Notes on the coronary arteries.

Dock recorded one of the earliest diagnoses of myocardial infaction in a living patient: "The diagnosis was mymalacia folling coronary sclerosis with secondary pericarditis. This was based on the history of increasing dyspnea and heart pain, without evidence of disease in lungs or kidneys, or other (valvular) diseases of the heart. the history of the acute attack indicating infaction, and the acute onset of pericarditis without other cause." As historian Joshua Leibowitz commented, "this concise diagnosis, logically derived, formulated in scientific terms, and made at the bedside, is one of the first clear-cut and definitive modern contributions to our subject [the history of coronary heart disease]" (quoted by W. Bruce Fye).
