Unsaturated fat and cardiovascular health in Poland
The 1990s have seen a rapid transformation in cardiovascular health in Poland, including in morbidity and mortality from coronary heart disease (CHD). The causes of this phenomenon were multifactorial. However, in the case of Poland it has been proposed that perhaps the most important mechanisms were changes in the diet, and particularly in the rapid transformation of the structure of fat consumption between 1980s and 1990s, which were triggered by profound social, political and economic changes. In result of these, the Polish diet begun developing towards a Mediterranean style, and included biologically important changes concerning dietary cardio-protective modifications. Specifically, it has been suggested that initially the countries of Central and Eastern European region, including Poland, had experienced deficiency in polyunsaturated fatty acids, especially alpha-linolenic acid, which was then levelled up in Poland at the beginning of 1990s, and which resulted in cardiovascular transformation. This article outlines the key milestones observed in the transformation of diet in Poland between 1950s and 1990s, and offers an overview of the possible contribution it had on the improvements in CHD.
Rapid Drop in Coronary Heart Disease Mortality in Czech Male Population—What Was Actually behind It?
Biomedicines
The high mortality of coronary heart disease (CHD) among Czech men—one of the highest worldwide—began to decline in 1991 soon after the abolition of government subsidies to all foodstuffs rich in animal fat. As participants in the WHO MONICA Project, we were able to analyze the CHD risk factors just before and after this major economic change. We had previously documented that the originally subsidized prices decreased animal fat consumption and consequently non-HDL cholesterol concentrations in the population. By the early 1990s, no progress had been made in the treatment of acute myocardial infarction, statins were unavailable as was not the currently more effective antihypertensive therapy. Our recent research proved a close relationship between cholesterolemia and proinflammatory macrophages in adipose tissue and accelerated macrophage polarization with increased palmitate and palmitoleate contents in cell membrane phospholipids. By contrast, the proportion of proinflammatory ma...

Aims: This study investigated the trends and levels of the prevalence of health factors, and the association of all-cause and cardiovascular (CVD) mortality with healthy levels of combined risk factors among Lithuanian urban population. Methods: Data from five general population surveys in Kaunas, Lithuania, conducted between 1983 and 2008 were used. Healthy factors measured at baseline include non-smoking, normal weight, normal arterial blood pressure, normal level of total serum cholesterol, normal physical activity and normal level of fasting glucose. Among 9,209 men and women aged 45-64 (7,648 were free from coronary heart disease (CHD) and stroke at baseline), 1,219 death cases from any cause, 589 deaths from CVD, and 342 deaths from CHD occurred during follow up. Cox proportional hazards regression was used to estimate the association between health factors and mortality from all causes, CVD and CHD. Results: Between 1983 and 2008, the proportion of subjects with 6 healthy levels of risk factors was higher in 2006-2008 than in 1983-1984 (0.6% vs. 0.2%; p50.09), although there was a significant increase in fasting glucose and a decline in intermediate physical activity. Men and women with normal or intermediate levels of risk factors had significantly lower all-cause, CVD and CHD mortality risk than persons with high levels of risk factors. Subjects with 5-6 healthy factors had hazard ratio (HR) of CVD mortality 0.35 (95% confidence interval (CI) 0.15-0.83) compared to average risk in the whole population. The hazard ratio for CVD mortality risk was significant in men (HR 0.34, 95% CI 0.12-0.97) but not in women (HR 0.38, 95% CI 0.09-1.67).
High-risk profile in a region with extremely elevated cardiovascular mortality
Hellenic journal of cardiology : HJC = Hellēnikē kardiologikē epitheōrēsē
Although mortality rates from cardiovascular diseases have shown a remarkable decline in many western countries, cardiovascular mortality in Lithuania has remained high. It is widely accepted that half of the decline in cardiovascular mortality can be attributed to favourable changes in modifiable risk factors. In 2006, the Lithuanian High Cardiovascular Risk Programme was started. A two-level approach--primary health care institutions and specialised cardiovascular prevention units--was applied. The cardiovascular risk profile was evaluated for a group of 17,031 middle-aged subjects enrolled into the programme at a primary level and 2908 at a specialised level. Among the persons examined, 61.8% (10,519) were female. Arterial hypertension was present in 60.2% of the subjects. Dyslipidaemia was present in 88.8%. Total cholesterol was 6.02 ± 1.23 mmol/L, LDL cholesterol 3.74 ± 1.09 mmol/L, HDL cholesterol 1.53 ± 0.52 mmol/L, and triglycerides 1.61 ± 1.27 mmol/L. Diabetes mellitus was ...
A population-based cross-sectional study of cardiovascular risk factor in Latvia
Medicina (Kaunas, Lithuania), 2012
To date, the epidemiological studies of noncommunicable diseases in Latvia were more episodic and covered only selected areas. The first national cross-sectional population-based survey of cardiovascular risk factors after regaining independence was carried out to provide reliable information on the cardiovascular risk factor profile in adults. Computerized random sampling from the Registry of Latvian population was carried out. A total of 6000 enrolled subjects aged 25-74 years were divided into 10 age subgroups. The data of 3807 respondents (63.5% of all) were included into the final analysis. The mean number of cardiovascular risk factors was 2.99±0.026 per subject: 3.45±0.043 and 2.72±0.030 for men and women, respectively. Of all the respondents, 75.2% had an increased total cholesterol level. Hypercholesterolemia was found in almost 56% of men and 41% of women in the age group of 25-34 years. Hyperglycemia was documented in 34.1% of the respondents (41.6% of men and 29.8% of wo...

Since the beginning of the 1990s the public health situation in Russia has been characterized by an extremely high mortality and a significant reduction in life expectancy. Cardiovascular diseases remained the major cause of death. Only a few large population studies were conducted in Russia during this period. A total of 1968 men and 1737 women aged 18-75 years participated in a health survey in Arkhangelsk, Russia, over the period 1999-2000. Investigation included assessment of classic cardiovascular risk factors (family history, smoking, blood pressure, and blood lipids) along with general health variables. The paper presents sex specific data on risk factors for coronary heart disease. Though the cardiovascular mortality is high in Russia, the calculated risk for coronary heart disease (the Framingham risk score and the Norwegian risk score) was lower in all age groups of men and women in Arkhangelsk compared with studies from the Western Europe and USA. Our data suggest that hi...
Decline in mortality from coronary heart disease in Finland from 1969 to 1979
BMJ, 1983
Objectives To examine how much of the observed rapid decrease in mortality from coronary heart disease in Poland after the political, social, and economic transformation in the early 1990s could be explained by the use of medical and surgical treatments and how much by changes in cardiovascular risk factors.

The purpose of this manuscript is to examine changes in blood lipid levels and related factors between 1983 and 1987 in two selected Polish populations, to evaluate these changes and their association with other coronary heart disease (CHD) risk factors, and to examine the nutrient intake changes for consistency with observed lipid changes. METHODS: Men and women, aged 35-64 were screened from Warsaw and rural Tarnobraeg province, Poland-the Pol-MONICA screening sites. An independent random sample of 5 132 screened in 1983-84 and a second independent random sample of 2596 screened in 1987-88 were compared. A 25% cohort of the 1983-84 sample was also rescreened in 1987-88 (n = 1236) and 24-h our dietary recall information on this cohort was used to evaluate nutrient intake changes and their relationship to the lipid changes. RESULTS: For the random samples, the total cholesterol increased by 5.1 mg/dL (rural) and by 7.9 mgldL (urban) for women; there were no significant changes among men. Low-density lipoprercexn cholesterol (LDL-C) increased for all site and gender subgroups by 5.4-8.7 mg/dL. Among rural men and women, high-density lipoprotein cholesterol (HDL-C) d ecreased by 3.4 and 3.3 mg/dL, respectively, whereas it increased by 3.3 mg/dL among urban women and did not change among urban men. Total triglycerides (TG) increased by 9.5 mg/dL for rural men, with no significant change for rural women. For urban men and women, TG decreased by 29.5 and 21.8 mg/dL respectively. In the cohort, changes in dietary intake (decreases in energy from fat, Keys index and increases in the polyunsaturated ro saturared fats ratio) were related to a decrease in TC at both sites and to a decrease or smaller increi3.z in LDL-C for rural men. CONCLUSIONS: The observed changes were generally unfavorable, with a decrease in the proportton of persons with desirable lipid levels. At both sites nutritional changes were favorable, including a drop in total energy intake. Less pronounced were changes in percentages of total energy from fats, whcrr the only significant decrease was for rural women; however, improvements in dietary fat composition and declines in cholesterol consumption were found. These favorable changes in diet were not strong rnough or were not in effect long enough to counter the unfavorable changes in blood lipids.
