A case is reported in which a nonspecific type of myocarditis and less marked nonspecific changes in the lungs and liver were the pathologic findings. The lesions in the heart musclee were severe enough to account for the patient’s sudden death after a short illness with vague symptoms. AUTHORS.

Acute myocardial infarction is preceded by premonitory symptoms in a goodly percentage of cases. In a patient previously well, cardiac pain, however brief and mild, suddenly appearing during rest or customary activity, may imply existing or imminent myocardial infarction. In a case of pre-existing angina pect,oris, cardiac pain, more readily precipitated by effort or beginning to occur at rest, may imply existing or imminent myocardial infarction. In considering symptoms suspected as premonitory it must be recognized that myocardial infarction does not inevitably follow them, but the strong possibility that it may should lead to heightened suspicion and therapeutic precautions.
