Genetic investigation of fibromuscular dysplasia identifies risk loci and shared genetics with common cardiovascular diseases.

Fibromuscular dysplasia (FMD) is an arteriopathy associated with hypertension, stroke and myocardial infarction, affecting mostly women. We report results from the first genome-wide association meta-analysis of six studies including 1556 FMD cases and 7100 controls. We find an estimate of SNP-based heritability compatible with FMD having a polygenic basis, and report four robustly associated loci (PHACTR1, LRP1, ATP2B1, and LIMA1). Transcriptome-wide association analysis in arteries identifies one additional locus (SLC24A3). We characterize open chromatin in arterial primary cells and find that FMD associated variants are located in arterial-specific regulatory elements. Target genes are broadly involved in mechanisms related to actin cytoskeleton and intracellular calcium homeostasis, central to vascular contraction. We find significant genetic overlap between FMD and more common cardiovascular diseases and traits including blood pressure, migraine, intracranial aneurysm, and coronary artery disease.

Cardiovascular disease (CVD) risk factors in Kraków and in the whole Poland adult population. Results from the WOBASZ study and Polish arm of the HAPIEE project.

In Kraków, the second largest town in Poland, cardiovascular disease (CVD) mortality rate is lower than in most top largest towns in Poland and lower than the rate for total Polish population. AIM: The aim of the present analysis was to compare socioeconomic status (SES), prevalence of CVD risk factors and SCORE assessment of risk in Krakow with residents of other big towns in Poland and with general Polish population. MATERIALAND METHODS: We used data from the two large, population studies which used comparable methods for risk factors assessment: 1) Polish part of the HAPIEE Project in which 10 615 residents of Krakow at age between 45-69 years were examined, and (2) The WOBASZ Study which contributed with a sub-sample 6 888 of residents of Poland at corresponding age group. WOBASZ sample included 992 residents of big towns other than Krakow. Age-standardized proportions of persons with CVD risk factors were compared between Krakow and the other big towns in Poland and between Krakow and the whole Poland using χ2 test. RESULTS: The striking observation was that in Krakow proportions of participants with university education were substantially higher than average for the other big towns and the whole Poland. Also, the proportion of occupationally active men and women was the highest in Krakow. In both sexes, prevalence of smoking, hypercholesterolemia and hypertension in Krakow was similar to the other big towns but the prevalence of hypercholesterolemia and hypertension (in men only) was lower than average for Poland. The distribution by SCORE risk categories were similar in all three samples studied. In general, the distribution by BMI categories was less favourable but the prevalence of central obesity was lower among residents of Kraków than among residents of the other big towns and citizens of the whole Poland. Prevalence of diabetes was higher in Krakow than in the other samples studied. The differences between population of Krakow and population of other parts of Poland in the exposure to the main risk factors were found diverse and not big enough to be followed by differences in the distribution by the categories of SCORE risk assessment. The study suggested the importance of obesity and diabetes which are not used for the SCORE risk assessment and especially the importance of psychosocial and economic factors which may influence CVD risk and contribute more to the explanation of the regional differences in CVD mortality.

Is level of social support associated with health behaviours modifying cardiovascular risk? Results of the WOBASZ study.

BACKGROUND: Psychosocial risk factors affected the human health both by autonomic, neuroendocrine and immunological mechanisms and by the influence on human lifestyle. Lack of social support can reflect the person's lifestyle to more unhealthy. AIM: To assess if low, compared to high social support level (SSL), contributes to the unhealthy lifestyle in Polish general population. METHODS: The random sample of Polish population of 6164 men and 6915 women, aged 20-74, filled-in the Berkman and Syme questionnaire in 2003-2005 in the frame of National Multicenter Health Survey (WOBASZ). RESULTS: 31% of men and 39% of women had low SSL and they more often had high cardiovascular risk, depressive symptoms and cardiovascular disease risk factors, especially women. Men and women with low SSL more often smoked cigarettes than those with high SSL, rarely try to quit smoking, made regular physical activity, and rarely self-measured their blood pressure. Additionally men more often drank alcohol ≥ 30.0 g/day. They also more often did not take the prescribed medication, although they bought them. Out of unhealthy elements, lack of regular physical activity and blood pressure self-measuring were significantly and independently associated with SSL in both genders and additionally smoking habit and lack of quit smoking in the past in women. CONCLUSIONS: Persons with low SSL had more unhealthy lifestyle than those without. In Polish population the low SSL played a greater role in creating the cardiovascular risk in women than in men.

Do depressive symptoms adversely affect the lifestyle? Results of the WOBASZ study.

BACKGROUND: The negative psychosocial risk factors for cardiovascular (CV) disease, such as low social support or depression, may adversely affect the lifestyle. AIM: To evaluate the lifestyle in terms of anti-health behaviours in patients with depressive symptoms (DS) compared to individuals without DS. METHODS: A total of 6392 men and 7153 women aged 20-74 years were evaluated in the WOBASZ study [a multicentre nationwide study of the Polish population's health]). The presence of DS was assessed with Beck's Depression Inventory (BDI). Depressive symptoms were considered to be present if the patient scored at least 10 points on the BDI scale. RESULTS: The DS were present in 24% of men and 34% of women. In both groups, the mean age of subjects with DS was significantly higher compared to healthy individuals. Compared to healthy individuals, subjects with DS had a more unfavourable CV risk profile (hypertension, diabetes mellitus, obesity and hyperlipidaemia were significantly more prevalent among the subjects with DS), were characterised by a lower socioeconomic status and inhabited small administrative districts. Subjects with DS were also characterised by more anti-health lifestyles than healthy individuals. Of the 6 elements of anti-healthy lifestyle, 3 or more were observed in 18.8% of men with DS and 14.6% of men without DS (p < 0.0001) and in 17.5% of women with DS and 11.3% of women without DS (p < 0.0001). Significantly more men and women with DS than men and women without DS were regular smokers (men [M]: 42.3% vs 37.4%, p < 0.0007; women [W]: 25.6% vs 23.3%, p < 0.0346), were not physically active (M: 37.4% vs 30.2%, p < 0.0001; W: 43.4% vs 34.9%, p < 0.0001), consumed alcohol at least three times a week (M: 3.8% vs 1.7%, p < 0.0097; W: 0.3% vs 0.1%, p = 0.0349), were incompliant with their doctor's recommendations (M: 17.9% vs 12.3%, p < 0.0001; W: 22.2% vs 13.9%, p < 0.0001) and failed to have their blood pressure measured within the past year (M: 19.4% vs 15.0%, p < 0.0003; W: 15.1% vs 11.4%, p < 0.0001). The lack of physical activity and smoking, and - in women - regular consumption of alcohol, were demonstrated to be the lifestyle factors which were significantly and independently related to DS. CONCLUSIONS: A high prevalence of DS, especially among women, has been observed in the Polish population. The DS were found in every fourth man and every third woman. In both groups, subjects with DS were characterised by more anti-health lifestyle compared to healthy individuals. Of all the analysed factors of anti-health lifestyle the following were significantly and independently associated with DS - lack of physical activity and smoking in both sexes and, additionally, regular alcohol consumption in women.

Screening for major cardiovascular risk factors among Members of Polish Parliament as a continuation of health marketing for effective cardiovascular prevention in Poland. Warsaw, May 2006.

BACKGROUND: Cardiovascular diseases are the most common cause of mortality in Poland. To improve the situation in this area, a national cardiovascular preventive project is necessary, and it can be done by close cooperation between medical and political agencies. AIM: To present the current epidemiological situation in Poland to political and key opinion leaders and also to assess individual cardiovascular risk among Members of Polish Parliament. METHODS: The Project was carried out on 23-24 May 2006 in the residence of the Polish Parliament. Anthropometric, blood pressure and cholesterol measurements and a short questionnaire were performed. RESULTS: Survey and educational programme were carried out on 310 out of 460 Members of the Polish Parliament (females 59, males 251). Awareness of one's own blood pressure was declared by 70% of subjects, 39% declared earlier detected arterial hypertension, 21% had new detected elevated blood pressure, 31% declared earlier detected elevated cholesterol level and 32% had new detected elevated cholesterol level. Obesity was found in 40%, smoking was declared by 16.5%. The results were compared with those obtained in corresponding age-groups in the general population. CONCLUSIONS: 1. The results of screening survey in the Polish Parliament in 2006 indicate that, in comparison with nationwide adult population and Parliament Members examined in the year of 2000, present Parliament Members are more often diagnosed with obesity. However, they present with a better awareness of their own blood pressure and better control of arterial hypertension, as well as much lower percentage of those who admit smoking cigarettes. 2. Drawing Parliament Members attention to the problem of high prevalence and insufficient control of cardiovascular risk factors should result in positive outcome of future legislation process and make the battle with the epidemic of heart attacks and strokes in Poland more successful.

Characterization of insomnia in patients with essential hypertension.

INTRODUCTION: Insomnia may increase risk of cardiovascular events. There is little data available reporting the prevalence and clinical relevance of insomnia in patients with essential hypertension. Therefore, the aim of the study was to investigate the relationship between insomnia and different clinical and biochemical parameters in essential hypertension patients. METHODS: Four hundred and thirty-two patients (mean age 47+/-13 years; 253 male, 179 female) with essential hypertension were screened for insomnia using the athens Insomnia Scale (AIS). Several variables including age, sex, known duration of hypertension, body mass index, creatinine, left ventricular mass index, coexisting disorders, smoking status and alcohol use were analysed. Twenty-four-hour ambulatory blood pressure measurements (ABPM) were performed. RESULTS: Among patients included in the study, 207 subjects (mean age: 49+/-13 years; 47.9%) had an AIS score of 15 or higher and were identified as insomniacs. Insomnia was more frequent in women than in men (60.9% vs 38.7%, p<0.001) and was reported more frequently in patients with coronary artery disease. Subjects with insomnia were older and had longer duration of hypertension. There were no differences between insomniacs and non-insomniacs in ABPM parameters. A relationship was found between the number of antihypertensive drugs and insomnia frequency. There were correlation between AIS score and age (r=0.21; p<0.001) and duration of hypertension (r=0.22; p<0.001). In the sub-group of untreated essential hypertension patients, there were negative correlations between AIS score and night fall in systolic and diastolic blood pressure. CONCLUSION: Our results showed that insomnia is common in patients with essential hypertension and indicate an association between insomnia and gender, known duration of hypertension and number of hypertensive drugs taken. Untreated essential hypertension insomniacs were characterized by less pronounced nocturnal fall in both systolic and diastolic blood pressure compared with non-insomniacs.

How to improve cooperation with political leaders and other decision-makers to improve prevention of cardiovascular disease: lessons from Poland.

BACKGROUND: Cardiovascular diseases (CVD) are the main health problem in Poland. We decided to use modern social marketing methods to present the current epidemiological situation to political and key opinion leaders in Poland. MATERIALS AND METHODS: The surveys were carried out in the following groups: members of the Polish parliament, members of the executive bodies of the two largest trades unions in Poland, participants at the Polish Hygiene Society Congress, representatives of the health insurance board in the district of Pomerania, and press and radio journalists. The study consisted of a questionnaire, anthropometric measurements, blood pressure measurements, and cholesterol and glucose level tests. The results were presented to examined subjects individually and in the form of an educational conference held on the same day. RESULTS: In the examined groups of political and opinion leaders awareness of one's own blood pressure was declared by 40.6-86% of the subjects, increased blood pressure was found in 36-43.5%, overweight or obesity (body mass index 25 kg/m) in 40.6-67.3%, smoking was declared by 16.5-30%. The results were compared with those obtained in corresponding age groups in the general population. CONCLUSION: The idea of presenting the current epidemiological burden caused by CVD in Poland by means of an assessment of individual and collective CVD risk among political and opinion leaders appeared to be an effective method of education and constructive lobbying for the fight against an epidemic of myocardial infarctions and strokes in Poland.

Relationship between the prevalence of depressive symptoms and metabolic syndrome. Results of the SOPKARD Project.

INTRODUCTION: Depression is a newly recognised risk factor for ischaemic heart disease (IHD). The results of many studies show that depression may contribute to the development of components of metabolic syndrome, such as arterial hypertension, obesity and glycaemic abnormalities. Thus it may have a significant impact on IHD development and worsen the course of an already established disorder. AIM: Evaluation of the prevalence of metabolic syndrome and depression among Sopot inhabitants aged 50 or 60 years. METHODS: This study involved 795 consecutive inhabitants of Sopot (477 female and 318 male) who were invited in 2003 and 2004 to participate in screening examinations in the programme of primary prevention of arterial hypertension, diabetes and lipid abnormalities -- SOPKARD. Metabolic syndrome was diagnosed according to the NCEP ATP III guidelines. Beck's Depression Inventory was used for the assessment of depressive symptoms. RESULTS: Metabolic syndrome was recognised in 32% of participants (in 31% of women and in 33% of men). The distribution of particular elements of metabolic syndrome was as follows: elevated blood pressure was found in 63% of subjects (female -- 58%, male -- 70%), abnormal fasting glucose in 24% (female -- 21%, male -- 28%), visceral (abdominal) obesity in 33% (female -- 38%, male -- 26%), elevated triglyceride level in 34% (female - 28%, male - 42%) and decreased HDL level in 26% (female -- 28%, male -- 23%). Symptoms of depression were found in 37% of studied subjects (42% of females, 28% of males). Metabolic syndrome was observed more frequently in subjects with depressive symptoms compared to those without depressive symptoms in the whole group (35% vs 28%, p <0.05) and in males (44% vs 28%, p <.05). This difference was not statistically significant in females (31% vs 28%, ns). Visceral obesity was observed more frequently in males with depressive symptoms than in those without depressive symptoms (37% vs 21%, p <0.001). It was not observed in the whole group and in females. The studied females group with depression more often had a higher fasting serum glucose concentration when compared to those without depression (25% vs 18%, p<0.05). Such a relationship was not observed in the male group and whole group. CONCLUSIONS: In the studied group of middle-aged subjects, especially among women, a high prevalence of depression symptoms was noted. Statistically significant correlations between the prevalence of depressive symptoms and visceral obesity in men and an elevated glucose level in women were shown.
