A previous study in a car assembly plant showed that production-line workers had a lower incidence rate of heart attacks than executive staff. In the present study some major coronary risk factors and 24-hour ambulatory electrocardiograms were investigated in two age-matched samples of 30 middle-aged men drawn from these occupations. Men with a known history of heart disease were excluded. Compared with production-line workers, executive staff on average had a higher diastolic blood pressure (P less than 0.05) and fewer took heavy exercise during their leisure time (P less than 0.05). Ventricular premature beats (VPB was also similar for each of the periods of work, leisure and sleep. Apart from isolated ectopic beats, disturbances of rhythm were uncommon, and neither VPB nor other arrhythmias appeared to be induced by occupational factors.

In the contemporary United States, mortality is 60% higher for males than for females. Forty percent of the excess of male mortality is due to arteriosclerotic heart disease, which is more common among men in part because they smoke cigarettes more than women do, and apparently also because they more often develop the competitive, aggressive Coronary Prone Behavior Pattern. Men who do not develop this Behavior Pattern may have as low a risk of coronary heart disease as comparable women. Oophorectomy of young women may increase the risk of coronary heart disease, but administration of female hormones generally does not reduce risk. One third of the sex differential in mortality is due to men's higher rates of suicide, fatal motor vehicle and other accidents, cirrhosis of the liver, respiratory cancers and emphysema. Each of these causes of death is linked to behaviours which are encouraged or accepted more in males than in females: using guns, drinking alcohol, smoking, working at hazardous jobs, and seeming to be fearless. Thus, the behaviors expected of males in our society make a major contribution to their elevated mortality.

Deaths from ischemic heart disease(IHD) occurring during a period of one year in Helsinki in persons aged 65 years or younger have been investigated by the Ischaemic Heart Disease Register. Altogether 526 fatalities were registered. Autopsy data were collected in 432 cases, the autopsy rate being 82 percent. The results are presented separately for persons autopsied in the pathologic departments, representing mostly delayed deaths in hospitals, and for medico-legally autopsied persons representing sudden deaths outside hospitals. The diagnosis of IHD death was either based on the positive patho-anatomic or clinical evidence of an acute heart attack or supported by a history of clinical IHD in 92 percent of all registered fatal cases. In the remaining fatalities the possibility of other causes of death had been more or less definitely excluced. All persons with an acute attack of IHD and all autopsied cases showed a division into four socio-economic groups very similar to that of the population of Helsinki. Men belonging to the lowest social group were over-represented among medico-legally autopsied cases. A history of a previous heart disease, visits to a doctor and the use of digitalis were less common in persons autopsied medico-legally than in those autopsied in the pathologic departments. In the former an acute infarction was most often located in the posterior wall and in the latter in the anterior wall of the left ventricle. The prevalence of an occlusion was highest in the right coronary artery in the former and in the left anterior descending coronary artery in the latter; In medico-legally autopsied cases in which a recent myocardial infarction was observed the interventricular septum was involved in 81 percent, but in cases with an old infarction the septum was involved in only 52 percent. No difference in the size of the hearts, the frequency of an old infarction or the prevalence of coronary occlusions was found between persons autopsied in the pathologic and forensic departments. Although a previous angina was about equally common in both sexes, old infarctions were more common in men. The increase in heart weight had occurred proportionally to the same extent in both sexes.

We examined the relations of gender and lipoproteins to subclasses of high density lipoproteins (HDLs) in a cross-sectional sample of moderately overweight men (n = 116) and women (n = 78). The absorbance of protein-stained polyacrylamide gradient gels was used as an index of mass concentrations of HDL at intervals of 0.01 nm across the entire HDL particle size range (7.2-12 nm). At least five HDL subclasses have been identified by their particle sizes: HDL3c (7.2-7.8 nm), HDL3b (7.8-8.2 nm), HDL3a (8.2-8.8 nm), HDL2a (8.8-9.7 nm), and HDL2b (9.7-12 nm). Men had significantly higher HDL3b and significantly lower HDL2a and HDL2b than did women. Correlations of HDL subclasses with concentrations of other lipoprotein variables were generally as strong for gradient gel electrophoresis as for analytical ultracentrifugation measurements of HDL particle distributions. In both sexes, high levels of HDL3b were associated with coronary heart disease risk factors, including high concentrations of triglycerides, apolipoprotein B, small low density lipoproteins, intermediate density lipoproteins, and very low density lipoproteins and low concentrations of HDL2 cholesterol and HDL2 mass. Plasma concentrations of HDL3 cholesterol were unrelated to protein-stained HDL3b levels. HDL3 cholesterol concentrations also did not exhibit the sex difference or the relations with lipoprotein concentrations that characterized HDL3b. Thus, low HDL3b levels may contribute in part to the low heart disease risk in men and women who have high HDL cholesterol. Measurements of HDL3 cholesterol may not identify clinically important relations involving HDL3b.

We compared two ways in which a logistic equation could be used to estimate the number of heart disease events prevented after lowering blood cholesterol levels. Men were selected from an Australian population survey who met the entry criteria of the Lipid Research Clinics Coronary Primary Prevention Trial (LRC-CPPT). The numbers of heart disease events expected over 7.4 years were calculated from the logistic equation after reducing the men's blood cholesterol by the amounts achieved in the LRC-CPPT placebo and treatment groups (our simulated placebo and treatment groups). The number of events prevented was calculated as the absolute difference between the simulated groups (9.48 per 1000 men per 7.4 years) and the percentage difference of the simulated groups multiplied by the observed incidence rate in the LRC-CPPT placebo group (13.66 per 1000 men per 7.4 years). The second estimate was closer to that observed in the LRC-CPPT (17.10 per 1000 men per 7.4 years), and we recommend this approach in cost-effectiveness studies.

The association of serum cholesterol with cause-specific and all-cause mortality was assessed in a cohort of 1,426 men aged 40-59 years who were free of clinically evident heart disease at baseline (1959). A total of 748 deaths (53 percent of the participants) occurred during the 25-year follow-up period. Men with high serum cholesterol levels at baseline had high mortality due to coronary heart disease during both the early and later parts of the follow-up period. In contrast, the association of serum cholesterol with mortality due to causes other than coronary heart disease changed during follow-up (interaction of cholesterol with follow-up period: p = 0.004). During the first 10 years of follow-up, despite their high coronary mortality, men with high cholesterol levels had lower all-cause mortality (age-adjusted relative risk = 0.71 for serum cholesterol above 5.79 mmol/liter vs. below 5.80 mmol/liter; p = 0.03) because of their low cancer mortality (relative risk = 0.55, p = 0.03) and residual mortality (relative risk = 0.49, p less than 0.01). During the last 15 years of follow-up, cholesterol at baseline was no longer associated with mortality due to causes other than coronary heart disease, and consequently, because of their high coronary mortality, men with high cholesterol levels also had higher all-cause mortality (relative risk = 1.22, p = 0.05). The results suggest that to fully analyze the association of serum cholesterol with all-cause mortality, the follow-up period should be sufficiently long--possibly more than 10 years--and the possibility of a change in the direction of the association studied should always be considered.

We investigated the association of systolic and diastolic blood pressure and hypertension with two different manifestations of carotid atherosclerosis in a random population sample of 1165 Eastern Finnish men aged 42, 48, 54 or 60 years, examined in the Kuopio Ischaemic Heart Disease Risk Factor Study. Carotid atherosclerosis was assessed with high-resolution B-mode ultrasonography. Men with a casual sitting systolic blood pressure of 175 mmHg or more had a 3.17-fold (95% confidence interval 1.79-5.61) prevalence of intima-media thickening--adjusted for age, smoking, S-LDL-cholesterol, IHD history and diabetes--compared to men with lower systolic pressures. The relative prevalence of carotid plaques in men with raised systolic pressures. The relative prevalence of carotid plaques in men with raised systolic blood pressure was 2.61 (95% confidence interval 1.44-4.72) in relation to men with no lesions. Our findings suggest that systolic but not diastolic hypertension is associated with an increased prevalence of both early and advanced atherosclerotic lesions in carotid arteries.

Electrophysiologic studies were performed in 134 patients (87 males, mean age 59 years) with unexplained syncope. Seventy-one patients had organic heart disease (ischaemic in 50). Electrophysiologic studies revealed conduction abnormalities and tachyarrhythmias that could account for syncope in 40 patients (30%). Thirty-seven (93%) of these patients received pacing or antiarrhythmic therapy compared with 23 (24%) of the remaining 94 patients who had a negative study and received empiric therapy (P less than 0.0001). Risk of having an abnormal electrophysiologic study was greater in patients with underlying heart disease (P less than 0.05). During a mean follow-up of 22 +/- 17 months, 26 patients (19%) either had recurrent syncope (22 patients) or died (four patients) suddenly. Men had a higher incidence of recurrent syncope than women (26% vs 6%, P less than 0.005). Other clinical characteristics, electrophysiologic findings, final diagnosis and therapy at discharge were not predictive of outcome. We conclude that (1) 19% of patients investigated for syncope will have a recurrent event, (2) female gender may be an independent predictor of favourable outcome.

Several studies have reported high levels of oestrogens--especially oestradiol--in plasma in men surviving an acute myocardial infarction (AMI). We have measured plasma levels of the two major oestrogens, oestrone and oestradiol, for three days during the acute AMI and at three months after discharge. Patients admitted to a coronary care unit with ischaemic heart disease without proof of an infarction and patients without evidence of heart disease served as controls. We found significantly higher oestrone levels during the acute infarction than at three months afterwards and also higher than in men without AMI. Men who died shortly after admission had grossly elevated plasma oestrone concentrations. As oestrone levels were correlated to excretion of catecholamines and cardiac enzyme levels in plasma and as circulating levels of oestrone are influenced by ACTH, the hyperoestronaemia may reflect stress-induced increased adrenocortical activity. Plasma oestradiol concentrations in men with AMI decreased significantly during the first three days after admission. In men given no medication oestradiol concentrations did not differ significantly from those in the control groups. Three months after the infarction, the median plasma oestradiol (but not oestrone) concentrations were significantly elevated, but not if only data from men given no medication were considered.

We investigated the association of elevated serum low density lipoprotein (LDL) cholesterol levels, smoking and hypertension with different manifestations of carotid atherosclerosis in a population-based sample of 720 Eastern Finnish men aged 42, 48, 54 or 60 years, examined in the Kuopio Ischaemic Heart Disease Risk Factor Study. Carotid atherosclerosis was assessed with high-resolution B-mode ultrasonography. Men who had neither a history nor symptoms of cardiovascular disease with serum LDL cholesterol concentration in the highest tertile (4.17 mM or more) had 3.40-fold (95% confidence interval (CI) 1.98-5.84) age-, smoking- and hypertension-adjusted probability of intimal-medial thickening as compared to men in the lowest serum LDL cholesterol tertile. The odds ratio for carotid plaque versus intimal-medial thickening was only 1.03 (95% CI 0.47-2.28). The respective odds ratios for smoking (28 pack-years or more) were 1.62 (95% CI 0.79-3.32) and 3.02 (95% CI 1.41-6.47) and those for hypertension were 1.10 (95% CI 0.70-1.73) and 0.99 (95% CI 0.53-1.84). Our findings suggest that elevated serum LDL cholesterol concentration associates with an increased risk of common carotid arterial wall thickening, whereas smoking is associated more strongly with carotid plaques than intimal-medial thickening. Our cross-sectional data do not support association between hypertension and either manifestation of carotid atherosclerosis.
