Centenary of the first correct antemortem diagnosis of coronary thrombosis by Adam Hammer (1818--1878): English translation of the original report.

William Heberden (1710--1801), in 1768, described angina pectoris, the classic symptom of ischemic heart disease, 150 years after the discovery of the coronary circulation by William Harvey (1578-1657). Another 110 years had elapsed before the first antemortem diagnosis (confirmed at autopsy) of coronary thrombosis was reported by Adam Hammer in 1878. The patient was a 34 year old man who died some 19 hours after a sudden collapse. Although the patient's clinical features were atypical (such as the absence of angina and the presence of complete heart block) and the autopsy showed vegetative aortic endocarditis that appeared to be causally related to the thrombotic coronary occlusion, Hammer's astute and carefully reasoned bedside diagnosis was history-making and deserves to be so recognized.
