title: Coxsackie virus heart disease and cardiomyopathy.
abstract: Twenty-two cases of Coxsackie virus heart disease diagnosed from November, 1969, to December, 1971, were re-examined after a period of 42 to 68 months from the acute illness. The patients with hypertension, diabetes, chronic alcohol intake, or aged over 35 were eliminated from the trial. With the purpose of assessing myocardial function, the systolic time intervals were recorded by a noninvasive standard technique. The differences in systolic time intervals between the group of patients with previous viral myocarditis and a group of normal control subjects were not statistically significant. However, the pre-ejection period was clearly prolonged in three patients out of 10, a modification consistent with a depressed myocardial function, as in patients with cardiomyopathy.
