To the Editor:—
We were sorry to learn of the death of Dr. Samuel A. Levine, particularly since his teaching and writing have been an inspiration to us. Perhaps one of the last things that he wrote was the editorial, "Elusive Errors in Coronary Statistics" (195:860, 1966) in which he referred to our article, "Studies of Male Survivors of Myocardial Infarction: IV. Serum Lipids and Five-Year Survival" (Circulation31:854, 1965). Dr. Levine made the important point that overall prognosis in coronary patients can be studied only in unselected, consecutive cases of coronary heart disease. We should like to amplify his remarks and suggest that it requires prospective and follow-up study of healthy individuals in a cross-section of an entire community to determine true, overall prognosis in coronary disease.1 Only in this way are silent infarcts and sudden deaths from first coronary episodes included in the mortality data.
