A study of 544 patients with acute disorders of cerebral circulation demonstrated a correlation between the development of a stroke and the degree of alcohol abuse. In patients who abused alcoholic beverages acute disorders of cerebral circulation developed at a younger age, were much more acute and more frequently had a lethal outcome, especially if the stroke developed during acute alcoholic intoxication. The study also showed that in such cases hemorrhagical strokes were more common than ischemic.

The indices of total hamodynamics were studied in 52 patients with chronic alcoholism and without any clear signs of cardiac pathology and with normal arterial pressure. When examined at rest in a supine position they exhibited normal values of the cardiac and stroke index, peripheral vascular resistance, circulating blood volume and hematocrit. Along with the increasing period of alcohol abuse the cardiac index gets somewhat decreased, indicating a decreasing contractile capacity of the myocardium. This is further supported by the changing structure of the phases of the systole: prolongation of the phase of isometric contraction, of the tension phase, the tension index, reduction of the intrasystolic index and of the speed of intraventricular pressure increase. The orthostatic test revealed certain disorders in the regulation of the cardiovascular system in an upright position which manifested themselves in a more distinct, than in normal individuals, reduction of the cardiac and stroke indices, and in a more significant growth of cardiac contractions rate and peripheral vascular resistance. The latter indicates an increased mobilization of the sympathoadrenal system in an orthostatic position.

Seventy-eight patients with post-stroke seizures were studied retrospectively to determine the clinical, EEG and CT features of these seizures and their prognosis. There were 57 cerebral infarctions and 21 hemorrhages. Twenty-eight (36%) initial seizures occurred within one month after the stroke (0-24 hours in 19 cases) and were classified as early-onset seizures. Fifty (64%) initial seizures occurred more than 3 months after the stroke (3-12 months in 33 cases) and were classified as late-onset seizures. Compared with a population of 1938 strokes admitted during the same period, the proportion of patients with alcohol abuse, infarction in the anterior cerebral artery territory, watershed infarcts and lobar haemorrhages was significantly greater in our series. The proportion did not vary with the nature of the stroke (infarction or hemorrhage), except for early onset seizures in which the proportion of hemorrhages was significantly greater. Nor did it vary with the cause of hemispheric infarctions (cardioembolism or atherothrombosis or others). Ninety-five percent of the lesions affected the cerebral cortex or the subcortical white matter or both. Of all 78 initial seizures, 64% were partial motor (simple or secondarily generalized); 32% were primarily generalized, and 4% were partial not motor; status epilepticus was seen in 14% of the cases. An initial EEG, performed in 76 patients was normal in 7. Among the remaining 69 patients EEG showed focal or diffuse slowing down in 63% and epileptic features in 37% (including 10 cases of PLEDs). Early post-seizure EEG and repeated recordings significantly increased the specificity of EEG.(ABSTRACT TRUNCATED AT 250 WORDS)

Alcohol abuse is a frequent contributor to elevated blood pressure. 710 chronic alcoholics, aged 26-60 years, admitted for detoxification were studied. We compared hypertension prevalence in alcoholics with that in a similar group of non-alcoholics matched for age, sex, and miscellaneous diseases. The prevalence of hypertension was higher in heavy drinkers (11.4%) than in non drinker subjects (3.4%). Abstinence from alcohol during hospitalization was followed by normalization of hypertensive status in a high percentage of patients (70%). The majority of hypertensive alcoholics (75%) developed target organ damage ranging from retinopathy to hypertensive cardiomyopathy and renal lesion. In a 4.6 +/- 2.8 years follow-up study of 42 hypertensive alcoholic subjects, we observed that hypertension was 26% in those who abstained alcohol ingestion versus 84% in those who remained actively alcoholics. Four patients died of liver failure and two of stroke.

Based on the methods of the Brain Stroke Register, a study was made of epidemiology and risk factors (RF) of ischemic brain stroke (IBS) in one of the cities of the Middle Ob region, numbering 220 thousand population. Based on 615 cases of IBS, a noticeable rise of the disease incidence was revealed in a group of subjects aged 40-49 years as was a high level of the morbidity and mortality among persons over 60 years. Studies into RF discovered a high portion of arterial hypertension (75.1%), atherosclerosis (44.3%), aggravated heredity (28.6%), coronary heart disease (27.9%), alcohol abuse (17.9%). In 90.8% of cases, IBS developed in the presence of unfavorable fluctuations in atmospheric pressure, relative humidity, temperature, and the rate of air movement.

The extent of infarct area (IA) on CT-scan in 104 patients with ischemic stroke (IS) was compared with the presence of atrial fibrillation (AF) and other risk factors (hypertension, dyslipidemia, alcohol abuse). Infarct size was also compared with biological and clinical parameters in acute stage (6-12 h) (blood glucose level, systolic and diastolic arterial pressure, haematocrit, consciousness, clinical picture) and with clinical outcome. Among risk factors, only AF showed a significant correlation with IA extension (p less than .0009). IA correlated also with consciousness (p = .0017), clinical picture (p = .0145) and with clinical outcome (p less than 10(-6). Patients with AF showed a more severe clinical outcome with respect to patients without risk factors. It could be hypothesized that patients with AF have a reduced capacity for increasing or sustaining cerebral blood flow in the acute phase of IS.

Cocaine abuse is associated with a variety of severe acute neurologic complications. These include ischemic stroke, subarachnoid and intraparenchymal hemorrhage, syncope, seizures, and death. Eleven adult patients with cocaine-related seizures are reported. All were seen during the 1987 calendar year at the King/Drew Medical Center and Urban Comprehensive Epilepsy Program of Los Angeles. Three apparent clinical circumstances with defined methods of intake and time course after usage were identified in our cases. Seizures occurred 1) as acute provoked convulsions in patients known to have epilepsy, 2) spontaneously in otherwise normal individuals after acute snorting or "crack smoking," and 3) agonally with massive ingestion.

A total of 112 patients with ischemic stroke and 115 patients of different sexes and age with dyscirculatory encephalopathy were examined for the main risk factors of cardiovascular diseases. Hypokinesia and obesity were most common in chronic vascular brain pathology whereas frequently occurring and prolonged psychoemotional overstrain, aggravated heredity and alcohol abuse promoted the occurrence of acute disorders of brain circulation. The combination of 4 and more risk factors significantly raises the probability of acute cerebral ischemia.

Ethanol has long been recognized as a toxic agent that has acute and chronic effects on cerebral and hepatic function. Over the past two decades important influences on the cardiovascular system have been either rediscovered or observed for the first time. The combined use of tobacco cigarettes and alcohol appears to increase the risk of many of these clinical abnormalities. While many individuals addicted to ethanol have subclinical abnormalities of the heart, somewhat less than a majority develop symptomatic cardiac problems. These include heart failure and arrhythmias. In addition to supraventricular arrhythmias that often normalize spontaneously, there is an increased incidence of sudden death that peaks at about 50 years of age in the alcoholic population. A significant degree of blood pressure elevation occurs in individuals who abuse alcohol. This appears to be transient and is normalized in most individuals during abstinence. The increased incidence of hemorrhagic and nonhemorrhagic stroke in middle age also appears to decline when alcohol abuse is interrupted. A preventive effect of mild to moderate drinking on coronary artery disease is, at present, equivocal, largely due to the question of appropriate controls.

The impact, time trends and potential for prevention of premature deaths in Canada were assessed. There were almost 100,000 deaths before age 75 in Canada during 1986 resulting in over 1.7 million potential years of life lost (PYLL). The three leading broad disease categories responsible for PYLL were cancer, injuries/violence and cardiovascular disease. In both sexes, coronary heart disease, car accidents, lung cancer and perinatal conditions ranked in the top 5 specific diseases responsible for PYLL; breast cancer (females) and suicide (males) also ranked in the top 5 conditions. Over the period 1969 to 1986, death rates among persons less than age 75 increased for 3 conditions among females and 11 conditions among males. Lung cancer and brain cancer death rates increased in both sexes, chronic obstructive pulmonary disease death rates increased among females only and death rates for suicide and 8 types of cancer increased among males only. Over the same period, death rates declined for 37 discrete disease categories among both females and males including particularly large improvements for coronary heart disease, stroke, car accidents and perinatal conditions. An estimated 50,000 or over 50% of all premature deaths per year are preventable through control of smoking, hypertension, elevated serum cholesterol, diabetes and alcohol abuse. About 6,000 premature deaths are avoidable through improvements in medical care.
