Cholesteric liquid crystals encapsulated onto strips of black mylar sheeting, with a discriminating temperature range of 30 to 37 C, were used to map thoracic thermographic patterns in 17 patients during the pain of angina pectoris induced in 14 by exercise, in 2 patients with acute myocardial infarction, and in 5 patients with acute pericarditis. Criteria of abnormality were twofold: When skin over the mediastinum was cooler than skin over the lung fields; and thermographic assymmetery, except that heart heat can extend further to the left than to the right (asymmetry less than 1C). Simple cardiomegaly had no consistent relationship
