TLDR
Twenty-year coronary heart disease (CHD) incidence is analyzed for 279 men, CHD-free at the ages of 47 through 57 years and characterized by three examinations before 20 annual follow-up examinations, yielding satisfactory agreement between observed and predicted distributions of CHD cases in classes of estimated risk.Abstract:
Twenty-year coronary heart disease (CHD) incidence is analyzed for 279 men, CHD-free at the ages of 47 through 57 years and characterized by three examinations before 20 annual follow-up examinations. Sixty men developed CHD, 42 dying or suffering infarction. Among 20 entry characteristics, three had major predictive power, especially for CHD death or infarction: cold pressor test, a high level of serum cholesterol, and systolic blood pressure. Smoking and relative weight seemed unimportant. Major CHD incidence was proportional to cholesterol to the 3.4 power. Five-variable multiple logistic analysis permitted placement of men into deciles of estimated risk differing more than tenfold in CHD incidence. The combination of only cholesterol and systolic pressure was nearly as good. The multiple logistic coefficients applied to five-year data on 1,287 men among whom 182 CHD developed in 182 yielded satisfactory agreement between observed and predicted distributions of CHD cases in classes of estimated risk.read more

Health complaints, stress, and distress: exploring the central role of negative affectivity.
David Watson,James W. Pennebaker +1 more
TL;DR: Results demonstrate the importance of including different types of health measures in health psychology research, and indicate that self-report health measures reflect a pervasive mood disposition of negative affectivity (NA), which will act as a general nuisance factor in health research.

Impact of psychological factors on the pathogenesis of cardiovascular disease and implications for therapy.
TL;DR: Suggestions to improve the assessment of behavioral interventions include more complete delineation of the physiological mechanisms by which such interventions might work; increased use of new, more convenient "alternative" end points for behavioral intervention trials; development of specifically targeted behavioral interventions (based on profiling of patient factors); and evaluation of previously developed models of predicting behavioral change.

Indices of relative weight and obesity
TL;DR: The body mass index seems preferable over other indices of relative weight on these grounds as well as on the simplicity of the calculation and, in contrast to percentage of average weight, the applicability to all populations at all times.

Cardiovascular reactivity and development of preclinical and clinical disease states

TL;DR: There is reasonable evidence to suggest that cardiovascular reactivity can predict the development of some preclinical states and perhaps even new clinical events in some patients with essential hypertension or coronary heart disease.

A simplified method for the estimation of total cholesterol in serum and demonstration of its specificity.
TL;DR: The simplified but precise method described in this paper involves treatment of the serum with alcoholic potassium hydroxide to liberate the cholesterol from the lipoprotein complexes and to saponify the cholesterol esters.

Estimation of the probability of an event as a function of several independent variables
TL;DR: A recursive approach based on Kalman's work in linear dynamic filtering and prediction is applied, derivable also from the work of Swerling (1959), which provides an example of many other possible uses of recursive techniques in nonlinear estimation and in related areas.
