The Rise and Fall of Hypertension: Lessons Learned from Eastern Europe

Hypertension is a progressive cardiovascular syndrome that arises from many differing, but interrelated, etiologies. Hypertension is the most prevalent cardiovascular disorder, affecting 20% to 50% of the adult population in developed countries. Arterial hypertension is a major risk factor for cardiovascular diseases and death. Epidemiologic data have shown that control of hypertension is achieved in only a small percentage of hypertensive patients. Findings from the World Health Organization project Monitoring Trends and Determinants in Cardiovascular Diseases (MONICA) showed a remarkably high prevalence (about 65%) of hypertension in Eastern Europeans. There is virtually no difference however, between the success rate in controlling hypertension when comparing Eastern and Western European populations. Diagnosing hypertension depends on both population awareness of the dangers of hypertension and medical interventions aimed at the detecting elevated blood pressure, even in asymptomatic patients. Medical compliance with guidelines for the treatment of hypertension is variable throughout Eastern Europe. Prevalence of hypertension increases with age, and the management of hypertension in elderly is a significant problem. The treatment of hypertension demands a comprehensive approach to the patient with regard to cardiovascular risk and individualization of hypertensive therapy

Higher prevalence of smoking and lower BMI, waist circumference, cholesterol and triacylglyceride levels in Prague's homeless compared to a majority of the Czech population

BACKGROUND: Homeless people have higher morbidity and mortality rates than the general population. Research has shown that cardiovascular disease is the leading cause of death in older homeless adults. This study was undertaken to describe the prevalence of cardiovascular risk factors in the homeless population in Prague. METHODS: Data was obtained from a cross-sectional study carried out in 2003. Body mass index (BMI), waist circumference (WC), total cholesterol (TC), triacylglycerides (TAG) and smoking habits were assessed. The homeless participants in the study were recruited from a homeless center run by a Prague charitable organization called Naděje ("Hope") and at Prague's main railway station. Most participants were assessed at the Naděje center (134 persons) while the rest were assessed at Prague's Bulovka University Hospital (67 persons). RESULTS: A total of 201 homeless (174 males and 27 females) aged 19 – 70 years were examined. Mean values of BMI, WC, TC and TAG in homeless men and women were within normal limits. Compared with the majority of the Czech population, the homeless had significantly lower mean levels of TC and TAG and lower BMI and WC values. When compared to the majority of the Czech population, the incidence of smoking among the homeless was significantly higher. Among smokers in both populations, no differences were found in the number of cigarettes smoked per day. CONCLUSION: Classical cardiovascular risk factors such as TC, TAG, BMI and WC, are significantly lower in Prague's homeless minority than in the majority of the Czech population. However, the prevalence of smoking is much higher in the homeless population

Cardiovascular disease, chronic kidney disease, and diabetes mortality burden of cardiometabolic risk factors from 1980 to 2010: a comparative risk assessment

Background High blood pressure, blood glucose, serum cholesterol, and BMI are risk factors for cardiovascular diseases and some of these factors also increase the risk of chronic kidney disease and diabetes. We estimated mortality from cardiovascular diseases, chronic kidney disease, and diabetes that was attributable to these four cardiometabolic risk factors for all countries and regions from 1980 to 2010. Methods We used data for exposure to risk factors by country, age group, and sex from pooled analyses of populationbased health surveys. We obtained relative risks for the eff ects of risk factors on cause-specifi c mortality from metaanalyses of large prospective studies. We calculated the population attributable fractions for- each risk factor alone, and for the combination of all risk factors, accounting for multicausality and for mediation of the eff ects of BMI by the other three risks. We calculated attributable deaths by multiplying the cause-specifi c population attributable fractions by the number of disease-specifi c deaths. We obtained cause-specifi c mortality from the Global Burden of Diseases, Injuries, and Risk Factors 2010 Study. We propagated the uncertainties of all the inputs to the fi nal estimates. Findings In 2010, high blood pressure was the leading risk factor for deaths due to cardiovascular diseases, chronic kidney disease, and diabetes in every region, causing more than 40% of worldwide deaths from these diseases; high BMI and glucose were each responsible for about 15% of deaths, and high cholesterol for more than 10%. After accounting for multicausality, 63% (10\ub78 million deaths, 95% CI 10\ub71\u201311\ub75) of deaths from these diseases in 2010 were attributable to the combined eff ect of these four metabolic risk factors, compared with 67% (7\ub71 million deaths, 6\ub76\u20137\ub76) in 1980. The mortality burden of high BMI and glucose nearly doubled from 1980 to 2010. At the country level, age-standardised death rates from these diseases attributable to the combined eff ects of these four risk factors surpassed 925 deaths per 100 000 for men in Belarus, Kazakhstan, and Mongolia, but were less than 130 deaths per 100 000 for women and less than 200 for men in some high-income countries including Australia, Canada, France, Japan, the Netherlands, Singapore, South Korea, and Spain. Interpretation The salient features of the cardiometabolic disease and risk factor epidemic at the beginning of the 21st century are high blood pressure and an increasing eff ect of obesity and diabetes. The mortality burden of cardiometabolic risk factors has shifted from high-income to low-income and middle-income countries. Lowering cardiometabolic risks through dietary, behavioural, and pharmacological interventions should be a part of the globalresponse to non-communicable diseases

Original Article Why We Are Not Able to Find the Coronary Heart Disease Gene -apoE As an Example (apoprotein E / cardiovascular risk /gene polymorphism / myocardial infarction)

Abstract. The apoprotein E gene ranks among the most discussed candidate genes for cardiovascular disease. We studied whether the association between apoprotein E gene polymorphism and manifestation of acute coronary syndrome is modulated by the presence/absence of traditional cardiovascular risk factors. The population under study were 1066 patients (men under 65 years) admitted between 2006-2009 to five coronary care units in Prague (GENetic DEtermination of Myocardial Infarction in Prague) and the control population (1066 age-matched men selected from the Czech population sample). The frequency of disadvantage genotype E4 + was significantly higher (P < 0.01) in acute coronary syndrome patients (22.38 %) than in controls (16.76 %). When the acute coronary syndrome group was step by step limited to non-smokers, non-diabetics and normotensive individuals, the odds ratio displayed a gradual increase from 1.35 (for the entire group) through 1.48 (non-smokers), 1.53 (non-smokers+non-diabetics) to 1.71 (non-smokers+non-diabetics+normoten-sives). The effect of the apoprotein E gene on the individual risk of acute coronary syndrome is nonhomogenous within the patient groups. This association of apoprotein E gene with acute coronary syndrome is strongly modified by the presence/absence of traditional cardiovascular factors of atherosclerosis in a high-risk Czech population
