The authors examine the utility of factor analysis for identifying characteristics of a patient population that are reliably predictive of prognosis or useful for estimating risks of morbidity or mortality. This technique involves grouping the most h

The purpose of this study was to examine the clinical outcome of acute myocardial infarction among women of three ethnic/racial groups and to determine whether observed differences in outcome are explained by differences in associated risk factors. N

Atherosclerosis has been studied by femoral angiography in men with myocardial infarction. Smoking history recorded at entry was the strongest variable asssociated with degree of atherosclerosis at the first angiogram. This correlation was significan

The step from coronary angiography to surgery is taken primarily on the basis of the ejection fraction (EF) and number of diseased vessels (NV), taken jointly as coronary status (CS). This study reviewed (1) how well EF, NV and CS are estimated from

Femoral angiograms were made in 21 cadavers under conditions which simulated clinical films. Then these arteries were excised, laid open, and color photographed along side of corresponding casts of the arterial lumen. Twenty-seven segments, 5 cm long

A computer method for detection and quantification of atherosclerosis from angiograms has been developed and used to measure lesion change in human clinical trials. The technique involves tracking the vessel edges and measuring individual lesions as

Comparison of coronary atherosclerosis change in a pilot angiographic study of retrospectively matched smokers and controls indicates more rapid progression in smokers. The findings indicate the feasibility of small-scale angiographic trials of treat

With use of the serum protein pattern as a model, we compared the "Diagnostic Effectiveness" of tests of different chemical specificity—i.e., the percentage classified correctly according to the clinical diagnosis. When results obtained from a sele

The steepest ascent, univariate, factorial, and random methods for seeking maxima were compared by trying versions of them in several two-factor situations, with and without experimental error. Of the two sequential methods, the steepest ascent was b
