Alcohol abuse is a substantial public health problem, resulting in staggering financial costs and other burdens. Prolonged alcohol abuse leads to cardiomyopathy in a minority of alcohol abusers, but because alcoholism is so widespread, alcohol is the major cause of nonischemic cardiomyopathy in Western society. In contrast, substantial evidence now suggests that moderate alcohol consumption has cardioprotective effects. It not only reduces the incidence of fatal ischemic heart disease, but it improves outcome in patients who have other risks for coronary events and go on to have myocardial infarctions. Therefore, physicians' recommendations about alcohol consumption should be as individualized as their patients.

The growing size of world cities and ever more competitive working conditions are thought to cause subjective stress, anxiety and depression, with a resulting decrease in the quality of life, sleep disturbances, drug and alcohol abuse and poor productivity. Acute stress may suppress immune function, leading to an increased incidence of infections, and chronic stress may predispose to a number of ailments, including digestive disturbances, hypertension, ischaemic heart disease and neoplasia; jointly, these factors cause a substantial shortening of life expectancy. The control of stress thus makes an important contribution to health. Stress levels can be reduced by anxiolytic drugs, or by a variety of psychological techniques; however, an appropriate programme of physical activity may be the preferred option, since exercise has many positive effects on health that are unrelated to stress. If exercise is to be effective in inducing relaxation, it must be noncompetitive, moderate in intensity, and pursued in pleasant surroundings.

To understand more fully the nature of events leading to asthmatic death, we conducted a confidential enquiry prospectively throughout 1994-96 among the surviving relatives and respective general practitioners of subjects whose deaths could be attributed to asthma, whether wholly or partly. We also reviewed relevant hospital records and autopsy reports, and we submitted all the gathered information to an enquiry panel for evaluation. The subjects were identified from death certificates issued in five districts of the Northern Health Region of England (population 1 million) on which asthma was recorded as the primary cause of death. The enquiry panel agreed that asthma had been a critical factor in causing death in only 33 of the 79 certified cases for which there were sufficient data. The level of concordance was substantially greater for subjects aged < 65 years (76%) than for those who were older (17%). In 16 of the 33 cases asthma alone appeared to be responsible for death, but in 17 cases a wide variety of additional, co-morbid, disorders appeared to have contributed. They included, during the 24 h preceding death, gastric aspiration, septicaemia, a single dose of a beta-blocker, the abuse of organic solvents or illicit drugs and possibly, an inadvertent exposure to horse allergen. More chronic causes of co-morbidity included ischaemic heart disease, chronic obstructive pulmonary disease (COPD), thoracic cage deformity and alcohol abuse. There were possible errors of judgement in two cases by the supervising physician (6%) and in three cases by the patient (9%). Poor compliance and psychosocial disruption probably exerted an additional adverse influence in nine cases (27%). We conclude: (1) that asthma death certification in subjects aged 65 years or more is very unreliable, (2) that for approximately half of the deaths in which asthma exerted a critical role there were critical co-morbid disorders and (3) that errors of judgement, poor compliance, or psychosocial disruption are likely to have exerted an additional adverse influence in an important minority of cases.

Moderate ethanol consumption (1-3 drinks/day on 5-6 days/week) has a favourable effect on vascular disease-related mortality and morbidity [especially ischaemic heart disease (IHD)]. This cardioprotective effect may be due to significant effects on cardiovascular risk factors such as high density cholesterol (HDL) concentration (HDL protects from IHD) and an inhibition of platelet aggregation (increased platelet aggregability predicts coronary events). In contrast, alcoholics and problem drinkers have an excess of IHD-related, and possibly stroke-related, mortality. Excessive alcohol intake may raise the blood pressure. Prolonged alcohol abuse can also result in alcoholic heart muscle disease. Alcohol is the major cause of non-ischaemic cardiomyopathy in Western society. Although there is a widespread belief that red wine protects more than other alcoholic beverages, several studies do not support this interpretation.

The risk of ischemic heart disease is connected with the definite mode of life. Improper nourishment, smoking, alcohol abuse, sedentary lifestyle and excessive mental stress cause disturbances leading to development of atherosclerosis. The change of the lifestyle may prevent from coronary heart disease and may play a main role in secondary prevention, making the prognosis after myocardial infarction much better. The epidemiological and clinical studies have shown the significance of particular risk factors reduction on survival after myocardial infarction and allowed to create the optimal preventive mode of life. Therefore the change of lifestyle should become the priority in the postinfarction therapy.

In 2,000 consecutive stroke patients collected in a prospective hospital-based stroke registry over a 10-year period, we assessed whether stroke in men and women was different in respect to vascular risk factors, clinical features and natural history. The frequency of the different variable in men and women was analyzed by means of univariate analysis and logistic regression models. Women accounted for 48% of the study population (n = 967) and were older than men (mean age 75 vs. 69 years, p < 0.001). In the age group of 85 years or older, stroke was more frequent in women than in men (69.8 vs. 30.2%, p < 0.001). Women showed a higher frequency of cardioembolic infarction and a lower occurrence of lacunar infarction and stroke of undetermined cause than men. In-hospital mortality (17.4 vs. 13.3%) and length of hospital stay (19.6 vs. 16.7 days) was significantly higher (p < 0.001) in women than in men. In the model based on demographic variables and cardiovascular risk factors, obesity, heart failure, atrial fibrillation and age were significant predictors of stroke in women, while intermittent claudication, ischemic heart disease, chronic obstructive pulmonary disease, cigarette smoking and alcohol abuse were predictors in male sex. Hypertension and limb weakness were predictors for stroke in women, and absence of neurological deficit at hospital discharge, lacunar syndrome and ataxia were predictors in men in the models based on all variables. Women differ from men in the distribution of risk factors and stroke subtype, stroke severity and outcome. Differences in stroke pathology and/or differences in functional anatomy or plasticity of the brain between sexes may account for these findings.

In the transition period from a communist to market-oriented economy, Bulgaria faces several public health challenges. One of them is the decline in population (estimated fall from current 8.25 million to around 6 million in 2045), mainly due to emigration and pronounced fall in fertility. Infant mortality is still relatively high (over 15/1,000 live births), and the incidence of tuberculosis is on the rise. Total mortality shows a steady upward trend from 12.1/1,000 in 1990 to 14.3/1,000 in 1998. Trends in ischemic heart disease are comparable to those in other Central and Eastern European countries, but stroke mortality is notably higher. This calls for detailed epidemiological studies of risk factors, such as salt consumption, as well as preventive programs for detection and control of high blood pressure. The problems of smoking and alcohol abuse should be addressed by a coordinated public health and legal measures.

Several international studies from Spain, the Netherlands, Poland, Croatia, and Finland indicate contradicting findings regarding cardiovascular dysfunction among seamen, deep sea fishermen, and harbor workers. The purpose of the present survey was to evaluate the prevalence of hypertension in a selected group of Lithuanian seamen. The survey was conducted during a one year period and involved sailors from commercial, passenger, and fishing boats. The survey took into account the sailors' marital status, education, professional rank and duty, and length of stay at sea. It also included demographical data, complete family health history, the sailor's awareness about their health in general, and awareness about their blood pressure in particular. Their dietary habits, changes in body weight, the history of alcohol intake and tobacco usage were also recorded. Analysis of our data indicates that 44.9% of Lithuanian mariners suffer from a clinically significant elevation of blood pressure, as compared to 53% of the general population of Lithuania. Some of the leading risk factors are: a high cholesterol diet and increased body mass index (BMI), smoking, alcohol abuse, family situation and level of education. The high prevalence of the cardiovascular risk factors was to be found related to ischemic heart disease and cerebrovascular illness. This may be influenced by poor eating habits, poor health awareness and other social and environmental factors which are common to seamen. Increased blood pressure is a widespread condition that affects a large portion of the population in developed countries. It is an important risk factor for cardiovascular and cerebrovascular disease, as well as a significant preventable cause of mortality. According to the World Health Organization (WHO), hypertension is a risk factor for cardiovascular disease, which accounts for an estimated 17 million deaths each year. With hypertension, the risk of stroke increases 2.6-3.8 times, the risk of ischemic heart disease (IHD)--2.0-2.2 times, and that of congestive heart failure (CHF)--3.0-4.0 times. Hypertension is often accompanied by other cardiovascular risk factors such as dyslipidemia, smoking, diabetes and increased body mass index (BMI). When hypertension is present in conjunction with other risk factors, the risk of mortality associated with IHD can increase tenfold. On the other hand, risk factors such as an increased BMI, smoking, alcohol abuse, lack of exercise and a diet high in salt and fatty foods can themselves play an instrumental role in the etiology of hypertension. Several studies have been performed on the prevalence of hypertension among the general population in Lithuania, which is higher than that of most other European countries. Reviews performed by the programs CINDI (Countrywide Integrated Noncommunicable Disease Intervention) and MONICA (MONItoring CArdiovascular Disease) determined that about half of all studied persons of middle age in Lithuania were hypertensive. Our work is the first study seeking to examine the prevalence of hypertension among Lithuanian seamen, as well as its association with various risk factors and dependence on demographic indices.

A 65-year-old man with known ischemic heart disease and previous coronary artery bypass grafts was admitted having been found collapsed in the street. He was a smoker with a history of alcohol abuse. On clinical examination he was unkempt, febrile, hemodynamically stable, and had no systemic deficits. The O2 saturation on air was 99%, with a po2 of 9.2, and pco2 of 4.0. Ventilation perfusion (VQ) scan was performed to rule out a pulmonary embolism. While in the department he was noted to be dyspneic and generally unwell. The perfusion images showed reduced perfusion to both lower zones more marked on the right. The ventilation study was markedly abnormal on the initial views with no ventilation to the right lung. However, the patient had recurrent episodes of cough with expectoration of sputum before the anterior view was imaged, which subsequently demonstrated ventilation defects in the right mid and lower zones. A repeat ventilation sequence was performed which confirmed these findings in all views. Chest x-ray performed prior to the lung scan was normal.

The effects of alcoholic beverages on the cardiovascular system can take opposite forms, depending on how much of ethanol is consumed. The negative effects of alcoholism are well established. Alcoholism is a cause of cardiomyopathy, cardiac arrhythmias and hypertension. The best argument is the situation of Russian Federation where extremely high alcohol consumption caused very high ischemic heart disease and stroke mortality both in male and female population. On the other side there are also many proofs of health benefits of moderate alcohol consumption. The National Institute on Alcohol Abuse and Alcoholism in USA has completed an extensive review of current scientific knowledge about the health effects of moderate alcohol consumption: the lowest death rate from all causes occurs at the level of one drink per day. Moderate drinkers have the greatest longevity. Higher serum levels of high density lipoproteins (HDL) in moderate alcohol drinkers are associated with reduced risk for the development of atherosclerotic disease. HDL particles are believed to be antiatherogenic due to their capacity to drive reverse cholesterol transport and to antagonize pathways of inflammation, thrombosis, and oxidation (Fig. 4, Ref. 34).
