The relative extent of raised and calcified coronary aortic lesions, prevalence of coronary stenosis and of fresh and old myocardial infarction, and mean heart weight were expressed on a continuous scale for 4 disease groups (coronary heart disease, cerebral infarction/haemorrhage, hypertension/diabetes, cancer). Within these groups the relative position for each of the lesions was calculated by subgroups of disease in order to show the elevating or depressing effect of hypertension, diabetes, obesity, and combinations of disease. The strength of association between 33 factors (town 5, disease 24, obesity, heart weight, age, and sex) and the lesions was calculated. An analysis of variance was carried out and the proportion of the variance of the different lesions accounted for by town, disease, etc., is shown. The extent of raised aortic lesions is strongly associated with age and hypertension. It is positively associated with coronary heart disease and inversely associated with cancer. Town factors have a small positive association which is larger than that due to obesity. 33 factors taken together account for 50% of the variance. Age alone accounts for 37% and sex for only 0.3%. The extent of calcified aortic lesion is strongly associated with age, town, hypertension, coronary heart disease and diabetes mellitus. It is inversely associated with cancer, more strongly in cancer of the bronchus and the liver than in other cancers. It is inversely associated with obesity. 33 factors together account for 30% of the variance and age alone accounts for about 13%. The extent of raised coronary lesions is strongly associated with age, coronary heart disease, sex, diabetes mellitus, hypertension and obesity. It is inversely associated with cancer, more strongly in cancer of the prostate and the liver than in other cancers. Town factors have a small association. 33 factors taken together account for about 43% of the variance. Age alone accounts for 25%. The extent of calcified coronary lesions is associated with coronary heart disease and age. There is a low association with hypertension and diabetes, an inverse association with cancer, and a low inverse association with obesity. 33 factors together account for 20% of the variance. Coronary heart disease alone accounts for 12% and age alone accounts for 8%. The prevalence of coronary stenosis is strongly associated with coronary heart disease, age, and sex. There is a small association with town factors, obesity, and hypertension, and an inverse association with cancer. All the factors together account for about 30% of the variance. Coronary heart disease alone accounts for 23% and age 10%.

1. There were significant correlation between hyperlipidemia and obesity, hypertension, abnormal ECG and abnormal eyeground. 2. The incidence of cerebral hemorrhage was closely associated with hypertension but not with hyperlipidemia. 3. It was proved that hypertension with both hyper-Ch and hyper-TG was highly related to the development of cerebral infarction. 4. It seemed that the incidence of myocardial infarction and angina pectoris was related to hypertension with hyper-Ch. 5. Therefore, the present study suggested that the control of hypercholesterolemia and hypertriglyceridemia was useful for the prevention of cerebro-cardiovascular disease.

1) In 113 patients with cerebral infarction, the cause of infarction was cardiac embolism in 35, atherosclerotic thromboembolism in 45. It was either cardiac embolism or atherosclerosis but undetermined in 30. 2) Seven risk factors have been analysed. Eight patients (7 p.cent) had none of these factors. In the 105 remaining patients risk factors were: a) atrial fibrillation in 36, diagnosed in 21. Efficient treatment was applied in 1 or perhaps in 2 patients; b) High blood pressure in 39, diagnosed in 32, efficiently treated in 5; c) dyslipidemia in 42, diagnosed in 9, efficiently treated in 3; d) obesity in 50, efficiently tackled in 2; e) diabetes in 24, diagnosed in 11, efficiently treated in 2; f) hyperuricemia in 28, diagnosed in 1 with no efficient treatment; g) smoking in 44, abandonned by 1 only. 3) The high frequency of cardiac embolism is briefly commented. 4) Non diagnosis or unefficient treatment was present in a high proportion of cases. Realizing this regrettable state of affairs should result in better preventive diagnosis and treatment which, is assumed, could significantly reduce cerebral infarction.

The role of alcohol as a risk factor for cerebral infarction and hemorrhage has been assesed in 200 middle-aged and elderly stroke patients and 200 controls matched for age, sex and hospital admission date. Computed tomographic brain scans were done in all but 10 of the stroke patients. Alcohol intake was reckoned on the 12 months preceding hospitalization and expressed in grams daily according to a standard nomogram. The Michigan Alcoholism Screening Test was used for the diagnosis of alcoholism. Cerebral infarction was present in 59% of the stroke patients and cerebral hemorrhage in 9%. The role of alcohol as risk factor for stroke proved to be small (Odds Ratio 1.86) and was practically lost after adjustment for the most common risk factors for cerebrovascular disorders (previous strokes, arterial hypertension, diabetes, obesity and hyperlipidemia). Our findings seem to suggest that alcohol is not an independent risk factor for stroke in the middle-aged and elderly. The data are, however, preliminary and are discussed in the light of methological problems.

Cardiovascular disease is the third most common cause of death in Tshepong Hospital in the western Transvaal, and the most common cause of death in patients older than 35 years. A prospective study was undertaken which included limited necropsies in 90 of the 167 cardiovascular disease deaths over 1 year. A reliable mortality pattern for cardiovascular deaths is described. Additionally, attention is paid to co-existing conditions. Conditions relating to cardiovascular disease, such as hypertension, benign hypertensive nephrosclerosis, atherosclerosis and obesity, were also evaluated. Cerebrovascular conditions were found in 32% of cardiovascular deaths. Intracerebral haemorrhage was found in 50% and cerebral infarction in 29% of cases. Fifty-seven per cent of cardiovascular deaths were due to cardiac conditions, the most common being pulmonary hypertension (31%), dilated cardiomyopathy and chronic rheumatic valvular disease (17% each) and hypertensive heart disease (14%). Forty-nine per cent of subjects were hypertensive, while 40% exhibited benign nephrosclerosis and only 3% of the examined vessels had signs of severe atherosclerosis. Tuberculosis was present in 13% of cases. The clinical diagnosis was the same as the final necropsy diagnosis in 38% of cases. These results emphasise the importance of performing necropsies to obtain reliable mortality statistics.

Evidence of old cerebral infarction of magnetic resonance imaging (MRI) is common in acute stroke patients without a prior history of stroke. This experience led us to investigate the incidence of silent cerebral infarction (SCI) in the patients with essential hypertension, as well-known major predisposing factor for stroke. The incidence, number, size and localization of SCI on MRI (MARK-J, 0.1 T) and the prevalence of risk factors for stroke were investigated both in 66 hypertensive patients (WHO stage I or II; 63 +/- 9 (mean +/- S.D.) years old) and in 42 age-matched normotensive patients (61 +/- 9 years old). Risk factors selected were as follows: diabetes mellitus, hypercholesterolemia, daily alcohol intake, cigarette smoking, obesity, cardiac disease (arrhythmia and ischemic heart disease), hyperuricemia and high hematocrit. In hypertensive patients, the relationships between the incidence of SCI and hypertensive damages in major organs were also investigated. SCI was found in 45 out of the 108 subjects studied and a total of 216 SCI lesions were detected. All of the SCI lesions were localized in the subcortical white matter or in the basal ganglia. All SCI lesions were smaller than 3 cm in diameter and 201 lesions (93%) were smaller than 1 cm. The incidence of SCI tended to be higher in hypertensive patients (47%) than that in normotensives (33%) and increased significantly with advancing age in hypertensives from 26.9% in the 50s to 86.7% in the 70s, while no significant increase was noted in normotensives.(ABSTRACT TRUNCATED AT 250 WORDS)

A baseline examination of all residents aged 40 years and over, in the A-I district, Shibata City, Niigata Prefecture, Japan, was conducted in July 1977. The response rate for this examination was 84.5% for males and 92.6% for females. Nine hundred sixty males and 1,339 females, who were initially free from stroke, constituted the stroke cohort. Similarly 984 males and 1,342 females, who were free from myocardial infarction and angina pectoris on effort, made up the ischemic heart disease cohort. Both cohorts were followed for 10 years through June 1987. It is concluded that, in the agricultural community, the strongest risk factor for not only stroke but ischemic heart disease was hypertension, and that the attribution of hypercholesterolemia and obesity was small. The population that was studied experienced a period of relative economic deprivation before 1950, and there seems to be residual effects from this period to this day. The definition of cerebral infarction used in this study includes several pathologically different types (cerebral infarction of the cortical branches, cerebral infarction of the perforating branches, cerebral embolism and so on), and this may affect the results. On the other hand, the strongest risk factor for ischemic heart disease found in the A-I district is hypertension. This differs from the European/American type of ischemic heart disease, to which hypercholesterolemia and obesity are basic. These results also suggest the possibility that there is a difference not only etiologically but pathologically between the two types.

As part of an epidemiologic cross-sectional study to determine cardiovascular (CV) risk factors in the population (total serum cholesterol, smoking, blood pressure, and body weight) hemoglobin (Hb) and plasma viscosity (PV) were measured. A two-stage cluster sample of 5,312 persons, aged twenty-five to sixty-four (available 5,069) was selected from a mixed urban-rural target population of 282,279 inhabitants, from which 4,022 (79.3%) participated in the study. Patients with chronic myocardial infarction (MI), cerebral infarction (CI), angina pectoris (AP), and peripheral arterial disease (PAD) were identified by questionnaire. The results show that there is no age or sex dependency of PV in healthy participants, while hemoglobin shows the well-known sex difference. In contrast, PV increases continuously with age in the total population. In men, increased PV is found in untreated hypertension, in hypercholesterolemia, and in smokers. In women, it is raised in hypercholesterolemia and in gross obesity. Male MI patients and patients of both sexes after CI in particular show statistically significantly elevated PV. Finally, in male patients with chronic AP or patients of both sexes with PAD, PV is elevated and a tendency to higher Hb values is seen. These results confirm smaller clinical trials suggesting that blood fluidity is pathologically altered in patients with CV risk factors or diseases. Since impaired blood fluidity may worsen the hemodynamic situation, in particular in patients with limited vasomotor reserve, hemorheologic parameters may be of prognostic relevance. Therapeutic implications of these findings should be considered.

A 6.5-year prospective study of cerebral infarction among residents 40 years and older was conducted at the Akadani-Ijimino district in Shibata City, Niigata Prefecture, Japan. The response rate for the initial examination was 85% of 1,182 males and 93% of 1,469 females. Nine hundred and sixty males and 1,339 females who were initially free of stroke were followed up from July 1977 through December 1983. Statistically significant risk factors for cerebral infarction appeared to be age, elevated blood pressure, high R, ST-T changes and atrial fibrillation on ECG, and albuminuria. The ECG abnormalities and albuminuria were due to the high blood pressure persisted over a long period of time. The strength of association of blood pressure with cerebral infarction got weak in comparison with other factors, and funduscopic changes which had been regarded as a risk factor for stroke in 1965-1974 did not reach statistical significance because of the spread of the community-based hypertension control. Even in 1977-1983 when Japanese dietary habits were westernized, neither hyperlipidemia nor obesity appeared to be related to the development of cerebral infarction.

All contributory factors to the unusual occurrence of stroke in young people were evaluated in patients under age 40 admitted to the Stroke Unit of the Austin Hospital in Melbourne, Australia. Over the August 1977 to December 1980 period there were 700 admissions. Of these 14 patients were under the age of 40. There were 7 males and 7 females whose ages ranged from 17-38 years. Each patient was screened for factors which might contribute to premature vascular disease including hypertension, diabetes, smoking, obesity, and hyperlipidemia. In addition, the following tests were performed to exclude an arteritic process: full blood examination; ESR; protein electrophoresis; syphilis serology; and the presence of antinuclear factor. Each of the 14 patients suffered cerebral infarction. A summary of each case is presented in a table. In 9 patients, infarction occurred in the carotid territory of supply. Large cortical infarcts with or without subcortical involvement occurred in cases 1-8, of whom 5 had major vessel occlusion demonstrated angiographically and another had stenosing and ulcerative atheromatous disease at the extracranial carotid bifurcation. In a further 4 patients, infarction occurred within the vertebrobasilar territory and was either confined to the brain stem, the occiptal cortex, or involved both. Angiograms were performed in 2 of these patients and showed irregular narrowing of the vertebral artery which was interpreted as spasm and segmentally narrowing of the basilar artery. The final patient had several ischemic events which included right sided amaurosis fugax, and left frontal, right parieto-occipital and left occipital infarctions. Angiography was normal. All patients survived the stroke and were able to go home. There may be an interrelationship between the pathological findings of Irey et al. (1978) and the effect oral contraceptives (OCs) has on migraine. This is relevant to Case 13. Sustained exposure to OCs may produce the pathological changes described (visible as segmental narrowing angiographically). In 2 patients cerebral infarction was caused by atheromatous or hypertensive occlusive vascular disease. In Case 3 an embolus occluded the middle cerebral artery. Infarction complicating migraine was diagnosed confidently in 4 patients on the basis of typical migrainous symptomatology in the past and accompanying the stroke. Of the 12 patients fully evaluated, there were no cases of polycythemia or thrombocytosis. There were no abnormalities of the clotting factors. Almost every patient had some form of emotional upset, and there were 7 who had significant psychiatric illness and emotional problems of extreme magnitide.
