Drinking patterns and preferences among heart patients.

The pattern of alcohol consumption and beverage preferences of heart patients were investigated in 3026 men and 760 women who have had coronary arteriography due to symptoms of coronary heart disease. The younger male heart patients (less than 40 years old) as a group had higher proportion of abstainers and heavy drinkers (more than six drinks daily) than the age-matched reference groups from the general population; the opposite was true for male patients over 60 years of age. The preference for hard liquor (more than 50% of total alcohol intake) tended to rise with age and extent of coronary artery occlusion. Wine as a preferred beverage was reported by approximately 10% of the male patients. The female patients had about twice as high prevalence of abstainers as the male patients.

The probability of surviving coronary bypass surgery. Five-year results from 1,718 patients.

This study of 1,718 men with bypass surgery from 1970 to 1974 in Milwaukee has indicated that the following factors are significantly associated with five-year survival: left ventricular end-diastolic pressure (LVEDP), plasma cholesterol level, coronary occlusion score, age, and left ventricular function (LVF). The 31 men with a previous stroke had a high risk (five-year survival was 32%). To serve as a guide to patient risk, a logistic model is used to predict five-year survival. These probabilities are tabulated for all combinations of LVEDP, age, LVF, occlusion score, and plasma cholesterol level.

Retention or resumption of employment after aortocoronary bypass operations.

Employment status and factors related to resumption of employment were studied in 564 male patients one and four years following an aortocoronary bypass operation. For age categories of less than 55, 55 to 59, and 60 years or older at the time of the operation, 90%, 68%, and 44%, respectively, remained employed four years later. Age at the time of the operation, development of angina pectoris after the operation, a previous myocardial infarction, and the physical requirements of the patient's employment were found to be related to the decision not to work four years after the operation. Of patients not employed prior to the operation, 22% were employed four years later.

Apolipoprotein B (Apo B) in vein graft atherosclerosis. An immunoperoxidase study.

An immunoperoxidase procedure was used to localize the apolipoprotein B in the atherosclerotic lesions of vein grafts removed 5 years after an aortocoronary bypass operation and preserved by embedding in paraffin. Apolipoprotein B was mainly found at the cell-rich interface of the lesion proper and the underlying fibrous tissue. The findings of this study indicate that the immunoperoxidase procedure can be used to investigate the localization of immunoactive components in paraffin-embedded tissue sections.

Prevalence of precipitins in groups at risk of developing hypersensitivity pneumonitis.

A study was made of the prevalence of serum precipitins to Micropolyspora faeni, Thermoactinomyces vulgaris, Aspergillus fumigatus, and pigeon serum in population groups suspected to be at high risk for the development of hypersensitivity pneumonitis. Pigeon breeders' sera contained precipitins mainly to pigeon serum (38%) and A. fumigatus (18%). Occupants of homes in which forced air heating systems were investigated for the presence of microorganisms reacted mostly with M. faeni (13%) and A. fumigatus (8%). Individuals from environments where several cases of hypersensitivity pneumonitis were discovered reacted largely with M. faeni (28%) and T. vulgaris (21%). Sera supplied by physicians from patients with respiratory symptoms reacted primarily to A. fumigatus (24%) and to a lesser extent to M. faeni (16%) and T. vulgaris (9%). The results indicate that the prevalence of precipitins to the tested antigens is not uniform and may be influenced by the environment. Furthermore, the prevalence of precipitins in groups at risk is greater than previously reported for the normal population.

Chronic alcohol abuse and high density lipoprotein cholesterol.

The possible use of high density lipoprotein cholesterol (HDLC) as a marker of alcohol abuse was studied in 92 alcoholic patients entering an inpatient treatment program. The average HDLC levels of 68 male patients (66 +/- 23 mg/dl) and 24 female patients (83 +/- 18 mg/dl) were significantly higher than the values for the corresponding control groups of similar ages. Approximately 20% of the male patients had HDLC levels over the mean +/- 2 SD over the control groups. Following 2 wk of alcohol abstinence, the HDLC levels decreased to the control range. HDLC, as a measure of alcohol abuse, may be especially useful in combination with determination of gamma glutamyl transpeptidase (GGT), since these two tests singly or in combination were elevated in 65% of the male and 85% of the female patients.

A new approach for evaluating risk factors in coronary artery disease: a study of lipid concentrations and severity of disease in 1847 males.

Using recently developed statistical techniques, we estimated joint probability density functions for plasma cholesterol and plasma triglyceride concentrations in 12 subgroups of 1847 males with angiographically demonstrated coronary artery disease. The subjects were grouped by patterns of age, history of hypertension, history of smoking and severity of disease. From the estimated joint probability density functions, we determined the way in which the risk of severe vs moderate coronary artery disease varied with the joint variation of plasma lipids for given combinations of the other risk factors. The patterns of risk that we found are evidence of the complicated way in which the relationship between plasma lipids and the severity of coronary artery disease is affected by other risk factors.

High density lipoprotein cholesterol and coronary artery occlusion.

The relationship between the levels of high density lipoprotein cholesterol (HDLC) and the extent of coronary artery occlusion (ascertained by arteriography) was studied in four hundred male patients. The group with HDLC levels over 50 mg/dl showed a significantly lower coronary artery occlusion score and lower plasma triglyceride levels than the patients with HDLC levels less than 35 mg/dl. The former group also imbibed more alcohol and had less smoking experience.

An assessment of cardiorespiratory adjustments of asthmatic adults to exercise.

The cardiorespiratory adjustments of asthmatic adults to submaximal and maximal workloads were investigated. Cardiorespiratory variables were measured every 2 min during exercise and at the end of maximal physical effort. Exercise-induced asthma (EIA) occurred in all asthmatic subjects while normal subjects maintained normal spirometry. The results suggest that asthmatic adults have no cardiac reserve or oxygen delivery limitations. They work under less efficient ventilatory conditions at submaximal workloads and have a significantly lower functional work capacity. The high degree of correlation between preexercise maximal midexpiratory flow rate (MMF) and maximum O2 consumption (max Vo2) suggests that the smaller airways contribute significantly to the observed abnormalities. We recommend that evaluation of antiasthmatic medications in exercise-induced asthma should take into consideration their effect upon smaller airways and cardiorespiratory variables.

Alcohol and coronary arteries.

The relationship between alcohol intake and the extent of coronary artery occlusion was studied and indicated that the patients who abstained or consumed less than 1 oz of alcohol weekly had significantly higher occlusion scores than those imbibing moderate amounts.

Interrelationship between coronary artery occlusion, high-density lipoprotein cholesterol, and alcohol intake.

The interrelationships between coronary artery occlusion, alcohol consumption, and plasma levels of HDL cholesterol were investigated in 718 male patients undergoing coronary arteriography. A statistically significant inverse relationship was seen between the extent of coronary occlusion and alcohol intake and between coronary occlusion and plasma HDL cholesterol levels. A positive association was observed between the amounts of alcohol consumed and plasma HDL cholesterol levels, as well as between alcohol consumption and history of smoking. The findings of the present study suggest that the "retarding" effect of alcohol on coronary artery disease may be at least partially explained by the alcohol-induced rise of plasma HDL cholesterol.

Early detection of hypersensitivity pneumonitis in office workers.

Symptoms of hypersensitivity pneumonitis in three employees in an office building led to an investigation of their work environment. An open spray water air cooling system was implicated when inhalation challenge with the spray water caused acute illness in one of them. A questionnaire survey of the 4,023 co-workers identified 48 other suspect cases, and laboaratory studies confirmed hypersensitivity pneumonitis in three additional workers of this group. A significant change in pulmonary function, occurring only after exposure to the work environment, was the most useful laboratory finding and was found in five workers with no other pulmonary abnormalities, but not is asymptomatic workers or controls, since five of the six patients with hypersensitivy pneumonitis worked in offices cooled by the spray water system and since three had positive responses to inhalation challenge, use of the spray water system was discontinued. The affected workers improved after they were removed from the office complex.

Pathologic findings in the aortocoronary vein grafts. A scanning electron microscope study.

Examination of totally or partially obstructed human aortocoronary vein grafts, obtained at different time intervals after the bypass operation, has shown that the initial occlusive process is due to thrombosis and may appear a few hours or days after surgery. The cellular phase of intimal proliferation affecting most of the grafts becomes apparent about 4 weeks after the operation. After 1 year the intimal hyperplasia acquires a cell-poor, fibrotic character; the graft usually remains patent. About one-half of the vein grafts obtained 3 or more years after the operation show complicated atherosclerotic lesions. These findings indicate that most of the vein grafts undergo extensive structural changes and some may show similar degenerative lesions as they develop in the coronary arteries.
