficient. About one-third of participants did not receive any preventive advice. The prevention support was offered more often to patients with worse health status.

Prevalence, awareness, treatment and control of hypertension in the adult Polish population - Multi-center National Population Health Examination Surveys - WOBASZ studies

INTRODUCTION

Hypertension is one of the main risk factors of cardiovascular diseases. The first aim of the study was to evaluate the prevalence, awareness and treatment of hypertension as well as treatment effectiveness (blood pressure < 140/90 mm Hg) in a representative sample of the Polish population over the age of 19, examined in the WOBASZ II program. The second aim was to assess the changes in these parameters between 2003-2005 (WOBASZ study) and 2013-2014 in adults aged 20-74.

MATERIAL AND METHODS

Sampling was performed in three stages, stratified according to voivodeship (province), type of commune, and gender. Finally, the study included 6163 persons (3406 women and 2757 men) examined in the years 2013-2014 (aged ≥ 19 years). For comparison the data from 14 755 persons (7783 women and 6452 men aged 20-74 years) examined in the years 2003-2005 were used.

RESULTS

In the years 2013-2014, the age-standardized prevalence of hypertension, awareness, treatment and control was 42.7%, 59.3%, 46.1%, and 23% respectively. In the last decade an increase in the prevalence of hypertension (relative ratio (RR) 1.12; 95% confidence interval (CI): 1.07-1.18), treatment (RR = 1.26; 95% CI: 1.17-1.36) and control (RR = 2.16; 95% CI: 1.9-12.45) was found. In contrast, the awareness decreased nonsignificantly (RR = 0.98; 95% CI: 0.92-1.05).

CONCLUSIONS

The prevalence of hypertension in Poland is high, and increased by about 12% in 10 years. Although the number of treated patients and blood pressure control improved nearly twofold over the last decade, this is still below expectations. Efforts to improve the diagnosis and effective treatment of hypertension in Poland should still be intensified.

Trends in hypertension prevalence, awareness, treatment, and control among Polish adults 75 years and older during 2007-2014

BACKGROUND

The aim of this study was to assess changes in the prevalence, awareness, and treatment of hypertension and its effectiveness between 2007 (WOBASZ Senior study) and 2013-2014 (WOBASZ II) in a sample of the Polish population over the age of 75 years.

METHODS

Sampling had three stages, stratified according to voivodeships, type of community, and gen-der. Finally, the WOBASZ II study included 467 persons (290 women and 177 men). For a comparison of the data, 1096 persons (538 women and 554 men) examined in the WOBASZ Senior study were used.

RESULTS

Systolic and diastolic blood pressures significantly decreased from 153.0 ± 23.9 mmHg to 142.9 ± 22.3 mmHg and from 85.2 ± 11.9 mmHg to 78.4 ± 11.3 mmHg, respectively, from 2007 to 2014 (p < 0.0001). Prevalence of hypertension among people included in WOBASZ studies slightly decreased from 83.8% to 77.9% (rate ratio [RR]: 0.95; 95% confidence interval [CI]: 0.78-1.16) in men, and from 75.4% to 71.8% (RR: 0.93; 95% CI: 0.8-1.09) in women. Hypertension awareness was improved from 59.2% to 72.9% (RR: 1.23; 95% CI: 0.97-1.56) in men, and from 74,8% to 93% (RR: 1.26; 95% CI: 1.01-1.58) in women. The proportion of men and women, with implemented hypertension treatment, increased from 48.4% to 61.1% (RR: 1.26; 95% CI: 1.01-1.58), and from 63.2% to 82.0% (RR: 1.3; 95% CI: 1.1-1.53), respectively. The effectiveness of the treatment was improved over two-fold, there was an increase from 10.3% to 26.8% (RR: 2.65; 95% CI: 1.81-3.89) in men, and from 13.8% to 33.5% in women (RR: 2.44; 95% CI: 1.81-3.3).

CONCLUSIONS

The prevalence of hypertension in Polish seniors remains high, but has decreased slightly in the perspective of the last 7 years. Although treatment and control has improved over the last decade, it remains below expectations. Efforts to improve the diagnosis and effective treatment of hypertension in Polish seniors should be intensified.

Metabolic syndrome and its components in Polish women of childbearing age: a nationwide study

BACKGROUND

Abnormal body mass and related metabolic disorders may affect female reproductive health. The purpose of the study was to determine the prevalence of underweight, overweight, obesity, lipid and glucose metabolism disorders, hypertension, and metabolic syndrome, among Polish women of childbearing age.

METHODS

One thousand five hundred eighty-eight non-pregnant Polish women of childbearing age (20-49 years) who participated in the Multi-Centre National Population Health Examination Survey (WOBASZ II study) in 2013-2014, were assigned to 3 age groups: 20-29 years (n = 403), 30-39 years (n = 600) and 40-49 years (n = 585). Measurements of weight, height, waist circumference, blood pressure, blood lipids, and blood glucose were taken. For statistical analysis, the Kruskal-Wallis, Chi-Square, and Cohran-Armitage tests were used.

RESULTS

Of the participants, 4.3% were determined to be underweight, 25.2% were overweight, 15% were obese, and 53.1% had abdominal obesity. With age, the prevalence of both excessive body mass and abdominal obesity tended to increase, and that of underweight to decrease. Frequency of hypercholesterolemia and hypertriglyceridemia found in the whole group were 50% and 12.6% respectively, and also tended to rise with age. Low serum HDL-cholesterol (high density lipoprotein cholesterol) levels were found in 15.1% of the participants. Prevalence of impaired fasting glucose in the whole group was 8.2% and tended to increase with age. Diabetes was found in 1.2% of the participants and its prevalence also tended to rise with age, at the borderline of significance. Frequency of arterial hypertension and metabolic syndrome in the whole group was 15.7% and 14.1% respectively and both tended to increase with age.

CONCLUSIONS

Overweight and obesity, especially of abdominal type, and the related metabolic abnormalities are common in Polish women of childbearing age. Their prevalence tends to increase with age. Underweight is relatively common in the youngest age group.

Tobacco smoking in Poland in the years from 2003 to 2014. Multi‑centre National Population Health Examination Survey (WOBASZ)

INTRODUCTION    The reduction of tobacco smoking is a challenging problem of public health. OBJECTIVES    The main purpose of this work was to evaluate the prevalence and tobacco use patterns in the adult population of Poles and its changes in a period between year 2003 and 2014. Furthermore, changes in the smoking addiction, the declared reasons for smoking as well as readiness and motivation to stop smoking has been assessed.  PATIENTS AND METHODS    Based on data from the Polish studies - WOBASZ and WOBASZ II, the analysis covered a population of 14576 persons from the 1st study (6906 men and 7670 women) and 5696 persons from the 2nd study (2578 men and 3118 women), aged 20 - 74. RESULTS    According to the WOBASZ II study, in Poland 30% of men and 21% of women smoked,  the shares being 9 and 4 % lower for men and women respectively in comparison with the WOBASZ (p<0.001). The average number of cigarettes smoked daily per smoker significantly decreased in the period of observation among men (from 17.9 to 15.8 cigarettes/day) and women (from 13.7 to 12.1). The percentage of never smoking men rose from 29.8% to 36.1% (p<0.0001). The proportion of never smoking women no changed. However, the percentage of those expressing unwillingness to quit tobacco smoking nearly doubled in WOBASZ II vs WOBASZ. CONCLUSIONS    Although we found smoking rates in Poland have declined over the past decade, smoking remains prevalent among men and women. Therefore it is necessary to optimize the tobacco control in Poland including fiscal policy, counseling and tobacco addiction treatment, promotional and educational activities, with a special emphasis on the female population.

Prevalence of general and abdominal obesity and overweight among adults in Poland. Results of the WOBASZ II study (2013-2014) and comparison with the WOBASZ study (2003-2005)

INTRODUCTION There are limited data on the current prevalence of overweight and obesity as well as its changes with time in Poland. OBJECTIVES The aim of the study was to assess the prevalence of general and abdominal obesity and overweight in Polish adults in the years 2013-2014, and to compare it with the prevalence in the years 2003-2005. PATIENTS AND METHODS The study was conducted in 2 independent, representative samples of the Polish population, comprising 14 537 persons (aged 20-74 years) examined in the years 2003-2005 and 6164 persons (aged ≥20 years) examined in the years 2013-2014. Anthropometric measurements were done by trained nurses. RESULTS In the years 2013-2014, the age-standardized prevalence of obesity (body mass index [BMI] ≥30 kg/m2) was 24.4% in men and 25.0% in women. The prevalence of overweight (BMI, 25.0-29.9 kg/m2) was 43.2% in men and 30.5% in women. Abdominal obesity (waist circumference ≥102 cm in men or ≥88 cm in women) was noted in 32.2% of men and 45.7% of women. Abdominal overweight (waist circumference, 94-101.9 cm in men or 80-87.9 cm in women) was present in 27.2% of men and 21.7% of women. Since the years 2003-2005, the distribution of body mass according to the BMI category had shifted to higher values, and an increase in the prevalence of obesity was observed in men. The percentage of adults with normal waist circumference decreased significantly in both sexes. CONCLUSIONS Every fourth inhabitant of Poland is obese, and during the last decade, the prevalence of obesity has increased, particularly in men. Abdominal obesity is observed in every third man and nearly every second woman, and an excess of abdominal fat has increased in both sexes.

Multi-centre National Population Health Examination Survey (WOBASZ II study): assumptions, methods, and implementation

BACKGROUND

Cardiovascular diseases (CVDs) are the main cause of morbidity and mortality in developed countries. Despite the progress in diagnostics and treatment, it is expected that CVD will still be the main cause of death worldwide until at least 2030. From 1991 CVD mortality in Poland systematically decreased, but it is still higher than the average in Western Europe. In 2013 CVDs were the cause of 46% of all deaths in Poland (40.9% in men and 51.1% in women) and 26.9% of deaths among persons under 65 years of age. The epidemiologic assessment of prevalence, control and treatment of CVD risk factors, and monitoring of healthy behaviour and morbidity due to diseases like coronary artery disease, hypertension and diabetes is very important for health policy planning. The WOBASZ II is the newest Polish population based survey, performed in 2013-2014 to evaluate prevalence, control, treatment, and morbidity. The study was the continuation of WOBASZ (2003-2005).

AIM

To describe the goals and methods of the WOBASZ II study and to present the results of the recruitment.

METHODS

The WOBASZ II study was planned as a cross-sectional survey of a random sample of Polish residents aged over 20 years. The selection, using the National Identity Card Registry of the Ministry of Internal Affairs, was made as a three-stage sampling, stratified according to administrative units (voivodeships), type of urbanisation (commune), and gender. The study protocol consisted of a questionnaire used in face-to-face interviews, physical examination, and blood samples. WOBASZ II was coordinated by the Department of Epidemiology, Cardiovascular Diseases Prevention and Health Promotion of the Institute of Cardiology in Warsaw in cooperation with medical universities in Gdansk, Katowice, Krakow, Lodz, and Poznan.

RESULTS

Out of 15,120 persons, 1557 persons were not eligible. Out of eligible persons, 6170 (2760 men and 3410 women) were examined (the response rate 45.5%). The highest response rates were observed in Warminsko-Mazurskie (64.2%), Zachodniopomorskie (58.1%), and Kujawsko-Pomorskie (53.1%).

CONCLUSIONS

The importance of the WOBASZ study for the monitoring of the health state of Polish society, and for the as-sessment of prophylaxis efficiency and treatment of CVD and metabolic diseases, as well as for the evaluation of the actions in the field of health promotion, is difficult to overstate.
